iPhone Batterie Life
Before a month I‘ve bought the new iPhone 15 pro max. Batterie life now is 99% . Is that normal After a month of normal using to godown 1% ?!!!
iPhone 15 Pro Max, iOS 17
Question marked as
Yes it is 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.
