[Q] Is it possible to set CPU speed cap per app? - Galaxy S 4 Q&A, Help & Troubleshooting

Does anyone know if there is an app, or modified version of CyanogenMod's Performance Settings that allow users to cap the cpu speed per app?
I am asking this because when I play some old school games with RetroArch or running any other games, I know the application can run smoothly with, say 50% of the speed, however, the phone would go all the way up to the max speed and drain excessive battery over time (especially when we play games with it)
With the PAC Rom i was able to monitor the CPU cycles of the phone (didn't have this tracking feature on my old phone's CM). Here I've attached 2 screenshots to show you what I mean...
One of them I capped it at 1.3ghz, the other one is at stock max speed. Both running the same game for a little bit doing similar stuff.
I think if we can have per app CPU speed cap, we could potentially make the battery last longer.

Iconia A500 Full Benchmark "TESTING"

This thread is Meant to display my results from "battery" testing "performance" benchmarks etc. to show its fullest potential.
I've ran "quadrent, linepack and some other benchmark" results vary.
QUADRENT I usually get depending on how many widgets, background task are open about 1900-2300 and Used "SET CPU" To performance mode "926 MHZ - 1000 MHZ
Eagerly waiting on a OC For the tegra 2 chipset on the iconia "xoom" has already achieved great speeds of 1.5 (1500) GHZ
I made a short brief 6 minute video of me running a few benchmarks, to show the speeds it achieves. "video proccessing will be watchable in about 5 minutes"
http://www.youtube.com/watch?v=6CN2bZisCvg
Next test i will be running on this device is battery life, something lots of people are converned about should have results in qbout 48 Hours, will keep update will run many test on this device, from straight playing games battery life to just movies web browsing etc. the whole 9 yard.
Will continuasly post updates on new things i found out from overclocking testing everything you can imagine.
I also ask that we all as a community can share our expieriences with the device from batterly life to performance to enchancements.
"l3giticonia out"
Wow I wish you had kept this thred up I would have loved to see this before I purchased.
hmmmm
Correct me if I am wrong, please: but by using setCPU to set a "performance" option and setting the speed lower then stock clock speed (926 mhz?) you have now disabled the systems ability to lower the clock speed and are underclocking the system.
Am I mistaken in assuming that you are going to get rather useless data on the overall performance of the system by setting these options? By underclocking, you have installed a custom kernel on the device and any results you get are going to be subject to the performance of that kernel, which is not what the a500 stock is running.
Why 926 mhz? Stock is 1.0 ghz, I generally run at 1.4ghz+. Am I missing something? Again, by setting SetCPU to "performance" any data you come up with is going to be on a system that cannot lower clock speed during low use periods, so your battery life stats will be lower then a normal users experience.
ARM based chips are built to scale the speed depending on load. By setting performance mode, you disable the chipsets ability to scale, right?

[Q] CPU

ive just looked at a phone tester app thing, and found out my A500 is only running at 480mhz, how come? tried couple other apps to check and not moved, it should be an 1ghz?
help lol
Like virtually all modern processors, the CPU in the Acer scales its speed to the current required load; running @ 1GHz full time would generate additional heat (and system wear) as well as reduce the battery life.
My tab tends to spend about 2/3 of its time @ 456MHz and underMHz, and about 11% @ 1GHz, the rest being spent in between (with very few stops in the 760/816/912MHz stages.)
If you have SetCPU (requires Root) you can fire up a reasonably complex game for a couple of minutes and check the Time in State info again.
Now, if this isn't the case, what specific "phone tester" app did you try?
Yeah you would not want your tablet running Max CPU speeds all day.
Sent from my ADR6400L using XDA App
i understand about not running full all the time, but its a constant 430.39, it hasnt moved, even using a high end game or anything?
What's a high end game for you?
Because my tabled does go to 1GHz while playing Galaxy on Fire 2.
Get systempanel from the market and test.
If you are rooted, you can use the script i wrote to log clock speed and usage % of both cpu cores while you are doing something. I OC to 1.5 GHz and it is easy to crank both cores to to the max while watching a movie or even just browsing the web.

CPU never goes above 1.440 ghz

So I usually use CPUSpy to monitor my CPU usage. This comes in handy once the device is rooted and I can see how custom kernels and settings affect battery life and cpu cycles. My LG G4 is the tmobile variant and obviously not currently rooted. I notice through CPUSpy that my cpu speed literally never exceeds 1440mhz.
I don't have any problems with that per say, everything on the device still runs buttery smooth without anything more than the occasional hiccup or lag. I'm curious if anyone else has monitored their CPU speeds and noticed the same thing? I just find it a little interesting.
CPU spy can't even see the A57 cores so there's no way it can see what speed it's running at.
4 cores are limited to 1.44 the rest are 1.8
I have not used CPUSpy. But CPU-Z will show you the speed of each of the 6 cores. As mentioned, the last 2 are the only ones I've seen reach 1.8GHz, the first 4 seem to top out at 1.4 GHz.
Ok.. Using cpu-z..
That's how mine looks "at rest". When it's sitting quietly, saving the battery. Crank up some apps, and you should see those clock speeds rise.
But, trying to improve my battery life, and keep the temps down, I've been hoping to see those numbers stay low, not actually show how high they can go
I agree.. As ive stated, the device runs great i just found it odd. It even calls it a 1.44ghz cpu in the cpu profile and mostly no matter how hard i push the device i cant break that speed
Right as CPU-Z opens, the clock speeds spiked briefly. I was able to get a screenshot quickly.
Do yours also jump up for a second or two right as the app opens?
This has been discussed already. As the previous post shows, they do get to 1.8Ghz when required.

Is it safe to change my CPU governor to "performance" to force max clock speed?

Is it safe to change my CPU governor to "performance" to force max clock speed?
I don't want to overclock my Note 4, don't worry, not talking about that. But I am talking about MAX clocking it - forcing it to run at maximum rated speed. I've already tested out SetCPU and used it to change my governor to performance which forces the clock to max, and it nearly doubled my framerate in many games, especially the ones that struggled to play on this device like Xcom:EW.
But I quickly turned it off because I wasn't sure it was safe to do in the new era of smartphones, what with their DVFS and all. I'm worried that I'm going to overheat the CPU, and it's not going to be able to downclock because of temperature anymore. I'm only modifying the governor, but what if I actually used SetCPU to just change the CPU clock to max, without even touching the governor?
Can I hurt my phone by doing this? Can I safely start forcing my CPU to run faster while playing games, knowing that the only thing I risk is my battery draining faster, or am I actually risking damaging components by doing this?
Hello and thank you for using Q/A,
your CPU will not be damaged, but the battery life time will be shorted.

I personally have used Performance governor on Moto X 2013 for almost the whole 8 months I had it, 24x7 I mean. Never had a problem, yeah maybe battery life was little less than normal but I never did really care about it. Then I ran the same governor for a good period of time on my Note 3 too, same, no problem at all. Like you said, in games the frame rate difference is massive, but I don't play much games, I simply used that governor because it gets rid off all those micro lags and jitters which are Android's trademark, I simply can't them, with default Interactive the micro lags are very apparent.
However with Note 4 I am pretty happy with the BluActive governor, it makes most of the micro lags to go away, so sticking with it.
In any case unless you plan to use a mobile phone for maybe 5 years or so, I don't see any problem at all with it, other than a slightly increased heat, and maybe a little less battery backup, but you will find so many comments which might scare you, that chip burns off if you run it and all that, but those mainly are BS.

best battery rom

What is the best battery rom and your best SOT?
in my experience ; the best battery rom is eui 5.8.019s
I tested miui and battery was very correct in my opinion.
small eui v3 beta its good at the moment.

5-5.30. Gaming, social media etc
I am currently using Miui 10 pro global V8.9.20 + Illusion kernel V3 which is giving me 5:30 hrs of screen on time completely bugless.
You can get the Illusion kernel only in the Le 2 Telegram channel posting link for the same you go & download kernel from there.
1. Le 2 telegram channel link for Kernel
https://t.me/LeEco_Le2 (click this link in your phone after installing telegram make an account , use Chrome or Opera browser only other browser don't redirect this link).
2. Miui 10 pro Global for Le 2 link Gdrive
https://drive.google.com/file/d/1gbspIBvM3EhBeapluGfZl-UECNB_fEeQ/view
Cannot get illusion kernel.

