In my neverending attempt to extend my battery life, I installed SetCPU. The underclocking with profiles has extended my battery some, but Id like more.
I know very little about undervolting, its a new concept to me. Could someone elaborate on it, and may've suggest voltages for each speed setting? I hear it can do wonders for battery life.

just experiment, start with small increments (don't save your settings!!!) see if it reboots, if its stable for a day or two, increase it, when it starts crashing dial it back a notch.
Just like overclocking except in reverse and with voltage basically.
note I'm not sure re: kernel requirements, I haven't tried it yet with my atrix, and my current ROM runs stock kernel I think.
its hit and miss, for example on my SGTab I can't undervolt at all or else it crashes all the time, others get away with -100mAh across the board (bastards), but mine is happy on 1.1OC.

That is an excellent analogy. Basically, trial and error?

Yes, start conservative.
Another way to use setcpu to improve your battery life is to set a screen off profile to restrict the CPU speed to minimum when the screen is off.
I tried that one, but it kept stalling my phone when turning the screen back on when it was at the bare minimum.
EDIT: For anyone wondering, -75 seems to cause frequent freezes.

Think of it as tweaking the CPU of a phone to use just enough power to prevent it from failing in order to conserve battery life without affecting it's normal operation.

Any overclocking or underclocking is always trial and error. Rule of thumb is to only ever change one thing at a time in small increments, then test before adjusting again. Your approach should be methodical and not haphazard, i.e. in a PC change cpu clock speed in small increments until you fail to boot or BSOD, then change voltage in small increments until you boot and are stable again. Monitor temperatures all the time, and add cooling if necessary. If you take a methodical approach, and don't rush things, you can achieve surprising results with hardware/software tweaking.
What would be a good way to test once I increment a voltage?
Sent from my MB860 using XDA App
A good test is to just use it as you normally would. If the phone doesn't reboot, you're good to go.

So, I had checked off set at boot on the voltage screen. Unfortunately, this has rendered my phone to continually reboot and freeze, as one voltage is too low.
I do have a nandroid backup from right before installing SetCPU, and backups of working voltages, but I can't get the working ones restored before SetCPU starts and freezes my phone.
Is there a way I can default or disable the SetCPU settings without having to reflash the ROM or a backup of it?

Do something CPU intensive also to see if it crashes, like play a game. You want to stretch the phone to the limits to test it at the most extreme condition you will use it under.

Maybe a factory/data wipe?
Other than that I can't think of anything myself.
ddddddddddddd
you may try to use default stock kernel, on wich overcloking do not work.
re: setcpu, sorry I think you have to reflash... thats why you don't save the settings until you're sure
there is no shortcut way.... you may be fine for a day but next day it keeps crashing. Happened to me on my SG tab when I went to 1.2 for example, I thought it was hunky dory then a few days later crashing galore.
the longer you leave it for the better you are, its really your call to make. Some people prefer the extra speed and will live with a crash or two a week (not me, its my phone not gaming pc lol).
not sure how much stress testing you can/should do. Back when I was OCing PCs I would leave stress tests running overnight, but probably not a good idea to 100% CPU a phone overnight lol
Hey guys, anyone have a good idea of what some safe undervolting values would be? I was just going to play around with them and not set it on reboot so I could just pull the battery, but I am unsure of how irreversible the damage could possibly be, if any.
I am running: Senseless 1.0
dsb's kernel
I actually have it underclocked slightly because I don't play games, and when I do they are something like Angry Birds, or Words when I am bored.
Bump, out of all of you who have undervolted none of you know any good values?

Well, since no one will answer, I will
I generally only keep it undervolted -50mV across the board. That's just my usual set up to get a tiny bit more from the battery. The furthest I've gone is -200mV at the top. I didn't keep it like that for long, but everything seemed to run smoothly still. I'm sure I could go much lower, but I'm kind of afraid to until I know more about it.
I'm just starting to work on undervolting today since I found a kernel that works really well. I'll let you know what my phone is stable at.

Which Kernel are you running?
At -50mV across all frequencies, it reeeally varies. I never have a "normal" day with this phone. But, the shortest I've had using Ziggy's kernel from 192-1836gHz with on demand governor is around 7 hours. That was pretty heavy usage for me. Some games like Dead Space and Captain America, tons of internet, Pulse, texting, a few phone calls, music, and a little Netflix at night. The longest I've had has been 20+ hours. That's with very little gaming, a little internet, and mostly just texting. Stock battery, bump charged.
I'm really afraid to go too low, though. One time I was just seeing what would happen if I kept lowering it across all of the frequencies and it froze, then crashed. Had to battery pull to get it to work again.
I run DSB Kernel with SmartAssV2 underclocked to 1296, and before undervolting on my OEM battery I got 13 hours with a little over normal usage. Screen was on for about 2 hours total. On my extended battery I got like 27 1/2 hours, but obviously some of that time was overnight.
2 hours later I am still above 90% this is what I like to see! If I can get 15 hours on OEM battery, my extended battery will stay in my truck as my backup!

