Regular charging
1 Connect the charger to a wall outlet.
2 Connect the charger to the device. The charging
indicator light next to the USB connector is lit when
the battery is being charged.
3 When the device indicates a full charge, disconnect the
charger from the device, then from the wall outlet.
You do not need to charge the battery for a specific length
of time, and you can use the device while it is charging. If
the battery is completely discharged, it may take several
minutes before the charging indicator appears on the
display or before any calls can be made.
Tip: Disconnect the charger from the wall outlet when the
charger is not in use. A charger that is connected to the
outlet consumes power even when it is not connected to
the device.
USB charging
You can use USB charging when a wall outlet is not
available. With USB charging, you can also transfer data
while charging the device.

1 Connect a compatible USB device to your device using
a compatible USB cable.
The efficiency of USB charging varies significantly. In
some cases, it may take a very long time for charging
to start and the device to start functioning.
2 If your device is switched on, you can select from the
available USB mode options on the display of the
device.
Headset
You can connect a compatible headset or compatible
headphones to your device. You may need to select the
cable mode.
Some headsets come in two parts, a remote control unit
and headphones. A remote control unit has a microphone
and keys to answer or end a phone call, adjust the volume,
and play music or video files. To use the headphones with
a remote control unit, connect the unit to the Nokia AV
Connector in the device, then connect the headphones to
the unit.
