Okay, this is the deak:
I bought a brand new HP Compaq 6720s a couple of months ago. At start it gave me about 3 hours battery runtime while doing office work and 1 and half hour when listening music or watching movies or playing games... At those times i had Hardy heron and everything same as what i have now...
Recently my laptop battery has started to give me real problems. It gives me runtime of about 30-40 minutes even if i don't do anything, with screen brightness as low as possible, with almost all background processes killed... Even compiz disabled...
Even followed this:
