its a paid app so therefore i will not post any links. but there is some info about using it on the galaxy s devices and how we should avoid some settings and use others to dodge the bugs...

Description:
SetCPU is a tool for changing the CPU settings (capable of overclock and underclock) on a rooted Motorola Droid, Nexus One, G1, G2, Samsung Galaxy S, or one of many other devices to improve performance or save battery.
SetCPU also allows you to set up profiles to change the CPU speed under certain conditions, such as when the phone is asleep or charging, when the battery level drops below a certain point, or when the phone's temperature is too high. See the screenshots for examples of how you might set up profiles.
SetCPU's wide feature set make it useful to beginners and enthusiasts alike. Accelerate your processor to unleash your phone's multitasking potential, or dial your CPU's speed down to save battery.
Have an HTC Sense device with a stock ROM or kernel? If you are having trouble getting your settings to "stick," press Menu > Disable Perflock. You still have to be rooted.
Galaxy S devices: ondemand scaling is recommended. There are issues with Galaxy S kernels that may result in crashes if conservative scaling governor is used, or if the sleep profile "max" value is set too low. Please do not set the sleep profile too low, and avoid using conservative scaling.
Requirements:
all Android versions
Recent changes:
2.1.0
- Significant UI and user experience revamp, including a new background for the widget, and new notification icons
- Added a quick priority swap button to the profile lists
- Significantly improved the reliability of autodetect on certain kernels
- Numerous bug fixes and crash fixes

I understand it's a paid app in the market. But if you're an XDA member you just go here:

It's not a secret...
Funny, the previous version of SetCPU specifically told Galaxy S users to use conservative scaling and that ondemand would cause crashes.
Now they're saying the reverse.
Edit: Well, I switched it to ondemand as the app dev suggested and the phone turned itself off a few minutes later...
Are we suppose to flash it thru cwr?
Edit: nm I got it.

Argh, ever since I installed this (even after uninstalling it) my phone keeps freezing randomly while asleep!

Do you have a profile for screen turn off? If you do disable it because the phone itself lowers the cpu while at sleep.

I have no profiles set. I tried doing the sleep profile but it caused some annoying lag when the phone was waking from sleep.
On demand profile settings do not work, my phone has crashed 2 times. SetCpu just doesn't work I guess.
Using Nero V 3 and set CPU isn't doing anything...max setting is set to 1000.
How did you guys get it to work and what are your settings?

Those of us using SetCPU are using overclocking kernels. Some folks might be using DOW, but I am using JAC XMOD because I'm still on Eclair as all the 2.2 ROMs annoy me currently.
(At least until I get my Bionix Blackout for Nero v3 theme finished!)

When I get a call, my Eris 'lags' or is really slow to pull up the 'caller id/answer' screen...aka-my phone starts ringing and they screen doesn't show anything until it has rung 2-4 times. At that point, I have only one or two rings to answer it until it goes to VM. I can answer with the hard button just fine, but can't see who it is calling when I do that...I am in marketing and it's VERY important for me to see who is calling before I answer.

EPST settings have not changed since I rooted (the day root was discovered)
PRL is known good and has produced no issues until Froyo...
The first place to look is your setCPU profiles and settings. What are they?
710/122 on demand
Charge:
528/122
Failsafe:
480/122
That is it.
Have you tried bumping up your bottom line speed to like 250mhz?

Priority values would be useful, but then again your low values don't seem that bad.
You are not using the SetCPU widget on one of your homescreens, are you? (A number of people have reported that causing problems, whereas just using setCPU with profiles and no widget use, things were fine).
I'm downclocking to 19 Mhz in KFV31, but I am using some of the setCPU advanced tweaks, and I probably also get fewer calls than you. (So far, no sluggish behavior on inbound calls when the phone is sleeping).

I'm having the same problem but I do have the setcpu widget running. I'm going to remove it and see if that helps.

I will disable the widget and see if that helps. Thanks!
My lag got better when I turned launcher rotation off.
Wife has rotation turned off period, and there is no lag to speak of.

ADW rotation was already off...I actually don't like rotation. It always flips when I don't want it to.
I turned up my MIN cpu speed and that made the phone wake from sleep a little quicker, but the call issue is still there. I am thinking it has something to do with the actual dialer .apk used. I think it's Dialer One?

I'm not using the same rom, but i've had the same problem before. In setcpu, try these settings:
Max:748, min:604 - userspace
Screen off max: 604, min: 604 - performance

The DEV doesn't even recommend using the "userspace" setting. And 604 as a minimum? Wow.

I have see a couple of people talk about their screen off / on call script, wherin clocks are limited to a different (lower) max freq when in a screen off / voice call state.
I did some searching and really couldnt come up with anything, if anyone can point me in the right direction that would be awesome.
Thanks!

no one ?
Use System Tuner from market
SetCPU is an application that uses "Profiles" (Not the CM ones) so that each profile can be set to a different CPU governor and frequency. This way you can set a screen off or a high temperature profile to use a lower frequency. Fortunately, SmartassV2 has a very good frequency management so you really don't need SetCPU if you are using it.
i swear i have seen something like an init.d script that does what im asking... id much rather not have another app running in the background.

1% battery drain in 4 hours... minimal screen off frequency... higher frequency only if requested by kernel. I bet your script does only the minimal screen off frequency.
You can do that in tasker app. Its paid app but you can grab a beta trial from their site.
ok... lets try and rephrase this question.
i DO NOT WANT AN APP THAT HAS TO ALWAYS RUN.
i want a scrip that will detect when the phone is in voice call state and limit the phone to a frequency of my choice.
I am starting to believe that the ICS kernel scales properly although some people may claim it only scales from min to max.
I noticed on the stock GB kernel, the exact same thing happens when trying to use CPU controlling apps such as setcpu. However, for BOTH GB and ICS without using CPU controlling app, I can see the in between frequencies being used. When I try adjusting the slider THEN it starts the freaking out in terms of min/max. (Rom toolbox)
I even notice the battery life worsen tremendously when trying to use setcpu, antutu, etc on STOCK frequencies. Perhaps it has to do with people trying to use CPU apps on a kernel with the perflock enabled?
With the absence of a CPU controlling app on ICS , my battery can last the SAME (not worse, for sure) as it on GB.
Perhaps this can help those who complain about bad battery life on ICS
Sent from my ADR6425LVW using XDA
You don't need to wonder anymore! Its a function built into HTC kernels called "perflock" and its function is to continually reset the values for the min and max frequencies in order to prevent other applications such as setCPU from taking control over the CPU frequencies.
I've been using SEbastianFM's ICS OC kernel with setCPU. You are correct, that it does scale properly even though the min/max frequencies hop around. If you take notice of the current frequency, its usually appropriate for the current load level.
Furthermore, if use setCPU profiles to control the CPU speed, I've noticed it prevents the kernel from periodically reverting back to its default speed and governor settings. setCPU occasionally crashes (FC's) about once a day on me, but since I have the widget on my homescreen I notice it starts right back up again within a second or two and starts controlling the CPU speed again.
Hi all
Here are a few tips i would like to share wid u all. These tips will help u extract the maximum juice out of your xperias
Starting wid the simplest one
TIP NO 1 - ENABLE EXTENDED STANDBY MODE IN POWER SETTINGS
If u are on stock ics rom , go to settings, power management and check extended standby mode.
yes do it, this doesn't affects battery drain but enhance the standby time .
This helps to switch off wifi and data traffic when the phone screen is switched off for sometime.
Basic but most useful.
When this is enabled , u dun need apps like Juice defender or DS battery saver
TIP NO. 2 - DO NOT USE ANY APP KILLERS OR TASK MANAGERS
Most of us use task manager to kill apps running the background regularly.
But we may notice that most of the apps killed by task managers get restarted by themselves.
Thus all these app killers continue to drain battery and do the same thing all around,
These app killers will also make your phone laggy to some extent because of poor ram management
TIP NO. 3 - UNDERCLOCK
If u use your xperia only for basic purposes such as messaging and calls then there is no problem in underclocking.
800Mhz would be fine wid minimum or no performance glitches.
This not only relives strain on cpu but saves battery.
I myself have underclocked this and belive me 800mhz does not affects the performace of most of the games(if u play)
TIP NO. 4 - USE GOVERNORS
There is no defination for governors but u can say these are the engines that control the cpu frequency time to time
There are several governors present most commonly used being ondemandx , conservative and powersave.
1: OnDemand Governor:
This governor has a hair trigger for boosting clockspeed to the maximum speed set by the user. If the CPU load placed by the user abates, the OnDemand governor will slowly step back down through the kernel's frequency steppings until it settles at the lowest possible frequency, or the user executes another task to demand a ramp.
2: Performance Governor:
This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle.
3: Powersave Governor:
The opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.
4: Conservative:
A slower Ondemand which scales up slowly to save battery. The conservative governor is based on the ondemand governor. It functions like the Ondemand governor by dynamically adjusting frequencies based on processor utilization. However, the conservative governor increases and decreases CPU speed more gradually.
go to this page to know more about governors
http://androidforums.com/xperia-mini-all-things-root/513426-android-cpu-governors-explained.html
For setting up governors (if installed) and underclocking use a free app like Antutu Cpu Master (https://play.google.com/store/apps/details?id=com.antutu.CpuMasterFree&hl=en )
here are the governors for Xperia U only
http://forum.xda-developers.com/showthread.php?t=1934749&highlight=governor ( thanks to AnDyX )
TIP NO. 5 - DON'T INSTALL APPS UNNECESSARILY
This does not needs an explanation. Just remember that when apps run in background , they consume battery. More the number of unnecessary apps running, the more faster is the battery drain.
Keep only those apps which u use frequently and if u are a rooted user, delete all bloatwares, FREEZE GMAPS AND TIMESCAPE IF U DUN USE IT.
TIP NO. 6 - CHOOSE NETWORK MODE AS PER YOUR NEED
Whether you are using WCDMA or GSM network or WCDMA/GSM , choose it as per your need.
If u are on the internet only for surfing then use GSM mode and switch to WCDMA only if u need to download.
This as per my usage has the greatest impact on battery life.
to select network mode , go to settings>more>mobile networks>network mode
While surfing only (xda ) i use opera mini app wid GSM mode enabled and its very fast .
TIP NO. 7 -SHUTDOWN ONE OF THE CORES USING AN APP "XCORE"
An app by xda member blievenhack can switch one of the 2 cores off thus saving battery
Thanks to blievanhack for app and jonathan for letting me know
Here is the post link for xperia xcore
http://forum.xda-developers.com/showthread.php?t=2057314
P.S. - charging your battery only when it is about to get exhausted belongs to old school now. Charge whenever u can charge
NONE OF THESE TIPS REQUIRES SOMETHING SPECIAL OR TECHNICAL TRY THEM AND U WILL DEFINATELY FEEL THE DIFFERENCE
I hope you like my guide, its not copy pasted , its not stolen from someone, its purely my experience.
If u find any discrepancy plz let me know.
Feel free to share your tips here and discuss your experience
Set refresh-time of app (e.g weather and news apps) to an reasonable value.
It does not make sence to update a weather widget every 5 minutes
You could also use xcore xperia. Most of the time you don't need that second core.

