Why Do Smartphones Stay Cool Even When You're Talking for Hours?

Smartphones have a cooling system inside them, like a little fan or ice pack. When you use your phone for a long time, it gets hot, but the cooling system helps it stay cool so your phone doesn’t break. Think of it like wearing a sweater on a warm day: even if you're moving around, the sweater helps keep you comfortable.
