I’ve said this before and I’m saying this again. OTA updates always mess something up. If you guys are having battery issues, restore the phone using iTunes and set it up as new. You can still sign in to iCloud and get your contacts, notes and passwords back.
My iPhone 7 Plus is doing pretty good. It lasts for about 9.4 hours on a full charge. It’s still not as good as iOS 10. I’ve lost about 40 minutes of usage compared to iOS 10.3.3, but at least iOS 11 works as intended. I don’t lose 10% in 15 minutes.
Restore and set it up as new. Don’t get on iOS 11.1 Beta 2 because you can’t set it up as new. I updated to Beta 1 and lost about 2 hours of my usage time compared to iOS 11.0. I then restored to iOS 11, set it up as new and without even signing into iCloud, updated to 11.1 Beta 1 and then did an “erase all content and settings”, set it up as new and signed into iCloud. That’s as clean as an update can be! Guess what! No change! The battery life was still down by 2 hours compared to iOS 11.0. I was getting 7 hours of usage. That’s when I realized that updating messes something up.
