There’s definitely something fudged up with the battery on watchOS 11. Some days are stellar and some days are crap.
Topped up my AWU1 yesterday morning at 97% after waking up, spent the day with it, had a 90 min workout with it in the evening. Went to bed at 56% and woke up 7 hours later at 49%. So, pretty solid.
This morning, similar routine, I top it to 100% just after waking up, start my day and suddenly after not even one hour I already lost 5%, which is very unusual. Had to reboot to stop the drain. I’m starting to wonder if there is something bugged in the sleep tracking and/or syncing.
