I don't use my phone most of the day when at work, it checks for new email every hour, I check twitter a couple of times during the day but that's really it, when I get out of work after 9 hours battery is around 30% and as I say that's with really doing nothing, My iPhone 4 used to be around 70% once I got out of work with the same amount of usage.
I know if I took to listening to music on it at work it wouldn't survive to lunch time, my iPhone with a good 8 hrs listening had 50% battery left after work.
