Has anyone had any weird battery life drain? I took it off the charger around 6:30am, and by 8:00am I was at 81%. I restarted the watch and the phone.. 8:12am I was at 81%. Right now I'm at 76% (10:02am). So I seemed to have fixed the issue. But definitely made me nervous. What if I didn't catch it. And now I definitely need to buy another charging cable.
