Hi everyone,
I've got a problem with my Samsung GT-I9300(Galaxy SIII) device.
The problem is each time i install some custom ROM (no matter if the kernel original or not is), my CPU is getting very hot extremely fast, even if i'm not using apps that can use a lot of memory/CPU.
Please tell me what the kind of problem is it and how to get rid of it.
Thanks

Try
1)Turning down the brightness
2)Turning off un-needed apps properly
3)Dont leave your android screen on when not sitting on it
4)Take out SD-Card (when not needed)
5)Dont play on your android while charging
6)Change wallpaper
(if the problem continues Please reply) :fingers-crossed:

No, it doesn't help. I've stopped all the processes every time i stopped using it and so on, but it's heating evenso. [And the check-programm shows that most time CPU was used fully-4 cores, 1,4GHz]

You could try buy a new phone? or exchange it or even try get this one checked out
No.

The most interesting that it's not a phone problem. When I install some kind of stock OS (no matter if it's XXEMG4 kernel or XXUFME7 etc.), everything is OK.
BUT DON'T RECOMEND ME TO FLASH STOCK OS! I'M THE CUSTOM OS's FUN!! :laugh:
Tweak the build.prop for battery related lines...and yea also frequently clear the ram.. And browse the net for prevention of overheating of battery and install the scripts..

No problem with battery. CPU is overheating - I've checked this.
Root your phone and install v6 supercharger. Makes your phone faster and uses less ram so less cpu consumption and less heating

When I upgrade to a newer version of cm11 I often get a blue screen of death or a sudden reboot before the device has finished rebooting.
How can I find out what is causing this ?
I also have a huge battery drain (like 20-25% overnight), Im using greenify for system apps too, RILJ is causing a lot of drain and powermanager too (betterbatterystats, wakelockdetector), any suggestions ?
Maybe I should disable Fast Dormancy ?

As to the first issue, is this only an issue during bootup? If so, that's a known issue, and after it goes through its reboot cycle a time or two, the phone should be fine. If it's happening other times, we'll need logs of the situation to see the issue.
As for this 'huge battery drain' ... We'll need some logs.

Only during bootup after an upgrade/clean install. Good to know it's a known issue. The drain has stopped (using greenify for system apps).
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.

Idk if this is device specific (I'm on the Kindle Fire HD 8 2018) or firmware specific (I'm on 6.3.0.1) but when you freeze or disable these apps your cpu will stay constantly maxed out. it happens on the reboot after you freeze/disable them. if you notice your Kindle is sluggish or losing battery faster then normal it might be these apps causing it. I've frozen pretty much every other amazon system app (other than fireos) and these are the only ones that have caused me any issues. basically just giving a warning for anybody who has frozen them

they are useless to me and did nothing but waste battery I HAD to switch to lineage to get rid of battery draining/cpu wasting apps like that
