Abstract
An electronic device includes a power management circuit which supplies power from a battery to electronic components, a battery management circuit which controls connection between the battery and the power management circuit, a physical key formed on a part of the electronic device, a key control circuit which controls connection between the physical key and the battery management circuit, and a processor connected to the power management circuit. The processor is configured to transmit a signal for powering off the electronic device to the power management circuit, and when the electronic device is powered off, to control the key control circuit to connect the physical key with the battery management circuit. The power management circuit is configured to, when receiving the signal for powering off the electronic device, control the battery management circuit to disconnect the battery from the one or more electronic components included in the electronic device.
