Does anyone else have this problem? I had an AW4 before with 10.0.1 on it (battery health about 65%) and I could still go a full day with it. Just got a AW5 secondhand with 83% battery health that I now updated to 10.1.1. The first half an hour it maybe drained like 5% or so. Then I didn’t use it (everything like background app refresh, always on display etc is turned off also). Checked on it after about an hour or so and it had drained from 96% down to 76% without me using it. Used it for like 5 mins and it came down to 74%. Restarted it and it was down to 72% while being off? Wtf is happening with this update? Didn’t have this issue with the 10.0.1 update at all. Anyone who can relate?
