Lemme note here, I deserve no credit, all code and all work was done by Eugene_373 and anyone mentioned below, this is simply a share from the T-MOBILE GALAXY s2 section of XDA, I have fully tested this app and found it to be working wonderfully on my SGH-I777
I love eugene's deving hence the share I hope you all enjoy if this has some way helped you in anyway go over to eugene's profile donate/thank him
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 1.5 Release Notes:
~ Battery Drain issues 100% Fixed
~ Screen on Lag 100% Fixed
~ SU issues 100% fixed
~ Auto-Start on reboot 100% Fixed
~ Fixed Auto-Start killing Cell Service
~ Su Request on Screen Wake Fixed
~ Debugging enabled for those wanting to check if it's working.

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]
[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.

Hotplugging and sched_mc are kind of synonymous. The difference is that sched_mc allows you to force a particular pattern of behavior (1 = fill 1 core first, 2 = activate both). This app attempts to force 1 core offline when the screen is off. It's kind of like an extreme version of sched_mc = 1 in that it doesn't allow both cores to be activated. However, I'm not sure if it is capable of preventing the second core from coming online. It may check periodically and subsequently turn it off. I don't think it would have much benefit on our devices; our hotplugging is competent and sufficient. I suppose anything is worth trying though.
looks interesting!
Every now and then i get cpusleep has been granted superuser permissions when the screen is on and im surfing the net or playing a game.

Does it work fine with setcpu ?
This is an unofficial build of AOKP (Android Open Kang Project) for the new Jelly Bean bootloader for the Transformer Prime.
This uses a modified version of my Jellybean CM device & vendor tree... including the new 3.1 Jelly Bean kernel and the new Jelly Bean drivers and proprietary files. THIS REQUIRES THE NEW JELLY BEAN BOOTLOADER.
For the most case, this ROM uses the official commits to the AOKP github. The exceptions are the TF201 device specifics. This ROM uses the new 3.1 Jelly Bean kernel and the new Jelly Bean drivers and proprietary files.
Highlights of this ROM:
1) Android Jelly Bean 4.1.2 JZO54K
2) Built using the latest AOKP changes as of 31 Oct 2012 6:30PM Pacific Time (GitHub / Gerrit)
3) Uses the a modified and tweaked version of my CM10 TF201 device tree with the Jelly Bean 10.4.2.15 kernel (3.1) and proprietary files & drivers with some changes (GitHub)
4) Needs the new Jelly Bean 10.4.2.15 bootloader [IMPORTANT: Flashing over an incorrect bootloader can permanently brick you device.]
5) HDMI audio/video streaming and bluetooth audio streaming (AVRCP 1.3 ready)
6) Camera and microphone
7) 4-way reboot menu (Reboot, Recovery, Fastboot & APX Mode)
8) Includes all the files and changes need for the Google Widevine DRM [untested!!]
9) CIFS and NTFS (read-only) support
10) Dock battery display
12) All other features of AOKP and Jelly Bean (full hardware acceleration, Project Butter, HD video, customisable notification toggles & many more)
13) Some custom addons and feature ports by me...
New in Oct 31 2012 build:
1) BFQ v5, SIO & V(R) I/O schedulers. SIO set as default
2) Lulzactive & Pegasusq CPU frequency governors.
3) Standardise CPU frequency tables' values & disable Asus system mode CPU speed restrictions
4) Enabled zRam/Compcache & KSM (Kernel SamePage Merging) support
5) Fixed model number & LCD density
6) Several device overlay updates and cleanups (bunch of updates for JB)
7) Auto-brightness turned off by default
8) Cleaned-up & updated release tools script (this creates the zip packages)
9) Set correct permission for BtService.sh (Bluetooth DUN) script
10) Force NV_FPS_LIMIT to 60 for all performance modes
11) Device Advanced settings menu to set Asus performance modes (defaulted to Balanced). This is not for the CPU speed, rather the Tegra performance setting (cpuX.sh like functionality) [Read know issues below]
13) Updated device power profile based on official JB release
Known issues:
1) Some locale specific layout for the dock keyboard may not work
2) Auto-brightness is funky [Use the app Lux for auto-brightness]
3) NTFS support is read-only
4) exFAT is not yet supported
5) Torch does not work
6) The "Device Advanced settings" does not show up in the Setting menu. If you want to use it, use an after-market launcher (Apex, ADW, Nova, etc.), and create a Shortcut to the Asus Transformer Prime settings...
Important:
1) Wipe data/factory reset if coming from any other ROM
2) After flashing a build, it is a good idea to wait for 5-10 mins after bootup to allows everything to settle in
3) If you have not upgraded to the official Jelly Bean ROM yet, you will need to flash my CM10 Oct 13 2012 build or a stock JB ROM first to upgrade your bootloader, and then you may flash the latest build here.
4) Make sure you use a recovery compatible with the new Jelly Bean bootloader after flashing this ROM.
The usual 9 yards:
1) Have you read this post properly. Read it again!!
2) You need to have an unlocked bootloader
3) You need to have a custom recovery (CWM or TWRP)
4) It is a good idea to have enabled nvFlash (thanks to AndroidRoot) so that you can recover from almost any brick
5) Neither I, nor the AOKP team, nor the AndroidRoot team take any responsibility if anything goes wrong. Use at your own risk
6) Always make sure you create nandroid backups regularly

