guys...my phone sometimes freezes on the lockscreen....and I have to pull out the battery...the problem is that this happens with all roms, sense or not based....
what's going on?!
You may get more help if you provide a little more info, ie:
-Are you using a specific 3rd party launcher with roms?
-Are you using a custom kernel, and if so what are your settings?
-Have you tried running in safe mode to rule out 3rd party apps?
-Did this problem begin after anything in particular you can think of?
-etc....
Maybe too low CPU values?
Undervolt can cause this as well.
It happened to me while using APEX on ARHD.
But indeed more info is needed.
this started a week ago...with miui official/faux kernel and now with aokp b38/tamcore kernel....I know tamcore kernel is undervolted, and don't know nothing about faux's one...
I use nova launcher, setcpu is set at 384/1188 and I have a profile screen-off at 192/432...
uh, forgot, I use SIO scheduler...I set it with no frills and uninstalled it after, to have just one cpu control app (setcpu)...
this morning my alarm didn't ring! then I had to pull out the battery because it was freezed...luckily I woke up by myself this morning XD
I recommend to use a higher off-screen value (384 MHz) as a first try. See how it reacts and also use an app to check the current voltage (like system tuner / st pro).
If this does not helps then start isolating apps.
I have NOOP sched and 384-432 Off-screen and had no issues far, but I remember that with 192 Mhz a while ago the screen did not wake up a few times (on ARHD 6.3.x).
I updated to b39, nothing now....if it freezes i'll try setting a higher minfreq...
thank you all! thx+1
Hello,
Mi 4i lags/slows down most of the time, when i check CPU-Z during that time, i can see that only the lower clocked 2/4 cpu cores run constantly at 800 Mhz. It is very difficult to use when it is so slow. Other 4/6 cores remain inactive.
Is there any solution for this weird behavior while running in Balanced mode. Even when switching to Performance mode, nothing changes. I believe due to the heat generated, the OS automatically underclocks the CPU. I have already rooted and tried changing the CPU Governor, Clock speed but it resets to default every time. Sometimes i am unable to change that too.
Thank you.
There's a configuration that does this, just try to use the provided tweaks available here and then configure the phone's cores and so manually.
http://en.miui.com/thread-140563-1-1.html
I tried tweaking the thermal config using the above thread. But still only four cores are active @ 800 Mhz. The phone is so lagging that it is not usable at most of the time. Unable to change governor in any CPU clocking app, turn on the other cores. If you can help me out, please let me know.
Thanks.

Might be a bug. Try a clean install and see
Same here
I am having a similar issue, very frustrating. I tried Sensei kernel, but no luck
i don't know what do you mean bro
everytime i change to other rom,other kernel
the results is...
all core is on

strange, i am using miuipro with sensei and havent found any problem.
This happens in the latest stable MIUI7 ROM. I think it is time to change to a custom rom.
Nexus 6P - Stock - ElementalX Kernel - 7.1.1
While using the ElementalX Kernel Manager app, it will not save my governor profile that i have chosen to use after a boot. I have apply on boot checked next to literally everything in the CPU tab to be sure it is set. The CPU governor is set on boot, and no apps i'm aware of are interfering. I use greenify, but the kernel manager isn't being greenified. Specifically the touchboost setting they won't save. I have touch boost disabled, and it does stick after boot. But when i go into the app, after a boot, it jumps to 1300 hz like i didn't apply any settings! As soon as I apply the governor I want to use, it works and the profile does stick. The problem only happens AFTER a boot. Some settings do seem to stick around, like for how long the cpu will stay at 1300 hz after i touch the screen. Currently using Glassfish 1.2.

Greetings and welcome to assist. Unfortunately this is not something we can really help you with, you need to ask in the kernel thread
Regards
Sawdoctor
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.
