This is why VR will not be a thing yet again. Last time the problem was displays weren't compact enough and the computers weren't powerful enough. Now the problem is that batteries are too heavy and it's basically a smartphone strapped to your face.
Get back to me when you have something like a chunky pair of glasses that can overlay a 3D world onto the real one, or even replace it entirely, and last for hours and hours and hours.
Which will be never, because that much energy density would probably explode.
