Introduction

Use this guide to bring life back to your iPhone 7 Plus with a new battery.

This guide instructs you to completely detach the display assembly; this is intended to prevent 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 disconnecting the display.

For optimal performance, calibrate your newly installed battery: Drain it below 10%, then charge it uninterrupted to 100%.

Video Overview

Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
  • 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 3.4 mm pentalobe screws at 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.

The recommendation of discharging the battery is completely unnecessary. Even a 25% charged battery can explode. Completely ridiculous suggestion.

The risk of thermal runaway on these batteries decreases with the battery's SOC (state of charge). Below 50% charge the risk is fairly low, and at 25% charge the risk of a thermal event is near zero. If I recall correctly, the same suggestion appears in Apple's official (non-public) service manuals for the iPhone.

Jeff Suovanen -

@jeffsu Yes, that is correct. Apple does require all certified staff to discharge the battery below 25%. This is an industry standard for all LiION batteries. If you don’t want to do this, just make sure to not puncture the battery and disconnect it first thing.

Hang on a second here, doesn’t the Ifixit part I ordered come with the seals? The display assembly? It doesn’t. Now I have to wait another week?!

Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
  • 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 iPhone for about a minute in order to soften up the adhesive underneath.

How long should I use a hairdryer for?

I used it until it was hot to the touch but not too hot where you burn yourself.

  • 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.

Add Comment

  • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

  • Insert the flat end of a spudger 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, rock the screen up and down to weaken the adhesive until you can fit a spudger inside.

  • While pulling up on the suction cup, twist the spudger to widen the opening between the screen and rear case.

Add Comment

  • Insert the flat end of the spudger between the front panel and the rear case at the lower left edge of the iPhone.

  • Slide the spudger 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.

  • 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.

Add Comment

  • Remove the spudger from the left side of the phone and insert the flat end into the bottom right corner.

  • Slide the spudger up the right edge of the phone to the top corner, breaking up the adhesive holding the display in place.

  • Pull up on the suction cup to lift up the display and open the iPhone.

    • Do not raise the display more than 10º as there are delicate ribbon cables along the right edge of the device connecting the display to the logic board.

  • Pull up on the small nub on the suction cup to remove it from the front panel.

  • Slide an opening pick underneath the display along the top edge of the phone to loosen the last of the adhesive.

Add Comment

  • Pull the display assembly slightly away from the top edge of the phone to disengage the clips holding it to the rear case.

  • 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.

Add Comment

  • Remove the following four tri-point Y000 screws securing the lower display cable bracket to the logic board:

    • Three 1.2 mm screws

    • One 2.6 mm screw

Is it really safe to lay the device fully open like a book? The cable leading to the LCD gets stretched across the sharp edge of the aluminum edge of the back cover.

u204863 - Reply

Generally I'd say no, it's not safe. In reality I've seen a bit of variance in the cable length, and sometimes it'll be fine—but mostly I'd be prepared to prop the display up or hold it in place at a slight angle so it doesn't put too much stress on the cables. On prior iPhones it was easy to rubberband the display to a box or a can of soda, and something like that would probably work well here too. Use your own judgment.

The tri wing screws are so hard to remove. What's the trick?

shannon caldwell - Reply

At first I think I was being too careful and was getting no where. I got better results by pressing down on the screwdriver with more pressure while turning and those little screws came right out.

LadyTech - Reply

I cannot remove one of the corner screws in this step and i have used the tweezers and the y000 tri tip and i am afraid that it is stripping it. is there a work around for this step?

Katherine Monday - Reply

@katmonday1 No workaround unfortunately. Make sure the driver tip is in good condition and fits the screw correctly. Seat it in the screw, hold the driver perfectly vertical, press down hard (and maintain it), and turn. It’ll come out. If it’s really stripped you’ll have to get more aggressive—try one or more of the techniques in this guide or get some help. Good luck!

  • Remove the lower display cable bracket.

I am confused, please help. LOL the bracket, the very first one being removed. I see it has three screws the same size and one a different size? I've been trying to fix my daughter's phone and ordered a 0.6 mm Tri Wing screwdriver for iPhone 7 plus /Apple watch. It seems to fit the screws and it seems to be turning them although I can't see that well but they're not coming out. However when I used it on a smaller bracket with two screws they came right out so I'm thinking I don't have the right screwdriver I am at my Wit's End!! I have been working on this phone or attempting to for a while now. I cannot find a list anywhere of the exact size screwdrivers needed to Take apart an iPhone 7 plus. Any help would be greatly appreciated.

chris west - Reply

If your tri-wing screwdriver worked for other tri-point screws in the phone, then it should work for the screws you are struggling with! If it feels like the screws are spinning but not coming out, try to use tweezers to pull them out. I often struggle with tri-point screws, and need to apply some downward pressure to remove them. This can be risky though, as you do not want to strip the screw or damage components underneath the bracket. If you continue to struggle, you can give this driver and this bit a try.

  • Use the point of a spudger to lift the battery connector out of its socket on the logic board.

