My battery life has been great on 10.1 Just wanted to share this to show it’s not for everyone and I would say that with a new watch you should update! Mine is the Ultra 2
I last charged on Friday 17:18 and now it’s Sunday 21:18
52 hours and I still have 25% I didn’t use low power mode! And I wore it nonstop for everyday use, workout and sleep tracking!
I will charge now cause I want to use it in the gym tomorrow but the update definitely has improved my battery life!!
I have an Apple Watch SE 1 and with WatchOS 10.1 my battery started to work great. It was really bad in previous versions. I almost thought I had reached the end of the road about using the SE 1.
Ultra 2 user here too, updated from 10.0 to 10.1 on Wednesday (just got my watch Monday last week) and noticed a substantial increase in battery life as well. Wonder if it helped mostly Ultra 2 battery life over the rest of the lineup or something. Seems like a lot of people are having issues with battery life decreasing on the regular series or ultra 1 since the update.
