My iPhone 13’s battery health dropped by 6% within just 9 months
I had bought my iPhone exactly on 14th of July 2023 and exactly today on 16th march 2024 after 9 months it declined by 9% (with in last 1 month it dropped straight 94 from 98) despite using a 5 watt charging adapter and keeping it on charge overnight till 80% it’s a drastic decline. What’s the matter if anyone can tell!
iPhone 13, iOS 17
