Per the iOS 15.1 release notes, Apple is “fixing the battery calibration” on iPhone 12’s. Has yours changed since the update? Mine (12 mini) was and still is 89%, so no change for me.

According to Coconut Battery my iPhone 12 Pro battery health has been slowly increasing since installing iOS 15.1.

It was 92.2% on 15.0.2 and it's been slowly increasing since Monday and currently at 93.9%.
