SetCPU vs. CMSettings Built-in CPU manager

For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?

I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.

I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.

Neither. CPU tuner works best for me.

its the same thing :facepalm:
Try the inbuilt one... I think its way easier

I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?

Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.

I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).

At 1.8Ghz, I find the temp settings in SetCPU very useful.

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...

Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.

SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.

I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?

im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.

KitKat possible Lag Fix

Note: Root IS required!
1.) Install No-frills CPU Control.
https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
2.) Open the app and set Governor to msm-dcvs
3.) Check "Apply on boot"
4.) Click "Apply" then "Exit"
5.) Reboot and test performance.
I notice a huge speed improvement and also music playback does not stutter anymore also. I am not sure how this will affect battery life. Enjoy!
Update: Music still stutters and garbles. Blah! Atleast performance is good!

This is no real governor, it's sort of a Qualcomm "testing" governor, which u shouldn't use.

You are correct. I am seeing better performance because the CPU is being locked at 1.5Ghz.
Do NOT use this!! It will drain your battery! Admin, please close this thread!

if the CPU is locked at 1,5ghz, then why does the explanation for MSM DCVS say
a very efficient and wide range of Dynamic Clock and
Voltage Scaling (DCVS) which addresses usage models from
active standby to mid and high level processing requirements.
A Krait CPU can smoothly scale from low power, low
leakage mode to blazingly fast performance.
Believe it's a governor that is mfg'd by qualcomm to utilize new on chip features.
MSM is the prefix for the SOC (MSM8960) and DCVS is Dynamic Clock and Voltage Scaling. Makes sense, MSM-DCVS

Yesterday i saw this topic and set my governor to ondemand. Till then there is no lag or dropout music play via bluetooth headset. Probably there is some miss configuration on default interactive governor.

[Guide] Get rid of lag in games / Interactive gov is bugged!

Hi guys,
I have the 855 version of this phone, and I have noticed that, even if Antutu scores are spot on (44k), in games such as GT racing 2 or similar I get a lot of lag.
Now, everyone will think "there are 1000 threads about lag, stick to those". Unfortunately, tricks such as getting rid of the thermal protection are really not good options, as the phone temperature will start to skyrocket.
There's a much easier and safer solution: root the phone and change the governor from interactive to conservative.
With interactive gov and CPU temp open in the background, I have noticed the CPU frequency bounces continuously up and down between 300mhz and 2400, even if the CPU temp is only 55c or so. This is causing the lag! Interactive governor is severely bugged, and this happens with any rom (I have tried both the stock 20h and the ChupaChups 4.2) and kernel (non AOSP at least).
Then, I switched to conservative, launched the game again, and guess what....now the frequency is nicely stable at 2457mhz throughout the entire gameplay and lag is gone completely. Temperatures? Totally fine: max 60c while playing and usually between 35 and 40 while whatsapping.
I literally tried everything to get rid of this damn lag, and the only thing that worked before this solution was to use a different kernel (chupa chups 2.1) and changing the governor...but I was getting crazy high temperatures, that sometimes touched 80c, and this was with a very heavy undervolt too! So I recommend to use the stock kernel, because it's the only one - for me at least - that grants good performances (and by that I mean no lag in games whatsoever and constant 2450mhz while playing) with good temperatures.
Any other option, including undervolting and trying different kernels didn't work for me, because either the CPU frequency kept shifting up and down every second causing lag, or - when I managed to keep it stable using different kernels and undervolting - the CPU temperature while playing got way too high (70c+, touching 80c sometimes).
To sum it up
1) Stick to stock rom and stock kernel (because of temperature issues)
2) Root
3) Change governor from interactive to conservative with Trickstermod (busybox required)
4) Enjoy smooth gaming experience and very good temperatures, with no significant throttle whatsoever!
Hope this helps!

as far as i know, conservative puts the cpu speed into the lowest possible, thus i thought won't be good for gaming performance.
nevertheless, i'd try for a few days and see if there's any noticeable difference.
thanks for sharing the knowledge, OP!

Theoretically you are right. But...interactive is bugged. Ondemand doesn't work (it will make your phone freeze) and performance will drain too much battery. So we are pretty much left with conservative.
Give it a try, and when you do, make sure you have CPU temp open to monitor both temperature and cpu frequency!
Let me know

Thank you! It really did the trick, gaming became MUCH better.
I tried RR3 - it became a lot better. On interactive it lags even in menu, on conservative it's rendering at 23-30 fps with slight not-game-breaking lags.

Battery
And about the battery? Will drain more in conservative than interactive? And will speed up the phone in all app or only in heavy games, when cpu is more active?

