Hey,
I am suffering from high CPU usage, bit only on the big cores.
It is always above 50%.
Can someone help?
Thanks

Are you using Custom Kernel?

Yes, radon kernel, but I get the same results with stock lineage kernel.
--------------------------------------------------------------------------------
One core is at 100% usage and other at 0. Hence average is 50. I don't know what to do.
CPU z shows the are normal, maybe it is because of kernel auditor.

I have a doubt: when not in use, the CPU is downclocked or work at 1.2Ghz.
If it isn't downclocked, there an app or something else that could be that? I think that could be usefull to improve battery life.
Download CPU Spy to monitor the CPU. It should go into deep sleep when idle.

Normal settings are for it to only run at 1.2 GHz when loaded. Also, in addition to downclocking, the CPU can go into "deep sleep" where everything shuts off.
The specific clock management settings can be tuned with an app like SetCPU.
Stock frequencies are 200, 500, 800, 1000, 1200 MHz.
I'm wondering if there's a way yo improve battery life... maybe it's better to install a custom rom?

Most people seem to gain battery life on custom roms. There are several to play with and, once you get over the initial hurdle of getting one installed the first time, you won't want to go back!

A couple options which I do myself are run all speeds undervolted by about 50 and set Max speed at 1000Mhz. Not sure if it makes a huge difference on battery life but it definitely doesn't ruin the performance, that I can tell.
Sent from my SAMSUNG-SGH-I777 using xda premium
Even 800 doesn't ruin the performance enough to start caring. Once I jump a new kernel I'll start tweaking undervolting and even crazier profiles.
Install a custom rom that removes bloatware and known battery drainers, and undervolt the cpu/downclock it to save most of your battery. Theres many threads about battery life, I suggest you look though those.
Hello all
I have a bit of a small problem. I like to run my phone using the Performance Governor but after a while it goes to 1Ghz on all 4 cores despite me running it at 1.8Ghz. Setting it back seems to correct the issue but in time it goes down again.
I believe it is getting a bit warm and thus it hits a limit and the system auto slows to 1Ghz.
Can anyone confirm this behaviour? It never happened to me before but I have had a few kernel updates and updates to the Omega ROM that could be the cause but I am not sure. Is there a setting where I can tell my phone what temps to throttle at?
Also, I assume all this is down to the Kernel and not the ROMs?
Would like some imput regards where to start my search to return my phone to its previous state as a pocket heater.
Many Thanks

Don't use it. Pegasusq is the only one really working for multi-core CPU's with hotplugging and so on.

1.8Ghz is not healthy for the CPU in the long run and will cause overheating which is exactly what you are currently seeing.
Especially since you keep the phone on 100% CPU power all the time (performance governor) which should drain battery like hell as a side effect.

This is down to your settings. Neither rom nor kernel.
- Don't overclock (much)
-Use a good kernel such as Siyah
-Undervolt if the phone remains stable
-Use pegasusq Governor
-Enjoy

Hi buddy and thanks for your response.
I am not sure about what you said regarding it working correctly, it gets the best results for any benchmark compared to others so I would be interested in more detail about the specifics of how its not working correctly as I have never been told that. It would be appreciated.
I dont mind the battery drain although I do heed your warning about about longevity of the CPU.
I have been using Siyah Kernel for some time now and I find undervolting a little unstable, for now I am forced to use pegasusq.
Can you or anyone else answer the original question as I still wish to pursue this to a resolve other than not using it.
Many thanks for your time and efforts non the less!

it´s samsung´s based roms related: when the battery temp hits 41C the cpu will throttle. Nothing related with de cpu temp (can be at 80C before throttles).
try CM10.1 and you´ll see what im talking about.
We need a solution for this throttling with samsung based roms

That's the great thing! Really the worst that can happen is your phone freezes or reboots. Once you have undervolted your CPU to just above its freeze/crash levels, there are no disadvantages!

No, as it is completely device specific. There are tolerances in manufacturing process, and u have to figure out the values for ur exact soc

I have PVS 13. Is that good?
I am using ashwins cm13 @ blue spark kernel, undervolted and underclocked to a max of 1497mhz. My phone runs a lot cooler, charge faster, and I can constantly hit 5hrs plus sot, sometimes I even manage 6hrs sot if I am only using im apps and this is all on mobile network and never on WiFi. So with WiFi i could probably hit 6hrs constant.
Is the bofella kernels 2.2 /1.8 ghz over clock is stable I am getting freezes nd random reboots
But on benscholds its pretty stable at 2.05 ghz / 1.7 ghz
Any solution ?
do u have clean cm 14.1 + opengapps installed? no more tweaks and weird apps?
and by weird, we mean Xposed.

Not necessarily, if they want the best camera performance then they need to wait for OnePlus to release binaries for Nougat.
You could try messing with voltage (I'd only suggest slight adjustment), using the app Boeffla provides here: http://www.boeffla.de/index.php/downloads/boeffla-config-app
But I wouldn't recommend a super high overclock as the 810 can overheat pretty bad, also depending on your governor (I use elementalx)

If it's available for your kernel the Boeffla-Config app has it under the CPU tabs at the bottom.
But as Sungfive claims it's not available, it probably isn't, sorry if I was misleading. I remember now Boeffla even says in his thread he doesn't allow voltage control anymore in the kernel, stating that you can add it back and build yourself if you want it (not so simple of course).

The big.Little architecture doesn't allow changing simply the voltage
Clean flash again the rom and the kernel
If you want better performance then don't overclock.
Hi all,
I have a problem with frequency scale down for higth temperature.
I am from italy and now the temperature in My House is 30-32 celsius.
The smartphone temperature is 55 cpu 50 gpu 40-45 battery also if use The max 2 only for browsing.
I tried to set the frequency 1700 for the big core and 1400 for the little but nothing changed.
Is normal?
How i can down the temperature?
Thank you
Nobody have this problem? Only me?

Try flashing the BlackScreen kernel. My room temperature is about 35-38 °C and battery temperature is around 37-42 °C with medium to heavy usage. The temperatures you mentioned are normal IMO. Until they are below 43, it is fine.
PS : I don't know if the last RR comes with BlackScreen built-in.

With the rr i have flashed bs 2.7 and after 3 but with previuos rom haved the stock kernel.
The problem is the same.. If i play or browsing the frequency scale to 1400 for big cpu and 1090 for little cpu and 310 for gpu
You have the same problem?

Yeah. The phone heats up about the same temperatures for me too. With the stock Leeco EUI software, I had heating between 35-38 °C (battery temperature) so I consider it to be normal now. Actually I'm adapted to the temperatures on Nougat ROMs now.
But you "Block" the frequency of your cpu/gpu?
Instead of limiting your frequency, can you try changing your governor ? To power save etc...

I tried some governor and the problem is the same.. Over 50-55° temp the cpu frequency scale down to 1400 or less
I tried with kernel adiutor set up the "warning temp" from default 70° to 75° but nothing is changed
Tomorrow try with other governors but i think with the same results
Battery temp is 35-39 for me while browsing. 41 while playing games and charging at same time. You should wipe data reflash and and start over

I agree with unrafa, reset everything and/or install another rom. I on crisbal s 26s v5c it is all fine here... Has your phone repaired at one point? Maybe a thermal paste not applied etc...

Now i cant change the rom because im on vacation but i think is equal because i have the same problem with stock rom, cuoco92 rom and madlemax rom

I have an older version of resurrection remix more battery friendly, with BS kernel, alucard governor and alucard hotplug, it's said to be very battery friendly and at the same time keep phone smooth. Shuts down cpus when there is low payload and turn them on while needed
As you can see the frequencies while playing the game are never at their highest, only very intensive tasks put all CPU to highest frequencies, no lag very fluid
Here is the ROM: https://forum.xda-developers.com/le...x-resurrectionremix-m-v5-7-4-t3542355/page423
It's an amazing game you should try it
