[MINIGUIDE][CM7|Stock] V6 Supercharger for the 2x (Smoothness & Snappyness)

.
Attention: This guide is for an older version of the V6 SuperCharger.
This doesn't mean that you can not use this guide as a reference or interesting read, but the new script has some more options which aren't covered here. You have to read the instructions within V6 carefully.
I did a lot of testing some weeks ago and now that I finally have some time I'd like to share what I got so far.
The V6 Supercharger is a tweak skript by zeppelinrox which works really great on my 2x. It feels smoother and snappier than ever - and multitasking is damn fast (and I never felt that CM7.2 was unsnappy.. but there is a difference now).
I won't talk a lot about what it is and how it does work - read the original thread. It has an even better effect on low spec phones, but it does improve the snappyness on high-end phones, too (and is even used on Samsung Galaxy S II and Galaxy Nexus phones!)
[Script][MOD][U9RC6.1] Sticky 'n Smooth ISCream-=V6 SUPERCHARGER!=-The ONLY RAM Fixer
All credits go to zeppelinrox for this great script!
Here's a quote for what it does:
zeppelinrox said:
What's it do?
It makes your phone FAST... super snappy with better multitasking!
It rearranges and fixes the OOM Groupings and Priorites and lowmemorykiller values.
So basically, it's a COMPLETE MEMORY MANAGEMENT FIX!
It's the ONLY one of it's kind
NO LAUNCHER REDRAWS, faster than ever, multitasking is better... why?
Because it works with the lowmemorykiller and letting it work the way it's meant to work.

Warnings:
This is not for ICS! Go to the 2nd post in the thread linked above - there are instructions for ICS (CM9) - I don't use CM9 yet and don't want to include instructions here, which I haven't tested thoroughly.
You shouldn't use this with custom kernels (like vadonkas) I guess - it might break some tweaks from the kernel devs.
I tested this with CM7.2 (temasek KANG) with the stock CM-kernel and it is working GREAT! It should make an even greater difference on Stock - please report!
I tested lots of options and never had a single problem.. but you should do a nandroid backup! There is always a slight chance that something goes wrong.

Instructions:
(type all options without quotes.. I hope that's obvious)..
Go to Settings - Cyanogenmod - Performance and make sure that "Lock home in memory" is not checked. If it is: uncheck it and restart (don't worry, the tweak will take over with a better solution than a permanent lock in memory).
Download the "V6_SuperCharger_for_Android-update9_RC6.1.sh.txt" from the original thread or from the attachments here and put it to the root directory of your SD card.
Open "Terminal Emulator"
Type "su" (and approve the Superuser request)
Type "cd /sdcard"
Type "sh V6*" (this is cAsE-sensitive)
The first time "wizard" will guide you through the installation process.
for the scrolling speed "2" is a good choice for the first time
type "b" for the build.prop option
type "y" to integrate /init.rc
I disabled the "AWESOME" animation (type "y") because it would get annoying after waiting for it to finish after the 3rd time.. sorry for that zeppelinrox
press the enter key
now type "10" (Quick V6 Custo-OOMizer option)
type "y" to use the calculated values
press enter twice
type "29" to reboot and wipe dalvik cache. The restart will take a while, be patient, that's normal!
that's it!

There's a "quick walkthrough" in the second post - together with the best options (at least for me) for the older update 8.
Again: All credit to zeppelinrox - he has a donation link in his thread! If you like it, donate to him please

Quick walkthrough - commands only (update 9 RC6.1):

------------------
Instructions for the "older" update 8:
Go to Settings - Cyanogenmod - Performance and make sure that "Lock home in memory" is not checked. If it is uncheck it, restart the device and recheck
(don't worry, the tweak will take over - I didn't have a single launcher redraw).
Download the "V6_SuperCharger_for_Android-update8.sh.txt" from the original thread or from the attachments here and put it to the root directory of your SD card.
Open "Terminal Emulator"
Type "su" (and approve the Superuser request) (without quotes.. I hope that's obvious)
Type "cd /sdcard"
Type "sh V6*" (this is cAsE-sensitive)
Type "0", "1", "2", or "3" to set how fast the text will scrool. "2" is a good selection for the first time.
Choose "9"
Type "16" (your device will restart without further warning!)

Sorry.. I wrote that because I pressed "Submit New Thread" accidentally before the post was ready. It's up now

there is already a update 9, which works perfect on the speed, but I don't see great improvements between Chuck Norris Edition with and without V6. Think Chuck Norris is already so awesome.
P.S: really easy to set up, just download Script Manager from the Market, open it, click on SU and open up this Script, everything else will be explained through the MENU

Has anyone tested this with the latest vadonka's ETaNa yet?

I know it's not ready yet, but I'm already psyched about it :-D
I already have a question about it.
If I run this skript is it suggested to change minfree values?
I have mine set on 16-24-32-90-100-110 right now. Thats pretty heavy I think, but Setiron suggested those values.

Yup but update 9 is still a RC. I know it's pretty stable but haven't tested it yet, will do that over the weekend and update the instructions if everything works fine.
You're correct - the Chuck Norris ROM does use a lot of tweaks, too - this is mainly focused to non-tweaked CM7 and Stock ROMs

Great... I include always it in my rom...
Inviato con il mio P990 DjangoManouche!

Wow, thanks very much, my device feels superfast right now!
Do i have to repeat this procedure everytime i flash an cm update, e.g. a kang?

this script only advantage the bulletproof/hard to kill launcher for as, but since the o2x is a highend phone the launcher reload fast, probably dont even noticed that and if you have a memory hungry launcher probably not a bad thing if this is not stuck in the memory, so its not really necessary this. bulletproof the launcher is good thing in an old phone like moto milestone (this script originally made for that phone by the way)
the memory management is not so good, the autokiller memory optimizer app do a much better memory management and its user friendly.
also this script minfree values is not optimized for the o2x.
I'd rather not use overall, but its your choice guys

I cannot agree in all points.
First of all V6 won't lock the launcher in memory (unlike the CM method!).
Then it will tweak more aspects in terms of memory management than just the "harder to kill launcher" - more on that in the official post. Last but not least - the phone is a highend one, but it lacks some memory (1GB would have been great). And it seems that it does help quite a lot, here.
But of course you're correct that it might not be the "best of all" solutions for the 2x - but I can feel quite a difference while using V6. For Stock LG and CM7 it seems to be a good enhancement - I don't mind if people here use it or not, I'm really happy with this solution right now. Just thought might be worse sharing as there are many threads for V6 for other phones (even the SGS II!!), but not for the 2x.
Just my 2 cents.
P.S.: I havent tested your newest kernel with the tweak scripts - maybe it will even blow me away more if the values are more optimized for the 2x

btw I'm sure you are totally unfamiliar with the newest incarnations where the values are calculated according the ram available on any device.
SO IT"S ALWAYS OPTIMIZED FOR THE DEVICE IT'S RUNNING ON.
If anything, bulletproof is BETTER suited for devices with more ram - since they can more easily do this without detrimental effects since they do have more ram.
Nothing you say adds up.

look, your script working superb on my old milestone, when i write this post what you quoted here i had the milestone not the o2x. but with o2x honestly i dont think its necessary to tweak so many memory management part. the phone have enough memory to handle most of everything and have a fast dual core processor.
i use only this:
echo 0,1,2,4,6,15 > /sys/module/lowmemorykiller/parameters/adj
echo 1536,2048,4096,15360,17920,20480 > /sys/module/lowmemorykiller/parameters/minfree
i dont see the point of the other stuffs
lock the launcher in the memory is also not necessary, its reloaded fast i dont even noticed that every time.
but its just my opinion
ps: you are using this file in many procedures: rcpath="/system/etc/rootfs/init.mapphone_umts.rc"
this isn't exsist in the o2x rom.
for example:
sed -i '/ro.EMPTY_APP_ADJ/ a\
setprop ro.FOREGROUND_APP_MEM '$SL1 $rcpath
this is only work if the rcpath=/system/etc/build.prop and cut out the 'setprop' string (/data/local.prop also not good for as). i also found some code what is not working with the o2x rom. the whole script is for the droid/milestone's. at least what i found in this thread OP

Try the newest one
http://forum.xda-developers.com/showthread.php?p=22689090&posted=1#post22689090
init.mapphone_umts.rc isn't even mentioned.
Instead, it does a search for the appropriate file.
It's vastly more sophisticated than Update 8 in all aspects.
The 0,1,2,4,6,15 is kinda useless... no different really than the default 0,1,2,4,7,15
There is a fairly new supercharger thread for the new Galaxy Note... they see a clear difference.
So you really won't ever know until you try

okay, this version it seems better: V6_SuperCharger_for_Android-Update9_RC6.1.sh

Yeah there isn't much difference between that and the one I linked to above if you're on CM7.
The incremental update was an ICS detection fix.
I may have all 4 scripts updated today tho

Hey zeppelinrox, do you recommend to change minfree values when using the v6 script?
I'm running CM9 with Ironkernel and mine are set to 16-24-32-90-100-110, but I think thats a little extreme. Setiron suggested those values, because ICS needs more ram.

[CM10] (5Feb13) NC Performance (and) Placebos

After getting a little annoyed at the runty, poorly mapped-out, scratchy thicket of real and imagined performance tweaks, I decided to embark on a semi-long term project to determine what's real and what's "zomg mega-booster performance pills".
First project was to evaluate existing performance options on stock CM10 for actual gains using experimental design. (tl;dr: for those geeky enough to want to know, it was a main effects only d-optimal design with 32 design points for the 16 parameters listed, including several lack-of-fit and pure-error replicates. I could go on, but do you really want me to?). I ended up with a list of 16 parameters all together, from the Developer Options and Performance settings, based on their showing up in various performance tweaks discussions.
The main challenge was finding a way to measure actual performance instead of perception. I settled on several benchmarking tools: Antutu, Quadrant, SQL Benchmark, and Chainfire's benchmarking app. One of the parameters being tested ("don't keep activities") actually breaks Antutu at the graphics testing step, so I'm not reporting anything from Antutu.
All told, out of the 16 parameters tested, only 9 showed any kind of effect whatsoever, and combining best settings for all 9 simultaneously, total performance only boosted by ~20%, of which fully half was due to switching max speed from 1000 to 1100. this means the other 8 settings combined for a total boost of ~10%, meaning individually they're peanuts. The remaining 7 settings that showed no effect are only so much fluff and unlikely to do a thing for you performance-wise.
Results are summarized below for your reading/teeth-gnashing pleasure:
Max Speed (1000 versus 1100): Very clear, notable difference between the two settings on all benchmarks. This is the expected result, about 10% improvement in all benchmarks on average. Recommendation: set max speed at 1100.
Governor (convservative vs interactive vs ondemand): This only had any impact on Quadrant benchmark, no other benchmarks appeared to care. In Quadrant, conservative was the worst overall, while interactive provided an ~ 5% boost and ondemand gave ~6% boost. Recommendation: use ondemand.
Scheduler (BFQ, CFQ, noop, deadline): I don't know what schedulers do or the differences between these settings, but the only place they had any effect at all was in the SQL benchmark. There were clear differences here though: BFQ was by far the worst. CFQ and deadline were about the same with a 17% increase in SQL activity performance. noop was the best with ~ 20% increase in SQL activity performance. Recommendation: use noop. [update: some have reported stability issues with noop. If thus us the case for you, CFQ would be the next best choice]
Zram (disabled, 18% default, 26%): Zram effects only showed up in Chainfire's benchmark app, specifically for Java activities. Default 18% setting performed worst but disabled setting wasn't significantly different. 26% setting gave a 4% boost, but again, only for the java-specific benchmark. Recommmendation: use 26% setting.
16-bit transparency (off or on): Turning on the 16-bit transparency setting gave a smallish 3% boost to Chainfire's java benchmark. It did not have a measureable effect anywhere else, and I did not visually see any differences anywhere during testing. Recommendation: turn on 16-bit transparency.
Kernel same-page merge (off or on): This had a *negative* effect when turned on, resulting in a 1% performance hit on Chainfire's native benchmark. It did not have any measurable effect anywhere else. Recommendation: Keep off.
Don't keep activities (off or on): This was very problematic: it provided a distinct improvement in quadrant score (+8%) when turned on, but behaved poorly with other apps (Antutu being one). Since it didn't seem to help anywhere else outside of Quadrant and didnt' play well with others, recommendation is to keep off:
The following list are the settings that had no measureable impact anywhere. Any attempt to claim they have "zomg" status should be summarily whipped with placebo pills, or else they should let me know the exact details in which they supposedly work and I can test.
Placebo hall of shame:
Surface improvement (since it had no effect anywhere, why not just set it on banding/blur and have the best pictures?)
Background process limit
Disable HW overlays
Force GPU setting
Any of the animation scale settings (although they look snappier at lower settings, so it at least *feels* faster)
minimum speed (seriously? people think this has an effect? keep at 300 for best battery life)
Allow purging of assets
Hope you like this, y'all! Let me know if there's any other mad-scientist experiments you'd like to see.

Nicely done. How many times did you run each test? Or perhaps the results were very consistent.
FYI; regarding the governor, scheduler and the like, you may want to have a look at this thread;
http://forum.xda-developers.com/showthread.php?t=1369817
I think gives your tests / results some perspective as well.

Thanks for the link. Very informative.
How familiar are you with factorial designs? All parameters were tested simultaneously in such a way that their individual effects can be partitioned out mathematically. That's what allows me to test all those settings with just 32 runs and still get solid estimates of their effects, and more importantly, the amount of variation around them (a requirement for distinguishing real effects from noise).
I suggest googling "factorial design of experiments" if you're interested.

Re: [CM10] NC Performance (and) Placebos
Good suggestions. Before trying these third party tweaks would be good to know a few things from actual users:
Has anyone tried any combinations of these tweaks simultaneously? If yes, did they all play well together? If no, details please!
Some of these appear to have device specific settings, can anyone share settings being used on the NC?
I intend to sandbox these, as i have little desire to use then in real life just yet. Can anyone confirm that if i restore my current setup, the restore process will clean out whatever settings these tweaks out in place?
Speaking for all scientists, thank you kindly!

Have only used V6, from my experiences, restoring a Nandroid or flashing a new nightly will clean out everything it changes other than the files you store on the SDcard. This post details how I set it up http://forum.xda-developers.com/showpost.php?p=34991382&postcount=1234
I never really noticed a huge performance boost from V6, it did reduce the lag that was in the Beta's and early nightlies, mostly seemed to keep memory available and avoid the lag issued in the early builds. Have not used for the last few weeks since performance has improved on the newer builds.

Re: [CM10] NC Performance (and) Placebos

Thank you!
Thank you for your measured and logical approach and recommendations! It is appreciated. I have experimented a little with the third party tweaks and haven't found any that fascinating, honestly.
When I install CM10.1, I also flash a script I made to customize to my preference and delete stuff I don't use like language modules, ringtones, quicksearch, boot animation, etc to free up some RAM. Between that and killing memory hungry apps when I'm done, my old Nook is still holding on reasonably well.

Got to tell you, your suggestions on settings are paying off. My nook is smooooooth. Is working ok there is sometime that lag liittle bit, but my p3113 also doing the same. I will stay with this 0120 nightly for a while with your settings on perfomance. .

I'm surprised that zram enabled IMPROVED things. So between disabled, 18%, and 26% (no idea what default really is without digging in the code), 26% was the best option?
Interesting. I thought zram would improve multitasking (maintaining background activities) at the expense of potential slowdowns (compressed swap to ramdisk).

It might have that effect, but wasn't apparent in the benchmarks i used. It could be that a different benchmark is needed to detect it, or it could be the negative effects are too small to be measurable compared to the normal "noise" of operation.
Any ideas how we could measure this more explicitly, if there is any interest?

Good question, I'd think it'd require some way to switch activities around and somehow measure their switch rates, but the environment would be quite difficult to keep consistent.
BTW thanks for the scientific work on this stuff, MUCH better than "OMG THIS TURNED MY TABLET INTO A UNICORN" posts we see a lot on tech forums.

Since it would help most when memory is low (like it ever isn't), running two memory hogs simultaneously should show an effect if there is one. A custom memory-hog app built under two different names, perhaps?
I have a shell script that creates a swapfile and enables its use that would also be well tested this way, since zram creates an in-memory swapfile. I was never able to see any tangible results except for the output of "free", so I don't use it anymore, and haven't tried it under CM10.1.

Please help: big lag issue

Guys, I need a help. Tried everything, but still facing big lag especially when I click on dialer, contacts or messages (waiting couple of secs until they show up). This is more obvious when I click right after I 'woke up' my phone from deep sleep.
I'm using stock 20b with Iodak v8 kernel (tried v9 as well, but due to bluetooth and fm radio issue on stock, reverted to v8). Also, I did everything what I could found to improve performace: disabled and then deleted MLT, did a full wipe of everything (clean install), installed only apps that I need, turned off 3g, data and gps (only WiFi is on), installed Greenify and so on..
My current setup of kernel is following:
Governor: interactive (tried ondemand, but was even worst)
Max: 1600000
Min/Max Screen Off: 760000
Scheduler: SIO
CPUQuiet Power: userspace (noticed that only 3 cores are online instead of 4)
I appreciate any help, but please, don't tell me to search, 'cause I did. As for the other custom roms, I tried CM, but I prefer more stock, mostly because of Gallery, Polaris and FM Radio Apps.
Guys, is there any way to fix this lag issue? I don't care much for the battery, since this lag drives me crazy.
Thanks in advance.

Guys, I need a help. Tried everything, but still facing big lag especially when I click on dialer, contacts or messages (waiting couple of secs until they show up). This is more obvious when I click right after I 'woke up' my phone from deep sleep.
I'm using stock 20b with Iodak v8 kernel (tried v9 as well, but due to bluetooth and fm radio issue on stock, reverted to v8). Also, I did everything what I could found to improve performace: disabled and then deleted MLT, did a full wipe of everything (clean install), installed only apps that I need, turned off 3g, data and gps (only WiFi is on), installed Greenify and so on..
My current setup of kernel is following:
Governor: interactive (tried ondemand, but was even worst)
Max: 1600000
Min/Max Screen Off: 760000
Scheduler: SIO
CPUQuiet Power: userspace (noticed that only 3 cores are online instead of 4)

This is "normal" for system apps. Download custom apps from google store like ExDialer,GOSms.. That will resolve your lag.. When you install those apps from store, use titanium backup to freeze stock apps(dialer,contacts,messages).

Thanks guys, but neither of these two options helped. There's some improvements, but still pretty much laggy.

Think I found out what causing lag: synchronization. Every time when phone is synchronizing, everything is so laggy, otherwise is ok. Following accounts have sync turned on: Skype, Facebook, WhatsApp, Twitter and Google.
Does anyone of you have experienced similar problem? Is there solution for this?

I have all those apps running in my phone, but I did not face those lags.
But ya I did felt those lags when I'm still using stock JB OS. Stock JB from LG is sucks man, you should instal another ROM.
Currently I'm using CM11 (Kitkat 4.4.2 based), its lag free and have more free RAM. (around 350 - 400MB). :good:
The difference is like heaven and hell compared with the stock ROM (I only have 150 - 200MB Free RAM).

The ROM can make a difference, but it has nothing to do with "Free RAM". I wish people would stop perpetuating this myth.
Free RAM is wasted memory on an Android device. Unless you are getting below about 50MB there is not a problem as the device is designed to use as much as it can and then swap it out automatically.
I agree about CM11 though. I'm running the latest nightly and the only problem I have is the delay in waking when you press the power button

RAM: What it is, how it's used, and why you shouldn't care

Well, I’m afraid that I’ll be forced to get back to CM (used it once, but missed some apps such are: FM Radio, stock gallery app (couldn’t find good replacement that synced photos with google acc) and Polaris Office – these apps I use on a daily basis). Anyway, before install CM, I’ll give one more try to Stock.
I did what @ottomanhero told me, and that actually helped. But, since I used Trickstermod to tweak governors, after every single reboot, stock values would be back, so I had to use init.d script, and there comes a problem.
Here is what I did (followed instructions from Iodak's OP):
- Using ES File Explorer created folder /system/etc/init.d and set permissions to rwxr-xr-x
- Created new file in init.d folder and name it 1script (used Note++ instead of Windows editors to avoid leaving an extra space at the end of each line or an invisible invalid character)
- Then added following commands:
Code:
#!/system/bin/sh
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/midrange_go_maxspeed_load
echo "60000" > /sys/devices/system/cpu/cpufreq/interactive/min_sample_time
echo "20000" > /sys/devices/system/cpu/cpufreq/interactive/timer_rate
echo 200 300 400 450 500 600 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_overclock
- and finally set permissions to 1script rwxr-xr-x and owner to root group to shell
So, that should be it, but didn’t work for me. Then, I installed SManager to check what’s wrong with the script, and it stated that with first 4 lines error is: no such file or directory (which is strange because exactly that's the path), and for the last line is stated: permission denied.
Did I miss something? Apologize if this question is too noob for you guys, but I’m running out of ideas.
Thanks all for your help.

Vladimir

Of course you need some free memory, but not hundreds of MBs of it. I notice that you pointed the same XDA quote that is used and linked to by lots of different sites when this is being discussed. To use someone else's quote - better written than I could do so myself;-
In the most simplistic terms, here is how it works, and why "free RAM is wasted RAM," but also, why you don't want all RAM in use at any given time.
If an application is not in memory when you try to open it, that application haa to be loaded into memory, thus triggering a "load time." Having the application in memory (prefetched) prevents this load time and has the application load near insantly. This is why a modern OS will preload our most commonly used applications into memory. The more memory that you have, the more applications that can be preloaded, the smoother your device will run. Clearing this memory gives you no immeidate benefit, and will actually slow your device. Idle applications in memory consume almost no resources (CPU cycles, battery power, etc.). If an application is consuming resources, that means that it is doing something. Closing it will only force the application to re-load. Using a task killer for this purpose will cause a "boxing match" where the task killer closes the application, the app reopens itself, and back and forth. THIS will consume resources.
However, you want to have some memory free. Your devices will not have enough memory to preload EVERY application, so it has to guess based on your actions. It needs to have enough memory available to quickly load an app that you may want.
Let's say that you want to load an application that requires 256MB of RAM, but you only have 128MB available. This means that the OS is going to try to clear 128MB of RAM to accomodate your app, and as your app loads, will try to clear another 128MB to return to its previous state. This clear/load/clear causes a longer load time and more slowdown than just loading an app not already in memory.
So, the ideal situation is to have most common apps in memory (pre-fetched), but enough memory available to handle 1-2 common apps that are not already pre-loaded. Touchwiz (Samsung) devices allow you to clear memory from the task manager. My S2 had about 870MB of user-available RAM, and if I trashed all apps, it would go as low as 300MB in use. This may look cool, but it is a complete waste of resources, and the OS is simply going to re-load those apps over the next 2-3 minutes anyway. And if you use a task killer to keep your device idling at 300MB of available RAM? This is simply going to slow down the device, harm the battery, and give you the same memory performance and availability that you would get with an HTC G1.

As the OP was stating that "I only have 150 - 200MB Free RAM" with the Stock ROM, that is definitely NOT what is causing a lag issue. If you have that much free memory (before Android goes caching stuff and not declaring it of course) then you are absolutely fine on any Android device there is.

Maybe your partitions aren't mounted.I took these lines from pimp my rom init.d script.Create another script but it has to come before the governor tweaks script.

For example, name this script "93Mount" and name the governor script "94Governor" so the mounting script will be executed before governor script.

For the People who want Stock Gallery on CM and hate Aosp Gallery like Iam, check facebook offical cyanogenmod. They send a link to their new gallery next. Its in beta stase, so its not avaible yet. But if its stable itll be in play store. Its like the stock gallery app. Very beauty

I'm not sure it's the right track or not, it does happen to me quite ago.
The problem is the SD (my case, luckily it's external). The system try to read files from card but it got error thus try again => laggy
I removed the card and it's alive. Try to check your internal sd. hope that help

App didn't help, I got the same error. Never mind, I give up Will use Trickstermod after every single reboot until finally find solution. Thanks @ottomanhero for all your help.
@GalaxyVolvoZ that app looks realy nice. Finally a good replacement for Stock Gallery.
@klbterminator I don't have any problems with SD, at least didn't so far
Thanks guys.

[MOD][Interactive Tunables] Excelsior Profile

Hello everyone, here I present to you a stunning profile - Excelsior - optimized for performance, less heat & stunning battery life.​
EXCELSIOR PROFILE​
Explanation & Features
Well, many of you might be using GovTuner mod or Xenon Tweaks, but you might still be expecting Stock Like Performance, so for such people here I bring to you Excelsior Profile - meticulously calculated values for the Interactive tunables. This is brought to public only after a lot of extensive testing by myself & -DM-, for the most part he did stunning battery tests & brought me proof of concept.
The main aim was to achieve stock like performance but with less heat - this was done by making use of the lower & mid-lower frequencies for most tasks without any noticeable lag, which also translates to better battery.
Results are attached below.
Now, obviously everyone might have different results according to the rom used. The above results are gained from RomAur 4.2.1 with Xposed & Greenify, and browsing, messaging, some video, few calls, 2 e-mail accounts always running with imap push, stock messaging and 3rd party messaging app also always running in background with LTE always on, on a E6853 - Z5 Premium.
Installation
Now, for people with init.d support, just copy the file under system/etc/init.d & give permissions 777.
And for those who don't have init.d, you can just add .sh extension to the file & run it with root & on boot with any script manager app.
For people who use Kernel Adiutor - Excelsior.json has been attached, you can just go to Kernel Adiutor > Profile > Import & apply it and select apply on boot.
Downloads
init.d script - https://drive.google.com/open?id=0BzzQ3ZoP3L62WEtoTzNDWWRzaEk
Kernel Auditor Profile - https://drive.google.com/open?id=0BzzQ3ZoP3L62VkFERzI4OXVtUE0
Credits
Me - obviously.
-DM- for extensive testing & results.​

Giving it a go now. Will report back with how it's been running after a few days Thanks
BTW, what theme are you using in the first 2 screenshots?

Those 2 are mine, status bar mod with flat style bar indicators module, the nav bar is from xstana but I moded one of the theme in the apk itself as I wanted more spacing in between icons...by doing that the touch highlights on the nav bar were off centered so I made a theme to remove those highlights on touch...
The theme apk that I made is here ---->View attachment tmp_7829-gray-dav-1306345171.apk
Now for the Excelsior mod, getting a smooth fast experience all around...great battery life, phone is cooler....the mod is use on RomAur with Zach's Kernel 2_4_7, no thermal mod added (I will test with some in future)
@Christian Fleming did an excellent job with this mod...

Over the last few days, I've had fairly identical results. Everything seem to run super smooth, too.

I had everything same with and without profile.

Could you not read the original post?? It's mentioned there - it depends on your usage, for my own self - I get 5 hrs & 45 mins of SOT cause of games. Try use Greenify - it helps.

i have greenify combined with xposed for better results and even without games i get low SOT

anyone knows why greenify wont ask me for root? Its donated version
fixed it by disabling xposed module for greenify and than reenable it

New Version for Nougat.
*Recalculated some values.
*Less overheating.
*Better Battery.
*Balanced usage of all frequencies, the usage of frequencies above 1.2 Ghz is reserved for only tedious tasks resulting to better battery life for little cores.
*Frequent throttling of bigger cores to 1.9 Ghz reduced translating to lesser heat.
Still in testing phase.

2.3GHZ Overclock in ZUI 2.5?

So in the Nougat ZUI2.5 I saw the cpu clock frequencies include a 2.3ghz for big cluster, and 1.7ghz for little cluster, also an option for "OC mode" in the setting
But no app can access it, I tried Kernel Adiutor and it always reset back to 2.15ghz, and when I turned on OC mode the actual cpu clock doesnt reach 2.3ghz, more like a governor change to performance with default clocks.
Is anyone currious about how to use the higher clocks?

