So from what I've beed reading setCpu profiles are un-usable on the epic? Id really like to use a screen off profile to save battery but almost every time I do my phone freezes and I have to pull the battery. Is there something that can be done about this?

not that i've heard. i didnt have these issues using screen off and other profiles until recently. i used them on mixup kernel, baked snack kernel with no problems while others reported them. since switching to phoenix it seems the profiles give me the same issue you have. but if thats what you're using you hsouldnt need profiles as the interactive governor scales down much better (in theory) than conservative. you should also set min to 200 instead of 100. you should still get pretty great battery life without a screen off profile
I am running phoenix 1.49 and epic experience 1.2.04. Been running setCpu at 100-1200 interactive with no issues, just as soon as I enable profiles my phone freezes... so you're saying interactive removes the need for a screen off profile?
Sent from my SPH-D700 using XDA App
yeah i'm on the same setup and that same thing happens if i enable profiles. in theory you shouldn't "need" screen off profiles with interactive because its better at scaling up and down when needed. it should scale itself down to save battery when phone is not in use and therefore the screen off profile should not be needed.
most governors do this really, but interactive is supposed to be better at it
Ok so I have searched all over the forums and through google to find an answer to this and I can't any where so here goes. I am currently running the syndicate rom with the extreme kernal installed and when I go to use set cpu I have it set to conservative but any time I try to limit the cpu speed with the sliders it doesn't tae effect. The green numbers above the sliders will change stating my preferences but the white numbers that show the actual speed of the processor will continue to climb past my desired bottleneck. It looks like thecpu always stays between a range of 200 mhz and 1.2 ghz no matter what I set it at. If I change the style to something other than conservative it will change the behavior like performance will keep it at 1.2 or what I select and battery saver will keep it at the minimum. On demand and interactive seem to respond as well but are a little buggy and any little touch on the screen will make the processor jump straight to the maximum and stay there fr a bit which I would assume would kill my battery quite a bit faster. Does any one know if this is an issue with the phone, rom, kernal and if there is maybe a better settng than conservative or a different kernal I could use I was looking into the phoenix or fluff kernal. Any help or recomendations would begreatly appreciated. Thanks

Its been a long time since Ive used it (2.2.1 scales pretty good) if I remeber right,interactive is what you want to select,but on some kernels conservtive is what you want to select.I never used the profiles,I think they dont work all the time.
That's odd I never had that problem with syndicate. And I know for sure that almost every overclocking kernel recommends conservative, for some reason the other profiles can cause problems. There's a couple things that I've learned.
Conservative, for one thing, is never going to be an on demand setting. Typically it will just up the cpu to the max you set it at whenever there is some sort of activity on the phone. Which begs the question, what do you have the max set at? if its 1ghz, remember that the kernel is overclocked, so a setting of 1ghz will allow you to go to 1.2ghz. (I'm almost positive you don't want to set it at 1.2, because then it will peak higher than that) I think the max you set it to should be the listed physical limit of the processor (ours is 1ghz obviously), and the overclocking handles it from there (at least that's been my experience).
Also, remember that when there is no activity (your phones in your pocket), the cpu will be at your minimum. So you save battery in that regard, because with out setting cpu limits, like if you're running stock, I think it might run at the max all the time. (I don't that for a fact tho) again, we pretty much have to run conservative, (I've read its something to do with these hummingbirds and setcpu and overclock widget aren't built fot them) so its an all or nothing deal, you can't get "just enough" processor setting.
Try creating different conditions to help yourself out. When I had syndiccate I had a different setting for the screen being off, for being plugged in to a wall, for being plugged in to a computer, and for being below a certain battery %. Those are really cool features and help out a lot.
And as far as other roms...I use baked snack right now with his ultimate kernel. Its only sllliggghttly less stable than syndicate (but most most most defintly stable enough for a daily driver), and I get much better battery life and performance. He recommends using overclock widget, which isn't as flexible as setcpu, but defintly gets the job done. You'll have to google baked snack and find his website since they kicked him off of here.
Hope that helps, let me know if I didn't quite answer your question correctly.

