Thanks for the responses guys.
I was not referring to 3-4 hours whilst gaming, but primarily whilst doing almost nothing but note-taking during my lectures. The sales page advertises 10 hours on average. If I can only get a maximum of 4 hours when taking notes, the discrepancy is so huge that I believe the conditions under which the battery was tested must be listed as something different than "on average". Aside from that, I find it very hard to believe that even under the right conditions, the battery manages to get 10 hours at all.
Is there anything you guys can recommend I should do aside from turning on battery-saver and whatnot to maximize my battery potential? I should have specified, but 4 hours is really all I can get with battery-saver turned on. Please note that I have taken your advise into consideration, but is there anything else I can additionally do? Or is there a thread on the forums I can read for tips and steps?
Can you please let us know, where it is advertised with the description 10hrs battery life on average? The wording is indeed inaccurate.
