Good point from Alex Chitu at the (unaffiliated with Google) Google Operating System blog:
It’s not clear why the latest Chromebooks no longer have a great
battery life, but the new batteries are obviously cheaper and
lighter. Google’s Chromebook features page no longer mentions the
word “battery”, even if this was one of the main selling points
for the first Chromebooks.
This was posted before Google announced their own $1299 Chromebook Pixel hardware, but even that doesn’t fare well. Google claims “up to 5 hours of active use”; both the 13-inch MacBook Air and 13-inch MacBook Pro With Retina Display promise “Up to 7 hours wireless web”.
Battery life is one reason why I remain a deep skeptic of Chrome OS. Post-PC devices should get better battery life, not worse.
