[question] CPU is using power but nothing is active
 
Hi gang,

nothing running the background but Battery Graph is showing loss of energy on the CPU...
There are bars going up and down?!

How can I determine what is making my battery run dry?

Try downloading the memcpu applet instead and check if there actually is something using the CPU. Perhaps you have a daemon running? Or maybe the music indexer daemon have stucked and is using a lot of the CPU(IIRC that can happen)?

EDIT: Or, run the command 'top' in terminal, there you can see what uses the CPU.

Will give that a go....
Thanks....

Never noticed it before.
I usally set the cell off-line during the night but still something is running...

Edit:

Provides no new info...
I also have the load applet and that one also shows 3 boxes....
When I check Conky there is 1 process running; being Conky

I also used Htop but don't know what process to stop??

Is one process shown consistently using CPU - other than X and htop?
Also - what battery life are you getting?

I second rolan900d

Is there a way to log various daemons/apps/widgets/etc CPU usage?
My N900 suffers from serious battery drain, I can't figure out why.

Should X use 8-12% CPU for a few minutes with only xterm and htop open, no auto-updated widgets, nothing like that comes to mind..?
Very uncanny, this drain.
