iPhone 16 Pro Battery Replacement
Follow this guide to replace the battery in your iPhone 16 Pro.
iPhone batteries are rated to hold 80% of their capacity for up to 500 charge cycles, or roughly 18–24 months. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery.
If your battery is swollen, take appropriate precautions.
You'll need replacement battery and back glass adhesive to complete this repair.
As of iOS 18.1, battery health should work with both genuine and aftermarket replacement batteries. If you're running an older version of iOS, you'll need a genuine Apple battery to retain battery health functionality.
After your repair, run Repair Assistant to reset the battery metrics.
