Battery health drops by 4% in a week

My iPhone 11 battery health dropped by a staggering 4% last week from 96% - 92% all in the space of 5 days which doesn’t seem normal to me because I bought my iPhone in December last year and the battery health has dropped by 8% in 6 months. Mind you my sisters iPhone 11 is at 85% and she’s had it for 2 years. Is it normal that my battery health has depleted so fast in six months?

I used a 20 watts type-c adapter and recently updated to iOS 15.5.


iPhone 11, iOS 15

Hello,

Depending on usage, that is normal and is nothing to worry about.

Generally, Apple will replace the battery under warranty if the battery health falls below 80% during the first year.

Good luck.
