Its got nothing to do with batter life. I has everything to do with the way SLR's capture the image (film or digital). No dSLR's have the option of using the display as a view finder like you find on point and shoot digital cameras.
Look though the front of the camera with the lens off. The mirror you see is the shutter. That mirror reflects the image from the lens up to another mirror which is what you see in the view finder. When you take a picture the shutter is released to let the light be captured on the film or digital camers processor (or what ever they use). That is why the view finder goes black when you take a picture. The mirror lifts up and the image is taken.
