Hi guys, I’ve got a third generation iPhone SE (the 2022 model) and three days ago I finally decided to update from iOS 16.7.2 to 17.1.1 and yesterday I noticed battery health was 97% and before updating it was 99%. I don’t know what’s wrong with it, as this iPhone is only 10 months old. In fact, I bought it in early January this year and I never let it drain completely to 0% and I never let it fully charge to 100%, either. I mean, I charge it when battery is 20% and I unplug it from its charger when it reaches 80%. So I always keep it between 80-20% to extend battery life.

I don’t really get it, since I know people whose iPhones’ battery health still is 100%-99% after a year and mine is 97% after only 10 months.

So any advice would be really appreciated, thanks in advance and have a good day.
