iPhone 4S Akku tauschen

I have replaced my battery which is now powered fine but I now don't have a phone signal which is "searching" can anyone advise?

People should be advised that the screwdrivers provided with the iFixit battery replacement fix kit are slightly magnetized, which was a surprise. So touching anything except the screws themselves with them is a bad idea.

Another general comment about this guide: the photos are very nice, but it would be extremely foolish to open your phone and remove the battery while holding it in your hands, as is depicted. Work on a flat, clean, open table top to minimize the chance of losing any screws or other parts.

i didn't know what possibly went wrong, i enclose the assembly and there's no gsm signal, so i re-open the back cover and install it again, then the signal comes right back.

I was a bit confused, as my Battery APN was 616-0582, which was not listed on the "Replacements Battery Parts" which is sold here. Only Apple Part #: 616-0580, 616-0579, 616-0581 are listed there. But The 79 I bought works like a charm as a replacement of my 82. At least after restarting after I got a "searching" in the first two minutes.

After I replaced the battery according to these instructions, I, too, had the scary "searching" error when looking for my service provider, even though my 4G was available. I plugged the phone into my computer and rebooted the phone. When it came back on, my provider showed right up. All is well. Do watch for that little black and gold thingy...it's teeny, and comes loose no matter what you do. Just pin it between the phone and connector on the top screw, with that little gold dot facing you. Put the screw in to hold it in place.

This was so easy! Slow and careful. The longest bit was getting the battery off of the adhesive.

It's medium in difficulty but it is my first repair! :)

It's a easy work

Just changed my battery.

I concur with others regarding the "No Service" issue after restarting. Before tearing it down again to check the antenna connection, I rebooted the Phone and then the second time I had service. So if you are fairly confident of your handiwork then definitely try this first!

As others have stated it is worth keeping a very close eye on the black earthing clip and it's positioning before removal. It is held down with the top screw and must be repositioned before the screw is fitted. I used the thinnest end of the Plastic Opening Tool to slide into the fold of the earthing clip in order to guide it into place. My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver.

Thanks ifixit!

This worked wonderfully for me!

My iPhone 4s battery was discharging very rapidly since I installed iOS 7. Although I'd read reports that it's a software problem with the latest iOS, the phone is over two years old.

This repair has greatly improved my phone's battery life. Before I replaced the battery, when the phone reached ~7%, it would shut off at any time, and I could only use it for about two hours. The battery can now deplete all the way to 1% and I have much more battery life. I'm very happy with the battery kit from iFixit; it's revitalized my phone.

The battery replacement isn't easy -- the screws are very small indeed. The "pressure contact" popped out when I disconnected the battery. I had to look at the high resolution iFixit image to understand its replacement. To replace, first attach the battery connection, and then slide the "pressure contact" beneath the top screw of the battery connection. Fine-nosed tweezers make this much easier than fingers.

easy and quickly replaced the battery. thanks for your helpful guide.

The installation worked well for me. I did use latex gloves to avoid the transfer of oil from my skin to the device parts. The screws, particularly on the inside of the device, are tiny so it is really important to have good lighting. A free-standing shop magnifying glass would make the process of inserting the screws easier.

I just completed the replacement. The first time the device would not power on without a power cord connected. There was no service and I was unable to activate Wi-Fi. So I opened the phone up again, removed the battery connector, aligned the ground clip and cleaned it with alcohol. This time the phone was able to boot without the power cord attached, but the screen was flickering like !@#$ around the corners. Wi-Fi worked and so did service. After a minute I noticed that the flickering was less noticeable and now after 30 minutes it's completely gone. So if you have the flickering issue, just wait a few minutes.

Extremely good guide - took all of 10 minutes to change the battery without any issues. As always just ensure you have all the right tools and worth reading through other members comments. Well done iFixIt!

An easier repair than I anticipated. My advice is once you get the back off, take a minute to study the orientation of the battery connector and the small black ground clip underneath the top screw; it will inevitably pop out of position when removing the battery thus requiring realignment. Go slow and use minimal force when prying both the battery connector and battery. After powering on the phone, I too had the problem of acquiring a cell signal. After five minutes of the phone displaying "Searching," I did a reset (holding sleep/wake button and home button simultaneously) and when phone powered back on I immediately received a signal from my carrier. Looking forward to greater battery life between charges.

- I had the same issue with "searching" network and I was *unable* to address it by: (i) resetting the network settings, (ii) removing the SIM card, (III) connecting my iPhone to iTunes, and (iv) setting the time automatically.

- Eventually, I had to manually set the date (especially the year) and time to the right settings, then reboot.

- After that everything got back to normal.

just completed this very easy battery replacement on my daughters iPhone 4s. Steps are really easy to follow, one thing I found helpful was to use a tweezers to put the pressure contact back underneath the top screw of the battery connector!

This is soooooo easy.

I also had the 'Searching' issue.

Powered down, and back up again and all was fine.

Shame on Apple for making this appear to be elusive.

I did use a magnifying light, and a pair of needle nose type tweezers for the pressure contact. I also cleaned the back and the connectors with alcohol like they recommended, but not sure if it made any difference.

Well done ifixit!

Followed instructions and had a perfect installation. Two tips: before unscrewing the battery clips, pry up the battery to loosen it from the adhesive, carefully. Then unscrew the clip and carefully pry it up. That way, there's no frantic popping of the grounding clip. Then pull off the battery. Also, once put back together, power up, then remove the SIM card and reinstall (like everyone else is doing). Presto, new battery and fully functioning iPhone 4s.

Just recieved my battery. Replaced it very fast. The instructions were perfect. Now the only thing is if the battery is good, but that's not an object to the guide.

Thanks!

Both of the battery are made in China.The battery which assemble in the 4s is produced by amperex technology limited, the ifixit replace battery is produced by SONY electronic(wu xi)limited.

Procedure was easy with two caveats:

1) I needed a small pair of needle-nosed pliers to remove and reinsert the pressure contact.

2) It took quite a bit of pressure to release the battery from its adhesive.

Everything went super simple. Before I shut down my phone I put it in airplane mode, after turning the phone back on I took it off airplane mode and everything was working perfect. I did not experience the network problem, this may be the trick.

15 minutes to change the battery.

No problem, it was like a child game!

After switch on a first time, my phone doesn't find the network...

I switch off and on and it find the network immediatly ;)

Thanks.

I have just replaced the battery in my son's i4s using this guide it took me approx 15 minutes. Once done phone turned on as normal but did take about 5 minutes to find the network. Thanks for the guide it was a massive asset.

Installation seemed fairly simple for it being my first time. I had some issues with the LCD Glitching a bit but after a few hours it went away. I'm currently monitoring the battery life right now with the app called Battery Doctor. I will post a reply in a few days. I would recommend reading through the comments before installation!

It was harder than I thought it would be... the screws are so super tiny! I had to curse quite a lot to get them back in :)

My advice: DON'T DRINK COFFEE BEFORE replacing your battery! :)

I also had the "searching" problem, and at first my phone wouldn't connect to itunes (error message), but after resetting network settings and restarting my phone, all went back to normal. Curious how long my battery will last!

Thanks a lot from cold Germany - worked like a charm, took about 20 min with one interruption (soccer game on tv). Was my first try on an iPhone, and yes, the screws are tiny, and yes, you definitely need some extra light and a magnifying glass if you are over 22 :-D. I also had the issue with "searching network". After resetting the network settings it did work instantly! Keep on with the great work here at ifixit !

Just got my kit, followed the instructions and had 0 problems except could use larger photos of the inside of the phone as we are going along. Oh and the pressure contact - I never did touch it with anything other than the plastic tool of the screw driver. Not quite clear what position that was in from the pictures, could use a close up there too. Otherwise iFixed IT!

It took approximately 15 minutes. I watched a video on youtube where a guy was replacing the battery with the one bought from ifixit. All occured without any problems, very well. I appreciated the way the battery was packed and the fast shipping. Thank you ifixit !

Battery replacement straightforward and no dramas. I had done the pre-reading (i.e. this guide and all the comments) and was ready for the black/gold bit to sproing across the room, which it didn't. Steps very easy as above. I removed the black/gold thing from the phone while I was taking the old battery out so I didn't lose it.

All went back together smoothly - I used a couple of toothpicks to align the black/gold thing + the connector from the battery before screwing them in - the ribbon on the connector was stiff and I was reluctant to be too heavy handed trying to force it in. So gently pushed it into place, screwed back in, back cover on and away we went.

Phone came back to life with 75% battery life and found my network with no dramas. All in all done before the children could come and have a look at what I was doing (10-15 min tops).

Many thanks - now to repair the broken iPad glass.

I had a 2,5 year old iPhone 4s.

Ordered new battery + kit.

Changed it.

A few restartes, sync with iTunes.

Perfect!

Now I got a new working battery!

Does anyone know what the little green chip with the black chip on top is? It is on the visible part of the logic board just below the screw that holds the serial number plate on.

i am sorry for you- My advise is, never bay a appleprodukt again. I surely won´t- It is so sad to fool consumer like this.

My 4s got submerged in water and I replaced the battery. Afterwards, when I attempted to turn it on. The apple showed up on the screen but no more. I took the battery out and charged it in another phone and then put the charged battery into the phone again. Once again when I tried to turn it on, the apple appeared and no more.

This phone has so many pictures of my children and important messages on it that I would like to retrieve. Any suggestions on what I should do to get this phone working again?

Just did the replacement in about 15 minutes. A few notes:

1) Having a magnifier that you don't have to hold in your hand is key. I have a set of pivoting jewelers lenses that clip on to my reading glasses.

2) The Phillips screwdriver that comes with the "Liberation" kit is crap. Blunt, crude, wrong tip angle. Unusable. Get a set of real, or even semi-real fine screwdrivers.

3) establish a wide, open, clean area for working. If one of those little screws skitters out of your grip you don't want to be searching under table debris for it.

4) Pointy tweezers. With the size of the screws in this thing they won't seem so pointy.

5) The instructions above are vague about how the battery connector gets pulled off or pushed on. I still can't quite figure out the combination of sideways and up that worked. I ended up using the plastic tool to lever the connector to the right, while lifting...no, that wasn't it.

I have to be honest, I went to the trouble of changing my battery using an ifixit kit but the new battery had no better life than the one I was replacing. I've been through so many guides trying to figure out if there is some setting I've got it on that drains battery life but I can't find anything. Meanwhile, I didn't have a warranty to invalidate, so to speak, but my only chance to rescue my phone now is to take a gamble that my insurance providers will be able to fix it. Now I'm worried that I'll have invalidated that policy. I LOVE the idea of ifixit's battery replacement kit as much as I'd love to stick it to Crapple but I'm afraid for me, this kit wasn't worth the money or the hassle. But on a side note, I'd like to urge anyone read this to avoid Crapple products. They're designed to fail so that you just buy more of their products but I will absolutely not be giving them any more of my money. Thanks anyway ifixit.

Ok, so wash your hands. Get everything on a flat surface before you dig in. Great directions except I would add that prior to removing the battery connector cover, take note of the little black ground clip (with the gold contact point) which gets attached under the top screw. I had a hard time getting this back in place as I didn't notice exactly where it was prior to removing the battery connector cover. These directions are great otherwise. Thanks for saving me some moola by letting me replace the battery myself!

Be very careful as to where you decide to do the repair. I dropped one of the internal screws doing mine and my roommates and I spent a good half hour scouring the kitchen/dining room floor for the 1.5mm screw. Using a towel under your phone while doing the repair was an easy way to keep screws from bouncing away when I inevitably dropped them again.

Couldn't have gone easier or better. One repaired iphone :)

thank you

That was INCREDIBLY easy to do, thanks to both your instructions and people's comments. 10-15 minutes, start to finish. Tweezers and a good set of bifocals helped too :-)

It's very basic. Thank you so much fixers.

With the help of a youtube video (https://www.youtube.com/watch?v=nYYdbk3U...) I got the battery replaced fine - but also had the "No Service" / Searching problem others have commented on ...

To round off the battery replacement instructions, it would be good to indicate to users that:

1) the Time & Date are set back to 1 January 1970 when the battery of the iPhone is replaced

2) to fix this, it's easiest to sync in iTunes ...

3) if the "No Service" / Searching problem persists, power down & up a few times

That worked for me ...

Thanks ifixit for the great product & service!

i swapped the battery y only have one problem with

that stubborn bottom screw from the battery connector

i had to get creative to remove it

other than that it just took like 10 minutes or so

i'm super happy with this new battery

thanks so much ifixit greetings from Mexico

Hello, I was not able to remove one of the two screw once phones open, impossible. It became smooth. Can you help me? I think of having damaged the battery by forcing to remove the screw, and my iPhone does not light up any more.

I did this with a couple of hitches. The battery glue sticks like sh1t to a blanket so I broke both my plastic tools trying to pry it out. I used the screwdriver to pry the battery after that and I got a spark, but fortunately I didn't fry anything.

The takeaway:

Go gently with the plastic tools

DON'T USE METAL TOOLS WHEN PRYING THE BATTERY!

The "No Service" error may come up after the replacement. As others have mentioned, restarting the phone again is the best first step. Then reset the network settings if that fails. I tried to edit this into the guide but it got rejected. I've seen other guides missing software next steps as well and then have to dig through the comments or search elsewhere for a solution. Not sure why iFixit doesn't want software steps in the guides as it is an important step to a solution.

Took me about 10 mins to do. Simple and works like a charm.

Same here. Replacement was relatively easy, took 10 minutes and works fine.

Very easy. Go ahead and do it. If your phone doesn't get connected and you are sure everything is in place, just sync with iTunes and reboot. Thanks for the gummy bears.

Just changed the battery 15 minutes ago and everything still works (so far). Since I'm so extremely near-sighted, I found it a lot easier to take off my glasses and go through all the steps dealing the screws and the ground clip having my nose about 5 centimeters from the phone. So glad I finally did this. I was going from 100% to 45% just getting up, leaving my house and riding the train to work (less than 2 hours). Hope I can keep it working. I stopped at the Apple store today and priced out the 6 and 6 Plus and %#*@, the exchange rate makes them so fricking expensive - nearly ¥100,000 for the 128G 6 Plus. That's the equivilent of about $1,000 under a standard 2-year contract like in the States.

I did find that the phone took way to long to find the network again and when it did it was 2 bars short of full power which wasnt the case beforemso I went into the phones settings into network then reset the phones network settings and restarted the phone like a normal computer.

It was much faster this time.

The instructions were good and everything works fine after the replacement. I had the often reported issue "searching network". After resetting the network settings it works perfectly again. Thanks.

I flawlessly replaced the battery my first try thanks to this guide.

Super easy. Took about 15 minutes. Once I turned phone back on it kept searching. I turned on airplane mode and then turned airplane mode off and it connected immediately. Now to see if the new battery makes a difference. Otherwise I may need a new phone.

It works! The guide is really helpful, the kit brought everything I needed and more, and... everything came out perfectly!

I had the advantage of already owning the iFixit Pro Toolkit before I started so I was able to remove the spring contact under the top screw with the curved tweezers (and re-position it before putting the screw back in). I also used the tweezers to gently hold the contact still while I tightened the top screw. I also had the 'Searching' issue on bootup but I figured it was a network contact initialization issue since the network data would be wiped so I set the phone to Airplane Mode for about 15 seconds and then switched it back. It connected instantly. Hope this helps.

the phillips screwdriver they reo=commend and then sell you does not work on the battery connector screws! beware!

Relatively easy task, the only additional tool I used was tweezers in order to place the ground clip back in the correct location. Other than that the process only took ten to fifteen minutes, thanks for the nice toolkit and guide!

Once iFixit sent me the right screwdriver (don;t get the cheap open, get the pro grade) I was able to do the swap in less than ten minutes. It's easy, and I'm an idiot, so do it yourself and don;t pay someone to do it for you.

Nice guide. I had a trouble free install (other than getting the tiny screws stuck between the battery and the rest of the assembly and needing to take my glasses off and peer intently with one eye into the iPhone - ah, the joys of ageing). But watch out for that little pressure contact - mine popped out and away when I was prying open the battery connector. Thanks folks for a great guide and also parts kit!

I just got my phone working again after switching the battery. Lets see what my new battery life is like. @ifixit: You need to include some of the feedback from users into the guides

I just changed the battery. The guide is complete and really well done (as usual)

10 minutes of work, iPhone working fine, no need to reboot.

Compared to my previuos iFix-experience (swapping the motherboard of a PowerBook) this has been like a walk in the park...

Everything went perfect. My only advise is to have a lot of light, magnifying glass, reading glasses, tweezers and good clean work area. So simple to do and took about 15 minutes. No doubt this is a do it yourself task. Great battery kit and instructions. Thanks ifixit...

The guide was good but I found the youtube video more helpful, especially since the piece on that got moved on the video happened to me as well, so I was able to see how to put it back. It's been so long since my battery was properly working, that I am not sure if this new one is good. When I turned on the phone it was at 76%. I let it drain completely yesterday before charging it overnight. It's only half way through the day and it's down to 32%. Is this normal? I've not used it overly today. How often should a charge last for relatively average usage (checking emails, online a bit, texting)?

Could thenew battery be bad? I'm going to give it a few more days and monitor it.

The kit itself was pretty easy to use, the biggest issue being my eyesight isn't what it used to be, so thankfully had a friend to help. Just hoping the battery is ok and I don't have to do it all again.

Excellent guide. This is so easy to follow and do. It took approximately 15 minutes. I also watched a video on youtube where a guy was replacing the battery.

http://www.cnet.com/au/news/how-i-replac...

I did encounter the "Searching" problem on re-start. The phone could not find my service provider, but the fix was very simple, I just re-booted the phone and it was back to normal.

I have replaced battery and it seemed to work, then i tightened down the screws and now nothing will show up on the screen like its not getting power, any ideas?

Very easy to do with help of the kit. I also replaced the screws but honestly i dont see the point. The philips screws are more fragile in my opinion. And as somebody else said, if your eyesight is bad, use glasses. The screws are so tiny!

Good stuff, great. A recommenation: Take a sheet of paper, put the stuff you dismantel on it, put a circle around it for each step and add the number. This will help during reassembly, especially the 2 different screws in step 4. Greetings from an old? (>60) German.

Instructions were great!. The pressure plate come off when removing the battery. Use fine tweezers to replace and orient. A good light and magnification are also very helpful.

Received the kit to replace a 4s battery today. After reading through the instructions and comments, the task only took about 10 minutes. Very easy.

Less than 5mins total. Just did it and looking forward to a longer battery life between charges.

I followed the instructions but am unable to get the phone to power on unless it is connected to a alternate power source,tried rebooting phone, I still get the same result,

When I unplug phone it loses power and goes dark,battery meter on phone says it's fully charged! Does SIM card need to be reinstalled before powering phone on?

In general: Watch several videos before diving in. Wash your hands, and/or put on some snug fitting nitrile gloves. If your eyesight is not what it used to be, then use a magnifying light lamp or perform in a very well lit area. Re: Step 1 - At first glance, the two screwdrivers included in the kit look very similar; in order to avoid confusing the two, place a piece of colored tape on one of them. RE: Step 2 - push gently with two thumbs, but don't overdo it. The back plate will only slide forward 2mm - a very small space. Re: Steps 4 & 5 - Recommend using the kit box, or several small trays to set aside the 2 battery connector screws and pressure contact plate. These pieces are very small! The kit's screwdrivers are magnetized to hold the screws, but not the plate. Re: Step 7 - Some of the battery adhesive may come loose from the phone and battery, and ball up into a wad. An exacto knife can be used to gently excise any wadded up portions of adhesive.

Just received my replacement kit for iPhone 4s in the mail. Had the new battery in and working within 20 minutes and I'm no expert. I would HIGHLY recommend anyone having issues with their iPhone 4s battery to purchase the kit and make this fix.

Brilliant ... easy to follow ... had screw head strip (lower battery connector) but got it out ok in the end ... (gentle pressure)

On re starting phone it couldn't get signal ..just searching ... did "hard reset" and it was fine ... excellent !

You need good magnifying glass if your eyes aren't perfect ! (maybe even if they are)

Is there a trick to get the corner screw by the headphone jack in the bezel w/o having to remove parts around it. I just cannot seem to get the screw to thread correctly

I am using the PH000 head that came with the 54 bit driver kit.

Thanks for this how-to. I just replaced my battery and it started up with 56% power. How can I test this new battery to be sure it is a new battery?

Muy sencillos los pasos para realizar este cambio por una nueva batería, por ser un equipo ya viejo el iPhone 4s, me pareció muy buen precio los 25 USD por el paquete de liberación y el cambio de la batería, lo que más tarde por supuesto, fue encontrar el primer tornillo de la tapa, por más que lo quiero hacer con cuidado, se me cayó un tornillo que al final deje en el blister del paquete de liberación del cambio de los tornillos. en una semana diré si la batería me dio el performance que requiero para mi teléfono.

Everything went great, except the common issue, that the iPhone would not connect to the providers network (no information about locked Sim also). Setting the date and time to manual and correct information before shut-down and restart fixed that problem…

I can't believe I waited this long to swap my battery. The repair was easy using the kit with included tools. I had the phone apart and back together in about 10 minutes and I was working slowly so I didn't make a mistake. The only challenge was prying the old battery out. The plastic tool worked well, you just gently apply pressure as described in the guide. Now I am going to fix my old ipod.

Just changed out my battery in the 4s. Took about 10 minutes using the guide. I put the phone in airplane mode before doing a hard shutoff and the phone worked perfectly with no network issues. Charging it up now to see how much longer it's going to last...

I suspect this guide is clearest to those with a bit of experience with electronics. Crystal clear, that is. This is not a difficult fix. Just use common sense and make sure your tabletop is secure!

I'm 57 and trying this without jewellers glasses was a mistake. The screws are TINY. I've worked on computers for years but never with screws THIS small! If your eyes aren't 20/20 get magnification for sure. The kit I got was from BattDepot and only came with one size of screwdriver. There are two sizes required. Dumb!! And the one screwdriver isn't magnetized so getting the screws back in has been a beggar. Good luck with your install. Mine's been more difficult than expected. (Should have bought the iFixit kit!)

Hi.

My iPhone worked well except the fact that the battery was very used.

I change my battery by following these instructions and I succeed to disassemble and reassemble my iPhone without any difficulty. However, after having turned on my device, the cellular connection didn't work with the new battery. As written in the tutorial, I tried to restore the device using iTunes (in DFU mode and not). This message appear: "the iphone could not be restored: an unknown error occurred (1)".

What is the solution to solve this problem ?

Hi.

I replaced the battery but the phone did not start. I plugged it, turned it on but it stayed with the apple screen, after 30 minutes, the same, black screen and white apple logo. I replaced it back with the old battery and everything worked fine. any idea?

Really easy. Recommendation: READ the comments! They were really helpful and gave me faith when the 4S refused to connect to the carrier. I plugged it into iTunes as stated, then hard reset it (no reset of network settings), and then it was working like a charm again.

My iPhone is about 2 1/2 years old and battery life is getting a lot poorer, drains fast on standby and shuts off at 20%. Followed the instructions and like most it went well but had no carrier signal the first time. Took advice on bending the grounding pin up more, and that fixed the issue. I suggest that the instructions be revised stressing the importance of this ground pin, and noting that not having it positioned correctly results in the no signal issue.

During the past year I would go to take a photo with my 4s and the battery read 45-60 %. As soon as I would take the 1st photo the battery would die! I an confident the battery replacement will eliminate this from happening. Battery has been replaced and is now recharging. What I did use was a toothpick to align the upper screw socket with the metal connections. The replacement took 20 minutes as I took my time and paid attention to the task at hand. Do read all of the help before you start.

I did it! No Signal issue was fixed after rebooting once.

This was my first repair and I nailed it :)

Also, I recommend using latex gloves. ^_^

Just sent email to iFixit to see if they will send me another replacement battery. First thing that should be note I purchased my kit in February of 2015. Got and installed what looked to be a new battery. Very happy in with kit and installing battery was simple. Worked great for a while but less than 3 months battery died completely. Not charging and dying when phone at 21%. Just pulled old battery out of box and reinstalled since it does work and takes a charge while I wait for another replacement battery. ONE biggie new replacement battery was manufactured 01/2013 and old battery is 03/2013. Didn't realize til swapping batteries second time. BUYER BEWARE THAT REPLACEMENT BATTERIES ARE NOT NEW BUT USED BATTERIES.

took out the original battery and put in the new one, phone turned on and said 'searching'. I turned it back off and took out the screws again and pushed down the signal clip more and made sure the screws and pressure clip were correct. then I put everything back; PUT THE BACK ON, and worked fine. signal and wifi both working fine. please remember that the GROUNDING clip needs to be grounding to something: there is a metallic strip on the back part of your phone, in which its grounding to. you need to have your back on to make everything work, don't turn it on without the back on to see if it works because you may have issues. easy tutorial just take your time

Awesome instructions....clear, easy to read and great pictures! So glad you guys are in business!

Noticed someone else talking about pressure contact....that was in the version of the Iphone 4S I replaced the battery. Yes you will need tweezers and it goes under the battery contact/attachment connector. So please note that before you remove battery.

I was a little uncertain on the instructions but managed to remove the old one and install the new one and it works great!

Great guide! The only problem with me is that they sent me a 1.5mm star-shaped screwdriver, instead of the 1.5mm Phillip's screwdriver. I had to buy another one, which was pretty hard to find. Other than that it was great! My Iphone works like new! Thank you!

This was my first repair and I had no problems. Cycle count was at 1 and it took a total of 20 minutes. This video was helpful: https://www.youtube.com/watch?v=xJSSFZbr...

10 minutes tops. notes:

The white towel under the work space is a great idea.

Since the Phillips screws holding the battery terminal in place are different lengths, I marked the head of one with a felt marker (Vital advice from the 5-S battery swap)

The fellow suggesting to pry the outer edge of the battery loose before unscrewing the terminal had a good idea.

The tweezers from a Swiss army knife is adequate to remove, manipulate and re-install the gold tipped ground clip.

A toothpick for alignment of the jittery and jumping gold-tip ground clip is very helpful.

Lucky I had no re-connection issues.

I was so nervous to start after all the youtube video and read-through prep that I forgot to power down the phone. Lucky that had no impact.

I bought the battery replacement kit and everything went almost smoothly. I just got the screws mentioned in step 4 mixed up. They are both really small but they are not the same size. I should have kept better track of them. The difference between the two are almost imperceptible. As suggested by others, a pair of tweezers and a white towel was really helpful.

I did it without any problem. You just have to really pay attention to how things are set up and be careful not to touch parts that are not involved in the replacement. The pressure contact underneath the top screw of the battery connector will come loose while prying the battery connector from its socket so you'd better remove it entirely and put it back in place after you've clipped on the new battery's connector. Was full of doubts and fear that I'd damage the phone before I started but I m happy I went on and did it by myself cause it's not worth the 60 euros one has to pay for the replacement! Get the tools and use them for all your repairs instead! Thanks for the guide folks!

Thank you IFIXIT. 4S battery replacement went well and took just 10 min. Network provider manually selected. Fitted the ground piece with the help of a toothpick ;-)

Very disappointed. The battery plug to the pc board was not the same as the original so I could not complete the install. Reinstalled original battery and now I can NOT power up the phone unless connected to an external source. After that its OK. Waste of time and waste of money. Now I cant power up if I don't have a power cord like after getting off an airplane. If Ifix it reads this you can contact me at chrislaletin "at" mac "dot" com

I tried today as my old battery didn't perform any more. The replacement went like a charm, done in 5 minutes. After booting and entering the SIM code, the network was not found. I plugged it to iTunes, rebooted while plugged in and then all started work as it should. Thanks for the great guide!

I bought the battery replacement kit a few weeks ago, and made the replacement today. But I had to put the old battery again, as the " new" one did not give any result : the phone was acting as without battery (was only able to put it on when connected to a charger or a computer). It is not an issue with the replacement procedure, as the guide is clear, and I had no trouble having my phone working again with the old battery (and I tried twice with the new one).

Can the battery I received be malfunctionning ? (using a multimeter, I see a voltage bias of 3V approx. between some of the pins, so it is not totally dead)

Any other idea at what might be the problem ?

easy breezy lemon squeezy :). changed the battery no glitch. Even though i am not very good with these kind of things, the step by step guide made it really simple. Thankyou.

I thought iphone is so sophisticated and changing battery will be a pain in the @%^, it turned out so easy following the picture instructions. Great! Thanks a lot!

Actually ordered the battery because it was time and because there was a rattling sound in my 4s.

I did some researching and saw that it could be the lock/power button screw. I opened up the phone and saw a screw sitting in the top corner of the phone. I took it out but didn't replace this as I wasn't up for a major teardown. I just didn't want to short something out. Anyway, the whole thing took 10 minutes and the phillips screwdriver from the liberation kit fit all the screws inside. Not mentioned anywhere but everything was there w/o any synch/restore afterwards.

It's actually easier than the guide would lead you to believe! Thank you iFixit!

Easy peasy, lemon squeezy. For $24, buy this kit and fix the battery yourself. The kit showed up at my house within 3 days of ordering it (from CA to the east coast) and the instructions couldn't be simpler. Included in the package is a liberation kit, which replaces the screws so that special tools are not needed to fix the phone in the future. Overall, a great purchase. This probably saved me close to $100 with quality parts and easy instructions.

can anyone tell me what happens if the ground contact is not reinstalled. Like so many others of you, the screws on my phone were stripped by the screwdriver provided, and the ground contact had been left out

Excellent guide. I'd bought the iPhone toolkit, which is absolutely essential. The screws are so tiny I placed them on a strip of sticky tape, carefully labelled, so they wouldn't get lost. The best news is the new battery worked. Like someone earlier I had to restart the iPhone for it to recognise my phone network. I used iBackupbot to find that my old battery's full capacity had become 900 mAh after 343 charge cycles. That's just 63% of the design capacity. Not good. I also found lots of online stores selling cheap iPhone replacement batteries. Feedback from many customers indicates these are used batteries (lots of charge cycles!) and should be avoided like the plague.

I am so thankful to ifixit for boldly going where no on has gone before on these procedures, greatly appreciated! I followed the steps and all seems to work well. that ground wire referred to did not seem to move in mine and stayed in place when i removed the battery connector. There was no adhesive left to use on new battery so i just put it in and the case seems to hold in place tightly nothing loose when I move it around. And I did use a dab of 91% alcohol on any of the metal of battery connector i touched and also the inside back of the case which looked like it has some fingerprints and not sure if that metal is part of the antenna system. And yes the slightly magnetized screwdrivers work great to position the screws! The battery had a 47% charge and seems to be charging nicely right now. Crossing fingers!

It took about 5 minutes :D

I had The "Searching" Issue. I gave it ten minutes and nothing. So I reset the network settings via Settings>General>Reset>Reset Network Settings and the problem persisted. However plugging it into my PC seemed to work and it found the network (thank god since this is my work phone). However I do have the problem of the phone resetting itself every minute (quite literally, every minute). I don't know what this could be I've taken another look inside but nothing looks out of the ordinary. Any help would be appreciated.

This kit worked great. The battery swap took a total of 4 minutes. The internal screws that need to be removed are ridiculously small, so it was great to have the magnetic tipped screwdrivers! They makes all of the difference for an easy peasy installation.

The tools are right and the install was flawless, minus the tediousness of putting the ground clip back, but it's all part of the game. I didn't bother with the replacement screws which wasn't an issue.

If mobile network doesn't work remember to set up right date and time, and after this to reboot device!!!

Hi, I changed today for a new battery. It took me about 1 hour. You need good light and very good eyes or a magnifyer.

My most difficult part was getting the tiny black switch under the metal and fix both with the tiny screw. Fortunately the supplied screwdriver had a magnetic tip.

after replace my batteries on iphone 4s with guide from ifixit

when im turn iphone on , i've got no signal

i dont know whats wrong

im carefully follow the guide step by step, i not go to any step further before make sure that my step is exactly same as ifixit explained

im googling over and over to know what make my iphone no signal after replacing battery

and then finnaly i found it

thats becouse every iphone 4s that have changed the battery , the setting time and date are roll back to jan 1900. thats why iphone cannot get any signal from provider

after setting time and date back to the future.. voilaaaa my signal is back

conclusion is. if you guys get problem with no signal after replace battery. go check your time setting.

thats my story. sorry for bad english

I give the product an A (so far; it has just reached 93% charge after starting at 50 an hour or so ago, but it seems to be fine), but the instructions above a C at best (I think I am being a pushover; a real teacher would make it a C- or D+). The only difficult part (really the only part that is not obvious) is the tiny connector (black on one side, gold colored on the other), which falls out and then one has to look at the comments, and then look further on the Internet, to figure out what to do with it. Really, not to even mention this critical item (with its critical orientation), and/or show a picture of it even, is bizarre. Why?????

So kudos for making it possible, but please rectify this omission!

That was super easy

I just did it for the second time - and it took me only a few seconds! Okay - to be honest a few minutes.

It's much easier than one might think.

You just have to lose the fear of the apple! It´s not poisoned!

Easy. Did need tweezers for the little ground clip. A better detail shot of that in the guide would be helpful. Most pleasing was having ordered late Friday night and selecting standard USPS shipping to Iowa, battery arrived Monday three day ahead of schedule. Thanks.

iPhone 4s Battery Kit = AWESOME!

I'm a computer tech but have never really worked on phones... Read through the instructions (with pictures) on the ifixit website and decided I would give it a shot and I'm glad I did because it was stupid simple and straightforward!

Thanks ifixit!

To install the battery it is not true that you do exactly the reverse.

One thing I struggled with was getting the battery connector back on. The trick I saw later on a video was to:

- First attach the connector, and after that

- Place the battery in the phone

The advantage of this is that the flat cable does not "work against" the connector when trying to click it back on. Would have saved me quiet some time.

Worked perfectly. iFixit: Really great job on the guide ... the parts ... and the tools. I like how iFixit provided replacement phillips head screws to replace the pentalope screws. When you have it back together, a hard reset does the trick to bring back cellular signal. I also did network reset for good measure.

Good guide but left out that it is hard to put the back of the phone back on after the new battery was put in. But beside that it was a quick and easy repair.

Kit worked great. My old eyes were at about their limit with those tiny screws but it all went good. The biggest issue I had was the battery was really stuck down and took a lot of playing to get it loose.

Great instructions

I have just replaced the battery for my phone today. It works well.

If there is a "no signal" problem, just go to Setting -> General -> Reset -> Reset network

Thank IFIXIT. :D

Received it quickly and perfet. Super easy to change, took me top 15min. No problem at all after 48h. Thanks iFixit

well done, took me 5 minutes. thanks!!!

I just changed the battery on my 4s, but it is stuck on the apple logo on start up. Any suggestions?

I'v replace my Battery in Iphone 4S now it will not charge in the car what did I do wrong?

can any one help

Stan

I have changed my battery, now when I charge it every couple of minutes it vibrates and comes up with the apple start up sign, also when it gets to 100% charged it doesn't count backwards to 1% so have no idea how much charge is left and then it turns off when if runs our of charge? Any ideas how to fix this problem please?

If you are getting issues with your cellular service no connecting, follow these steps.

1) Turn off the phone.

2) Remove SIM card using tool.

3) Replace SIM card (just slides back in)

4) Turn phone back on.

If problem persists, try a hard reset. Then from there try a restore.

Anything past that is most likely a hardware issue. You may have broken a cable or damaged the board in some way.

Very Useful Instruction with good pics.I Followed the steps and replaced the Battery within 10 min. Thanks!

that i want to know that How Much is the replacement batter thanks

Ok, I thought, I'm up for a challenge to change my 4s battery. It was harder than I thought. The tutorial and comments were helpful but it took me forever to get the screws back in the silver plate! After some time and frustration I figured out you need to " click" it back in! Once I got that the little gold thingy slipped right under the plate and voila! I got the screws in. Now I've done it once it should be easy next time! Word of warning; keep light pressure when handling screws until it gets matched with hole they kept flying off. Recommend putting white sheet/towel on floor way easier to find that way.

Awesome instructions! I fixed my girlfriend's phone in a manner of minutes.

If your signal says "Searching..." do not panic! Just go to settings->general->reset->reset network settings. That fixed it for me. If that doesn't help, maybe then start to panic.

IPhone 4s Battery Replacement worked fine, Documentation that describes the steps is good. The Phillips screwdriver that came aus Part of the Kit does not fit to anything, not to the 2 screws in the iphone and not to the liberation screws.

iPhone 4s battery replacement worked fine. The Phillips screwdriver that comes as part of the kit does not fit, not to the liberation screws and not to the 2 screws within the iPhone.

The instructions were clear and easily followed. Thanks.

Thanks heaps. The instructions were spot on. Job completed in about 15 mins.

Hi. I've just changed the battery over yet when I turn my phone (4s) on the apple sign comes up , then disappears then comes on again. Tried holding on/ off buttons down for 10 seconds but nothing changed ? Any ideas please

Be patient working the battery free from adhesive. Take extra time prying from right side til adhesive is truly free. All else was smooth. Worked great.

Take extra time to fully release adhesive by prying on right side of battery before you pull on tab. All else quick and smooth.

The battery is attached to the battery connector by a black band that for me did not fold into place easily. It required some fiddling but eventually went in place. Also, jeweler' pickups were useful in placing the pressure tab (gold contact up) under the top screw of the battery connector which then seemed to go into place after the screw was tightened. 10/8/2016

Thanks again - about 8 minutes to complete - 1 problem the Phillips screw driver sent in the kit was too big for the screws holding the battery tab, but this was not a real problem as I have a selection of Phillips screw drivers of the proper size.

The other 5-point screw driver fit just fine.

Nice one. Thanks. Worked well for me...

When I rebooted it seemed first like problems with the GSM data. Voice Call and 3G data worked fine. After another reboot and a few minutes it's all good now. Charging now and hoping for battery life improvement over my 5 yr old battery.

Just finished using this kit - some notes for all:

1 - Tools - I did NOT use the Phillips tool with the kit after reading several comments about stripping the incredibly small screws, I used the smallest standard screwdriver I had in a jeweller set that I already have. Note that these 2 screws are VERY small, and can tend to drop back into the body when re-assemembling. A set of tweezers is very helpful, both with this and the grounding clip. Shaking out the screw driver on the top had to be done several times, along with resetting the ground clip - this really seems to be the hardest part.

2 - PLEASE look at the video from HighTechDad re: the grounding clip!!! It readily points out how this part can (and will) pop off when removing the battery connector. Watch the video FIRST to see how the clip is oriented, and tweezers are very good to use here.

I had a magnifying glass handy, just to get a good look at the connector after getting it apart.

THANKS IFixit!

I have just replaced the battery on my Apple 4S using the IFixit kit. All seemed to go well until I switched it back on. The charge on the new replacement battery was about 56% and I was getting a good wi-fi signal. However, I could not open the phone as a warning screen appeared stating Temperature - "IPhone needs to cool down before you can use it" I have tried a hard reset and also taken the sim card in and out but to no avail. I charged the battery up to 100% and tried again but still with the same temperature warning. I don't know what else to do. Does anyone have any ideas?

I have the same Temperature - "IPhone needs to cool down before you can use it" error. I believe this is a problem with the new battery. If I put the original battery back in, the iPhone works fine. If I put in another new battery that I have (also from iFixIt), the iPhone works fine. Just one of my new batteries exhibits this problem. I've contacted iFixIt for a replacement. Still waiting to hear back from them.

tengo una duda , al parecer luego de hacer el cambio de batería el teléfono funciono bien durante unas 4 horas aproximadamente de un uso bajo , el problema es que al descargarse el dispositivo se apago y hasta el momento no ha vuelto a encender , algún consejo o sugerencia me seria muy útil , gracias .

Tolle Anleitung - echt Klasse vor allem mit eurem Werkzeug.

Austausch des Akkus hat ohne Probleme super geklappt .

Written steps were very clear, pressure plate popped out, but was replaced easily. I actually put the screw in to secure the pressure plate before I completely seated the battery, because getting the battery in was getting the tiny plate out of alignment. Used previous suggestion to put in airplane mode before shutting down and both wifi and phone came up right away. I'm 61, wearing glasses under bright light, and it went pretty smoothly.

It took me all of about 5 min from start to finish after watching the video phone fixed I was amazed how easy it was and I'm an old fart

Perfect instructions. Finally my wife's phone has a new battery. She is so happy.

After the replasement my Apple charger doesn´t charge properly. When I plug it in over the night, it seams to charge but in the morning the battery is emtpy.

Does some knows why? Does the Apple charger see if the battery is not a original part?

Thx for help

My battery install went smoothly. Took my time and followed the directions step-by-step. Took about 40 minutes. Phone booted right up.

My battery install went well. I followed the directions step-by-step. Had problems folding the battery connecting wire so that it would not stick up and interfere with the closing of the top. Also the small grounding clip was a pain. Took about 35 minutes and it booted right up after doing the "Hard Reset" Phone works fine. Thank you Ifixit. Charging now.

Had no signal. Took cover off and flexed up the ground tab and cleaned the back of the cover and the connector with alcohol and signal then found.

AWESOME. It was really 10 minute repair. Easy to take the cover off, and it was easy to take the battery out. The battery temperature is at 25 degC. The only hard part was slipping the cover back on.

When I finally got one screw started in the battery connector, the head of the screw sheared off. Was ready to toss the phone but managed to remove the threaded part of that screw and used super glue instead of any screws on the connector and re-assembled. Phone works.

My install went well. However, my kit did not include the plastic pry bar. I had to improvise but I was careful and the battery swap was easily completed.

One suggestion I have is to lay the battery on the phone and make up the connector before trying to fit the battery back inside the phone. Much much easier than having to fight to bend the battery wire/connector while screwing in those tiny screws.

Just replaced the 4s battery in our phone we use for streaming music. Battery out was mfg'd 03/2012. All went smoothly. Discharging new battery for the "conditioning part. Picked up the kit at Fry's for $20. Now to do the same for Mom's same iPhone4s. Thanks for the instructions and video.

iam change the battery to my iphone 6s plus

Was a little leary about opening up my phone, but am tired of not using the phone for fear the battery would go dead. screw driver tips that came with my kit were'nt the best, but with some others I had I got the job done. Was kind of fun and exciting! Now I'm running the new battery down to recharge it. Thanks for the great instructions! Also the video !

This was as easy as it looked in the video.

Repair was quick and easy as stated. Unfortunately in Australia, I cannot buy an ifixit battery, and purchased instead a cheap eBay battery, which is much better than my original, but no miracle performance. Also, it made my phone turn off and not on again, fixed by reconnecting and disconnecting again. The old beast lives on to fight another day, and the charge lasts until evening with light-moderate use.

I stripped one of the screws holding the battery connector. Project over.

It took me about 15mins to replace the battery. I forgot to turn of the phone.

After the phone wouldn't switch on so I plugged in the charger and on it came with 38% battery.

It was easy, as the instructions were good. Thank you I had a great time doing this.

I had bought the basic tool kit and some little tools came with the Battery, but, I wish the basic tool kit came in a box, it's a real hassle keeping the little bits in safe place to use again.

Hi, 7 months back my Father replaced Iphone 4s battery. But when update the phone, it showing error like Unknown error occurred and error cord is 29. I searched and got the solution. Replace the battery with OEM. Please let me know is it original OEM battery for iphone 4s?

Used the iFixit iPhone 4s battery replacement kit with all the proper tools for the job. Read the instructions, looked through people's comments, watched the video, placed my iPhone in flight mode before switching it off, and then replaced my old battery with a new one. I did not want to unnecessarily damage my only phone, so I took the time to educate myself in the little things that could go wrong and how to do it right. There were some great tips in the comments. Phone working fine and looking forward to a renewed battery life. It is a really great feeling to fix things myself, so BIG thanks to iFixit team for all the support.

Just replaced the battery on my Iphone 4S using the Ifixit kit and battery. Much like the previous comment I did my research, watched the videos and read the comments. It was a little tricky getting the two screw back on the pressure contact plate but with a little patience it was do able. Ifixit rocks!

By slowly following the guide and watching the video, I had a very easy time removing and replacing the battery on the iPhone 4. I would recommend the magnetic pad or laying a strip of tape down to put your screws on and have a very uncluttered work area in case a screw gets away. As the video and instructions say, pay very close attention to the pressure plate position when you are removing the battery connector screws. Placing the connector back down is a little tricky, you need to work with the connector to push the connector in place. I put the top screw in first, then the second. Good Luck....

Perfect., Awesome & Quick..... plus by using the ifixit deluxe tool kit everything always go's smoothly! I like my 4S phone & will only replace it once it completely dies. Thank you!

I did it! Hoorah! It only took two try's for this 72 year old grandmother to change the battery. WOW! Thanks for the video and the guide. I followed it to the 'T'! I am so happy that I don't have to get a new phone! Thanks again.

The guide is very concise & complete. Although I have not attempted anything like this before, I was able to complete the battery replacement quickly & easily. The tool kit is well designed with the screwdriver heads placed in order of use. I will definitely recommend the site, guides, & materials.

I am 82 years young and I managed to do the task with no problems, and I have just ordered another battery for my wife’s iPhone. the tutorial was good to follow, although it is wise to read comments to avoid pitfalls. Putting the phone on “Airplane Mode” prior to booting down is a good idea, although I went one further and took out the sin card as well. After completion, booted up, in sim card, “Airplane mode” off, and hey presto, everything as was b4 I started, except for having a replacement battery, which I hope will be worthwhile.

Lino Scicluna. November 5th 2017

I have just received the second battery to put in my wife’s 4S as stated in the above post.  Because I now had more confidence, I managed to do the task in just over 10 minutes. I cannot understand how quite a few reviewers had a few problems, mainly with the phone not working properly afterwards, without using iTunes, hard resets, etc. the trick to avoid this, which I believe is not mentioned in the tutorial, is to put the phone on “airplane mode” b4 powering down, and it may help to take the sim card out after that, which I did, reversing the order on powering up. One thing I forgot to mention is, that I prised the battery away from the adhesive pads prior to unscrewing the battery. the only thing I have to worry about now, is that the new batteries prove their worth after the obligatory treble discharge/charge.

Iphone 4S battery change, reviewed the video first , then took my time with good lighting, battery was miserable to get out but all went very well. Followed instructions and did hard boot right away, worked perfect. Could tell right away, took a long time to run the battery down to 10 % so I could recharge it to 100%. Use to die after 5 mins of video, now it stays for hours. Awesome battery, thanks and great instructions.

