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.

v2.7
App Download: CPUSleep.apk

v2.8 via Market
CPUSleep.apk
Version 2.8 Release Notes:
~ Fixed GPS Not Locking while App is installed
~ GNex Freeze Issue should be Fixed
~ JB Compatibility should be fixed regarding Sleep Of Death
~ Fix Quad Core Sleep Issue's
~ Better Handling of CPU2 & CPU3 on Quad Core's

Credits:
Handlerexploit for co-creation of this wonderful App.



Script Version!
Code:
This time I present to you a script that will in theory (and so far for me, in reality) save us some battery without having to risk our hardware with undervolting! I present to you...

[B]CPU Sleeper[/B]
[QUOTE]Honestly the Script can be made to work with any Dual Core / Quad Core! The Only Problem is you need to be Rooted!  
~ Currently the issue with CM9, is that the boot becomes incomplete while in init.d folder without Modification to the sysinit..  
 
~ however, with any rooted device you can download the script & continue to use it via a script manager app on every boot.  
 
~ With the Script Manager App, this script virtually can run on any Multi-Processor CPU  
 
Hope that clears things Up,

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

[U]How does it work?[/U]
Since we have dual core CPUs, we have a CPU 0 and a CPU 1, core 1 and core 2, while the screen is off we really only need to have 1 core active, this script will make sure CPU 1 shuts off while the screen is off, then resumes normal usage when the screen comes back on.

[B][COLOR="red"]WARNING! READ THIS![/COLOR][/B]
This script relies on init.d OR script manager! CM9, for some reason, tends to run this at the exact same time it runs some other script (I forget atm which) and it will clash, causing no boot! CM9 users MUST use the script manager version install! Flex Reaper appears to work fine with it as init.d. I strongly urge you to use the script manager version of this, NOT the flashable version. Always make a nandroid backup before modifying the system, including this!

[U][COLOR="Red"]Instructions[/COLOR][/U]
Available in 2 versions, script only version which you can place wherever you want and run however you want, or a CWM/TWRP flashable zip that will place the file for you in /system/etc/init.d and set permissions.

[I]Version 1: Flashable[/I]
Same as any of my flashable releases, I did most of the work for you!
Make a full backup
Download to external SD card
Install from SD card
Pick the cpu sleeper zip file
it'll be almost instant
reboot
Shouldn't be any need to clear caches or anything like that.

[I]Version 2: Script only[/I]
This can be run in 2 ways, via init.d support, or via script manager. Both are pretty similar, and can be done a number of ways, however this is the basis of how.

[U]Init.d supported kernel:[/U]
Make a backup!
Download the script file, making sure no extensions get added onto the file. Copy the file to /system/etc/init.d and set the permissions to the following:
XOX
XOX
XOX
Once done, reboot the system, and it will take effect when your system is finished rebooting.

[U]Script Manager[/U]
This method is probably the better method, and should work with any kernel/ROM. Download the script file, making sure no file extensions get added, and copy it to /system/etc. Set the file permissions to:
XOX
XOX
XOX
Once done, load up script manager, select browse as root (if it isn't already set from the crossix mod method in the guide) then browse to /system/etc and select the script file S98cpu_sleep, then select ROOT and BOOT options. After this is set, reboot system.


[U]What do I do if I can't boot after using this?[/U]
You made that backup, right? Ok, then here is what you do.
Hold the power button until the tablet powers off
Press and hold the volume down button, next to the screen lock switch
Press and hold Power (while holding volume down)
Once the recover kernel message comes up, release the buttons
In CWM go to advanced, mounts, mount system, then format system
In TWRP, go to wipe, then wipe system
In CWM go to restore, advanced restore, restore ONLY system
In TWRP select restore, then uncheck all so ONLY system is checked
After restoring system, wipe cache and dalvik cache, then reboot system.
System should boot normally.

Will the phone function well with the asleep profile you created on the scary governor?

You can just leave the naming the same, user preference.

Yes it will function correctly regardless of Gov selected, all we're doing is ensuring that cpu1 goes to sleep.
