Are you mad? Your CPU isn't reaching sleeping mode (C4), no wonder your battery life is toast. Please paste the output of powertop. Rerun top and WATCH it. what is the NICE load shown at the top?

Right, so we have a background process hosing yer juice. Lets just confirm you are disconnected while taking these readings?
Install powertop as below:

.edit
To install powertop IIRC:
-Enable devel repository (normal warnings apply)
- With root:
apt-get update
apt-get install powertop
apt-get clean
- Disable devel repository.
- Run powertop

You could run powertop for a while when the device seem to be idle and not in use. You will know from the output if something keeps CPU busy.
Code:
Nokia-N900:~# powertop -t 1200
Powertop 1.13.3
status: Unknown job: pmtrackerdaemon
Sleeping for 11 seconds before sampling
Collecting data for 1200 seconds
Sample interval was 20m 00s 17243us

--------+--------+----------+-----------+--------+
C0 | 2.6% | | 1150 MHz | nan% |
C1 | 0.3% | 0.2ms |
C2 | 3.9% | 2.2ms |
C3 | 23.3% | 282.2ms |
C4 | 69.9% | 750.6ms |

"Normal" CPU Usage.
I had this issue previously wehre the proc was never reaching a C4 sleep but on removal of Pedometer Home Widget suddenly battery life returned to normal and my proc spent ~80% of it's time in C4 sleep. It also went from ~30,000 HW wakeups to ~700 in Powertop.

so that we can check your battery isn't borked - then reboot, wait for 3 minutes until system is fully loaded, run powertop from terminal, lock the screen and keys and post up the output too.

maybe the battery should be replaced?
any other hints?
