The other day my N900 drained the battery to the point that it would no longer even charge it. I bought another one off eBay and not only did it take forever to charge over USB but it dropped from1000mah to 750mah in a little under 2 hours. I've been reading threads on here all day but I can't seem to use them to fix the problem.
Below is my output from powertop which as you can see has core at 100% on which I guess is my problem.

Code:

I've got no idea why this has started happening as I've changed nothing on the phone and I have no idea how to stop it. Does anyone know what I can do to solve this or at least try and diagnose the problem?

No idea also here what causes your core to stay on always, as rest of powertop output seems quite okay.

Just try a full power cycle:
shut down
remove battery
push power button for more than 3 seconds
insert battery
start up
and check again ...

This is really annoying because its basically rendered my N900 useless as a mobile phone as its not longer very mobile.

Make sure your using powertop with the charger disconnected, and the screen and keys locked.
You say you haven't changed any software but have you had any updates?

Unplugged the USB cable, power cycled the N900 and re-ran powertop with a sleep 10s beforehand to ensure I got the keyboard closed and the screen locked in time.
Not really sure why neon is selected as its not lit at any point.
No updates either.

Maybe you could monitor your process list for a while:
ps -e

If the process IDs after a reboot differ a lot from the process IDs after a couple of minutes without starting/stopping anything (exept the ps process itself), this could be an indicator for something, that is restarting/crashing regularely.

Edit: And use "top". Press "c" after starting top, so it sorts your processes, that use most of the CPU.

ps looks the same after being run just after boot and just before turning off the phone. Top only shows two things using cpu and that's what you'd expect, top and Xorg.

I'm beginning to think that a reflash may be in order but I don't want to rick flashing the phone if the battery is liable to die on me in the middle of it because it takes so long to charge.

Well, I had a similar issue a while ago.

Never really got to the bottom of it. Never had any trouble of that nature since.

Delete your thumbnail cache, rebuild tracker databases and uninstall kernel power settings.

Then try again (in offline mode).
