Electronic device for controlling luminance of display, and operating method and recording medium thereof

A method of operating an electronic device, the method comprising:

• based on a brightness level of a display of the electronic device being set to be a first level based on an ambient light level, based on a temperature of the electronic device identified using at least one sensor of the electronic device reaching a first temperature, identifying a temperature change rate within a designated time period and determining an intermediate temperature between the first temperature and a second temperature higher than the first temperature, for reducing a brightness level of the display to an intermediate brightness level between the first level and a second level less than the first level, wherein based on the temperature change rate being greater than a threshold temperature change rate, the intermediate temperature is set to a first value, and based on the temperature change rate being less than the threshold temperature change rate, the intermediate temperature is set to a second value greater than the first value, based on the identified temperature change rate;
• based on a current temperature of the electronic device reaching the intermediate temperature, reducing the brightness level of the display to the intermediate brightness level;
• and
• based on the current temperature reaching the second temperature, reducing the brightness level of the display to the second level.

A non-transitory computer-readable storage medium storing computer-executable instructions, wherein the computer-executable instructions, when executed by at least one processor including processing circuitry individually or collectively, cause an electronic device to:

• based on a brightness level of a display of the electronic device being set to be a first level based on an ambient light level:
• based on a temperature of the electronic device identified using at least one sensor reaching a first temperature, identify a temperature change rate within a designated time period and determine the intermediate temperature, between the first temperature and a second temperature higher than the first temperature, for reducing brightness level of the display to the intermediate brightness level between the first level and a second level less than the first level, based on the identified temperature change rate, wherein based on the temperature change rate being greater than a threshold temperature change rate, the intermediate temperature is set to a first value and based on the temperature change rate being less than the threshold temperature change rate, the intermediate temperature is set to a second value greater than the first value;
• based on a current temperature of the electronic device reaching the intermediate temperature, reduce the brightness level of the display to the intermediate brightness level;
• and
• based on the current temperature reaching the second temperature, reduce the brightness level of the display to the second level.
