iPhone 15 Pro Battery Replacement
Use this guide to replace the battery in your iPhone 15 Pro.
iPhone batteries are rated to hold 80% of their capacity for up to 1000 charge cycles. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery.
You'll need replacement screen adhesive to complete this repair. If your new battery doesn't come with adhesive pre-installed, you'll need replacement adhesive for it as well.
If your battery is swollen, take appropriate precautions.
Note: Due to Apple's parts pairing restrictions, on iOS 17.6 and earlier, you may receive warnings about your replacement part and lose access to battery health data, but your new battery will otherwise work normally. On iOS 18 and newer, all batteries should work normally. Pair original Apple batteries using Repair Assistant.

Screen information
There are two delicate cables connecting the screen to the phone: one just above the action button, and the other near the middle of the left edge.
There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in these locations to avoid bending the contacts.

Swing up the right edge of the screen like the front cover of a book.
Prop up the screen so you can access its cables without straining them.

Use blunt nose tweezers to grip the edge of the pull tab and pull it completely off the edge of the battery.
Repeat for the other two pull tabs.

Remove the stretch release adhesive
Pull one of the pull tabs out from under the battery until you can grip it with your fingers or wrap it around your tool.
Hold the phone steady using the edges of the frame—don't press down on the battery.

Orient the adhesive
Lay the adhesive next to the phone and use features like cutouts for spring contacts and the front‑facing camera to orient it correctly.
-
-
Apply the adhesive
Use the pull tab to begin peeling the back liner off of the adhesive starting from the bottom, but don't remove it all the way.
While holding the back liner out of the way, carefully align the exposed edge of the adhesive to the bottom edge of the iPhone's frame.
When the adhesive is aligned, set it down along the bottom edge.
