Yeah, WatchOS 10 is definitely a drop from WatchOS 9, but it was still useable levels on my Series 7 until 10.1.1 (ironically this version was supposed to fix people with massive battery issues), and now i’m not making it much past 12 hours with Always On Display turned on and no major usage.
The bad news is I also went to the 10.2 beta a few days ago and its no better.
I am wary of a stat that says “up to” rather than “on average”
Yeah, unfortunately 10.1.1 was the worst battery life of any 10 release so far for my series 7, and the 10.2 betas have only been marginally better. It really doesn’t seem like Apple know how to fix the underlying issue at this point.
