iPhone 8 Battery Disconnection

Step 1

Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
Power off your iPhone before beginning disassembly.
Remove the two 3.5 mm pentalobe screws on the bottom edge of the iPhone.
Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

just how long are those screws- i turn and turn and turn and the lift off is soooo slight, seemingly insignificant…

I would recommend, from the very beginning, dumping all tools out of the kit (if you got it) and using that white paper tool box as a tray to organize the screws and braces in. It’s nice to work over because it catches screws well and makes it easy to see them if you drop any.

Johnny Emrica -

That’s a great idea thank you

Mohamed Dekkiche -

Screw to the left of the charging port will not come out. Screw on the right came out no problem. Any ideas?

Bill Maher -

Step 2

Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.

No hair dryer so GENTLY heated over stove burner

John Toth - 13/10/20

Hello,

What temperature is suitable for removing the front display ? I bought i-Fixit ProTech which is not include the heating "roller" . Thanks for help

Jiří Sítko - 28/01/21

Ich habe eine heiße Wärmflasche verwendet. Das hat gut funktioniert :-)

Moritz Hartges - 18/04/21

I laid my phone face-down on my 3D printer’s heated bed, and set the temperature to 60 C. After a few minutes, it was ready to loosen.

Nate B -

If you don’t have an “iOpener” or heat gun, try using an electric heating pad. I have a small $11 pad I got at CVS for my knee. On medium heat it worked fine for removal and with the “pennies” for setting the new seal.

Pete P -

I used a heated tea kettle and a tea towel, it worked!

Adam Yavner -

I put on the furnace vent for 10 minutes to get it warm to the touch but not hot.

terrelldoc -

I attached it to the after burner of my rocket ship and that worked.

Matt Brown -

I'm holding mine just above an erupting volcano but I'm still waiting to see if it has worked. How long does it need?

Paul Aron -

Step 3

The next two steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down two steps for an alternate method.
For complete instructions on how to use the Anti-Clamp, check out this guide.
Pull the blue handle towards the hinge to disengage opening mode.
Position the suction cups near the bottom edge of the iPhone just above the home button—one on the front, and one on the back.
Push down on the cups to apply suction to the desired area.
If you find that the surface of your device is too slippery for the Anti-Clamp to hold onto, you can use packing tape to create a grippier surface.

Step 4

Push the blue handle away from the hinge to engage opening mode.
Turn the handle clockwise until you see the cups start to stretch.
Make sure the suction cups remain aligned to each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.
Wait one minute to give the adhesive a chance to release and for the bottom of the screen to open.
Insert an opening pick under the screen when the Anti-Clamp creates a large enough gap.
If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle clockwise half a turn.
Don't crank more than a half a turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.
Skip the next two steps.

Step 5

Apply a suction cup to the lower half of the front panel, just above the home button.
Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.
If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Even with using high heat from a blow dryer, I had to put the suction cup over the home button or the bottom edge wouldn’t lift at all. That waterproof adhesive is incredibly strong.

Aaron Soderholm - 04/12/20

As others have said, this part really stinks, but it’ll work if you keep trying. Agree with multiple rounds of hair dryer on high (did about 60-90s each time), and with having to out the suction cup over the home button. You don’t need a big gap to pry it open - it’ll be slight …

Johnny Emrica -

Patience is the key here. Expletives and patience. Like previous comments say, putting the suction cup over the home button (I used packing tape to maintain the seal) will allow you to apply force to the proper location to separate the screen. Good luck!

J Rawlinson -

Get a suction cup pliers. It’ll make this part fun

Bradley Steiner -

iSclack EVO opened the iPhone easily even without heating with no fear of accidentally over-opening it like with a simple suction cup.

Matti Haveri -

Step 6

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
Insert an opening pick into the gap.
The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

The screen on my phone was so broken, a suction cup did not work, so I softened the adhesive with a blow dryer and used a Jimmy to carefully pry open the phone from the bottom just enough to slip a pick in.

charguy - 31/05/18

Just completed a smashed screen replacement, this is probably the most time consuming part. Used packing tape to cover the screen to help create a suction surface (had to replace it a couple times because it pulls away after a purple good pulls ) Used consistent heat for about 5 minutes, then stuck a pick in the tiniest opening… and pry pry pry!

Brian Gill - 29/09/19

I failed at this step. No amount of heating, pulling, and rocking opened up enough of a gap to slip in even a knife let alone the blue plastic tool. That's with a phone that has an undamaged screen - just trying to replace the battery. Apple won this round :(

Michael Sherman - 31/05/21

Be really careful here. I placed a sucker to the front and rear to help lever off the screen. However, the whole thing came away much easier than I anticipated and I ripped the front part completely away from the rear, tearing all three connector cables. New iPhone required.

