hi guys, i have set cpu installed and fiddled around with it abit, does anyone have any tips on how i can use it to save my battery as long as possible?
thanks
Go to the "profiles" tab. Set up some profiles that will help you save the battery. Example: 300-800mhz while screen is off. And another, when battery is below a certain level like 25% have a profile that sets your mhz to 300-600 or less. Create a few of those profiles and you should be saving battery. Don't forget to set them after boot and to make sure they are check marked. Hope this helps you.
yeah thanks ill give it a try

I am getting decent battery life, but it seems strange that Setting Profiles would use 1/3 of it.
Any one else experience this? Or know a solution?
Thanks
when I change profile on my Nexus S and go back example default or any other profile my ringer for notifications stay at the lowest setting. Very strange, maybe because I'm using CM7 nightly.

Not sure what to make of your situation; however, out of curiosity, when you select Settings/About Phone/Battery use and click on "Settings Profiles", does a new window pop up to provide further info and if so, what info is provided?
Best Regards!
yes, right now it has used 24% of my battery, I get a new screen that says
Battery used by application 24%
Force Stop Report
CPU total 5m 7s
Keep awake 2h 47m 43s
stop or unistall the app
app info (button)
I just changed it to turn off the widget after a change, increased the rule scan periods location etc.
charging to 100% (or so) and pulling the battery to reset the clocks to see what I get. im not sure if this is recent with this device or it has been doing this since I got the nexus. I didnt see it on the Epic or Evo.
thanks
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 friendz,
Case-
I spend most of time in reading on cell, so the screen is the biggest sucker of my cell's battery juice because I set screen timeout @ max(30min). Meanwhile reading I just have to pick the information from the online/offline stuff through my cell and then remaining part is done on paper. So the 'actual uses time' of phone is less but it stretch over a long period.
Screen Dim
During above case I found cell's brightness gets dim before it gets completely dark.
I wish any way that will increase my cell's 'Screen Dim Time' and/or dim intensity.
Any app that could give the freedom to set 'Screen Dim Time' separately so that I can save some amount of juice without affecting my work(It is troublesome that every time have to unlock screen to get back to work if I reduce screen on time)
Any help would be highly appreciated.
TIA

If you read only you can reduce cpu frequency and gpu frequency to save energy
Maybe use only a greyscale colors on display can help

my requirement is case specific
cpu & gpu tweaked already
greyscale layer doesn't help coz it doesn't dim the display actually
also available apps on play store doesn't have settings which I actually want( mentioned above)

I'm already following the thread
this thread doesn't have tweak which I'm talking about
You can try to reduce the voltage of cpu and gpu, if you can
You can disinstall useless app, disinstall useless google apps (Besides the usual I am referring about google play and google play service)
You can calibrate the battery
You can put that string "ro.lcd_min_brightness=1" (without quotes) in build.prop file, located in /system/ if you have the string, you can modify the value to 1, it should set the min brightness of screen when is on min in phone settings
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
