In the options to save battery life there is an option to turn on a cup limiter. Is there a way to automate this? Limiting the cpu when not in use automatically would be helpful. Or does this phone implement this already? Does a program already exist to do this? Any knowledge on this topic would be helpful.

As far as I know, 8 core exynos cpus use 4 power efficient cores. so in some way they apply limiters.
I think every Android lowers the CPU frequency when not used....
Yes, but when you go to battery, and max power settings, the one thing on the list that affects the time the most is the speed limiter, which shows to add like 1200 minutes every time. I'd like to just use that alone on occasion, and not be limited to 8 apps.
Why do not you try using Tasker for this?
that wont really affect anything, the CPU will automatically idle when its not performing a task or if the screen off.

I use different kernel apps 3 c toolbox or kernel auditor and limmitnmine on the snap dragon model I cap my big cores normally to 1.9 and small cores to 1.4 or so. I would love to shut a few off but Samsung uses there own hotplug and most kernel apps can't do nothing with that
Maybe you could check this app

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?
I am using the Clemsyn Kernel now, but have never done any overclocking before.
What is the effect on battery life if I went to around 1.4ish?
What is the effect on the lifetime usage of my unit if I overclock?
After I download SetCpu, what settings do I use? Do I have to change anything in voltage?
I read something where people sometimes underclock when the screen is turned off. How can I do this?
Thanks for any help. I am a noob when it comes to overclocking.

Start off by setting your main profile to 1.4GHz and tick set on boot. And theres your overclock... I think interactive gov. is the most useful, you can try others if you want.
If you would like to limit the speed when screen off, add a profile under profiles select screen off and set your wanted frequency when screen off.

+1 This is exactly what I've done
If you set the max speed to 1.4 GHz and set the governor to performance it will drain the battery faster than if you had it set to the others. You'll most likely have already upgraded the TF by the time it dies due to overclocking. It does shorten the life, not dramatically though. You can set up underclocking in profiles.
If you have specific profiles in SetCPU and a set CPU frequency NSTools, is there anyway to keep the profiles working without having to disable set on boot for NSTools? NSTools seems to overtake CPU settings on boot.

why do you even want use SetCPU ? it seems to be useless with NSTools because what ever it can do is to be done by NSTools , if you say you wanna do something like change frequency while screen off , then the governor will do it automatically if you choose appropriate CPU governor

CPU Profiles aren't worth it for day to day use. Constant ondemand is perfectly fine and won't steal any extra battery from you.
However, setting NSTools to set on boot should still allow SetCPU to work fine, as long as CPU settings are set the same on boot time. If not, use init.d scripts but remove CPU parameters from them (find them in /system/etc/init.d/xx-xxxxx), keeping the other settings as you prefer. Might want to remove NSTools after this though as it may undo your changes after opening again.
i guess setcpu makes it easier to change cpu frequencies quickly through the widget, ns tools doeesnt have a widget so its "harder"

SetCPU won't control the Backlight Notifications and Dimmer.

I'm just a bit OCD about battery life some days. I'd rather use the app than making my own scripts. I kinda derped with the profiles earlier today. All is good now.
I wish the two would play better together too - and I don't see how "just don't use them both" or saying SetCPU is no longer needed is acceptable answers. Especially since many of us actually paid for SetCPU...
Now that it looks like we'll only get two governors in MathKids kernel (what a crock)... saying you are picking the wrong one is a bad answer too. Ondemand certainly isn't the best for battery life, and for those of us who have tested and measured battery life we know just picking one isn't a solution either.
So what is the actual answer? Because setting the governor parameters at boot isn't the problem. It's switching between profiles - and the governors that give you the best battery life and giving acceptable performance need to be tweaked from their defaults.
With OnDemand I'm looking at using over 16% battery per hour under 4.1, even with considerable screen off time. Not being able to set it to Wheatley on screen off is killing the battery.
I will say the problem seems to lay directly with SetCPU and I'm going to contact the dev and see what I can find out. I don't see why it should be changing the parameters back to default on profile change.
But people who use neither or just one probably just not comment. Not to flame, or fight, but it's not helpful to add nothing.
Hello, hope this is the right section.
I am looking for good CPU tool that can overclock the processor and control its frequency when the screen is off. So far I am using CPUBoost Lite, but you need to reapply its settings everytime after reboot (CPUBoost Lite, the newest version is a complete bullsheeeee).
I also tried System Tuner, but it has far too many scary tools, and it seems it doesnt always lower the cpu when the screen is off...
So could you suggest me another one?
really guys, am I asking something that complicated?
I'm not sure, but maybe you should consider taking a look a the App "Tasker" and the variable %CPUGOV.
There are quite a few posts here in the forum about Tasker.

Please give some details about your device so that people can post more focused replies.
I don't know much about overclocking, but for lowering the cpu when screen off - this should be automatically be done by the kernel in stock / any custom kernel that you install - are you sure your cpu is not lowered when the screen is off?

Enable USB debugging, install adb drivers, and run the following command through adb shell when the screen is off.
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Try SetCPU!It has profiles so you can set one of them to activate when screen is off.

Yes, this works great, thanks!
After doing every possible combinations of ROMs and kernels and everything else under the son I have found the recipe for longer battery life and awesome performance all you need is the Deep Sleep Battery saver Greenify app and Go Power Master Hibernate all your apps then go to Go Power Master and make Greenify and Deep Sleep battery saver whitlisted apps schedule it the way you want Deep sleep battery saver that is as too what apps to sync so often or whatever and example I am used to running my phone dead four or five times a day I charged my phone once in two days when I used this combination so forget all those setting your processor to all these different speeds and profiles just use this and you will see the difference BIG difference unless your over clocked to 1.5 GHz or something even charging the phone and talking on it your battery barely drops this is one hell of a combination took a looooot of time to figure this or but works like a charm

If you have Deep Sleep problems, that Deep Sleep Battery really helps, but just turn it off (or freeze it) after waking your phone, since it still runs on background while you're using your phones, and consume some RAM, which we don't wanna...
Go Power Master, hmm... That "Optimization" thing just means "Clear Memory" (Background Memory). So if you have Task Managers who have that function, you can ditch GPM with your own Task Manager, less Apps installed
Greenify. The best so far. Cancels-out stupid background apps that persists (much better with the new version, GSF bye-bye! ). I only stay at my unstable 4.0 ROM for this baby (and also Xposed). If Greenify can be incorp'ed with GB firmwares, that would br awesome, which is not possible...
Additional tips:
• Lessen RAM usage (meaning close other running apps, foreground or background), to lessen CPU pressure.
• "Top-Off" your charging time. Do an extra 15-20 minute charge after 100% charging. If "fills up" the mV capacity , for the best full-battery experience
• If your phone can, Underclock/volt. Even less than a hundred mHz. It save some 15-30minute more juice on your phone. Just Overclock if needed, same as Setting the CPU clock to default.
• There are Rooted phones specializes on battery saving by:
*On Multi-Cores: Stop a core(s) to run. Really helps keep the CPU pressure off.
*Kernel Governors: Smartassv2, Hotplug, blah blah blah.. Search it...
• Limit / Lessen the usage of phone while charging. I don't know why, but I think its to, uhmm... prevent the battery pressure from charging-discharging, i guess!?
• Others are pretty basic. Backlights, GPS, Data, WiFi, Bluetooth... Yeah, no need to explain..
+1 good