I got through it ok, but they need to provide better instructions on the pressure sensor. It will certainly pop off, and if it’s not reinstalled in the proper position, I imagine you’ll have trouble and never know it.

I just checked— No it won’t update beyond 9.3.5

I just completed the iPhone 4S battery replacement. The original battery was dead, so I plugged in the phone and when the battery reached 10% charge, I unplugged and went to Airplane Mode, turned off Wi-Fi and Cellular. I then started disassembly. The pentalobe screws came out easily and I pushed up on the back of the phone and pulled it off. The two screws securing the battery were stuck, but with a little more pressure I loosened both screws. That took an extra 10 minutes being careful not to strip them. I did not realize that plate was attached to the battery, but figured that out quickly when prying the battery away from the adhesive underneath. The gold/black piece popped off, but I was able to return it to it’s original position. With the new battery in I was careful not to touch the plate that attaches using the two screws with my finger. After reinstalling the back cover and screwing in the two pentalobes, I let the phone charge go from 56% to less than 10% and then charged to 100%. No problems!

I’ve completed the battery replacement and the phone has booted up. Just one thing: it’s not clear whether the pressure contact fits over or under the battery connector. I fitted it under and it seems to work. Boy do you need little fingers and sharp eyes!

Oh, I couldn’t detect any difference between the two connector screws…

Just changed battery on sisters 4S. Thanks to the many great comments and suggestions the change went smoothly and startup was flawless.

Boy are these screws tiny..!!

Tips that helped include: using #000 Phillips, working on white towel, egg cartoon parts holder, project light, iPhone magnifier on my 6S, toothpick to hold the two clips in place until I started the small lower screw, magnetized the screw drivers and tweezers, and plastic gloves to avoid contamination.

I still managed to dump the grounding clip onto the floor at one point but luckily found it.

Without the detailed procedures, photos and comments I would never have attempted this.

Thanks to all.

Ordered that Fixit Kit 2 weeks ago and just replaced the battery which took about 10 minutes, everything worked as intended but i used a magnifying tech google i use normally for soldering to place that tiny antenna pressure contact and those tiny screws back in place. Oh and i also cleaned that plate with acetone before putting the back plate back. The Device came back up without any issues with 56% Battery and i now deplete it to fully charge then.

I replaced the battery, but something was not quite right. When the battery was below 10% I plugged it in to charge, at which point the phone began rebooting every couple of minutes. After about half an hour it stopped rebooting, at which point I was able to use the phone. It worked all day, although the phone showed 67% the whole time. The next day the battery was flat. I plugged in the phone to charge it, but this time the boot process only got as far as showing the Apple logo before rebooting. I tried entering DFU mode and reinstalling the software via iTunes, but this failed with error code 29. The phone is currently unusable. Suggestions much appreciated!

I replaced the battery but the phone is rebooting continuously. I tried resetting it per the instructions several times but this has not helped. Any suggestions would be appreciated. Thank you.

I repeated the procedure and this time it’s working! Yeah! I checked two things that might have made a difference - 1) that the four copper contacts on the battery connector were touching the four contacts on the part beneath it; and 2) that transparent plastic pull tab from on top of the battery had folded over the wrong way when I closed it the first time, possibly stopping a connection from occurring, so I flipped it back the other way to ensure that it was resting on top of the battery when I closed it this time. On a side note, the new battery is a lot better and the phone is a little faster, but still slow compared to a new phone.

Battery wouldn’t work. Tried to restore iphone through itunes and it gave an “ERROR 21” message. Looked it up and found this error indicates battery is not compatible. Re- installed old battery and restored and phone works fine.

Thanks a lot. It was my first iPhone opening and the repair took me ca. 8 minutes only. 4S works much better now. Best Regards, Robert

Any idea were I can find the gold and black piece that acts a ground for the battery?

Bonjour ifixit est le roi des pièces détaches et le seul vrai qui vent de la bonne qualité je vous recommande a vous tous chers usager même les outil sont de haute qualité les photos sont 100% originales merci beaucoup cher ifixit Germany :)

Just completed the swap, a very simple task. It took less than five minutes… but thats probably because I spent twenty minutes studying the procedure and reading the comments!

Thank you iFixit peeps, and contributors.

I do wish that the video continued to show installation. Getting the battery out feels like only half the challenge. I would have liked to see some helpful techniques on how to line up the contact board so the screw holes align. I got it though!

In addition to Steps 1 to 9 for switching out the battery, there is a Step 0, which is read all 200-plus comments posted since 2012. Some might be applicable to you, depending on the particular iPhone 4s you have.

Reassembling is NOT exactly the reverse order of disassembling because you need to snap the battery connector into place before putting the new battery into the case.

Also, the black-gold pressure contact thingy was tricky to put back into place, under the battery connector.

This was an excellent guide. Was able to replace the battery in under 10 minutes. The most difficult part was removing the battery from the adhesive.

Worked like a charm!

Follow the instructions. Use the proper tools. Take your time. You will have no problems.

I should have done this a long, long time ago!

Thanks!

Sehr hilfreiche Anleitung, gute Bebilderung und nützliche Tips. Der Akku-Austausch ist vollbracht. Mal schauen, wie sich die Batterie-Performance so entwickelt. Bin optimistisch.

1 kleiner Mangel am Tool-Kit: Das mitgelieferte Kreuzschlitz #000 - Bit war unbrauchbar (viel zu grob) und hätte die Reparatur beinahe vorzeitig torpediert - glücklicherweise hatte ich noch einen passenden Uhrmacherschraubendreher vom Opa zur Hand - also ging es noch einmal gut :-)

Ansonsten alles sehr erfreulich: von Werkzeugen, Ersatzakku, Verpackung , Lieferung bis Anleitung! Gerne wieder.

Very helpful & without it being so easy to follow I would have done A LOT of damage.

Thankyou 10/10.

Just followed this guide to replace a swollen battery. Removing the battery was the hardest and most nervewracking part…. I was nervous about removal… went slowly and used a credit card under the battery and along the edge to get glue to give. New one connector cable needed to be “shaped” to get it to connect. Take it slow, be careful w screws and get it done. I recovered an important sound file of an interview from the Iphone 4S I use for interviews (w a TASCAM mic). Thanks I-Fix it! Did it all outside as I was nervous about the battery… which swelled pretty dramatically when I was charging the phone (just heard cracking and went back to check on it…) Safety glasses, a bucket of sand…. can’t be too careful. The phone lives to fight another day and record a few more interviews!

While trying to reconnect the battery connector, I found it much easier to do it with battery sitting on the case. After tightening the connector screws, I started the left side (connector side) of the battery into its slot, carefully tucking the ribbon between the battery and pocket, and then pressed the opposite side down.

Reparaturanleitung war sehr hilfreich. Danke!

I pushed new life into this phone until I can't get used to not having to plug it into the charger.... Only so what, almost everywhere the operators turn off 3G..
