There is nothing wrong with your battery, nor does it need replacing.


Batteries degrade over time with usage due to chemical aging.


You can expect about a 1% drop per 50 charging cycles (25 charging cycles for IPhone 14 and older) 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.
