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.
Sent from my super modded phone.
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.

Thats right, just loaded it up after rooting this bad boy and it is working just fine!
I am not responsible if you brick your device in the process.
UPDATE!
Ok so here is what is needed to run this badboy without problems.
Use only the conservative option (least problematic and no sleep comas)
I dont use the widget, i already know the speeds i set it at.
The settings stick even after a reboot, but when you click on the setcpu icon they revert back and you lose your settings. If that happens just go back and click on detect auto speeds and set up your speeds again.
Happy clocking!
what version? 2.0.1?
Were you able to overclock it past the 1ghz?
I rooted mine today and installed setCPU which worked flawlessly but I am not able to move the slider past 1ghz.
I loaded it on mine and while it *appears* to work, it doesn't seem to effect the clocks any.
heck just underclock your phones to save battery lol
I can only seem to clock mines to 800? hmm. I noticed when i first opened setcpu it was clocked to 384/245!! wow so low
edit: setting it to nexus one/snapdragon Qsd it clocks to 1ghz exact. not really sure it's working though

To see if it's working set it to underclock and then get into an adb shell and run the command: cat /proc/cpuinfo
It should display cpu data that includes the current clock speed.
I don't know if this helps but when I was in the Quadrant Standard app it has the system info. I hit it, scrolled down to cpu and it said
Current: 400 mhz, Max: 1000 mhz, Min: 100 mhz,
and I just checked it now and it said my current clock was 800 mhz, so i guess the cpu scales dynamically based on what the load is and what we are doing, thats a pretty great power saving feature.
Select 'Auto Detect'.
I believe you need an oc'd kernal to be able to move the slider past 1ghz.
Also, the dev has stated that it should be set to 'conservative', not 'ondemand'. 'Ondemand' was causing random shutdowns on the Galaxy S.
I installed SetCPU on my Vibrant too but removed it because it appears that it caused the phone to power off.
Does there need to be device specific support for a processor/device or does the auto-detect work on any processor?

Look at the post before yours.......from me.
SetCPU needs to be set to 'conservative' on the Vibrant, not 'ondemand'. Also, per the dev in the "Random shutdowns?" thread: "You can "simulate" ondemand by changing freq step in Advanced to 100%"

i have this on my rooted vibrant. Max is 1000 and Min is 100. My battery life has doubled. I have not experienced any force closes, no slowness and no freezing. the phone is running super fast and smooth. Love it. After looking at the stats, it seems like the CPU uses 400 and 800 a lot.....thats probably where the extra battery life comes into play. 1000 is used when on full load.

What are your exact settings in profiles, advanced and overview?
any one running their phone at 1Ghz all the time?
+1, hah2110 please post your settings if they're working for you so a noob like me can learn some things!
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

Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)
So I'm interested in undervolting using the stock CPU freq's, and I'm going to be using setCPU (obvi).
So, first question: Even if I want to use the stock frequencies, do I have to be using the OC kernel (0.2.1/1.45ghz at the time)? And then adjust the max to 1000mhz?
Second, I started up SetCPU and whenever I go to the voltage tab it forcecloses. This happens with both the stock enhanced & OC kernel, and I've tried fixing permissions to no avail.
All I really understand so far is that the end result is a table of CPU frequencies and linked voltages. I've OCed the hell out of desktops, but I'm lost here.
I'd just like to know how to get from starting up setcpu to ultimately popping out that new voltage/freq table.
I do apologize if this seems kinda stupid, I'm just trying to exercise caution lest I demolish my phone's innards. I've done it with many an intel.
If you just want stock frequencies, then there's no need for a custom kernel. I guess in that case, you could just use SetCPU for undervolting & profiles.
However, if you want overclock, you'll need a custom kernel.
If you're going to be using a overclocked kernel (i.e. the new Faux 1.45 GHz), then you will need to set the max to 1.45 GHz, and make sure SetCPU is set to start on boot; other wise it will stay at the stock clock speed of 1 GHz... So i guess if you only wanted the OC at certain times, you could set the max speed manually, only when you want to, and not select to start on boot.
I haven't really had any success with undervolting yet... always crashes on me & reboots. The best thing to do is make sure "set to boot" is not selected, when testing your undervolting, other wise you could get stuck in a loop, with the phone crashing every time it boots and tries to apply you undervolting values. I'd start at -25 for each and work from there... stress testing each choice with a benchmark app to make sure you wont reboot... if it reboots, then you know your undervolt was to much. Also remember that you can not undervolt more than -100 between each frequency, otherwise the undervolting will not make any difference.
I really like the profile options in SetCPU... you can set the screen off frequencies to the lowest two, that way for whatever reason your phone isn't running at full strength while your not using it. Also, you can set frequency speeds at custom defined battery levels.
Hope this helps somewhat.
It's unclear to me why it force closes. This may be a rom incompatibility or a SuperUser issue? I assume you've tried uninstalling it and reinstalling it? Updating your SU app? Try flashing to the latest Aura rom?
A few quick words about SetCPU:
1. When you first get started, do not set to "Set on Boot" in case you've undervolted too much and it crashes when applied. You can always check it later once you know the voltages are stable.
2. Between each frequency step there is a maximum of 100mV step off. Anything greater than that it defaults to native voltage. I think this is a Tegra2 issue.
With that said, undervolting is simple: simply slide the little slider on SetCPU to negative values. How much you can under-volt largely depends on your particular hardware and it is inconsistent across all Atrix's. My voltage table is as belows:
1000mhz: -50
912: -50
750: -50
608: -75
456: -75
312: -100
216: -100
I, however, did not test the limits of my phone. Many people will slowly increment the voltage lower until they start to get resets, and then they'll move it back to find the lowest stable point.
It has, however, been well established that minor undervolting improves battery life and diminishes heat generation. Excessive undervolting may actually hurt battery life. You can look around on this forum regarding the data. However, reasonable undervolting will improve battery life.
Thanks fellas, this helps A LOT.
I was so afraid I'd get 17 responses of "You're such a noob. Stop cluttering the forums" etc etc
At this point, I think that the problem is, for whatever reason, the FC when I tap the voltages tab.
I'm on the newest Aura (1.2.2.1) newest enhanced stock kernel from Faux123 (0.2.1) and the newest SetCPU (2.4). I'll try updating my SU (though I believe I did that right after I flashed.
I'll reintall SetCPU and report back.
Until then, THANKS BUCKETS fellas. I really appreciate the info and advice.
UPDATE: May have found the problem. When it first boots up it prompts to autodetect freq's or choose them manually (or something like that). I was afraid this would actually alter my CPU clocks right then and there and so I hit manual detect, saw something that said Tegra2 etc and clicked it. I just now hit 'menu' and set it to autodetect, tried the voltages tab, and no FC, so I think that's solved.
Thanks again for all the info guys! I'll start experimenting and let you know HOW LOW I CAN GO (ha).
You guys get force closes due to kernel problems. You have to ask your developments. There might be something wrong with some of your cpu voltage drivers. So yeah that's why just a tip. Only overclock when you're playing some high end game. If not stick to normal. If not your phone might get overheated and damaged

It's cool bro the problem was totally a user goof by me. I kind of agree with your OC philosophy though, primarily because 1ghz with this proc an RAM seems ample and I don't do much gaming.
Real quick:
When undervolting, should I do it one freq step at a time? Or can I do ALL of them at say -25, stress test, then adjust? Also, what's a good stress test that'll force the proc to hit all the different freqs instead of just the max clock and then the minimum when it's idling/the screen is off?

Id start at -25 for all. Setcpu has a built in stress test under info, I think. Could also try a benchmark to test it. As general rule if thumb, then lower frequencies can be undervolted more, while the higher ones take some tweaking... I can't even do -25 on my 1000, b/c ill eventually get a reboot, maybe not right away, but eventually. Every device is unique when it comes to undervolting.... just remember to not set the undervolt part to auto on boot, until you get it somewhat stable.

Got it. I figure that 'set on boot' checkbox is basically a wedding ring ha. Thanks for the advice and insight my friend.
Also (as I run my first stress test with -25 across the board) if I get reboots early on, should I assume it's the higher voltages and that I should back off on the fast end of the clocks?

When testing each frequency just set your min/max mHz to the level your testing i.e. min/max=1000. UV and stress test at that frequency and if it's stable, move to min/max=912 and so on.
FYI, my MHz might be different than yours, I'm on the stock enhanced.

That makes perfect sense- limiting the max during the stress test. Thanks for the tip bro I really appreciate it.
Okay, I looked at what ziggy and cron247 did over on XDA and tried to make it better.
This kernel is unsecured, meaning adb connects with root.
It OverClock's up to 1.836MHz.
It has the SmartAss V2 governor.
It uses my ramdisk, not the one you have. I cannot forsee this being an issue. If it becomes one, let me know.
Updates:
Version 1.1.3 changes the version of lagfree, the old one was having issues. Also removes forcing the second CPU to be online which was causing choppiness.
Version 1.1.2 adds increased read ahead, writeback tweaks, decreased dirty ratio settings, simple I/O scheduler, and the lagfree governor.
Version 1.0.5 adds mpdecision fix by Mr X, thank you whoever you are, if you removed mpdecision, put it back. Also added voltage control for you UV lovers.
The only control program I have tested to work is AnTuTu CPU Master (Free), I have had issues with SetCPU and a few others. This one does speed, governor, and voltage all very well.
Get it here: AnTuTu CPU Master (Free)
The following problems seem to be fixed at this point: governor and speed settings not sticking, smartass staying at top speed, random reboots or bootloops overnight.
READ THE INSTRUCTIONS, THIS IS A SINGLE FILE
To install this kernel:
Copy the file to the root of your SDcard.
Reboot into recovery (CWR or AmonRa).
Flash the file from the SDcard.
At the end of the flash the phone will reboot to fastboot.
Once fastboot loads, tap PWR to get to HBOOT.
HBOOT will find the update and ask you to install.
Tap Vol Up to begin the install.
When it finishes it will say tap PWR to reboot. Do it.
After the phone boots remove the PH98IMG.zip file from your SDcard.
Use AnTuTu CPU Master (Free) to set min/max/gov/voltage.
Enjoy!
Thanks to ziggy and con247 for getting us started and having stuff out there for me to get ideas from.

My favorite Rezound kernel so far. Haven't had one crash, even at max OC. Thanks so much guys at BAMF!
This kernel has been good to me too.
I just wish I could get a handle on thie weird issue. Any of these other than stock kernels seem to have the minimum cpu speed jump up to the max cpu speed, then back down constantly, and I cant figure out the deal.
I can check on mine periodically and my min says 192, than a couple seconds later it says its the same as my max. Ugh.

I noticed that as well
I also had a problem yesterday morning where my phone locked up when my alarm clock went off - forcing me to pull the battery to turn the sound off - not sure if that's kernel or ROM related (running CleanROM 1.5)

It's kernel related; I'm running rezrom and had the same exact issue with my alarm running this kernel.
Do you think ziggys is more stable?.. or do I just need to find the right overclock/underclock settings?
I seem to recall seeing them have that problem on ziggy's - but I never had that problem on earlier versions of dsb's - so maybe it's just something that is fixable for the next release
*wanders off to test it again*
This is no doubt me doing things wrong that led to this, but I downloaded the kernel through the phone browser, then flashed it from the download directory on the internal SD. When I flashed Incredikernel from there it copied the PH98 to the sdcard, but no dice on this kernel until I copied it to the sdcard then flashed it.
I probably should have copied it to the sd card myself first anyway, but I figured I would let you know!
Well this morning - my alarm clock went off - I was able to snooze it - and then a few minutes later the phone went in to boot loops - had been running stable all weekend - once I pulled the battery the phone booted back up just fine.
we'll see if it repeats this behavior tomorrow morning or not...
Call recording support in the kernel?

Nope, only Ziggy's kernel currently supports this.
I only set one alarm at a time usually, but I have one set to go off every morning at 7:30 & it has worked perfectly everyday for a few weeks now.

Curious to see what settings people are using (min/max) as well as voltage control to get best battery life. Downloaded the CPU Master Free and wanted to set it up. Thanks

My default setting is 384 - 1512. I have a charging profile that OC's slightly to 1620. I also have profiles for a hot battery (which I have never had) and power under 20% which UC to 1296 and 1060 respectively. I use sio for scheduler (although that tends not to stick). My minimum UC is 384, nothing lower (I've read of bootloop issues with lower frequencies on the Incredible).
I undervolt everything from 384 to 1404 by -50; and 1512 by 25. Everything else is default.
I have never had a crash or reboot with this kernel on stock ROM.

Decent. I can get 10 solid hours or more of moderate use when I cannot be near a charger. I can stretch it further by turning off LTE and background data. Heavy data use tends to be the biggest killer. I keep my display at 30%, too, and use smartass v.2 as default.

I wonder what is causing all these boot loops for us all. Do you guys think it's the voltage? Perhaps the software?

Good question. I haven't had a single bootloop since flashing this kernel after coming from Ziggy's. Been running this 192min/183max and UV'd -75 across the board and running great.
Hopefully I don't jinx myself.
Guys with bootloops/lockups...are you running any profiles?
Make sure you do a dalvik cache wipe....
Ziggy's would always lock up on me (multiple times per day) so I gave up on it. The only problem I have with this on (and this was a problem with Ziggy's too) is the min jumping to max.
My frequencies bounce on this kernel. It spends about equal time between the highest setting, and lowest setting. It works great other than that. My question is this bad for my CPU? I get great battery life, and performance, just scared the bouncing could be bad for the processor. Any help would be great.....
