To maximise the life of your Oculus for Business headset's internal battery, we recommend that you fully power down the device when it's not in use. This is especially important if you'll be traveling with the Quest, or carrying it in a bag or a case for a period of time.
To power off your Oculus for Business headset and preserve the battery:
Hold the power button for three seconds until a menu appears in your headset.
Select Shut Down from the menu.
This will ensure that the device isn't accidentally turned back to full power mode by accidentally touching the power button, or from the device falsely detecting that it's been placed on someone's head for use.
We also recommend only charging your headset with the charger that was included in the box and avoiding charging your headset when it's in use.
