Ive seen an undervolting option in systemtunerpro and ive seen people talking about undervolting.
what will it do to my phone?
if so what should I under volt it to?
the app has 2 buttons that add or subtract 12.5(I think I can't check right now) to all the values at one time. how many times should I press it?
I've searched but cant find nothing
rom is Prime 5 with bricked kernel 1.0 badass gov

If you do it right your battery lasts longer and your cpu will be cooler.
It means that the cpu needs less power than normal. But every cpu is different, so you can probably not undervolt that much like someone other.
If you want to do it right, try this:
Search the App "Stability Test".
Then go into System Tuner and look, which Cpu-Freq. are needed most. These are the ones on which you should focus on to undervolt.
First you can set all freq. -25mv, then run the "scaling stability test" in the stability test app. If your phone doesn't freeze in the next 15 min, you can set -25mv again. Do this until your phone reboots or abort the test itself. Then set it 2 steps above the values which didn't work to prevent reboots.
Now you should change only the freq which were used most. But only one after one. If your phone uses (for example) 192 mhz, 1,08ghz and 1,5 ghz most, first undervolt the 192mhz (again till your phone reboots or you can't set it lower).
Then the same with 1,08 Ghz and then 1,5Ghz. If your phone reboots, set it 2 steps above the value which didn't work, so you can be sure that your phone doesn't reboot again.
If you found out which values your phone can handle, go into "System Tuner", CPU, Voltage, Boot settings, then "Re-apply CPU Settings". For the first time you should set it to "On boot completed", if you didn't notice any problem you can set it to "init.d script".
If this doesn't work for you, go back to "voltages", then hold "reset all/clear" till it changes to "save defaults". Press it once, so your values are set as defaults. If you rebooted your phone you have only to go into "System Tuner" and press "Reset all/clear" once, then it will set your values again.
I hope my englisch is good enough to understand it
Hey there guys!
I'm a happy owner of oneplus for about 3 weeks now but I noticed that after a few days of usage the device slows down gradually, up to a point where using it is quite troublesome. Also the wake up button seems to fail at times, where I have to press it 3-4 times to wake up(today it failed to wake up and I had to restart it). Any idea what might be causing it? I'm on the CM11S newest update, no kernel changes whatsoever, interactive governor and TWRP installed.
Thanks in advance!
I'm running PA 5.1, facing a similar issue. Capacitative buttons light up immediately after pressing the power button (or double tap) but the screen lags for about 2 seconds.
Sounds like your cpu min frequency is set below 300

That's impossible on stock.

Nope. Done nothing of this sort. Moreover, the lag occurs only if I wake the phone after 3-4 minutes of screen off. If I wake it immediately after turning the screen off, there's no lag.
PS: I'm on AK Kernel 300.
When I use ANY CPU control app on ANY ROM on my D850, the set CPU min and max frequencies are reported as a random interval between 300 and 960MHz, and the only way to get it to go back up is to restart the phone and apply as soon as I start it. I can hit apply 100 times in a row, and the frequencies set are different each time. The min is always 300, but the max is completely random.
The different integrated CPU control apps in ROMs simply don't work at all, that's why I'm using a 3rd party app.
Any ideas? My performance has been absolutely terrible randomly on and off since I installed candy5 a few months ago. Most of the time it's fine, but sometimes it's so frustrating it takes a lot to not throw my phone into a concrete wall.
I had the same problem you had until I used fauxclock. It's expensive but it worked for me. I also own a D850.
i have the 1689mhz bug!!! at random time the MIN freq of the cpu is stuck at 1689mhz andthe max still at 2ghz. ( you can activate on developer options the "show cpu info" toggle)
i cannot change the min value from kernel adiutor, i click on 652mhz but nothing changes, only a REBOOT actually fix the min freq used.
i thought it was a problem of my custom rom resurrection 5.8.3 or the fact i am using kernel adiutor, in fact this app does randomly give CPU LOAD BUG on several devices i mod! sometimes kernel adiutor load my cpu cores at 100% also on light load, but just forceclosing the app the cores return to lower freq.
but the 1689mhz bug is a KERNEL BUG, i read about this bug also on people with stock rom, and the p2a42 phone.... and i have p2c72 hardware phone!!! so this kernel BUG is found in EVERY VERSION of this phone.
please developers, we need a modded kernel that fixes this bug, and why not.......... new i/o schedulers and governors.... and maybe a little undervolt for every cpu freq

Haha! Have very less hopes,bcoz some feel that custom kernels are not at all needed! They think that a device wid 2ghz processor doesn't need custom kernel
And btw the post topic is 100% right,bt the place where it's posted is wrong! This should be under discussion section

Yes, thats true. The bug is i think VDD related. Sometimes the VDD switches automatically on, the min CPU freq goes up to 1689 MHz, and can not be lowered until you don't switch off the VDD. You can switch off in Kernel Adiutor/Thermal section, or use the following command :
echo '0' > /sys/module/msm_thermal/vdd_restriction/enabled
I use the KSLABS Schedule! app to run the command every 5 minutes.
I hope this will help you, until we get one bugfree kernel.
u are right
now the bug is MORE AGGRESSIVE THAN EVER............ i rebooted, i attachedthe phone to a charger, arrived 100%, then rest for 1h30min on idle(deep sleep) but when i started using the phone... i checked the frequencies and BOOM....... another time the bug of 1689mhz!!! the battery was 100%......
maybe there is an app that causes this... but which one?

Which ROM do you use?
I have stock 244, but the method worked for me in 233 too. In the past, I used the Magisk Crossbreeder Lite module to eliminate this problem, but the latest (1.6+) versions made the phone very slow, especially booting.

can you help me with the console command... but with macrodroid? i don't use that app
edit_ i setted your app, ibut i prefer every 1h to toggle VDD off

Maybe the Kernel adiutor itself cause the high load, as background task make 28-30% cpu load, see the attachment.
But, the 1689 MHz bug still exist. :-\

what app do you use to see the % of cpu for each thread?
i don't think that the cause is kernel adiutor... i repeat, a lot of people with 100% stock rom have this bug.....
hey vis could you help me with the string of the scheduler app? i don't understand how to set every 1 hour my previous screenshot i think is wrong because it does not work every 1 h
sorry but the "cron expression" is too much difficult to me to understand.....
EDIT i found how to do every 1h!! 0 0 0/1 1/1 * ? *
thanks to this site!!! http://www.cronmaker.com/

The app name is 3C Toolbox Pro.
Yes the bug is still here, Kernel Adiutor is only different problem.
After reading all your discussion.. I understood that one of you knew solution to stop the bug ,and the other guy learnt how to do it ..
But I don't get a single thing ,what and how you solved that bug
Note : I don't even know that 1698 bug is present , all I know is cpu idle is consuming more power ..
Is this the same thing you guys were discussing?
If yes ..how can a I solve it ? Any walkthrough?for dumb minds like me ...?

I've made the following observations:
On a fresh install(stock or custom rom(i have not tried Firelord versions)), rooted phone(with Magisk or SuperSU), if you install the Kernel Adiutor, and go to Thermal section the VDD restriction by default is OFF. You can change freely the CPU minimum frequency.
After some hours/days(total random) something switch ON the VDD restriction, the CPU minimun frequency going up to 1698 MHz, and unable to set back the default 652 MHz. If you switch off the screen the cores going to deep sleep, but if you switch on the screen the min. freq. is still 1698 MHZ.
If you manually switch OFF the VDD restriction, the CPU working normal, until switched ON automatically again.
If your phone is not rooted, the only thing what you can notice that the battery is dropping faster than usual, or the phone a bit warmer.
The problem still occurs even if you do not have a program that you can turn on/off the VDD.
The above solution does not repair the problem, it only remedies the symptoms...
I sometimes notice that even though I don't use it, "Google Play Services" consume an unusual amount of battery and will continue to do so unless I reboot the phone. I have never investigated the cause. Might this be related to the 1698MHz bug ?

I do not think so, but check the status of VDD when you have rooted phone. Sometimes I have too huge battery usage caused by the Google Play Services, but i would suspect first of the Location services. If I use some sport tracker, or navigation app then growing for me the Google Play Services consumption.

My phone is rooted. I will start monitoring VDD. FYI, I don't use any google app (Gmail, Play Store, Maps, etc ...). Location services is also turned off. Sometimes, out of nowhere, I'd see Google Play Services at the top of the battery consumption details. Yesterday, it had a very high CPU consumption time of around 1h (prevented the phone from going to sleep; had 3000+ wakelocks). I had to reboot the phone to get it to stop eating my battery. Usually, Google Play Services use the CPU for a total of 10min on a full charge.

If you don't use it, you can remove what is mentioned on the MicroG Prerequisites page[0].
Some apps nag about it but the only noticable problem I have is messenger lite notifications don't go automaticaly away after replying. Even my banking app keeps working.
