Why the Mac reference? last time I check anything from my ipaq to my nokia maemo to my ROG laptop to my thinkpad to my arduino behave the same way: they drain more power the more work they do.

Which is all again related to summatory of work over time = power consumed, same for humans, for ICE and electric motors...

I'm starting to think there is some troll creating entries with apple products just for the sake of almost divine apple status.

Edit: yay downvotes because I don't respect Mac cult. Get over it; it's a Pc!
