  • Wireless charging at substantially uniform charge rate for different physical charge configurations
    Patent number: 12444980
    Abstract: A wireless charging system for a planar wireless accessory includes a receiving coil positioned within the planar wireless accessory and a transmitting coil positioned within a planar electronic device. The transmitting coil generates a magnetic flux that is received by the receiving coil to charge a battery of the planar wireless accessory when the planar wireless accessory is positioned relative to the planar electronic device according to a select charging configuration of multiple user-selectable charging configurations. The transmitting coil and the receiving coil are shaped and positioned to charge the battery at a substantially uniform rate at each different one of the multiple user-selectable charging configurations.
