Default [Q] WIFI Always on even when toggled off??

Hey guys,

Correct me if im wrong, but under your battery stats if you click on your graph it shows your mobile network, wifi, gps, active, screen on etc etc....Is it just me or even when wifi is off it shows a solid blue bar where you think there would be a gap if it is toggled off? Wouldnt this waste battery.

Is ti just me or am i missing something here?
