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
- Your phone cools down quickly when you take it out of your bag on a chilly day.
