Just wanted to put that out there seeing as how others are getting a day+ of juice.
I'm very sure it all depends on what apps or services you have installed. My phone lasts the same as you at around 12hrs but I load it up with A LOT including widgets that refresh often.
My old galaxy s had similar battery life but then I uninstalled everything down to the basics and gave it to my wife. Her battery life lasts 2 days now instead of 12hrs when I was using it.
I am confident it is the apps we use if we realize it or not. Kernels and ROMS do help but not by days IMO. more like +/- few hours...
