iphone 11 saying temp too hot randomly
Hi,
My new iphone 11 (2 weeks) has been displaying the temperature warning multiple times a day. Sometimes the phone is in use and other times i just go to check the screen and it's up. The phone never feels hot to the touch. I turn it off and then turn it back on and it's fine til the next time it happens. I have it updated and have checked the battery health. All good. Does this mean I have a lemon?
Thank you for the help.
