QCPUFreq : save battery power by adjusting your maximum CPU speed

Posted on 9:52 PM by SlipKoRnSaad

QCPUFreq is a GUI for the kernel's cpufreq interface. It allows you to adjust your CPU's maximum speed.
This prevents the CPU from working at full speed when you don't need it (e.g while browsing the web) which enables you to save more battery power.



It should work with vanilla and custom kernels so both normal users and overclockers could benefit from the application.

Note: changes are non-permanent. After a reboot your device is going to use the default maximum frequency set in /etc/pmconfig.

Requirements:
- N900 with PR 1.2
- no dependencies

Future plans:
- polishing UI
- upload to extras-devel/testing
- option for enabling SmartReflex
- changing scaling governor (only for power-kernel)
- use QDBus instead of sudo to set frequency
- l10n

Download the deb file if you want to test it : https://garage.maemo.org/frs/?group_id=1699&release_id=3801
