Power save cpu limit not working?? - Galaxy S6 Q&A, Help & Troubleshooting

I'm on G920IDVU3FQC5 May security patch & no root. Since last update I've noticed slightly weird behaviour with my phone like unexpected lag, then smooth, scrolling issues, memory leak.
Didn't notice that cpu was not limited to 70% in Medium power saving until I opened cpu-z. The a57 cores still go to 2.1 ghz. And I've de/reactivated cpu limit, restart the phone, wipe cache partition in stock recovery with no improvements. Maybe it was a bad update from Samsung.
Anybody having the same issues?
EDIT: It's now working!

Weird CPU Clock behavior

One more problem for my Sensation...
am I the only one who has his cpu always at maximum clock speed with almost any governor (except conservative), when the screen in on (when off it goes to minimum clock as it should), and there is minimum cpu usage?
I tried the latest ARHD (stable) and InsertCoin, the issue seems kernel independent as going stock or with another custom one changes nothing.
After wiping and flashing all seems good. After restoring my backups all seems good. A few hours later the issue starts and removing or freezing the apps does not solve anything.
Battery life is still decent, but this does not happen with my DHD or any other phone I previously had, so I'm a bit puzzled. My Current Widget readings are a mess so I cannot use them to understand if I can fully ignore the issue or not.
UPDATE:
Nevermind, seems that cat-ting the /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq while connecting to adb ramps up the cpu so fast that it seems already at high clock! I must have been confused by the fact that when System Panel shows the clock, it is always high because of the app's "weight"...

[Q] Reboot, crash, freeze tracker?

Are there any apps available tharly can runin the background and track when my phone reboots, crashes or freezes? How about logging battery usage?
For some reason, my Dell Streak has been having issues lately. To try and fix it I have even reset back to defaults and reinstalled the firmware.
What has been happening is...
- freezes when the phone has been sleeping. Requires a battery pull.
- random reboots.
- getting extremely warm in my pocket and draining the battery.
Since the phone is dead or reset, I can't determine what was happening when the problem happens.
CPU Speed
My Phone was doing that same thing. When I installed an RCMix3d kernel it nearly doubled my CPU speed and was making my phone crash and freeze all the time. Once I got SetCPU and set up some profiles to lower my CPU speed to something it could handle everything has been smooth sailing since.

Why my android CPU clock is running at max speed?

Hi,
I own a micromax canvas elanza 2 , unrooted and bootloader locked. I recently noticed that my battery is draining too fast. so to check ram usage i downloaded an app called system panel and it showed over 80-90% ram usage and full clock speed (1190mhz).
I tried factory resetting and rebooting but it only resolves ram problem (that too again goes to 80% usage after sometime). My clock is still at 1190mhz.
please help me.
Thank You
Have you installed an kernel or tinkered with the cpu settings in any way?
No, I haven't installed any kernel. But yeah, once I installed an app called game booster 3 by its rating(4.7). It has three modes but all for rooted users. Those modes said that it would make all my cores run but I don't think it would have any effect since my phone is unrooted. I tried boosting but no significant change on the game. So I uninstalled it. After then also my phone was running fine.

Wait a minute, what cpu do you have? I recenetly updated my tablet to android 6.0.1 and I have a snapdragon 400. Could you tell me which version of android you have? (I have android 6.0.1 r3, buld number mmb29m

I'm having the same issue too , I've a dual core cpu with a frequency of 1.3ghz and all cores are running at their max , please is this normal ? But they isn't any form of overheat or battery drain

Mi4i - Only Four cores are running most of the time, resulting in lagging performance

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.

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.

Heat after root

I was looking for a similar threads but didn't find any. So the problem is that my phone gets warm after root, (also it has less free ram available) I am not doing anything special, just normal magisk installation + kernel sometimes. No matter how I set frequencies in kernel manager, device still gets warm during simple phone usage like messaging/web browsing etc. Am I doing something wrong or this is just side effect of rooting?
Fixed, heating and low ram was happening because of the wrong settings in kernel adiutor. I was setting max frequencies at 1590 and this was limiting big core frequencies also - they have 2150 MHz maximum. There is an app in play store https://play.google.com/store/apps/details?id=com.dsmartapps.root.kerneltweaker and it can help with that.
