In my annecdata experience deep discharge (< 5%) and partly charging (like 40 to only 60%) affect the capacity severely. There the annecdata of the OP is not very relevant.
- oktoberpaard 2y agoInteresting. I’ve always understood that partly charging was supposed to be better for battery health with lithium batteries. I’ve capped my 15 Pro Max at 80% from the start and I avoid going below 20% and it’s still at 100% battery health after more than 10 months and 159 cycles. I occasionally charge from ~20% to a random higher number during the day, but other than that I just let it charge during the night. My iPhone 12 Pro Max dropped to 90% battery health in no time without the 80% cap and a similar charging schedule with optimized charging enabled.
