Battery Health Decreased 4 % in 30 Days !

Hi everyone,

I bought a IPhone 12 Pro Max 256 GB on January 7, 20201 ! Till last days of October its Battery Health was 100 %, while in 30 days starting from then up to know it decreased 4 % in one month, so now is 96 % !

I applied every Apple Tech Support recommendation how to charge it and how to preserve it !

I didn’t use it at all for games, rarely video playing.

During the year I noticed it get warmed/ heated while using it, and I used to stop its use!

By the way, no fast charging !

How come , Battery Health dropped 4 % in 30 days? Can someone explain that?

Thanks

iPhone 12 Pro Max, iOS 15

Batteries are consumables. Battery Health is an approximation based on the why the battery is reacting when charging and in use. If you have an iPhone that you purchased 11 months ago, 96% battery health is unusually high. Apple does not consider a problem with battery health until it gets to 80%, and if it gets there prior to the end of 1-year, they will replace it under warranty.

You do not have a battery problem. There is nothing wrong with that battery or Battery Health. Stop watching over Battery Health and you will be a lot better.

Thank you for your reply. It surprised me why it decreased within 30 days all at once (-4%).

Anyway, thanks one more time.

Kind Regards,
