HP Pavilion DV6-1354US 15.6-Inch Black Laptop - Up to 4 Hours of Battery Life...?

Yea dude, i have Pavillion DV7 Quad core. My battery life depends on what im doing. Playing a Bluray or DVD is going to require more processor power and more battery. If im simply taking notes in cl my battery will last about 5 hrs. Also, HP has a power management feature that will reduce battery consumption. You can choose how much processor power, screen brihgtness etc you use to further extend your battery.
