That is really sad. I used to push four hours with my (very cheap low end model from 2009 keep in mind) HP DV4-1225DX while internetting on a new high capacity battery, and that had a terribly wasteful AMD CPU. IDK what my Thinkpad T510(from 2010 or something mind you) would do with a new battery and I never actually got around to timing the life of it's worn one but I am pretty sure I am still getting around four hours with the same sort of use as DV4. (both using the same Intel 330 240GB SSD and Intel 7260 AC wifi card)Of course DV4's batt started taking a turn for the worse when I replaced it as primary portable so that only lasted a bit over four years.
There are new computers that can legitimately run for more than a few hours on a new battery, so please do not judge modern computers based on an old MBA.
