I don't use my phone much. It sits by my side barely touched for days on end. When using iOS 14, it used ~20% battery per day. After four days, at ~20% I'd recharge it. Life was easy.
iOS 15 stomped on that. iOS 15 uses ~33% per day. Here's the battery this morning. Charged at 13:00 on Wednesday, which by midday Thursday was at 66% with 33 minutes of use.
What is using that much energy? Who knows? Who is using it overnight? Who knows?
So, this morning, I switched on Airplane Mode. The result:
What is going on?
fwiw, I've already turned off Find My iPhone and System Customisation under Location Service/System Service because it was making so many location queries the indicator never turned off, and as a result draining the battery even faster.
Any ideas? And nope, I'm not holding it wrong.
Edit: In all cases, Bluetooth is off.
Edit 2: Battery health is 93%
Update: This is what happened overnight: 28%->6%. Phone left in Airplane mode:
