Abstract
A protective case includes a shell for receiving and at least partially covering an electronic device. The shell includes a first material and has a back portion and side portions extending from the back portion. The back portion is configured to be adjacent to the back surface of the electronic device when the electronic device is installed. The case also includes a core comprising a second material having a magnetic permeability substantially greater than a magnetic permeability of the first material. The core is affixed to the back portion of the shell at a location that coincides with a center region of the wireless charging coil of the wireless charging circuitry of the installed electronic device. The core increases magnetic coupling between the wireless charging coil of the installed electronic device and a source charging coil when the protective case is placed in proximity to the source charging coil.
