Well, battery life depends on a few factors. You mentioned that you have Bluetooth on, which does drain the battery more, but also you could be in an area where it's the fringe of coverage - your phone might have to search harder for the EVDO signal, which can also drain the battery. CDMA technology also uses battery much faster than GSM, so it's not truly fair to compare them.
If you haven't already, try dimming the backlight as low as it'll go and you can still see everything on the screen just fine. This has helped me a lot with battery life in the past. Also, the battery management is something that can be fixed in a future software update.
Yes, it is frustrating, but there are steps that can be taken to fix the battery issues.
