Summary:
Power saving is one of the essential themes in smartphones. There is a trade-off between CPU processing performance and CPU power consumption. It is desirable to control the CPU clock rate to increase when necessary and decrease when unnecessary. In smartphones, the foreground applications' CPU resource consumption dominantly determines the entire system's CPU resource consumption. In addition, the CPU utilization of an application strongly depends on the running method. In our previous work, we proposed a concept for controlling CPU clock rate based on the invoked method in the foreground application and a method for investigating the CPU utilization of each method invocation. In this paper verifies our CPU utilization investing method and discusses its accuracy and stability.
