14.7 is killing my iPhone 12 Pro battery just like 14.5. Wish I could go back to 14.3.
I get 1% battery drop every 6-8 minutes.
I did the bad thing where I made some changes all at once...loaded 14.7 and Visible on the eSIM of my 12 mini. I know the 12 mini's battery is smaller, but seeing a percentage drop every few minutes feels abnormal even for it.
Initially, I thought adding Visible made my phone battery drain quickly and device feel extra warm. After some testing (and even turning off the eSIM line entirely), it seems the Music app might be to blame—I'm guessing it's using a lot of energy because my car's USB port can barely keep up for charging, too. This is something that sprung up with 14.7, as it feels noticeably bad/broken.
I'll add that it seemed to be the case regardless of local music, streamed, lossless/Atmos, or lower quality. I also noticed it while using AirPods (basically went for a walk and noticed my phone got warmer than usual) or in the car.
Debating about whether or not to roll back to 14.6 while I still can or do an entire erase/restore (I already did reload the complete 14.7 IPSW).
Edit: And just after I rolled back to 14.6, I see Apple released 14.7.1. Anyone have issues on 14.7, upgrade to 14.7.1, and see things improve?
Edit 2: Unfortunately, downgrading to 14.6 broke the Home app and iCloud backups and one of my apps had a phantom icon (could delete, but not reinstall and would appear after a reboot). I nuked everything, crossed my fingers and put 14.7.1 on it...we'll see if the issue returns.
Edit 3: I set it up as a completely new device (14.7.1) and things have been fine—I don't know what was in my setup, but that didn't agree with 14.7 or 14.7.1
