Hi guys, I was wondering how you test the stability of your undervolting. I have been using StabilityTest but even though I always pass the stress test I know that the phone is unstable because it sometimes reboots.

Hey,
Did you manage to undervolt the phone, and it is stable?
Could you publish the voltages?
Also, which ROM, Kernel and governor do you use?
Thanks, Nir
I have s4 processor, on 2.15 hboot s off, running viper one s 2.2 and I went down like 75mv at lowest cpu frequency and 50mv across the board and had no problems at all in a month at least.
I didn't try any lower than that cause I'd rather not push it.

I tried the set cpu stress test once I think and passed but I've owned the phone for a couple months now and never had a random reboot so that's the true test I guess.

I'm on the stock (well, modded by me ) ICS 4.0.4 rom, Bricked kernel, intellidemand governor. I managed to undervolt quite well and I can say it's stable at 1,1V @1,5GHz. I could probably go a bit lower but I still don't know because I haven't find a good stress test which I can rely on. At 1,1V I have no random reboots, though.

Yes, I have tried setcpu too. But I always pass every test even if I know the phone is unstable...
Could you please check your voltage value at 1,5GHz?

I just switched to elementalX kernel for the options on first boot. Disabled dtw and enabled s2w enabled lowest cpu idle (192) and 800mv idle undervolting.
So far so good, seems like my phone is not picky at all. I've actually never had it act up on anything so far, knock on wood.
I have it overclocked to max 1.8ghz now too.
Sent from my HTC One S using xda app-developers app
You can probably go lower than 1150mv @1,5GHz. I don't see any major benefit in battery life, though. The most important effect is the cpu temperature, especially now that's summer.
You were right, I went down further to [email protected] and lowered it equally almost across the board. Still no issues.
Sent from my HTC One S using xda app-developers app
It seems the only way to safely undervolt is trial and error...
I've now undervolted the lowest frequency (192mhz with my kernel) down to 700mv (the minimum allowed) and will see if it's stable.
So far it's stable. 700mv @ 192MHz!
Same here, no problem so far
Sent from my HTC One S using xda app-developers app
To cope with the summer, I've set the frequency to 1242MHz (instead of 1500MHz) and downvolted to 900mv! So huge of a downvolt, if you think that 1500Mhz requires 1,1V. :cyclops:
The user inteface is as smooth as before, no lags at all.

I just tried going down to 925mv at 1242mhz, but I still have max cpu at 1.5ghz, tried to lower it somewhat even across the board without going too low but ended up with a freeze/reboot under load so I have to try higher than that.
I can say that mine is stable at 900mV @1242MHz. It's been weeks without a crash, so far. If your sample is a bit unlucky it's likely that it will be stable at 25-50 mV higher than mine, not bad after all.
I did just that and so far no issues. Thanks

does anyone actually get any tangible benefits from undervolting? It can't be much more than 2-3 degrees. How much battery percentage is saved on a full charge? how many more minutes do you get?
I can't say at all. My usage is never the same one day to the next and I've been using different ROMs since I started under volting. I will try to check overnight drain with stock vs under volted soon.
Sent from my HTC One S using xda app-developers app
I can't say, either. Nothing that's going to change your life, about battery life. About the temperature I haven't tested in a scientific way, but I can say that now it's cool even if the weather is really hot (30-35°).

Just because you can doesn't mean you should. You're talking a 90% OC w/ ZERO added ability to dissipate heat generated by the processor and that equals a short life.

This. I mean I can understand a modest overclock, like 1.15 or 1.2, but 1.9? Asking for problems..1.9 OC sounds like you're fixing up a small grenade over there ..to each their own though..
I don't run it at 1.9 but it can be done, I runt it at 1.1 regular.

I have to agree with you here. If it can't run well without OC then there is a prob.

Would it make sense to determine your max stable overclock and then tweak a governor (like ondemandx) to only kick in in extreme circumstances? I don't know the exact settings for something like this, but I image that it would be possible. Does anyone know for sure?

I don't over clock, at least not intentionally. I guess some roms may do this. Phone gets damn hot in the car if on the charger and I will get a random reboot occasionally, so overclocking us just going to make that worse and I have no problems running any apps speedwise.

