Eli5: Why do smartphones not need cooling fans like other computers do?

Everybody always talks about the massive computing power of smartphones (movies love the moon mission comparison) but still my phone rarely gets hot. (Only when I use it while charging sometimes)

Smartphones have massive computing power compared to moon missions, and weak computing power compared to laptops.

And they do get hot sometimes, like when playing certain games.
