Use this guide to replace a worn-out or dead battery in your Huawei Mate 20.
Opening the Huawei Mate 20 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, we recommend to do so to avoid damage to surrounding components.
You’ll need replacement adhesive to reattach components when reassembling the device.
