Do voltage changes take effect immediately? I can't tell if adjusting the slider actually does annything and I'm trying to test how low I can go.

When you hit apply the voltage will be saved right away. I'm using System tuner in the pas but now using Android tuner but same principle.
I don't see an apply button anywhere, I've just been clicking "Save" and overwriting my last save each time. Is there an app that shows what voltage it's currently running at, like it shows the frequency it's running?
Trickster Mod
Trickster does the same thing...slightly easier to use.
If you want the voltages to persist after a reboot in ST make sure you go to boot settings and enable CPU settings as an init.d script.

I am on gummy 191 and I just installed voltage control thinking running lower voltages might noticeably improve battery life. I can't figure out how to run the app. It doesn't install an app drawer icon and I don't see it in the settings screens either.
How do you start up the app??

try uninstalling and reinstalling it from the market if itll show up in the app drawer
It should be in your app drawer, a little lightning bolt or something. Once you start it grant superuser permissions, then it shows sliders for minimum and maximum voltage plus the voltage your phone is idling at currently. Put those at whatever you want (default should be min. 100 and max. 1000), then the advanced tab will give you more sliders to adjust individual voltage steps. Adjust them and use for a day or two, then adjust some more and just keep tweaking till you find the right combo of stability, power, and battery life

Hi all,
I've got a problem with System Tuner. On every ICS ROM I try the CPU clock and voltage settings won't stick. After I reboot the phone they go back to their defaults. Hence, I've got 3 questions:
1. Does everyone have these problems? Did I not check a setting or something?
2. What alternatives to System Tuner don't turn the second CPU core permanetly on?
And 3. Is there an init.d script which lets you set the clock speeds/voltage settings? Because I would rather not use an app at all to do that.
Set your CPU clock and voltages, then press Boot settings on the cpu tab( small button ), press Re-apply CPU Settings -> On boot completed.

Yes I did that, but the minimum frequency doesn't stick.
Nobody?
I'm using No-frills atm, but does that turn CPU1 permanently on?

My setup is similar to yours except I'm on ARHD 6.5.3.
I can confirm it is changing back to 192Mhz min. Could be kernel related as I'm on bricked 3.0 v5 too. Maybe we should ask showp-1984 or it cold be related to System Tuner.
Did you have tried another software like setCPU?

Hi there I'm on same Rom but with serbas ken and I use system tuner pro and mine sticks even after reboot, on a off chance do you have oc demon disabled in boot settings

Could you be more detailed Do you mean " Re-Apply CPU settings" if so yes I had it enabled. I will reflash stock o any other kernel and check if it's going to solve this.
I also have this problem with system tuner pro, now i'm using setcpu and the settings stick.
using vipers 1.1.0, tried anthrax/bricked/faux123 all didn't stick.
You know you.could ask the dev of super tuner. He's always very responsive anytime I've had issues. Also having different versions backed up in Ti helps as well cause a new update fixes one thing from a slew of phones but might just break yours. Having a backup versions means you can go back restore and test.

In relation to your second question, what kernel are you using? Faux's kernel has the second core on by default. System tuner doesn't have the ability to turn it off. If you want it offline until it's needed, try seb's or bricked kernels instead.
System Tuner 3.0
Just to let you know System Tuner 3.0 was released some time ago and provides improved CPU handling, new GPU, Gamma, MP, thermal controls on many custom kernels and a lot of other new or improved features (entropy, fstrim to name a few).
This is now a spawn of Android Tuner, and benefits from a larger user-base, improved stability and performance.
It now has the ability to turn on/off CPU cores, with a dedicated screen-off option. Only if custom kernel allows it though.
If you have specific profiles in SetCPU and a set CPU frequency NSTools, is there anyway to keep the profiles working without having to disable set on boot for NSTools? NSTools seems to overtake CPU settings on boot.

why do you even want use SetCPU ? it seems to be useless with NSTools because what ever it can do is to be done by NSTools , if you say you wanna do something like change frequency while screen off , then the governor will do it automatically if you choose appropriate CPU governor

