Use this guide to replace a worn-out or dead battery in your Huawei Mate 20 Pro.

Opening the Huawei Mate 20 Pro will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water-protection.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Although it is possible to remove the battery without removing the main flex cable with the charging port, we recommend to do so to avoid damage to surrounding components.

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Before you begin, switch off your phone.
    • Before you begin, switch off your phone.

    • Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

  2. Secure a suction handle to the bottom of the back cover, as close to the edge as possible. If the phone's rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed. Lift the back cover with the suction handle to create a small gap between the cover and the frame.

    • Before installing fresh adhesive and reassembling, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • During reassembly, this is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

    • Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply pressure for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

終わりに

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%

Take your e-waste to an R2 or e-Stewards certified recycler.

I have tried this with two new batteries now. I believe the device was water damaged by plugging the charger in while there was moisture in the port. The existing battery works but doesn't fast charge and gets very hot when charging, the battery also drains extremely quickly. Everytime insert a new battery the phone just get stuck in a boot loop, bringing up the Huawei powered by android screen before restarting, I have also replaced the charging port in hopes that may of been damaged and was causing the issue but this didn't work either. Any suggestion?
