Power down when not in use
To maximize the life of your internal battery, we recommend that you fully power-down, or turn off, the device when it's not in use, rather than just putting it to sleep. This is especially important if you'll be traveling with your Quest 2 or Quest, or carrying it in a bag or a case.
To turn your headset off, hold the power until the indicator light
on the front of the headset turns off, and the power down chime is played.
This will ensure that the device isn't accidentally turned on by either jostling the power button, or from the device falsely detecting that it's been placed on someone's head for use.
about the difference between turning your headset off vs putting it to sleep.
Unplug when fully charged
Leaving your Quest 2 or Quest on the charger after it has been fully charged can reduce the overall battery life over time. When your headset is finished charging, the indicator light on the side of the headset will go from red to green. When this happens, unplug your headset. If you aren’t planning to use your headset after charging, power it off after unplugging.
Use the provided charger
When charging your Quest 2 or Quest, use the charger that was included in the box. While you may be able to charge your headset’s battery with chargers from other devices, your headset and its included charger were designed and tested to work optimally together and to maximize the performance of your headset.
Please note, if you’re having trouble getting your Quest 2 or Quest charger to fit correctly in a wall outlet, you may need to adjust the position of the grounding pin.
