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.

  1. First switch off your phone and remove the SIM card tray.
    • 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.

  2. Use an iSclack or a suction handle to separate the display unit from the rear panel.
    • Use an iSclack or a suction handle to separate the display unit from the rear 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.

    If you cant get suction because of cracks in the screen, use wide tape to create smooth surface.

    If your screen is smashed, and nothing else will work (iSclack etc), you can get a thin blade between the casing and the screen assembly and the bottom. The screen assembly can then be pried out. I fought with mine before discovering this. Be careful of the broken glass.

    I struggled to remove screen with suction cups due to damage to the back case. I used a jim to pry from bottom by usb c port, worked well.

    Be very carrefull as it can open in one fell swoop !

    On my model, I had 2 Little torx screws beside the USB port. If so, the screen won’t come out with them on.

    Interesting, sure those were 6-starred (Torx) and not 5-starred (Pentalobe) like mentioned in step 1?

    • Disconnect the finger print sensor using a spudger.

    • Unplug the antenna cable.

    • Remove the sticker that sits on top of the screw.

    • 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.

    • 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 double-sided tape or pre-cut adhesive strips.

    Hi, does the LCD Screen and Digitizer Assembly with frame come with new adhesive tabs or battery stickers? I read that if there are no stickers the battery could move and cause damage. Please let me know, i would like to be sure before i place my order.

    Hi Javier! The P9 display kit does have battery adhesive. It’s visible as two orange strips, which are the adhesive release liners. We’ll be sure to specify it better in the component list. Thanks for asking!

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

excellent tuto, opération menée sur Huawei P9 avec un kit à 15€… pour retirer la batterie, ne pas hésiter à tirer dessus, pour ma part elle commençait à chauffer, j’ai dû y aller franco pour l’évacuer sans rien endommager …

Just replaced the battery on my P9. I’ve had it for a little over 2 years and the old battery was really failing. Hoping to get some more life from my device. The replacement went swimmingly. No problems disassembling the device, except that the screen assembly was properly stuck in the body, but my device had been repaired once before, so I think that might have had something to do with it. Excellent guide.

Perfect! Thanks for the guide. To get out the old battery was not easy. I punctured it and it started smoking. Be sure to empty the battery before the replacement! IMPORTANT!

Thanks a lot!

Just finished replacing the battery and everything works good, process went smoothly except the part where I had to separate old battery from the phone because it got stuck to the case but I managed to take it apart by using iopener and a little bit of force. Thanks a lot for the guide it helped me a lot :)
