Charge the battery
Your battery has been partially charged at the factory. If the device indicates a low charge, do the following:
Connect the charger to a wall outlet.
Connect the charger plug to the device.
If you are using a USB charger, connect the charger plug to the USB connector.
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.
Charging with the USB data cable
Charging with the USB data cable is slower than charging with the charger. Charging with the USB data cable may not work if you use a USB hub. USB hubs may be incompatible for charging a USB device.
When the USB data cable is connected, you can transfer data at the same time as charging.
Connect a compatible USB device to your device using a compatible USB data cable.
Depending on the type of the device that is used for charging, it may take a while for charging to start.
If the device is switched on, select from the available USB modes.
