    Abstract: A mobile phone may include a housing structure defining a peripheral wall and a front cover formed of glass and coupled to the housing structure and defining at least a portion of a front exterior surface of the mobile phone. The mobile phone may further include a display below the front cover, a circuit board assembly coupled to the housing structure, and a removable rear cover assembly coupled to the housing structure and including a rear cover formed of glass, a rear-facing camera window, a charging coil coupled to the rear cover and configured to wirelessly receive power for charging the mobile phone, and an electrical connector conductively coupling the rear cover assembly to the circuit board assembly. The mobile phone may further include a supplemental housing component configured to be coupled to the housing structure in place of the removable rear cover assembly.

    Abstract: Embodiments describe a portable electronic device that includes a housing having an interface surface and an inductor coil disposed within the housing and comprising a conductive wire wound in a plurality of turns about a center point and in increasing radii such that the inductor coil is substantially planar. The portable electronic device further includes charging circuitry coupled to the inductor coil and configured to operate the inductor coil to wirelessly receive power and wirelessly transmit power, control circuitry coupled to the charging circuitry and configured to instruct the charging circuitry to operate the inductor coil to wirelessly receive power and to wirelessly transmit power, and a device detection coil coupled to the control circuitry and configured to detect the presence of an external device on the charging surface, the device detection coil is configured to operate at a different frequency from the inductor coil.
