Toshiba says its new Kira Ultrabook packs a ridonkulous 22 hour battery life

What does "all-day charge" mean? For most devices, "all-day" means "all work day," or about 8 hours. But Toshiba just announced a laptop in Japan that's only getting started when your work day ends: The company claims its Dynabook Kira V634/27K gets a jaw-dropping 22 hours of battery life.

Now, there are some caveats attached to that figure. Manufacturer-supplied estimates are often a bit, well, generous, and only achieved under super-optimal conditions. And the Dynabook Kira V634/27K foregoes some of the niceties of modern PCs in order to hit that lofty endurance; the 13.3-inch, 1366-by-768 display is neither super-high definition nor touch-enabled, both of which are features that take a big toll on battery life. Moving up to a more expensive Dynabook Kira with a 2560-by-1440 display and a touchscreen, for example, drops the laptop's lifespan to a (still impressive) 14 hours.

Ready for the bad news? When the long-lasting Dynabook Kira V634/27K launches tomorrow, it'll only do so in Japan. But hey, if Toshiba can pull off endurance like that in the land of the rising sun, PC makers should be able to port it elsewhere just as easily—though it seems the laptop's extreme portability comes at a big price.

The Dynabook Kira V634/27K costs a princely $1450(ish), ho-hum screen and all. But like the hi-res Kirabook that Toshiba released Stateside earlier this year, these new Dynabooks sport slick magnesium alloy-clad cases and other high-end features appropriate for such pricey PCs.
