Hello
Is there a application that allows me to, for example, when motion has been detected to the screen the default speed is set, while if no motion has been detected the CPU is set to 75% and when the screen turns off and the phone is locked, the CPU is set to 30% (all of these are examples)
Something that automatically sets the speed when different conditions happen. I believe SetCPU cant do that.
Thanks
SetCPU. You can set yourself the speed of the core cpu when the screen is off, or when you're charging the phone. Other than that. Your CPU actually knows when to increase the core speed and when to lower it down.

It does exactly what you're asking for. Use the profiles feature for the screen off setting. Otherwise, it automatically scales based on usage.
SetCPU can't set speeds by gestures/motion as far as I know. It can only do charging status, screen status, battery % and temperature...
For maximum flexibility what we need is a Tasker/Locale plugin that can change the CPU speed. Or maybe you could program Tasker with intents?
Hi, all!
Some people, like me, may have downloaded a cpu-monitor app like System Tuner then notice their second cpu (cpu1) always appears offline.
First off, I recently realized that that is often inacurate. Using another app like SystemPanel would show both cpus being online, and more importantly, checking sys/devices/system/cpu/cpu1/online would show it's "1" indicating online. Many cpu app's inability to read cpu1's info is because "cpufreq" folder is missing from cpu1 folder (if you check cpu0's cpufreq folder it's always there).
K, now also, some poeple like me, thought cpu1 was really offline, and used System Tuner's "Force all cpus online" option, and viola, after reboot the second cpu showed up. But why? Cuz a "cpufreq" folder is found in cpu1 again.
What is interesting is both files "affected_cpus" and "related_cpus" would show "0 1" meaning the two cores are in sync and if you change settings(freq,governor,etc) for one core it automatically changes the other.
Now here's the tricky part, however after the tablet goes to sleep, when I wake it, cpu1's "cpufreq" folder would disappear again, meaning Sytem Tuner would show cpu1 agains as "offline". But if you chekc "online" file in folder you'll see it's still online ("1") and SystemPanes still shows cpu1 activity. However "affected_cpus" and "realated_cpus" will show only "0" meaning the two cores are no longer in sync.
Conclusion: so far what I deduced is my tablet in its default state has both cores online, but are off-sync. After turning on "Force all cpus online" and rebooting, they are both online and in-sync. After the device goes to sleep and wake, the two cores are still online but now off-sync.
The important thing about this investigation is how much it affects 3D performance. I was always confused why my device lags with a aged-game like Counter Strike portable but is perfectly smooth in a consol-quality game like Mass Effect Infiltrator. My current thought is Mass Effect acttively tweaks your cpu while most other games leave cpus as they are.
Benchmarking (using market benchmark apps):
(First off, the FPS difference may seem small but in running the actual games for some reason it made a enormous difference, often the difference between crashing and not crashing/playable or unplayable in Nova3/Shadowgun)
Default, newly flashed rom: FPS :33 (Some games fail to load graphics properly for some unknown reason)
Turn on "Force all cpus online" with Sys Tuner: FPS 39-40 (All games are silky smooth, no errors, tablet temp hotter)
"Force cpus online", then after wake from sleep: FPS: 33-34 (not as smooth before sleep, but games generally load properly)
**Switching my cpu0 gonernor to the same governor I think cpu1 is using: FPS 35-37 (no errors, almost as smooth as "Force cpus online")
Here's a crappy surprise --Cpu1 off (turn off dual core): FPS: 39. (Completely smooth, zero errors, hottest tablet temp)
**after cpufreq folder disappears from cpu1 I cannot be sure which governor cpu1 is using, but checked with Kernel Tuner and believe the system switch it back to "performance2" which is a governor foudn in my tablet.(it it not like "performance" governor) upthresh 60 downthresh 30 freqstep 5.
Conclusion:
This leads me to the conclusion that having both cpus online does not necessarily improve performance, but if the two cpus are off-sync it definitely BUTCHERS performance. It does so so badly that running one core is actually better.
Need help:
I hope the info so far may helped some people, but the help I also really need is someone to tell me how are "affected_cpus" and "related_cpus" controled by the system? So far I had no sccucess modding their values and forcing cpus to "sync". I enter "0 1" but it doesn't go through. Since having the cpus in sync seems to give good performance and lower temp (single core was good but temp was noticeably high), I want my cpu cores to remain in sync, but currently it undoes the sync after waking from sleep. I need to understand how and why the system somtimes decides to coordinate both cpus synchronously so both cpus appear under "affected_cpus" and "related_cpus"?
Thanks to anyone for reading!
I am trying to figure all of this out myself and will be performing more tests after I root. Thank you for the info!

setting cpu governor for all cores irrespective of their online status
i am stuck at the inability of kernel to allow a one point settting of scaling_governor for all cores. I tried with a for loop to echo, in each core's
cpufreq module, a scaling governor, but failed for offline cores as they have no cpufreq folder when they are offline. I tested cpu tuner app and it does the above said amazingly well. I would like to request anyone to help me in knowing,
how to programatically set cpu governor to all cores irrespective of their online status?

