Samsung Gear VR: How do I charge the Gear VR?
The Gear VR does not require charging as it is powered by the mobile device’s battery.
But, You can connect the charger to the charger port on the Gear VR. Use only Samsung-approved USB cables and 2A power adaptors.
–If you use the Gear VR while the charger is connected, it is powered by the charger and does not use the mobile device's battery. When you use content that has high power demand (more than 1A) while the charger is connected, the Gear VR uses two power sources. In high power demand situations, the Gear VR is powered by the charger and the mobile device's battery at the same time.
–If the Gear VR is disconnected from the charger while the Gear VR is being used, the image on the screen may be briefly inactive. During this period, the screen recalibrates and the Gear VR may not recognize your head movements.
–If the Gear VR is not used while the charger is connected, the mobile device's battery will be charged.
