I think WatchOS 4.2.3 is eating my battery. I know it's getting old (it's a Series 0) but I was easily finishing the day with 30% - 40% remaining. After installing 4.2.3 recently I'm firmly in the red, sometimes in single figures.
@colinwalker I have also noticed lower percentages at the end of the day since that update, but I also feel like I've gotten more frequent background updates in various apps, which is a trade-off I will gladly take.
@colinwalker I had similar problems with my Series 0 after an update ~6 months ago. I ended up wiping it to factory settings and starting over and it was fine again. YMMV.
@Agiletortoise @ablaze I’ve changed some settings and removed the Siri watch face (I never use it) so will see if that helps. if not I’ll wipe & restore. Thanks.
