Hi Bala, thanks a lot for making this post, it has helped me infinitely. I just have one question:

In my battery stats it says Android OS consumes about 24% - 32%, but I don't know why. Is this normal?

My signature is up to date and my settings are:

CPU: max 1400 - min 200 (screen on 500), no uv, lulzactiveq + deadline

GPU: 266:900, 350:950, 440:1000, 533:1025, 640:1075, stock thresholds and no uv.

Screen: Touch Boost level - 1000

I really love the speed and responsiveness of this setup, just wanted to know if the battery use was because of any of the stuff written above.

EDIT: I read some posts before that I could try reflashing the kernel. So I did, and the percentage seems to have lowered to 21. I hope it was only due a time of adjustment. Either way, I still think the batt could handle about 14 hrs without charging it.

EDIT 2: Levels are now within normal values and the phone is still fast and responsive. Thanks anyway.

i dont think that many user use to under or over vol-ting their expensive devices concerning it might damage their phone but anyways its always good to have as many options as u can.

Use Yank555 kernel 2.8b. Its good. Or use a custom ROM like Sotmax which has Yank555 kernel overclocked to 1.6 ghz by default.
[Galaxy S III General] SleepinDevil:
This thread is definitely the most useful one I've read in a while! Thank you so much for all the information. I had no idea about overclocking till now
[Galaxy S III General] antonyyip:
For those not rooted or without PC troubleshooting knowledge, your statement may be correct. Once u rooted and come to xda, u are definitely like to explore more about the capability of your phone.

Just like me, after performing o/c CPU & GPU and u/c volt, I got faster and smoother performance and longer battery life, why not doing so?
[Galaxy S III General] kachrukamble:
@Bala

can you elaborate lil more from above post; what exact file Name contains this kind of script in system/etc/init.d??

bcoz every custom Rom devs tweaks kernel their own..

Hi i have a question here,

why does the CPU keep staying at 1Ghz when i am playing a game? i have OC-ed it to 1.5 Ghz, however, it just stays at 1Ghz for most part of the game. anything that i have done wrong?
[Galaxy S III General] mbalun:
Maybe it doesnt need that extra .5 Ghz ?

Milos @ Galaxy S3
[Galaxy S III General] RedDevils88:
but the game isn;t running at full speed (wild blood)
[Galaxy S III General] xcly:
Are you running any other apps that tinkers with OCs? I'm not sure which overrides other apps but maybe that's what happened.
[Galaxy S III General] RedDevils88:
i dont think so, i have siyah kernel and SetCPU installed. might be caused by SetCPU?
[Galaxy S III General] xcly:
Check the cpu section on setcpu. Or maybe you set profiles on setcpu that limits your clock.
[Galaxy S III General] tbudicin:
This is my table.

[Galaxy S III General] LenAsh:
Some users may need to note, in case they think they're going mad, that V1.30 hardware (post September i9300 build phones) have a few hardware updates including a later stepping CPU (also used in the Note 2). The stock voltage table differs from the OP (all voltages are lower for a given frequency).

See attached

This also has implications for easy overclocks of course as the same CPU stepping is used in the Note 2 at 1.6GHz stock.
[Galaxy S III General] Amos91:
Sorry for the noob question which has probably been answered before!

When running StabilityTest, even at stock 1400mhz the cpu clock drops to 1000mhz. It sometimes goes back up to 1400 but then drops again soon after. Why is this?

Edit: This is on the perseus kernel with omega v36.

Edit2: CPU seems to get to 78C then switch to 1000mhz. When should it be throttling?
[Galaxy S III General] 23Six:
Lock the CPU to one frequency by making the min and Max the same.

Or using performance governor which will lock it to max allocated value.

Powersave governor does opposite

Sent from my GT-I9300
[Galaxy S III General] bala_gamer:
it should start throttling around 78c margin.
[Galaxy S III General] flipward:
Cannot reset to default voltage

Hi! My phone keeps rebooting because I think I undervolted it too much. I tried flashing it with the file included in the first post using CWM, it says installation successful but it still keeps rebooting.

Need help..
[Galaxy S III General] bala_gamer:
the zip in the op supports only the mentioned apps. you can try reflashing the kernel
[Galaxy S III General] Amos91:
So I can't even test stability at stock 1400mhz. Is this unusual?

Happens with it using the performance governor too.

presume this also explains why it stutters playing vice city? I imagine its throttling back to 1ghz or less.
[Galaxy S III General] bala_gamer:
ofcourse u can test it, ensure your cpu temp is normal before beginning the stress test, give enough interval between tests
[Galaxy S III General] darkbahamut:
Quite a number of mobile chips actually can't maintain a 100% load for long without throttling. If you look at the Anandtech review of the Exynos 5 power consumption, you can see that also throttles when an extended CPU load is applied to the chip. Most chips these days are designed to give good 'burst' performance (for example, loading webpages quickly), but become thermally limited if the load is extended as they have no cooling to speak of.

