Do you have any COVID19 contact tracing apps installed or exposure notifications enabled? Anyone in your household also have them installed or enabled?
Finding my iPhone 11 is in close enough proximity to my wife's phone throughout the day to trigger exposure notification handshakes, even though most of the day we are working in separate spaces from home. There must have been a recent update that triggered this increased activity - either through my state app or iOS. Battery used to last all day plus few hours. Finding I need to charge mid-day if I want to avoid the 20% warning trigger at night. Battery health says 94% maximum capacity and use optimized charging.
No, never installed the COVID tracking apps, never turned that feature on. No one here except me.
From LAST Tues. to Sat, my battery drain was pretty erratic. Left the phone off charger overnight, I'd have 5% drain, 3%...or NO drain. Anyway, after looking at this crazy 100% drain it LOOKED like I may have triggered my camera by accident - although it never show that app in use (odd!!)
Went to Apple Store yesterday, Genius bar and the associate confirmed my Camera AUDIO was on, but the app was never on, this looks like it caused the 100% drain. So that's a bit freakish and new. It was blamed on a "possible software glitch" - One heck of a glitch!
Other than that, battery appears to be ok. Advice was to totally wipe out the phone and start over. Thats exactly what I did last night - no "restore from backup" since I have no clue what possible corrupt file may be in the backup.
See what happens.
