Microsoft’s HoloLens battery life revealed – and it’s not great



Augmented reality is undoubtedly exciting, even if it only works in short bursts…

The Microsoft HoloLens headset’s battery life has seemingly been exposed, and it’s not great.

According to a video from a HoloLens event in Tel Aviv, the headset will only manage 2.5 hours of power usage.

That’s according to Bruce Harris, a Micrsofot Technical Evangelist, who revealed the details in a video that has now been taken down.

Harris also noted that the HoloLens will generally offer around 5.5 hours of battery life during average use.

The battery life might seem a little lacklustre, but don’t forget that the headset is wireless, and supports both Bluetooth and Wi-Fi connections.

Microsoft has thus far been cagey about revealing specific details on the HoloLen’s battery life, likely due to the fact that the headset is still being tested.

It’s also not clear when the device will become commercially available, or how much it will cost.

Whatever the case, Microsoft HoloLens will be up against plenty of competition, as a number of virtual reality headsets from major manufacturers are poised for release in 2016.

Are you disappointed by the HoloLens battery life, or is it what you expected? Let us know in the comments.

Seems like a non-issue to me, as I'm pretty sure Hololens or any other VR tech isn't going to be something you'll want to wear all day anyway. Motion sickness probably kick in with prolonged use.

Not great according to who? It's a million times better than any of the competition that has ZERO battery life and has to stay tethered ALL of the time. Also for the record, hololens is NOT a VR headset, it's AR.

According to Trusted Reviews. They generally have a grudge against Microsoft. Not sure why, but their articles are always snarky when it comes to Microsoft products.

Yeah that's very true. They also often omit information.

Once microsoft release the revised model in 2017, rather than this prototype, then I am certain they will get the battery life up by an hour or two. These devices clearly aren't ready for primetime just yet. Microsoft are jumping the gun a bit, but they clearly want to be first in on the game. The question is, is there really a big market out there for these type of devices and can you get people used to putting something on their heads and over their eyes, apart from a bunch of techie-loons?

About the same time as the average laptop.

N.b. I said laptop not ultrabook :D

The fact that this article pits an AR headset amongst VR headsets (with no clarification) makes me disappointed really. This isn't the TR I used to read

I don't trust anything said on this site.

2.5hr I'd have said was very impressive for a first generation augmented reality with no wires. Amazing in fact. if they can make the batteries removable even better.

Maybe with VR but AR I can't see there being an issue with motion sickness as you can see your surroundings. Not that I think 2.5Hr is an issue anyway.

we need a huge scientific discovery for battery power, everything lacks because of this. Mobile phones that last one day is simply not good enough at this stage.

Mobile phones last for ages. Mobil computers that just happen to take calls last a day ;-) and has only been brought about by massive gains in battery power and saving over the last few years.
