Abstract: An electronic device according to various embodiments may include: a battery, a switch coupling the battery to a main board on which components of the electronic device are disposed, a power management module comprising power management circuitry including a function of powering on the electronic device at a power-on time set to power on the electronic device that is in a power-off state of the electronic device, and a processor. The processor may be configured to: upon identification of a power-off request for the electronic device, set the power-on time and power off the electronic device, based on the electronic device being powered on upon identification of the power-on time, compare a power-off period of the electronic device with a threshold period, and based on the power-off period of the electronic device being longer than a threshold period, decouple the battery from the main board by opening the switch.
