Introduzione
Use this guide to remove or replace the logic board in your iPhone 15.
You'll need replacement back glass and screen adhesive to complete this repair.
If your battery is swollen, take appropriate precautions and consider replacing your battery.
Due to Apple's parts pairing restrictions, much of your iPhone's functionality depends on the logic board—and without Apple's proprietary calibration process, even a genuine replacement logic board won't work. To retain full functionality, you must also replace the following parts with ones that are paired to your replacement logic board:
- Screen (to retain True Tone and Auto-Brightness)
- Front Camera and Sensors (most functionality)
- Battery (to retain battery health data)
