Charging the headset
Plug the headset into the power cable to charge whenever it is not in use for training. If you have an Oculus Go headset, ensure that it is powered on before plugging it in so that the device can receive updates. Pico G2/Pico 4KS/Pico Neo 3 headsets turn on automatically when plugged in. To charge fully from a dead battery takes about two hours, and a fully charged headset will play for two to three hours. You can check the precise battery level percentage in the menu of the headset.
When the indicator light on the headset turns red, the battery is low (below 15% in Oculus Go, below 20% in Pico G2/Pico 4KS/Pico Neo 3).
