Hello and thanks for reaching out!
Make sure you are using the original battery and charging accessories that came with your phone, as our devices work best that way. Try taking out the battery for about 2 minutes to soft reset your phone. If the problem persists, you might want to try a factory reset, AFTER backing up your personal data. http://bit.ly/MBvs0N
