New Directions:
As there will be more tweaks and findings out by xda members, i will not include much tweaks (unless those i run) into my kernel but to release source so others can incorporate my oc/uv into their "all-in-one" kernel threads.
im glad someone took the liberty to add voodoo kernel and hope he eventually get voodoo to merge nicely with modded cwm.
UV control version 2.1 and above
- voltage scaling
- full UV user control via sysfs
- works on all governor
- echo "50 50 150 75 75 100" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

OC / UV 101
This question has been asked a lot so I will try my best to answer this question to my knowledge. Our phone although uses the same hardware, they can vary in terms of stability and performance. I believed even same hardware varies because of production tolerances & variations. Our stock 1ghz system per datasheet should run at 1.2v, however, in the source code, samsung set it at 1.275v. There are a lot of speculation why this happens but my personal believe is due to production fallouts. In production environment, to increase the yield, they increased the voltage to make them more stable. This is the easiest way to increase yield and sound most logical in business standpoint.
Our phones do frequency scaling. Meaning it doesnt stay at a particular frequency all the time, the frequencies fluctuate depending on load and thresholds. At high load, it will go to high frequencies and when low load or idle mode, it will stay around 100-400 range. In this way, you get load balance and uses lesser power.
Back to how adjusting UV to suit your phone. I've enabled via sysfs (/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table) the ability for user configurable UV, unlocking this allows for UV'ing at all supported frequencies 100/200/400/800/1000/1200mhz. In this table is an array of values in mV, column 1 for 1.2ghz, 2 for 1ghz, 3 for 800mhz, 4 for 400mhz, 5 for 200mhz, lastly 100mhz. What this means is each column allows an UV setting at you can change to suit your phone. In boot up stage, all the values in the array is zero hence no UV'ing. You can set it and here is how it works:
Taking for example, you echo "0 50 50 75 75 100" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table, looking at the stock voltage info I've described above, you will get:
1200000 -> 1300-0 = 1300mV
1000000 -> 1275-50 = 1225mV
800000 -> 1200-50 = 1150mV
400000 -> 1050-75 = 975mV
200000 -> 950-75 = 875mV
100000 -> 950-100 = 850mV
At 1.2ghz, i disabled UV by setting the value to 0. This is because 1.2ghz is already OC'ed so some phones may not be able to run stable so UV'ing makes the situation worst. At 1ghz, i reduced by 50mV, this is trial and error, i wouldnt know if this is stable unless i do some benchmark, run some programs, etc. So the question is "how do i know the UV i set is stable?" You can do this by a few ways. For my case, this is how I do it:
1) Set the voltage for 1ghz at 25mV
2) Use SetCPU to limit max and min scaling frequency to 1ghz
3) Run test, play some media, surf the web, open market place, etc.
4) Run it for 30-45 mins and if it doesnt crash, its good.
5) Increase the mV to 50mV and repeat 2-4 until it hang or crash
6) Find the mV that you phone likes without hanging or crashing then move to 800mhz
For lower frequencies, you can "usually" have higher UV but you cannot use setcpu to test the lower frequencies as the system will run above the max scaling frequencies even if you try to limit it lower (edit: this happens only if min and max frequency is not equal). For example, you limit the max scaling frequencies to 200mhz, it wont stay max at 200mhz but jump higher. The easiest way to test the lower frequencies UV is by letting your phone standby, sleep or do less intensive stuff and see if it runs stable, I believed most phones can do 75mV at 100-200mhz range but you can try more and see how it works out for you.
You can also test the lower frequencies by setting both min and max scaling to the same frequency. However, do note that setting low frequency will be very slow especially if you try it at 100mhz. It may take several seconds just to change apps.
FAQs
Q - What is UV? Why UV?
A - UV stands for Undervolt. The idea is to run at lower than stock voltage at any frequencies hence saving battery and longer battery performance
Q - Does UV also slow down the performance?
A - Theoretically it doesnt but under certain circumstances when the voltage gets too low for the cpu to operate properly, you may encounter some glitches so the idea is not to run it at the all the way down but find a suitable voltage that it doesnt happen. For example, running 75mV is stable but sometimes see some slow down so up it to 50mV and it should run fine.
Q - I am not convinced, I do not want to OC, how can I stop that?
A - Simple, using xan's app, check the box "limit max clock to 1ghz (no overclocking)" or using adb shell echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Changelog
v300
- ULF v0.4pre
-frequencies supported are 1400/1360/1280/1200/1120/1000/800/400/200/100 (in this order)
- echo 0 0 0 1 0 1 1 1 1 1 > /sys/devices/system/cpu/cpu0/cpufreq/states_enabled_table
- Frequencies state can be enabled by echoing a "1" into the column position (1.4ghz - 1st column, 1.36ghz - 2nd column, 1.28ghz - 3rd column,... etc)
- examples above will enable 1200/1000/800/400/200/100
- At default stage, all the OC frequencies will be disabled so user will have to enable if they want to OC.. it will only run ONCE when scaling start (so using init.d to set the states) but i've added a trigger called /sys/devices/system/cpu/cpu0/cpufreq/update_states which by default will be 0. echoing a 1 will force an update if you want to change the state.
- There will also be UV for each frequencies same as previous version

