I have problem with my iPhone X’s battery health after installation of IOS 15. Initially before installation it had 91% BH, but soon after installation of IOS 15 battery health dropped to 84%z And i have never experienced anything like that in my phone before. I need help is it normal or there is something behind ??.
Battery health drop faster
Yes there is something behind, but maybe not what you think. Just the iPhone having a lot of work to do for several days !
