In Picture 2 we can see there are 8 CPUs, each CPU with a fairly high load.

  1. CPU 1: 45.5%
  2. CPU 2: 45.0%
  3. CPU 3: 45.0%
  4. CPU 4: 60.0%
  5. CPU 5: 50.5%
  6. CPU 6: 50.0%
  7. CPU 7: 65.0%
  8. CPU 8: 47.1%

My CPU has an average usage of 51.01%, wow it is very high even though there are no programs that I open. This really annoys me. Then I looked for information on how to reduce high CPU usage on Linux.

How to Reduce High CPU Usage with no Activity?

After browsing for several hours, I finally found a way to reduce high CPU usage on Linux. Although this method is not permanent, it means that if you reboot your computer, CPU usage will return to high. This means that this method is only used once.

Step by step to reduce CPU usage on Linux Mint:

  1. Press together Window Logo + L (the letter L on your keyboard).
  2. The Melange window will appear.
  3. In the lower right corner click Action.
  4. Then click Restart Cinnamon.
  5. After 5 minutes check back the CPU Usage.

This is my CPU after Restart Cinnamon:
