Disclaimer; This does not damage your phone at all or fry/mess up your cpu. On the contrary, it helps it by not running at full capacity all the time resulting in less stress and increased battery.
This method works universally for any Android phone you're using. But you'll need ROOT for Set CPU.
IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.

The Ace sucks in battery life. We all know that. And on 3G? Don't even mention it. But here's a fix, ever tried Under clocking instead of Over clocking?
Someone brought it up on a thread a couple of days ago and I have to spread the word, that works wonders. Got my Ace running on 245 min and 806 max and a different Screen Off profile. And now from the morning till 6PM in the afternoon, its just 61% AND recorded a 7 minute video/took pictures.
Battery was the only issue I had with my Ace. But now that its fixed, I love it
When screen is on:
MAX 806
MIN 245
Ondemand governor (This governor bumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 320
MIN 122
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!
This is what CPU spy should look like when you're done:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do. 3G is the worst battery killer so this will help a lot.
SetCPU: http://forum.xda-developers.com/showthread.php?t=505419
Specific instructions for those that can't get it to work!:
On SetCPU:
Click Add profile
Where it says Profile, select it and tap "Screen Off"
Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)
Set priority (in case you have other profiles, otherwise don't bother)
Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)
Tap save
Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.
For a list of most governors detailed; check out this thread! http://forum.xda-developers.com/showthread.php?t=1242323
To check if its all working, install CPU spy from the market:

Battery Calibration
1. Turn your phone off
2. Leave charging over night
3. Turn it on
4. Leave it charging for half an hour
5. Download this app https://play.google.com/store/apps/details?id=com.nema.batterycalibration&feature=search_result
6. Open it and press calibrate battery
7. Discharge your phone down to 0% during the day
8. Charge back up to 100% NON-STOP.
This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.
The worst battery killer is 3G itself. No matter how much you try to optimize battery and underclock, if you have 3G on, you're gonna have a bad time. MAKE SURE Autosync is disabled.
Thanks to QNBT for the AutoSync off and new profile settings hint!
gotta try this one. hope this works!
Hey dude I may try that tip, but I wanted to know about the governor that you are using, is that one a battery saver?, and what about chainfire 3d? you said that you dont use heavy apps and as far as I know that one is for heavy gaming isnt it?
ps. I recommend you install Vturbo 8.5 by gadgetcheck since I didnt see it on your signature, it really works

Yeah, I'm not using heavy apps now but I do like some gaming now and then. When I do game, I crank up the processor back to normal but I rarely do. And I use Smartass governor, not really sure if its a battery saver but its working great.
And yeah, I think I had turbo 8.5. But for now, my ace runs perfectly fine so I don't really need other scripts or optimizers
CPU governors control exactly how the CPU scales between your “max” and “min” set frequencies. Most kernels have “ondemand” and “performance.” The availability
ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
interactive – Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
smartass – Included in some custom kernels. The smartass governor effectively gives the phone an automatic Screen Off profile, keeping speeds at a minimum when the phone is idle.
Thanks for the tip, works for me
Im trying smartass governor but I noticed that the battery got really hot for some unknown reason :/, and I I got back to ondemand it becomes normal. Any idea?
I would rather use SetCPu becouse a need automatic changes since I play a lot ;P
I have no idea. My phone's working fine. I keep switching between interactive and smartass. Can't really tell which one works better xD

This rom actually has a pretty bad battery life. But makes up for it with speed and stability. I'm only using the LagFree V2 script and thinking about adding TurboBoost but I'm not sure if they can work together.

I already using both.. I'thing its can work together.. But i'm not to sure cause am only using lest then 1 week..
For me, i want to using a smoth n fast.. i don't care about the battery live cause i can charge or use my secondary/spare battery..

Well, just in case you miss your spare battery at home or something, check out the edit I just made on the thread.
Will make your spare battery look like wasted money xD
Using CPUtuner now. Free and works perfectly. I dont think i need smartass governor, since it offers separate screenoff profile, where i can set everything i want, including services on/off.

Lol, okay. SetCPU is also free (on XDA). But whatever works for you is fine. My fix is just running CPU at minimum as soon as the screen is off and switch profiles when the screen is on. That way you'll always have battery to use when you want to and not use up battery when you're not using the phone.

