Alright, the moment we've all been waiting for: the legendary "liquid cooling" system in the S7.

It's a tiny copper twig.

Actually, it's a teeny heat pipe (thin copper tube) with less than half a gram of material, measuring less than half a millimeter thick.

This may not be as revolutionary as Samsung describes it, but most heat pipes do technically use liquid to transfer heat.

In the case of the S7, we're guessing that the pipe transfers heat to the phone's metal midframe, where it can then radiate out to the side—or directly into your hands.

We've seen heat pipes in phones before, but the growing need for them shows how phone processors are getting faster (and sometimes hotter) each year.
