I’ve had my XS since late October. Sadly I realized that my battery health dropped to 99% sometimes in April and then suddenly to 97% in Jun. Up until then I had never ran out of juice on my XS, but last week I decided to perform “calibration”, as I thought maybe it didn’t show the % correctly anymore or whatever. So I charged it fully then let it discharge until it turned off. Then I fully recharged it and to my frustration the health now further dropped to 95%. I’m not happy about that considering I’ve been taking pretty good care of my phone/battery all along... As far as I know occasional battery calibration is recommended, just not too often. Though now I feel as though I shouldn’t have done it - not even this once. What’s your battery health?
