iPhone 15 Battery health drops to 99%
On my iPhone 15 phone. Battery cycle was 60. After that showing 99% battery health. Is it normal?
iPhone 15, iOS 17
Question marked as
Yes, perfectly normal.
Batteries degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.
