I am not on phone for hour(s) long stretches at a time ha . Though the week I am on avg. 10 minutes(sometimes more) out of every hour would be a good guess ,

Mostly web browsing, tapatalk. I do get about 50 sms , 30-40 emails though the day , breaking news stuff to.
I use gps everyday sometimes 20 minutes sometimes an hour(google tracks,trapster) . I am not talking on the phone that much , ha
Sooo to sum it up I am not constantly on as pic will show but I really never worry or think of battery life becaus I have a spare battery with IF needed I use the phone at will as far as that goes.
I have the 2.6.37.3 incredikernel(3-13-2011) with the stock volts set (245min-998max)other then that it just the normal screen brightness(1/3 up, auto brightness off), settting timing out(screen turning off, 1 minute) if I dont manually turn screen off, turn gps off when not using, turn wifi's off if I know there isnt a wifi I can use,so no real secrets on what I do.
I always use phone some Never just carried as a paper weight , no use to carry it IF not going to use it
