iPhone 4S Mobilfunkantenne ersetzen

my screws are stipped and i am going though the front glass to get to the logic board could some one give me a guide on how to get to the board please... thanks

all you need to do is remove the clip over the wifi antenna and the one that actually attaches the wifi antenna to the iphone two steps to do this job...

I didn’t find this particularly difficult, even though I’m pretty inexperienced at this sort of work. I watched the video overview to get me going and then followed the steps in the guide. My tips would be to keep the screws and parts organised as you dismantle, and ensure you read all the reassembly tips as you go; it’s easy to skip over them. I also found using the Liberty Kit to replace the pentalobe screws was worthwhile.

Poor old Marv of Feb 2015. Suggest he sticks to chopping logs.

caught fire as soon as I replaced the back phone destroyed

The battery on the phone is swollen so I need to replace it but I can’t turn it on to drain the battery, what do I do?

I pried one end of the back off only to find 2 funny little screws holding the other end on so I took my Dremel, like Jack said, and ground those suckers out. Once I had the back off I loosened all the screws then turned it upside down and shook the crap out of it. The screws went flying everywhere and fell on the floor. Its my moms house so of course she's got gross brown carpet. How am I supposed to find my screws in that? I get the vacuum out and go over every inch of the floor to suck up all them screws. Then I dump the bag on the table and all I find is a bunch of hair and gods knows what else, but no screws. When I look for my phone I see its covered in all that stuff that came out of the vacuum. I mean, what's up with that? How can I work on my phone if its covered in dirt? Nobody said anything about that, did they? The average guy's gonna screw up his phone big time if he follows these instructions and nobody warns him about all the dirt that's gonna end up in his phone. Are you kidding me!! Now what?

I didn't see any extra screws holding the back in place. I had to use the included pry tool to get the back off. Just start at the bottom and pry gently...if you just "pull" like the guide says it won't work.

Don't use too much force to slide the back -- the back on my phone was hard to slide, and I bent and broke a silver metal contact tab at the top of the back (on the inside).

Super easy fix. Thanks for the tutorial!

Those little screwdrivers are easy to mix up, for those of us without ultra-perfect vision! Once I used the correct screwdriver, and my 13yo son's little fingers and perfect eyes, it went smoothly! Also my son noticed that the rubber piece around the camera len was covering the camera; it likely slid out of place when sliding off the back cover. A little playing around (with plastic tools only!) and it looks perfect now!

sorry but the rear panel is not pushed up. I pulled out the screws in the step 1 but still the rear panel does not move with even when I push it strongly.

I too tried to push and slide the rear cover without success. I then tried just pushing the bottom edge up with my thumbnails. It moved very easily forward. Just a few mm movement is needed and then the cover can be removed.

The finger friction approach did not work for me, even when using a sticky pad.

Here is what worked for me: Grab the iPhone in your right hand with the screen facing your hand and the top facing your body. Find a sharp edge of a desk or counter and place the bottom of the phone's back cover on is so that when you push it, the back cover remans against the desk with the body of the phone sliding free. BE GENTLE as this approach takes far less force than the finger friction approach.

From this point go to step ?? Just peel off the tape from the chip. Take some aluminium foil and cut a hole the size of the chip (Use a second layer of foil if you don't thrust it). Heat the chip as described at temperature 300 deg C for 5 minutes. Let it cool down. Reassemble and ..... hura WIFI is on again.

In french: attention avant de retirer le contacteur de la batterie. La vis du haut tient "en sandwich" une petite pièce métallique noire et dorée. Cette pièce a pour but de faire contact de masse avec le dos de l'iphone quand il est refermé. Donc il ne faut pas la tordre. Quand les deux vis du contacteur sont retirée, attention au moment de débrancher le contacteur: cela va faire bouger cette pièce qui ne doit pas être abîmée ni tordue. Au remontage, il faut bien la remettre en place sous le contacteur de batterie: il est tout à fait possible de mettre d'abord le contacteur, puis de glisser la petite pièce au dessous pour qu'elle soit bien à sa place, le trou en face du trou de vis et du trou du contacteur. En remettant la vis, la pièce tient bien en place. Elle doit bien continuer à dépasser de manière a faire contact avec le dos de l'iphone.