Hi, couple questions:
I recently flashed the newest miui rom with trinity kernel superwiped, wiped dalvik cache fixed permissions even followed instructions on first page about saving battery. im using set cpu 1118 -192 ondemand
1. been through 3 power cycles still only getting hardly 5 hours with heavy usage. i have everything turned off except mobile data. no rogue apps i dont play any games. could this be my radio?
2.i flashed newest firmware without cid (one of these users made one that you could flash without supercid flashed correctly however everytime i restart it stays on htc white screen and i have remove zip and reflash rom. what could this be?
3.ive done tons of research on keeping battery usage at a minimum yet i cant figure out whats eating my battery away. im nearly convinced its the firmware that i havent been able to get to the home screen. yes everyone says "no problem here" can someone help?
Sent from my MIUI.us Sensation 4G using xda premium
Souns like your rom and kernal arent playing well together. Did you use a custom kernel on the one that comes with the rom?
Also, are you ovrclcking the cpu 100% of the time? That happened to me just this morning. Somehow my cpu got set to max and the governor was keeping it at full speed at all times.

i havent changed the kernel, i just left the trinity one that comes with the rom.
as far as the cpu im kinda confused i just set it to 1118 to 192 on setcpu. how do i know if its going at 100% and how would i turn that down? i appreciate your feedback
Sent from my MIUI.us Sensation 4G using xda premium
System Tuner is a free aspp that will show you the load on both cores.
Get that and go to the cpu tab. Watch it for a minute and see it either core is maxing out constantly. It should drop to min if you are you sitting there not doing anything.
The next step is seeing if you have a persistant app that chewing battery

Oh...and if you are maxing out a core constantly, check the governor. (Can be checked right from that CPU screen in System Tuner)
My problem this morning wasn't the kernel or ROM. It was the governor. For some reason the supposedly smart governor was maxing out the CPU constantly. I just switched to conservative as the governor and boom....battery drain when from 10% per hour this morning to 1% per hour the rest of the day.
Nice! Im familiar with system tuner but no one has ever put it like that for me. Thanks a bunch for your help bro i had a feeling those ondemand governors were kinda ify. i was thinking about putting the governor on powersave but it puts both clocks on the bare minimum and i wasnt sure if thats the safest thing to do.

I've tried with and without gpu overclock in addition to with our without CPU overclock. I always see these artifacts, although less often when I turn off gpu overclock. You might be on to something here, because it looks similar to when I would overclock pc graphics cards back in the day. I usually see these every couple of times when I attempt to open folders and when I manipulate the set CPU app.

Ps. I have gpu overclock and 1.8ghz CPU overclock.

I guess you can consider this thread part survey and part for my knowledge so I know how far I can push this phone. I am at 1728MHz max with the interactive governor and cfq scheduler. Not sure if I'm going to do any undervolting, I can get through the day with about 40% remaining, and I have profiles set up for low battery and such. I am running CM10 with the 747 (I think that's what its called..) kernel and can push it to 2.1GHz. Is it stable at that high of a clockspeed? I can assume it turns your pretty Galaxy S3 into a convenient portable stove
By the way, sorry if this is the wrong section.

Stock. I've had it clocked to 1.9. But can't tell a difference with real day to day function except for worse battery drain and phone hotter.
Sent from a SYNERGIZED GalaxySIII
I have run the KT747 AOSP kernel at 2.1 ghz for a day or more and had no noticeable increase in heat, or decrease in battery life. (lulzactive or smartass v2 with either cfq or sio scheduler, no voltage changes in KT tweaker) I also saw very little or no gain in real world performance increase, and the benchmarking apps seemed to back that up. Typically run mine at 1.809 currently. Every phone cpu is different in terms of top speed, and voltage settings. Best thing to do, is to test them and see what works best for you. These 2 links, courtesy of the Ktoonez thread, provide some great info on kernel governor and scheduler settings. Given the number of options in KT Tweaker, these helped me a great deal in terms of making changes.

Not all chips are baked equally. Some can handle lower voltages (or higher clock speeds for that matter) than others. The stock values are set such that (say) 99.99% can handle.
I put everything on -50 and then looked at which voltages are actually used a lot and put those another -25. You can tell which voltages are most used in tools like setcpu or system tuner or cpu spy.
Undervolting your CPU will not save too much battery under normal circumstances since the vast majority of power is used by screen and radios.

There was some extensive testing done with undervolting on a Nexus S and their final conculsion was that even extreme undervolting only saved ~2% from total battery drain.
I was pretty disappointed to hear the result myself, but their methods of testing look sound. I no longer undervolt anymore as a direct result of their tests.
It was a pretty good read if you want to check it out.
