Smartphones feel cold because they are made of materials that let heat escape quickly, like glass and metal. When you take them out of your warm pocket, the cold air hits them instantly, just like when you pull a spoon out of soup and it feels super cold right away.
Examples
- You pull out your phone from a warm pocket in winter, and it feels like ice.
- Your phone cools down quickly when you take it out of your bag on a chilly day.
- Your phone is cold even though the inside might be warm.
