My iPhone 12 Pro hit 88% one year in and Apple would not replace the battery under AppleCare since it wasn’t 80%. It stayed at 88% until I replaced it with the 14 Pro Mac.
I am in the same boat as you . iPhone 12 Pro Max from nov2020 89% battery health. Just wrote to apple and the answer was : bla bla it’s not 80% so it is ok, diagnostic is also ok. 30. blackesthearted • iPhone 14 Pro • 2 yr. ago. Yep, my iPhone 12’s health is 88%. Bought late October ‘20. The iPhone 11 has a battery capacity of 3110mAh, and it requires 4665mAh to get fully charged. It can hold its charge for over 17 hours which is 1 hour less than the iPhone 11 Pro, which comes with a battery of 3046mAh. iPhone 13. Like the iPhone 12, the latest iPhone 13 battery is 3,227mAh and can hold a charge for about 28 hours, depending on 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. M2EuMRt.
