If the LG X Power will not power on or show any sign of charge unless it is plugged, you will need to try to exchange the battery for a new battery. This may be caused by overuse or leaving it charging too long.
Turn the phone off. Press and hold the following keys at the same time: Volume Down Key + Power/Lock Key on the back of the phone. Release the Power/Lock Key only when the LG logo is displayed, then immediately press and hold the Power/Lock Key again. Release all keys when the Factory hard reset screen is displayed.
