I've seen a lot of references to skylake "supporting wireless charging" but with no explanation on what that means. I read this article hoping for an answer but it was not mentioned. Can someone enlighten me? What does the chipset and CPU have to do with the power supply method? I'm assuming they're not including an RF power antenna on-die, so is this just code for "we got peak power consumption below the threshold practical with today's wireless power transmission devices"?