look forward to hardcore incorporating this into his kernals.
REALLY interested in this.
I'll install this when it's further in the development stage.
Will you be adding features/themes to this rom or will it be OCing only?

Yes, this makes V6 rom to kick a$$
YES YES hes back!
May I make a first request:
Consider basing this kernel on sztupy's work, making it fully compatible with ext4, jfs and his CWM.
AFAIU(as far as I understand? lol) JFS is not supported in this release?

not sure about jfs, but this works well on my set which was previously on sztupy's kernel (and the memory-tweaked kernel that's based on sztupy)

- If you'd like to donate to any of these ppl please do so because they're the ones who made this possible, i'm just making it simple and hopefully preventing questions from everywhere about battery/kernels/roms , which is the best etc etc. And remember the kernel is most responsable for your battery life. So the point is you can use any rom of your choice with this kernel as long as you do things right. And follow what i wrote down there.
As for me i'd be happy just with simple *thanks* button if this was helpful to you in any way.
------------------------------------------------------------------------------------------------------------------------------------------------
ROM, Kernel, Undervolting, underclocking, overclocking settings:
ROM Settings:
Roms should be cleaned with RomCleaner tool just i used my own scrip since i wanted to keep some apps and widget, after cleaning i had 114 system apps on my hox , Renovate rom comes with around 200 or so + the apps you'll install. (rom cleaner also improves the battery and rom speed a little) Other then that nothing else changed except i added tons of mods but thats up to you what you'll add. And the only setting you'll need to enable in Renovate rom is 2d rendering This improves alot scrolling times in apps especially the ones like *Advanced system care and Rom Toolbox lite*
Kernel settings:
Battery settings
the only thing you'll have to do manualy is switch the governor after flashing Xm kernel onto Smartmax And thats all you have to do to have great battery life, in my case i underclocked my CPU to 1200mhz with smartmax governor + RoW scheduler , if you want to keep it faster (but you don't really need any more speed with this governor) leave it as it is, or to make it even faster use Smartmax + deadline + sampling rate 30000 + touch poke freq 1500000 ] , you can make it even faster but trust me no need for that. Use this governor and it's settings as daily settings for light tasks and light usage of your phone.
Gaming settings:
For this you should be using interactive / gaming governor + deadline scheduler and that's all you need to do of course if you do underclock your CPU make sure you reset it back to 1500 after you change the governor , no need for apps that boost your phone, if you wanna make things even faster and governor more aggressive change this value in governor settings : go max speed load 45 this will increase speed ( remember this will make battery drain even faster ) , and if you wanna push max performance that your hox can deliver at current time change min frequency 1500 as well remeber THIS will make your hox battery drain fast as hell ! And sd card read ahead speed should be 4096 if is not set like this by default you can use system tuner and change it. For tuning governors and freqs you could use SetCPU easier and faster to do so.
Games that i used for testing are: NFSMW, MC4 , Shadown gun deadzone, Wildblood.
Each of this games were incredibly smooth and playable like never before.
Undervolting
Ok so as many of you heard undervolting should improve your battery life and it does by maybe 5% tops 10% if you're lucky.
But the main reason why i undervolt is so i keep my phone cooler when gaming you wont notice big difference in avarage daily use without gaming but with gaming you should notice the difference but again this mainly depends on your CPU variant, in my case i have variant 3 which means i can undervolt more then variant 2-1-0 , thats the only good thing about undervolting , of course i could overclock more then other variants but we don't need overclocking with this kernel and rom.
The difference and battery improvement you'll be able to see only this way really and none other this is how : without undervolting and lets say playing NFSMW my phone ON charger reaches around 55c TOPS ( which is overheating and you lose more battery then what your charger can recharge for you ) but with undervolting my phone is reaching TOPS 45C and avarage 40C ( this also depends on the room temperature and your hands body temperature ) The reason why i did tests on charger is because thats the fastest way to test overheating and undervolting and NO do NOT play heavy games while charging this is KILLING your battery and lowering it's life cycle ! it's like eating while sh1tting !!!
Now i can't tell you which values to use since like i said above none chip is the SAME nor the variant so you'll have to figure out this on your own but i can give you the ROUGH idea how-to.
Update - rough idea how to undervolt CPU properly:
ok i'll mark frequencies with colors:
Before we start remember this: Undervolting depends mostly on your ROM , Kernel , USAGE !
RED = Don't undervolt too much
BLUE = Undervolt normally as you do
