Use this guide to revive your iPhone 8’s battery life and performance with a new battery. If your battery is swollen, take appropriate precautions.

This guide instructs you to completely detach the display assembly. This is intended to prevent accidental damage to the display cables. If you feel comfortable removing the battery without putting undue strain on the display cables, you can skip the steps for detaching the display.

While it’s possible to remove the adhesive strips securing the battery as soon as you open the phone, the written guide strongly recommends first removing the Taptic Engine. Pull-stretch adhesives are designed to be pulled at a shallow angle. Doing so reduces the risk of breaking the lower adhesive strips accidentally, either by snagging them on the Taptic Engine, or by pulling the strips at too sharp of an angle.

For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

  1. iPhone 8 Battery Replacement, Remove the pentalobe screws: step 1, image 1 of 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.

  2. iPhone 8 Battery Replacement, Heat the display: step 2, image 1 of 1
    • 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

    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.

    • 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 - Ответить

    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 - Ответить

    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!

    • 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 - Ответить

    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 - Ответить

    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 - Ответить

    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 - Ответить

    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 - Ответить

    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 - Ответить

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

    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?

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


    - 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

    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.

    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.

    • 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.

    • 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.

    • 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.

    • 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.

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

    • Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:

    • 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 - Ответить

    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.

    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 - Ответить

    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.

    Hi ifixit, if you find my method dangerous, please remove it.

    After Step 17, I skipped Step 18 to Step 28.

    At Step 29, I lifted up the four adhesive black pull-tabs to expose the white adhesive side. Next, I use hot air gun and blow on the back cover of the iphone for about a minute (maybe a hairdryer will work too) .

    Warning: Don't overheat the iPhone, or you may accidentally ignite the battery.

    I think the temperature was around 60 DegC.

    Extreme Caution: Do Not overheat. I use my hand to gauge the hotness. Careful not to burn yourself or the board.

    I was able to pull out all the white adhesive tapes easily as the adhesive soften.

    DO NOT TRY this method if you are a novice or inexperience! I am not responsible if you hurt yourself or damage your iphone!

    John - Ответить

    Hey John! I’m glad the repair worked out for you!

    From our research, applying heat does soften the adhesive strips, but it also causes them to lose structural integrity and break more easily. That’s why we normally suggest using heat after the strips are already broken. Removing the Taptic Engine definitely takes a few extra steps, but we feel that it gives fixers the best chance of pulling out the adhesive strips intact.

    Arthur Shi -

    I agree with John, skip 18 through 27. These are to make it easier to remove the battery adhesive. I replaced the batteries on two IPhone 8s. The first one I did all that stuff and the adhesive still broken and I had to carefully pry the battery out anyway. When I reassembled the phone the Home button no longer worked. Looking it up, this is apparently fairly common due to all the fragile wires involved in these steps. The second I skipped these steps and when I reassembled it everything worked fine. Not one of the eight (both phones) adhesive strips came out properly. I fully drained the batteries before doing the repairs. By the way, I use the virtual home button on the one phone, it’s a little annoying, but the phone is still usable if you’re not ready to shell out for a new phone.

    Gary Berman -

    I also skipped these steps. I won’t say it was entirely successful - two of the four adhesive strips broke and could not be grabbed with tweezers. But I had gotten most of the adhesive out already and the battery was quite loose, so I used a warmer under the phone, then gently slid a flat plastic blade under one end of the battery and slowly worked it up the phone. (Dental floss would have been safer-don’t do what I did, kids!)

    Matt D - Ответить

    Likely can skip step 18-28 and all the risks. Battery tape is relatively removable by the following method

    - use a tweezer to pull up a corner of each tape. Then use fingers to peel back all the black tab on top of battery

    - use 2 hands. Index and thumb on both. Pull about 1/4” with one hand, hold the tension and pull 1/4” with the other hand. Alternate, go slow. Pull out all 4 tape completely. I think the pause after each 1/4” while holding the stretched tape firmly prevents the tape from over stretching to become too thin and break.

    - Don’t apply heat, I would guess that makes tape softer and break easier.

    Have tried other methods and failed in the past. Pulling too fast (tape will snap) or use a tweezer to twist/roll (sharp edges will cut tape) Anyway, just use index/thumb on both hands and alternately pull slowly

    I did do 2 iPhone 8 battery change this way. One removed all tape without breaking. Another broken all 4 tape after about 1/3 pulled so likely some factory assembly differeces.

    Howard - Ответить

    I second this, this method works well in most cases. Removing the haptics helps to keep the angle low and pulling the tape as straight as possible

    Hein Blöd -

    Howards method for removing the adhesive works like a charm. The only addition I made was to slightly warm the back of the iphone on a rice pack (used for sore neck muscles—haha). Going back and forth between hands is really crucial. While on hand gives a gentle pull, the other holds the phone from moving. Slow back and forth. Thanks.

    I don’t see the point in steps 18-27 if we’re only changing the battery. I pulled out the sticky tape with taptic and all this other jazz still intact. Am I missing something? Reconnecting that taptic connection cost me 5 years off my life, needlessly.

    William Mitchell - Ответить

    Hey William!

    We instruct people to remove the Taptic Engine in order to minimize the chance that the battery adhesive will tear when you try to pull it out. The steep angle you have to pull the adhesive with the Taptic Engine installed dramatically increases the chance that the adhesive will break under the battery.

    Arthur Shi -

    since the sticky tape will usually tear anyway and it is no big deal, I agree stop at this point and take the battery out. Too many things can go wrong removing more screws and connecting/disconnecting all the connectors. Go to video instructions at this point. Wish I did.

    Bob McCall - Ответить

    My tape tore away and now my home button does not work, which from what I see is to do with the tapic engine. It seems to be more dangerous to do that than to use heat and pry the battery out (which I had to do anyway). You should at least put in an warning/option for users.

    Gary Berman - Ответить

    Hi Gary,

    The Home button connector is not related to the Taptic Engine and should not be affected by anything close to the battery adhesive. I would suggest carefully disconnecting and reconnecting the screen connectors, and make sure that there is no debris on the contacts. Be sure to disconnect the battery before you do this, or you will risk damaging the screen.

    Arthur Shi -

    Glad I stopped and watched the video at this point and skipped this step. Totally unnecessary, I used the iopener and heated the back of the phone before removing the battery with a pick and “ifixit card” came out easily. Not my first battery replacement.

    Kompletter bullshit!! Im Video wird es anders gezeigt und die Schritte 18-27 werden komplett ausgelassen. Ist auch viel besser so, da so das Risiko, dass man die Taptic Engine schrottet, wie es mir jetzt beim ausbauen passiert ist, einfach nicht vorhanden ist. Ich kann auch nicht nachvollziehen, warum man in einer schriftlichen Anleitung zum Akku Wechsel komplett andere Schritte schildert als im Video. An der Stelle hat iFixit deutlich versagt.

    Hallo Maximilian, du hast Recht, im Video wird die kürzere Methode gezeigt. Der Ausbau des Akkus ist für viele Menschen jedoch sehr schwer, wenn die Taptic Engine noch verbaut ist. Deshalb empfiehlt die Anleitung den Ausbau der Taptic Engine.

Use hair dryer 90 secs as maximum hot behind the battries and detach the batteries. It worked to me.

    Don’t worry if the socket lifts up a bit as you get it out. You’ll need to lift it up later (Step 25) so don’t push it back into place yet.

    dl7utx -

    I was following this for replacing the loud speaker. I found that during reconnecting the antenna flex, I slightly rocked the taptic connector and it came lose. I was frustrated because my pre-close up test had everything working, then I shut it down, made sure everything was connected and put it all together (including a bang-on job on the display adhesive!!) and wham - no taptic responses.

    Just finishing reseating it, fought with the antenna flex, then ensured the taptic connector was seated properly underneath. All good now.

    i cant get the small screw to tighten to hold the bracket in place. it just spins. the 2.7mm screw that is supposed to go into the lower left bottom. the 2.9mm screw that goes in lower right bottom will also snug down on lower left. I somehow messed up the hole I guess. can i use an extra 2.9mm instead of 2.7 mm ? if i can find one ? thank you

    • Remove the Wi-Fi diversity antenna.

    • Remove the two screws securing the Taptic Engine:

    • One 2.1 mm Phillips screw

    • One 2.1 mm standoff screw

    • Standoff screws are best removed using a standoff screwdriver or bit.

    • In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

    When reinstalling the standoff that connects to the Taptic Engine, I found that the pointy tip of the spudger fits really well into the little hole at the top of the standoff, and helps with getting it into place and screwing it down if you don’t have a screwdriver bit for the standoff. Hope this is helpful!

    I also found adhesive between the antenna cable socket and the connector below. I was not able to separate the two (mediocre middle-aged vision and lack of leverage to create the separation), and therefore was not able to fully disconnect the haptic engine. Instead, I gently wriggled the haptic engine out and, leaving it connected, rotated it 180 degrees and out of the way toward the bottom right corner of the phone. I am hoping that I have not damaged the thin ribbon cable. On the up side, for the first time ever I was able to remove the adhesive strips from under the battery (they didn’t break).

    I have the same issue and confirm the coax connector under the speaker …. can you buy this Taptic Engine anywhere? The one with the extra leg ?

    James -

    A hint for reassembly: carefully crease the ribbon cable upwards along the edge of the connector so the stiff ribbon doesn’t touch the engine, pushing the upper connector too far away from the engine to line up with the lower connector. Once the cable isn’t interfering, you don’t have to worry as much about breaking it or having it get in the way. It’s still tricky to get the connectors lined up. I had luck by using one set of tweezers to hold and stabilize the short sides of the upper connector (silver rectangle). I used another set of tweezers (spudger would also work) in my other hand to finesse the connector alignment and push the connectors together. Look carefully at the first photo in this step: the connector is almost exactly centered below the taptic engine screw.

    Re-assembling the Taptic Engine connector is difficult. After struggling unsuccessfully for 45 minutes I ended up bending up the metal tab on the right side of the phone with tweezers, then with the Taptic Engine tipped on end (not positioned in phone) I could get the cables connected. With the tab on the phone bent upward I was able to slide the mounting tab on the left side of the Taptic Engine under the tab on the left side of the phone case and then bend it back down. This needs to be done carefully to avoid damaging the cable on the Taptic Engine.

    Mark Dige - Ответить

    Be careful -- there are two cable connectors stacked on top of each other here, and you want to attach the taptic engine to the bottom one. When reattaching the taptic engine connector, make sure that the antenna connector is pulled back -- it is designed to sit right above the connector for the taptic engine, and just by memory it rests back in the same spot. Without reviewing the previous step in reverse, it would be easy to attempt to connect to the top socket, potentially causing damage.

Note its orientation, take it out and dont't lose it taking out the taptic engine, then reinstall it when reassembling. When reassembling, the said fixing hole of the taptic engine is not on top, but has to be pushed under a little metal piece, it won't even fit on top. Then reinstall the tiny metal piece and put the screw in.

    • Try to keep the adhesive strips flat and unwrinkled during this procedure; twisted or wrinkled strips will stick together and break instead of pulling out cleanly.

    • Additionally, do not press down on the battery as you pull the strips. Pressing on the battery creates pressure points that can snag and break the adhesive.

    • Slowly pull one battery adhesive tab away from the battery, towards the bottom of the iPhone.

    • Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at as low an angle as possible, without snagging it on any of the iPhone's other components.

    • The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

    • If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

    • If any of the adhesive strips break underneath the battery and cannot be retrieved, try to remove the remaining strips, and then proceed as instructed below.

    This was the most frustrating step of the process. I found that if you pull steadily and slowly while continuing to grip the adhesive as close to the battery as you can there is a much smaller chance of breaking the adhesive strip and losing it under the battery.

    I did not have replacement adhesive tabs for my battery so I needed to re-use the old ones. First, I pulled back the black tabs from the top and sides of the battery (Steps 28 and 29). Then I laid the phone on a hot water bottle (Wärmeflasche for our German friends) while I very, very, very slowly prised the battery out of the body using the flat end of a spudger, starting at the corner closest to the volume buttons. The battery did deform somewhat during the process, but it was fully discharged and I had no combustion problems. After a few minutes of gentle pressure on the battery corner, it started to release from the adhesive. Full removal took about 5 minutes and the adhesive tabs were not damaged in any way and happily re-adhered to the new battery.

    I did all this after skipping over steps 18 to 27 and put the new battery in place after connecting it first to the circuit board to ensure correct alignment.

    Good luck with the top two…. Virtually impossible to remove. Both of mine broke almost immediately. I tried floss and a strong thread and both broke before they did much good.

    so I took a plastic card (an old credit card would work, but you’ll have to cut it thinner or work from the sides. If you got the bottom two out successfully, you should be able to get enough lift to start prying gently with the card.

    Good chance you’ll scuff up the super-thin carbon film over the charging coil if you’re too aggressive. And DO NOT use alcohol to soften the glue because it will melt right through that thin carbon layer and make a mess. Best bet is to go gradually…. Put the plastic card under the battery, pull up a bit to add tension, and then stick a pencil or popsicle or something under the card to keep keep the tension and give it 5 minutes or so for the tape to loosen. Then pull up on the card to add new tension, move the stick up, and wait again. It’ll take 20-30 minutes. Repeat until free and don’t rush.

    • If any of the adhesive strips broke off and the battery remains stuck to the rear case, remove it by adding a few drops of isopropyl alcohol (90% or greater) underneath the battery near the stuck strip(s). After about a minute, gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • If you choose to use pry tools to lift the battery out of the iPhone, use extreme caution or you may damage the ribbon cables or the wireless charging coil directly underneath the battery.

    • If the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery. This will help soften the adhesive.

    • Heat the iPhone until the rear case is slightly too hot to comfortably touch. Don't overheat the iPhone, or you may accidentally ignite the battery.

    • Alternatively, thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

    • Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. Do not deform or damage the battery.

    • To protect your fingers, wear gloves or wrap the string ends around a tool (such as the two screwdriver handles shown in the image).

    In my case the floss caught on the sharp edge of the wireless charging coil pulling up the edge of the coil, butane cutting off the floss. I think the coil had been damaged by some previous repair, but be careful. After you pull past the first two adhesive strips, peek under the battery to make sure the floss is sliding over not under the coil. The coil doesn't look like a coil – more like a paper thin pad.

    • Remove the battery from the iPhone.

    • If your replacement battery came in a plastic sleeve, slide off and remove the sleeve before installation.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • If your new battery doesn’t have adhesive preinstalled, refer to this guide to replace the adhesive strips.

    • Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.

    • Before you adhere the replacement battery, temporarily reconnect the battery connector to the logic board socket. This ensures that the battery is properly aligned in its recess.

    • Adhere the battery, disconnect it, and continue reassembling your device.

Are steps 18 to 27 really required if you’re just replacing the battery?

Daniel Frenberg - Ответить

Hi Daniel!

The pull-stretch adhesive holding the battery has a tendency to tear when they are pulled at a steep angle. When they tear, removing the battery becomes much more difficult. We strongly recommend removing the Taptic Engine in order to give the adhesive the best chance of coming out in one piece.

Arthur Shi -

I tried doing it the ‘easy’ way without those steps. I wound up breaking the top adhesive tabs and it made it a lot harder to remove the battery and took a lot of extra time. If I had to do it again, I would do all the steps. Otherwise, things went very well. Very good instructions.

I have done both the “long way” and the “short way.” If I start with the top tabs and they break, I will skip step 18 - 27 since I will have to use the floss / alcohol / pry method anyway.

I learned the hard way that the iPhone 8 has a wireless charging coil. When the battery adhesive pull strips snapped, I used a plastic card to remove the adhesive and it scraped a big chunk out of the charging coil. You can still get the phone working again by removing the logic board, ripping the coil connector off of the coil, and putting a piece of electrical tape over any exposed copper. Next time I’ll use floss to remove the battery adhesive!