  • Bend the connector cable up slightly to prevent it from making contact with the socket and providing power to the phone.

Add Comment

  • Make sure the battery is disconnected before you disconnect or reconnect the cables in this step.

  • Use the flat end of a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board.

  • To re-attach press connectors, press down on one end until it clicks into place, then repeat on the other end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

  • If you have a blank screen, white lines on the display, or partial or complete lack of touch response after reassembling your phone, try disconnecting and carefully reconnecting both of these cables and make sure they are fully seated.

The note about the danger of pressing on the connector incorrectly is very legitimate. Though I find it more practical to use a wide (1.5 cm) case opener tool to press it down all at once. Minimizes risk of bending the connector.

What can happen if the battery is not disconnected before the two lower display connectors?

  • Remove the three tri-point Y000 screws securing the bracket over the front panel sensor assembly connector:

    • One 1.3 mm screw

    • Two 1.0 mm screws

  • Remove the bracket.

Posted a comment above on the first step. The screwdriver that I ordered Works taking out these two screens shown in the picture. However it does not work on the first bracket that needs to be removed. It seems that all screw sizes are somewhat different but I'm not finding a list showing different screwdriver sizes needed. Does this make sense? Could anybody please give me some advice on this thank you much.

chris west - Reply

I know your comment was posted a long time ago but just in case someone else has the same problem, the only difference in the screws are the lengths. The ends are the same.

  • Disconnect the front panel sensor assembly connector from its socket on the logic board.

  • This press connector should also be reconnected one end at a time to minimize the risk of bending.

  • Remove the following two Phillips screws securing the barometric vent to the rear case:

    • One 2.9 mm screw

    • One 2.1 mm screw

I skipped this step and go straight to step 25. I skipped it because I couldn’t get the screws to come off. But skipping those step did not prevent me or has any detrimental effects on performing step 25.

  • Peel back the three adhesive strips on the lower edge of the battery.

    • If possible, use your fingernails or blunt tweezers. Be careful not to poke the battery with any sharp tools.

Add Comment

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

  • Slowly pull one battery adhesive tab away from the battery, toward 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 a 60º angle or less.

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

Add Comment

  • Repeat the previous step for the second and third strips.

    • Hold down the battery as you remove the final strip, or the strip may fling the battery when it separates from the case.

  • If you removed all adhesive strips successfully, skip the next step.

    • Otherwise, if any of the adhesive strips broke off underneath the battery and could not be retrieved, continue with the next step below.

Add Comment

  • If any of the adhesive strips broke off and 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. It should be slightly too warm to touch comfortably.

  • Overheating the iPhone may ignite the battery.

  • Flip the phone over and use a plastic card to break up any remaining adhesive behind the battery.

    • Do not insert your card in the area between the volume down (-) button and the top edge of the battery, or you may damage the volume control cable lying underneath.

    • Do not pry against the logic board or you may damage the phone.

  • Keep the card as flat as possible to avoid bending the battery, which may damage it and cause it to release dangerous chemicals or catch fire. Do not use any sharp tools to pry at the battery.

  • Alternatively, a piece of dental floss may be used to separate the battery from the rear case. A stronger alternative to dental floss is an unwound guitar string, such as a 0.009 E string from a 12-string set.

  • Thread the floss or string behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.

Add Comment

  • Remove the battery.

  • If your replacement battery came in a plastic sleeve, remove the sleeve before installation by pulling it away from the the ribbon cable.

  • When installing the battery, refer to this guide to replace your battery's adhesive strips.

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

can the battery from iPhone 7plus fit in the 6s plus? looks to me like is the same type of connector and same dimensions so it would be an easy way to gain 150 extra mah by using the iphone 7 plus battery

Kaustubh Iyer - Reply

The display is held in with screws and clips, so everything will work fine if you reassemble the phone without replacing the adhesive. That said, your phone won't be as waterproof as it used to be. We do have replacement adhesive available for you, but we're still working on putting together a clear guide on how to install it properly. (Stay tuned!)

Will this break it’s water resistance?

AdamTGG - Reply

Yep. It’s not worth the risk. Just take the device to an Apple Store and pay the $80. That way you not only have a water resistant device, you also have a 90 day warranty on the battery AND the work performed on it. So if the phone’s water resistance fails because of the adhesive, Apple will replace the device without any additional cost.

Sooo…in Step 24, DO NOT use the metal-tipped tweezers to “jam” under the Battery and try to pry up on it. You WILL risk puncturing the battery and catching the iPhone on fire.

I’ve replaced the battery. But it won’t turn back on? I can’t force restart it because my fingerprint button doesn’t work? Can you help?

jordiehowes - Reply

If your iPhone is covered by warranty, or consumer law, we'll replace your battery at no charge. Not sure if you're covered? Check if your iPhone is still under warranty by entering your iPhone serial number.

If your iPhone has any damage that impairs the replacement of the battery, such as a cracked screen, that issue will need to be resolved prior to the battery replacement. In some cases, there may be a cost associated with the repair.

If it does not work get connected with Apple support Uae
