==New update:== Added the usage of process SIGSTOP, this should prevent greedy processes such as trackerd, browserd, calender-ui... from eating power while your device is idle.

These processes will "pause" while your device is idle, which should result in a drastic battery improvement.

Put both CPUTweak.tar and CPUTweak.sh.txt in ./MyDocs then open Xterminal:
Code:
root
apt-get install dbus-scripts
cd /home/user/MyDocs/
sh CPUTweak.sh.txt
Default settings here are:
Idle: 0 500MHz starving vfs_cache_pressure 10
paused processes: browserd scim-panel-gtk image-viewer

Active: 500 1150 MHz ideal vfs_cache pressure 100