I haven't noticed any drawback aside from a slight lag in cpu hungry apps. Network continues to work just fine on my p.
a good guide for all..........
Settings>Devs Options>BG process limit>2 or 3
This will use less ram and hopefully increase battery
:beer:
thanks for the guide. .
Extended Standby is good but breaks apps like Cerberus or any other internet based tracking system.
Re: {tips} [save battery] {all xperias}
I think our nxt series already has d hotplugging logic so wats d point in using xcore..
I dont intend to demotivate d developer bt I didnt experience any noticable change in battery wid xcore..
And imo if we jst use a suitable governor we can save significant amount of battery..
Plz correct me if Im wrong anywhere Im still a newbie here..

Hi guys! Used to have my phone had problems with the transition into deep sleep mode. I often tune but it often does not work, or bring a temporary result. I will advise you to use the program Deep Sleep Battery Saver Pro. When I started using this program , I felt the result. Phone began to sleep well. Saving battery was palpable.
Well, should be interesting to tell us what improvement you made with those settings.
Hi everyone
I'm using SetCpu profiles to control cpu clock speed when certain conditions are met, but when it comes to app based profiles it does not work, I mean for example, if I set a profile to turn on when battery is at 30% or less, I get a notification about this profile running, but if I set a profile which must fire when GTA is running, nothing happens, main (unprofiled) MAX and MIN cpu speeds don't change, as if SetCpu couldn't or didn't listen when the profile app(s) is/are launched.
Do app based profiles work? If that's so, Do I need any workaround to make them fire? Is there other app like SetCpu having app based profile options?
I'm using stock Kernel and Rom. My phone is a Galaxy S4 Mini Duos running on Android 4.2.2 (JB), rooted.
Thanks for reading.
