The GPS is a battery killer on the N900, only 1hr can take away 20% easily. I don't use GPS on my N900, besides, the maps from Venezuela are like a draw from a 4yr old boy, I mean ONLY 2 LINES WHERE THERE ARE LIKE 20 ROADS!!! but that is another story...

To be honest, I don't understand the battery usage pattern of the 900 myself. I usually find it performs better once it drops a few percentage points. Like for example, it would drop from 95-85% pretty fast.
My N900 drops from 97% to 85% pretty fast too, but also stays on 0% for 1hr almost.

PS: Just discovered, the second smartreflex command (echo 1 > /sys/power/sr_vdd2_autocomp) does not work with PR 1.2, it still remains at 0, even if you enable it.
They disabled it because of the unstable issues. If you use titan's custom kernel you can enabled it but, again, it is unstable. In fact, I think that everyone here that says they have smartreflex enabled on VDD2 without problem haven't find out that it is not enabled like you find out
