Slide your Galaxy S9 into the battery case, lining up the USB connector of your phone with the USB connector of the case.
Press and release the power button located on the back of the case to begin using the 4200 mAH battery built inside of the case. Press and release this power button at anytime to stop using the 4200 mAH battery and begin using your phone's internal battery.
Plug your 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.
