I'm loving my new 550D but not the battery life (or lack of).
On my 400D I would get about 500 raw shots maybe 450 or so with an image stabilised lens (don't use it all the time).
But the 550D is a different story. I sometimes use live view. mainly when I'm using a tripod for precise focusing. I have shot a little video but I'm averaging 100 shot's per charge I've got a battery grip with 2 batteries coming in the next few days so I will try one of the new batteries in the camera first to see what the difference is.
What are people averaging per charge? I shoot raw, lowish ISO, maybe 20% with IS turned on, no flash, 30% in live view.
Thanks in advance.
