strange battery drain
Problem: Battery Drain of 20% overnight and bad battery life in general.
Device: iPhone 13 mini, iOS 16.5 & iOS 16.5.1 (issue with both versions).
Now, I don’t need any common sense advice on how to prolong my battery life this is why:
- it started roughly 2 months ago, before there was no problem whatsoever, and I didn’t change my phone using habits.
- Battery health status at 92%, so hardware should be fine.
- overnight I have activated airplane mode, switched of wifi and bluetooth (I mean fully turned off not just greyed out) and I even use low power mode (also location services are all turned off except google maps, while using the app). Also diagnostics are turned off.
- I uninstalled many non strictly necessary apps. Siri is deactivated.
- I did a settings reset a few days ago and after that it performed brilliantly again for a couple of days but now, after not changing any setting, it drains like crazy again.
And still 20% gone WITHOUT any usage during all the night (during night only the clock to wake me up should be doing something):
I haven’t tried a full factory reset yet, that would be my last resort bit I’d be very grateful if someone had a solution or at least an explanation to this.
P.S. I won’t charge my battery overnight! If your fuel tank is leaking you shouldn’t just fill up continuously, it’s better to fix it first.
