auto-cpufreq is an automatic CPU and power optimizer for Linux which actively monitors laptop battery state, CPU usage, CPU temperature, and system load. It’s designed to improve battery life without making compromises.
auto-cpufreq aims to replace TLP in terms of functionality, so after you install auto-cpufreq it’s recommended to remove TLP. Using both for the same functionality (i.e., to set CPU frequencies) will lead to unwanted results.
This is free and open source software.
Key Features
- Monitoring:
- Basic system information.
- CPU frequency (system total & per core).
- CPU usage (system total & per core).
- CPU temperature (total average & per core).
- Battery state.
- System load.
- CPU frequency scaling, governor, and turbo boost management based on:
- Battery state.
- CPU usage (total & per core).
- CPU temperature in combination with CPU utilization/load (to prevent overheating).
- System load.
- Automatic CPU & power optimization (temporary and persistent).
- Settings battery charging thresholds (limited support).
- Conservation mode and support for Lenovo-compatible laptops.
- Support for configuring/overriding “Energy Performance Preference (EPP).
- Battery charge thresholds limit.
- Ability to force use of powersave or performance governors.
