Last year I bought a macbook air, today, after 4 months of not using it i upgraded to mavericks and i'm noticing now (with 75% battery) and just web browsing is giving me 3hours of battery life..
to me it seems not that much, i checked the apple page (of the new one) and it says 9 hours for web browsing in wifi
