Why does the iPhone screen pop up “IPhone needs to cool down before using it” even though it has not been used in a while. Temperature here is 30C.
How do you fix this, (This message randomly came on a day).
How are you supposed to fix this if I already closed all tabs/apps, screen brightness lowered very much?
iPhone 6s Plus, iOS 15
If the surroundings are too hot, for example if your iPhone has been in a hot car and windowsill, the message will appear. I've experienced it a few times when I've forgotten my iPhone in my car on a summer day. There aren't any features you can change to prevent this from happening - the only thing you can do is make sure the environment around your iPhone isn't too hot.
