Yeah I do over the AirI wonder if battery issues are related to how people update/upgrade iOS. Does doing an over the air (OTA) update cause the battery issues? Has anyone backed up their phone via iTunes, do a full reinstall of iOS 14 using iTunes, and restore your back up via iTunes? If you have, has that fixed the battery issues?
I'm old school and only trust using iTunes to update/upgrade iOS since it does a full wipe of the previous iOS version and installs the complete new one. I have not had any battery issues (so far) all the way back to iOS 4 (iPhone 3GS). I know it's only anecdotal evidence.
