Apple Watch 3 is not charging fully
I had a similar problem with my Apple Watch series 3 (I have the LTE model)
No matter how long I charged it, it capped at 94%. So I did a simple hard reset (hold down on the side button and the crown for at least 10 seconds or until the apple logo comes up) and that seemed to fix my problem. I think it is a glitch from the most recent watchOS.
