Introduction

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

This guide instructs you to remove 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 display removal steps.

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

Video Overview

Image 1/1: Power off your iPhone before beginning disassembly.
  • 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.

  • Opening the iPhone's display will compromise its waterproof seals. Take extra care not to expose your iPhone to liquid damage after completing your repair.

  • Remove the two 3.4 mm pentalobe screws at the bottom edge of the iPhone.

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.

Image 1/1: Three 1.2 mm screws
  • 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.

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.

  • 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.

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.

Image 1/3: 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.

  • 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.

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.

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.

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

    • Do not insert the card from the right, as prying against the logic board can damage it. Also, be sure to not bend the battery, as doing so can puncture the cell and release dangerous chemicals.

    • Don't pry under the topmost section of the battery, near the volume up button and mute switch, or you may damage the volume controls ribbon cable, which is adhered to the rear case just beneath the battery.

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

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!)
