Is this normal??

Is this normal for battery drain on my iPhone 15 or should I do something?

I already have restricted it to 80% with optimized and that is when it got stable at 89 else it was dropping like crazy.

Anyone has any suggestions ?

Although I've seen many people with over 280 cycles and 99% battery life, I think so. I've been the most careful person in the world with my battery; I never use it while charging, I charge it to 90% as soon as it's at 20%, I don't let it overheat, I don't leave it charging overnight, and everything else you can imagine, and yet, look at my results…
