auto-cpufreq: Automatic CPU Speed & Power Optimizer for Linux

Linux is great for so many reasons. Battery life is not one of them. Most users, with every new isntall, one of the first thing they install is TLP and/or Powertop. Tools like these definitely help with extending the battery life but they also come with their own set of problems. Like losing turbo boost.

Here’s where cpu-freq comes in. A simple tool which will automatically make “cpufreq” related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting.

  • Monitoring
    • Basic system information
    • CPU frequency
    • CPU temperatures
    • Battery state
    • System load
  • CPU frequency scaling, governor and turbo boost management based on
    • battery state
    • CPU usage
    • System load
  • Automatic CPU & power optimization (temporary and persistent)

NOTE: currently auto-cpufreq works with Intel CPUs only. AMD support is being worked on. The recently released update, v1.2, brings AMD support.

NOTE: There are no conflicts with TLP. auto-cpufreq works alongside TLP. However, from experience, there are no real benfits in running both TLP and auto-cpu freq. Unless you have a Thinkpad laptop and you want to set the stop charging threshold via TLP-UI.



  • via snap store, or command line with sudo snap install auto-cpufreq ( NOTE: snap version version must be >= 2.44 for auto-cpufreq to fully work )
  • auto-cpufreq is available in the AUR
  • Install from source code :
    git clone
    cd auto-cpufreq && sudo ./auto-cpufreq-installer



1. Monitor – No changes are made to the system, and is solely made for demonstration purposes what auto-cpufreq could do differently for your system. sudo auto-cpufreq --monitor

2. Live – Necessary changes are temporarily made to the system which are lost with system reboot. This mode is made to evaluate what the system would behave with auto-cpufreq permanently running on the system. sudo auto-cpufreq --live

3. Install auto-cpufreq daemon – Necessary changes are made to the system for auto-cpufreq CPU optimizaton to persist across reboots. Daemon is deployed and then started as a systemd service. Changes are made automatically and live log is made for monitoring purposes.sudo auto-cpufreq --install.

After daemon is installed, auto-cpufreq is available as a binary and is running in the background. Its logs can be viewed by running: auto-cpufreq --log.

Since daemon is running as a systemd service, its status can be seen by running: systemctl status auto-cpufreq

4. Log –  If daemon has been instaled, live log of CPU/system load monitoring and optimizaiton can be seen by running: auto-cpufreq --log

5. Remove – auto-cpufreq daemon and its systemd service, along with all its persistent changes can be removed by running:sudo auto-cpufreq --remove
