1. A system, including a first electronic device and a second electronic device, comprising:
the first electronic device comprising:
a first wireless power circuitry, including a first coil, for wirelessly providing power to the second electronic device to charge a battery of the second electronic device, based on detecting that the second electronic device is positioned with respect to a specified portion of a housing of the first electronic device,
wherein the first electronic device is configured to:
identify a battery state and a connection state of the second electronic device based on at least one signal received from the second electronic device, and
visually provide information on the battery state and information on the connection state of the second electronic device; and
the second electronic device comprising:
the battery,
a second wireless power circuitry, including a second coil and resonance circuitry, for receiving a resonance frequency signal corresponding to the power wirelessly provided from the first electronic device to charge the battery,
a first voltage detector configured to detect a voltage of a first signal corresponding to the resonance frequency signal received by the second wireless power circuitry, the first signal being provided to charge the battery when the voltage of the first signal is within a first predetermined range,
a second voltage detector configured to detect a voltage of the battery, wherein power is provided to an electronic circuit chip, including Bluetooth Low Energy (BLE) communication circuitry, for booting the second electronic device when the voltage of the battery is within a second predetermined range and the BLE communication circuitry is in an inactivated state, and
the BLE communication circuitry configured to:
transmit an advertising message for a short-range wireless communication connection based on the BLE communication circuitry being activated, and
establish the short-range wireless communication connection in association with the advertising message,
wherein the second electronic device is configured to:
identify that the second electronic device is positioned with respect to the specified portion of the housing of the first electronic device, based on the resonance frequency signal corresponding to the power wirelessly provided from the first electronic device to charge the battery, and
transmit a second signal associated with sensor circuitry of the second electronic device using the short-range wireless communication connection, and
wherein the sensor circuitry comprises motion sensor circuitry, temperature sensor circuitry, and biometric sensor circuitry.
