My iPhone 15 Pro is at 97% battery health after 287 cycles. My "normal" usage with "optimized charging" will usually result in a phone with 95% - 98% health after a years.
I think the major thing here is number of cycles. I normally charge once per day, at night while sleeping, and with optimized charging i almost never need to charge my phone during the day. With 80% limit enforced i found myself needing to charge late afternoon 2-3 times per week, especially towards the end of the 12 month period.
My point is that i use the same amount of power during a day, regardless of charge limit on the phone, so the number of cycles will be somewhat identical, with the only difference being that with optimized charging i start with 100% battery and plug in around 30%, and with 80% limit i plug in with ~10%, and low SoC (<20%) is almost as bad as high SoC (>80%) for Lithium batteries in EVs, and i doubt it's any different in phones.
