With all the VR hype that’s going around right now, it’s easy to forget that honestly this generation of VR headsets is only just beginning. No matter how excited we are for them, there are going to be things that they could do a lot better.

Case in point, a presentation delivered by Microsoft’s Bruce Harris from the Tel Aviv business event about their upcoming Hololens suggested that its battery life really isn’t going to be that long. It’s going to have one of just 5.5 hours, but that’s only if you’re doing things like reading e-mail or messing around with Word documents. With more “intensive use” the battery will only last an estimated 2.5 hours. That includes all the 3D demonstrations of the headset’s use that Microsoft has been using as their big wow factor at events.

There was a recording of the presentation up on Youtube earlier, but it’s already been taken down. Still, it’s interesting information to have because the HoloLens is not one of the headsets we’ve had a lot of details about so far. Harris also pointed out that the device has “no option for a wired connection” so it seems that you can’t even choose to charge it up while you use it.

Given that the HoloLens doesn’t have a wired connection option and again the fact that VR tech is only just taking off right now, its short battery life is not really an unexpected thing. It just feels a little bit limiting that the really cool stuff can only be played with for so long before you need to recharge it.
