High clock speeds with every governor? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi, I'm in the process of attempting to maximize my phone's battery life in every way possible. But my s4 likes to run at max frequencies when in chrome, flipboard, calculator, text messaging, etc. Even if it's the only app open it still runs at 1.89ghz. I have set the max frequency to 1ghz and it runs fine with no lag. I have downloaded rom tool box pro and set profiles for max speed when screen off/on etc. But is there anyway to force the phone to use intermittent frequencies? Or i can set certain apps to run at a higher clock rate, like games? I'm using chronic kernel and Dirty Unicorn 3.9.

download and flash Ktoon kernel. You can then use the KTweaker app to customize your clock speeds for different situations. If you look in the thread they list the settings that provide maximum battery.
http://forum.xda-developers.com/showthread.php?t=2292341

You can also use Tasker to accomplish this on an app by app basis.

I've tried Ktoonz before but I've had weird battery drain issues with it, so i stopped using it. With ktoonz my phone would drain 5-6% an hour when idling with just data on. But i'll give ktoonz another go. I'll try using tasker as well thanks for the suggestions.
Edit: I fixed the crashing, i think the performance controller from chronic kernel was conflicting with the cpu controller from ktoonz, since when i disabled it it worked fine.

[Q] SetCPU causes phone to freeze when used to underclock when screen is off

So no matter what kernel I use, when ever i use SetCpu (or overclock widget) to underclock my phone when the screen is off it causes the phone to freeze and I have to pull the battery out. I set it so that it goes down to 200mhz, tried 400mhz and experienced the same problem. Any ideas? Solutions?

More info.. What rom are you running? Are you sure your rooted? What settings are you applying?
I have not had any issues yet with setcpu and my screen being off

I'm running Baked Snack 1.1, doesn't matter what rom or kernel I use though, it still happens.
It doesn't matter if I use overclock widget or SetCpu, if I were to set it so that my phone underclocks to 200mhz or 400mhz while the screen is off it freezes and I have to pull the battery.
Same here im running stock and i've tried setcpu and no matter what i hav to pull the battery out everytime. So i uninstalled it.

I had the same problem set the cpu with min of 400 and max off 800 should fix your problem

It means that there is not enough voltage run that frequency on your phone. Some times these kernel developers undervolt the phone which all phone don't support at all. Try some other kernel like the xtreme kernel. That kernel actually work for me and I can underclock my phone without freezing.

wow.. i just posted something like this i had set cpu installed since i rooted my phone last week. today i was playing with the settings because my music was stuttering.. i thought it might be a underclockign problem so i changed the profile to "ondemand" it made the stuttering better and everything seemed fine. about 12 hours later i got home and was playing with the phone. i updated 3 programs in market and all of a sudden my phone would go to sleep and not wake up. had to do a battery pull. i uninstalled the 3 programs i updated but the problem kept going. just uninstalled setcpu. hopefully it resolves everything

The use of profiles is not recommended on Galaxy S phones. The developer of SetCPU actually does not recommend using any other governor than conservative, even though we've been able to make Interactive work on some kernels.
I'm running Baked Snack 1.3 and found it to be stable at 1.2ghz using OC Widget. With screen on I have it set to min 400 and max 1200. With screen off it's set to min 400 max 600.
I too am having this problem. No mater what rom or kernal I use. It seems as if Setcpu and Overclock widget sometimes cant read the frequencies and let the phone underclock to 19.2Mhz which is probably like trying to wake the dead!
I wonder if it has anything to do with the new Superuser.apk? it always seems like setcpu is trying to get permissions. Maybe, I dont really know. Can one of you really smart people look into this?
In the meantime the only profile that I have set is screen off Max 800 Min 400, maybe that will work?
same issues here. i'm running with my screen off at min 100 and a max of 800. If i change my max to anything lower, my phone won't wake up. I'm running the latest VIPERrom. I'm hearing some mixed feedback about this app so i would like hear your feedback.
What i've gathered over the last several months, is that SetCPU profiles are buggy with our phone. Its recommended not to use profiles.
I'm fairly certain that SetCPU should not be used without a custom kernel that allows for over/under clocking. If you're on the latest ViperROM then you are using a kernel that we have no source code for, therefore it doesn't support over/under clocking; rendering SetCPU useless and prone to cause problems.

My SetCPU is using conservative and I haven't had any problems so far. I am running BonsaiROM 1.14.

