Maybe I wanting too much of a 4 cell battery, but is a little bit stranger that sometimes the battery lifetime is near to a 2 hours in a $1600 machine. I saw in the internet some guys saying that your gl502vs can go beyond 5 hours in daily use! Probably that guys have made some kind of fine adjustments.

impossible. read all the press reviews of the 502VS. No one is getting 5 hours from a 65whr battery with no Optimus.
it doesn't matter how many cells a battery has. It's the whr rating that matters, and other laptops have 90whr batteries at the expense of a 2.5" hard drive.
it also doesn't matter how much the computer costs. They just can't fit a 99whr battery into this one to give you 4-5 hours.
If you can undervolt and underclock the cpu and gpu, you can probably squeeze out another 1 hour battery life. You really don't need the full cpu power to do tasks on battery power.
set cpu limit to 1.2ghz, undervolt it by a lot, limit gpu to 500mhz and undervolt, and test.
This should be enough for streaming videos and web browsing.