From my experience,you need to set it to 1.2 to activate OC...That being said,there are some kernels that need the interactive setting to work right...and 2.2.1 scales to the lowest setting when screen off even without setcpu,thats why I dont use it anymore.I will again once we have an official OC kernel for 2.2.1.

I actually used to have bakedsnacks rom and I liked it but it became a bit glitchy on me but I did think the battery life was a bit better. I only am using eclair as I want to wait for a final build of froyo to come out from sprint so the developers can utilize it better. I tried some of the leaked ones but I prefered the 2.1 better, all of the 2.2 ones were missing minor things that I used so I switched back. Also interactive setting just keeps the processor at max clock for a really long time before it scales back down and I didn't like that. Has anyone used the fluff ondemand kernal that is supposed to be for bettery battery life with syndicated 2.1? So I have deleted setcpu but it seemed to eat my battery faster so I put it back on. Maybe I will try some other kernal configurations since I was told that I can swap kernals without looseing data.

Fluff was glitchy for me,I liked Xtreme kernel the best.
For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?
I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.
I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.
Neither. CPU tuner works best for me.

its the same thing :facepalm:
Try the inbuilt one... I think its way easier
I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?
Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.
I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).
At 1.8Ghz, I find the temp settings in SetCPU very useful.

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...
Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.
SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.
I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?
im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.
Is it just my phone that seems to run as smooth or smoother in real world use at the undervolted 1ghz setting? I haven't seen any difference in opening apps and when playing Mega Jump it stutters at 1.2ghz just as much if not more than 1.0ghz. I'm not complaining in the least as my e-peen has no relation to the speed of my phone. The undervolting is also an added bonus of running the 1ghz setting. Coupled with Juice Defender and a few battery concious settings my phone is lasting crazy long. I'm running Bonsai's stock Genocide kernel at 1ghz conservative. When I was on ACS I think 1.2ghz my have been a bit smoother.
Yes i believe its just the kernels that are out right now...
i think they recommend 1000-1200 IF you want to OC but im not sure
As Randy pointed out in one of the Bonsai threads, much more battery is saved by lower operating freqs than by undervolting... 1000-1200 will drain the battery faster than 200-1200, even with the undervolt at 1000.

I have noticed just the opposite of your OP. Running at 1000 I find that some of my games are a tad choppy at times. Going up to 1200 and they are smooth.
To be completely honest, I run at 100-800MHz on the SFR rom, no hiccups or lag differences between 800MHz and 1000MHz that I can tell, so why not run it at 800MHz.
what are your OC scaling?
Ondemand or Conservative?
100-1ghz Conservative (as recommended in the Genocide thread)
100-1.2ghz On Demand when I was running ACS.
I have personally found that setcpu is my phones nemesis. I get waaaaay better battery life and crazy better performance running genocide 0.2a 100-1200 "stock" than running any combination of settings / parameters, other versons of same kernel, or even another kernel for that matter.

Bonsai rom uses genocide kernel? I thought it was it's own custom kernel, I'm on bonsai 3.0.1 with the bonsai 3.0.0 kernel and gpu performance is much improved over stock, running @ 1.2Ghz and much improved battery life over stock eb13.
Its an optimized version of Genocide from my understanding

Ok, I've never read that anywhere before and my first thought was.....you switched out the kernel for genocide and thus caused your own performance issues.
No bonsai is not the same as the genocide kernel at all. Its their own kernel that they made.

Apologies in advance if I misinterpreted your statement (it's a bit ambiguous).
If you set it in SetCPU, then got rid of SetCPU, the change will not stick. Any settings done through SetCPU do not make permanent changes to startup scripts, but are instead applied by the SetCPU application. To make them persist, the "Set on boot" checkbox must be checked, and when this is the case, SetCPU simply does its thing quietly in the background as a service.
If, instead, you modified startup scripts to set CPU speed and governor, well, then, never mind

