Battery issues on my nr70v

[PDASROCK]

I have been having some rather bad battery life on my nr70v, I need to charge it every day at least. I was wondering if anyone has any ideas on what to do about this? I have some underclocking software, and keep the brightness on the lowest setting. Anyone know what in particular drains the batterry the most, and how to avoid it? I'm going to charge mine all the way, then leave it on, and see exactly how long it lasts. Cheers

Me also facing the same problem... It drain out fast, If i play the game continuous half an hours, It took me 50% life of the battery. Anyone can advise us how to do? Or this is the battery defect?:(
