I had a similar experience when tried using SleepAsAndroid app to finally have bearable sleeping data, I expected that it would be harsh on battery but I didn't expect that much I guess that I had around 30% or something before going to bed. I didn't try it anymore.
Have you installed something? If not, maybe check whenever your watch is looking for some bluetooth sensor or headphones? It seems to drain a lot of battery for me and I check it from time to time to put those sensors off. ANT+ sensors seems to be fine for me.
Thanks, I don’t use music from my watch so the only bluetooth connection is my iPhone (I think). I just restarted it and if that doesn’t help, I’ll do a factor reset.
I see, wonder what cause this battery drain for you, I got higher than average(I'm using widget to track discharge per hour) a few times and I think that it was some widget , as after deleting all 3rd party ones things get back to norm. Now I'm trying to re-add them one by one and track for abnormal discharge.
Hopefully reset would cure it for you, good luck with that!