BLACK =Don't undervolt or undervolt just a little this will depend on your variant and rom mostly
1500+ , 1400,1300,1200,1100,1000 e.g 1500mhz freq. has 1237mV by default if you're a gamer you can undervolt this one to lets say -50-100 (up to the variant) if you're not a gamer you can go even up to -125/150 , now this can depend also on which freq do you use the most in gaming lets say , if you're using quad lock e.g 1500 , -75 should be enough, === freqs under 1500 can be undervolted more since they wont be used, but if you don't use quad locking then you need to balance the undervolting between -50-100 (this depends on the game and which freq it uses the most)
860 , 760, 640 are the freqs in the *middle* those can be undervolted even more , up to -150 (default UV should be around -100 here) since they are barly used but you can use cpySpy to check which freqs your device uses the most and then use that info to balance your undervolting and find right freqs.
475,340,204,102,51 are the freqs more like *screen on standby freqs, mostly 340/51* or the LP core freqs, these should be undervolted MAX -50/75or not at all these freqs are used also for e.g. listening to music while screen off , if you undervolt too much you can experience laggs etc.
Important: Variant 3 can undervolt more then this but it *shouldn't* really up to you to decide
IMPORTANT: Those who use XM kernel USE TRICKSTER MOD APP ONLY !
First of all you can use guide what i made above for undervolting but since we have accurate undervolting now you SHOULD undervolt THIS way and this way only:
Variant 0 = you can use undervolting max up to -50 MAX ! or if you're doing step by step undervolting you might push some freqs -75
Variant 1/2: You can undervolt MAX up to -75 or at some steps -100 tops.
Variant 3: you can undervolt MAX -100/125 and on some freqs MAYBE -150 , but of course you need to do step by step.
Remember: this are the SAFE undervolting values for all 4 variants You can try undervolting more if you like but i wouldn't recommend it since i'm sure it will most likely cause issues for you.
Remember: The UV values i've used above are supposed to be *DEFAULT* uv you should use , but users with variant 0 MIGHT suffer and have to use lower values
Note: I guess 90% of ppl are lazy to mess with per freq undervolting and finding what works for them and what not since consumes alot of time, anyway you guys should be good with -50-75 variants 0, 1 ,2 , as for variant 3 you should be able to go up to -100-125 on all freqs.[/SIZE]
GPU - Undervolting - Safe values
[*]Ok so for GPU undervolting you need to be on XM #153 kernel and above and follow this steps:
Use some root explorer to enable GPU undervolting and navigate here:
sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage
Click to expand...
Click to collapse
, open it , the default value is
0 to enable GPU undervolting type 1
Click to expand...
Click to collapse
and SAVE make sure to enable *system as writable*
After you do that you need to download this app from playstore *Trickster MOD* This is the ONLY app whit which GPU undervolting works for now. After that install app and you'll see GPU freqs like this: For e.g. *520000, 484000* etc those are the GPU freqs and their voltage.
The safe values:
Variant 0 = -25MV on all freqs.
Variant 1/2 = -25/50 on all freqs.
Variant 3 = -50-100 on all freqs.
The 1st freq i wrote is 100% safe, the second is ASSUMED to be safe as well, but you wont know unless you try it :cyclops:
How to test are these values safe and wont freeze/reboot your phone.
Probably many of you know when you undervolt too much your phone eventually feezes and reboots this happens because phone can't give enough of voltage to the certain frequency that is in that time used mostly so it has no other way out but to freeze and reboot. and the way to test this is it *safe* is either to use *antutu bechmark app* , *epic citadel* or *stability test* Those 3 tend to push max performance very fast and easy out of your phone so if any app gonna show you is it safe it's these , tho sometimes but rarely your phone will run them both without reboots so i suggest you do each of them 2x just to be sure, and even if then sometimes very very rarely if your phone doesn't reboot the last way you could've find out is it gonna reboot is by playing NFSMW for 10mins.
----------------------------------------------------------------------------------------------------------------------------------
GPU Overclocking & underclocking - Safe freqs
For this to work use some root explorer and navigate here: sys/devices/system/cpu/cpu0/cpufreq/gpu_oc , open it there you'll see default GPU freqs like this: 520 520 520 520 484 400 304 267 247 those are the DEFAULT freqs on XM kernel and make sure to enable *system as writable* before you start doing anything. Those freqs are great balance for GAMING and BATTERY but if you're an ADVANCED USER you might wanna make those freqs EVEN HIGHER for better performance (not needed imo ) or LOWER for better battery life
- Maximum performance freqs that works for everyone: 560 560 560 560 560 484 400 304 247
- Freqs for battery life while keeping some poor performance (gaming speaking): 304 304 304 304 304 304 304 304 247
- Default freqs ( battery & gaming ): 520 520 520 520 484 400 304 267 247
Thx to Neo for this freqs.

