Guys, I'm in a dilemma: I don't know if it's my impression of me but my iPhone 12 Pro Max arrived at the end of the day with 50 to 60% battery when I bought it and with iOS 14.3 or earlier. Currently, with practically the same use, iOS 15, I am reaching the end of the day with 20 to 30% battery life. It has 94% battery health. Some fast and 1080p footage ends up heating his back next to the cameras, which did not happen before, I believe. At least I've never noticed. I'm thinking of formatting it via iTunes and restoring the back-up. Could this solve my problem? Does iTunes back up the entire device, including its settings, as well as apps and bank cards in Wallet? Thank you very much!
