iPhone X same with update iOS 14, phone started to heat up excessively to the point that battery expanded and opened up my phone, no indication was given by phone that it was working with excessive energy demand or anything, did reset to original settings that strangely enough brought me to iOS 14.8 before reset I had 14.7!!!! Since I had no warranty at this point apple offered only battery replacement with 3 months warranty only and excessive cost. How ridiculous is it to charge a customer for giving such a tiny warranty time period and denying that it’s software issue, where so many other people with the same issue!!!
