Hello! My iPhone X's baterry is draining very fast and I don't know why. I disabled all the background apps and all the settings that may have an impact on battery life but nothing works. My battery even drains 20-25% during night, when I don't touch the phone. Battery Health is at 98%. 1)What should I do? 2)Is this website safe for downloading iOS 12.0.1? ipsw.me 3)Do you have this problem also?
