My iphone 6s overheating and battery draining
I've looked on the forum and haven't as jet found a solution. My iphone 6s has just started rapidly overheating, showing the temp warning and draining the battery. If I start using it within minutes this happens. I've check the battery usage and analytics which seem OK. I've updated the latest iOS update. I've deleted apps recently updated and reset all settings. Nothing has worked. I'm reluctant to do a DFU restore as other comments mention this doesn't work either. Help
iPhone 6s, iOS 14
