same issue here with Xs Max. Right after an upgrade to ios 14.2 things changed completely battery drains so quickly within few hours of just texting and phone calls battery drains off The phone gets really hot even after shutting down all background apps, tried hard reset thought it might help or may be its something to do with apps I deleted all apps but the problem is still there This is completely annoying any help?

My Xs Max drains so quickly after an upgrade to ios 14.2 at an alarming rate I have to move with my charger everywhere I go unlike before an upgrade where I could charge it once after 24hrs. I also noticed that it takes forever to get full charged I have to let it charge overnight otherwise it takes 4-6hrs if I use and charge at same time. Battery has never been an issue with previous ios softwares Any help please?
