The Series Six Apple Watch Is Back 90 %

i didn't know thar was a thing that i could check. It exists, but only on the watch itself. So not in the watch up on the iphone. Directly on the watch, you got to settings, battery. You scrawled to the canne to the end. There's the battery page, and then you tap battery health. And my series 98 pce, the series seventhe seven, i the six that i'm selling from last year was 90 %. Whichs it why it's back 90 ii ustai, why? But monsieurseven is not charging any more. That is the problem.
