Battery Capacity dropped
I bought my iphone 12 on Oct 2021, Today (27 jan 2022) i upgraded my iphone to 15.3 the battery capacity dropped from 100% to 99% within 4 months of usage. i use only apple cable and adopter. I never use my phone below 20 and never charge over 91% this is very schoking eventhough i follow this much conditions still i am facing this capacity drop
