To Use:

  1. Slide the top piece of the case up and slide your phone directly into the case, lining up the micro USB connector located at the bottom of the battery case with your phone's micro USB connector. Once your phone is inserted into the case slide down the top piece of the case
  2. Press and hold the power button for a few seconds on the front of the case to use the 3200 mAH battery; press and hold the power button again to turn off the battery from the case and only use your phone's internal battery
  3. Plug your micro USB cable into the bottom of the battery case to recharge both your phone's internal battery and the battery case. To recharge both devices you will need to press and hold the power button located on the battery case to activate the connection between the phone and case after the case has been plugged into a power source. If you simply plug-in the case to a power source without pressing the power button only the case itself will recharge.
