Huawei P9 Battery Replacement

Introduction

Use this guide to replace the battery in your Huawei P9 smartphone.

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 and remove the SIM card tray.

    • Unscrew the two Pentalobe P2 screws located at the bottom next to the device's USB C port.

    • If the screen is cracked you might want to use some tape to protect your eyes from glass shreds and get a better grip to open the phone.

    • Avoid to lift only the display instead of the whole phone assembly as doing so may cause damage to the screen.

    • Use an iSclack or a suction handle to separate the phone assembly from the rear panel.

    • In case you can‘t manage to lift the phone assembly out of the rear panel you can insert the pointed end of a spudger in the headphone jack opening and press the phone assembly upwards until you create a gap between assembly and rear panel. Then use the spudger to lever the phone assembly out of the panel.

    • Don't remove the rear panel completely yet. There is a cable connected to it! It is running from the finger print sensor to the display unit.

    • Unscrew the two Phillips #00 screws that hold the metal plate in place.

    • The plate, which is covering the battery connector, has two little hooks on each side. Use a tweezer to free them and unhinge the plate by carefully moving it upwards.

    • Now you can unplug the battery connector and bend it aside.

    • The EVA-L09 model has an NFC antenna adhered onto the battery.

    • If you are just removing the battery to get to the display, you can leave the NFC on the battery.

    • Mark its place on the battery with a felt pen for reassembly. Carefully peel it off and make sure not to rip or crease the antenna.

    • For reassembly, place the NFC antenna on the battery where it was before so its contacts align with their counterparts.

    • Free the ends of the adhesive pull tabs to get a good grip on them.

    • The battery is secured with three pieces of adhesive, a removable pull-tab in the center, and on the SIM tray side. A third piece of adhesive on the button side has no pull-tab.

    • Pull the adhesive tabs in a slow constant movement to free the battery.

    • Should those adhesive tabs snap, you might want to use an iOpener to heat and soften them a little bit so you can pry out the battery with a spudger.

    • There are two cables running directly underneath the battery. Take care not to damage them when prying with a spudger! You can see their position in the last picture.

    • Slowly lift the battery toward the button side and free it from the remaining hidden piece of adhesive.

    • When reassembling your phone, replace old adhesive with stretch release adhesive strips, double-sided tape, or pre-cut adhesive strips.

Just FYI, My replacement battery from Huawei doesn’t fit. The cable doesn’t reach the connector. Soldering Required!