I wouldn't worry about battery life..

It seems that this working generally, phone is much snappier and smooth for me than on interactive.

Yeah...the reason is that LG did an awful job with the interactive governor, and what's even worse is that it's actually using it as the default one.
Pretty incredible how bugged this is.

Yes but I think it's possible to make script in init.d folder to run conservative on boot as default. Maybe someone make one.

I Will try this ☺only for curiosity! I need busybox installed too or trickstermod only?

I've been doing the same thing for a long time now. I use SetCPU to automatically switch to the performance governor whenever the screen is on, and interactive whenever the screen is off.
You may also want to consider disabling mpdecision and thermald also. One of the two (probably mpdecision) will regularly change the governor back to interactive if you don't.

That works to get rid of the lag...but my phone was reaching easily 80c.
Now, with everything stock, the frequency stays nicely at 2457mhz with no throttle at all and the in-game temperature only maxes out at 63/64c.

Thanks for sharing this brother...just switched to conservative in trickster and I'll see how it goes.
I'm on crash Rom stock kernel with thermal mod activated...
Don't have any temperature issues till now expert while playing heavy games for some time.
Thanks again

Are the settings in trickstermod applied as you change the setting ? Or do you need to apply them manually ?
Also, do they apply on boot ?

I will try that, thx for the info.
Now how i can put it to change on boot?

On the latest trickster version you hit the upper right settings icon and the first four option that appear are under the set on boot part.check the kernel setting to be set on boot and you are done.

[GUIDE] Tweaking Interacting Gov

Hey guys, Kyuubi10 back once again with another Guide.
I thought it might be useful to pop in a couple results of my trial and error for the HTC One M8.
Note: This is not scientifically, calculated accurate, but it's close enough, based on estimates.
After following these guides:
http://forum.xda-developers.com/showthread.php?t=2769899
https://vjnaik.wordpress.com/2015/06/25/kernel-tweak-interactive-governor-paramaters-rooted-phone/
I decided to make a summary guide of the above but with specific HTC One M8 values.
Since I agree with the idea of "race to idle" embodied in the Wheatley governor, I tried emulating that on the Interactive governor while also keeping it as efficient as possible.
Here are the values (all others not mentioned, leave default):
Code:
[B]above_hispeed_delay [/B]- 80000 2265600:10000
[B]go_hispeed_load[/B] - 95
[B]hispeed_freq[/B] - 1728000
[B]io_is_busy[/B] - 1
[B]min_sample_time[/B] - 10000
[B]target_loads[/B] - 45 729000:80 883200:50 1267000:85 1497600:50 1728000:90 1958400:50
[B]timer_rate[/B] - 10000
[B]timer_slack[/B] - 5000
"above_hispeed_delay" makes sure that longer time is spent on the frequency step 1.72Ghz, before quickly raising higher into max freq.
1.72Ghz is the most energy efficient frequency with a good performance, e.g. it will not cause lag during casual usage, while it uses minimal voltage.
If the load is too high for this frequency to handle, I set the time short once it's gone over this freq step so that it will not waste time before reaching max freq. Thus dealing with the issue asap.
Another important parameter is "target_load", with this I have defined that at each efficient freq step the load needed to overcome it would be higher than normal. But it would up-scale quickly when using non-efficient frequencies.
The other parameters I have set so that the frequency is lowered as soon as CPU load is finished, so that it will rush back to idle as quickly as possible.
The interesting thing about this set-up is that for general, non heavy usage, it basecally functions as if I have underclocked to 1.72Ghz, but when the CPU is truly pushed it reaches up to 2.5Ghz which is my Overclocked max freq value.
Thus both saving battery and providing high performance.
I have felt no lag, and it's been quite a smooth experience while I used this
Combined with using GPU rendering (found in developer settings), and Seeder, the over all usage is pretty good.
Battery usage has been very efficient and I have managed to squeeze out an extra hour or two using this.
I highly recommend it!
Hope I helped you guys... don't forget to press the thanks button if you also feel that I did!:good::good:

I noticed I have some governor settings left at 0 or blank. I did some quick googling, found some other tweaks for the M8 and the interactive governor. So I played around a bit, and I think the following would be useful to add to the above tweaks.
-----------------------
sampling_down_factor: 60000
sync_freq: 1036800
up_threshold_any_cpu_load: 65
up_threshold_any_cpu_freq: 1190400
boost: 0
boostpulse_duration: 80000
--------------------
Also of note there is not a entry for " io_is_busy " under the Interactive governor under ElementalX Sense kernel v6.03. I believe it's possible to modify the governor to add the function, if it's desired.
Hope this helps others.

nice one i read the links that you posted and follow the guides there also to tweak the interactive governor on the first link that you posted is really interesting he has updated that post also, i followed his guide inspired by your guide and i have been getting good results on my phone with battery and performance i mean almost no battery drain at all while my phone is idle. thanks for the help mate!

Plugged the settings into Yankactive on DU. Quick, freqs stay low when nothings going on, seems legit. I set my timer_rate higher tho, 10000 feels a little low, makes me think that the CPU will spend too much time polling loads.

Some of those actually make no difference. Since they are overruled by other perameters. E.g. up_threshold aren't used in interactive, since they follow target_load instead.
Sampling_down_factor on the other hand is overrulled by the timer features of interactive.
When you use ondemand, or conservative, sampling_down_factor is a fun parameter to play with, but not interactive.
While Sync_Freq I don't like using because it raises minimum frequency to its value...although temporarily, the timer features can already deal with CPU loads efficiently.

That's the idea. And never heard of Yankactive...but I'm gonna assume it's good lol.
And about time_rate, you are right, but you are also wrong.
There isn't a true right answer unless someone performs a scientific experiment in order to fully test which one is better.
But I'll explain why I put my one short... I want the frequencies returning to IDLE asap. While yes, you are right it's polling often, it also returns to idle much faster, rather than staying at higher frequency uselessly wasting battery.
I'll try to run some tests checking CPU load, if CPU load considerable lowers I'll come back and report.

Yankactive is Interactive with some under the hood tweaks, I believe, same tunables. I also looked at some documentation on Interactive and I think the target_loads have to be in ascending order based on load when paired with clock speeds, I'm gonna mess with them a bit and see what I get. Link

And no, target_loads has to be in ascending order based on FREQUENCY. You are applying load percentages to frequency ranges, therefore it is imperative that its the frequency defining the order.
e.g. 50 4:80 10:20 12: 50 means:
50% load before going to the next frequency step, until you reach frequency 4, then use 80% instead until frequency 10, then use 20% instead until 12, then use 50% until max frequency.
Feel free to play with them as much as you want, just make sure to keep the idea of using efficient frequency steps in mind.

You had performance on?? You do realise that the perf gov basically keeps your CPU cores running on max frequency all the time right?
No wonder your battery was dying XD
Anyhoo....good thing you found my guide
Now, about multicore power savings, as usually with most things you will be compromising something to gain something else...always keep that in mind.
With MPS you'll be giving up some multitasking, in order to gain some battery savings.
Why (you may ask)?
Well, think about a to-do list, and for each list you have one person completing the tasks within that list. Let's say you have four lists and 4 people completing those tasks.
What MPS does is it takes as many tasks as possible and places them within a single list, for one person to do. At the end of the day that one person will have done a lot of work, while the other 3 will have done very little work. The drawback? The work was completed much slower, because only one person was doing it.
Why can MPS be good? It is the way it chooses which CPU to use to add the tasks to, it chooses CPUs which are already turned on, rather than turning a new one on.
The frequency voltages on each core range from the lowest of 775mV, to the highest of 1075mV. That's a 300mV increase in battery consumption between lowest frequency and highest. (Mind you, 1075 for me is an overclocked value, if you are not OC then it will be even less)
When CPU cores have nothing to do they get turned off....they don't idle at 775mV....they are literally off. Therefore around 0mV usage XD
If you get tasks which would have run on 2 CPUs at minimum frequency, using only 775mV each, and put them to run on only 1 CPU at MAX frequency at 1075mV, you still have about 400mV battery savings. Now lets say its something which would have used 4 CPUs, but you end up using only two.... then the battery savings double to 800mV.
Final answer...it depends on your tastes, what do you prefer most? Multitasking or battery saving.
Personally I keep it enabled, but not aggressive.
But if you really don't care about multitasking, you may as well leave it as aggressive.

Hello kyuubi10 thanks for your help, would it be ok to change mp decision to battery saver mode ? Whats your take on that?

It's in the ex app mate, it uses a less aggressive version of mpdecision to saver on battery power but I can't say that I noticed much improvement TBH.

Well, I use adiutor, so I don't have that option.
I am happy with my phone how it is (if it wasn't for the damned plug issues XD)
But @lil_kujo, as @smeejaytee said....he hasn't noticed much improvement.
So I'd trust his advice

You had performance on?? You do realise that the perf gov basically keeps your CPU cores running on max frequency all the time right?
No wonder your battery was dying XD
Anyhoo....good thing you found my guide
Now, about multicore power savings, as usually with most things you will be compromising something to gain something else...always keep that in mind.
With MPS you'll be giving up some multitasking, in order to gain some battery savings.
Why (you may ask)?
Well, think about a to-do list, and for each list you have one person completing the tasks within that list. Let's say you have four lists and 4 people completing those tasks.
What MPS does is it takes as many tasks as possible and places them within a single list, for one person to do. At the end of the day that one person will have done a lot of work, while the other 3 will have done very little work. The drawback? The work was completed much slower, because only one person was doing it.
Why can MPS be good? It is the way it chooses which CPU to use to add the tasks to, it chooses CPUs which are already turned on, rather than turning a new one on.
The frequency voltages on each core range from the lowest of 775mV, to the highest of 1075mV. That's a 300mV increase in battery consumption between lowest frequency and highest. (Mind you, 1075 for me is an overclocked value, if you are not OC then it will be even less)

Hah, thanks for the guide-- I am pretty well versed in task / resource allocation on multi-threaded systems, though
Main reason I was asking was because I haven't a clue what some of the values are on this interactive gov. Just wanted to make sure they didn't clash! I'll chance it to "Enabled" rather than "Aggressive," because a compromise between the two sounds the best
As for Performance gov-- default setting on this flarport kernel, didn't bother to check it until I noticed that any time a core was on, it was racing at 2.5ghz, even with nothing going on. Battery pretty much committed suicide

LOL I suggest you change kernel asap! If the dev uses uses Performcance gov as his default he doesn't know what he is doing XD
And no, as far as I know governor tunables won't ever clash with MPS.

Thanks!

Hi mate, I wondered if I could ask your advice, I want to set interactive up on my maw Android TV box it's quad 1.5gb and I want maximum performance as its constantly plugged in, there is no battery so that's not an issue,
Sorry if you think this OT but I thought I'd ask you as you know the governor well, thank you in advance mate.

Speed and Battery tweaks.

So I've been following this section for months and just got my a2017u 2 weeks ago. I'm rooted with tenfars tool still locked on b20. I've noticed in the last few weeks a tapering off of new and useful info for this phone and would really like to see what and where everyone is with it? LSpeed? Kernel Auditor? Or any tweaks that have helped either performance or battery life!!! Looking for anything to make this already great phone better!!! TIA

I have been using EX Kernel manager to tweak the settings as kernel auditor was not working properly with the big.LITTLE arrangement. I have upped the readahead value and underclocked the cpu to 1036mhz on the little cores and 1401 mhz on the big cores. working still as snappy and getting +2h SOT. I'm a heavy gamer and Asphalt 8 still plays as fluid as before, even better tbh due to less heating.
If you don't like to underclock, you could try these:

+2h? That's really good! I know overclocking can/could/might damage the CPU. Does underclocking have any of the same risks? I'm rooted and unlocked atm. So no warrenty anyway

Overclocking can't really harm anything. The excess heat might but it would take a long time and really high temps (you couldn't keep the device in your hands). The only thing you risk by overclocking is a system crash. Just reboot, lower the clock values and voilà ! So no, underclocking can't hurt anything. Overvolting however poses a real threat to the integrity of the components. It's quite the same thing as in computers (except for the heat, you don't always realize it's too hot in a computer).
That being said, is overclocking still even possible on smartphones nowadays ? Just for the fun of it because it's not needed in the least on the Axon 7 .
That's impressive results ! Not sure those hours are needed since the battery is doing well with the software power saver but still a good thing to know.

Still any extra sot is welcome. I'm not a gamer, don't really have any apps that truly need the full power of the sd820 so might give it a shot. Greenify does wonders for standby time.
Not sure if the built in 'intelligent country control' does anything tbh

I'm on my phone most of the day whether it be YouTube play music, texts,calls,etc.. I'm just hoping to find a balance between battery and my multitasking ADHD LOL

Mine keeps switching back to 'normal' modes with CPU full on. Any idea how to fix that?

Yup, I had that problem too initially.
First, I made system changes persistent upon reboot by running this command in Terminal emulator(you can also use adb shell):
reboot disemmcwp
Secondly, you have to disable smart power in the quick toggles.
Once this is done, set your new max values, select the arrow next to it to make it applied on every boot and then reboot your device. It should work.
Note: Everytime you open the EX Kernel manager you will see the speeds jump to max for like 1 sec but if you actually check the cpu statistics you'll see that your settings are sticking and the max clock speed was just for everytime you open the app.

The smart power! I forgot that thing controls the CPU.
So that round arrow thing means apply on boot? I selected that, figured it meant something like that.
Cheers!