Chris Wood -

Note that the opening pick they show here does not appear to come with the kit, which is a bummer! The plunger, the mini blue crowbar thing, these are too thick. I ended up using a really thin guitar pick.

Johnny Emrica -

Following careful methods can mostly preserve the seal and reusable. Won’t be as water tight but probably still pretty good.

Bottom edge is pull up with suction + separating tool. Use small precision scissor to cut any tape that gets overly stretched upon initial opening.

- For the 2 long edges, use an exacto knife to separate the seal from the screen. This keeps the tape on the chassis. Go slow along the long sides. Becareful to avoid scratching the paint on underside of the screen’s edge.

- Top corners have a thick sealed tape. Best to just use separating tool to twist it open.

In summary, top and bottom edge use separating tool. Side long edges can use exacto knife to gradually gently separate the seal from underside of the screen’s edge.

Howard -

4 picks and an exacto knife, plus 45 minutes later, I finally got it to open! Thanks tor the tip!

Cat -

Intact screen, check. Tool kit, check. Hair dryer hot enough to make the phone too hot to touch, check. Following all instructions, check. Screen still in place and refusing to come off, check.

I heated, reheated, pulled and pulled. I simply could not get it off. Worked at it for an hour and a half, and I’m not a small guy. Yes it is hard to hold, but could get a grip. Just could not get it to budge. Off to the iPhone repair shop tomorrow. Anybody want to buy a repair kit and replacement battery?

Jim Meyers -

After struggling for 30m, I looked up some alternate methods and found this helpful:

https://www.youtube.com/watch?v=25zAK5mG...

- I used a utility knife and pried up right under the home button

- the angle matters! I was trying to go too far down before going in. The top surface of the phone is rather thin, so you go in after barely getting under the chassis lip

- tilt utility knife left to right once you’ve got it under to work it in

- leave the utility knife in, and now add that pick

Jared Wilk -

Pro-tip: don't be an idiot like me. Instead, remove the screen protector you have on the phone before applying the suction cups. Derp.

hunter.geofizz -

I struggled with a hair dryer at first and a singular suction cup. However, I tried putting packing tape on the spot where I put the suction job (even though my screen isn't cracked) and I was able to do it first try with ease. Definitely recommend packing tape.

Alessio Toniolo -

Suction cup pliers. Dead easy

Bradley Steiner -

Step 7

Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.
Stop near the top left corner of the display.
Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

My Plektrum worked ok, but the edges broke off a bit towards the end

griffin.weber -

Step 8

Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.
Don't insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

No pick in the kit you sent me.

Ted Cooper -

Step 9

Gently pull up on the suction cup to lift up the bottom edge of the display.
Do not raise the display more than 15º or you'll risk straining or tearing the ribbon cables connecting the display.
Pull on the small nub on the suction cup to remove it from the front panel.

Step 10

Slide an opening pick underneath the display around the top left corner and along the top edge of the phone to loosen the last of the adhesive.

I did end up using just a smidge of IFIXIT adhesive remover along the edge before opening and that seemed to really help

Karen Flowers -

I have been using the pointed tweezers to pull the adhesive strands apart and out as the display comes off.

Adam Yavner -

Step 11

Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.

Step 12

Open the iPhone by swinging the display up from the left side, like the back cover of a book.
Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.
Lean the display against something to keep it propped up while you're working on the phone.

Nach RECHTS klappen - nicht nach links!

Manfred Wachtel - 12/05/20

Als ich das Flachbandkabel auf der rechten Seite sah, hab ich mich auch gefragt, ob die das mit nach Links klappen ernst meinen, und das „Buch“ lieber auf japanische Art nach rechts aufgeklappt. Das sollte dringend in der Anleitung korrigiert werden!

Sebastian Plickert - 23/04/21

“Up from the left” means lift up the left side.

Which is the same as folding to the right.

“Like the back cover of a book” explains it even more clearly.

Maybe it gets lost in translation?

Nick Shtangey -

Fold to THE RIGHT - not to the left!

Jim Glenys -

When I saw the ribbon cable on the right side, I also wondered if they were serious about folding it to the left, and the "book" would rather be opened to the right in the Japanese way.This should be corrected urgently in the manual!

Jim Glenys -

Hi Jim, the display opens from the left side, toward the right side. It should look like the back cover of a book. Hope this helps. Good luck with the repair!

