Samsung's Chromebook had about the same battery life, if not a bit bigger, and achieved that with I think half the battery size. So whatever is going on now, is probably HP or Google's fault. Also, I think you're confusing things. Are you referring to this? http://anandtech.com/show/7085/the-2013-macbook-air-review-13inch/6 http://anandtech.com/show/7085/the-2013-macbook-air-review-1... That shows 11 hours in "light workload". Unfortunately, starting with this year, Apple stopped giving "real" numbers for its Macbook battery life, and started giving battery life for "minimum workloads" like the whole laptop industry has done for more than a decade. The "real" battery life is closer to that "medium workload" (Haswell gave about a 50 percent boost compared to last year's Macbooks). With medium workload, it's 9 hours, with a 50Whr battery (according to you, I didn't check), so at 30Whr, that would normalize it at around 6.7 hours. Still good, but nowhere as impressive as you made it sound at first. I'll grant you this. The decision to use a last-gen chip in this Chromebook wasn't a very smart one, and that's probably HP's fault. Mediocre companies like HP with mediocre employees and mediocre middle management tend to be very slow about adopting new technologies in their products, which is why you never see them come out with some cutting edge tech first.