I have never got this much screen on time on the leeco le 2 (SD version) so I just had to share this with somebody... anybody really. Whomever has done better please feel free to share your awesome le 2 battery life with smallEUI, stock,or any other rom (doubtful).
So I just got 8 hours and 30 minutes of sot running smallEUI version 3 with illusion kernel v2.5. (Note: I used v2.5 because v3 uses lazy plug for CPU hot plugging which IMHO has far more battery drain than the stock Qualcomm core control) but I digress...
Anyways, I am a heavy gamer and frequently play real racing 3 for more than 1.5 hours in some days Today I decided to cut back and only played it for 25 minutes.This reduced gaming time enabled me to subject my phone to a more mixed use pattern. When I started I wasn't even looking to break any screen on time records but at around 21% battery remaining, I was at 7 hours SOT so I decided to keep using the phone normally until I ran it down to empty.
Here's some background to this achievement...
First off, I don't run anything on stock settings. I use a slimmed down EUI rom, a custom kernel to boot, and minor tweaks to the build.prop. I have done major tweaks to the custom kernel, use greenify in elevated mode, and block the recommended wakelocks on kernel adiutor app. I have also improved thermal thresholds to minimize throttling. When CPU thermal throttles, it leads to more power consumption because it has to stay on longer and use more CPU cycles to finish tasks that it could have completed much faster with high clock speed at the expense of negligible heating. I looked at the stock smallEUI thermal config and was shocked to find that the CPU starts throttling when it reaches temperatures as low as 38 degrees Celsius. (That's too low). The big cores are allowed to hot plug at a measly 40 degrees and at 42 degrees the system is allowed to turn off three of them. Only CPU 4, which is the first big core that controls the other 3 is exempted from being turned off due to this insanely low threshold. However, it doesn't escape the overall thermal tolerance which is set at 38-70 degrees. At which point, it will be doing just 883MHz before getting completely shut down! We all know (I hope we do) that big cores are generally more efficient at higher clock speed but someone must have missed the memo here. (Big cores are set to throttle down to 998MHz at just 50 degrees! Crazy, right). @iaureeel should look into this.
For monitoring, I use better battery stats xda edition, gsam battery monitor, and kernel adiutor overview page. I don't have WiFi so all data comes through 4G (the signal is usually above average to excellent) -- this phone has better reception than any other I've ever used ??
The usage:
Here's a summary of the notable things I did. You may browse the screenshots to see more.
First off: Games...
I played real racing 3 for around 25 minutes
Tried out a newly downloaded (on this same charge cycle) 3D game called war wings -- Around 20 minutes. Spoiler alert: it's awesome?
Starting with full charge and hammering the battery to about 15%, I can play real racing 3 for 4 hours non-stop.
Others:
I watched some YouTube over 4G for 30 minutes
I used brave to browse the web for just over an hour.
Side note: surface flinger showed up on BBS probably because I speeded up scrolling in build.prop. It shouldn't be this active but the power draw is probably not too significant.
How I did it
Recap of what enabled me to have this sot figure:
1. Optimized custom EUI-based ROM (smallEUI)
2. Custom kernel (heavily customizable and tweaked to kingdom come)
3. Greenify
4. Higher thermal tolerance for the CPU (it doesn't even get hot enough to be uncomfortable even at highest load. The plus for the battery here is that the CPU completes tasks much faster and then goes into a quick race to idle (thanks to a tweak I've added to blu_active governor for big cores)
5. No automatic brightness! I often get by with minimum brightness but when I need more I manually bump it up to 10-25%. 50 % is enough for me to comfortably use the phone outside. And not in direct sunlight because who can compete with the sun? Not any phone's display. THAT'S FOR SURE!
6. Cherry-picked build.prop tweaks
7. No Facebook, Instagram, Snapchat, and other naughty social apps that put your phone in a wakelock chockhold until its precious juice is depleted.
Conclusion:
I have never been one to hunt screen-on-time records (and wasn't in this case) but today has showed me a side of this phone that I didn't know existed. That's really good battery backup. I didn't think it was this easy but leeco did some clever things too in order to make it possible. First is charging the battery to 4.4 volts which increases charge holding capacity to 110% of the reference design. I don't recommend that you charge to 100% because it will be at the expense of battery life span. (Unless leeco uses a military grade battery like they do in the Coolpad cool 1 dual and LeRee le 3).
Another thing that helps is the inclination of EUI towards power saving. SmallEUI is even better because it saves power without hindering user experience. Notifications come on time and there is no stuttering even on stock everything.
Full disclosure: My phone is brand new(ish) at just one month old.
That's all for now... Check out the screenshots. As they say, the proof is in the pudding ?. There's a limit to the number of files I can attach so I've put the rest in a .zip file

For monitoring, I use better battery stats xda edition, gsam battery monitor, and kernel adiutor overview page. I don't have WiFi so all data comes through 4G (the signal is usually above average to excellent) -- this phone has better reception than any other I've ever used ??
The usage:
Here's a summary of the notable things I did. You may browse the screenshots to see more.
First off: Games...
I played real racing 3 for around 25 minutes
Tried out a newly downloaded (on this same charge cycle) 3D game called war wings -- Around 20 minutes. Spoiler alert: it's awesome?
Starting with full charge and hammering the battery to about 15%, I can play real racing 3 for 4 hours non-stop.
Others:
I watched some YouTube over 4G for 30 minutes
I used brave to browse the web for just over an hour.
Side note: surface flinger showed up on BBS probably because I speeded up scrolling in build.prop. It shouldn't be this active but the power draw is probably not too significant.
How I did it
Recap of what enabled me to have this sot figure:
1. Optimized custom EUI-based ROM (smallEUI)
2. Custom kernel (heavily customizable and tweaked to kingdom come)
3. Greenify
4. Higher thermal tolerance for the CPU (it doesn't even get hot enough to be uncomfortable even at highest load. The plus for the battery here is that the CPU completes tasks much faster and then goes into a quick race to idle (thanks to a tweak I've added to blu_active governor for big cores)
5. No automatic brightness! I often get by with minimum brightness but when I need more I manually bump it up to 10-25%. 50 % is enough for me to comfortably use the phone outside. And not in direct sunlight because who can compete with the sun? Not any phone's display. THAT'S FOR SURE!
6. Cherry-picked build.prop tweaks
7. No Facebook, Instagram, Snapchat, and other naughty social apps that put your phone in a wakelock chockhold until its precious juice is depleted.
Conclusion:
I have never been one to hunt screen-on-time records (and wasn't in this case) but today has showed me a side of this phone that I didn't know existed. That's really good battery backup. I didn't think it was this easy but leeco did some clever things too in order to make it possible. First is charging the battery to 4.4 volts which increases charge holding capacity to 110% of the reference design. I don't recommend that you charge to 100% because it will be at the expense of battery life span. (Unless leeco uses a military grade battery like they do in the Coolpad cool 1 dual and LeRee le 3).
Another thing that helps is the inclination of EUI towards power saving. SmallEUI is even better because it saves power without hindering user experience. Notifications come on time and there is no stuttering even on stock everything.
Full disclosure: My phone is brand new(ish) at just one month old.
That's all for now... Check out the screenshots. As they say, the proof is in the pudding ?. There's a limit to the number of files I can attach so I've put the rest in a .zip file

I have THE Answering for You and ALL other Le Membershipper`s...
If you have a Smartphone, You have to CHANGE your Battery between 12 to 18 Month`s. If you are working in Office and you Use the whole Day Wireless Lan? Then, you have to change the Battery between 12 Month`s and every Year behing the change!
And Dubble 3M Band for the Displayframe you have to Buy also. Oh, IF, you want to Change your Battery then you NEED a HOT Gun Pistol with Minimum 110 Degrees! Heat Up the Frameside about 5-10 Millimeters and DON`T Lift it UP in the Roundings of the Edges! They are Breaking!!
