Introduzione

Use this guide to replace a worn-out or dead battery assembly in your Huawei Watch 2.

For your safety, discharge your battery below 25% before disassembling your Huawei Watch 2. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Note: If your battery is swollen, take appropriate precautions.

Note: This guide instructs you to replace the battery assembly. However, if you only want to replace the battery itself, it’s a different procedure and you can find the appropriate battery guide here. Make sure you have the correct part before starting this guide.

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

If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.

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

Hi, i am looking for a replacement part between the button and the main component. It looks like a black plastic. I am guessing they are here to prevent cutting the metal. The thing is, after some time they are broken.

Could you please guide me on how they are called and where I could get a replacement
