Sometimes I have the same issue, sometimes I don't. I don't know what causes the different usages durations for me, usage or non usage doesn't seem to factor in. I always leave it to charge until its 100%, sometimes I get 8 hours, sometimes I get 48, its really weird. I use the fresh 2.1.2 ROM, and the newest radio, but have had this with other radios / ROMS. I can be on the phone all day texting, internet, whatever and it doesn't seem to phase it, other days I leave it on my desk all day but it just kills the battery.

I use curvefish's Batterlife widget, which gives a % of battery left, and really helps out, all i can say is get a car charger($15 @walmart,) they come in quite handy when you end up with a bogus charge!
