Got my 15PM on Oct 2. Battery manufactured August. I have 22 cycles and still at 100%. I don’t limit charging to 80% or other nonsense, I just use the phone. If the battery gets to the point where I don’t like it, the replacement fee of $100 isn’t going to kill me. Life is too short to worry about a stupid battery.
 
Every other day a new thread is coming up with same question. I wish Apple didn't include this info with iPhone. I think Apple will get sued for causing 'battery-cycle anxiety' syndrome soon. :D
 
Pro Max, Oct 9 delivery, optimized charging, battery manufactured August 2023. Charge nightly on magsafe bedside stand. Used an Apple magsafe external battery once during this time, for reference.