Just -50, but I updated the kernel and forgot to remove the PH98IMG prior so I set the phone into bootloops. Had to factory reset(after trying everything else) and start over from backups.

See, I don't get the overclocking hype. It isn't hard to overclock when needed, so I feel underclocking is the better choice for battery life. The phone is fast as hell no matter what.
I may try to do some undervolting...but I am running clean rom 1.3 and dsb's smartass kernel, and I have been getting good battery life for what I use my phone for. I do have it overclocked though (on demand).
You won't damage the phone with undervolting. I mean a lockup might be a pain, but it won't damage the phone. Overvolting on the other hand could ruin the phone.
I will probably just stick with -50 across the board for now, I am tempted to pay for the full version just so I can save profiles and not have to set on boot.

You sir must be using a Gnex. LOL
I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.

Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).

Hi Guys,
My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Many have complained about issues with the kernel in ICS. On any build, it is vital that you not use setcpu or any other cpu scaling app. Don't change the max/min freq, don't change the governer, nothing. Perflock will constantly reset any changes and cause the cpu to run at either full throttle or full min - no in between. Until we get kernel source and custom kernels, this will always be the case. It's something HTC does.
Many cpu monitor apps will do the same. The link in my sig has more info, and a link to a cpu monitor app that is safe to use with our kernel.
Actually when I was on the second ics leak, and setcpu worked fine. I know this because I benchmarked before and after setting frequencies
Sent from my ADR6425LVW using XDA
benchmarking doesn't mean it wasn't running at full tilt when you didn't need it to. unless your kernel magically doesn't include perflock, it was.
also, there are some combinations of setcpu and monitoring that will work. at one point if i used setcpu, cpu monitor, and one other which i forget now, it would work, kind of. definitely not recommended.
Thats why I deaded mine. Phone was constantly overheating

Agreed. I had set CPU try to disable perflock and limit to 1200mhz on conservative and it ended up being worse battery and slower overall.
You're exactly right I advise everyone I discuss the topic with to make sure and avoid trying to over ride perflock with a CPU management app. It causes a conflict in my opinion which is a huge battery drain and also causes excessive heat due to the process of fighting for its life.

the widget i posted is what you want. it should be scaling up and down, and settling eventually when nothing is really going on. the system panel that you tried clearly affected the perflock in some way. from what i understand, some apps/widgets look at the cpu itself, while others hit up the kernel for status. the ones that hit up the kernel are the issue. i'm not 100% on this, that's just what i've been told. all i know is my experience seems to match this.

Hmm, that's weird, cause I've been using setCPU with ICS on the Rezound for months and it works great! My CPU scales fine and hits all the frequencies its supposed to. The min and max frequencies do change around seemingly randomly, but anyone can see by watching the current frequency display that it is always somewhere in between the range I selected, and always appropriate for the system load.
I've always had CPU Master installed. I just removed it, we'll see how it goes.

No offense but if you can't figure out a slider, perhaps you shouldn't be undervolting.
Besides, most devs don't believe it saves battery anyway. After stopping undervolting recently myself, I'm inclined to agree

Nah, I finally learned how to do it using System Tuner. I was confused because when I moved the slider a bit, all the numbers changed and I couldn't figure out where the -25 was gonna be at. But I got it now.
Are you sure it doesn't attribute to battery life? I went a whole -100mV in general and for me it seems to have improved a bit. Not by much but it is noticeable.
Anything else you recommend? I'm completely new to the device, but I familiarize with tweaking very quickly.

You mean better stability after or during the undervolting? And what's your stand on OC? Do you also think UC saves battery as well?
Lol sorry, I just like asking people that know about these things before I try messing with them.
Yeah its more stable at stock voltages.
I recently stopped overclocking. I don't have any particular reason not to overclock. I was troubleshooting an issue and overclocking and undervolting should be the first to go when doing this. Just didn't have a need to re-overclock.
One thing I would say though... if you're overclocking, don't add more voltage than 1400 MHz is set as stock... that adds heat. Heat + clock = damage

I see. Thank you very much for all this.
But I ran into a problem. Screen flickering. When the screen is off and I press the home button, a bright flash appears then the lock screen turns on. That's the only problem I've been having and it's scaring me like crazy. I've seen some flickering issues but none like this one. Do you think it has to do with the volting? I've restored normal voltages and hasn't happened so far. It's happened twice since last night and today. Both after undervoltage. I hope that was the cause.

No, it doesn't have anything to do with undervolting. It just happened again. I really can't tell what it is.
