About my batterry measure bug.
It seems some nokia stuff (or were it CSSU?) couldn't read batterry info while charging behaves properly, and bnf was not fooled by this bug.
Both default statusbar widget and custom desktop widget which is set to mimic original batterry meter shows almost empty (the second is supposed to get more detailed info and is showing 5mAh since i felt asleep).
Bnf seems to read batterry info most directly and instantly and shows that overnight it discharged from about 400mAh to about 300mAh, and now is saying properly charging while the charger is connected.
It also seems bme is not fooled enough to force shutdown. It got 40 celsius now while charging.

I really should test my device with powertop... What was proper command to redirect powertop result to file (it would be easier to copy here, and I'm confused with 4 different "send to file" operators in linux shell... Anyway I'm too lazy to rewrite and prefer copy the info by the device)?
