After 4.5 months my battery health dropped to 98 percent. What is the reason for it and advise on solution. Is battery replacement comes under warranty
It’s question for apple support team
iPhone 12 Pro, iOS 14
I have seen a iPhone 11 Pro Max drop to 93% after it’s been used for a little more than one and a half year. I guess you can conserve the battery health by charging it to 80 or a little over, the OS automatically slows down the charging process afterward.
Make sure this option is turned on on your phone -
Settings > Battery > Battery Health > Optimised Battery Charging