When reassembling, use EST tweezers to get align the pressure contact over the top screw hole. using the pointy end of a spudger to assist: put the point through top screw-hole on the battery connector, then through the pressure contact and into the screw-hole. this will help to keep the small piece in place while re-seating the battery connector. Leave the top hole spiked as such until the screw in the bottom hole is gently fastened. Remove the spudger and replace the top screw.

Pressure contact needs to be remain EXACTLY in the same position if you remove/replace battery. I had to re-open my iPhone 4S after a battery replacement (the mobile connectivity was lost) and tweak the position of the Pressure to restore functionality.

I used my 16x magnifier loupe to be certain I had the pressure sensor aligned with the screw hole - no problem, no stripping. I consider it indispensable for tricky steps like this, and IFixit sells a similar tool for just $14.

The pressure connector is the battery connector under the silver plate. BE CAREFUL. It seems like it'd be really easy to tear that pressure connector out without meaning to. The bronze and black thing is the ground, *not* the pressure connector. If you remove it just keep track of it and re-install it.

The phillips head screwdriver provided in the ifixit repair kit does not work well this these two screws after my first attempt at unscrewing the screws became stripped. The 1.7 mm phillips screw gave me the most trouble. It took an hour to unscrew after the screwdriver from the kit stripped the screw. I used a piece of masking tape over the screw for grip to loosen it, then used finger nail clippers as pliers to unscrew. I would recommend investing in a better screwdriver for this one step. Assembly is otherwise simple and easy.

Here's a tip if you're having trouble removing the 1.7 mm screw. I had real problems removing it – the 1.5 mm screw came out easily using a Phillips #000 screwdriver but I almost stripped the 1.7 mm screw using the same screwdriver. What I did instead was use a flathead screwdriver from the iFixit pro tech toolkit I got, the one with a "–" sign and 1.0 size. That worked perfectly!

When disconnecting the battery make sure to use a plastic tool not a metal tool that could short out the battery

I would agree that a decent magnifier would help as the screws and components are small.

Also take necessary precautions to ensure the screws are not lost or mixed up.

Other than being a bit fiddly (particularly the earth connector), the only challenge I had not covered was that the battery was fixed with glue close to where the connector is and despite releasing the battery along the side, I couldn't get the battery to lift out using the tab. In the end I had to use the plastic tools to gently lever the battery away, working from the outside edge and ensuring I wasn't levering against the volume control buttons.

The new battery is in and following the advise given, I hard reset the phone and all my usual functions are now running... and if this £18:00 fix gives the phone another year or two of use, it will be well worth the effort.

Vous dites "Le connecteur de batterie s'enlève verticalement de la carte mère. Ne forcez pas latéralement"

Ou placez vous la verticalité ? pour moi c'est connecteur d'alimentation en bas, bouton d'alimentation en haut ?

Parce ce que sur la photo suivante, vous enlevez le connecteur de la gauche vers la droite ... c'est à dire latéralement ...

Soit nous n'avons pas le même sens vertical / horizontal, soit il y a un GROS problème dans l'explication, ou dans la traduction.

En tout cas, à la lecture de votre explication, j'ai essayé d'enlever le connecteur vers le haut !!

Donc il m'est maintenant impossible de remettre la batterie neuve, le connecteur est cassé !!!

Bravo pour l'expertise ifixit :(

I've gone through this process twice now. I found this video also very helpful: https://www.youtube.com/watch?v=nYYdbk3U...

The little contact thing that sits under top screw is always the biggest hassle to fit back into place (I do it after attaching the battery cable) with tweezers from ifixit.

My personal tips:

- plan that the incredibly tiny screws or the top-screw contact thing, might get away from you. so work in a space where you can find them easily. Not over carpet, etc.

- I use strips of tape on a piece of paper to secure the screws while they are out, and position them so I know which one goes on top of battery connector, and the one on bottom.

- If you have access to a spouse's/mate's iphone, in Accessibility settings there's a Magnifier option (triple-click home button) which does an amazing job at magnifying stuff at a circa 4-6" distance. Lacking any good magnifying glasses, this feature helped a lot. https://www.imore.com/how-use-magnifier-...