I see these three options I'm various kernel tweaking apps and just curious what each one does.
Core control is usually enabled and the app has a warning not to use more than one all though I've used various combos of the three with no difference.
Thanks
Did you find the answer to this? I've been looking for this as well.
Core Control : Enable / disable throttling, this enables the thermal engine and enable VDD restriction and core throttle
VDD Restriction : Limits CPU voltage, limiting it will decrease temperature
Core Throttle : Throttles CPU when enabled, this decrease CPU frequency to a lower step when it reaches a specified temperature
// This is all I know, btw. This could be wrong, so I advise an extra Google search just in case
Wondering this as well, which one is best?
Sent from my LG-H811 using Tapatalk
As far as I know it's a way that kernel manages the cpu...so it won't burn.
When cpu gets hot it will limit the cores (core control) or their frequency (core throttle)so it will decrease cpu usage and makes it cooler...
Both will impact cpu at high temperatures but having them on is an insurance that you won't melt your cpu...and having 2 or three enabled will limit cpu cores and frequency so it will be snail speed at high temperature (will cool down sooner but it impacts cpu very high... And may get bug)
Suggest to set core control and as long as you maintain temperature...none of them have any difference.
these thermal driver is not thermal throttling disable it can't get rid of thermal throttle, these driver control cpu frequency between cpu governor. core control is for low end phone base on mpdecision and replace it, but core control never unplug any cpu core when idle. useless driver

- In Thermal settings of Smartpack Kernel Manager enable SoC Temperature throttle instead of Core Control.
- In Smartpack Kernel Manager set CPU governor of little CPU to something like "relaxed" if your ROM/Kernel Supports it (on crDroid for example)
- In CPU hotplug settings of Smartpack set minimum of big CPUs to 0.
Make sure to enable those settings in Smartpack at boot with the Switch at top of the corresponding Module in Smartpack.
And you need root/magisk for these Kernel Tweaks to work.

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.

Tuning Battery Life on Samsung Note 3 N900
I don't have a device anymore, but I still wish to share my experience and how I achieved 6 hours SoT with my typical daily usage on this phone.
This guide is for CM12.1 / AICP 10.0 (I recommend latter, it's the same CM 12.1 but with more options).
You can try this settings on aurora/stock ROMs with respective custom kernel (Suemax).
First of all, you need a kernel with Synapse support. This section is for CM12.1/AICP only! Don't try to flash these kernels if you are on Aurora/Stock - you'll have bootloop!
-- Download Stock and DJMax81's V2 kernel from this post and Suemax kernel from this post.
-- Make a backup
-- Flash CM12.1-DJmax81-Kernel-Lite-V2.zip
-- Boot your phone once and open Camera app to ensure it works.
-- Reboot to recovery and flash CM12.1-SueMax-Kernel-V3-By-DJMAX81.zip dirty. No need to wipe cashes.
-- If you encounter issues, restore backup or flash CM12.1-Stock.zip to return to the stock CM12.1 kernel.
Now you can fine-tune your Exynos!
First, disable touchboost. It's some sort of cheating Samsung use to make it's touchwiz not so laggy. On stock Android you simply don't need it, even if you set max CPU to lowly 250 Mhz, Stock Android UX is still decently smooth.
How to do this: open Synapse, go to the QoS tab. There are many, many sliders to control boost in different situations. Slide every one of them to the left. Now you gave full control of your phone freq to the governor.
This setting alone gave me up to 1 hour of SoT when texting or browsing. Because these are not demanding tasks and there's no need for CPU freq to ramp up.
Second, set min GPU speed to 100 MHz. This will save some juice when idle. Go to GPU Control in settings and set the corresponding Min freq slider to 100 MHz, then apply (you need to push the Set GPU settings button and a tick at the right top). You can also adjust Max GPU freq to suit your gaming needs. The more max GPU speed, the better gaming perfomance will be and the worse battery life in games (600 MHz stock value).
Third, let's go to Kernel Adiutor and here are some profiles for you that I found best!
Max Performance profile: Use zzmoove governor, max CPU speed to 1900 MHz, and at advanced governor settings set disable_hotplugging to 1.
Exynos hotplugging has rather negative effect on battery life as I found from my tests, you should never use it. If you are reading this and on Stock/Aurora ROM: disable hotplugging. It makes your battery life worse! Here is the test on Snapdragon 801, on Exynos hotpluging would yield even worse results because CPU with less core active will spend more time on unefficient A15 cores.
Zzmoove is the smoothest and fastest governor I found that still uses all available frequencies wisely.
That's the profile one should use for heavy games (and also set max GPU speed to 720 MHz in Synapse if you need it).
Performance profile: Use Interactive governor and max CPU speed 1900 MHz.
Interactive governor proactively ramps CPU to high (but not highest freq) to ensure great smoothness and still yield not-that-bad battery life (I had usually 4 hours SoT with 2G). For better fine-tuning you can go to advanced governor settings and set hispeed_freq to something in the middle, 800 MHz for example (but not lower than 800). hispeed_freq setting is the intermediate cpu speed which governor uses when there's initial load on cpu.
Balanced profile: Change governor to Ondemand, max CPU speed is still 1900 MHz.
You shouldn't worry, with touchboost disabled it would rarely ramp up to max speed, most often sitting on energy-efficient A7 cores and sometimes ramping to 1200 of A15, going even higher only when needed - still gives you whole power of your device without restrictions. DJMax81 did great job tuning this governor to our needs. You still can set max CPU lower (to 1400 Mhz) if you wish to conserve battery more on this profile.
Power saving profile: Go to Synapse and enable a slight touchboost: on QoS tab set CPU freq touchboost level 1 to 800 MHz (only the first slider). Then in Kernel Adiutor change CPU governor to Interactive. Set Max CPU speed to 1400. Go to advanced governor settings and set hispeed_freq to 400 MHz.
These settings are doing two things:
1. When not in use (e.g. you are not touching your phone), your device will use ONLY energy-efficient A7 cluster. So max 1300 MHz (it shows 650 MHz in Kernel Adiutor because A7 cluster is showing it's real freq divided by 2) with four cores - a performance level of middle-ground MTK device. Most often the phone will use 800 MHz freq of A7 (that's 400 MHz setting of hispeed_freq - a division by 2, remember)
2. When you are using device (actively tapping), touchboost will switch your device to A15 cores (starting from 800 MHz - at this freq they consume roughly same amount of energy as 1300 MHz'd A7) and if needed, interactive governor will ramp the freq even some more - up to 1400 MHz. When there will be no load, freq will drop to the minimum and system will switch to A7 cluster until next time you use it.
Extreme Power Saving profile: Disable touchboost, CPU governor is Interactive. At advanced governor settings set hispeed_freq to 400 MHz.
This makes your phone use ONLY energy-efficient A7 cluster no matter what circumstances. No matter what max CPU freq is set, interactive governor can't switch from A7 cluster to A15 (maybe that's a bug, but we'll use it). You can set max CPU speed to 650 MHz for sure, didn't make a difference for me.
Yes, it may lag. Yes, games are not playable. But we don't paint your screen black and white at least. Movies are fine, texting is fine, browsing too, 1300 MHz of A7 are still quite good - it's like low-end phone but with 3 GB RAM and AMOLED. Combine it with lollipop powersaving mode and GPU powersave bias (set in Synapse, always clocks GPU at 100 MHz). And your phone will go on and on and on...
Don't forget to click thanks button. Tell me your experience. My device is broken so there could be some mistakes. My apologizes. Have a nice day!
First. Thank u sir

Kernel Adiutor doesn't make profiles to share. You have to manually set parameters and then save profile for your device. That's only the guide of parameters to use for your needs.
Thanks for sharing.
I'm using TOS (a Chinese rom) now, and I got excellent battery life. The phone is still smooth.
If you're strict with battery life, TOS is really worth trying.

Based on Touch Wiz. In China google is blocked so there's no gapps.
The rom is already prerooted, you just need to open it in Manage(an app)-Permissons-Root access.
It's 905MB.
Now i'm using it everyday, it's quite stable and smooth. And games (e.g. Hearthstone) are playable.
I don't know how to install Xposed, it errors every time I want to flash it.
As for free ram, I don't know how to check it in this rom.
i want to know that if this kernel works on flyme rom

Most often the phone will use 800 MHz freq of A7 (that's 400 MHz setting of hispeed_freq - a division by 2, remember)
2. When you are using device (actively tapping), touchboost will switch your device to A15 cores (starting from 800 MHz - at this freq they consume roughly same amount of energy as 1300 MHz'd A7) and if needed, interactive governor will ramp the freq even some more - up to 1400 MHz. When there will be no load, freq will drop to the minimum and system will switch to A7 cluster until next time you use it.
Extreme Power Saving profile: Disable touchboost, CPU governor is Interactive. At advanced governor settings set hispeed_freq to 400 MHz.
This makes your phone use ONLY energy-efficient A7 cluster no matter what circumstances. No matter what max CPU freq is set, interactive governor can't switch from A7 cluster to A15 (maybe that's a bug, but we'll use it). You can set max CPU speed to 650 MHz for sure, didn't make a difference for me.
Yes, it may lag. Yes, games are not playable. But we don't paint your screen black and white at least. Movies are fine, texting is fine, browsing too, 1300 MHz of A7 are still quite good - it's like low-end phone but with 3 GB RAM and AMOLED. Combine it with lollipop powersaving mode and GPU powersave bias (set in Synapse, always clocks GPU at 100 MHz). And your phone will go on and on and on...
Don't forget to click thanks button. Tell me your experience. My device is broken so there could be some mistakes. My apologizes. Have a nice day!

Hello sir.... I am using sumax v3 karnel with the settings you have mentioned in the thread. Everything is fine... Battery life is great... No problem of heating... Speed is ok but i have facing a problem.... MY PHONE FREEZES RANDOMLY ANY SOLUTION PLEASE HELP. IT FREEZES WHEN SCREEN IS OFF AND I HAVE TO RESTART MY PHONE. I AM USING CYANOGENMOD 12.1. PROBLEM OCCURS ONLY WHEN I USE SUMMAX KARNEL AND PRESCRIBED SETTINGS.
set cpu gov ondemand because its hard to wake up cores on extreme low freq when on sleep mode

Tuning Battery Life on Samsung Note 3 N900
I don't have a device anymore, but I still wish to share my experience and how I achieved 6 hours SoT with my typical daily usage on this phone.
This guide is for CM12.1 / AICP 10.0 (I recommend latter, it's the same CM 12.1 but with more options).
You can try this settings on aurora/stock ROMs with respective custom kernel (Suemax).
First of all, you need a kernel with Synapse support. This section is for CM12.1/AICP only! Don't try to flash these kernels if you are on Aurora/Stock - you'll have bootloop!
-- Download Stock and DJMax81's V2 kernel from this post and Suemax kernel from this post.
-- Make a backup
-- Flash CM12.1-DJmax81-Kernel-Lite-V2.zip
-- Boot your phone once and open Camera app to ensure it works.
-- Reboot to recovery and flash CM12.1-SueMax-Kernel-V3-By-DJMAX81.zip dirty. No need to wipe cashes.
-- If you encounter issues, restore backup or flash CM12.1-Stock.zip to return to the stock CM12.1 kernel.
Now you can fine-tune your Exynos!
First, disable touchboost. It's some sort of cheating Samsung use to make it's touchwiz not so laggy. On stock Android you simply don't need it, even if you set max CPU to lowly 250 Mhz, Stock Android UX is still decently smooth.
How to do this: open Synapse, go to the QoS tab. There are many, many sliders to control boost in different situations. Slide every one of them to the left. Now you gave full control of your phone freq to the governor.
This setting alone gave me up to 1 hour of SoT when texting or browsing. Because these are not demanding tasks and there's no need for CPU freq to ramp up.
Second, set min GPU speed to 100 MHz. This will save some juice when idle. Go to GPU Control in settings and set the corresponding Min freq slider to 100 MHz, then apply (you need to push the Set GPU settings button and a tick at the right top). You can also adjust Max GPU freq to suit your gaming needs. The more max GPU speed, the better gaming perfomance will be and the worse battery life in games (600 MHz stock value).
Third, let's go to Kernel Adiutor and here are some profiles for you that I found best!
Max Performance profile: Use zzmoove governor, max CPU speed to 1900 MHz, and at advanced governor settings set disable_hotplugging to 1.
Exynos hotplugging has rather negative effect on battery life as I found from my tests, you should never use it. If you are reading this and on Stock/Aurora ROM: disable hotplugging. It makes your battery life worse! Here is the test on Snapdragon 801, on Exynos hotpluging would yield even worse results because CPU with less core active will spend more time on unefficient A15 cores.
Zzmoove is the smoothest and fastest governor I found that still uses all available frequencies wisely.
That's the profile one should use for heavy games (and also set max GPU speed to 720 MHz in Synapse if you need it).
Performance profile: Use Interactive governor and max CPU speed 1900 MHz.
Interactive governor proactively ramps CPU to high (but not highest freq) to ensure great smoothness and still yield not-that-bad battery life (I had usually 4 hours SoT with 2G). For better fine-tuning you can go to advanced governor settings and set hispeed_freq to something in the middle, 800 MHz for example (but not lower than 800). hispeed_freq setting is the intermediate cpu speed which governor uses when there's initial load on cpu.
Balanced profile: Change governor to Ondemand, max CPU speed is still 1900 MHz.
You shouldn't worry, with touchboost disabled it would rarely ramp up to max speed, most often sitting on energy-efficient A7 cores and sometimes ramping to 1200 of A15, going even higher only when needed - still gives you whole power of your device without restrictions. DJMax81 did great job tuning this governor to our needs. You still can set max CPU lower (to 1400 Mhz) if you wish to conserve battery more on this profile.
Power saving profile: Go to Synapse and enable a slight touchboost: on QoS tab set CPU freq touchboost level 1 to 800 MHz (only the first slider). Then in Kernel Adiutor change CPU governor to Interactive. Set Max CPU speed to 1400. Go to advanced governor settings and set hispeed_freq to 400 MHz.
These settings are doing two things:
1. When not in use (e.g. you are not touching your phone), your device will use ONLY energy-efficient A7 cluster. So max 1300 MHz (it shows 650 MHz in Kernel Adiutor because A7 cluster is showing it's real freq divided by 2) with four cores - a performance level of middle-ground MTK device. Most often the phone will use 800 MHz freq of A7 (that's 400 MHz setting of hispeed_freq - a division by 2, remember)
2. When you are using device (actively tapping), touchboost will switch your device to A15 cores (starting from 800 MHz - at this freq they consume roughly same amount of energy as 1300 MHz'd A7) and if needed, interactive governor will ramp the freq even some more - up to 1400 MHz. When there will be no load, freq will drop to the minimum and system will switch to A7 cluster until next time you use it.
Extreme Power Saving profile: Disable touchboost, CPU governor is Interactive. At advanced governor settings set hispeed_freq to 400 MHz.

Hello Where can I go to see the "Kernel Adiutor" whether I need to install it from PlayStore?

Sir i have been already using ondemand governor but problem priciest i reflashed the rom and usesed with stock karnel for 2 days phone didn't freeze with stok karnel but as i flashed the karnel and set the given values it started freezing again... I want to use the karnel because everything is better than the stock one heating issue is major one with the rom but can be solved by the karnel but how to get rid of freezing problem.

Try to increase voltage slightly, +25 mV should be fine. Kernel Adiutor - CPU Voltage - Global at right top. It will not make any effect to battery life. If I remember correctly, Suemax kernel is a bit undervolted by default and if on most phones it's fine, on some it can make issues.

You can install it from Play Store, if you don't have one. On my ROM it was just built-in. Synapse should be built-in in kernel, you can update it from Play Store as usual.

Sir i have set cpu voltage +25 the problem have been solved by doing so but some time cpu voltage automatically increased and phone start lagging and freezing... Any solution sir.. Thanks in advance.

Hmm, can you tell some more about this? I don't even have a clue, how the voltage can be increased automatically and phone start to lagging from more voltage? Usually, it's the contrary: more voltage = more stability for overclock etc.

Sir i set the cpu voltage by +25. Phone didn't freeze but after a day it freezed again when i checked the cpu voltage after restarting the phone it was the default values i set it by +25 again. After 7-8 hours some apps like Es file Explorer, Whats app, uc browser stopped working (saying like whats app is not responding) i was unable to move some content from phone to sd card. Other functions like settings, dialer etc. Was working. Phone didn't connect to pc. Neither restarted nor power off (restarting and shutting down.) after restarting the cpu voltage was more then the default values. See screenshots sir

Really strange. What ROM do you use? And build date.
