My laptop definitely dies significantly faster when I'm making it work instead of just mindlessly scrolling on it... since the display is on in both cases I don't see what that could be but chip powre consumption making a singificant difference.
My phone dies much faster when I am using it, but admittedly screen usage means I can't prove that's chip power consumption.
VR headsets get noticeably hot in use, and I'm all but certain that that is largely chip power usage.
Macbook airs are the same speed as macbook pros until they thermally throttle, because the chips use too much power.