That said, the voltage applied to a chip is one of the biggest factors in it's power consumption, and thus it's temperature. I wouldn't worry too much about what the chip is doing stock and look at getting it undervolted. This should drop your CPU temps down nicely.

Also, if you think it's throttling in games, the GPU responds well to undervolting. The GPUs heat generation will also push your CPU to throttle as they share the same chip, so undervolting the GPU may fix any throttling you are getting there.

The starting temperature wouldn't have any impact of if the chip throttles or not. The temperature the chip will hit during stress testing is depending on the chips current power consumption and the rooms ambient temperature. All starting at a higher temperature will mean is that the chip will hit it's peak temperature a few seconds earlier, but it will not change what that temperature is for the given ambient conditions.
[Galaxy S III General] bala_gamer:
I don't remember exactly but I read the throttling on exynos5 at Anand was due to immense load, not only stress testing. Rooms ambient temperature doesn't plays that big role here in thermal throttling, and I have temps always around 35+c in my home and It never was an issue, but higher voltages along with frequent testing without enough gaps will surely throttle the cpu down. :)

《posted from samsung rom》
[Galaxy S III General] darkbahamut:
Exynos 5 also had TDP throttling, but you can see from the graphs they post that when the CPU speeds drop, it starts off with small drops, then the time it spends clocked down extends over time - exactly the behavior chip suffering thermal throttling show. It wouldn't be unrealistic to expect it either. 4W power consumption is more than Exynos 4 uses for it's CPUs, and those can also suffer from throttling. It will certainly be interesting to see how this gets managed in Exynos 5 Octa for sure :)

Ambient temps will make less of impact against system that are actively cooled, but it will still make a difference. If your ambient temps are ~35C, then your phone CPU temps could never be below this, where-as my phone idles at 24C. That's a pretty big difference. It will also make a difference in how quickly your CPU temps drop. My phone at 1.5GHz after ~13 minutes of stress testing hits and stablisies at 60C. Within 10 seconds of stopping the test, CPU temps drop to around 30C.

In theory, in the amount of time it would take someone to stop a test, switch apps, change CPU settings, switch apps again and start testing, the CPU is almost at full idle temps, and it certainly wouldn't be enough to make the difference between a chip throttling or not in it's next run.
[Galaxy S III General] Amos91:
I had my phone in deep sleep for a few hours. Did a stress test and it lasted no more than two minutes before it throttled. The cpu is slightly undervolted atm but I haven't fully tested how low I can go. This is how it stands atm:

https://www.dropbox.com/s/mqa5sklmiuxj9b7/Screenshot_2013-01-11-15-01-15.png

Will have a play with gpu but I was doing a cpu only stress test. Don't know how people can properly stress test these higher clocks if it throttles. Or is it just me?
[Galaxy S III General] bala_gamer:
@darkbhamut

May be the 28nm process might help Exynos octa, but it's still a mystery how they would push higher clocks maintaining tdp along.:D

Reg temperature for me it maxes around 65 with 1.6ghz clock stressed and idles around 40c at day time, much cooler at nights.

《posted from samsung rom》
[Galaxy S III General] darkbahamut:
The switch to the half node process was interesting actually. \i think it's a sign of show thermally of power limited these chips are becoming. Usually companies either stick to the full node or half node processes, with very few (if any) every swapping from one to the other to gain a smaller advantage. The millions of dollars of R&D costs involved in such a switch must be huge. I guess Samsung view these costs as worth it for a lowly 4nm process change. It really shows how much the mobile business is worth to them! :)

The GPU settings aren't likely to affect the CPU stress testing, no. Probably only games.

Your voltages show you have a slightly 'worse' chip, as your default voltages are slightly higher. Yours are 12.5mv higher than mine, which are in turn higher than some others have reported. I guess your chip could be suffering from higher leakages, otherwise it would be difficult to explain why it's so much hotter at those speeds. It definitely hitting 78C when it's dropping?

Mine averages ~60C at 1.5Ghz 1200mv.

Hi there, I would like to know which files are involved in this process (OC & UV), I would like to have a copy of them.

Is this possible?

Thanks!
[Galaxy S III General] Ubimo:
I would also like to know where the OC & UV settings are stored/applied to.
[Galaxy S III General] Amos91:
Managed to get the stability test to last 4 minutes without throttling from 1400mhz to 1000mhz. Running at 1150mv.

Seems to idle at about 39C.