GPU Voltage control:If you want to enable this you should write '1' to /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage.
In command line that is:
Code:
echo '1' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage

After that you need to restart your voltage control app (Trickster Mod).
Now you will see the GPU frequencies multipled by 1000 to separate them from the CPU frequencies. So you will see 520000MHz, etc.
Be advised that there are a really few HOX's that can handle more UV on Core, than the preset 50.
Also incrasing your Core voltage over 1300mV is NOT ADVISED AT ALL. Almost everything uses this voltage on your motherboard.
If you want to enable the values at boot, you need an init script that enables it, so later Trickster mod or anything can set them.

Viper X Rom 3.3.7 XM Kernel 139#[Beta]
Usage:
Somewhere between normal and heavy , battery life was great, not so much on the wifi this time, and all in all great kernel with one tiny bug, if you use autobrightness you'll see flickering , tho this got fixed in 147#. And i plugged the phone right before screen shots for maybe a minut to put pics on the pc and in the meantime i made those screenshots, you can see that in the usage. Brightness varied between low (15%) and maximum. The most used brightness used was 35%.
-----------------------------------------
-----------------------------------------
Black Pearl unofficial beta Rom 4.0.4 - XM Kernel 188#[Beta]
Usage:
- 1st of all , extreme undervolting and underclocking was done for this test.
- The rom and kernel were also flashed for the very 1st time.
--------
--------
================================================================================================
1st how PMC works:
Well simply i made it use as *ideal_freq* 340mhz , minimum freq is 51mhz , the freq you'll be using alot would be 340/475 , that is your main freq on PMC for boost to avoid huge laggs, another thing is it will try and use most of the time only 1 core unless that core is at 90% cpu load , and min cpu load is 50 to make sure you don't get frequent wakes of 2nd/3/4th cores.
Interactive PMC Version:
This version is 90% similar to PMC Battery setup except this version is much faster since it acts like INTERACTIVE Governor.
@ Those who don't have PMC Governor in their kernel until / if their kernel dev includes it use *Smartmax governor* for tunning and using my setup
Important ! : While setting your CPU/GPU values don't enable *Set on boot* unless the values are 100% safe for you and by ALL MEANS DO NOT USE MY CPU/GPU VALUES even if you're VARIANT 3 i wouldn't advise it , if you DO USE my values you will 99.9% end up in freeze or reboot !
GPU UV For max battery
2d GPU Underclocking: 304 304 304 304 267 267 267 200
3d GPU Underclocking: 247 247 247 247 247 200 200 200
As for GPU uV i'd suggest -50mv if you're not variant 3. Try first -25 then -50.
NOTE:
Don't even think about gaming with this setup , you'll notice laggs mainly at loading apps and speed of loading apps and mainly speed reduction overall in system , but not so much , the main slowdown is with loading apps and when multitasking you'll see some laggs as well, or for e.g. when playing music and then using volume up/down , that will lagg as well, if you wanna keep it *smoother* you can set *Ideal freq to 475000*
Performance may cry - setup v8a( XM Kernel 302# + ONLY or Kernels with latest Maxwens updates)
A This settings of PMC Governor should / will deliver you the performance 90% identical to Interactive governor with much much less battery drain ! , this settings can be / should be used for those who MULTITASK alot , this settings/governor should give you 95% lag free experience whatever you do except gaming ! [/I][/B]
PMC v8 INTERACTIVE SETUP for EVERYONE ( Xm kernel users don't need this since PMC governor is in the kernel by default with these values ):
awake_ideal_freq 475

Cpu freqs:
Min CPu freq : 51
[*]Max Cpu freq: 1100
[*]Scheduler: RoW
Multicore power saving : 2

Undervolting: At your choice and how much your variant can support:
Suggested SAFE values for all 3 variants NO GAMING for gaming use +25 more then my values under, example : if variant 1 is -100 NON GAMING , for gaming use -75.
This goes for both INTERACTIVE and BATTERY PMC setups.
variant 0 : -75
[*]variant 1/2: - 100 ( use -75 if you experience reboot )
[*]variant 3: - 150 / -175 in my case.

