Have you connected it to your phone\
MDE app yet? Once you do that, then you can fully charge it. When the green light goes all the way around, it will be fully charged. The light will not go all the way around until after you pair it. The app will indicate the charge amount; however, it will say fully charged, even if the green light is not all the way around. Just charge it until it is all the way around. When you are not weary it, turn it off by pressing the button on the back until it beeps twice, about 6 seconds. A red light will come on around the circle, and then it will power off.
