Introduction

If your Huawei P9 Plus won't hold a charge you can use this guide to replace the worn-out battery.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

First switch off your phone. Remove the SD and SIM card tray. Remove the two Pentalobe P2 screws located at the bottom next to the USB C port.

Both metal plates have little hooks.  Use a tweezer to free them and unhinge the plates by carefully moving them upwards. Both metal plates have little hooks.  Use a tweezer to free them and unhinge the plates by carefully moving them upwards.

Soften the adhesive strips under the battery with an iOpener. Both flaps of the strips are placed at the upper end of the battery. Pull the first adhesive strip in a slow and constant movement. If necessary use a tweezer to get a first grip. The adhesive strips are less likely to rip if you pull them horizontally in a straight line and not upwards or in any other direction.

Use a spudger to slide under the battery. If you managed to pull out the adhesive strips you can easily lift out the battery. Otherwise use the iOpener once more to soften any adhesive leftovers. There are no cables under the battery that can be harmed. Remove the battery.
