What's the lowest you've set for Setcpu's 'screen off' profile? I tried 200 min/200 max and it didn't wake my phone when I tried turning it on. I have it set at 200 min/500 max right now. anyway to go lower than that? I'm trying to conserve battery as much as possible.
i got mine set to 200/500 mostly because 200/200 caused glitchy wakeups and occasional glitches when running background tasks with screen-off such as navigation/music/etc.
i also undervolted both 200/500 to 825mv/850mv so either way they both are barely using any of the battery
main reason for locking CPU to 500mhz max with screen off is in case something goes haywire and goes crazy on cpu, at 100% cpu usage @ 500mhz won't heat up the battery at all.
Just 200/500 for me, 200/200 at one point and no more than about 15 minutes later the screen wouldn't wake up.

I'm really struggling with battery life at the moment. Has anyone got settings I can use to save on battery life in SetCpu? Profiles etc
+1
I'd like to know too.
I would also like to know =[ my battery dies wayy too fast. I have the darkstone froyo build on my htc hd2 phone energy rom. Any programs or SETcpu settings that will help out?
If your on a rom with preflock disabled then you can underclock.
The only thing you need to change in setcpu really is to make a profile for screen off and set it to 245 (or whatever is the lowest I can't remember) both max and min (leave it on demand, or interactive if your rom has that).
This should give you about 10-15 hours longer battery life
so i wouldnt have to make any other profiles like battery? temperature? stuff like that? should i get rid of my green power and advanced task killer?
No you can keep them (well I don't know what green power is....)
The other profiles are mainly only needed if your OVERCLOCKING, however if your not touching the default max (main profile) then your not overclocking (1ghz).
To save power you UNDERCLOCK which setting a lowered screen off profile would do.
If your slowing the CPU down then the temperature will not rise, so that profile is not needed.
And you don't need to slow the phone down when your using it so none of the others are really needed either.

i think im kinda get what you're saying (sorry im kind of slow) so i had just deleted my other profiles and made a screen off one have it set to max all the way right and min all the way left, on demand, priority 100. Now on the main screen i think i touched it cause i read somewhere for max all the way to the right and min all the way to the left. This is confusing lol
The settings I have for my Desire:
Default:
Conservative 245-998
Profiles:
Screen Off - Priority 100 - Powersave
Charging/Full - Priority 50 - OnDemand 245-1305
Battery < 30 - Priority 0 - PowerSave
Running along side JuiceDefender, battery life is acceptable to me

That totally defeated the purpose of my question and others before me. Our battery lifes sucked without any programs so now we delete it?
I used darkstones froyo for awhile too. Battery drain killed it for me. I had no luck with anything. Changed to a nand build and its much better. Apparently SD builds just use more battery. With the SD froyo I could never stay below 60ma a few times would drop to less than 10ma but just not consistent. I lost about 8% an hour in sleep mode. Give a well designed nand build a go. In sleep I hover AT 4ma. My battery with Moderate use easily last the day, heavy use (multiple calls, emails, and browsing for an hour or two) still does require a recharge
Im using carbon ara theme with pcb just turn data off wen aint using it via toggle and have a profile for sleep in set cpu for min and max of 245 and from full charfe at 7am by 6 pm im still 65%. Thats using fb checkin email playing angrybirds and checking the forum

I also use advanced task killer and kill all tasks wen not in.use

bad idea as you are actually making your battery work more by doing that.

Hi,
I purchased SetCPU last night from Android market but I am unable to select the correct settings for it. I tried with 'Powersave' preset as I was going to sleep, but after 5 mins when I checked my phone it was off! and I had to turn it on. Every time I select Powersave mode it is forcing the phone to go off. Then I selected 'Ondemand' preset and went to bed at 0245 hrs. Today when I woke up at 1200 hrs ( ) the battery was at 48%, while yesterday night when I selected ondemand preset it was at 53%, it's a gap of 10 hours, in the mean time the Phone was in Flight mode and everything was set to OFF. So that's a 5% battery decrease overnight. But before that, when I was at all Default settings without SetCPU installed the battery was decreasing at a rate of 2-3% overnight under same settings. So I wonder after installing SetCPU the battery back up isn't extended but actually decreased. So I was thinking it may be a problem with my settings. Can you guys please tell me that what settings should I use to get the maximum juice out of my battery and that without compromising the clock rate of the CPU? Isn't there an Automatic settings that the CPU will run at Full speed when needed and check it's speed when in Idle? I thought 'Ondemand' preset would serve that purpose but I was wrong I guess!
Thanks in advance.
Here is a screen from SetCPU,
Regards.
I've got the same problem,any help would be appreciated.
Max 500 Min 200 and work from that adjust as needed .

Oh! And by setting the upper limit to 500 MHz we won't ever be able to use the CPU at 1200 MHz, great. I should've stick with my S8500 then, eh? What do you say?

aren't you eager to criticize. there are something called profiles. does your phone require to use 1.2 ghz in sleep , low battery conditions or overheating conditions? galaxy s2 uses ondemand governor at 200 to 1200 by default. meaning when it needs power it will ramp up to 1200. it does this in steps higher than battery saving governors so you spend more time in 1.2 ghz
my advice
sorted by priority
screen off = 200 - 500
in battery < 30 use 200 to 800
overheating = 200 - 800
charging = full speed
regular use when no profiles apply = full speed
Does anybody know what the ondemand governor uses as it's default screen off settings. By that I mean if I have profiles disabled in setcpu and just allow the ondemand governor to determine frequencies and I leave the max min freq's at default values, then what happens when the screen is turned off?
I know the cpu will eventually go into deepsleep but there are inconsistencies.
If I dont use setcpu and just allow the default kernel settings (im on doomlords btw) to determine the frequencies, then when I turn the screen on after leaving the phone for a while, the cpu speeds up very quickly and the system becomes responsive before I can ever notice.
If I use setcpu however, with a screen off profile set to ondemand, max 245, min 120, then it still takes achieves deepsleep as often as not using setcpu but there is a noticeable lag and stutter for about 5-10 seconds as I turn the screen on to use it again.
Does anyone have any idea;
A) Why this happens?
B) What is the default screen off behaviour for the ondemand governor on doomlords kernel.
you may need a program like system monitor to record your % of cpu activity, im on stock rom and i have it at 100 - 300 mhz max when screen off, i used the program while im asleep to see if there was issues but there was none or lag when the screen turned on
there isnt any inconsistency with mine,but then again i removed alot of the programs i dont use to have very few programs running in the background,playing music with this setting doesn't cause issues
i havent read alot into his kernal yet,guess you wait till someone that has more knowlege in his rom.
[v03 onwards] added new CPU governors:

Having some major headaches with my Note 2 right now. I'd previously had System Tuner set to cap screen-off frequency at 800MHz, with the pegasusq governor still selected. That was causing heavy drain (1-2% per hour) while idle, so I tried yesterday evening to scale it down to 200MHz with the powersave governor for screen off. It worked in the sense that my battery stayed flat at 67% overnight, but the phone took forever to come out of sleep so I could turn off my alarm clock, and then it started some type of fresh torment where it would freeze at the lockscreen and need a battery pull to reboot.
I switched the frequency to 500MHz this morning, but it's still locking up. Struggling to boot, too. I'd really rather not go back to 800MHz and pegasusq, but will if I need to. How do you guys have your screen-off behavior set in System Tuner, and has it caused you any problems? I'm on stock rooted, by the way, debloated by myself a while back.

I don't use system tuner, but in setcpu my screen off profile is set for 200-500 with pegasusq/cfq. I use almost no battery when my screen is off, and the wake up time is no slower than stock.

Thanks for that. I had to restore (luckily I'd done a Nandroid yesterday!) because the system wouldn't boot past the Samsung splash. I've been anti-Juice Defender for a while here, but it seems like a decent chunk of the problem with my battery has been wlan_rx_wake, most likely caused by network traffic. That's what I get for letting my wife share my phone's wifi router instead of leaving her on the house.
Much as I hate to do so, I've put JD Ultimate back on my phone in hopes that its control over wifi and data will prevent those wifi and data wakelocks from happening. Hoping that 500 max with pegasusq (I'd put it back at 600 after restoring) will alleviate things.
2 parts - one question one observation.
Stock everything.
While playing around with battery savers that change cpu frequency when the screen is off, I noticed no thrills cpu stats, that the default GRAND`s behavior is to auto switch to 312MHZ and deep sleep while idle and screen off, is that the case? is there no real need for apps like no thrills cpu/cpuspy to set min-max?

Yes, our Galaxy Grand will auto-reduced the frequency to lowest 312MHz on stock kernel when the screen is off, after a few moments later it will enter deep sleep which will conserve battery usage.
Unless you want to Max / Min performance all the time, I would say yes, you don't need those apps to take control over your CPU frequency.
It seems like the min-max is working beyond the screen off situation,
even if the defaults shown by no thrills cpu are 1200MHz .
