Apple rolled out the new iOS 14 globally last week and people are having major issues, especially overheating issues. Most iPhone users have been complaining for the past few days on Twitter of overheating issues brought by the iOS 14 update.
The Overheating issue seems to be affecting a large range of iPhones from the iPhone 6S to the newest iPhone 11. They are also complaining about battery drain issues which they never had before.
Apple is yet to comment about this problem affecting its users. As you know, it is quite difficult to downgrade iOS when you get the latest version so you will have to live with it until Apple issues a fix.