How to use FULL PMC setup.
Simple:
1st: thing to do enable 2d GPU rendering in developers options.
2nd: lower your CPU max freq to 1000mhz ! Yes 1000 mhz ( you wont feel much of a difference in terms of fluidity except when loading apps )
3rd: Use RoW or Sio scheduler ( for more info about these schedulers look at my signature guide theres explanation of every scheduler we use )
4th: Undervolt your CPU - here are the SAFE FREQS for these variants v0 - 50 , v1/2 , -75 , v3 - 100/125 (this are safe you could do more on some freqs)
5th: This is for those who don't play GAMES Underclock the GPU freqs here are the freqs you should use:
2d UC = 304 304 304 304 267 267 200 200
3d UC = 267 267 267 267 200 200 200 200
6th: Those who game you SHOULDN"T play with GPU UC only CPU UC.
Important: Make sure you use Trickster MoD app from playstore when using XM kernel for tuning and another vital thing to do is set in trickster app Multicore Power saving to 2 This will try to use as long as it can 1/2 cores unless desperate need for 4 cores.
A tip how to speed up loading times of the apps:
Since we have boost at 500 mhz if you open some app , lets say for example *Trickster MoD* after clicking on it you can hold your finger on the screen and move it in any direction , that way your CPU wont be locked onto 51 MHZ freq it will be on either 620 / 640 mhz ( boost freq ) or at MAX freq you set for CPU ( 700 if you use full PMC setup )
Final words:
PMC will try to force your phone spend 90% of the time in LP (low power) cores which barely use any power , if you do use PMC full setup the only real battery drain you'll have is your SCREEN and when in desperate need for some boost it will use your highest CPU freq you set.
Note:
Don't complain about bad speed etc etc etc , this governor is made only and only for BATTERY LIFE with basic usage.
And of course if this governor is *too laggy/slow* you can always use original *Smartmax governor*
NEW - SetCPU profiles setup balance v2 = SENSE =:
SENSE SetCPU profiles v2
This profiles fixed every little issue that exited in 1st release , just make sure to re-read the guide , some things has changed.
Anyway to make some kind of *changelog* if i can even call it like that this is what has got fixed / added:
Gaming works perfect now
Added profile for 2d games
Added profile for safety ( over heating to prevent it 2 steps )
Added more apps into profiles
Changed freqs on some things for better performance/battery life
Some other stuff i can't remember right now lol

Q) What does this do ?
A) Makes your phone smarter , boosts it when needed and downscales CPU freqs when not needed , It changes Governor / scheduler / CPU Freqs / .
Improves Loading times alot vs old PMC setups. The default loading times speed varies between 1100 mhz and 1300 mhz now.
Example:
Sense launcher: is set to use 640 MAX Cpu freq with smartmax governor + SiO scheduler.
Messaging: email / sms / gmail / etc = It will switch governor to PMC v7 ( Interactive version ) Boost max CPU freq to 840 and use Deadline scheduler so it makes sure it's liquid smooth and rotation works perfect.
Gaming: When you hit some , in my case NFSMW , MC4 , RR3 it will change to interactive governor + Row Scheduler and use MAX Cpu FREQ 1300mhz.
HOW TO SETUP ( Important ! )
1st: download SetCPU ( google it if you can't buy it you should be able to find it for free)
2nd Set max CPU Freq to 1300 and min freq to 51
3rd: Go to trickster and do the following:
Trickster settings:
PMC Governor = Leave as it IS
Scheduler = SiO
Multicore power saving = 0
Gpu Max freq = 520
Smartmax Governor settings = Change the settings to PMC V7 BATTERY Settings ( This is important thing to do if you want the profiles to work )
Undervolting - UPDATED:
Variant 1/2 = freqs 51/1250 undervolt - 100 ( if is unstable for you use -75 ) Freqs 1300-1500 Undervolt - 50 ( if is unstable use -25 )
Variant 0 should use 25mv more compared to v1/2 and variant 3 can do additional -50 on freqs 51/1250 and 1300/1500 freqs -25 compared to variants 1/2.
And last thing to do is *Set on boot / enable* - Do this only if UNDERVOLTING doesn't cause any reboots for you , it shouldn't anyway.
4th: copy my SetCPU Profiles to your SDcard and open SetCPU App , load the profiles and Apply them , make sure to tick * Enable Profiles * Also on the *MAIN* settings for CPU / Governor / Scheduler tick *Set on boot* and finally @ *Governor* also tick *Set on boot & Set With profiles*
5th: Download greenify app from playstore:
Set greenify app at your likings but make sure you don't put Trickster and SetCPU Apps in there.
6th: Downlaod LagFix (Fxstreem) App from playstore as well. Use this app once a day or whenever you like it.
Note: This will work ONLY With XM kernel unless another kernel dev includes PMC Governor in their kernel.
Tips:
[*]New - for MAX Speed when not using apps listed in profiles set in trickster & SetCPU Max Freq 1300 ( For absolute max performance 1500 ) min 51 INTERACTIVE governor and DEADLINE Scheduler. What will this do: Well simply it'll use max freq 1300 / 1500 depends on your choice whenever you're using something that is not listed in the profiles E.G. when you hit *Settings* it'll use interactive + deadline , same goes for other things that are not listed in the profiles.
[*]If you do full reboot make sure to open SetCPU app so profiles start working after the reboot.
[*]For 2d games *temple run* Etc just add them into *2d gaming profile*
[*]Tip for heavy 3d games sucha are Mc4 NFSMW , RR3 etc etc , i've set on 1300 max CPU freq so we avoid heat etc , note that those games are on MAX DETAILS for me and i don't have laggs so you guys who use those games without those details you should be fine in fact you can change max freq from the profile onto 1200 if you like. If you play some other 3d heavy games just add them in *Gaming* profile.
[*]A Tip for gaming with low details: Change the max freq from my profiles to 1100/1000 , i played NFSMW on max details with some FPS Drops on 1000mhz freq.
[*]@Those who use more social apps then facebook , simply add those apps in my profile where is facebook. If you use another messaging apps simply add them to my messages profile. Do the same to the other apps that you use which are similar to the apps in my profiles.

