Why do smartphones heat up?

[br] [br][br][br]The answer lies in a basic property of physics: movement generates heat. Our smartphones have to physically move things around to work at all, so they have to generate heat. The amount of heat your smartphone produces is largely proportional to the amount of electricity moving through it.[br][br]If you’re playing a game that demands a lot from your central and graphics processing units, both housed in a central system-on-a-chip (SoC), they will become warm, as they require more power to carry out their tasks.[br][br]Your phone becoming warm is no reason to worry, they’re designed to work that way, but if it becomes unpleasantly hot, you probably have cause for concern.[br][br]

Completely true...
The higher the intensity of the activity on the smartphone, the higher the tendency that it will become warm or hot
