ive been using mine PRIMARILY since i got it a week ago, for web surfing. Not too many videos...just 1 or 2, 2-3min vids. and reading webpage. doing this on 50% brightness or lower, i get about 5.5 hours. Which obviously drops if i do anything more than just browsing. Can anyone chime in here? ive seen just about every review state about 7.5 hours doing just about same thing. And 5.5 using the dGPU here and there on medium browsing.
