Mine lasts 24 hours & I only use it for phoning & texting, it loses charge overnight!
There are lots of guides around. Here's a good one: Battery Recalibration ProTip - Android @ MoDaCo
If you don't have clockwork mod installed some of the rom tools will reset the stats fully booted. All methods need root access afair.
Thing is what do you have running and are you considering the effect on your battery?

It goes without saying: If you want to extend battery life between charges you need to be running only what you need.
