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.

Abstract: Various embodiments of the disclosure relate to an apparatus and method for preventing overcharging of a battery. In this case, the electronic device includes a battery, at least one processor, and a memory electrically coupled to the at least one processor. The memory may store instructions, when executed, allowing the at least one processor to set a charge safety time corresponding to an external device upon connection with the external power device, charge the battery, based at least in part on power of the external power device, and update the charge safety time, based on a change of at least one of charging current and discharging current of the battery. Other embodiments may also be possible.

Abstract: An electronic device is provided. The electronic device includes a housing, a power interface exposed through at least a portion of the housing to be connected to an external power source in a wired manner or disposed inside the housing to be connected to the external power source in a wireless manner, at least one battery disposed inside the housing and electrically connected to the power interface, a processor disposed inside the housing and operatively connected to the power interface, and a memory disposed inside the housing and operatively connected to the processor. The memory stores instructions that, when executed, causes the processor to, in a state in which an external power is supplied through the power interface, when a voltage of the battery reaches a first voltage value, lower the voltage of the battery to a second voltage value lower than the first voltage value by discharging the battery after a first time has elapsed from a time point at which the voltage of the battery reaches the first voltage value.

Abstract: An electronic device is provided. The electronic device includes a housing, a first battery and a second battery arranged in the housing, a power management module, a first temperature sensor, a second temperature sensor, a first current limiting integrated circuit (IC) configured to limit a maximum intensity of a first current flowing into the first battery, a second current limiting IC configured to limit a maximum intensity of a second current flowing into the second battery, and a processor. The processor may determine whether the first temperature or the second temperature is outside a specified temperature range and, when the first temperature is outside of the specified temperature range, control the first current limiting IC to reduce a magnitude of the first current.
