Your battery has been partially charged at the factory, but you may need to recharge it before you can switch on your phone for the first time.

  1. If your phone needs recharging, do the following:

    First plug the charger into a wall outlet, then connect the cable to the micro-USB connector in your phone. With the front of the phone facing you, the micro-USB connector is, from left to right on the top edge, the second item.
  2. When the battery is full, do the following:

    Unplug the charger from the phone, then from the wall outlet.

You can use USB charging when a wall outlet is not available. Data can be transferred while charging the device. The efficiency of USB charging power varies significantly, and it may take a long time for charging to start and the device to start functioning.

You do not need to charge the battery for a specific length of time, and you can use the phone while it is charging.

If the battery is completely discharged, it may take several minutes before the charging indicator is displayed or before any calls can be made.

If the battery has not been used for a long time, to begin charging, you may need to connect the charger, then disconnect and reconnect it.
