Abstract: A method of an electronic device are provided in which current consumption for one or more components of the electronic device is compared with a predetermined current. A first surface temperature of the electronic device is determined based on the comparison and power consumption of the one or more components. A location is detected where heat corresponding to the first surface temperature is generated. A second surface temperature of the electronic device is obtained based on power consumption of a component disposed in the electronic device corresponding to the location where the heat is generated. A target temperature is set based on the obtained second surface temperature. The component is controlled to reduce the power consumption of the component based on the target temperature.

Abstract: An electronic device is provided. The electronic device includes a battery, a power management module, a charging circuit, and a processor including a central processing unit (CPU) and a plurality of intellectual property (IP) blocks. The charging circuit is connected to the processor and includes a first pin to output a first overcurrent warning signal. The power management module is connected to the processor and includes a second pin to output a reset warning signal. The processor includes a first general purpose input output (GPIO) pin to receive the first overcurrent warning signal, and is configured to reduce at least one clock frequency among a plurality of clock frequencies set to each of the CPU and the plurality of IP blocks, or reduce at least one operation clock frequency of components inside the electronic device when the first overcurrent warning signal is received through the first GPIO pin.
