>Charge your HoloLens
Connect the power supply to the charging port by using the USB-C cable (included). Plug the power supply into a power outlet. The power supply and USB-C-to-C cable that come with the device are the best way to charge your HoloLens 2. The charger supplies 18W of power (9V at 2A). Using the wall charger supplied, HoloLens 2 devices can charge the battery to full in less than 65 minutes when the device is in standby.
Charging rate and speed may vary depending on the environment in which the device is running.
When the device is charging, the battery indicator lights up to indicate the current level of charge. The last light will fade in and out to indicate active charging.
When your HoloLens is on, the battery indicator displays the battery level in increments.
When only one of the five lights is on, the battery level is below 20 percent.
If the battery level is critically low and you try to turn on the device, one light will blink briefly, then go out.
Full details on device charging can be read here if more information is needed.

>Running VIRNECT View In HoloLens 2
The HoloLens 2 reduces 5% just in standby mode for an hour. While use the VIRNECT View for a while and just wear the HoloLens without any functioning it reduces 10% for an hour which means 60 minutes it’s taking 10% charge. And for running View and going through the content while giving break for while for the HoloLens(without wear) / keep somewhere its consideration reduces between 92% to 95% for an hour. But if continuously use the VIRNECT View software without break or standby mode, it will take and reduce 1% to 2% charge for every 1 minutes. It means the battery life reduces faster when we use it without rest.
HoloLens 2 battery life can hold for 10 hours if not using much while running with VIRNECT View and keep on standby mode and also giving rest for the HoloLens. But if the HoloLens keeps running without standby mode or VIRNECT View continuously running the battery life can only hold for 2 hours or 2 and 15 minutes maximum.
*More important is once the HoloLens battery life reaches 5%, it shuts down itself. You need to charge the HoloLens 2 to use it again.
>Battery Life Using External Power Bank 10k mAh
External Power bank battery life can hold for 10 hours if not used much while running with VIRNECT View and keep on standby mode and also giving rest connected with HoloLens. But if the Power Bank keeps running without standby mode or VIRNECT View continuously running on the HoloLens 2, the Power Bank battery life can only hold for 5 hours 30 minutes maximum. But the battery life of HoloLens 2 still remains 100%, meaning fully charged.
>Running VIRNECT Remote In HoloLens 2
*Note
Same account cannot log in to different other device’s at the same time. You only have permission for one account to log in one device at the same time.
Maximum Recording time the REMOTE live streaming 60 - 120minutes.
You only can screen record by handling browser Remote, in HoloLens 2 need use Microsoft Home screen record.
The open season you created can be used more than once. “Just by click Restart”
Can create the season based on Browser, Phone, and Tablet but one device only has permission to log in at the same time.
Can zoom image the collaboards in HoloLens 2 by Air Tap by two hands and zoom in & out. 50% to 200% you can zoom in the image in collaboards.
The HoloLens 2 reduces 15% for every 20 minutes while using the VIRNECT Remote app continuously. It means the HoloLens 2 battery life is 100% to 5% reduced within 2 hours or 2 hours 15 minutes maximum with default battery life by running the VIRNECT Remote continuously.
With Power Bank
90 minutes - 100% in HoloLens 2 ( 4 lights turn to 3 lights )
75 minutes later the HoloLens 2 battery life still remains the same 100% and in the power bank 10k mAh changed 4 lights to 3 lights. It still remains the same output while tested again.
>Comparison VIRNECT View & VIRNECT Remote - HoloLens 2 Battery Life.
The conclusion is that both apps maintain almost the same battery life while running on the default battery. If running VIRNECT View it took almost 2hrs to shut down itself on the default battery , for the VIRNECT Remote almost 1hrs 50min to 2 hrs to shut down itself on the default battery. And for the power bank testing VIRNECT View holding 5hrs 30min maximum , HoloLens battery life remains 100%. For the testing VIRNECT Remote with power bank 10k mAh, its holding 5hrs maximum, HoloLens battery life remains 100%. Because it covers the system running live streaming by HoloLens to PC. So if you use one power bank of 10k mAh, 1 unit (HoloLens 2) can be used for up to 5-6 hours in a day, even VIRNECT View and VIRNECT Remote.
We suggest buy at least external power banks which are 10k mAh or 20k mAh.
But the cable always connects with HoloLens, the power bank must be ON. More information.
