    Abstract: An electronic device and method of operating an electronic device are provided. The electronic device includes a temperature measurement unit configured to measure a temperature of each of multiple components of the electronic device, and a controller configured to change, based on a first reference temperature, an operating frequency of the controller to a first operating frequency when a temperature of the controller, measured by the temperature measurement unit, reaches the first reference temperature and change, based on a third reference temperature that is lower than the first reference temperature, the operating frequency of the controller to a second operating frequency when a temperature of at least one component of the multiple components reaches a second reference temperature while the controller operates at the first operating frequency.
