Can somebody tell me how to underclock with SetCPU? I'm using DC 3.5 with Battery Saver profile, Advanced Task Killer and Juice Defender but my battery is still abysmal (It's actually worse with DC and battery saver than it was on stock w/o root. I turned it on at 10:30, it's now 2:30 and my battery is at 75% even though I haven't done anything but respond to 1 text and take 2 pics) so someone told me to underclock. But I have no idea how to do it.
Thanks!
You have setcpu but don't know how to underclock? Running the setcpu app, hit menu button, click set device. Click yes and allow superuser to allow. All you do is move the top slider "max setting" to the left.

I was using Kings Kernel #6
At that point just d/l the overclock widget on the market, its a great add with a Kernel capable.

So now that I have read the full question, I'll answer again...
(1) - STOP using task killers, they only hurt you!!!
(2) - Download one of Kings Kernel I prefer #6, but some swear by #5
(3) - Wipe your Battery Stats in Recovery
(4) - Update Your Radio (can't tell you which but search for your ROM and people with confirmed Radio's helping, they are different for everyone.)
(5) - Go to the Market and Download "Overclock Widget" (I had success with underclocking around 650, still very responsive and not killing battery at 998)
Hope this helps, its more of just trying stuff out...
^I can't find 5 or 6. Only 1, 3 and 8. And how do you set it to 650? Sorry I'm a noob.
In SetCpu hit info, do long test. Go back to main, hit menu and disable perflock. Slide the max bar wherever you want to underclock it. If you're trying to save battery (no other reason to underclock) go to profiles and enable profiles to whatever you want. Some that i using are
- Temp >50 degrees C
Priority 100
499 max cpu 245 min (ondemand)
- Screen Off
Priority 100
245 max 245 min (ondemand)
You can also set a profile to set the cpu to underclock when the batter drops to certain rates so it will last longer (i underclock to 460 mhz at 25% so i can use it without rushing to a charger)
Im averaging about 2 and a half to three hours of use per 10% of battery (heavy use, not including standby). Send me a PM and i can give you my settings and the ROM im using.

I bet there are some of you use either the setCPU or CPU tuner on your play..
I heard it will help save some valuable juice...
I tried setCPU/CPU tuner and i think the default setting have reduce the performance when batt go before 50% or temp over certain temperature, I get annoy when i trying to fight on a 3d game...
so I really hope any expert here can advise which is the best setCPu you have used on play, for a reference for me...
beside setCPU, i like CPU tuner for the ability to toggle 3g/2g when batt is low.. so if anyone using CPU tuner instead, please share your setting for your PLAY...
heres the profiles i have on mine, in order (setcpu)gives me tripple the battery life.
ScreenOff - max 368640, min 122880
Charging - max 1024000, min 122880
Battery <10% max 368640, min 122880
Battery <35% max 768000, min 122880
scaling is OnDemand for all of them!
looks simple... but just wonder, when it move to 368... on screen off, will it automatically switch back to 1024... when we turn on the screen?
yeah. unless its below 35% or 10%
been trying out for 1 day, havnt see much improvement, but does see the batt last longer in 20% below...
i think I will try to mimic this setting to CPU tuner, which can turn off 3G somemore on extreme batt save setting, it might help more tho..
Any new tests given to improve battery life? My xperia play is rooted and am hoping that someone out there has found the best settings\profiles to use.
Please post it here. Many thanks
Anyone else use this or a similar program, if so do you get good results ?.

I noticed an improved battery usage after using 245 max/122 min (Powersave scaling) on Screen Off and then 1024 max/122 min (Ondemand scaling) as normal.
That combined with stopping all unnecessary services seems to work great so far (although I'm still looking for alternatives to improve things).
lagfree governor on main, min 122Mhz and 1.6Ghz on max
powersave governor, 122mhz min and max, screen off profile
performance governor, 600mhz max, 122 mhz min, on call profile
all priorities set on 100, using SETCPU
Except when gaming, I have it set to 768 conservative governor, stock ROM.
Also, I have screen off set to 245 max 122 min with powersave governor.
Edit/update: for some weird reason my battery life actually decreased when using setcpu, no matter how it was set. I've now disabled it, and the battery life went back to how it was before. Weird.

Hello
Does anybody use set cpu with HTC Desire ?
I would like to know wich settings work the best for you. I am trying to get the best compromise between battery life and performance.
Thanks
128MHz - 998MHz ondemand. I get more than enough life out of it. I found that if your using AOSP and not really doing much on it like just texting or calling people, capping the max to about 600MHz or 500MHz if you want, works a dream and you get even longer out of it.
Smartass is better or worse ?
I do not see any real difference between smartass and interactive in term of battery live and performance.
On demand seems to drain slightly faster than smartass.
I set my Desire to 384-1136 with interactive govenor.
I charge it once i a day each time before I go to bed anyways (sleeping time usually23.00 - 05.00), so further battery saving is not necessary to me
Edit...my normal usages are:
Syncs (no auto sync by opening):
Friendstream 4 hrs
News 4 hrs
Weather 6 Hrs
push Yahoomail
push Googlemail
push Whatsapp
push EBuddy
Active background :
Lookout antivirus
No app killer used
Phone calls : about 1-2 hrs each day
Music listening mit DSP add-on : 4 hours
Fruit ninja (man! this is addictive!) : 1 hrs
Browsing (Dolphin HD + Android market) : 2 hrs
welll....every time I charge my battery it is about 15-25% left till out of juice...if I use my phone more than those, I have to charge it earlier (more than once a day)
245 - 985 MHz Conservative give mere 36 hours power and running smooth.

For me the battery has never lasted more than a day... Even on my un-rooted one...
BTW: Battery live depends on many things
1. Your ROM and kernel
2. Your runnning application, syncs, etc.
3. your usage and settings such as cpu freq, display brightnes, airplane mode, etc.
4. Received signal quality.
5. The condition of the battery...is it top fit for example?
It is difficult to measure the battery live.
@atuladhikari : battery live has nothing to do with rooting..

I don't like using any of the other governors since I get lag. I hate lag. OnDemand gets rid of the lag for me. I've had it before where I was using smartass and it took ~30 seconds for my screen to turn back on from idle. I wasn't too impressed.
setcpu
thanks meaple for your advice
i think that set cpu is fine on "ondemand" for some roms and for others roms no
set cpu is included on oxygen settings and running well
Cool, I need to download Setcpu
128-998 ondemand
screen off 128-384 ondemand
in call 128-384 ondemand
I get very good battery and performance with theses settings.
Which app do you guys recommend? Tried overclock widget doesn't seem to be working.
Am on Insertcoin stock GB rom.

DidI do that?....I did.... LOL.
I used to use set cpu
set a profile like
Smartass
on charge - 1113mhz
80% - 100% - 998mhz
59% - 79% - 600mhz
35% - 58% - 500mhz
Screen Off - 300mhz
Priority was higher for lower battery %
BUT I stopped using it because of the little bugs, like when it changes to 384mhz for no reason after unlocking screen
It also affects the standard script with the rom you install, so you can never uninstall it properlu, you have to do a full wipe install and never install it, until I did that my phone was always a little laggy
I prefer my phone without it Each to their own
@shankly1985 - you didn't noticed wakeup lag with 128 MHz?
I must use 245 - x MHz to properly and fast unlock my phone.
Best Setcpu config for Desire is - no Setcpu at all.

I couldn't agree more with you. Experienced all of the above so no go.
245-1033mHZ with smartass give me two day out of my desire loaded with insercoin 1.0.9 with v06 kernel !
I am mostly sending Text message and some calls.

Not at all mate, I get zero lag on my phone. when I check the info on the setcpu app and time in state 128 is at 85% so my phone is using very little cpu.
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
Click to expand...

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.
Sent from my SPH-D710 using xda premium
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.
Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.
Thank you very much

What is needed to undervolt?
Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?

You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks
