Mine was the same way when I first got it. I suspected the reason behind the battery draining so quickly was due to the new processor (with its 64 bit architecture) and the new M7 comotion processor, but after more use I figured that wasn't the case. I moderated my usage of graphics-heavy apps or how I was multi tasking and after a few battery cycles it seemed to boast normal battery time compared to my previous iPad 2.
