Introduction

Use this guide to bring life back to your iPhone 7 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%.

Opening the iPhone 7 will damage the waterproof seals on the display. If you do not replace the adhesive seals, your phone will function normally, but will no longer be water-resistant.

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 damage its waterproof seals. If you do not replace the seals, your phone will no longer be water resistant.

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

Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?

  • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

  • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

which temperature must be used for heating? Thx

I found you need to be very patient when using the iOpener. It's worth taking your time, giving the heat time to work on the glue. When I finally got the battery out, there were some strips of glue left behind that I just cleaned off with some isopropanol before installing the new battery.

By the way, I had to run the iOpener for longer in my microwave for it to get hot enough. When it was too hot to touch, I figured it was hot enough for the batteries.

hello -

I didn't find this to be as hard as I had built it up in my mind to be; HOWEVER, saying that I need to say years ago I was the local Nokia service center in my town. But many years ago right after they got rid of analog times. Yeah. A classic installer/repairer mistake when starting something they haven't fixed or installed before is picking up the instructions, flipping through them; maybe even reading a section that is new-then tossing the instructions over the shoulder. "I got this." This usually comes right before something major gets broke. And I can tell you when you try to do it yourself and then mess it up horribly then take it to the repair shop. Well we called that "I can do it myself" syndrome and charged extra to put back together what they brought in in the box. Now knowing all this - I can't stress this enough because I am stupid, stupid, stupid. COVER YOUR SCREEN IN CLEAR BOXING TAPE AND READ ALL THE INSTRUCTION BELOW THROUGH TO THE END BEFORE EVEN ATTEMPTING THIS FIX. Take my advise.

I didn't have an iOpener, so I used a wheat type heat bag. If you do this though, make sure you put a layer of plastic between your Mac and the bag, or you'll get condensation in places you don't want it.

I started out using the iOpener but switched to my wife's hairdryer. A heat gun or hair dryer proved to be much more convenient and is a time saviour. You can heat more and the glue becomes more fluid make the next steps with the opening picks much easier

Use a hair dryer! Watch this vid: https://youtu.be/16GkvjVyOJA It is much easier to do if you heat it from the other side.

  • Heat the iOpener for thirty seconds.

  • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

  • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.

  • Never touch the iOpener if it appears swollen.

  • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

May I know the temperate limit about heating iOpener? (maximum 150 degrees Celsius?) thx so much.

I had to heat mine up for more than 30 seconds. After 30 seconds on high it was only warm. It had to keep trying different times and checking it until it got hot. I think the initial time that I put it in for was over a minute.

DO NOT USE IN NON ROTATING MICROWAVE! It will pop a hole. I had it in for 45 seconds the first time. It wasn't very hot inside and I saw it started to leak on the paper towel I put under it. Just a fair bit of advice. I think I will just stick with the heat gun. Loud but useful.

Ahhh shoot! accidentally ordered tri-wing vs tri-point (must have just looked for y000).. It seems they only did this to annoy repair folks because not everything is tri-point on the phone...

One of these connectors is for display and one is for home button/touch ID. I was disassembling one that was having touch id issues and found this smaller flat cable was torn but longer one was not....display and touch worked perfectly on the device.

Is there any way to put back the waterproof sealing after changing the battery for iPhone 7? Thanks

I too would like to know this! It's a shame they don't elaborate as such. There is this part here - Display Adhesive iPhone 7 Display Assembly Adhesive which I assume needs to be put on after the screen is taken off but this guide says it's not needed? But for a screen repair it is? Does it get placed on the phone housing or screen? Thanks