I REALLY don't recommend leaving it at 122 minimum. I tried it today and had a lot of lag attacks. Though the battery saving is incredible, but at the cost of a lot of performance. Like taking a call, it'll lag like hell. Had a lot of missed calls today just because of that issue.
But if it works for you, then have fun!

Yeah, I noticed that a few weeks back, couldn't even answer so much it was laggy. You can set in phone call 245mhz and priority higher than screen off and it resolves that issue.
I use cyanogenmod performance for setting the clock with 245mhz min now, I don't have any wakelocks so the processor is always off (deep sleep) when the screen is off, at the same time I don't have the wake lag issue since its not running at 122mhz when it wakes.
When I OC does that mean it also Over-Volts it?
Because if it does, than it effects battery life - which i don't want
thx

if all you are asking is regarding battery life then the answer is yes, depending on the governor you are using and the scheduler the phone will spend time at the higher clock speeds which requires higher than stock voltages to sustain the higher clock speed
now if you are talking in a looser sense then no, your phone will have tables set for different clock speeds ov and uv refers to deviating from the voltage tables set up by whoever wrote the kernel.
but with comparison to stock voltages at 1000mhz yes you are over volting and it will effect battery life. how much depends on your personal usage, scheduler, governor and modem as well as signal strength in your area.

Hi there,
I have searched the forum for a suitable answer but couldn't really find one.
after experimenting with different kernels and underclocking I have always wondered what the pro's and con's are for using 100 Mhz as lowest frequency.
thanks
using cm9 latest + neak 2.0.2

Really 100mhz is useless, it uses the same voltages as 200mhz (so uses same amount of power as 200mhz) and you get a lot less performance. Also, from what it have seen I can be unstable for quite a few people. I really can't see any pros to 100mhz. I would recommend you don't use it. So you are using the same amount of energy for less performance and less stability. Hope this helps you
will give you 10 to 30 mins of additional battery life if you configure it properly.
Try siyah kernel and follow the guides in general section
I have a question related to this topic. I know that overclocking can reduce CPU life, but what effect does underclocking? Same CPU life? Maybe it increases the battery life but reduces the CPU life due to CPU not working in the native way?
Haven't found an answer for this yet. It would be useful to know about it since replacing a battery is way more easier and cheaper than anything you could do if CPU dies.
Edit: I'm refering to general underclocking (max and min frequencies, not only the min frequency).

underclocking wont affect the life of your cpu. the least underclock value will only be used when your mobile is almost idle or doing low intensity tasks, it will switch to higher frequency as needed by the task.
Siyah kernel + Checkrom...
Tried Voltage control, setcpu....
So, for specific frequency under performance governor, i can set any voltage...
Under all other governors it work ok...
Please help.

Performance governor uses only one single frequency (min freq = max freq) and is only useful for testing (benchmarks).
Do not use this governor for daily usage.
Select another governor, such as Ondemand.
You can still set min freq = max freq, if you want your phone to run on only one single frequency.
Thank you. Very good point to use, let say ondemand and min/max at same frequency... why didnt i think of that??... About performance governor, it does feel "snapier" in day to day usage, deep sleep still works and battery is not much worse as screen still uses 60% of battery.... only time when performance governor uses much more battery is if u are using gps or some background task that is preventing phone from going to sleep while screen is off...
Sent from my GT-I9100 using XDA
UPDATE: After some more research i conclude: problem is NOT due performance governor or kernel... Same think happens on any kernel and governor if you set min and max frequencies same(custom voltage set in any program will not apply). Solution is to have minimun 2 steps( for example 1200 min and 1400 max mhz in my case). Further, you can use setcpu profiles for "screen off" etc., and battery loss due this performance governor imitation gets minimal....

Just wondering if its bad to set the CPU to run at 1500 MHz all the time on the Xperia S? I am using CPU Master to set it to performance profile.
I don't think it's potentially harmful for your device.
However, it will consume much more of its battery, resulting in decreased battery life.
Possibly it will also generate more heat.
Besides, it is completely unnecessary to do so. Your phone will manage the speed depending on the required resources.
Hope this helps.