ok will try to re-install, since nobody else has similar issue.
AOKP Wallpapers doesn't work not a big deal, some navigation bar settings dont stick like setting the spacing between the soft buttons, also the recent apps button has the glow cut off. All minor bugs that don't affect performance at all. I feel performance is below that of cm10 but for an early test build it is fantastic
Not sure if its just mine but the Navigation soft keys are not space correctly. Too wide. With 4 soft keys it takes up half of the left side. Just reporting. Can't wait for more. Thanks Craig.

Yes you can change the space in settings.
Will go back to cm10, don't think I like AOKP, it's basically same cm10 just loaded with a lot of stuff that I don't need, and looks like it's slowing the performance, animations from changing apps or from pop-up's are very slow and laggy.
craigacgomez, any way you could fix MTP connection (I have to use it a lot) ?)) On this rom it does't work too.. or maybe that's just me. But other than that your cm10 rom is great)

AOKP focuses more on extra customisation... CM10 more on features & stability... there is a lot of cross merging between th e two...
I haven't had any issues with MTP, so could you provide a logcat?
So far so good, installation with only one hiccup, a hot reboot while opening for the first time Play and a freeze while navigating in Performance Menu.

ok I removed the mounting from vold, still doesn't work. still shows "getVolumeState(/storage/sdcard1): Unknown volume" I think its going to show it even if there is no sd card inserted, and normally bad sd card will not cause MTP to not work.

[kernel][v3.5] leanKernel: minimalistic kernel (1/28/16)
leanKernel is not for everyone.
My philosophy is to keep the kernel footprint as small as possible by trimming as much fat as possible, and at the same time keeping it stable, power efficient, and fast. leanKernel is designed to be a drop in replacement for stock kernel, and so it tries not to deviate too far from stock.
You will find that it's lacking some of the bells and whistles of other custom kernels, so if you like features you came to the wrong thread.
Here's a longer post on what leanKernel is about.
Also folks, please read the FAQ before asking questions.
INSTRUCTIONS
If you like to stay as close to stock as possible: 1) Download and flash the normal leanKernel build here (find the latest zip file) in recovery. 2) Reboot and enjoy better performance and battery life (hopefully). That's it! There's no need to flash stock kernel first, or to wipe caches.
If you like to customize, read through the feature list below, the FAQ (post #2), the changelogs, and optionally the entire thread. Then you'll know what to do.

FAQ
I'm having trouble waking the phone sometimes. Help!
We haven't really figured out exactly what's causing it - but there seems to be evidence that it's not limited just to leanKernel. One thing to try: if your ROM has a feature that prevents accidental wakeups, disable it!
I can't seem to get min and max freq to stick! What are these mpdecision zip files in the util directory?
* Read this post: http://forum.xda-developers.com/showpost.php?p=58135730&postcount=1474
* Short version: This is actually by design of mpdecision. If you want this behavior to change, I recommend that you 1) flash latest stable leankernel, 2) flash the custom no-freq mpdecision, and then 3) disable cpu-boost via lkconfig. Do not disable mpdecision if you go this route. Also, if you flash ROM, you must re-flash custom mpdecision. To go back to normal, flash the stock mpdecision file.. Launch lkconfig, choose core control, and choose one of the options in core control.
Will flashing leankernel decrypt my phone storage?
If you're already encrypted, then it will stay encrypted after flashing kernel, *until* you format data. Once you format you will stay decrypted until you decide to encrypt again (see below). If you're already decrypted, leanKernel will not force encrypt automatically.
What do I do to encrypt again?
There are several ways to do this. One way (easiest for me at least) is to adb in (or in terminal emulator):
Code:
[email protected]:/ # start encrypt
You will see the phone hot boot and once it comes up you will be encrypted again. Keep in mind that if you want to decrypt again you'll have to wipe.
How do I check the PVS BIN of my cpu?
Code:
[email protected]:/ # cat /proc/cpu/msm_acpu_pvs
The number you get should range between 0 and 15 (inclusive). If you ended up with 15 congratulations. If you ended up with 0, go get it exchanged! Stock frequency/voltage table: http://pastebin.com/ZyGA9Tec
Which kernel control app do you recommend?
When v1.0 gets released it should come with "lkconfig" for tweaking some of the options. Otherwise, I tried Trickster and KernelTweaker, and they both seem to work ok.
What are ondemandX and interactiveX?
ondemandX and interactiveX are very very close to "stock" ondemand and interactive governors, respectively. The only difference is screen_off_maxfreq sysfs support. This means that it gives you the ability to limit phone's max frequency when screen is off. This feature could be effective in reducing battery usage, especially if you have a misbehaving app (or two) that consume cpu cycles while screen is off. The default value is 2265600 - if you change the value to your top speed you're effectively disabling the feature and restoring stock behavior completely. You can use an app like Trickster or Kernel Tweaker to modify screen_off_maxfreq.
HELP! I messed up with lkconfig - how do I go back?
Do not fret. Flash lkconfig_cleaner.zip from the "util" directory.
(If you want to do this manually), reboot the phone into recovery, mount /data, and delete everything in /data/data/leankernel. Once things are back to normal, re-run lkconfig to re-do your settings.

It should not decrypt if you're already encrypted, unless you re-format/wipe. But no guarantees.

You mean lkconfig? Yeah that's coming later (along with a whole lot more).. If you're talking about f2fs, you'd want to use custom recovery but TWRP for shamu doesn't support f2fs yet - i had to do everything manually.

It should not decrypt if you're already encrypted, unless you re-format/wipe. But no guarantees.

i am still encrypted, and did not decrypt after flashing. so, all worked as it should.
Can we flash on stock ROM or is a custom ROM required?
So let me see if I get this straight: I'm on stock, unlocked bootloader, rooted, and encrypted (as far as I know--I never decrypted), so if I flash this it won't decrypt my device? I was kinda hoping it would.
Secondly, I'm good to flash this with stock ROM? I'm hoping for a bit better battery life.
Thanks devs! I got a feeling development for our device is gonna be NUTS!!

wipe before flashing, youll be decrypted. if you dont wipe, you stay encrpted.

AFAIK, there's no way to decrypt without having to wipe unfortunately. Going the other way (unencrypted to encrypted) is super easy though, and no data loss.

