<span style="font-size: medium;"]How come a single BP511A battery on the 50D is said to have 640 shots of capacity? I don't see any majoy difference between the way I use the camera and the way anyone else does. Is any one here getting the battery life that Canon has claimed? It seems that I get the claimed battery life with 2 batteries.

Don't use the LCD screen or flash at all and see what the result is. I bet it'd be close to their estimate. Just pick up a couple of cheap 3rd party batteries. I've been using 3rd party batteries for some time now and they work just fine. That way you've always got a spare, and it doesn't cost you a fortune.
