Huawei Mate 20 Pro Battery Replacement
Введение
Перейти к шагу 1Use 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.

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?
Excellent Step by step guide thank you