Looks like I've got a rubbish chip for thermal capability :(
[Galaxy S III General] davelikestacos:
Hey all,

Just curious, is it logical to set my Min and Max processor speed at the same level? Right now I have my Max set to 1809Mhz at 1215mV and my Min set to 918Mhz at 1050mV, but I was wondering if I could set the Min to the same as my Max level and get a performance increase since the processor would then be running at a constant 1809Mhz. Would this work out to be a performance increase? Or could this fry my chip? Are there any better Min/Max settings I could use? Are there better voltages I could use? My S3 is very stable and quite responsive, but occasionally I'll experience a short burst of lag for a split second and I wonder if that's because my Min processor speed is set so low.

Any feedback would be appreciated. Thanks all :D
[Galaxy S III General] darkbahamut:
The lag is probably more from I/O rates and GPU scaling than it is from the CPU itself. Running at 900+MHz as a minimum speed will just be using battery for no reason at all. My advise would be to return your minimum back to default.
[Galaxy S III General] davelikestacos:
What is the default minimum speed if you don't mind me asking? Also, I am using mw86 Governor tweaks and freecharlesmason I/O Scheduler tweaks from this thread. I am really looking for a good balance between performance yet awesome battery life. I am using a Galaxy S3 L710 with Liquid Smooth Jelly Bean 4.2.1 Beta 2 and the KT747 kernel. I'm using the bfq I/O Scheduler and the ktoonservative Governor.

Any help/advice would be greatly appreciated.
[Galaxy S III General] darkbahamut:
I don't have a Snapdragon S3, but I would guess around 100-200MHz. Your always likely to get a tiny bit of lag on these devices as the chips comes out of there aggressive power saving modes. The changes you've made are likely about as good as it will get, so I'd just reduce the CPU min speed to help the battery and leave it as that :)
[Galaxy S III General] davelikestacos:
Sounds good man, I appreciate the feedback. Yeah, the lag is usually only when the device is first booting and loading startup scripts or when I wake it up from powersave/sleep so I guess that small bit of lag is to be expected.
[Galaxy S III General] onfire23:
I believe the cpu is throttling earlier than 78c......I also think battery temp above 41c also does throttling before hitting the cpu max temp
[Galaxy S III General] soulzero:
Doesnt undervolting the cpu cuts performance a little bit?
[Galaxy S III General] Prominence19:
No it doesn't. The problem is stability. Underclocking is good to lower the heat generated and impact on batterylife. If you undervolt too much, your device won't be stable and would shut down. Find the sweet spot.

Should I do anything else?

sgs3 thermal throttling

@Bala

do you know that cpu throttles when the battery reach 41C on Samsung based roms? (doesn´t matter if the cpu its only at 60C)

anyway to rise that level (41C) or deactivate that samsung thermal protocol?

What rom and kernel are you using ?

edit: On CM10, CM10.1 the battery temp can reach 48C without problem (and the cpu only throttles at 78C). There is not a limit like on Samsung based roms.
[Galaxy S III General] DualJoe:
Why are most people starting with 266MHz GPU (instead of 160MHz)? The 1st step should be the most important one to save power. When you're browsing, reading or doing simple stuff it will mostly reside on that lowest GPU step. I will test 160, 270, 380, 490, 600 later (if it's possible...).

Are the stock cpu values on the first page correct for sure? I thought Siyah would use stock values but they differ from those.
[Galaxy S III General] bala_gamer:
You can try using main status tool on how often the 1st and 2nd stepping of the gpu is used. Setting 1st step to 266 makes things smoother.

[Galaxy S III General] bala_gamer:

I'm running at the following settings which have been fully stable for 2 months now. Siyah 1.8.9 + CM 10.1 (24/01/2013 nightly - I still feel this one has given me the best battery life so far combined with the undervolting). These are the settings I'm on right now:

CPU:

Governor - pegasusq

Max Frequency - 1600 MHz

Min Frequency - 200 MHz

CPU Voltages:

1600 MHz - 1250000 µV

1500 MHz - 1200000 µV

1400 MHz - 1187500 µV

1300 MHz - 1137500 µV

1200 MHz - 1087600 µV

1100 MHz - 1037500 µV

1000 MHz - 987500 µV

900 MHz - 937500 µV

800 MHz - 900000 µV

700 MHz - 875000 µV

600 MHz - 850000 µV

500 MHz - 837500 µV

400 MHz - 812500 µV

300 MHz - 762500 µV

200 MHz - 737500 µV

GPU Steppings:

1st Step - 266 MHz

2nd Step - 350 MHz

3rd Step - 440 MHz

4th Step - 533 MHz

5th Step - 600 MHz

GPU Voltages:

1st Step - 875 mV

2nd Step - 925 mV

3rd Step - 975 mV

4th Step - 1000 mV

5th Step - 1025 mV

The GPU settings aren't anything special, but the CPU undervolting is pretty extreme (more than -125000 microvolts for some steppings). These settings probably won't be 100% stable for most people.
[Galaxy S III General] dsmpampis:
As I can see you have also for cpu undervolting -125mV! I think that one is also extreme. And how about cpu, battery temperature?
