I get at least 20 hours with moderate use with the Energy Rom.

1) find a good radio to use in your area
2) change polling interval to 25000. ( search the forum for how to do this)
3) install max's battery tweaks. ( search the forum for how to do this)
4) disconnect data when it's not in use
5) make sure the weather/other apps don't auto refresh/download data on their own
6) use LUMOS for auto backlight dimming. ( search the forum for "lumos settings" to find a thread with good settings for lumos)
7) checking email every 1 hour instead of 5 min seems to save a lot more battery for me
