Here's a thought, why is this even questioned? VR is an incredible battery leech. Image quality issues aside you should turn it off when not needed.

Nothing better than learning to actually use the equipment properly, including how to properly hold and support your gear. Image shake reduction is nothing more than a tool that needs to be used ONLY when called for.
Problem is, too many people treat it like their crutch and lean on it ALL THE TIME!!!!