Been meaning to respond for a while now, I'm very interested in seeing this too and I've observed the clocks setting back to 2.15ghz, tried messing with system files and was tempted to make a custom kernel modification but I'm just waiting for someone else to introduce something.. if that ever happens, if more performance can be squeezed out then it'd be awesome, even if it already runs flawless, I enjoy pushing it further. I've been compiling some UE4 demos and tests and testing them to see what the phone can handle, I'd like seeing what overclocks could do to those results.

actually I got oc running in almost every single rom for the z2 plus now, just extract the sh file in the attactment to /system/etc, set permission to rw-r--r-- and you are golden
also a modified thermal engine file is included to raise the thermal throttling threshhold, if you want also move it to /system/etc then set permisson
remember to backup the old files, although I noted that all roms use the same default files. If you want to disable overfreq you have to move the original files back to place, removing them wouldnt do anything

That's really cool and I wanna use it but is it compatible with the Z2 Pro? I mean they use the same processors.

Don't work for me.

Did for me on the z2 pro, instant 160K in antutu on 50% battery, quite happy with that

Any way to include audio gains (headphones) for the kernel?

I'd like pushing it a little further, especially the GPU, just not sure how to go about that for now..

unfotunately you need a custom kernel for that to work, as the files I uploaded are only to enable the prebuilt overclock that zuk included with the phone. On custom roms based on cm/aosp I got the gpu to 652mhz which is the same as the sd821 SoC, and it worked fine. Not much progress has been done to raise the cpu clock higher however

I get the feeling that Elemental X is never coming unless someone works with the source code, I see it's on the OP3 so I wonder how tough it'd be to port it over, would love to get the GPU in the Z2 Pro to 652 as well, I wanted to run this thing at the same frequencies as the 821 but wouldn't mind pushing the clocks further, I have the source for the OP3 EX kernel but this stuff is way out of my skill set..
I'm pretty sure I found where all the clocks and voltages are stored within the kernel, but like I said, I got no clue what to do.

Are you using root explorer or copying within the recovery?, if you're using twrp you need to go to the mount option and check the box for system, and if you're in the OS you gotta use something like root browser.

I get the feeling that Elemental X is never coming unless someone works with the source code, I see it's on the OP3 so I wonder how tough it'd be to port it over, would love to get the GPU in the Z2 Pro to 652 as well, I wanted to run this thing at the same frequencies as the 821 but wouldn't mind pushing the clocks further, I have the source for the OP3 EX kernel but this stuff is way out of my skill set..
I'm pretty sure I found where all the clocks and voltages are stored within the kernel, but like I said, I got no clue what to do.

It doesnt have to be elementalx, although if any custom kernel get to that level of polish would certainly be welcome for this device. If you want to try overclocking via custom kernel, reference other devices that have the same SoC (sd820 in this case) to check what voltages and clock speeds they are using, and how do they implement the overclock (it could be very different between devices across many oems). I tried to follow xiaomi mi5's oc and didnt success, maybe you could do it better. Good luck!

Very interesting, got 155k in Antutu with it

"just extract the sh file in the attactment to /system/etc, set permission to rw-r--r-- and you are golden"
i changed the file in the system / etc folder but i don't know how to change the permissions from this file can somebody help?

I use ES Explorer pro, just long press the file/properties and check all boxes, you will see rwx-rwx-rwx

Between 3 and 5h, one day is no problem.

thank you i changed the settings to rw- r-- r-- and did a reboot after that. In antutu i only get a score of 13800 and if i run the app kernel adiutor i see the big cpu i set to 2150 MHz i also see the settings for changing to 2304 MHz but it doesn't change if i try to set it. Im on 2.5. 335ST with root. Before i changed the file my cpu was set at only 1708 MHz and i couldn't changed it to 2150.

You need rwx-rwx-rwx

actually I got oc running in almost every single rom for the z2 plus now, just extract the sh file in the attactment to /system/etc, set permission to rw-r--r-- and you are golden
also a modified thermal engine file is included to raise the thermal throttling threshhold, if you want also move it to /system/etc then set permisson
remember to backup the old files, although I noted that all roms use the same default files. If you want to disable overfreq you have to move the original files back to place, removing them wouldnt do anything

Thanks man it works perfectly. I'm getting 154K on antutu

Hi,
I did this but every reboot I need to run the script with root explorer. I tried rw-r--r-- and rwx-rwx-rwx.
