If you can stay in a good service area or on Wifi, then that will be a low power draw.
Really? Man, I must be doing something wrong. I get awful battery life. Rooted, stock ROM. Here, I took some screenshots from two separate days last week:
This is from when I take the phone off the charger at around 8:15 to head to work until whenever I took the screenshots, approx. 6 hours later, so early afternoon. I think the most annoying part is that, as you can see, the random reboots can cost me up to ten percent of my battery. It's very irritating.
