A simple app to display the time the CPU spends in each frequency state
Just like what the description says, CPU Spy helps you to identify which frequency state is being best for your phone. It certainly helps in overclocking your phone to improve its performance and battery life.
As you can see from the image above, CPU Spy also displays the kernel information on your current ROM. This helps those who likes to switch to different kernels to make sure they have the correct kernel installed.
Shown above is the default frequency settings for the kernel I’m using. As you can see there’s a 350 MHz state and it’s barely being used and 1350 MHz state that is not being used at all.
In order to improve its performance based on my usage, I choose to use 350 MHz as the lowest frequency while 1350 MHz for highest frequency.
Once set I waited for few hours to see how the configuration affecting my phone.
As expected it is best for me to set 350 MHz as the lowest frequency as it’s being used at times. While I should remove 1350 MHz as the maximum frequency as it’s barely being used.
By doing this I’m able to improve the phone performance as well as saving the battery life.
