App Version:
CPU Sleeper
~Free to all XDA Memebers
~ Must Be Rooted to use App

What is it?
Its a fairly simple App that will put CPU 1/2/3 OFFLINE when the screen turns off. Once the screen comes back on, it will allow CPU 1/2/3 back ONLINE.

How does it work?
Since we have Dual & Quad core CPUs, we have a CPU 0 and a CPU 1/2/3, core 0/1/2/3, while the screen is off we really only need to have 1 core active "CPU0", this App will make sure CPU 1/2/3 shuts off while the screen is off, then resumes normal usage when the screen comes back on.

Compatibility?
Works with any Dual Core & Quad Core Devices!
~ICS
~Gingerbread

Battery Saving?
Battery savings all depends on Usage & idle times.

App Download: CPUSleep.apk
Version 1.3 Release Notes:
~ Fixed issue with Phone getting hot
~ Secondary Cores will now Disable while Talking on Phone if Needed
~ Secondary Cores Now Come back online
~ Fixed Superuser Notification being displayed every second
~ Fixed Cores Coming back online while screen is Off
~ Phone's while charge semi-faster while not being used
~ Fixed Lag issue when coming back online

~ Auto-Start on Reboot is still borked

Does CPU Sleeper require root access?

When I try to start the service, Superuser denies access.

How can I get Superuser to allow the CPU Sleeper service to run?

Go into the super user app, and remove the allow/disallow option for it, then try it again.

The app requires SU, the script does too, but is run in the background, so SU never asks about it or cares that it runs.

Thanks, @pio_masaki, but how do I allow an app in Superuser? I run Superuser, but I don't see any way to allow/disallow apps.

Update: I apparently had lost my root access and had to re-root. Working fine now. Thanks again for your help.
