Abstract
Electronic apparatuses according to embodiments of the present technology may include an electronic device a first surface and a second surface opposite the first. The electronic device may include a battery and a wireless charging coil within an interior volume of the device. The electronic device may include a first magnetic conductor and positioned between the battery and the wireless charging coil. The electronic device may also include an integrated circuit coupled with the battery and the wireless charging coil. The apparatuses may include a case extending about the electronic device. The case may be characterized by a first surface and a second surface. The case may be characterized by a thickness between the first surface of the case and the second surface of the case. The case may include a second magnetic conductor incorporated within the thickness of the case at the second surface of the case.
