iPhone 15pro battery health down 99% in 7months

99% battery health is very good after 7 months. Apple says you should have about 80% after 2 years if I remember correctly.

Given that number, OP should expect about 95% health at this point, so 99% is no issue.

Are you using the correct charger that charge your iPhone 15 Pro faster? Have you recently checked for any software updates for your iPhone 15 Pro and have updated to the latest operating system 17.6.1? If your iPhone 15 Pro battery health is still down 99%, please contact Apple Support online that will make you text Apple Support to make sure you go through certain steps to help you figure out why your iPhone 15 Pro battery health is down 99% in 7 months which should not be happening since your iPhone 15 Pro is not that old unless you bought a refurbished or used iPhone 15 Pro.

Yes

I believe the OP meant “down to 99%”.
