After running several ROMs / Phone Models, my experience has been the same:

The battery life is never going to be as good as I like.

Having said that, Juicy seems to have the best battery life without tweaking. Mighty is average, and Energy has the worst (I run Energy anyway and love it). This is consistent with my experience on the TP (previous phone).

You can tune any ROM's power settings to some degree...

You can always buy one of those HUGE batteries if you really want...
