Hi to all.
I've just rooted my Tab S and looking for an app to manage cpu clock with stock kernel (I want to underclock it a bit to save some battery as I'm not a gamer).
Any recommendations?
Thanks in advance.
PS: Sorry for my english!

Just use a CPU management app such as setcpu, but it's a bit pointless anyway. The CPU will only ramp up when needed, so if you don't game you won't have high CPU usage.

I'm asking cause the one I use on other device doesn't work on Lollipop (don't know if SetCPU works on LP as it hasn't been updated).
AFAIK cpu ramps up a lot, even when web surfing or reading.
I'm looking for an intermediate state between default and power saver mode.
Thanks.

Setcpu works fine.

Hi all I'm fairly new to these forums, although I have been watching from afar for quite some while now!
I have been trying out custom roms and various kernels and was wondering how do I go about overclocking my device? Only reason I am asking is because I was checking out benckmark results for other devices and noticed some can be particularly high.
Any insight would be most appreciated!
I wouldnt try any overclocking on the HOX because of the heat issues. A more safe and stable way of doing it is changing the govenor of the kernel or forcing cores online. I think you can use core control (in the apps and themes section) to change core behaviour and system tuner to change govenor.

I have now installed core control. Got to admit it is nice having the option to save a bit more power. How much as an estimate do each of cores use anyway just out of interest?

you can download an app called tegrastats to find out more but all you should know is this. once you activate the corecontrol and depending what app you use you should be fine. if i was you i would also use no-frills cpu app. that way you can underclock and would save you more juice

Fantastic! Many thanks for the advice. I have now installed no-frills cpu, and started to tinker around with the settings. Could I ask as I am still fairly new to some of this, when I first went on to the settings both maximum and minimum were set to 1.5 GHz (Not sure if it was just saying this on the app or not or if these are the actual settings) but I would guess this would use a lot more power am I right?

yes you are right. put the min frequency to say 200 or 300 mhz and then press apply on boot and then reboot and you should be fine
Hi!
It's the summer where I live and it's like above 40°C in my appartment (Yeah, I've a free sauna, jealous?), and this cause my One X to overheat all the time, I'm not even doing "heavy" stuff, just browsing the Internet or Facebook via Wifi, I already tried to slow down the CPU to 1200Mhz but it is still very hot, is there a solution to avoid this issue (apart from "DON'T TOUCH IT!"), I can't believe that Taiwan is a cold country and that the HTC was not made to work at 40°C...
You can see my ROM and Kernel above this message (signature) I'm trying to install Viper ROM to see if it fixes the issue... :fingers-crossed:
Nevermind, I fixed it, I used wrong voltage and too low down threshold value in SetCPU which caused the CPU to overheat and stand longer activated, silly me

Could you tell us what configuration you're using? I'm kinda having the same problem.
Appreciate your help.

i would like to know the same thing, what voltage calibration did you use and when you were able to get the temp down to what you liked did you still have good gaming performance?

he fixed nothing, he messed up his cpu settings and noticed it later, so he put the cpu settings back to stock.

Wow, what a up !
Seriously though, I'm not using my HTC One X anymore, but last time I used it, I used Faux kernel with -100 uV and some Ondemand governor tweaks (mostly to lower frequencies at as state that is just above lags) and it was running lagfree and a lot cooler than stock, but I hope you don't mind loosing a bit of 3D perf...
Hello guys!
Is there any way to remove the underclock feature in Xperia S? I know the CPU will underclock itself to prevent overheating but this is just ruining my gaming experience
I'm not an excessive gamer,I play games just around 30 minutes but the automatic underclock is annoying
It makes the game very laggy and barely playable,and I mean HD games of course.
I know that I could always open any CPU app like SetCPU,No Frills,etc and raise the CPU clock back to normal but I just don't want to switch back and forth. I want to play undisturbed
There is a thread here (Yes,I've tried searching before posting) But I'm not sure if it's relevant.
Also,there is an app called "Overheat Control" (See attachment). Is it safe to remove this app?
Thank you!

It really works and helps ,tried it by myself.
Just use set cpu and set the speed between 1000 and 1500 mhz and it won't underclock and lag

I have been using Yureka for few days and see that cpu cores are always on, irrespective of load. Is anyone working on a kernel which can shutdown 4-6 cores when idle or when screen off? I think this would be great for batter.
Try Cpu Tuner, it has options for profiles and to turn off CPU cores after digging into some settings to enable it as far as i remember.
I am using it. However, the current kernel (as well as Sandy) does not support core shutdown so none of the apps have this option. CPU tuner will scale down frequencies to what i want but all 8 cores are always running.
Like this?
How did you shut down the cores please tell us..

Can you share your configuration from CPU Tuner? I can't any option in cpu tuner to shut down cores. Only governors and their affinity settings.

"Simple and Powerful" Config with "Power User" profile.
My CPU tuner was working in non power user mode . Thanks for the info. I can control cpu cores now.
Now only if someone makes a kernel with more governors and automatically shut down cores on low usage . It seem cpu tuner only allows me to set number of cores for a profile.

If I am wrong correct me, if I have understood what you are trying to say, you most probably wish to use the feature where the idle cpu cores are shutdown once the load is not that much.
In my knowledge, that's 'Hotplugging' right ?? coz it more or less does the same function. Try installing some custom kernel that provide you with some really good hotplugging governers. And coz the development for yureka is really in it's full form, there have been few kernels that have been posted in the "Original Android Development" section of our xda forums. Try going through them, you will find what you are looking for !

Yes sir, hotplugging kernel is what i am looking for. Last time i checked, there was just Sandy kernel which did not had this. It seems there are a couple more now . I will give them a shot and update.

WHICH KERNEL u r using for hotplugging?
i've been using this phone for about 2 years now and recently moved (about a few months ago) to using a custom rom (crdroid 7.1.2). it was running smooth and cool until day the clockspeed decided to lock itself at 2000 MHz (checked using cpu-z). I do not know if this is normal but the phone's temperature goes up to 36C on idle. i thought the problem was with the Lspeed app (+custom kernel) so i uninstalled it but it didn't work. I also factory resetting it, but still not luck. will updating the firmware resolve my issue? if not, what other available solutions are there?
have you thought about flashing the stock kernel ?

I do use a case, but hasn't been this hot before recently, and it does tend to hit 40C when charging

If you are using Fast Charging, that heating is entirely normal (happens to me too)
But heating during idle is not normal. Try changing CPU governor to something else. (like schedutil or powersave)

Do you know how to change cpu governor? I tried doing it last night but didn't find a whole lot of information. Schedutil seems to just set it all the way to 2ghz, so I want to change it to powersave

use Rootify, select the CPU tab located at the top then change it.
The app sometimes gets stuck at Loading screen though.

ok so it does work when i change the cpu govenor, but the only option that actually works is 'powersave' (as well as 'userspace'). all the other ones still sets it to 2GHz. 'userspace' seems to have a somewhat of an improvement but it's only setting everything to a constant value. is there a way have it set to balanced mode?

powersave forces the processor to work in the lowest frequency availible, thus consuming less power.
userspace allows the app to set the CPU frequency whatever it wants. This isn't supposed to be used in Android since changing CPU speed thorough an app is super uncommon.
Others like ondemand normally keep the power low but starts using the higher frequencies if a processor intensive app is launched.
You can learn which governors do what in this post so you can set the most suitable one for you.
