Abstract

Described embodiments provide a local electronic device having a power supply coupled to a power main in wireless communication, via a wireless transceiver, to a remote device. The local electronic device includes a charging station to recharge a rechargeable power supply of the remote devices. The local electronic device detects when at least one remote device is being recharged by the charging station. Based on the detection, the local electronic device selectively enters a low-power mode by disabling one or more circuits to reduce power consumption.
