Battery health is drain faster
I have purchased 12 pro max on March 2021.
my battery health is drain very faster. Now it’s 91% in 10 months. What is the solution for this issue on my phone
iPhone 12 Pro Max, iOS 15
Seems fine to me. Totally within Apple's nominal rating of 80% battery health after 500 complete charge-discharge cycles. With a an assumption of linear degradation and 25 charge-discharge cycles per month, after 10 months one could expect battery health around 90%. And this is more or less an estimate, as some batteries can do better or worse.
