We all know that our ace sucks on battery & after finding that calibration is a myth, I was kinda broken The only thing that helps us long on our battery is underclocking. There was no thread for this, so I decided to create one ! So guys, please share your frequencies, governors, I/O scheduler, rom name, kernel used & battery life for varied usages ( less, moderate & heavy ). If underclocking hasn't decreased your performance but at the same time if it has improvised battery life then it's worth sharing ! Help people love their battery that hate it like hell now

Rom: REVOLUTiON Ultimate Xperia Edition.
Cpu: min 245 - max 787
Governer: SmartassV2 or sometimes OndemandX
I/O: deadline
Still Very Fast, very smooth, no lag, less ram uses and definately get atleast 1 day battery backup with some heavy uses...

Why underclock the whole thing if you can just set a screen off profile? Using the phone while under clocked won't really give much battery. The Ace is a battery hog during screen on either way no matter what clock it's set at. All of you guys use your phone differently so that's why your battery usage varies.

Rom : PacMan Rom v22.0.0
CPU Max : 748MHz
CPU Min : 122MHz
Governor : Smartass V2
Stable and less never heats (which means less crashes)
I use Screen off Profile for underclock, Smartass, around 700 max and 200 min..
Dont use now as I amon ultimatum rom and I am testing it so dont need that but mostly I use these settings and Battery lasts 2 days
I dont play games
After trying out many ROMs and trying various combinations of Clock Speed and Govnors, i personally feel that:
FOR BETTER BATTERY LIFE- Clock Speed: 245 - 787, Govenor- ONDEMAND (am getting 1d 5 hrs battery life with 2 hrs talktime, full time 2G connected and 3 hrs wi-fi browsing using Battery Extender 1.2)
FOR PERFORMANCE: clock: 245- 806, Govnor- SMARTASSV2
To save Battery you can further UnderClock it but I feel 787 is apt.

I like the updated version cause it gives updated stats on cpu usage and it let's you know what clock speed you're running currently and yada yada lol..I really like this app..just the whole minimal thing is enough ya knw..also the updated one will not set clockspeed if your phone reboots from too high over clocking unless you force it to..

I hear you. I used to be a big fan of screen-off profiles, but, at least on the Hero CDMA, the smartass governor kept me from ever needing one again.
On the Shift, however, I could probably use one until the kernels come farther along.
Then maybe I'm the only one using this? I like it over setcpu..profiles are cool but I keep it simple

Is anyone's processor actually running at a high speed when the screen is off? I don't think screen off profiles are needed. I think they use more battery than saved.

Yep, that's the main reason for me too. My screen off is set from 286 to 768.
My normal usage is 368 to 1.4
I plug in at night with about 50% battery life at night.
Hi i install the MiniCm7 2.2.0 nAn, this ROM is awesome, everything works perfectly, and fast, but the battery is draining in a night without wifi and 3g use with step off from 99% to 55% .... (Ondemand, 19mhz-748mhz)

To overclock means to increase performance at the cost of battery life.. So make it normal n use governors like smartassv2 with FREQ- 122 to 600

I thought checking undervolt on MiniCM7 2.2 will make the overclock settings go back to default ? Since when I reboot the phone, the settings (evethough I checked the 'apply on boot') goes back to ondemand : 122 - 600 (with undervolt checked). When I leave the undervolting unchecked, the overclock value still attached even after a reboot..

no it wont mine stays at 700+ w/ interactivex after reboot. undervolt and set on boot checked
If u want to save your battery you will need to set ur cpu max to 600mhz........ Or if u make a shortcut on your destop of settings... When u dont need perfomance underclock ur cpu....and when u want.. overclock it.....dont use smartass it just reduces the overall perfomance.....better use ondemand governer...... Be sure u have callibirated the battery....

Yes I have observed changed after overclocking.. The s3 boots up way faster plus for gaming it showed me real difference specially playing real racing 2 with 1.4 and 1.7..Now I only need to undervolt correctly so I can save on my batter life.. Can we set a custom voltage for 1.7 below stock values??

stock voltage for 1.7 ghz is 1400mv, try undervolting by -50mv to -100mv and stick with one which is stable
use setcpu
keep changing it down in increments of 12.5mv and do the strees test keep doing that till u find a value that works
ps once u've done that let's us know what it is.
1088mv for 1200mHz that's the top freq I use so I never played with the voltages for the freq above it.
Hope this helps
remember thanks if it did

1704MHz voltage 1288mv (put in 1290mv it will round it down)
if that don't work or is not stable for u then the next step up is to 1300mv .

Underclocking depends on kernel, not ROM?
I've tried ICS. I have used it for a couple of months. But I then reverted to GB. It's faster, lighter, less resource hungry, no lags etc.
It's a matter of personal preference I think.
Try to choose a light ROM. With only a few performance scripts/enhancements, no excess/unnecessary apps. Real ICS as good as it is, is pretty heavy in my opinion.
~652 MHz ~ 247 MHz

Doesn't make no sense to overclock to 1184MHz.....
And 134MHz actually drains more power then 249MHz. I really wish I could give you a link to see for yourself, but I read that some time ago.
134MHz and 249MHz run on the same voltage. But 249MHz gets any job done faster then 134MHz, thus using much less CPU time. And you won't have any stuttering when playing music while screen's off with 249MHz.
That goes for all kernels. All of them have 249MHz as default min freq. Execpt MESA, which seems fine with 134MHz as far as I've seen.
Anyway, please test for yourself. Get battery monitor widget (pro). It's THE best tool for batter monitoring etc.
Thanks,I'll try.

I managed to get around 24h of standby time and around 4h of screen-on time with 2G and wifi with moderate use but the results may differ based on personal use.
These are the profiles that would help to increase the battery life without sacrificing the performance.
Profile Name: Screen On
Conditions: Screen On
CPU Max: 800Mhz
CPU Min: 200Mhz
Governor: Lionheart
I/O Scheduler: Row
Priority: 50, Exclusive
Profile Name: Screen Off
Conditions: Screen Off
CPU Max: 400Mhz
CPU Min: 200Mhz
Governor: Lazy
I/O Scheduler: Row
Priority: 90, Exclusive
Profile Name: Games
Conditions: Any of these are true(All games)
CPU Max: 1000Mhz
CPU Min: 200Mhz
Governor: Performance
I/O Scheduler: Row
Priority: 55, Exclusive
Optional
If you experience lags during music playback when the screen is off.
Profile Name: Music
Conditions: Any of these are true(Walkman,In Call)
CPU Max: 800Mhz
CPU Min: 200Mhz
Governor: Lionheart
I/O Scheduler: Row
Priority: 91, Exclusive
Note:
1.I tried this on Xperia P, but it should work on U, GO and SOLA as well.
2.People with Stock Kernel could use governors like Ondemand,Powersave and Performance.
3.Remember to uncheck "set on boot" option on any other app that changes the CPU settings like No-Frills etc to avoid conflicts.
4.Please do not ask for download link of SetCPU as its a paid app and it is against XDA rules to post Warez,you have Google for that...

Initially i had Wheatley, but since i was underclocking i had to balance performance as well as battery life....
So i used Lionheart.
You could try Wheatley and report the results.
