All this could be easily debugged with powertop. If someone would have made dead simple battery discharge program that logs power,dmesg etc couple of times in minute to file wich can be send to webpage which draws lines for consumption and battery level and shows what was happening then from logs. Also some icon to system area which changes from green->yellow->red by current discharge level.

It just makes me wonder why these have not been yet fully implemented because they would be really really good debuggin tools for average users. And because of that developers would get huge amount information about what program sucks *** and what kicks it.

There is some little bits in wiki saying that people testing extras should look how much program uses battery but i cannot find dead simple guide how to setup system and how to analyze logs.
