The biggest battery eaters are 3G and Wifi. Bluetooth and GPS will take a decent chomp out of it as well. I've got mine to the point that a day of light usage brings the battery down only about 10%, light usage being just a few phone calls and a couple facebook updates and such.
I have the European Hero in the US, so of course I have 3G turned off. I also use the Locale app to manage when my Wifi can be enabled. Also, I have the setting ticked that turns off the wifi when my phone is asleep.
I get the feeling that 3G is probably the largest battery eater by a pretty fair margin, and when your phone is using it to update several times per hour, it can use a lot of the battery. You should consider giving turning off the 3G a shot, only enabling it in order to do web browsing and video streaming.
