CPU usage when making a call is valid. I meant pulseaudio constantly taking
approx. 2-5% CPU time when device is completely idle, even with screen off.
Oh, found it: https://bugs.maemo.org/show_bug.cgi?id=6868

As Michel pointed - there was a typo, I should say 'tonegend'.

It helps finding which usage patterns are the most battery-hungry and gives
indication of some dodgy background action (like tonegend above) eating
battery when device is supposedly "idle". But that's only my personal
preference, I guess.

All in all, I definitely concur that one of N900's worst gripes is power
management (or lack of thereof) and getting out without a charger at hand
for more than 1 day should be considered a crime. ;)
