The battery on the Ultra 2 is so great compared to my old Series 7. I think I could get just shy of 3 days/72 hours of proper usage (this was including 1 hour of an outdoor walk being tracked, and 1 hour of tradtional strength workout in the workouts app) if I played my cards right. Charged to 95% on Sunday night 8:10pm, now at 6:50pm on Tuesday night and it’s still got 1/3 charge left. Their 36 hours was VERY kind.
The only settings I have changed are;
- turning off detect gym equipment
- disabled some background app refresh apps (but not entirely), and
- an automation to disable “wake to raise” when I am at work.
Brightness is set to default 2/3 and I have most notifications turned off (messages is about all that come through).
I am stoked, I no longer have any battery paranoia compared to having to set my old watch to cinema mode while I was at the gym after work because I had 15% battery left.
No idea how long mine would last on a full charge but my routine of putting it on the charging stand while I shower seems to be keeping it between 50 and 90% indefinitely, which I’m very happy with. I’m fairly sure that 50% would easily get me a whole day so I never come close to running out of charge, plus it’s good for battery longevity.
