Chromebooks are set to get a big kick up the rear when it comes to battery life. Intel Haswell-based Chromebooks were announced today at the Intel Developers Forum 2013, promising 50 per cent battery life improvement over current-generation models. That's an apparent 9-10 hours of use per charge.

More manufacturers are joining the Chrome fold too: in addition to the second-gen HP Pavilion Chromebook 14 and new Asus Chromebox shown off on stage in San Francisco, a Toshiba Chromebook was also unveiled.

Caesar Sengupta, product management director of Chromebooks, explained in a blog post that the Haswell-based Chromebooks will launch "over the coming months" from multiple device manufacturers like Acer, HP, ASUS and Toshiba.

Aside from the HP Chromebook 14, Toshiba Chromebook and ASUS Chromebox, Sengupta said a "light and portable" Acer Chromebook is on the way. All models are due in Q4 in advance of the Christmas holiday period.

HP detailed its Chromebook 14 even further after the Intel event. Past a Haswell chip, it features a 14-inch display, 16GB SSD, HDMI, USB 2.0, USB 3.0, microphone jack, and 4G. It will be available for $299 in the US before Christmas. 

We might not be the biggest fans of Chromebook as a whole - the concept is good, the reality of it less readily usable - the low-cost, low-power-consumption Google-OS-based devices certainly shift in volume. And the Haswell-based platform ought to push the popularity up yet further.