@Those who don't game at all and want maximum battery life they can get , also this would be useful for those who game as well , just apply those 2 things after you done with gaming:
Go to trickster app and do the following:
Max Gpu speed = 416
Multicore power saving = 2
If you want even more battery life visit my signature theres everything else you need to know on the post 2.
IMPORTANT: I've set on every profile *Notification* just so you guys can see it does it work , for those who want to remove it simply do this:
SetCpu > Profiles > click on the profile > Next > Untick *Show a notification* and that's it , do the same for other profiles.
Click to expand...
Click to collapse
If by any chance you don't see notifications after first time applying my profiles make sure you enable *Set on boot * where ever i wrote above and reboot your phone. That should fix it.
If anyone experience any issues ETC please lemme know.

Note:
You shouldn't really relay and trust benchmarks at least not in antutu and quadrant , the most reliable and most accurate benchmark we have is Epic citadel , almost every single time same results. and 52.6 is quiet high result for sense rom. Btw for those who care s3 scores average 44-45fps on epic and note 2 scores average 46-47fprs.

ADDITIONAL INFO - UPDATE:
I tought it would be nice to add some info about schedulers , and governors so ppl better understand what they are and what they do
Update: added governor info.
Update: added info about MpDecision and Cpu Quiet per request..
---------------------------------------------------------------------------------------------------
Governors:
- OnDemand Governor:
This governor has a hair trigger for boosting clockspeed to the maximum speed set by the user. If the CPU load placed by the user abates, the OnDemand governor will slowly step back down through the kernel's frequency steppings until it settles at the lowest possible frequency, or the user executes another task to demand a ramp.
OnDemand has excellent interface fluidity because of its high-frequency bias, but it can also have a relatively negative effect on battery life versus other governors. OnDemand is commonly chosen by smartphone manufacturers because it is well-tested, reliable, and virtually guarantees the smoothest possible performance for the phone. This is so because users are vastly more likely to ***** about performance than they are the few hours of extra battery life another governor could have granted them.
This final fact is important to know before you read about the Interactive governor: OnDemand scales its clockspeed in a work queue context. In other words, once the task that triggered the clockspeed ramp is finished, OnDemand will attempt to move the clockspeed back to minimum. If the user executes another task that triggers OnDemand's ramp, the clockspeed will bounce from minimum to maximum. This can happen especially frequently if the user is multi-tasking. This, too, has negative implications for battery life.
- Performance Governor:
This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task, such as syncing email, and returns the CPU to the extremely efficient low-power state. This still requires extensive testing, and a kernel that properly implements a given CPU's C-states (low power states).
- Interactive Governor:
Much like the OnDemand governor, the Interactive governor dynamically scales CPU clockspeed in response to the workload placed on the CPU by the user. This is where the similarities end. Interactive is significantly more responsive than OnDemand, because it's faster at scaling to maximum frequency.
Unlike OnDemand, which you'll recall scales clockspeed in the context of a work queue, Interactive scales the clockspeed over the course of a timer set arbitrarily by the kernel developer. In other words, if an application demands a ramp to maximum clockspeed (by placing 100% load on the CPU), a user can execute another task before the governor starts reducing CPU frequency. This can eliminate the frequency bouncing discussed in the OnDemand section. Because of this timer, Interactive is also better prepared to utilize intermediate clockspeeds that fall between the minimum and maximum CPU frequencies. This is another pro-battery life benefit of Interactive.
However, because Interactive is permitted to spend more time at maximum frequency than OnDemand (for device performance reasons), the battery-saving benefits discussed above are effectively negated. Long story short, Interactive offers better performance than OnDemand (some say the best performance of any governor) and negligibly different battery life.
Interactive also makes the assumption that a user turning the screen on will shortly be followed by the user interacting with some application on their device. Because of this, screen on triggers a ramp to maximum clockspeed, followed by the timer behavior described above.
- Suggestion : Use this governor (Interactive) for GAMING , it's the best when using Xm kernel for this purposes +deadline or Row scheduler.
- Smartmax
Long story short if you want crazy battery life USE this governor with either noop/sio/row governor, depending on what you want , read about schedulers under and chose what fits your needs.
- PMC ( Performance may cry )
ok so i made this governor based on Smartmax except it's heavily tweeked for better and maximum battery life you can get out of HOX.
- TouchDemand:
This governor pretty much do what the name says, boosts cpu freqs by touches, this one actually can be pretty great for battery life if you underclock the CPU imho and use max 2 cores, you can do that by doing this: edit touch_min_cores under governor tuneables and set 2
Anyway i still prefer *SmartMax* for battery life. But up to you to test and find out.
As for other governors like : Conservative and powersave , i wont be adding info about them since i doubt anyone ever uses them , all they do is take more space in the list
-----------------------------------------------------------------------------------------------------------------------------------------------------
Schedulers:
- Noop:
This scheduler assumes I/O performance optimization will be handled at some other layer of the I/O hierarchy , on the more simple way this scheduler is MOSTLY used for battery life since it's slow - it raises freqs slower then other schedulers.
- Deadline::
This scheduler attempt to guarantee a start service time for a request It does that by imposing a deadline on all I/O operations to prevent starvation of requests. It also maintains two deadline queues, in addition to the sorted queues (both read and write). Deadline queues are basically sorted by their deadline (the expiration time), while the sorted queues are sorted by the sector number. To make it more simple this scheduler raises freqs much faster then noop and keeps them longer active then noop which means more battery drain ( not by much anyway ) and faster I/O as well the gaming should be the best with this scheduler.
- SIO:: - ( my favorite )
This scheduler in simple words is basically this : It's a mix of noop and deadline schedulers , noop is more for battery while deadline is more for performance , and sio is perfect balance between them ^.^ to be more specific it's more like almost having noop+deadline activated at the same time.
- ROW::
ROW: stands for "READ Over WRITE* The ROW scheduler is in favor for user experience upon everything else (means it should make things stupidly smooth ),so that why ROW scheduler gives READ IO requests as much priority as possible. Usually it¡¯s a single thread or at most 2 simultaneous working threads for read & write. Favoring READ requests over WRITEs decreases the READ latency greatly. == Even more speed.
The main idea of the ROW scheduler is // == If there are READ requests in pipe - it WILL dispatch them but don't starve the WRITE requests too much.
Also this scheduler is much better optimised for our phones since in the smart phones we use flash memory and not hard drives.
Finally : Think of this scheduler as a mix OF deadline+ Performance governor put in scheduler while you can use another governor e.g. Smartmax. It's quiet fast scheduler and even good for daily usage without much of impact on the battery life.
Hope this prevents the question about schedulers / governors and which one to use
And a tip: Sio scheduler should be PERFECT with smartmax governor for battery life + speed , in fact it's the best scheduler if you guys want speedy performance while saving the battery life.

MPdecision:
MORE INFO >
For us mpdecision is a cpu hotplug system, which replaced the default nvidia hotplug system. It was written by showp1984(Dennis Rassmann).
It's more configurable, better for battery life, and much much better for gaming.
Cpu quiet:
- Cpu quiet driver regulates the cores by them acting more syncronized. they scale up n down in a more uniform fashion. therefore it gets better battery life without losing performance. You can't manage each core like with morrifics. so the cpu quiet driver is doing all the regulating. So the cpu quiet driver basically replaced hotplugging as far as cpu core management goes.
- In simple words it should give better battery life.
Good thread mate!
I know people have been looking for a guide for ages.
Goku was gonna do one in fact, guess you beat him and me to it.

Lol thx, i was actually waiting for you or him to make one, i guess i got tired of waiting and besides that i saw tons of questions in past few days about *which kernel , rom* are the best so i guess they have their answer now.
Oh and if you have anything to add that i might forgot or anyone else please feel free to do so.
Edit - I'll probably add new screenshots when i manage to waste this 9% i got left, this battery refuses to die, i feel like i have note in my hands lol.

I'll have a think, I've got a little battery guide of my own that I wanted to write.
I'll have to see if wilky will want to put it in the OP, if not then you can use it in this thread.
Also I'll talk to wilky and see if he wants to add a link to your thread when we next edit the OP.

Yeah i did use your repack cuz of original s2w Also cuz of Smartmax as default on boot. thx for that.
Btw OP updated with final battery results. Ppl i think we have the perfect match here about battery + gaming + speed. It's simply revolution of HoX. And all thx to everyone who developed for HoX sucha amazing stuff, and we must not forget things can get only BETTER for hox from now on not worse, so we might expect even better stats.
Just a small comment on smartmax
Setting boost_freq has actually not much of an effect
This is only used for the "external" boost interface of smartmax
This can be used e.g. from the android power module to boost
the cpu if required. But thats of course not implement in most roms
So only touch_poke_freq has an effect since this is use to boost
on input events from the touchscreen

Hello , for changing the governors and schedulers undercloking , overclocking and changing the governor values i use SetCpu you can find it on apkmania site, as for undervolting and further more tweeking i'm using System tuner , you can find that one on the playstore. Btw it's in the Op

Re: The ULTIMATE BATTERY LIFE+ GAMING PERFORMANCE setup/guide
Thnks shang, will try it in SkyDragon rom to see how it works, as Base 3.17 its better, hope to get better results,
Btw.. Kernel Devs makes our roms better.
Cheers
SkyDragon Team© No Kangy rom allowed.
Ok so I am experimenting with Set CPU app
Can you guys tell me what Profiles you run or prefer
Thanks

I don't use SetCPU (way over complicated for no good reason) but Kernel Tweaker. With my experience on the F4k kernel:
JB - Interactive
KK - Smartass V2
IO Scheduler: normal phone use ROW. If you have some regular write operation, CFQ. I've tried SIO, ZEN and NOOP, overrated. While NOOP and ZEN feels really responsive (like mininium lag) but it unstable. As for SIO I don't see what people see in it. It not particularly faster, and nor battery friendly. At least that what I saw on my S3 with Pegasus governor. And I don't use benchmark, this is a pure observe from normal day-to-day use on open app, multi-tasking, browsing, etc. I've tried all mention governor for at least a week.
As for UV, I've done -1.5V (yes, not a typo) on my phone. Again, I don't bench or play games, just regular day-to-day email, browsing, photo, etc.
I'm on JB 4.2.2 Stock and using SmartAssV2 + ROW. Max freq. on 2.05Ghz. Working fine so far.
Check out this thread: http://forum.xda-developers.com/showthread.php?t=2686845 for undervolting results part (I'm guessing it's in your SET CPU too).

I'm using f4ction kernel 1.3.0 with 90hardlimit_2.05Ghz.zip flashed after the kernel with TWRP.
Also, i like CPU Control, which is very easy to use.
I don't need set cpu anymore. I turn on air plane mode at night so battery life can be longer.
And checked on cpu's cores, system automaticly control frequences.
Using SetCPU the Charging with USB takes ages
Do I need to set a profile as I have tried other apps to change stuff but this seems to be the only option for me with a modified Stock Rom
Have used these settings so far with no lags or issues .. can someone pease clarify if this is ok...
SET SCREEN OFF
CPU - 810 - 384 Gov: Interactive / Priority 100
SCREEN ON
CPU - 1566 -384 Gov : OnDemand / Deadline / Priority 52
BATTERY <45
CPU - 1026 - 394 Gov: OnDemand / CFQ / Priority 50
SLEEP 00:45 - 08.25
CPU - 584 - 384 Gov: Powersave / CFQ / Priority 49
What about Battery or CPU Temp?

Powersave governor is a governor that locks on the lowest possible speed provide by the kernel. No point on setting a speed range since it doesn't dynamically switch between them.
Well as I mention above, I don't recommend using schedule beside ROW or CFQ. If anyone still thinks SIO, NOOP, Deadline is significantly faster/better than CFQ this is a very interesting test: http://www.phoronix.com/scan.php?page=article&item=linux_iosched_2012
