What is it?
Its a fairly simple App that will put CPU1/2/3 OFFLINE when the screen turns off. Once the screen comes back on, it will allow CPU1/2/3 back ONLINE.
How does it work?
Since we have Quad Core CPUs, we have a CPU 0 and a CPU1/2/3, while the screen is off we really only need to have 1 core active "CPU0", this App will make sure CPU1/2/3 shuts off while the screen is off, then resumes normal usage when the screen comes back on.
Battery savings all depends on Usage & idle times.
Most People will notice a Huge battery savings using Music App's like Pandora and using the Phone during calls.... etc.....
