Yes, exactly that way (powertop modus operandi).
Skype running? mmm, it could be, did I forget of unable it? mmm,
Kernel modified? Yes, and charged with the ideal conf. (850-500 MHz if I'm not wrong). Based on related posts, battery shouldn't notice this overclocking (but who knows).

So, I'm looking forward to see your results after you enable similar apps. Meanwhile, I'll do more tests ... but indeed, I'll rather re-flash the device and do the tests, and then install the apps and compare. But I need to be sure that with a flashed device my times are as the ones that are said here.

BTW, I'm not feeling unconfortable. I appreciate very much people giving their time trying to help me. I guess my first posts were coming from a frustration state, that I think I wouldn't have if meego hadn't appeared, and in consequence we would be in PR1.3 version.

I think that the first confussion I did is to think that these forums are from nokia people. Since these aren't, you obsiously don't have any need to hear so many complaints.

Having said that, let's see if I can reproduce the battery times that some of you seem to enjoy

PD: isn't any script that can predicts the time of battery based on the consume during the last minute? As it does my netbook, If I activate the wifi and increase the brightness of the display, I can see how the expected battery time decreases in the prediction.
Does something similar exist in linux?
