Toshiba KIRAbook High Resolution Ultrabook
Battery Life

The KIRAbook’s performance here was fairly impressive, though under load the machine can chew through a battery charge quickly. As we’ve mentioned earlier, the system’s price demands serious performance, and Battery Eater Pro ate up the KIRAbook in a mere 112 minutes. Battery Eater Pro puts the ultrabook’s resources to work (the KIRAbook’s fan was noticeable the entire time), but plenty of systems offer more than two hours of battery life in the BEP test. Then again, those systems likely don't offer the performance of the KIRAbook either.
When we ran our Web test, however, we saw the best results we’ve seen from an ultrabook so far. The KIRAbook refreshed a webpage for a total of 7 hours and 28 minutes – beating out HP’s Envy ultrabook, by three minutes. If your usage patterns are fairly light, the KIRAbook will see you through long excursions. If you find yourself needing extra CPU cycles for multimedia work or other things like image processing be prepared to tether back up to the wall. In reality, performance when you need it and battery life when you don't could be considered the best of both worlds, again, depending on you usage model.
