How many hours of usage can I expect from the 6 and 9 cell batteries Dell offers with the Studio 15 (for general usage, like wifi browsing and some applications like word)?
Also, if you own a slightly older Studio 15, by how much has the battery capacity decreased over time?
I'm mostly buying the 9 cell, so if you own the Studio 15 with a 9er, please do tell me about it! But 6 cell'ers too answer, because i can then approximate the 9 cell's performance.