CPU Profiles aren't worth it for day to day use. Constant ondemand is perfectly fine and won't steal any extra battery from you.
However, setting NSTools to set on boot should still allow SetCPU to work fine, as long as CPU settings are set the same on boot time. If not, use init.d scripts but remove CPU parameters from them (find them in /system/etc/init.d/xx-xxxxx), keeping the other settings as you prefer. Might want to remove NSTools after this though as it may undo your changes after opening again.
i guess setcpu makes it easier to change cpu frequencies quickly through the widget, ns tools doeesnt have a widget so its "harder"

I'm just a bit OCD about battery life some days. I'd rather use the app than making my own scripts. I kinda derped with the profiles earlier today. All is good now.
I wish the two would play better together too - and I don't see how "just don't use them both" or saying SetCPU is no longer needed is acceptable answers. Especially since many of us actually paid for SetCPU...
Now that it looks like we'll only get two governors in MathKids kernel (what a crock)... saying you are picking the wrong one is a bad answer too. Ondemand certainly isn't the best for battery life, and for those of us who have tested and measured battery life we know just picking one isn't a solution either.
So what is the actual answer? Because setting the governor parameters at boot isn't the problem. It's switching between profiles - and the governors that give you the best battery life and giving acceptable performance need to be tweaked from their defaults.
With OnDemand I'm looking at using over 16% battery per hour under 4.1, even with considerable screen off time. Not being able to set it to Wheatley on screen off is killing the battery.
I will say the problem seems to lay directly with SetCPU and I'm going to contact the dev and see what I can find out. I don't see why it should be changing the parameters back to default on profile change.
But people who use neither or just one probably just not comment. Not to flame, or fight, but it's not helpful to add nothing.
Sorry for my English
I am using CM10.1 ROM
I use the No-frills CPU Control to overclock CPU to 1.2GHz(performance cpu governor). However, when I locked the screen and woke it up, my phone would automatically restore the default CPU setting(1.0GHz). I had to go to the app and apply the setting everytime. How could I prevent the system change CPU frequency?
Make sure that the option called "set on boot" is checked. It will automatically apply the settings (overlclock to 1.2) on boot.
Hope this helped

I have already made a tick. I also found that when I locked the screen for a few minutes, there is nothing changed. And if my phone idle for an hour or even longer, then the system would automatically restore the default CPU setting.
Does the system have battery saving mode? How can I turn off it? I haven't downloaded any battery saving apps
Try.. Trickster mod.. U can lock frequency with it..

Im not responsible for any behavior like the Note 7, if its explodes while applying the tweak its not my fault!
This tweak will edit a simple file so that the minimum cores get decreased and we wont get unnecessary battery drain
ROOT ONLY!
Manual Guide:
1. Make sure your device has root acces,
2. Install Root Browser from the playstore.
3. Open the app and navigate to > sys/devices/system/cpu/cpu0/core_ctl
4. Search for the file min_cpus make sure the permissions are set to rw-r-r (it showsup under the file name).
5. Open min_cpus and change the number '4' to '0', This will say to the CPU that a minimal of 1 cpu core is needed to be active instead of 4 all the time.
6. Save the file and navigate back to > sys/devices/system/cpu/cpu0/core_ctl and change the permissions back to r-r-r.
7. Your device will still run 'smooth' and safe some battery! You have to apply this every single reboot or need to make a init.d script and make it run every single reboot..
You can also use the provided script in the "Attached Files" section. If you use a script runner you dont have to follow the Manual guide everytime you boot.
Share what you think, any feedback is appreciated!
Thanks, so i did the steps 1 to 6, and the contents of that folder disappear, is that normal? I restart the phone and the files appear and i did the same steps the files disappear again.

