Anyone having idea what will be the battery life for a Dell Studio 15 core i7 720 with a 6-cell and 9-cell battery?
I dont like the 9-cell sticking out of the laptop. But with the processing that comes with i7 720 will a 6 cell provide decent battery life?
LaptopMag.com did a review of the Studio 17, which is the big brother to the one you are looking at, with an i7 720 and an HD 4650. They got about 3.5 hours while web surfing on the 9-cell battery. It may give you an idea of what to expect. See the second graph here:
