I have the similar problem - battery discharges very quickly. I'm using standard kernel, latest CSSU stable (and Battery Patch), battery is Nokia's original, nor WiFi or Bluetooth are not turned on. It seems that some program is running on background with increasing speed (see BatteryGraph image). In X terminal top command doesn't show nothing unusal. Yesterday evening I charged battery full and in the morning it was almost empty although I switched phone to flight mode. When rebooted with ~25% of battery resulting with empty battery level indicator after phone is restarted. Only good thing was that rebooting was killed that mystery program eating up CPU recources (and battery). Can anybody help?
