Getting started
•
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
recognise your head movements.
–
If the Gear VR is not used while the charger is
connected, the mobile device's battery will be
charged.