Hello all, please has someone already succeeded in running Remix with newer kernel ? I'm asking as I have some issues that I hope could be solved by using newer kernel...
I already tried booting it with 4.9 kernel taken from some beta Android 7.1 for x86. (I had to unsquash the system.sfs and squash it again using gzip, as that kernel has no support for LZ4 compression). The kernel itself boots ok, I can even boot to shell using DEBUG=2. But when trying normal boot, it ends with some emergency remount r/o and reboots so quickly I can't read the messages. It also says it saves logs to some location, but there are no saved.
The issues I see, that I hope could be better using newer kernel then with the original 4.4 from Remix 3.0.207 are:
- Some CPU idle states problem, probably related to quite new Intel CPU J4205, causing system very very slow and unusable. As workaround I'm booting with "idle=halt" option, but that probably has bad influence on cpu power. The 4.9 kernel seems to work ok even without this option.
- After wakeup from standby, the 1st CPU core runs on max. frequency all the time, and at the same time problems like bad video playback performance start. No process seems to be causing that, there is still some 380% out of 400% cpu idle, similar like before standby.
Kirisakura-Kernel for the Sony Xperia 1 IV
Hello everyone,
To keep it short: Here is Kirisakura- GKI - Kernel for the Sony Xperia 1 IV aka Nagara. Nagara is the internal codename for this years development platform of Sony Mark IV devices.
I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.
Kirisakura - Kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
If you expect a custom kernel to magically improve your devices battery life manifold and this is your only priority then this might not be the right place for you.
There´s also a cpu-battery saver mode that cuts back the CPU max- freqs, but without the disadvantages like delayed notifications from built into the system user-space power-saving modes.
If that got your curious, I welcome you to continue reading if you´re still interested!
Now lets continue with a list of features in the next paragraph!
Main Features:
- Based on kernel/common 5.10.149
- compiled with Clang 12.0.5
- CPU-Battery saver to be able to restrict max cpufreqs on the fly, without enabling powersaving modes that might cause missed notifications (see second post)
- SSG IO scheduler for reduced overhead and less CPU cycles (more lightweight and android optimized)
- Power saving workingqueues enabled by default
- Change various drivers to use power efficient workingqueues. This compliments EAS in general
- implement LRNG (thanks @arter97, see arter kernel OP for more info )
- Enable support for TTL spoofing
- wakelock blocker with the ability to block any wakelocks (dangerous, use with caution)
- please read [URL="https://arstechnica.com/gadgets/2018/08/p-is-for-power-how-google-tests-tracks-and-improves-android-battery-life/"]this for further info
- f2fs improvments for better efficiency
- scheduler improvements
- psi fixes
- Flashing the kernel will keep root!
- Flashable via EXKM, FKM or TWRP (if available) on a rooted system!
Flashing Guide, Download and Changelog
Requirements:
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- magisk root
- a backup of stock boot.img or your magisk patched boot.img in case you want to go back to stock.
How to flash the Kernel:
1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Firmware (check the feature list for the current firmware the source is based on). When there´s an OTA update for the Sony Xperia 1 IV it takes Sony a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
If you want to be sure there are no issues, always make sure to run the firmware the kernel is built for!
If you feel adventurous and try in advance, make sure you have a backup ready!
2. Flash the kernel.zip via latest TWRP (if available), EXKM or FKM app and do a full reboot.
3. Reboot and profit.

