*Note: Doesn't seem to work on most recent roms. Tested on ICS only. Sorry but there is nothing I can do.*
This app does not work on Phones other than LG Optimus P880 4x HD on stock rom!
Please do not download if you are using another phone or cyanogenmod.
However it does not require root.
This App launches the hidden QuadGearBox (Eco Mode) in LGs Tegra 3 Device(s).
It is tested and works on the Optimus P880 4x HD, however there may be a reason LG has not yet published this option. (Not fully tested/functional).
This is likely to increase your battery performance as it will use lower clock rates.
Be sure to stop eco mode before playing games, though. ;)
