Battery maximum capacity
I got an iPhone 15 pro max and I within 31 cycle count my maximum capacity dropped to 99% is this normal? I don’t think so!!!

Yes, completely normal. On average, you can expect from 1 - 2% drop in battery health per month of ownership. Battery health decline is not linear. It may remain stable for a while, then drop a couple points. One thing you can't change is battery health decline. It only goes one direction and that is DOWN. And when the health of your battery declines to 80% or less, which it absolutely will in the future, it will then be time pay Apple to put a new battery in your iPhone.
Until then, worrying about the natural decline of battery health is a waste of your worry time.