F.A.Q:
Question: Is root preserved when flashing this kernel?
Answer: Yes, the AnyKernel.zip will detect root and keep it.
Question: Safetynet does not pass on my phone since I unlocked the phone, why is this so?
Answer: Google introduced hardware backed attestation recently. Unfortunately the old kernel tricks to still get safetynet passing won´t work. Instead you will have to rely on some magisk modules. Short guide in post #4 below.
Question: How do I return back to stock or another kernel.
Answer: Extract boot.img from the matching firmware you are on (you can do so by using this tool or similar ones found on XDA and when googling around) and flash via fastboot. If you want to keep root flash back the magisk_patched_boot.img. Or dirty flash your rom and re-root.
Question: Why is having Magisk installed mandatory for this kernel?
Answer: The kernel uses a ramdisk overlay to apply some settings after boot. If you are not rooted these settings will not get applied and you miss some of the optimizations.
Question: How to report bugs properly?
Answer: Have a look at post #3 in the linked thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re running on a stock configuration. That´s means you´re not using any mods, tweaks in kernel managers or other root tweaks , magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic, sleeping behaviour, scheduler, magical battery tweaks etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.
Feature Documentation:
Here´s a brief documentation about some of the features included in the kernel that can be changed as the user desires.
They can be accessed via either terminal, scripts or for example EXKM manager ( tools -> user settings).
CPU-Frequency Limiting:
Another option is CPU-Freq Limiting. You can now limit the CPU frequency to a few different levels with a sysfs interface. Original implementation is from @tbalden, I only changed it to be accessible via traditional root methods.
Main Switch:
sys/module/cpufreq/parameters/batterysaver
Set this option to "1" to enable the feature
Max-Frequency Selection (Input boosts, such as scrolling boost or app launching boosts will still apply, if touch boost restriction is not set to 1)
sys/module/cpufreq/parameters/batterysaver_level
Set this to "1" to restrict the max CPU-Freqs to 1,6GHZ/1,9GHZ/2,22GHZ (Little Cluster/Big Cluster/Prime Core)
Set this to "2" to restrict the max CPU-Freqs to 1,4GHZ/1,6GHZ/1,8GHZ (Little Cluster/Big Cluster/Prime Core)
Set this to "3" to restrict the max CPU-Freqs to 1,1GHZ/1,1GHZ/1,1GHZ (Little Cluster/Big Cluster/Prime Core)
Touch-Boost Restriction
sys/module/cpufreq/parameters/batterysaver_touch limiting
Set this to "1" to restrict the powerhal from boosting over the limit defined in batterysaver_level
Set this to "0" to allow the powerhal to boost above the values defined in batterysaver_level, but only during interaction with the Phone!

This is for example very useful during gaming to prevent additional heat, if not the highest performance from the CPU is required. Check if the game is running fine on level 1 or 2, and you´ll notice much less heat. Powerdraw will be reduced as well.
Another very useful trick while doing video calls or long extended navigation sessions with google maps to preserve battery or keep the phone from heating. Especially during summer if the ambient temperatures are high.
This is a very easy way to preserve battery or reduce heat without toggling the battery save mode in settings as that restricts background data usage, which can lead to delayed notifications.
How to pass Safetynet after unlocking the bootloader
With the introduction of hardware backed safetynet attestation, passing safetynet has become a lot more complicated.
Some probably remember a while ago, flashing a kernel that forced some flags was enough to pass it. However these days are gone.
Below is a short guide how to pass safetynet on phones that are flagged to use HW attestation (such as the ROG 5).
1. Make sure you´re running latest magisk canary.
2. In Magisk Manager enable both zygisk and deny list.
4. Download the latest Universal Safety Net Fix from @kdrag0n ´s github for zygisk cand flash it in Magisk Manager. Reboot.
5. Profit
Oh, my God! thank you so much for making the IV kernel
am I right to assume that CPU frequency limiting can help the phone not overheat when taking photos?
You are Awesome

yes. it should at least slow down the heat buildup. that´s the main goal behind it.
please note that 4k 120fps recording or other demanding tasks might not work without stutters if CPU gets restricted too much.
Apart from app loading times, if the usage is not super demanding level 3 works without major stutters in the UI on 120fps refresh rate.

excellent <3, I don't need 4K 120fps recording I actually only do 1080p 24 because I like stabilization. so going to flash 64.0.A.8.25 and this kernel after that. million thanks!
It's a small amount, but I donated it, thank you always

Hahaha... Hello my good friend @Freak07. Didn't know you were into Sony as well.
@Freak07 can you port it to xperia pro i ?
Developer, I have a question
If I use my work profile (shelter or island apk) I can't get into the settings menu I get a popup stating that the system UI is shutting down, maybe it's kernel related?
Should I uninstall Uperf before flashing?
Also thanks for this excellent work.
great work!Thx
to those who flashed, how is battery live ?
ist compüatible with latest sony update?
Would be interested to know, if it supports the old android kernels feature to emulate CD and DVD. Its a feature that DriveDroid needs to emulate a bootable DVD drive from an *.ISO hosted from an android device over USB. it was present in my older devices until XZ1 Compact and i was able to boot my pc off from a iso file hosted on my android device. It was much convinient than using silly PXE boot over eth0
No more update ?
