Microsoft's HoloLens augmented-reality glasses will offer between 2.5 and 5.5 hours of battery life, according to a technical evangelist working for the company.


A YouTube video of a presentation by Microsoft Technical Evangelist Bruce Harris in Tel Aviv (which has since been removed) included information on the HoloLens' battery life and intra-device connectivity. (Thanks to Petri's Brad Sams for the information from the video.)

Updated: The Verge's Tom Warren has posted the Bruce Harris video clip to YouTube.

As Microsoft officials have said previously, the HoloLens will be an untethered Windows 10 computing device. Harris told his audience that anything that supports Wifi or Bluetooth will be able to connect to the HoloLens.

In normal usage situations, the HoloLens battery can run up to 5.5 hours, Harris is said to have revealed, but under heavy usage, that number drops to 2.5 hours.

According to Sams' write-up, Harris also acknowledged that the HoloLens' field of view sis similar to what users would see using a 15-inch monitor about two feet away. As manufacturing improves, resulting in better battery life and lower prices, that field of view will expand, Harris said.

Harris also described a way to link HoloLens devices together to view an object simultaneously by sharing a link over the Internet even if those users are not in the same room.

Microsoft recently opened a HoloLens showcase for developers in its New York City flagship retail store.

This month, Microsoft officials have said that developers in U.S. and Canada will be able to sign up to request access to HoloLens developer kits, which will be $3,000 a piece, with a limit of two per developer. Those kits will go out to those selected during the first quarter of 2016. There's no public information at this point as to what's included in the kits.

Microsoft's HoloLens is an augmented-reality headset that Microsoft is hoping will be used in both business and consumer settings. Microsoft's first target audiences for HoloLens are developers and business customers.

HoloLens is one of the Microsoft device platforms that run Windows 10 at its core, meaning developers can target the HoloLens with their Universal Windows Platform apps.
