My iPhone 13’s battery has suddenly plummeted
Yesterday my iPhone 13 (almost 2 months old, battery health still 100%) used to last me all day, no matter what I did or how much I used it I couldn’t flatten it in a day. Today I barely even used it and it died in the afternoon. I haven’t done anything different today or installed anything that I didn’t have yesterday? I don’t understand this and I hope it’s just a one time thing otherwise I’m going to be very upset as its an almost brand new phone and never failed me, and for the price it shouldn’t have problems like this.
iPhone 13, iOS 17