Adam O'Camb -

Step 13

Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:
Two 1.3 mm screws
Two 2.8 mm screws
Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.
Remove the bracket.

Not Y000 this time haha

Easy Repair - 19/03/18

can same length screws mixed up?

Brook布魯克 - 21/11/19

It is not ideal, but possible for these screws.

Arthur Shi - 21/11/19

using the repair kit i purchased with my screen replacement, i am currently having issues removing these screws with the PH000. please help

Mark Ordaz - 25/04/20

I was too, thankfully I had another set that contained the PH00 bit, that worked great for me.

William Mitchell - 04/05/20

Ok. My screw is stuck. How do I remove it? Philips head is stripped.

Kristina Graham - 12/09/20

Solved it myself. Firm pressure did the trick.

Kristina Graham - 12/09/20

Takes a little pressure with the Philips head

John Toth - 13/10/20

Upon this step, I noticed I had no bracket or screws. I had my screen replaced previously and I’m disappointed to find out the repairperson made no effort to replace these parts. I’ll start trusting myself more to do my own repairs.

O D -

took me awhile to figure out I needed to use PHOO bit for the 2 -1.3 screws

Karen Flowers -

It is important to keep careful track of the screws' position. Have a tidy workplace -- a few times when I tried to re-attach the very tiny screws with the tweezer, they slipped and flew away and I almost lost them.

Matti Haveri -

can you strip the screws / how can you tell if its strip or not

antonio -

Step 14

Use the point of a spudger to pry the battery connector out of its socket in the logic board.
Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

Make sure you pry the battery connector off from the right hand side as shown in the picture. Theres a delicate component on the logicboard near the battery connector called a Mosfet which is linked to the battery charging software. If you knock it off accidently you’ll loose battery charging and the phone will boot loop and youll need to have it re-soldered back on.

Gareth - 23/08/20

I can confirm this as I learned my lesson by unknowingly prying the mosfet off. The phone will not charge now and is useless. I really wish they would add a note about this on Step 12 as a warning.

Jeff -

So this is it. You don’t have to go any further removing the screen. You can replace the battery right from this point.

John M - 02/12/20

I wish I saw this comment 2 hours ago

Kenneth Moore - 12/05/21

If I have to repeat this, I'd also consider removing replacing the battery at this point. The loose display must be then carefully fixed so the connectors don't break. And then it is not possible to re-attach the waterproof seal.

The waterproof seal was included in the kit, but there were no instructions for it so I now skipped that. I later found YouTube video which seems to describe it (starting at 7:40):

https://www.youtube.com/watch?v=RcgGRhaX...

Matti Haveri -

This is where I broke my phone, a phone that was working quite well, paid for in full. Just because I had a cracked screen. Be super careful when connecting the cables. I was in a hurry and not paying attention, used too much force when re-connecting and broke those teeny little pins that could not be repaired. A tech tried for an hour to no avail. cautionary tale. Good luck

Karen Flowers -

The display ribbon is a certain length and allows for some give, but behind it is hidden the Home button/TouchID ribbon, which sits against what amounts to a razor blade. This ribbon is much more taut than the display one, and therefore you have far less freedom of movement than you think you do. This is absolutely an intentional trap to discourage replacing your own battery. Quite frankly, it’s despicable.

Anyway, so beware of that, because although I was very careful and did not even swing the screen very far (not more than 90°), the Home button ribbon tore and now needs to be serviced. Home button is disabled now.

Apple should be ashamed of themselves for this. Please do look at the legislation effort that people are doing to try to get this kind of sabotage illegal, as well as all sorts of other gimmicks they pull. For a company that makes phenomenal products, they’re controlling like an abusive spouse.

Dan Knight

daniel -

That happened to me and I could not figure out how it got broken. It's the home button and fingerprint reader.

But I'm not bothering to get it fixed and I'm not replacing the entire screen. I went into system prefs/accessibility and activated the on-screen home button. Oh, well.

robin -

I cannot get the new battery reconnected to the connection port. Any tips/tricks? New and old battery connections appear similar. It wasn't difficult to disconnect to old battery.

Robert Ast -

Some reports here seem to indicate that the battery must be the very last connector to re-connect because otherwise there might be malfunction in some display components?

It wasn't difficult to disconnect to old battery. But the most difficult part for me was to get the new battery reconnected to the connection port. I tried many times to carefully position and press it down with my fingertip or the flat end of the spudger but it did not hold its position. Maybe I pressed too weak because I was afraid breaking the connector and the mosfet above (?) it. But finally to my surprise it connected (at that point I temporarily booted the iPhone with the loose display to verify that the battery was connected). Whew, it succeeded!
