That battery health number is an approximation. I would suggest that you have Apple run diagnostics. Those are much more exact.

There are major issues with a number of different models of IPhone since the 16.4.1 (a) update.
This forum is littered with posts complaining about the same issue, and instead of doing something about it you have a number of users of the forum posting the same copy and past "make sure you've tried this, put your phone into power mode".
Battery keeps draining within 6-7 hours after charging.
