Microsoft evangelist Bruce Harris gives a few details on the HoloLens augmented reality headset at a Tel Aviv event-- including the fact the device battery lasts for 5.5 hours of regular use. As reported by Petri, "heavy loads" slash battery life to just 2.5 hours.

The power issue also limits the display capabilities of the headset, leading to a field of view "similar" to a 15-inch monitor close to the viewer's face.

Such fact might make the Hololens look limited, but Microsoft does have a few tricks up its sleeve-- the device runs any universal Windows 10 application and is "totally wireless," with no wired option available.

Connectivity comes through wifi and Bluetooth, and the users can pair Hololens headsets together to share AR experiences.

Microsoft is still to provide a Hololens consumer release date, but shipments to developers should start from Q1 2016.
