Abstract: An electronic device and an operating method thereof for monitoring, identifying and controlling an application and a component which excessively consume battery power are provided. The electronic device monitors an operation of an application installed therein or an operation of a component embedded therein. The electronic device checks the amount of power consumed for the operation of the application or the operation of the component at regular intervals, and based on the checked amount of power, determines whether the operation of the application or the operation of the component is an abnormal operation. If the operation of the application or the operation of the component is an abnormal operation, the electronic device identifies a policy corresponding to the abnormal operation and based on the identified policy, controls the operation of the application or the operation of the component to eliminate the abnormal operation.

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.
