Abstract: A power management method for an electronic device is provided. The electronic device includes a processing unit with a core and configured to execute an application program and a functional element. The power management method includes the following steps: determining a maximum frame count per second of a scene; down-tuning a frequency setting value of the core; detecting an actual frame count per second of the scene; determining a change in power consumption of the processing unit and a temperature of the functional element when the actual frame count per second is equal to the maximum frame count per second; and down-tuning the frequency setting value when the power consumption does not increase and the temperature is lower than a preset temperature value, and restoring the frequency setting value when the power consumption increases or the temperature is higher than or equal to the preset temperature value.

Abstract: A heat dissipation control method applicable to a portable electronic device is provided. The portable electronic device is adapted to mount a heat dissipation back clip, and the heat dissipation back clip includes a cooling chip and a heat dissipation fan. The cooling chip has an adjustable cooling power consumption, and the heat dissipation fan has a heat removal wattage. The heat dissipation control method includes: detecting a real-time system power consumption of the portable electronic device; obtaining the cooling power consumption and the heat removal wattage; determining whether a sum of the real-time system power consumption and the cooling power consumption is greater than the heat removal wattage; and lowering the cooling power consumption if the sum is greater than the heat removal wattage. An electronic device and a portable electronic device to which the heat dissipation control method is applicable are further provided.