Why the guide don't mention PH000 or PH00 instead of Phillip 1.7 mm / 1.5 mm? I didn't know it is PH000 until some comments here save my time. Thanks guys

I wonder if the two screws shown on the picture are not inverted. It would seem logical to me that the longest (1.7mm) screw be placed on the upper hole, (where there is the yellow circle) ie on the hole where there is extra thickness (of the gold plated grounding contact sheet metal) in the sandwich. I have not checked, however, I just put the screws in the same location as found.

I was able to remove the screws without problem, but almost stripped one of the screws when reinstalling the battery connector. Be careful how much force you use!

It does not work

When removing the 1.7 mm Philips screw, on rare occasion, the socket it is threaded into, might come out with it. (It depends on how little of that blue glue was used underneath on the assembly line.) Grab the socket under the removed plate between your fingers and use your Phillips screwdriver to back out the 1.7 mm screw from the old shield. Then once separated, thread back in the socket, into the case where it came from. You will want to do that before installing the new battery. You will need a small flat blade to span the socket hole in order to thread it back in snug. When the 1.7 mm screw is threaded back in with the new shield (with the Phillips screwdriver), it should tighten the rest of the way. Don’t over tighten. Great little kit!

The black ground contact needs still more "flagging." This is a simple metal strip that is attached ONLY by the 1.5mm (upper) screw. It will help if you look at it before you remove the upper screw. Notice the gold contact arm and point. That contact point must be in a plane above every other surface inside the device when you replace the battery connector, because it makes a ground contact with the metallic inner surface of the device back plate.

When I replaced it, I used the Pentalobe driver to line up battery connector and ground contact with the screw socket post. I then attached the 1.7mm (lower) screw loosely, removed the Pentalobe driver gently, and inserted the 1.5mm (upper) screw into the assembly. There is a tab on the ground contact that helps it align properly once pressure begins to applied. I completed driving the upper screw, pressing lightly with the spudger on the battery connector plate to make sure it was seated on the pressure contacts. Finally, I completed driving the lower screw.

I didn't find any need to remove the pressure contact. I just pried the battery connector up (gently) with a spudger and left the pressure contact in place. Connected the new battery and aligned the pressure contact screw hole. Replaced the screws, finished reassembly and all was good.

After reassembly, the CELL CONNECTION WASN'T WORKING. You might need to slightly bend the contact in step 5 up just a little, so it will make contact with the metal back plate. Did that and it worked perfectly.

Great kit, great instructions, thanks!

all those teeny screws...and the world is so...well...BIG!

go slow and put those parts INTO something...

putting them "on" something will just cause heartache and and an infected bladder...

°¿°

after a lot of froofroo and very errant iphone behaviour problems, i concluded that that tiny grounding piece must be being lazy as hello. i spread it out a bit to ensure a better contact with the back plate and everything appears to be working smoothly.

did this repair, as well as the battery replacement...GTG!!!

spoke too soon, i 'spect...random reboots persist.

Just went through the replacement and the battery "plug" (step 5) on my replacement battery was slightly misaligned relative to the metal plate used to screw it onto the board. The plastic and "gold" "plug" was slightly askew on the metal plate, which meant that when the plug was inserted, the screw holes (step 4) were poorly aligned.

I managed to pull everything back into line using the screws, but the QC on these replacement batteries is a bit suspect.

Guess what happens when you rotate that ground connector 180 degrees...it grounds what I deduced to be the heat sink of the power amplifier for the speaker! So it is silent. It took me a couple of attempts to discover this as I was distracted by the new speaker not sitting down properly and a little dot of stuff under the main connector stuck to the pins. The latter was cleaned-off with a pin under 5x magnification followed by some isopropyl alcohol.

I suggest that Step 5 is more explicit about the orientation of this ground connector. It's only obvious after a really close look and if one has a lot to do like I did, it's a long time before one comes back to this step so the correct orientation is not obvious.

I accidentally removed the pressure contact and I was not able to put it back in place and so far haven't ran into any problems. Is this safe??

I did it als well. All Funktionen well.but i am Not sure if that reduce battery power? Thanks very much for information

The hole in the pressure contact aligns with the top screw. The IFIXIT tool kit I bought contained a black sharp “thing” that I used to align the pressure contact with the top screw hole. I used this tool to align the bottom screw hole also. I put the bottom screw in first but did not tighten it all the way. A good magnifying glass with a light helped a lot. Tim

Aligning with the black pointy “thing” definitely helps. Also, the small copper end of the contact piece is supposed to stick up once attached, to make contact with the back plate of the phone after re-assembly. The piece slides under the silver metal plate, and the the pointer can be used to align the silver plate hole and the black/copper plate hole in place for the screw.

What if you lose it?

Try a used plastic credit/gift card to apply gentle pressure to lift the battery out of the phone, the short edge of the card fits within the gap on the logic board side between the battery and video cables. You can also use it on the opposite side if there is room between the battery and iPhone frame. This has worked on all of the 4 and 4s models I've replaced screens on.

I offer an alternative image if interested.

Removing the battery wasn't necessary. I attempted the removal but decided not to in the end. It didn't get in the way at all.

I did not remove the battery to do a Speaker replacement and had no issues with getting the Speaker out/in. So, steps 4 and 5 are required but not step 6.

The plastic tab is not attached to the battery. I just pried from the right and slid tools under until I broke all the adhesive.

I found it easier to start by pulling the plastic lip to loosen the battery, then, if needed, use the plastic tool to pry from the side.

I tried to get the battery out as depicted in the first picture. It deformed and is now broken. Not happy. It seems better to leave it or get it out by gently pulling the tab.

Please, Please, PLEASE avoid using probing elements to try remove batteries. I have had dozens handed in to me with punctures and two that actually started smoking due to people trying to prise the battery out. DO NOT DO IT.

The best way I have found to remove the battery is this process;

1) Try remove it with the pull tab directly, some will come out, some will not. Do NOT use excessive pull force else it'll deform the battery and reduce the capacity.

2) If the pull test didn't work, then get a hot air gun on medium and warm up the area around the battery for about 30 seconds, focusing on the perimeter of the battery. If you see ANY popcorn'ing then you're too hot, you don't want to cook the battery.

2.1) Wait about 30 seconds for the heat to now wick underneath the battery to soften the adhesive.

2.2) Now try pull the battery up, the extra heat should have softened the glue that you can remove the battery without excessive force and without sticking objects under the battery.

Was having a hard time getting the screws back into the battery connector. Read another tip online that helped - pushed the end of my phillips screwdriver into some soft candle wax which gave it just enough stickyness to have the screw stay attached to the screwdriver while I was moving it toward the hole. Thought I'd pass that along.

I did as wazzamagu did (and stated above), "My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver." That made replacing the screws fairly easy. Thanks for all the advice on this page. It was not hard at all. Go slow and carefully, everything is smaller in there than I expected. The "searching" thing came up as it seems for most people, but just took a reboot and all is fine.

Instructions were good and everything works fine after replacement. Needed to use a tweezer on the pressure contact on the top screw of the battery. Thanks

I swapped out the battery today. No real issues. Pretty easy task.

For the past couple of months, my phone had been dying very fast. I knew that my phone's battery capacity was getting quite low as this phone is older now, and is out of warranty. So I ordered a replacement battery about a week ago, and just installed it yesterday. The install was pretty easy, if you pay attention to where everything belongs. But my draining issue has not gone away. It stays charged a bit longer, my capacity is at almost 100%, yet it can't even hold a charge over night. I'm not sure what is causing this and would love any tips or stories from someone else!! Please help!!

Beim Einbauen des neuen Akkus ist es sinnvoll diesen zuerst anzuschließen und dann erst wieder in die richtige Position zu bringen da man so dass Anschlusskabel besser verlegen kann

OMG thank you iFIXIT, the apple store wanted 3 times the cost of this repair kit. It took less than 5 minutes with most of the time spent trying to prise out the battery as it was glued in nice and tight but steady pressure from the spudger did the trick.

I think the best advice would be to touch nothing with your fingers as with careful use of the spudger I was able to position the tensioner point no problem. Everything else was nice 'n' easy.

Finally there was no cell connection only Wifi when I powered up so I simply powered down and up again and all is well in the world!

Thanks again.

Be VERY careful not to pull on the plastic tab before you fully detach the adhesive or else you will rip the tab clean off. If you did this it is still possible to remove the battery. I just used the guitar pick tool things to slowly work it through the adhesive and under the battery

It is possible to remove and replace the upper antenna WITHOUT removing the logic board!! So skip from step 7 to step 21 to 26 and 27.

Stuck on searching after unplugging and plugging in the battery?

This is due to the date and time being set back to default. To fix this you will need to synchronize the date and time back to what it is currently.

You can do this by either:

- Connecting the phone to either a Wi-Fi network, Cellular Network (Mobile Data).

- Connecting the phone to iTunes (It will synchronize the time automatically once iTunes is opened and can detect and access the iPhone).

Once the date and time is synced you will need to turn airplane mode off and one as it may display 'Searching... 3G' or if it still says searching (which most of the time happens if the sim card has a sim pin lock enabled on it) you will then need to turn the phone off and on.

Watched the video and ordered the kit, followed all the steps and it all went brilliantly - thank you all so much.

Is it suggested that I add more adhesive with the replacement battery?

One thing I noted with the replacement battery - from AussieBattery here in Australia; not from iFixit - but the same problem might occur; is that the cable on the new battery had to be 'tamed' (bent here & there like on the old battery, before I could reseat the screws and even the battery itself. One again the black - pointy & flat ended - spudgers, that we use in desktop iMacs, were helpful in getting under that battery and releasing it from sticky-!&&*! I used a pair of '2.5' reading glasses for this job, but '3.0' might have been better, as those screws are INFINITESIMALLY small!!!!! :(

Thank you IFIXIT! The battery replacement went very well for me. I was exceedingly careful with the minuscule fasteners. Reading through the instructions, watching the video and reading these comments before jumping in helped. I found the parts and tools to be of good quality. I feel like I beat the system! I used a pair of diopter 3 reading glasses which was a real aid. I hope my comment encourages others...

My rare earth magnets came in handy when I managed to lose the little grounding connecter screws. Those little guys will go flying if, while trying to align them for reassembly, pressure gets applied in just the wrong way. I say one fly out and bounce off my shirt, then it was gone, on the floor I presume. I grabbed my stack of 8 little magnets, waved it around on the floor under where I was sitting and what do you know? A little screw was stuck to it! I never would've found it just by looking...

You really need to include information about the pressure sensor. It WILL inevitably pop out, leaving us wondering how and in what order it should be replaced. I had to look elsewhere for videos outside of iFixit to figure this out. Also, tell us which screwdriver to use using the label on the bit (PH000, P2, Y000, etc.). Providing only the sizes of the screws does nothing to help determine the appropriate bit to use when they aren’t labeled as such. Otherwise thank you!

I replaced the battery and the phone started right up. But I cannot get it to charge It was half charged when it went in new and I plugged it into a charger Checked it later - not charged. So tried another charger and the green charging light still will not come on . Any suggestions? Thanks Don

I succeeded to replace the screen, but I made a mistake with the batterie cable, and it finally broke, seems that the cable was too long and I was forced to make too tight loop.

Maybe a series of photo to explain how to make this the right way.

yoooo that was so easy and fun man!!!!!! love y’all

January 21st, 2020. My original iPhone 4s battery finally kicked the bucket. I just finished installing the new battery with ifixit.com and their parts kit. $16.99 and 30 mins of my time and the phone lit back up and is currently doing the charge for calibration. Thanks so much ifixit!

I succeed without any trouble. Tools and guide are excellent! Thank you

Great instructions. Couple of things. If new battery comes with a removal tag make sure you remove the old tag, Step 7 could be clearer, the pressure connector just falls loose when you first remove the battery connector and its hard to work out how correctly realign.

Excellent product - and now for a glass of Australian Shiraz to celebrate

In this picture (actually in all of them) the cellular antenna cable is not routed properly (red line). Be sure when reassembling your iPhone 4s to route the cable around the metal finger (yellow line).
