How to replace battery procedure

The closest I came to finding a written, iFixit-style guide for you was one made for a Huawei Mate 20, not a 20 X, but comparing it to the 20 X, I didn't see any obvious differences in the procedure. So be aware that there could be very minor differences if you decide to follow this guide; common sense will easily get you through it if there are any. Note that this site is in French, so you'll need to use a browser like Chrome that does translation if you don't happen to speak French.

On the other hand, if you're more of a visual learner and prefer a video guide, then I have just the right one for you.

Whichever one you choose, be sure to take lots of pictures as you work and once you're done you can use them to create your own iFixit guide to Huawei Mate 20 X Battery Replacement. It's easy, fun and will earn you the appreciation of the repair community.
