Uuh... headache on at my end here. Reason why: I use a slightly modified ideal-profile, I made it go from 250MHz to 1GHz, thats all. But I suffer severe battery drain. About 1% per minute!
If I close all apps, let the device rest, and have a look at Conky, the device idles at 250MHz with about 3-5% load on the CPU and all 8-10 secs it upscales to 1000MHz for 2-4 secs with CPU load still around 4% and then back to 250MHz.
I dont have any special background daemons, watchdogs or services running. All apps closed. Where does that jumpy behavior come from?! Conkys graph also is completely level, no peaks or exceptional stress, just upscale to 1GHz and back again.... Any ideas?

the upscaling from 250 MHz to 1GHz for 8-10 or quicker is normal, that is because of the "ondemand" setting of the CPU (not really sure but that is what i read).
Ondemand gives the cpu to switch from the lowest available freq to the highest without scaling on other mid freqs. i believe.

I got annoyed and traded a good nights sleep for a complete reflash. My device is so to say factory new, I just put it back in ops. If its a hardware issue, it should pop up üretty soon again, if it was software, I guess I (dis)solved it.
I guess it would have been fun to track it down...

just to share this:
for almost 5 months (i think its really that long) of overclocking, my experience with battery life is awesome!
in nokia's stock kernel of 250-600mhz, my n900 lasts up to 8hrs - 10hrs of stand-by with wifi and 5 IM accounts, and i think 2 hrs of web browsing plus video streaming.
when i overclocked using enhance kernel for power users, with the Ideal settings of 500-850mhz up to 1150mhz, stand-by (with all activites same as above) lasts for 13hrs-15hrs between charging/replace battery!
EDIT: i just looked at Conky and my uptime is 16hrs, 48mins and 3secs.

I think i found a bug...
When i set the custom voltage profile Min freq 125 and Max 256.
While using it i see cpu frequency going upto 500 everytime and keep jumping from 125 to 500. Otherwise if i fix other frequencies it follows the command properly.
Any suggestion how to avoid 500
I am checking the minimum voltage tolerable.

i always stay @500-1.15GHz (ideal) settings as my personal settings and let it load upon every boot, but no extra-ordinary battery drain.
the upscaling from 250 MHz to 1GHz for 8-10 or quicker is normal, that is because of the "ondemand" setting of the CPU (not really sure but that is what i read).
Ondemand gives the cpu to switch from the lowest available freq to the highest without scaling on other mid freqs. i believe.
check your cpu usage again, you might have instances that your cpu runs constant @ 100%
if i did help you, just click "Thanks" on the lower right of my post. thanks!
