Just updated my 1st generation iphone se with the latest 14.0.1 update the surprised to see the battery draining rapidly as we speak or so to say as I type here. This is absolutely unbelieveable. I have already done the suggested method of cloud back up and resetting the phone factory fresh and then reuploading my backup, YET the battery drain fast like a bullet train. I have done the above method of resetting 3 times and everytime I see the battery % change fast literally before my eyes. 100% --> 10% in one hour is absolute ********. APPLE needs to buck up and get this fixed ASAP. This is not a game , this is not a time to give stupid advice. The advice of re setting the phone again and again doesnt solve the issue. APPLE BUCK UP, WAKE UP or ppl are going to stop buying iphones.
