iPhone 15 Battery Replacement
Use this guide to replace the battery in your iPhone 15.
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 battery and back glass adhesive to complete this repair.
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, calibrate authentic Apple batteries using Repair Assistant.
