Notes about Battery Saver script
Can be used with kernels that have init.d support
It completely eliminates the need for an application to set CPU speeds or profiles
Easily customizable if you use a text editor(scripts located in /system/etc/init.d)
It will set Max CPU speed to 500MHz & Min CPU speed to 200MHz when a sleep
If SetCPU, Overclock Widget, Android Overclock or QuickClock Advanced Overclock are detected, the script is ignored, so it will not affect them
Preset profiles are:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
And just an FYI, even at 800MHz, the phone still operates very well & smooth but the battery saving are the real benefit

Does this mean that if I don't use Set CPU or any app that undervolt it, the phone will AUTOMATICALLY drop the CPU speed according to my battery level:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
Another word, it will automatically drop CPU speed to 800 MHZ when my battery level is 35-0% in order to save battery?
It won't "Drop" the CPU speed, it will lower the Maximum speed the CPU is allowed to ramp up to.

So if I am not doing CPU intensive stuff and just play simple games, email, web surfing phone call, then I am not going to see battery improvement since my CPU probably don't ramp past 800MHZ anyway when I am just doing simple stuff.?
Calk's ROM undervolts the CPU at all speeds so that in itself should help a little with battery life. But you are correct, if you are not doing CPU intensive tasks the CPU probably isn't spending much time at the higher speeds.
There is an app called CPUSpy which shows how much time the CPU has spent in each frequency state.
Your phone will ramp up to 1200 mhz more than you think. When it loads a webpage, it will ramp up to 1200, when it's loading your "simple" game, it will max out for a bit, etc.
It might not stay there for very long, but still. The nice thing about Calkuins rom is that even at 800 mhz, the phone is super smooth and lag free. In fact I just turn setcpu down to 800 all the time.
Let me research setcpu and play around with it. Thanks again for the quick answers.

The way Calkulin's rom scripts are setup, setcpu gets reset on every reboot, even if you have it set to boot settings. The scripts installed will still take priority and the old rules apply, just to let you know. So you would have to set setcpu every boot for it to work, that or remove the scripts.

Team era... Does the same idea apply to the blazer 2.0 battery saving script? or does tegrak break it?
Sent from my SPH-D710 using xda premium
I havnt opened that rom, but Im gonna say the same applies, I remove those scripts, 2 will affect the cpu state.
edit, let me clarify, the scripts take prority, even if the app makes a script for init.d, the original script will take over on a reboot. So the script breaks tegrak, setcpu, and voltage control unless you set the app on every reboot.
I am running Calks 2 and desperado kernel. I notice when using setcpu, if you have it set on boot, it will override calks script.
His script does work well on saving battery life though. I ran oc'd while at 20% and still had 1700mhz blazing on performance gov.
I'd still use Calks script over setcpu or tegrak only due to the fact im too sporatic with my phone use to create optimal profiles to fit the way and when i need to use the device.

Actually in my own testing setcpu will not override the scripts, the slider may stay the same, but trust me, it goes back to 800 (or 1200 over 86%batt), Ive tested it several times. If you want proof Ill tell you how to figure it out. I know Im not respected yet, but I am someone that is known under another name that is highly respected, so, take it as you will.

Era, what's your suggestion for keeping the battery saving scripts running and getting a 1500 ish over clock when needed... something that can do both without having to physically change setcpu everytime. I basically want to permanently over clock to 1.5 and still save as much battery as possible when i have the screen off or it is charging. Idk if setcpu profiles work on this phone because i know they did not work correctly on the galaxy s. And one final question... what voltages do u run at what speeds on the "desperado" kernel to undervolt efficiently?

ERA. I wasn't looking to say that you were wrong in any way shape or form. I would be interested to know how you seen this as I am still in the beginning phases of learning the android system. I do plan on writing my own kernal/roms but I was actually sharing what my logical thought process would have been given the apps and system info I had avail.
I have a little ways to go in understanding the structure and FS of droid. Time is everyones enemy. Thanks for the correction again!

I'm currently running Calkulin's rom v2.5, and even at 41% battery I notice the cpu still hits 1.2 Ghz. Is his script activated by default or am I overlooking something? I also have nothing like setcpu installed.
okay, so when everyone says that 800MHz should be on "-25mV" what the hell does that mean? i want to improve my battery life to the max possible, 1st time undervolting so yeah...
mines is set to 1025mV
I need a profile for voltages for SetCPU only

If you're using SetCPU, you have all the tools you need. I recommend UVing -50mV at each frequency 1200 & lower. Click apply, then use your phone. If it works well enough, don't be afraid to check the "Set on Boot" boxes

appreciate your reply, may be a dumb noob statement but...
it will not let me enter "-50mV" or "-" for that matter just "50mV' and isnt 50mV way too low to be stable? i tried just "25mV" and phone froze so.... please help...
Thanks so much.
PS. it will not let me add special characters... just numbers. numbers go all the way down to "0" but not negative numbers....
If you are running calk's 2.8.1, you are already undervolted by 50mV, so no need to mess with set cpu voltages. You can however mess with the underclock settings. I for example run at 800Mhz with the conservative governor and get great battery life. However if you must mess with the undervolting in set cpu, -50Mv means 50Mv less than default. So lets say ur voltage is 1025 at 800Mhz, to undervolt it by -50 you would change it to 975 (1025-50=975). HOWEVER, as I have mentioned already, you are already undervolted -50 by default when on CALKS rom.
EDIT: To prove that you are already undervolted, here are the STOCK voltages,
1704=1500
1600=1450
1504=1400
1400=1350
1200=1275
1000=1175
800=1075
500=975
200=950
Go into setspu and you will notice your values are all 50 less than the ones listed above.

Thanks for that, I needed to be schooled. So if i'm running at 800mhz all day, why is my battery being depleted so quickly? (I get a good 12hrs per charge)
What's the lowest I can go? (stable)

The lowest that is recommended (atleast by Calk) is -100 so 100 less for each of all the values I listed above. However, if -100 makes ur phone slow or restart, try -75, etc...
Battery all depends on your usage. There are a few things you can try to improve it even more. First of all, flash rogue's newest kernel found here:
http://forum.xda-developers.com/showthread.php?t=1341564
Second, make sure to calibrate your battery. The easiest way is to download the Battery Calibration app from the market and follow the directions in the app (its fairly simple). Finally, make sure your governor in setcpu is set to conservative.
EDIT: Also, make sure you manage your running applications. I like to use the stock manager widget that comes with the phone. Allows you to close apps you are not currently using. And finally, you can try running the script found here:
http://forum.xda-developers.com/showthread.php?t=991276
It changes the way your phone uses resources to make it more efficient so it MIGHT also help battery life.
EDIT2: FINALLY, I know you said you're running at 800Mhz all day, but make sure you have your max set at 800 and min at 200. (you never mentioned you were underclocked before so just want you to make sure you are).

Means that you are running on stock voltages. That's strange as you should be at -50 by default. Either change the values manually in setcpu, or flash the zip located here:

I think it's because I'm on a stock kernel; looked it up and undervolting on setCPU only runs on certain kernels apparently. Not sure though.

You're probably expecting too much. Its not gonna make your battery last for 2 days without a charge. It has to help if you are using it correctly.
There is just no way around it. Lower clockspeeds=less battery drain.

ditto. I'm on blazerROM v3.7. I think its using the stock kernel as well. I didn't have an undervolt tab. I did set up profiles similar to calks script:
100% - 85: 1200/200
84% - 35: 1000/200
34% and lower: 800/200
screen off: 800/200
The question is, do I need to undervolt? Or could I still be getting the same results if i'm on the stock kernel with this profile set up? I just set this up last night.
I was in the same boat... had Calk's v2.8.1 ROM with stock kernel... updated kernel to Gunslingers.. we will see how it goes... Noob myself, I thought Calk's ROM would take care of everything....
This leads me to think what else am I missing?? Anything I need to do/install/tweak??...
Calk's v2.8.1 with Gunslinger 1.4.1.
Thanks much!!

I'm using Antutu CPU Master Pro and I don't find it buggy. This is better to use imo than setcpu which consumes more battery. Longpress the frequency you are in and using then set to -25mv. Tick on "set on boot" then click "apply". Reboot your phone and check again your settings if it was changed or not. Also, try to reinstall your overclocking app and clear some cache on your phone.

i do agree that antutu is very good... but the problems started when i updated to 2.5... i was using 2.3 before
is -25 the lowest it can go??? isnt -50 safe?
EDIT: also in 2.5 it keeps saying that it has been granted superuser permissions... in 2.3 it only does that whenever i change any setting...
I use OC/UV Beater2v1.7, and it's awesome! Unlike setcpu, it won't run in the background, but rather sets up scripts in init.d (don't set as permanent unless you're 100% sure of your OC/UV settings, otherwise bootloops can occur)

My phone freezes just as or very soon after i choose to overclock in cm7 settings.
My last WFS was really loving the O/C.
Has anyone any solution. Many thanks
Edit: I can use userspace govenor and go to 806mhz but dont notice any difference in speed of hone. Tried cpu spy
Perhaps it's your kernel. Which kernel do you use? (go to Settings, About Phone, Software, More, Kernel version)
Also, what apps do you use to do the overclock?
It's likely your phone. Not all chips are made the same. Set your governor to performance and slowly ramp her up till it freezes. Then take a step down and leave it.

I was going to post a link to a setCPU guide, but its no longer available
Id only push the CPU a little. In order to gain real gaming perfomance increases you need to push the GPU, but in order to do that you will need a kernel that supports it.
I only received my tablet last night and wont be rooting it until the weekend so cant say what settings ill be using yet. my aim is to attempt to overclock slightly and undervolt where I can...
You're not going to break it with SetCPU. If you overclock too much, the system will become unstable, then just back off. Also, the system will shut itself off well before any temperature possible of causing permanent damage was reached.
SetCPU has an option to create a recovery-flashable zip file, which resets the CPU settings to default. I would absolutely take this precaution, as I've had to resort to it on my old HTC Flyer tablet (became unstable, and bootlooped). As long as you select this option, you're pretty safe.
Other than that, just follow the basic rule of overclocking any computer, and push the clock up one or 2 increments at a time, then test for a few hours to see if the tablet is stable under various usage conditions. Repeat until you've either reached a desirable clock speed, or encounter instabilities.
Also, as you may already be aware, higher than "stock" CPU clock steps are normally not available unless you flash a custom kernel.
The trickster app supports GPU overclock on Civato's kernel.
If you're looking to push the GPU that's the way to go.
Thanks for the valuable inputs to all.

Does the Trickster app allow for senario clock settings. Ie. underclock the CPU on screen off or if battery is bellow a certain percentage?
I may have to switch from setCPU to it if it has the same settings and more...
