Abstract

Disclosed is an operating method of an electronic apparatus. The method includes measuring the load rate of the electronic apparatus that operates at the first driving frequency level. The method also includes determining a second driving frequency level based on the measured load rate. The method further includes determining whether or not to change the first driving frequency level into the second driving frequency level after the operational duration time of the first driving frequency level. The method includes based on determining the change from the first driving frequency level to the second driving frequency level, controlling to operate at the first driving frequency level or the second driving frequency level.
