Alright, I really would like everyone's opinion on this or at least as many as possible, devs especially! I used my Juice Defender app for battery Saving (still is) but I believe the CPU function is broken as it caused tons of freezing on my Galaxy Player 4. I honestly believe it's just not functional to do such a task (the app I mean). So I grabbed nofrills since I hear about it so much on this part of the forums here on xda but had bought setcpu that applied undervolting to the CPU frequencies automatically, I have no clue if nofrills is doing undervolts. So what does the community here use? I'm open to any suggestions, no criticisms.
I also read up on schedulers but don't know which one is the best to us for our Galaxy Players. I'm using the terrasilent Kernal, so I'm using that governor. The schedulers have been narrowed down to to vr, bfq, and sio after my research - there is a thread here in the galaxy nexus portion of xda that explains everything very well. Which scheduler do you use for you Galaxy Player.
All suggestions, opinions, and comments are extremely appreciated! Thanks for reading, looking forward to hearing from you guys.
Tegrak overclock can overclock to 1300 MHz, but volt control needs the full version. Maybe the kernel disables this functionality tho, cos it only works on galaxy products.

I use tegrak ultimate. It'll handle over/underclocking and over/undervolting and will allow you to set frequencies not specified in the kernel. I have mine at 1444mhz (1360ma) right now, with 100mhz (825ma) at idle. I also use setcpu for the profile switching so I can control what frequency it's running at as the battery discharges. I usually use noop or cfq as a scheduler, but that's only because entropy doesn't feel the need to include other governors.
You just have to make sure when playing with this stuff that you have ONE program controlling the function - don't go into one program and adjust something, then go adjust the same in another. I don't really find the need to run juice defender.. these things get pretty decent battery life as it is.
I mainly use the Juice Defender now for automatic wifi turn off schedules, and only having certain apps use wifi (screen on or off only). Some apps/games pop on wifi for no reason and at weird time frames. Plus the tint feature really helps at night for an insomniac like me.
Besides that the reasoning behind this thread is to help others but to also find out why my Poweramp or anything audio related stutters when I turn off the screen and I'm thinking either it's the scheduler (using sio right now), Rom (using ethereal), clock speed (100mhz with screen off), overclocker (using nofrills), or is it the wifi being on in general still pulling data...

On a Samsung Vibrant (U.S.A.) with stock v2.2 what are the best settings, profiles, ect. for saving battery? Also please label the specifics like max/min, scaling, and your advanced settings. Thank you...
EDIT: I understand you can't overclock without a customized kernal, but if I recall correctly you can underclock without it. Am I correct?
If you underclock your phone, it might get better battery life, but it perfomance will go down too and will start lagging, i don't recommend it at all.
The vibrant doesn't like profiles with less than 800 Max, it tends to freeze on wake-up. The amount of savings from an 800 MHz screen off profile is almost immeasurable as well. Also, the default conservative governor is the only one that is reliable. Therefore unless you're overclocking to start with, setcpu doesn't do anything for battery life on our phones. Best to just use a UV kernel such as BALI.

Hey man, what you want is undervolt. Underclock will slow you down, and not make a huge difference. However I undervolt by 75mv through the spectrum and have seen great results.
can't hurt to underclock to 800 though, some kernels are ok at 400 but very laggy.

Ok, I'm posting here because after doing a search, this is the very latest SetCPU thread. Recently, we finally got a worthwhile Gingerbread JVP and several ROM's (Simply Honey 3.8 & Asgard 3.1 JUST AMAZING ROM's) have finally given us some 2.3's we can keep on our phones, well in my opinion anyway.
So, I'm using cmenard's latest Bullet GB Kernel v6.1 and have decided to finally put to use the profiles section on SetCPU. Below is what I'm thinking and would enjoy a friendly conversation of what/if any benefits can be had on Gingerbread and customs Kernels using SetCPU Profiles. I read somewhere that Android is getting much better in regards to battery/performance efficiency, but I noticed a slight fall in battery life on 2.3.4 over 2.2.1 by a few hours.
My Profiles at this time.
Main SetCPU screen
200 min - 1200 max - Conservative? Smartass? Interactive? Any particular Governor worth using other than stock Conservative? - Set on Boot = YES
I'm not quite sure how the priority works on the main screen, I mean let's say I'm at 21% battery life and its time for my battery profile to kick in, but I'm still using the phone for various reasons, wifi calling or benchmarking etc. Will the phone stay at 200-1200 or will it actually use my battery profiles?
Screen Off (Set at 10 minute timeout)
100 - 800 - Conservative - Priority 100
Battery <11%
100 - 400 - Conservative - Priority 75 (Really thinking I should delete this)
Battery <21%
100 - 800 - Conservative - Priority 50
Charging
100 - 800 - Conservative - Priority 25 (Trying to keep the phone cool)
I have read that the Vibrant does not like profiles of 400 or lower when the screen is off, and this must be true as I tried 100-400, 200-400, but they all gave me wake of death until I set the max to 800 (there was no in between a.k.a 500, 600 or 700), so now 100-800 seems to work great for Screen Off. I hate this since when the screen is off the phone does not need to be doing anything other then checking gmail via wifi and notifying me using BLN blinking. Also, I tried to set a profile for Battery temp, but for what ever reason it will NOT give me the save button, so I assume GB now controls that on its own, or cmenard has removed that option from his kernel (or setcpu is borked, lol).
Any tips or concerns with my settings above? Anyone here a guru with SetCPU profiles and can see I'm a noob with profiles? lol
Thanks

I have mine set to On Demand - Min 200 - Max 800, ive noticed though the scaling only gives me the option of - conservative - On Demand - Performance, im wondering where the remaining Governors like Powersave,etc are?
He he, you are trapped by SetCPU now.
Anyway, if you select Powersave mode you have to manually reboot the device. So it is useless.
Do you think an additional software is needed to underclock I9100's CPU? And please don't get confused by them who claims they get huge battery improvement for this app. You will get the idea after using it anyway.
Regards.
Sent from GT-I9100
Having carried out some tests using SetCPU and then not using it on Cognition ROM i found battery life to be better when i was using it particularly if i had it set to On Demand - Min 200 - Max 800.
I cant see an option for other Governors but im sure ive seen them before in a previous version,or was it another similar app?
I thought SetCPU is just a program and governors come with kernels.
Im trying to underclock the s2 when the phone's screen is off, but when i set it under profiles and put it into effect it will sometimes/most of the time, shut off when trying to awake! I've tried it at various Mhz. I had it at the lowest at first and it didnt' wake up ...so i thought not enough juice to remember all my stuff and it pooped... well i also tried it @ 800 Mhz and also had it set to powersave... im also running widget locker and about 3 widgets(twitter, beautiful widget, and notes), Does anyone know what is going on? Does anyone have any different settings that i should use instead...just trying to preserve battery life when in sleep mode.
Haven't used powersave mode at all yet, It's possible that profile has bugs on this phone.
I have my screen off profile set to 800 mhz and conservative and have had 0 issues so far.
as far as I'm aware powersave doesn't let it out of the minimum frequency (could be wrong). Use the conservative governor instead.
Don't use power save. I have done a lot of testing with this.
Here is the lowest that you can go.
Range: 200-500mhz
Mode: ondemand or conservative
If you go less than 500mhz or put it on powersaver, then it won't wake up from locking the phone.
Thanks
Thanks alot guys, have yall noticed increase battery life using the underclock?
and does widget lock take up alot of battery power? while in "sleep"?

I noticed that setting it to 200-500mhz increased my battery life by about 15-20%, but I did notice a significant performance drop. 200-800mhz is much less noticeable performance wise, but I didn't check to see what kind of battery life I got on that setting.
As for widgets...I'm not sure on that one either.

Stock kernel or codeworkx's CWM kernel?
If either of those, your screen-off profile MUST include 800 MHz or you'll encounter a sleep of death. It's a common issue with Samsungs, and it is why SetCPU has such a bad reputation on Samsung CPUs, even though the SetCPU author has created kernel patches for nearly every Samsung Android device.
If my kernel or Cyanogenmod 7, screen-off profiles that do not include 800 MHz are OK, HOWEVER:
You must not set a screen-off profile of powersave. The governor mechanics of powersave are not compatible with the "sleep of death" fix. Conservative with min=max=200 SHOULD be OK.
The reason for this is that the CPU enters and exits suspend at 800 MHz (hardware limitation). If the regulator voltages aren't set high enough to support 800 MHz - the CPU crashes.
thanks
yeah im actually flashing your kernel as we speak i looked under a battery thread and they said your kernel is good for battery conservation thanks for your help
actually i flashed it from heimdall and it says it is kernel version is 2.6.35.7 is this yours?
All kernels except my Experimental series say 2.6.35.7 - you need to use CPUSpy to identify the [email protected] that built it.
Anything that comes from me will say [email protected] or, in rare cases, [email protected] until I build a completely new system with a different hostname.

Your kernel is nice but can't oc. If I try to go to 1.4 soft reboot city.

Then your phone can't OC.
Not everyone's phone can run at 1.4 or 1.6. There's a reason it's only sold rated at 1.2... As frequency gets higher, the range of "stable" voltages (too low and you crash, too high and you overheat then crash) narrows, to the point where at a certain frequency that varies from device to device, there are no "stable" voltages.

I wonder is there any tasks or situations that might require freq above 200 while screen off? For example, while playing music or using apps like CardioTrainer (which captures gps, draws track on the map as you exercise).
Also, mine is set to 200..500 conservative for screen-off and CPUSpy shows it spends most time at 200 anyway (deep sleep taken out of consideration).

This is why I also have my screen-off limited to 500. Once in a while, the phone needs to do a little extra work, and it's better to ramp to 500, get stuff done, then go back to deepsleep. As I said min=max=200 SHOULD be OK, but personally, I wouldn't recommend it.
I would love if SetCPU allowed for different governor tuning depending on profile. e.g. make up/down threshold more battery-biased with screen-off than screen-on. (Slower polling rate, higher up/down thresholds.)

Have you tried updating the su binary in Superuser? (Even if you have the app updated, the app itself needs to update the binary.)
Beyond that I have no ideas.

Ahh, that was my problem. I was using powersave. Do you (or anyone else) see there being a benefit to having a screen off profile?
In theory, a screen-off profile shouldn't help - in reality, it's a line of defense for cases where something goes nuts in the background.
alright. ive been playing around and cant find some good governors for what i want.
for hardcore gaming, what governor have you found that works the best
for best batter saving, but still be able to watch videos, surf web, email and just general navigating without it being too slow.
which governors do you guys use for both of those? thanks

Use the smartassV2 governor. It regulates the CPU frequency according to load (sorta like ondemand except it works better).

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.

Not quite a repeat, but we do have a few threads on CPU governing. Not many people do it though.
If I MUST use an app, I use the smallest one that works. Otherwise, everything gets done with a script.

I've been using no-frills CPU Control, but honestly, there really isn't much of a point adjusting the settings on stock rezound unless you want to save power by using conservative governor and/or a lower max speed setting. It does have a nice feature to show poll the CPU frequency, though: in settings, check "Refresh current frequency" then hit the bar graph on the actionbar at top.
Stock rezound already uses ondemand governor, which is essentially the best you will get out of a stock kernel, and the frequency range is set to 384-1.5ghz by default. IO scheduler is deadline, which does not need messing with either.
Note: Do not set minimum frequency to 192mhz; it uses the same power as 384mhz at any given point in time. Also heard it can cause sleep issues.
I'm using android tuner pretty simple and let me do other stuff. Luczative gov with -50 voltage (testing so far good I'm gonna drop another -25 later)
Bump
I'm bumping the thread because it predates kernel source release and the proliferation of kernels for the Rezound.
I'd love suggestions for a kernel/CPU control app that does the following (I've tried SetCPU, Antutu, Incredicontrol, Kernel Tuner, Android Tuner, etc. and they all seem to do some but not all of the preceding):
1. Let me choose governor and IO scheduler.
2. Let me set range for CPU speed
3. Let me set profiles for (1) low battery and (2) overheat
4. Let me see and manipulate CPU voltages where the kernel permits it; and
5. Let me turn on USB fast charge where the kernel permits it (without requiring a separate app/widget), and of course
6. Won't generate more problems than it solves.
Maybe one of these already does it, but Kernel Tuner and Android Tuner completely overwhelm me with information, choices and settings that are meaningless to me. (And, no, admittedly I do not choose to spend a lot of time educating myself on the subject....I'm a professional, not a computer professional, and I really can't afford to concede the billable time. I have always taken the position these machines were tools that we use, not tools that abuse us.)
Thanks in advance for informed and thoughtful opinions.

I think CPU master is a good recommendation, chad's Incredicontrol would also be nice and it does have the fast charge function.
Antutu CPU Master, which I have been running, does not have the ability to turn on fast charge. Incredcontrol does not permit profiles.

Well it's like you said, you're probably not going to get all of your wish list. Android tuner is a new app that kinda does everything, but it also costs 10 bucks.
Neo uses kernel tuner, if that helps. Just ignore the technical stuff.
