US Patent 9459710 Method and device for charging stylus

Systems, methods, and devices for charging a power source/battery of a stylus device through a conductive tip of the stylus device are disclosed. Voltage may be input into the stylus device through the conductive tip and applied to a rechargeable battery. This may be accomplished using a charging component, such as, a charging station or dock, including a corresponding electrical contact that interacts with the conductive tip to charge the battery of the stylus device. In this aspect, the stylus device may be configured to recognize when the stylus device is in the charging component and configure itself into a tip charging mode to receive voltage and charge the battery.
