iPhone battery do not show on facer

Hello, I’m using Huawei Sport watch with my iPhone 8+.
It seems all facer faces I have tried do not show the iPhone battery status at all. It is always on 0%…
Any ideas??

Apple does not support sending phone battery status to either Tizen or WearOS watches. Sorry.
Will display zero as you have found.

Apple has system limitations that they have imposed.

I even have an Apple Watch for which they won’t allow third party face designs other than graphics from their own devices.

Thanks for this clarification