It shouldnt what device do you have Kiw l21? MM or LP? Open kernel adiutor or something else and see how the cores behave make sure battery settings is on Performance. Not much what i can do other wise..
Kiw l24 MM last update from honor UK support page. For example in kernel adiutor if i want to change the min frequency to 200mhz or any other, the settings won't apply, it return to the original frequency after few secs.
SOT ?? @Demian3112

You cant set big cluster. For small cluster go to sys/devices/system/cpu/cpu4/cpufreq/ and look for min freq set permissions to rw-r-r open it change value 800000 to 200000 save it change permissions back to r-r-r

Havent measured. I safe about 3-8% in an hour doing the same stuff youtube, google, whatsapp and facebook etc. It really depends on what you are doing.
Little cluster runs idle 800mhz with the tweak 200mhz
Big cluster has 8 cores active all the time, with this tweak 0 in idle/simple tasks. It only enables when needed
Just try it out yourself. If you dont like it remove kernal adiutor restart device and tweaks are undone
doesn't seem like little clusters settings are sticking in Kernel aduiter. When changes to 200mhz, it automatically get changed back to 800mhz min

Thanks for the fast response. However, that did not work for me initially. I was able to resolve the issue and it looks like I was able to set the frequency for the big cores as well. As a preface, I have the L24 and updated to MM EMUI 4 through the zip that was found on the hihonor UK website. After the update I did a factory reset. I am just letting you know because some of things you described didn't work while other things did.
What did work was setting the Mincpu to 0, so that when idle only 1 core is running. This worked great, so thanks for that! However, in Kernel Aduiter, I had to set the governor to Interactive for it to use the other Big cores when I am using the phone. If I set it to ondemand, the other 3 big cores does not activate, only core 1 is used along with the 4 little cores.
What did not work per your instructions were setting the min frequencies for the little cores. Yes, I changed the Power option to performance, but every time I exited the kernel auditer, it would revert back to a min frequency of 800mhz.
After tinkering with the phone for a couple of days, I was able to set the min frequency to 200mhz for BOTH big cores and little cores and it seems that both settings are sticking. Throughout the 2 days, I did many changes so I have yet to narrow it down to what changes I did that made both changes stick. When I have some time I will try to reproduce the results and post on how I got it to work. I would also like to give it a few days to make sure that the changes stick.

it disappears because permission was changed to r-r-r which is read only. change permission to include w (write) and execute, and you'll see it again

If i have time i will do it!
Nice tweak on changing 4 to 0 at min_cpus but Root Browser (w/Root and Grant) refused to save it so i used X-plore by Michal Baclk Version: 3.86.02 Build Date: 7/16/16 and it took perfectly!
Thanks for the other kernel adjustments too.
anyone ever make that bat file?
And has anyone tried setting CPU4 the same way as suggested for CPU0? By default, it is set to 1.
I'm also a little concerned I may not have understood the directions properly...
From what I read, it looks like you are ignoring the large cores and only modifying the little ones? Am I understanding that correctly?
And why can't we just tick the 'use this on boot' in kernel aduitor? Why does it need to be reset upon every boot? I mean, we are doing these steps with ROOT access, are we not? Shouldn't the file stay modified? I am quite confused... but very eager to get more battery life out of this... was shocked to see that all 8 cores are always on... and my device NEVER hit deep sleep or any of the slower frequencies all day!
No wonder I can drop to 85% within an hour. Sheesh... this blows.
Ok, I played with it some more...
Looks like Root access has nothing to do with modifying that file. Yes, you need root to modify it... but it never stays changed after a reboot. This tells me that this area must be a hardware toggle area. Meaning, there's some place with the default value stored, and is loaded from there to this location during boot.
I did my best to follow all these steps.
upon reboot, every single thing I put in is lost. Kernel Aduitor seems to lose my settings even if I check 'apply on boot'.
furthermore, all 8 cores are still on.
True, I *do* now see that all the big cores aren't *always* on... but it isn't very different from before doing these steps (at least now I can see a core or 2 shutoff for all of about a tenth of a second)
The little cores... they looked like they took the settings the best... until I closed Kernel Aduitor and reopened it... all the settings reverted.
Yep, waiting with anticipation for some guru who is best at putting something together to set all those freq.'s and such that will apply all of them and keep settings.
Very useful battery mod if it can be made to apply and hold up after restarts.
Yes the hotplug drivers and govenors change it back this is something within the kernal thst you cant edit without needing to flash another rom.. Im on CM13 and batttery has improved quite a bit.. Just give it a try its my daily driver now and its smooth as hell..

Without or before flashing a better ROM, did this item ever get worked out whether by another way to make settings stick or a Huawei small update? Thanks for any advice.
