Yeah i'm wondering about that myself. I bought my Xs used at the beginning of December and got a used Smart Battery Case. The phone had 96% battery health when I got it and now it's at 95%. Not really a huge issue and it's possible that it was close to going to 95% anyway, but i'm wondering if using the case accelerated that process, especially with the problems i was having with the case (frequently starting and stopping charging). Would love to see more data about this and if the problems with the case affected the health. 🤷♂️One other interesting fact, my wife & I purchased our Xs Max’s about 2 weeks apart. She’s never bothered with a battery case preferring to carry a power bank. Her battery health is still showing 100%, whereas mine is only 95%. We are both heavy users of our phones.
