I'm looking to squeeze some extra juice out of my battery. What are some good free root CPU sleep or under clock apps to do so? I had one and just got annoyed. Idk what settings to choose and all that and it was showing that all the frequencies were still at 1500 MHz? Help?

Hello all. Just got my phone last night and got a new rom flashed. I was wondering what everyone is using to control cpu? I always used set cpu on my vibrant. Is there a better option for our S2 's? Thanks

Fauxclock, ocdaemon, system tuner
Sent from my SGH-T989 using XDA App
System tuner is a great app, just because it allows u to change CPU and screen off, also change the memory presents, and even backup ur apps,which is great when u reflash new roms.

SETCpu or OC daemon.

Thanks for the responses. I tried system tuner, and I guesss I need to play around with it some more. I have a question about it tho. When I open the cpu tab, it shows 2 sliders. Are they for min/max or does each slider represent a core. If anyone has some tips for using system tuner, that would be great. Thanks
The top bar is for the Max CPU and bottom of course for min if u press boot settings which is next to the govern u can apply screen of CPU which is great for battery saving...I use beast rom4.2 with smartass govern 1.13ghzmax and 383min with screen off-powersave-382 ,try getting the pro version online, hope this helps
Welcome to the DARKSIDE
So I have finally got round to taking control of my Play. Unlocked my bootloader, rooted, applied DooMKernel v14 and now have Gin2JelllyBean rom.
I've already managed to squeeze a day more battery life thanks for SetCPU down clocking while the screen is off. Now id like to look at undervolting.
From what I read, there should be an undervolting option active in SetCPU but it's not there. I thought DooMKernel supported this, so firstly I just wanted to ask if there is anything I need to do to activate it or if might have gone wrong somewhere?
Thanks in advance.

I have SetCPU too and it doesn't let me change the voltages. I am using IncrediControl for changing them, and it works
OC/UV Beater2 v1.7, allows setting voltages in an init.d script, so there aren't any unnecessary services running on boot
Thanks for the suggestions guys I will check them out.
Still confused why I can't use SetCPU though.

Be careful u dervolting, can actually decrease battery life. Never set undervolts to run at boot.

Now how do you figure that
i am using System Tuner Pro
all in one apps for CPU modding
but try SetExperia, its lightweight
My phone keeps moving the setting on cpu, it's set for 1.5 to 348mhz but when I back out it goes to 1.5 to 1.3 and my battery been dying so fast I ready factory reset my phone but still happens not running no custom kernel
Sent from my SGH-I747 using xda app-developers app
Are you saying its going from 1.5 to 1.3 as the max or the min? What are you using to adjust these parameters?
The CPU is designed to range from 96Mhz all the way to 2.1 GHz depending on the kernel. Stock is 384 MHz to 1.5 GHz. The CPU with adjust according to load. The real way to see what the CPU is actually doing is to install CPU Spy from the market.
You need to provide the kernel your using, the ROM, if its ICS or JB. You can't be on stock

im trying to set 1.5 to 348 min. but when i set and back out it goes to 1.5 to 1.3 min. im on serenity 1.2 rom and i just flashed ktoonsez kernel to see if it will stick now and it doesnot and im on Jb
Are you using ktweaker to set the values? It comes with the ktoonz kernel. And make sure it has root permissions as well.
Also install the app I mentioned from the play store (free) and see if your phone is going to "deep sleep".

i did try that ktweaker in that app it says 1.5 to 348 min but in other apps it says1.5 to 1.3 or 1.5 to 1.5 and yes it says deep sleep 4%
You might not have a problem after all. As long as the CPU is scaling from the 1.5 to 384, your phone is running fine.

deep sleep means your radio, 3g, wifi etc all pretty much shut off. The only things that 'wake' them up to sync and check email etc are 'wakelocks'.
Your phone shouldn't be in such a high cpu range unless your using an app. My guess is an app wakelock is out of control and forcing your phone to do this. If you are on a ktoonsez kernel or rom go and lock the cpu frequencies at about 918mhz. When you lock frequencies it won't go as high, but the problem of a background app setting off wakelocks won't go away
Get bettery battery stats for bettery results
Be sure to thank me!

My phone goes into deep sleep it does not have wake locks problems. My problem is in my set cpu app it says 1.5 to 1.5 min it won't let me stick anything and I just won't back to stock and had to root again and download set cpu again and it says 1.5 to 1.5 min I though maybe it was a rom but it's still doing it idk if it's just the app doing that

Is it possible to disable the second cpu core?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Kernels put the second core to sleep when not needed. I find it sleeping on mine most of the time. If are talking of disabling it totally, I'm not sure.

Yeah I kind of just wanted to disable it completely and mayne be able to turn it on and off on demand. I find it always turns the secind core on even just scrolling. What are you doing to keep it sleeping?

I flashed custom kernel, and use badass governer. Now I find my second core sleeping most of the time, and used only when higher processing power is needed.
Just now checked CPU times in System Tuner, and I realize either of the CPUs is sleeping for 87% of the time, effectively meaning that for 87% of time only one core is being used.

Actually I figured it out! im using the ktoonez kernel and if you use the ktoonsevative (dunno if I speled that right) you chanf the governor settings, look for "max cpu lock" and change it to 1...it is only 1 core.

Could you please update the thread title with [SOLVED] please.
I want to over clock my phone and under clock it when I'm not using it to save battery life is there anyway to do this I've tried a few apps and they didn't do much
What is the lowest clock rate for the phone bc on the apps it puts it at 384
Thanks for the help

The lowest safe rate would be 384 but you would be a lot better off
to get the "JuiceDefender" app from the play store.
It has a lot of features including auto cpu frequency and you can set it up
so it automatically handles all options needed for the very best battery
savings modes without sacrificing performance...
My personal opinion which is not worth much is NOT to mess with
manually over clocking, under clocking or volting but instead use a
true and tried app like JuiceDefender to do all the work for you.
Check it out at the play store.
Thanks I'll try it out

Hey i got a question about CPU. Im running wicked rom with Deviant Kernel. My max and min freq keep changing. My kernel allows me to overclock to 1944 but i set it to 1620 and min at384. im using smartsassv2 and cfq but it keeps making my maximum 1350. no matter what i change the gov. to or the max. I reinstalled rom and and the kernel seperate. to see if it would make a differecne and same results. Please Please Please help me fix this
I'm not an expert but I think I can some what help you. Are you toggling the set on boot?
Sent from my SGH-T999 using xda app-developers app
You need to install a custom kernel and possibly a custom ROM.
Then you can overclock/underclock to what your kernel supports.
I've seen kernels that allow min at 94 and max at 1944.
