r/ios on Reddit: Battery Health deteriorating like crazy on an iPhone 12
June 3, 2021 -

When I first bought this phone almost a year ago I always charged to 100%, rarely overcharging. Occasionally I drain the battery to 0% and charge it then, or if I need to go out and think the battery won’t suffice, I’ll charge it then too (maybe from 20% upwards). All along my Battery Health has been 100%.

Last month I decided to check my Battery Health after months of not checking and to my horror, it was 91%!? I immediately Googled methods to retain a decent Health and decided to keep my phone battery between 30-80%. I admit I haven’t been true to this always; sometimes my phone battery falls below 30% and I still use it but generally I don’t charge above 85% any longer. Exactly a month later today I checked my Health again to monitor if this method really works and guess what? My Battery Health is now at 88%. What the heck is happening 😭

I was an Android user before and as we never had this feature I was never concerned with my Battery Health but from articles I read online this is a major thing for iPhones? Am I overreacting?

What do I do to keep my Battery Health at its optimum? It’s only been a year and this phone is meant to last me at least 3 years but at the rate the Health is deteriorating is this even possible?

Apple won't replace your battery if its capacity above 80% so keep using your phone : ) as far as I know, MagSafe/wireless charging will wear your battery faster because wireless charging, in general, generates more heat. I got my iPhone in November I mainly use a 5w brick I have to charge my iPhone and my battery health is now at 99% already.