No, I got you. I've heard of people changing scripts in lieu of SetCPU. I just had read somewhere by one of the devs that if you set it to the 1ghz setting and remove SetCPU that the undervolting would stick. I though it would be the same for clocking. Either way my phone seems t be running very smooth without it so I'm ok with that.
I'm running Bionix V 1.3.2 with the Immortality 2.1 kernel.
What I'm curious about is everyone's preferred overclocking app?
From what it looks like, it comes down to SetCPU, No-frills, Tegrak, or CPU tuner.
No frills advertises doing the overclocking without running in the background- which is appealing.
What are your thoughts?
Im not familiar with anything other then set cpu. I like it because I set up profiles for charging, screen off and temp. Ive used it for a while even when not overclocking, just for the screen off profile.
go with set CPU that's great the profiles really help save battery

You can use Voltage Control to OC too...
Sent from my XDA app cuz I'm stalking your mom....
So it looks like there are a couple of categories the overclocking apps can be divided in to- those with profile management and without, and those for the SGS only.
Profile Management: SetCPU ($1.95), Tegrak ($1.95), CPU Tuner (Free)
Without: No Frills (Free), Voltage Control (Free/$3.84)
Both Tegrak and Voltage Control are specific to the SGS family- why would I want to buy a program that only works with specific phones when I can get a solution that will work with all my future phones?
I know SetCPU is the most commonly used solution, but I keep reading so many complaints in the forums. Does anyone have any experience with CPU tuner in comparison to the others? I'll at least tinker with it when I have time since I'll have more than 15 minutes to see if I like it.
Set cpu is horrible, atleast from my experience.
Constant screen of death, meaning after I lock phone,it won't turn on until reboot.
Instability. Lagged my phone even with oc only up to 1.2
Voltage control is what I prefer.

Well I'm using voltage control right now because its tailored to the hummingbird and I like the undervolt settings. Once you find the right voltages, your battery will be (more) amazing.
However, I've used setcpu since I've had my htc hero and it works wonders...at first when the galaxy s came out, there were conflicts and setcpu couldn't tune the hummingbird(atleast for the Epic 4g, the Galaxy S for Sprint), but that's since been worked on.
Setcpu is very straightforward. When you start it up, just tap autodetect speeds and it'll have a slider for min/max and yyou just slide it to the appropriate speeds. Then you use "governors" that dictate how the processor clocks...for example, on "conservative" the cpu scales up to the speed it needs to process what you're doing and slows down really fast when not in use. "Ondemand" is basically the same thing, but it scales high up and then lowers itself to the needed speed. "Performance" keeps your cpu clocked at its highest speed and keeps it there. Its good to run performance when you need to run benchmarks or do a lot of stuff on your phone at once, because it kills the battery faster (obviously)
Just try em out...setcpu is free on xda, just look for it in the apps section on android general I think or the g1 boards
Voltage control, be wary about, because if you mess with the ettings and don't know what you're doing, it'll corrupt your phone.

I like voltage control too and pimp my CPU mainly because SetCpu hardly ever supports the kernels I use and when it does it gives me reboots
Thank you, I'll give Voltage Control a try. Do you have any 'safe' recommended voltage settings when using smartass, and then I'll see the limits of my phone from there?
No sorry idk about the vibrant, but it sould be able to handle the uv since we're both hummingbird
When you use VC, do it one clock speed at a time. The voltage slider moves in -25mV increments. Each processor is different. For example, my phone can handle 1.4ghz unervolted by -50mV but if I put it down one more notch, my phone freezes and its FC galore. So its good to have a backup.
If you're not turned away by the amount of time it takes to tune VC, then it'll be worth it. You just have to thoroughly test the phone each time you undervolt to make sure its stable before you set it as Boot. To test just scroll around and run acouple of benchmarks.
For example, when I started my UV, I started with 1.4ghz and worked my way down to 1.3, 1.2, 1.1, 1.0, .8 and .6 ghz. Slide it to 1400MHz and then slide the voltage bar one notch to the left to uv it by 25mV. Hit apply and then run smartbench, quadrant, neocore, linpack, w/e just to make sure your phone can handle it. If it can, move it one more notch and test it out. Rinse repeat for the rest
Setcpu is way more user friendly and does what its supposed to, but vc is for power users I guess

If I do recall you could also change the voltages in setcpu. Ya know if your kernel supports it.
