Smartphones feel cold when you use them because the inside gets warmer, and that makes the outside feel colder. It's like when you put your hand on a warm cup, the cup feels hot, but your hand feels cool in comparison.
Examples
- Your phone feels cold when you're playing a game for hours.
- The back of your phone becomes cooler after you watch a long video.
- You notice that your phone is colder in winter than in summer.
