CPU Factorial Test

This app tests the CPU energy consumption by computing large factorials.

How does it work?

This app engages a loop which calculates the factorial of 78585656 on an interval determined by the frequency provided.

Frequencies

For this app we used the following frequencies:

• Low frequency: 3 seconds
• Medium frequency: 2 seconds
• High frequency: 1 second

Changing the frequency

You can easily change the frequency by opening the project in Android Studio, go to the MainActivity.kt class look for the sentence handler.postDelayed(runnable, low_frequency). Here you can change the frequency by simply substituting low_frequency with medium_frequency or high_frequency.

Benchmark settings

Use phone settings:

• Disable WiFi
