Batteries naturally lose their ability to hold a charge with time and use.


In your case, the iPhone 11 was discontinued almost a year ago. if it was actually new, it's been sitting on a shelf all that time.


Once it had time to calibrate the battery usage, it adjusted itself to the actual battery health.

It's to be expected.
