There is a difference between overheating and getting warm in use. If the phone’s internal temperature exceeds a safe limit the phone shuts down and displays a message saying that it has shut down and cannot be restarted until it cools off. If this happens regularly your phone has a hardware problem and needs to be fixed.
If you DO NOT see this message your phone has not overheated, no matter how warm it feels. If the phone says that charging has paused to allow the phone to cool, that is NOT overheating. That is NORMAL when you fast charge.
iPhones have always paused at 80% when fast charged to allow the battery to cool down, but they didn’t display a message; they just paused until the phone's temperature stabilized. Users have sometimes asked in ASC why it has “stopped charging at 80%,” and this is the answer; that it has to cool down, and will resume after a pause.
With iOS 16.5 and later Apple has added a message SAYING why it has paused. But if you had never noticed that it paused at 80%, then this sounds like the update broke something. It's normal, just more information about why it paused.
