There are many possible causes of crappy battery life that might invisibly go away, and they are discussed in the many battery life threads. One of my favorites is the cell phone switching from one type of signal to another.

i have similar experience with NITdroid...
more then 5hrs of On-screen(continual use till battery cry for recharge) time and 4hrs on wifi hotspot... more then 15hrs on normal use...
and it was cold too as you mentioned
the reason i felt for it was 'heapsize' which was not set by me so it ws '20m' only & no swap...
after changing both of them i.e heapsize to '36m' & enabling swap.. NITDROID BECAME A MAMMAL i.e always hot & hungry
this is what i observed, it might be wrong
so is there a similar concept of heapsize in maemo too

@knoxy420,
What kernel are you using?
Are you loading the bq27x00_battery module?
Can you remember if you did anything in these last days that might have affected the kernel?

Every BL-5J has a chip inside which keeps track of the amount of charge a battery can hold. It seems like yours was off by a large amount or simply defect.
You can re-calibrate it yourself or purchase a new battery if the one you're currently using does turn out to be defect.

you're aware that the speed patch is generally not considered good?

One day it would die quickly. Now it lasts all day.

Whatever was eating batteries was generating a large amount of heat so that the phone was always noticibly warm. I figured there was a short somewhere or something.
My N900 used to have terrible battery life. 3-4 hours max. really crappy. I talk all about it in this thread
Suddenly, yesterday I noticed it had gone ~8 hours and still had juice. Today, 14 hours after I took it off the charger, it still reports 35% battery. This is after 9 months of crappy battery life.
WhhaawwtThaFaaarrk? 400% increase?!?
Why is this? I'm afraid to reboot it else the magic will escape!
Anyone care to speculate on this? I'm really interested in folks ideas on this.
Here's some stats & observation.:
I started poking around and found lots of this in the syslog:
And for comparison (see my other thread), here's typical top output:
