How to find optimal SetCPU settings

I am using cm 6.1 nightly and would like to know how to tune my mobile for long battery life. Wish setcpu could look into my usage and suggest presets for long battery life or performance.

my main is: Min: 245, Max: 710
Screen off: Min: 245, Max: 352
even without the screen off profiles or anything i still get 1-2 days + depending on my usage, and since i like to play with my phone and abuse the wifi/3g it lasts like a day anyway.

With screen on, max 633, min 480. create a profile so when screen is off, max 352 & min 160.
Mine is atm at 10% battery and it's been on for 51h & 30m and in that time it's been awake for 9h & 38m.
When i'm home, wifi is always on.
Gps is only on when needed, and so is bluetooth.

A suggestion for setcpu, it can collect the settings from users and provide the average as an option. This will really help new users. Integration with cm parts will be kickass.

i like yours max and min settings, but what type of scalling u guys use?
ondemand
userspace
performance
interactive (how does it work? couldnt find it on setcpu site)
thanks!

kept "ondemand".

By having different profiles, we end up changing the CPU frequency limits frequently. Could this harm the CPU? This question was asked elsewhere but am not able to track it (iirc, it was not answered)

I think it will harm CPU. i have been using few profiles for a week. Yesterday it froze for 6 times. . So yeah....

No it does not harm the cpu.
think of other cpu's like intel or amd, they also can be throttled either through the hardware or software, to lower power consumption when not used, and visa versa.

I just use the main profile, the phone tends to freeze when switching profiles so i removed all the ones i had.
Running 160-672mhz. Running fine and doesn't freeze anymore.

When i use a profile for screen off, it sometimes takes a second or two to switch cpu speeds. It's kind of annoying as if i don't wait for it to change to the main speed, it may freeze.
Anyone else experiencing this ?

SetVsel And Cyanogenmod 7 RC0

hello everyone
i have a quick question
is it true i shouldn't use setvsel with CM7?because i just read that in the FAQ thread for CM7 here:http://forum.xda-developers.com/showthread.php?t=1065798
and i need setvsel because i use it to undervolting and also i don't to overclock my cpu to 1Ghz since 800mhz can handle all the games i play and im getting 1900-2100 score in quadrant on stock cpu speed
and if i can't use it or shouldn't what program should i use ??since cpu settings in cm settings doesn't include undervolting
(although i've been use it on CM7 rom for 3 days now and i didn't have any trouble)
thanx in advance
appreciate your help guys

Hi there,
CM7 RC0 has the CPU clock speeds & Vsel in the bootmenu where you can overclock, undervolt, change the governor etc.
If you reboot your phone & go into the bootmenu when the blue led comes on then you can access the overclock menu.
There's more info in Quarx's thread in the dev forum

From what I've read in the relevant threads about CM7 many people are saying not use it.
I used it in froyo but since flashing CM7 RC0 I only use the bootmenu for CPU settings.

I used the same settings that peetr_ used in the post I've linked to above. It uses the smartass governor.
It appears that there's different settings depending upon which governor is selected:
eg; for the smartass governor then in the overclock settings list the settings that start with _smt are relevant,
interactive governor _int,
ondemand governor _ond, etc.
Think that's how it works

No problem pleased I could help
I left the bootmenu cpu frequencies as to what they were but undervolted them slightly.
300/22, 600/34, 1000/54 - I tried many settings using setvsel when running froyo so I know these work fine for me.
As for the other settings I just used those that peetr_ posted for the smartass governor & it seems to run nicely. Haven't had any issues yet

btw...when i used the values in the post you gave me the phone was running without any issues but if you open setvsel and looked at the cpu it keeps changing from 300 to 1000 even if you are not doing anything but if you used the ondemand scale governor you will notice that if you are not doing anything the value stays 300mhz so im not sure that smartass is a good governor after all...or maybe its just me
anyways i think i will keep the settings like this:
[email protected]
[email protected]
[email protected]
also change the other values in menu like this(i think you must change them according to the values you gave your cpu in the 3 vsels):
smt_min:30
smt_max:80(although i suspect this one should be 100 but since the user in the thread you gave kept it 80 im keeping it 80 )
smt_awake:300000
smt_sleep_max:300000
smt_up_min:1000000
smt__wakeup:1000000
smt_ramp:300000
ond_up_threshold:75
what do you think of these values ?
and also...can you tell my your temp in normal state and in after heavy use ?i think mine stays hot

oh and btw could you provide me with a link for the youtube apk you are using i can't seem to find a one that works

My cpu sometimes jumped from 300-1000 when I used setvsel on froyo.
Temperature wise it seems to be running similar if not slightly cooler than when on froyo. Now the hottest I have seen battery temp is 35C but it is mostly much cooler than that.

hmm..mine reached 39c on very heavy use...normaly its around 30c
and about the youtube app..no it wasn't included and i downloaded the app in the market but it crashes on most videos

btw im getting 2000-2500 in quadrant...how come?i think that is too good to be true

Here's what i've come up with, using google (lets correct them, if some are wrong) :
con_up_threshold: [80] # system load in % above which increases the CPU frequency?
con_down_threshold: [20] # system load in % above which drops the CPU frequency?
con_freq_step: [5] # frequency step?
con_sampling_rate: [160000] # interval (in milliseconds) between polls of the system. In fact, the intervals between changes of CPU frequency? Times in 160 seconds?
int_min_sampling_rate: [50000] # minimal interval (in milliseconds) between polls of the system. In fact, the intervals between changes of CPU frequency? Every 50 seconds?
ond_up_threshold: [86] # CPU in % above which increases the frequency of the processor.
ond_sampling_rate: [50000] # second? interval (in milliseconds) between polls of the system. In fact, the intervals between changes of CPU frequency? Every 50 seconds?
smt_min_cpu_load: [40] # CPU usage in % in achieving a reduced frequency of the processor
smt_max_cpu_load: [85] # CPU in % above which increases the CPU frequency
smt_awake_min_freq: [30000] # The minimum frequency of waking up?
smt_sleep_max_freq: [30000] # CPU frequency during sleep?
smt_up_min_freq: [1200000] # The minimal jump. so default made the cpu jump every time to max speed
smt_wakeup_freq: [1200000] # The frequency of waking up. It is important to not lose calls.
smt_ramp_up_step: [250000] # How much to increase the frequency at one time?

So witch is the best governor and settings for normal daily usage like some texts, calls, 3g/wifi, maybe some games ?
I'm on smartass right now with these settings
Vsel1 - 20
2 - 31
3 - 54
smt_min... - 30
smt_max... - 80
smt_awake_min... - 300000

i don't know...really..i can't seem to relate what are the values for with the available governors
my only problem with smartass governor that even if im not using the cpu the values keep changing between 300mhz-1000ghz but when im using on demand if im not doing anything with the phone the cpu stays at 300mhz but when i start using the phone(moving the screen up and down for example)the values changes to 1000ghz and when i stop the values goes back to 300mhz that's why im using on demand...but again it might be just my cpu
looks like it requires to dig more in the differences between each governor
anyway i read in the latest post in CM7 DEV thread that some people is actually using setvsel so i opened my boot menu,and went to overclock,selected set default,reboted,and installed setvsel and applied these values:
20/300
33/600
47/800
up_therhold:75
oh and btw...how's your battery life ?

Dudes, so please, quick answer:
Use SetVsel - no
use build in "overclock" settings in CM7 RC0 - yes?
Any one using CM7 RC0 bootmenu> Overclocking?
There are more values than in peters thread.
Please advise with all info/numbers according to present in overclocking bootmenu 0.8.6 values.

Yes I've got CM7 RC0 & using the bootmenu overclock.
There's many values in the menu as it depends upon which governor you have set it to so only those values relevant to that governor will be used.
For instance on Smartass governor - the values starting with _smt will apply

[DISCUSSION THREAD] Fluxi XX Kernel ICS, Non-development/settings/battery life etc

OK as Fluxi XX kernel is becoming more and more popular it seems a perfect time to split the chit chat going on in the Development thread.
Please use this thread for all your non-development chat and sharing settings, battery life screenshots etc. If you're unsure about where to post your questions then please post them here and you'll get lots of other users who are willing to help you.
The original German forum for myfluxi can be found here: http://www.android-hilfe.de/kernel-fuer-samsung-galaxy-s2/236546-aosp-aokp-kernel-04-05-12-fluxi-xx-kernel-ics-xxtweaker-app-xxtouch-recovery.html
The new development thread is here: [AOSP/AOKP-KERNEL] Fluxi XX Kernel ICS [wakelock and drain-free slide2wake for SGS2]
Downloads for latest version:
Kernel CWM download: fluxi-kernel-sgs2-XX.03_s2w_b3.zip
xxTweaker apk download: fluxi-xxTweaker-0.4.0_beta1.apk
Slide to wake is currently beta and enabled by default but to disable it do the following in ADB, terminal emulator or a script (if you can get it working):
echo "0" > /sys/devices/virtual/sec/sec_touchscreen/tsp_slide2wake
If you're going to post bugs please do not just post "My phone is slow", "xxTweaker is not working". Remember if you have issues you need to help myfluxi/others help you so post logs to help diagnose your issue. Here's how to get the logs using xxTweaker:
1) Open xxTweaker
2) Scroll down to xxTweaker option (last in list)
3) Scroll down to "DEBUG AND REPAIR" section
4) Select "Debug system logfiles"
5) This will place a file in /sdcard/xxTweaker/logs
6) Attach this file to your post detailing exactly what's happened

Remember to post as much detail as you can along with your attached logs describing the issue you have and if possible how to reproduce it something along the lines of:
Issue experienced: e.g. SOD, freeze, lockscreen unresponsive, slow mo bug etc
What were you doing: Brief explanation of what you were doing when it happened (not applicable to SOD)
Your setup: Are you running stock settings, overclock/underclock/undervolting, governor/scheduler etc
Can it be reproduced: Is it consistent or was it a one-off and if it can how?
If you're new to the kernel then this is the best place to ask any of your Fluxi related questions.
If you have any ideas about how to improve this thread then please post your ideas or if you have any useful how-to's etc related to using the kernel/xxTweaker app then also post these and I can quote your posts in the 2nd post.
Thanks for helping keep the development thread on topic.

