I use my series 2 for sleep tracking and as an alarm clock every night. The battery lasts for ~2 days, and since the battery is so small it charges really quickly, so topping it off before/after bed for a few minutes is enough so it's always charged.
- kejaed 9y agoWhat app do you use for sleep tracking?
- rhinoceraptor 9y agoSleep Watch, it runs automatically so I don't have to bother with it. I'm not sure how accurate it is, though.
- RobSim 9y agoI use AutoSleep, which has been very accurate after tuning for me. (not OP)
