If they are benchmarking at 13+ hours for video playback, why is it hard to believe 18+ hours for normal things like checking email, browsing the web, etc?
20 hours seems to be the norm for me, mostly web browsing and reading magazines. half brightness, etc.
exactly. I charged my last night when it was at 34% and had 14 hours of usage. I'm sure I could have gotten 18 before it totally died.
