To dynamically manage a temperature of an electronic device, a local temperature is provided by measuring a temperature of a local spot in the electronic device and a reference temperature is provided by measuring a temperature of a reference spot in the electronic device where the reference spot and the local spot are thermally coupled. A target temperature corresponding to a limit value of the reference temperature is adjusted based on the local temperature and a power level of the electronic device is controlled based on the same target temperature. The target temperature may be set to a relatively high value to secure performance of the electronic device when the local temperature is relatively low. Alternatively, the target temperature may be set to a relatively low value to pursue stability of the electronic device when the local temperature is relatively high.