If you have it set to under 200 with the screen off it won't wake up after a while.
I've had the same problem on all builds and ROMs that I've used. The only constant through all the different setups I've used were Advanced Task Killer and SetCPU. I stopped using ATK (with auto-kill on screen off, I use EStaskmanager for manual killing when phone is on) and the problem seems to be mostly fixed. It does still happen once in a blue moon though, say once every day or two.
Phoenix Kernel/Syndicate ROM 2.1
SetCPU: 100min/1200max
Screen off: 100min/200max
Batter < 30%: 100min/600max

Cyanogen 7.0.0 lag when turning screen on

Just as the title says, but here's some more details.
I have my cpu set to 1.1Ghz during the normal day 245Mhz min.
I have my widget on my homescreen and a custom profile set for when the screen is off for 368max and 245min.
When I turn my screen on and unlock it, it lags on my screen and says 368 max, then it jumps to the 1.1 and everything is fine.
It seems to lag there longer than it used to, has anyone else noticed this problem.
I used to have Pershoots Kernel on 6.1, do you think if I put Pershoots Kernel back on it will eliminate the lag and switch to 1.1 faster than it does now?
Just some thoughts and advise would be great, thanks guys.

I would ditch setCPU and use CM's built in overclocking settings. set your clock speed to whatever you like and use the ondemand governor.
your screen wake lag will almost certainly disappear and I bet your battery life doesn't change a bit. you can play around with it, of course, and find what's best, but I have found that since CM introduced built-in overclocking, it is more functional to use it instead of setCPU. my battery life hasn't changed a bit, partly because when the phone is in an idle state it is underclocked by default, and also because I don't have setCPU constantly having to think to make changes to my clock speeds and governors based on what profiles I've set up.

[Q] Nexus 7 CPU running high

I tried to search for a thread relating to this but couldn't find anything, if anyone knows of one a link would be appreciated.
OK, so I flashed Motleys kernel 2 days ago. Everything was running fine, I had it OC'd to 1.6 and it was super fast and smooth. I had set the governor to "on-demand" to try and save some battery life(over "performance"), and also because it seemed like the CPU would run at full 1.6 constantly if it was set to performance (I don't know if that's how it should be or not, but this isn't the issue). I used System Tuner to OC it like he recommended in his thread.
Yesterday I set it to performance to run some benchmarks, and then continued using it on performance to see how it felt. About an hour and a half later I also started messing with my home screen and apps and ended up accidentally using Quick Boot to take me to the bootloader. After powering it back on I checked System Tuner to set the governor and once I did I noticed, according to System Tuner, that 2-4 of the cores are running at full 1.6 and the CPU usage is from 25%-100% even though I have nothing open.
I flashed my recovery via Clockworkmod Recovery, Motleys kernel is now replaced by the stock kernel, however I'm still having the same issue, but just at 1.3. Any idea why the CPU is running so high, for apparently no reason?
.....
OK, so I just checked System Tuner again and the CPU doesn't seem to be doing as bad now, but it's still all over the place and I don't have anything else open. Here are the times:
Offline - 77%
340MHz -11%
475Mhz 1%
1.2Ghz - 5%
1.3Ghz - 1%
Compared to yesterday when it had said 1.3GHz 79% or something like that (and was running nothing but system tuner).
So, yeah, that does seem a lot better but one thing remains; the CPU usage still jumps up to almost 50% and once again, I am running nothing but System Tuner, so something still doesn't feel right.
I think ondemand governor is causing the CPU to shoot up so often and quickly.(That's all I can think of.) I always use interactive and it's usually the preferred governor. Ondemand is more for people who play lots of games and they need the extra boost. If you game a lot then I guess you should still to it.