Hi Richard, same thing happened to me. I tried the best I cloud to remove the battery I also used floss, but nope the wireless charging pad was stuck and came glued with the adhesive strips completely. I soften the adhesive with no luck.

Despite lots of gentle heat and following the instructions really carefully (I’ve replaced batteries and screens a few times in the past with no issues) I now have a dark blob on the screen where the suction cup was used to remove it, and a tiny bright spot in the bottom right corner. I’m guessing that one or more layers has separated before the adhesive gave way - probably the polarizer as the blob gets brighter when looked at at an angle. It did take me about 15-20 minutes of work to get the screen off as it just didn’t want to separate despite heat and rocking as per the guide - I think it just required too much pull from the suction cup before I could get the slightest gap to get the pick in.

The phone still works fully and the rest of the repair went off without a hitch. The iFixit replacement battery seems fine. I’m going to leave it charging and hope for a miracle to happen overnight.

All went well in the end. The worst part was connecting back the taptic engine socket. That was really frustrating, but finally it worked after many attempts. The second worst part was the adhesive - what an incredibly poor design of iPhones to finish with sticky glue! Other than that the process was smooth without issues.

This worked well, everything went smoothly. I would recommend going ahead and removing the display (that part really wasn't bad to do and worth it to get it out of the way). and the haptic engine (you need the space to pull the adhesive strips). I had a couple strips break partway, IPA dripped behind the battery worked really well and this shouldn't damage the electronics, it takes a few minutes to work.

The phone powered up no problem after reassembly. Everything worked except the rear camera and flashlight. I tried several tricks I found online, but the only way to get it back was to do a DFU restore of the phone. So don't panic if your camera is black, it can be a software issue.

Total time for me was 55 minutes but some of that was rewatching the video. Easy to complete and my phone is working like new.

Couple of tips

1 - if you have a small flat refrigerator magnet or magnetic business card, lay it on your work surface, magnet side up, to hold all your tiny fasteners.

2 - no iOpener or heat gun, I used my heating pad it worked perfectly and no worries about getting your device too hot.

Thanks iFixit, definitely as easy as advertised and I couldn’t be happier with the outcome.

There is no discussion of replacing the waterproof seal and how that may work without separating the display. How can the seal be placed on the proper surface all around whilst the display is still connected?

Yishai, you place the seal in place before you reconnect the screen. This was not documented well in the tutorial. The seal replacement kit actually has three layers of plastic protective material: after thoroughly cleaning the old goo from both the phone base and the screen (which took me an hour just for that), you peel off the back plastic and align it on the phone body… I actually think it’s best to align it from the left side instead of the bottom… less chance for alignment errors that way. Then you can pull the small plastic tab to remove the front plastic… a thin 3rd piece of plastic (actually two pieces) remain and cover the goo while you attach the screen. When everything is attached, I placed a plastic card (a credit card would work) over the base while I lowered the screen and engaged the top two pins. Once those are engaged you can pull out the card and snap the rest of the screen in place. Then attach the final two bottom screws.

Gotta agree with others… it’s just not worth it any more to do this yourself. It took me three hours (one hour just to clean the old screen sealant off… anyone who says they did the repair in 30 minutes didn’t clean and replace this seal properly, which sacrifices the water resistance). The screws just keep getting tinier and crazier and you have to use magnifying lenses and strong light just to see them.

too many ways this can all go wrong now. I saved maybe $35 by doing it myself rather than having Apple do it. Not even close to being worth the headache and the risk of breaking something. This is the the last phone battery I’ll ever replace, and I’ve been replacing them since the original iPhone… for myself, my family and my friends. Time to hang up the ol’ spudge tool.

Holy Smokes, that sucked!! Instructions were fine. 1.3mm screws were impossible to get in! All tape broke but the dental floss and isopropyl did the trick. Screwed up taking the Taptic flex cable off, then tore it so no haptic now. Not doing that again!

Did I say that sucked?

Thanks for all the hard work and great comments. After reading all this I am not going to do this myself. I also changed my older phones batteries with out a problem, But this cell phone "operation" looks like an invitation to a possible frustrated conundrum or a semi-successful job.
