I’vE notice an huge battery drain after updating my ultra 1 to watch os 10.1
Yesterday at 00.30 am I had about 65%, this morning at 6 am the watch was off with no battery remaining (only used for sleep tracking with default sleep app)
Charged for 30min and was at 50% now after 5 hours is at 24%
Ultra 1 here. My battery is draining at least 5x the normal rate with 10.1. Today it lasted for 12 hours and the watch was warm to the touch. It usually lasts 2 whole days and 2 whole nights, and then some (on 10.0 and earlier).
