Abstract
A mobile device includes a housing and an antenna. The mobile device further includes a power-receiving circuit, and power-transmitting circuit, and a short-range communications circuit. The antenna performs multiple functions in that it is shared by the power-receiving circuit, the power-transmitting circuit and the short-range communications circuit. Each of the three circuits is selectively connectable to the antenna. The mobile device is configured to participate in a mobile-to-mobile battery-charge-sharing operation via inductive coupling from mobile device to mobile device.