FAQ
Q: Wakelocks "wlan_rx_wake" wake up my device constantly what I can do about it?
A: The problem is neither Android nor the kernel, but the router and the (Windows7) network. In the network properties, uncheck "IPv6", disable the service "IP Helper", "Shell Hardware Detection" and "Windows Media Player Network Sharing Service", which provide ongoing Traffic. Then they scored again 98% of deep sleep.
Q: I have setted below maximum Suspend 500 MHz, 800 MHz is also used as the step. Why is this so?
A: "The device" wakes ALWAYS at 800MHz and goes to sleep as well, regardless of which settings are made. The hardware selected 800Mhz to ensure stable operation - change by software impossible.
Q: I need the "intermediate steps", ex. 300 or 700MHz, the CPU frequency table is not. Can I change this?
A: In theory: Nope! In practice: The option of individual frequency steps is a nice gimmick but virtually unnecessary as intelligent as governor select ondemand, conservative, or the interactive dynamic frequency target. The driver provides the steps of the governor decides. Future versions of the SoC Exynos therefore also use 100MHz steps.
Q: The xxTweaker remembers any settings, what is going on?
A: If only some Tweaker settings are not applied, I made a mistake (because I forgot to add them). If no settings are applied, there is something wrong with the permissions. Either missing from the root and the tweaker or directory /data/data/net.fluxi.xxTweaker/shared_prefs chmod'ed is wrong. The latter does the installer script at startup, if you like, it can also manually delete them.
Q: When is the superuser request every action, you can turn that off?
A: Simply update the su binary file: app drawer/superuser/Preferences/ "Press to check for updates" / Important "update anyway" / "Allow"
Q: I can not download, I just get a file "download.php".
A: The Android browser does not understand the PHP script on the server. Either 1 Rename the file and provided with the correct extension, eg "download.zip" or try another browser (Opera, Chrome) or use the PC.
Q: When the device wakes up from sleep or change the lighting conditions, the display is usually too bright / dark. It then takes a few long seconds to realize it, how bright it really is and then it adjusts the brightness. Is there a fix?
A: Yes and no. First, this is completely independent of the kernel. Basically, this is a source CM9/Open Source/Samsung-****ing-and-hold-consorts-important-things-to-lock problem. The HAL is the light sensor from Samsung is not documented and can not read CM reasonable values​​. Use the open-source sensor HAL (xxTweaker | System | Exynos sensor HAL) and the CM settings for automatic brightness (CM | System Settings | Display | Automatic Brightness | Step Customize | Editing levels). However, there is the possibility that thereafter the compass haywire.
Q: Help, BLN works in applications X and Y but not Z!
A: The poor kernel is innocent. BLN is as follows: The Android app generates a notification event, it triggers the liblight module, which writes to the sysfs kernel, liblight kernel module and have to rely on the information from the user space, so the ROM. In other words, from the perspective of the kernel, either always or not working.

Keep in mind that wifi also consumes some battery I wouldn't let my phone on while i'm sleeping. At least I would kill the open apps and turn off wifi.

Well SlimICS is CM9 with cherry picked bits of AOKP. Saying that though. I still got better battery life with the proper CM9

Personally I think ROM choice has less to do with it and the apps you've got and accounts sync'd etc are where you will save battery. If you freeze/remove anything you don't use then you'll do better and obviously using UC/UV etc will help a tiny bit too. I personally leave everything stock clock and voltage wise and just use my phone as I see fit. Remember the less you monitor and worry about the battery the better it will be Battery life should never choose your ROM, whether or not it's useful to you and what you like should

It's never best practice to judge battery life on the first cycle, just use it, drain it, charge it, then after a few days try monitoring your battery to see what it's doing, but if it's lasting you a day then shouldn't be a problem, or have I just not got as high expectations as everyone else?

Well SlimICS is CM9 with cherry picked bits of AOKP. Saying that though. I still got better battery life with the proper CM9

Slight correction it's not CM9 it's AOSP from Google sources with cherry picks from CM9 and AOKP

There's only two types of ROMs: Samsung Stock and CM9. Every other ROM is a modified ROM from those two. Well, there's b2g also, but no one uses it.

I find it strange that the battery life I get on CM9, i have never achieved on any other ROM.
SlimICS
Several AOKP Rom's
When I've used the Roms I've always used Fluxi and the same kernel settings, plus, given it chance to settle too.
CM9 for some reason seems to consume less battery when the screen is on!

Bro, I've freezed about a total of 18 system apps from slim, extreme UV, UC 100 ~ 800, tweaked governor settings, gpu max step is 160, gpu UV more extreme than superleeds, only absolutely necessary apps, only inverted apps, and full black settings, no fancy color themes, autostart disabled of some services, sync only required apps and tons of other cherry picked tweaks, and i never get past 13 hours, and with screen of 2 hours. Anymore tweaks, and i rather sell off my S2 and get a nokia 3310..
The only thing i may be off the battery saving method is i'm using floating image live wallpaper, as i like to see my wife and daughters photo on my screen.. And even made sure that floating image does not misbehave, process usage and wakelock by FI, is very minimal.
My aim, is to have a minimal of 20 hours with screen usage of 4 hours.:fingers-crossed::fingers-crossed:
This is due to me sometimes being on the road and especially when i'm out on the boat fishing (hobby) for a few days...
I have no qualms when i'm in office or at home, i'm in front of my laptop almost 90% of my wake time.

Welcome to the Unofficial Boeffla Kernel App Profile Sharing Thread​
Introduction
This idea was tossed around in the Boeffla Sammy Kernel thread so I decided to make one here in the General Section so that questions regarding user profiles would not clutter up the main thread.
If you want to share a profile, just upload it to your host site so that other users can grab it
For those that want to implement other user profiles to their device, simply grab the .bcprofile profile and place it in the boeffla-kernel-data directory in your internal storage and then open the Boeffla Config app and load the profile in the upper right corner of the screen.
oh, and one last thing..please remember that the Galaxy S3 is a diva and will not behave in the same manner for everybody..we all have our own unique usage patterns, so dont expect that one profile will be as effective on one device as the other..you may always tweak a profile once you download it so that it will fit your preference
=============================================================================================================================================
Read posts #2 and #6 for explanations on some configurations and settings.
All shared profiles are listed at post #3 while activation procedure is at post #4
For kernel updates and download head over to Official Boeffla-Kernel website.
For discussions regarding development, and we mean DEVLOPMENT ONLY, head over to the Boeffla Sammy Kernel thread, and Boeffla CM11.0/Omni/CM10.x thread.
All credits goes to @Lord Boeffla for an amazing kernel. :good:
**Fan teaser created by mateepunkt !**
​
First things first:
For those asking what config is best for which rom, THERE ARE NONE. All configs shared here are cross compatible with all roms. Ok, not all, since they are bracketed into Touchwiz and AOSP configs, but you get the idea. For all first timers, please try out Archi's and Lord Boeffla's and metalgearhathaway's configs first. I've been saying that for quite some time now. You can also use those profiles as basis for your own, which you can in turn share with everyone else.
​
For a comprehensive guide on all things that can be tweaked in a kernel, please read up on the following write-up by @gsstudios :
Some of the governors and schedulers and other kernel features are not implemented by @Lord Boeffla on his kernel, so just read up on those that are included in the Boeffla Kernel.

A few things explained:
PIRATA! said:
Thank you for your reply, and I have to say that I have to ask you a couple of things because you know the poor situation I'm in.
First of all, what does it happen if I uninstall the samsung push service? What I will not have any more?
What happens if I greenify to hibernate google play services as you say? Same question as above... Does it still receive Play Store automatic updates?
My connection is not the most perfect of ever as I continually switch between 3G and 2G due to my provider. Can't do anything about that. In such a way, I can say that I always have signal, wherever I go. Then, I have to say that I use a lot my device for internet, and in 2G it's toooo slow for use, I tried, especially because my provider is an H3G provider that users 3G a lot. Here in Italy using 2G connections it's some kind of bad for internet. Some provider do, bit Theo are quite slower. Maybe battery drawning for this it's the price to pay. I'll anyway put an eye to the app you say and see what it does, tnx!
My screen is always at minimum bright, and often use ScreenFilter to 40%, so I would not consider that too much, no?
About lockscreen effect - water droplet and all the sounds, well the water drop sound is off, and about the other like key pad it's also off. But I have to say that I keep my phone quite constantly in vibration mode, so dunno if sounds events are called anyway if active.
The only one it's active it's touch keys vibration because I like to feel that!
The water drop at lock screen is there, and the reason is that I have a Samsung phone and I like that unlock method. You say that it drains a lot of battery?? I should really change that?
Maybe I should first of all put my hands on the processes that run in background and in the kernel settings.
I am with PegasusQ battery, row with 512 on internal sdcard, cfq with 1024 on extsdcard, AFTR-LPA Aggressive, no cpu OC/UC, no cpu UV, some gpu freqs lowered at low steps, but still the same at high steps so to have stock freqs in games, some general gpu UV, screen touch boost at 600, Boeffla sound with all active minus the Mono output, Frandom tweaks, 4 zRam at 200 with 80%, stock LMK, no logging.
Hope to have said all.
Should I look at you second post I quoted down here for the file you linked and freeze/uninstall most off the apps listed there, and then greenify most of the remaining, keeping an eye on the system ones like you did??

1/ samsung push: nothing happens if you dont use any samsung apps like chatOn. opne play store and search for samsung push service -> read the description and you will see -> reduce a lot of wakelocks according to your BBS
2/ Greenify play store: you may lose autoupdate but they will be triggered again when play service is activated -> you dont lose any update but it is slower than normal. I recommend you to turn off autoupdate in playstore settings and update apps manually. Autoupdate is reported to consume Ram and battery -> this will reduce a lot of wakelocks (A LOT)
google play service was updated to v4.1 and claimed to save a lot of battery. I dont care, I turned it off
3/ Only use 3G when you need to surf the web. Use 2G when you put your phone in the pocket or only when you use IM chat apps like viber and whatsapp. Im fine with these
also try intelli3G. I have never used it but I think it helps
4/ using lowest brightness is very good. Use autobrightness at the lowest level in outdoor conditions
5/ DONT USE PegasusQ with AFTR+LPA -> your phone cant reach deepsleep state
If Im not mistaken, I read this from somewhere that if you use AFTR+LPA, your phone can only go to deepsleep only when there is 1 core running. If there are 2 cores running, it prevents your phone to go to deepsleep
usually, pegasusQ keeps 2 cores running and maybe switches off 1 core after a period of time (I dont know when) -> goes against AFTR+LPA
pegasusQ battery saving & pegasusQplus battery (maybe there are some more but I dont remember) are the only governors that switch off the 2nd core quite fast so if you use these, it's fine but in general, I dont recommend to use pegasus with AFTR+LPA
I use zzmoove yank battery extreme instead. If I wanna play games, I use pegasusQ battery
with exactly the same configurations, PegasusQ battery seems to be slower and makes my phone hotter than zzmoove yank battery (dont know why). It got 44*C, never happens with zzmoove. Both are set at 1.2ghz, same GPU, same UV
I monitored the behaviours of these. However, because the overheat, I cannot go with pegasusQ battery
6/ turn off all sounds and effects and see how it goes. In the older versions of touchwiz, they are reported as the culprit of using too much ram and causes too many wakelocks. I dont know sammy do fix this or not because I always turn them off from the beginning
I dont recommend using CFQ with extSdCard because according to a credible source - thanks droidphile:
it might causes problems with mediascanner. I prefer SIO and ZEN. In fact, changing these in the extsdcard doesnt bring noticeable difference, quite minor in my experience because we dont always use sdcard and the speed of this is limited. You may see noticeable improvement with internal storage
7/ you should consider the list of frozen apps. you will have more free ram because useless apps are removed. They wont consume ram and battery and cause wakelocks.
if you have a look at my screenshots, you can see, AndroidOS only took 4% -> I was surprised also, couldnt believe that. I only have ~2 minutes of wakelock in 11 hours of deepsleep. I use facebook + fb messenger + viber, they cause wakelocks. I dont greenify them
I dont dont know. there should be soneone who has time and do a lot of benchmark tests to conclude. IMO row is very very fast but writting speed is slower than the others (read over write) and battery might be a bit worse. ZEN I have no idea but it is fast and works well. Andi said it saves some battery so I use ZEN. I dont have time to test. negligible difference because s3 is a flagship. It is easier to conclude in a cheap phone
try zzmoove. Pegasusq battery mostly uses 1 core so it would cause some delay. check your battery, maybe it gets bigger => not good => considered to be replaced. If it is bigger, input current is not enough to keep phone working (quite similar to undervolt) => stucked
moreover, maybe your free ram is too low that makes it slow. increase empty app to 110 or 128. change content provider to 100

Why can't you activate a downloaded profile?:
Lord Boeffla said:
Guys, this is always the same: If this message comes up, the file which should be imported does not have the correct format.
This can happen when a download is incomplete, when browsers think they need to modify the file in any way, when there is any other corruption etc etc.
In order to check if a file looks alright, open it on a PC and check if it has:
- At the start of the file the sequence {"data":{
- At the end of the file the sequence }}
- There must be no line breaks at all in the file
It is nothing else than a JSON file, so you can open it in any text editor to see what is in.

More Things Explained:
ASV Level Explained:
Lord Boeffla said:
Samsung bins their chips according the ASV level, which can be thought of as the "quality" of the chip. The higher the ASV number, the better the chip, and the less power it needs to do its job. At the factory they mix increased gate voltages with varying body voltages to end up with a table of stock body biases. Long story short, this is how they deal with less-than-perfect chips. It's a lottery for the buyer. But since their values aren't tailored to your chip - the hope is that maybe you can scrape by with a bit less power than Samsung thought a chip of that grade could.
So in short: It tells you about which voltages will be used by your Exynos processor. Good ones can run with lower voltages, worse ones need higher voltages.
The asv level is used to look up the voltage table during bootup and initialisation phase.

Low Memory Killer Explained:
Papa Smurf151 said:
Explanation of LMK Settings (Low Memory Killer)
and
Explanation of Adj and Minfree settings
When your phone boots up, a file inside the boot image (init.rc) sets the system parameters. Things like the path to framework files, setting up your networks, and setting the limits at which programs are killed off to free RAM are done by this file. Now a super-Android-geek might dig inside the init.rc file and completely customize the low memory killer, but you don't have to do this to still get good results. The init.rc sets up six different "levels" of open applications. Let's have a look at them:
FOREGROUND_APP: This is the application currently on the screen, and running
VISIBLE_APP: This is an application that is open, and running in the background because it's still doing something
SECONDARY_SERVER: This is a process (a service that an application needs) that is alive and ready in case it's needed to do something
HIDDEN_APP: This again is a process, that sits idle (but still alive) in case it's needed by an app that's alive and running
For the most part, we never want to adjust when these apps and processes are killed off. They are the things that the programs we use need to properly function. For the more bold and advanced users, changing settings for HIDDEN_APP settings is possible, albeit with a LOT of trial and error. There's two more settings, and these are the ones most interesting to us today:
CONTENT_PROVIDER: This is apps that provide data (content) to the system. HTC Facebook Sync? That's a CONTENT_PROVIDER. So are things like the Android Market, or Fring. If they are alive, they can refresh and provide the content they are supposed to at the set interval. If you kill them, they can't of course.
EMPTY_APP: I call these "ghosts." They are apps that you have opened, but are done with them. Android uses a unique style of handling memory management. When an activity is ended, instead of killing it off Android keeps the application in memory so that opening them again is a faster process. Theses "ghost" apps use no battery or CPU time, they just fill RAM that would be otherwise empty. When this memory is needed by a different application or process, the RAM is flushed and made available for the new app. To satisfy the geekier people (like myself) Android does this by keeping a list of recently used apps, with the oldest apps in the list given the lowest priority -- they are killed first if RAM is needed elsewhere. This is a perfect way to handle 'ghost' processes, so there's no need to touch this part
So when you see settings like this 8,14,40,50,60, 75 you start with the first setting and it looks like this
FOREGROUND_APP = 8
VISIBLE_APP = 14
SECONDARY_SERVER = 40
HIDDEN_APP = 50
CONTENT_PROVIDER = 60
EMPTY_APP = 75
You can manipulate these numbers so that they are better managed and give You different aggressiveness and a faster UI
For the Smurfed Out script the settings are as follows
Lite = 8,14,55,70,85,100
Medium = 8,14,75,90,95,125
Max = 25,35,55,70,150,250
Extreme = 25,35,75,90,150,250
Minfrees are set as well but they are equal to the LowMemoryKiller ADJ settings.
I personally run them at Max while using ICS but everyone's experiences will be different.

ZRam Explained:
-CALIBAN666- said:
Once a brief statement for those who are not traveling so long in the Android scene:
ZRAM = ramzswap = Compcache
In order to explain more precisely ZRAM first need other terms are more clearly defined:
Swap can be compared with the swap file on Windows. If the memory (RAM) to complete the PC the data that are being used not actively outsource (eg background applications) so as to re-evacuate RAM free. To this data is written to a hard disk. If required, this data is then read back from there easily. Even the fastest SSD is slower than the RAM. On Android, there is no swap!
In ZRAM unnecessary storage resources are compressed and then moved to a reserved area in the fixed RAM (ZRAM). So a kind of swap in memory.
This Ram is more free because the data then only about 1/4 of the former storage requirements have. However, the CPU has to work in more because they compress the data has (or unpack again when they are needed). The advantage clearly lies in the speed. Since the swap partition in RAM is much faster than this is a swap partition on a hard drive.
In itself a great thing. But Android does not have a swap partition, and therefore brings Android ZRAM under no performance gain as would be the case with a normal PC.
In normal PC would look like this:
Swap = swap file (on disk) -> Slow
ZRAM (swap in RAM) -> Faster than swap
RAM -> Quick
With Android, there is no swap partition, and therefore brings ZRAM also no performance boost.
The only thing that brings ZRAM is "more" RAM. Compressed by the "enlarged" so to speak of the available memory. That's on devices with little RAM (<256MB) also pretty useful. The S2 has 1GB but the rich, and more than. There must not be artificially pushed up to 1.5 GB.
After you activate the ZRAM also has 2 disadvantages. The encoding and decoding using CPU time, which in turn has higher power consumption.
Roughly one can say (For devices with more than 512MB RAM):
Without ZRAM: + CPU Performance | + Battery | RAM
With ZRAM: CPU Performance |-Battery | + RAM
For devices with too little RAM so it makes perfect sense. But who shoots the S2 already be fully complete RAM and then still need more?
Check whether you can ZRAM runs in the terminal with
free or cat / proc / meminfo
I hope it helps to understand zRam!!!!

A Few Things To Remember:
-When playing around with CPU/GPU profiles, remember to reset the values first before applying another profiles. This sometimes causes the profiles to not be set properly. You can do so by pressing the reset button beside the profile selection drop down box.
-Also, when playing around with the voltage table, remember to also reset the values of the voltage table first. This is causes a lot of voltage tables to not be set properly because when you try to switch from a table to another, the table from the previous profile sticks. Keep in mind also that undervolting too much will cause not only lags but also random reboots. If you want to undervolt, do so step by step, dont just jump straight to -100 and expect the device to still be as stable as before. Keep in mind also that the chips in our S3's are different from one another, as stated in the ASV Level explanation above, so not all voltage tables in shared profiles will be as effective on all other devices.
-When adjusting LMK settings, you have to be aware of how you use your phone i.e. how much multitasking you do, games, music, etc. There is a big difference sometimes also in roms where there are an abundance of memory tweaks in the init.d folder or however the rom developer implements his memory tweaks. That also comes into play with regards to memory management. For example, in CM11, I always have above 300+mb free of RAM when idle, while only having 200+/- mb free when running Sammy based.
-ZRam is not for everybody. There are users who report that ZRam sometimes causes freezes and lag [including me], and has been widely a cause for much discussion. As Lord Boeffla has always said, if you're not a heavy multitasker, dont use it.
-It is not advisable to use a Sammy kernel profile on CM or Omni, and vise versa. There is a reason why Lord Boeffla created spearate threads for his kernels, since there is a ton of difference in the code and configuration implementation between them. As stated by him, "If you are on CM or Omnirom kernel, reset your undervolting for CPU and GPU + reset your LMK settings as they might not apply for your S3 (my profile was taken from Samsung kernel !!!)".

The Great Undervolt Debate
Raphy511 said:
Hello,
I am not sure that undervolting can increase battery life. I even think it's the opposite effect
Demonstration :
Increasing battery battery life means using less power.
Power (P) is : P=U(voltage) x I (Intensity)
Most energy used by processors is converted in heating. It is like a resistance.
Voltage for a resistance is U = R x I. (ohm)
So Power used by the processor is P = U * I = R * I * I = R x I^2
So to reduce energy consumption, we have to reduce P. We cannot change R, so we should decrease Intensity.
Power used by processor cannot be change. So if we undervolt, intensity is increasing so the processors heats more and it is the opposite effect.
So why undervolt?

P is NOT CONSTANT.
R is semi-constant (semiconductors are weird, so can be nonlinear), gate capacitance C is constant.
If you lower V, you lower I, and thus, you lower P=V*I
That's the whole point of reducing V...
In general, UV is best for, on most devices, 3-5% reduction in CPU core power consumption before you hit stability limits. For general day-to-day use this results in less than a fraction of a percent of total system consumption being saved, but can matter if you're a heavy gamer, giving you more headroom before hitting thermal throttling and consuming less power.

I or current does not exist as a constant in transistors. Semiconductor physics are different from normal macro-electronics. The same principles still apply but they are meaningless as their magnitude are lowered to nothingness.
Main power dissipation and power consumption is caused by dynamic leakage on the transistor gate while it is switching. Secondary power consumer is static leakage caused between gate and the body.
The usual simplified formula for CMOS transistors is expressed as
Power = Voltage² x Frequency x Capacitance
or
P = V² x f x C
That's basically it in very simplified terms. And as ewdinpang said, lowering voltage has a squared power decrease in the dynamic leakage power. This has been measured and proven, from myself included.
The full expanded forumula is here:
This is a nonsensical argument, temperature aka heat, is power. If you are getting a less heated phone, then your battery life is improving. If this wouldn't be the case then you are holding the solution to the world's energy problems in your hands.

Alright, I am rather a noob. I've been seeing ''AKT this", "AKT that" around the threads, but just yesterday did I really discover what's up with that AKT... It took me a lot of searching as it wasn't quite apparent what to install and where to get it, the threads are a bit messy, hence this one. Correct .APK for Zuk Z2 Plus attached. (the link from the original thread: https://androidfilehost.com/?fid=745425885120764798, same file)
This tweak is applicable to every phone with any ROM or kernel--stock or custom--that provides the Interactive Governor.

ADVANCED KERNEL TWEAKS
Asiier said:
I'm about to tell you how to get buttery smooth, lag-free performance with insanely good battery life, using an old school governor featured in practically every kernel... This tweak is applicable to every phone with any ROM or kernel--stock or custom--that provides the Interactive Governor.
Yeah, yeah... everyone promises good battery with great performance, but who actually delivers? Maybe it isn't as smooth as you want, or maybe it requires something your kernel or ROM don't support. Or maybe the battery life promises just aren't what you expected. There's always some awful compromise. Not here!
This isn't a guide to get 36 hour battery life... provided you never use your phone. That's deep sleep optimization, which is lovely and all, but what good is the phone if you can never use it?! And with the new Marshmallow Doze feature, this strategy is becoming a thing of the past. What I'm talking about is 7-14 hour screen on, actual hands-on usage times! Without compromising anything, you can get 7-8 hour screen on usage with regular, no-compromise usage habits: daytime visible screen brightness, both radios on, sync on, network location on, all the regular usage features, the whole kit and kaboodle... all smooth as a baby's butt and snappy as a Slim Jim! (Up to 14+ hours if you can stand minimum brightness and WiFi-only with a custom ROM and other stuff turned off! And this is with stock voltages and full frequency range--you'll likely get even more if you choose to optimize those as well!)
However, it should be noted that this does not apply to gaming, heavy camera use, etc. Anything that is an automatic battery killer in and of itself. There's nothing that can be done about anything that forces the phone to utilize its maximum resources all the time. But you should know that by now. Further, this guide is about optimizing the CPU as much as possible. It does not cover things like eliminating wakelocks so your phone sleeps well, removing unnecessary and battery draining stock apps, keeping your screen brightness down*, and all that stuff that's been covered in other posts ad infinitum. Those optimizations are up to you.
If you really want to know the principles of this tweaks, please go to this thread since there everything is really well explained and I know you guys just want to apply the tweak and forget about everything behind it

this is really old news now, also AKT was designed around Nougat, and most ROMs now is Oreo. Helix Engine is a much more optimized version of this tweak, with profile changing upton every app so that you still have top notch performance and good battery on two separate apps

There is also a new app on the AKT thread that can be used on oreo to apply Oreo specific profiles instead of using ek kernel manager

It does not contain "Oreo" profiles per se, but allows for applying/saving/comparing profiles and loading/converting shell scripts. The Oreo AKT profiles are included in the post.
I'd be interested to know if and how well it works on your devices, since it's been made and tested on OP3/3T.

Pretty good actually , i have tested it out a lot across multiple roms
If the op wants , you have my permission to go through my post history, extract the relevant posts and put them on this thread , just mention me somewhere ?

Zhana seems to be the most used, but obviously try out others too if that does not meet your needs.
To me, the lag with Zhana is next to zero.

To me, Zhana Battery and X.A.N.A. Extreme are the best profiles for battery saving. When in moderate use, I use the Zhana profile on my ZUK Z2, which gives me 8h29min of screen usage (WhatsApp, YouTube, Netflix, watching anime online, using Mozilla Firefox and Spotify all day). When I want to play with performance focus I use the balanced profile Ghostpepper and I do not have lags or blocking playing PUBG Mobile, however the battery consumption is higher, which is normal. All this accessing the Wi-Fi. When I use 4g, I choose the X.A.N.A Extreme Battery profile, and yesterday, provided me as per the attached screenshot. Even using X.A.N.A. I have no lags at all when I play.

We'll be trying out Fair park today.
Quote: (There have been a lot of controversy about this tweak lately. So after you complain, this will NOT work for all of you guys.
For me, it works perfectly and it accomplished all that I'm going to state, but maybe you guys will experiment lags.
This tweak is not for everyone.
Probably the most battery efficient tweak ever created, fantastic battery with extremely smooth performance even playing games as Clash Royale or Pok?mon GO.
You can easily get 10 hours SOT or even more (If you don't play any games) just texting, browsing and so on could give you even 12 hours SOT.)

Nnmyeah, not happy with it, the CPU is awake for no reason. Moving on to XANA EXTREME.

Just to clear my doubt.
Install the apk, apply the profile on any phone (that supports interactive governer) and done.
Right?

I'm on AICP 12.1 (based on Nougat 7.1.2) with Magisk, and I'm on Project Zhana Battery, but I find no difference between normal usage and AKT. I'm still getting only 5-6 hours SOT.
Is there anything else I have to do?
Is AKT magisk module better than the APK?

Probably your kernel has touchboost enabled. I had to switch to Heliox (from 15.10 as recommend by other AKT users) to see any difference.

I am going back to Zhana, seems most stable. I'll stop messing with the phone for awhile and see how its gonna go.

Zhana always keep the phone under 40 degrees. With the others, I've seen even 55 = inefficient processing.

Yes sir. Any Snapdragon 820 phone, rather. And touchboost disabled. I had to switch to Heliox (from 15.10 as recommend by other AKT users) cause my original aex 4.4 kernel had touchboost @ 1000mhz for 1 second I guess.

Apparently, the module is basically the older version of the app before they managed to make it work as an app.

1. Is this app the way to get started with AKT or are there any pre-requisities?
(Downloaded app & scripts, clueless for the next steps ? )
2. Looking for latest profiles supported on oreo & step by step guide.
3. Also, does AKT is supported on Oreo?

AKT does support Oreo and although most profiles have been developed on Nougat, people report they work well on Oreo too. In the AKT thread you can find the FusionOBeta, which is now under development for Oreo (on OnePlus 3).
As far as prerequisites – you'll see everything in the post. My app does not have any profiles in itself. It allows loading profiles from files (scripts or "profile" files). In the post I have included a ZIP with all AKT profiles as script files. If you want to apply one, you can follow these steps:
1. Install the app and run it once (also allow root)
2. Unzip the AKT scripts and place them a sub-directory in the "Kernel Profiles" directory. They can be anywhere, but it's easier for you.
3. Open the app and use the "run script" feature. Then navigate and apply the script you want. Note: This may require you to have busybox installed, so I'd do that in advace. Also the AKT script do require a bit of time to apply, so be patient.
4. You can stop here, if you want, the profile is applied. If you restart, your device will be restored to stock settings. If you want you can do the following:
A: from the app settings, select the script you want, to apply on boot
or
B: keep reading
The app is generally made to work with "profile files", not scripts. So if you want better support, after you apply the script, you can save the current settings as a "profile" and apply that. That way the app will show the currently applied profile and allow for easier swap between two profiles.
Let me know, if I can be of further help.
