We also got an early glimpse of battery performance from Intel's incoming Haswell processor: you can expect to glean 10 hours of use in tablet mode, which is on par with many lower-powered tablets already on the market (think: Atom, ARM, et cetera). Factor in a keyboard battery (at least on this reference device) and you can expect an additional three hours of runtime. Unfortunately, there's still no word on when those next-generation low-power chipsets will arrive, although there's plenty of time till the next big PC show, Computex, rolls into Taipei.
