IS (both in body, and in-lens) has elements that float. IBIS and newer optical IS systems use the electromagnets that move the IS elements for stabilization to hold it steady in the center when the IS is off. So the electromagnets are still operating (thus the subtle hum), but they aren't counteracting movement...just holding steady.

Wouldn't that consume battery when idle?

Does this also mean that when I turn off the camera or remove the lens from the body that the floating element is jiggling around? That sounds less safe to me, for I'm not very gentle with my backpack. Should I be concerned?
