When I had an iPhone 13, it was mounted in my car right in front of an AC vent; so when I went for a drive anywhere, the cold air would make the device very, very cold to the touch. One day my wife and I were in the car, discussing the differences between her Android and my iPhone (She's a Samsung fangirl). I told her "On hot days like today, my iPhone 13 cools itself to avoid damage. Here, feel how cold it is" handing it to her. Believe me, she was impressed! Until she realized she had been conned . . . 😎
