80% charge limit
I have my 15 pro set to 80% charge limit it was doing this today it’s gone past . Is this a bug or something elsey I’m on iso 18?
iPhone 13 Pro, iOS 17
According to Apple, the battery will still charge to 100% "on occasion" to help with accurate Battery Health calibration.
It is an open question as to how often "on occasion" might be since we've seen user reports of weekly, a few times a month, monthly and longer.
My opinion.......the 80% limit thing is mostly a gimmick. Yes, the 80% limit might provide the battery with a month or two more total life, but for me the ability to start each day with the battery at 100% is much more important. I can get 2+ more hours of use from the battery each day by ignoring the 80% setting.
