So, My n900 eats batteries in 3-4 hours. Even when idle the thing warms my pocket quite nicely.

I've checked top and the cpu is at about 3-4% while idle.

I found powerscript and have been running it to profile the system's power consumption.

When on the charger, it reports 0-10mA power draw when idle.
As soon as I yank the charger it jumps up to ~375mA, and stays at that level while running on battery. So with a 1300mAh battery, that'll get me < 4 hours. As soon as I plug it back in the power usage drops back to <10mA.

Am I interpreting the powerscript output correctly? Should it give vastly different readings when plugged into the charger or not?

I've got the power kernel, CSSU, and a few apps installed. CPU stays around 3-4%.

I've tried with gprs, wifi, bt, & gps turned off. No change.

Any suggestions of where else to look?

Thanks!
