Before disassembling your device, ***discharge the battery below 25%***. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. | | | ***Note:*** This guide instructs you to replace the full midframe, battery and screen assembly and requires transferring all other components to your replacement part.
