It might be different if you restore the phone. My XR on iOS 12 had 99%, then a couple of months later on iOS 13 it was suddenly 94%. Did a software restore and it's now at 97%.

So yeah, not exactly reliable.

Apple's way of determining battery health is not exactly accurate.

It’s not just Apple’s way, any battery health meter is incorrect because there’s no way to accurately measure the chemical reaction happening within the battery. It’s always a guesstimate.
