2. When the battery is full, fi rst unplug the USB cable from your
phone, then from the computer.
Charge with a wireless charger
Your phone supports Qi, the global standard for wireless charging, and
is compatible with any Qi wireless charger. The charging areas on the
phone and the charger need to touch, so all phone models may not fi t
all chargers.
In order to charge wirelessly, NFC must be enabled on your phone, and a
compatible wireless charging pad (sold separately) is needed.
The charging area is highlighted.
For more information on wireless charging, see the user guide of your
wireless charger.
