Battery health information is an approximation, no two phones are going to register the exact same.
Batteries degrade over time with usage, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.
