I have my Vario Rct715 paired with my Samsung phone and Edge 830. My problem is I can't get the device fully charged. In both my phone and Edge it shows half charged. I have tried charging the Varia on several different USB-C cables and chargers with the same result. The green light on the Varia shows solid green indicating a full charge. The battery life is commensurate with a half-charge as it lasts about 2.5 hours.
Do I have a defective Varia?
