HoloLens has a very short battery life, drawing criticism

Microsoft’s augmented reality glasses can run for only up to 5 hours before they need to be plugged in.

A recent presentation made by Bruce Harris, the Microsoft technical evangelist, in Tel Aviv, revealed several pieces of insight about the augmented reality Hololens headset, some of which impressed the tech industry and some of which is turning out to be a bit of a disappointment.

Though many details had been revealed back in October, this recent presentation offered more insight.

Back in the original demonstration of HoloLens by Microsoft, last October, there was a great deal revealed about the function of the augmented reality device. However, some key factors were absent in that presentation, including battery life, pricing and other additional functionalities. Now, the recent Tel Aviv presentation from Bruce Harris has shown a great deal more of the finer points surrounding this gadget.

Harris explained that, depending on its usage, HoloLens will last only 2.5 to 5.5 hours before needing to recharge.

HoloLens Draws CriticismThis suggests that if anyone were to invest in one of these devices, they may also want to have a good portable charger with them, as well. After all, using the headset for routine activities will give the individual only just over five hours. However, when pushing the device a little bit harder, that battery life can shrink down to 2.5 hours. For that to become a practical device it will need to be used alongside an external battery pack.

Harris also went on to say that HoloLens will be capable of running virtually any Universal app and it is currently operating on Windows 10 out of the box. Also pointed out in the presentation was that when the headset becomes consumer ready, it will be “totally wireless” and will be capable of connecting to any Bluetooth device or WiFi network. Of course, if WiFi drains this device as much as it can take down many smartphones and tablets, this will only reinforce the need for a portable charger that will be able to recharge it a few times each day.

When it comes to field of view, the HoloLens should provide an experience that can be compared to that of a 15 inch monitor. This field of view was selected in order to make it possible for Microsoft to provide optimal production capabilities in order to keep costs manageable.
