Just got my Apple Watch 3 from about 1 week, I use my apple Watch without sync. I sync the watch just 1 / 2 times a day then put in airplane mode. On my second charge first and second day it discharged about 20% / day. Yesterday before going to sleep was at about 50% and this morning was drained, if i push the side button i get the time + charge symbol. In settings I disabled background app updates, but i guess that app that drained my AW battery is autosleep. Any way to get battery usage by app?
