so since updating to watch is 2.2.2 my battery drain has been off the charts,,, I take my watch off at 9am and back on at 12am, I usually end the day with 50% Since the update, my battery drain is down to less than 10% yesterday it's completely drained!!! So then I updated to os3 beta and the problem still persists. Any suggestions? What could be the possible reasons? Background app refresh?
