Automatic CPU speed & power optimizer for Linux based on active monitoring of laptop's battery state, CPU usage, CPU temperature and system load. Ultimately allowing you to improve battery life without making any compromises.
For tl;dr folks there's a: Youtube: auto-cpufreq - tool demo
One of the problems with Linux today on laptops is that CPU will run in unoptimized manner which will negatively reflect on battery life. For example, CPU will run using "performance" governor with turbo boost enabled regardless if it's plugged in to power or not.
Using tools like TLP will help in this situation with extending battery life (which is something I did for numerous years now), but it also might come with its own set of problems, like losing turbo boost.
With that said, I needed a simple tool which would automatically make "cpufreq" related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting. That's how auto-cpufreq was born.
Please note: this tool doesn't conflict and works great in tandem with TLP.
Supported devices must have an Intel, AMD or ARM CPU's. This tool was developed to improve performance and battery life on laptops, but running it on desktop/servers (to lower power consumption) should also be possible.
auto-cpufreq is available on snap store, or can be installed using CLI:
sudo snap install auto-cpufreq
Fedora users will encounter following error. Due to
cgroups v2 being in development. This problem can be resolved by either running
sudo snap run auto-cpufreq after snap installation. Or using auto-cpufreq-installer which doesn't have this issue.
Get source code, run installer and follow on screen instructions:
git clone https://github.com/AdnanHodzic/auto-cpufreq.git cd auto-cpufreq && sudo ./auto-cpufreq-installer
In case you encounter any problems with
auto-cpufreq-installer, please submit a bug report.
systemctl start auto-cpufreq to start the service. Run
systemctl status auto-cpufreq to see the status of service, and
systemctl enable auto-cpufreq for service to persist running accross reboots.
auto-cpufreq can be run by simply running the
auto-cpufreq and following on screen instructions, i.e:
sudo auto-cpufreq --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 --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.
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 stats are generated 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 stats can be viewed by running:
Since daemon is running as a systemd service, its status can be seen by running:
systemctl status auto-cpufreq
If install has been performed as part of snap package, daemon status can be verified by running:
systemctl status snap.auto-cpufreq.service.service
auto-cpufreq daemon and its systemd service, along with all its persistent changes can be removed by running:
sudo auto-cpufreq --remove
If daemon has been installed, live stats of CPU/system load monitoring and optimization can be seen by running:
