Hello,
Yesterday, I finished charging my iPhone 14 Pro at around 21:00 and by 06:00 this morning my battery level went down to 0%.
Therefor my alarm didn’t go off in the morning…
I turned off data, wifi and locked the screen.
In the “Activity” section there is also clearly no activity when it started draining by the battery. (See picture below)
What could be the cause of this drain?
iPhone 14 Pro, iOS 16
Hi Magictii,
Thanks for coming to Apple Support Communities for help today.
It's difficult to speculate why this happened. We'd suggest making sure the iPhone is updated to iOS 16.1.1 in Settings > General > About in order to rule out the issue being cause by an outdated version of iOS.
You should also see if there are any messages regarding your batter in Settings > Battery > Battery Health.
If the issue continues to occur consistently, we'd advise reaching out to Apple Support for a deeper dive.
Have a fantastic day!
Battery drained overnight