JFLTEUSC Lollipop Kernel Question

Hello
I have a jflteusc (US Cellular Galaxy S4) and have been running Vanir's 5.0.2.022815 build.
Running great so far, I have one major issue though. The CPU Governor is running in PERFORMANCE mode for each multi-cpu. This results in #1 the phone running very hot while doing most tasks, and #2 the battery draining pretty quickly. Over the last three days, I have run out of battery each day with minor usage within about 10 hours.
Today, just for fun, I used the app "3C Toolbox Pro" to set the Governor to INTERACTIVE for the main setting and each CPU. Granted, these settings do not save if I reboot my phone. Today I had a normal 11ish hour work day, used my phone an average amount (a few calls, some texts, some wifi and data browsing, email, weather and other apps were running in the background), and when I left work I still had 82% battery left.
Does anyone know of a Kernel that works with the JFLTEUSC on Lollipop/Vanir that does not run in such a battery intensive mode? I use to use apps like SETCPU and 3CToolbox Pro to manage governors on other phones, but both don't work well (save settings) with Multi-CPU phones.
Thanks
Don't kernels like Googy-Max, Alucard or Ktoonsez work on this model or rom?
If anyone could confirm this, that would be great. I have been using Trickstermod to force the governor to run Interactive, which tremendously increased my battery life
If no one else knows, then I don't see any other option other than trying yourself...
Just do a backup before.
Ktoonsez has only TW 5.0 Kernel.
The other 2 have AOSP, TW and GE 5.0 kernels.
Took the plunge and installed the latest Alucard for 5.0
Working fine so far, will reference that thread for specific info
Thanks

[Q] [CPU/GPU Governor] Best fitting for my needs? well described

Hello
I am on a quest to find the best governor or kernel for me.
Firstly heres my ''specs'':
I am using I9505, on GE JFLTE-GPE 5.0.1 rom. Right now i have Hulk Kernel, but i have also tried Alucard/Goggy_Max.
I do not care if i have to flash kernels, etc. but i do not wish to change rom
I use my phone for Facebook, Snapchat, Messenger, Chrome, Gmail and loads of music. My music is on my MicroSD (64GB 95MB/s reads). i do NOT game on my phone.
My wish is for the most smooth performance of the above-mentioned, but it is also VERY important for me to have good battery life. Therefore i use Greenify and Amplify. I have limited many alarms/wakelocks, and greenified alot (not Messenger/Snapchat, because it stops notifications)
I do NOT own SetCPU, but i am using STweaks on Hulk Kernel right now.
I have usually used Ondemand governor, but found out yesterday that governors can do alot of difference, so i have shortly tried Badass, and trying SmartassH3 right now. I have been very satisfied with Ondemand governor, but i would be happy if i could get better battery life, with the same performance. For my GPU im trying 'Simple'' governor.
Furthermore ive considered the following governors; DanceDance, Badass, Ondemand, Yankactive, Smartmax, Impulse, SmartassH3 but i am not limiting myself to these, if you have other suggestions.
Thanks in advance

Here's a thread with explanation on pretty much all CPU governors and I/O schedulers.
Based on what you're saying, Intellidemand should be ok for you. It scales CPU based on the GPU load. So that means if your GPU is not working hard (gaming) your CPU should sit in lower frequencies.
SmartassH3 is more of a conservative governor.
You can even try the conservative governor. It was designed with battery in mind. Meaning that this governor prefers the lower CPU frequency. This also means less smoothness.
Another option is to activate one of the Intelli-Plug profiles from Hulk.
Eco performance is what I would suggest. It will turn your phone into a dual core phone but with some performance tweaks.
You could also try the other profiles and see what works best. But you get more battery savings by turning cores off or disabling them.

Hi
I tried the SmartassH3, but it seems it keeps rather high freqs? atleast it made my phone warmer than usual, so i am back to Ondemand until further. I activated the intelliplug and limited the cores to 2, and ive felt no performance loss yet. Which is great, so thanks for that tip
BTW, after ive begun with the governor tweaks, ive noticed my Poweramp decides to turn off when my screen is off? :/ It is not hibernated by Greenify, and Amplify has not limited either, so i do not understand why it stops. If i choose ''use wakelocks'' in Poweramp, it stays active. But this ofc. drains battery very quickly . Do you have any idea, what could be the problem here?
Check with an app to see how many cores you have active. Some said those settings don't work. For me they seem to work. But just to make sure.
When using poweramp the device will be awake anyway.
Governors should not have any effect on apps and how they run, except performance-wise. Governors can't put apps to sleep.
Poweramp requires the media service to run. Make sure you did not block that.

I've already checked with Trickster MOD kernel settings, and verified it works
Ill check up on the media service. Do you know its exact name in Amplify?

No, as I don't use Amplify.
after ALOT of tests, i think ive found out what happend. I limited the screen off max freq to 384MHz, and i think this was the problem. I will report back if it is NOT the problem. Else consider it solved
EDIT: Seems it was not. The search continues :I
