We have similar phones. I’m now at 82% at 714 cycles. In real life, our devices wouldn’t qualify but I’m sure Apple will be allowed to write the testing methodology in a way that’ll be nice and gentle.
Huh interesting datapoint. I just checked on mine, also August 2023 15PM, and 86% @ 707 cycles here. I’m pretty careless with charging it whenever is convenient/letting it drain to 0% while traveling/etc as well.
It’s more about the calendric aging than number of cycles these days. My own stayed at 99% until ~400 cycles, and then in a few days it dropped to 94%.
