[Info]Monitoring cpu temperature of S3 is now possible - Galaxy S III General

Hi guys,
am just happy to share the news that "monitoring cpu temperature" now works on s3 with custom kernels.(not tested with stock)
a big thanks to @viking37 here for finding this
How to?
install system tuner pro along with notification package and enable it in settings to monitor the temperature on notification bar.
alternatively you can also use system tuner pro widgets to monitor it on your homescreen.
edit:
temp monitoring seems to be working with all kernels!

Thank you for this find
First CPU temp limit before thermal throttling is at 80°C then thermal throttling is stopped when the CPU reached a temp of 78°C...
And the max temp that the CPU can handle is 120°C before a kernel panic so I presume the CPU shutdown?
While benchmarking at 1.4Ghz, no overheat:
63°C... There is still room before the first thermal throttling. And this is at the end of the bench (just a custom bench for the CPU)... I will do some tests at higher CPU freqs for see...
I think that this CPU does not heat that much.

hehe the excitement made you all forget to suggest apps for the rest of the forumers.

System Tuner pro: https://play.google.com/store/apps/...her#?t=W251bGwsMSwxLDYsImNjYzcxLnBtdy5wcm8iXQ..
System Tuner "free": https://play.google.com/store/apps/...eloper#?t=W251bGwsMSwxLDEwMiwiY2NjNzEucG13Il0.
Maybe there are other apps, I have not tested or searched yet...
I put the start of the discussion about the CPU temp from SiyahKernel's thread: http://forum.xda-developers.com/showthread.php?t=1709686&page=324 (from the middle of the page then the next pages).
As suggested by bala_gamer it would be great to know if the other custom kernels support it, it would be interesting to know.

@ viking
most of the other apps in play store is not working. already tried it.

Good find viking37, been waiting for this for ages!
Glad to see bala made a thread for you and your discovery....

Stressing the cpu for 3+ mins with stress cpu @ 1.5 ghz with uv bumps the temp upto 77c whereas 80 c is the throttle point.
《tapatalked from galaxy s3》

Bala I'm quoting your post with the throttle temps and playing it in that CPU heat thread from a day or so ago, I think some people need to be educated about what a CPU can do.
Can't believe the cut off for this CPU is 120c, that's unbelievable.

120c is insane.
AndreiLux pointed me to the file which had these settings. Have requested him to throw some more info on these throttle values, hopefully he does it once he comes back from vacation.
My question is if the cpu starts throttling down at 80c then how come it will reach such high temps?

That's a good question, my only guess is say you are using the phone heavily and your CPU temp is around 75c, then you do something very CPU intensive like a bench or stress test, it may cause the temp to jump quite rapidly to say 100c for a second before getting hit with throttle 2 @ 200mhz, if you only creep past 80c then you only get hit with throttle 1 @ 800mhz.
CPU temperatures fluctuate rapidly so going from 35-65 is only a second which means 65-95 is the same, plus the more heat already there the easier is is to generate more.

It seems to work with harunjo's GalaxSih 3.5 kernel, so I imagine it would work with stock, too.
You can check the temperature in the terminal or over ADB by doing;
Code:
cat /sys/devices/platform/s5p-tmu/temperature

Overclock widget = placebo

The system already dynamically clocks the CPU
Don't believe? Install OSMonitor and look at the "Misc" tab
Notice the "ondemand" governor scaling the processor from 245000 - 998400 hZ
Leads me to believe CPU governing is already in the kernel
You might be right.
The only difference I can think of is with the widget people are using (I have not tried it) the under clocking happens the instant the screen turns off. Where as we have no idea when/how the standard under clocking happens, if it does at all.
I am waiting it out. If the under clocking widget is true, it will eventually become common knowledge on these forums. For now I have not seen anything that has convinced me and I fear if i tried it I would suffer from the placebo effect. The last thing I want is another app running in the background for no reason.

I've noticed this as well. System Panel measures my CPU speed at around 245 Mhz when I'm just swiping through the home screen, but cranks up to 1 Ghz when the CPU usage approaches 100%.

Really? I wonder if that could explain some of the choppiness while scrolling around and general phone use.
I can confirm this with SetCPU's real time monitor. drops to 245 when not in use, and 1ghz when scrolling around
I think oc widget is better. I can choose a 5sec interval in which it checks to see if there are processes that need more CPU power.
I wonder what the intervals are in the stock unrooted OS
Oc widget def works for me, and I'm not just letting my phone sit as a paperweight, I'm using moderate to heavy everyday and the results for me are better.
Also, does the unrooted OS allow other frequencies besides 245 and 1ghz?
Oc widget runs mine in the 300s 500s 700s and 800s when needed
1ghz is not needed all he time when the screen is on. And I don't notice extra lag anywhere
And with 5sec intervals, the screen does not have be off to see 245. Just let it idle for 5 secs
I don't even think the OCwidget works. I mean it tries to set new values, and it thinks they succeed, but I think the new values are ignored by the kernel. For example, I tried to set min and max to 250 mHz and it still shot up to 1 GHz.
My apologies for being a debbie downer.
Here you go... can someone produce something similar with the stock OS unrooted
it does help.. even tho you see my battery between 81 and 79 lol... for me, the top 25% of battery life (from 100-75) goes by fast no matter what, but then it really holds good life afterwards.

The problem is we are all in the "i think" stage, so its pure speculation. Maybe the oc widget developer could help us out here.
I Do think the op should put a ? In the thread title to get more discussion on this, cuz there are some brilliant minds here at xda
Edit: I emailed the dev w this thread asking for his insite, hopefully he jumps in
Faith is a powerful force
if overclock widget really controlled the clock
1) Linpack scores would reflect that
2) mHz readings would reflect that
But... they don't

How do you figure a problem? 998mhz is max.. u just poking fun at "hz"? lol
So with OSMonitor, do you see any current values besides 245 and 998?
here's mine with OC Widget and some of my defined frequencies... If it truly fluctuates to differents clocks like mine on the stock OS with NO root (please show screenies), i will resign as the OC Widget evo underclock believer until an overclock kernel is released and camera works .
I'm on stock OS with root
It indeed goes to all the freq's
sorry too lazy to screenshot
EDIT: oh and I uninstalled OC widget!

That would be 998 millihertz which would be even slower.
I may seem like I'm being pedantic and I wouldn't even mention it if this forum was for arguing about American Idol winners but this forum is by definition populated by geeks and otherwise smart individuals.
Regardless of what the app displays, the phone is operating at 245MHz to 998MHz. The capitalization of the H is official but I'm not that anal. Capitalizing the M means mega (1000000). Lower case means milli (1/1000).

ROFL!
email from OC Widget dev
here is what the dev (Billy Cui) wrote back to me about OC Widget and the Evo...
"Yes, most system support dynamically clocking, but you will still
benefit on using OCW, especially for save battery. And some system do
not running cpu full speed, and with OCW, you can force it run faster."
Makes sense, like i said about the update interval being adjusted with OCWidget.

Overclocking >806?

Okay, so i was browsing through the results of the Antutu benchmarking application, and I saw this guy, he had a CPU freq of 844 freq. Is that even possible? Just wondering
for reference, hes number is 887243
It is possible, within 5 or 10 minutes. As soon as the run game, the phone goes to restart (((

Overclocking the phone to even 787Mhz makes it quite unstable. That's why clock speeds above 806Mhz are not included in most kernels...but even if you do somehow overclock to 844Mhz I don't think the phone would survive for more than 15- 30 mins not to mention lots of heating up. In short-such speeds are not feasible for daily usage

If he's really hardcore, maybe he opened it up and used a fan or something.
Like the other ones written bevor me. Overclocking the O1 above 786 Mhz are like Gambling. Every CPU are a litle bit Unique, so nobody knows what kind of Frequency youre once are able to handle.
For Exemple iam running myone stable @ 320/787. But every Step Higher will be results in FCs and Reboots.
So the only way to go is to OC youre Phone step by step to find out what kind of Frequency youre CPU can handle
I once accidentally left my phone on 787mhz performance after benchmarking, and after a few days my phone crashed and would not boot into android, scared the **** out of me, but after about 10 mins it was fine, i quickly found out why this happened after. Overclocking your phone to 787mhz adds a lot of extra heat to your phone, and unless you live in a freezer or Antarctica and never keep your phone in your pockets I would not recommend over-clocking it that high.
If your new to the whole overclocking things, youtube extreme overclockers and you will realise would needs to be done to cpus to overcome the excessive heat.

Overclock problem

I am running on carbon rom with moltley kernel. I set the max cpu clock at 1674mhz using antutu cpu mastaer. I use cpu spy the watch the cpu frequence, it do can go up to 1674. Then I run my phone with antutu benchmark. the result shows that my cpu frequency is 1512mhz only. and then, I check the cpu spy and cpu master again, the max cpu frequency has underclock to 1512mhz. But why it happens? I have set it to 1674 before, why It will automatically lower down after I run antutu? thx

Check this, even I didn't over clock and didn't touch anything, it down clock to 1296mhz instead of 1512mhz as default
is it the rom problem or kernel problem?

you probably neex to update your busybox. download the free busybox app by stericson from the play store, install it. open it, let it do its thing, press smart install. after, try antutu again, with your cpu speed.

ahhh.. yea, heat throttle will do that. you can turn off heat throttle(or use a kernel that raised the heat throttle temp, like trinity). to turn off heat throttle via terminal emulator..
su(press enter)
echo N > /sys/module/msm_thermal/parameters/enabled(press enter)
to turn it back on, replace the N with a Y.
But the thermal throttle has already set to N before I setting it.

Nexus CPU Temperature

Hello guys..
People have reported that nexus 4 gets too hot, too warm...but too does not say any number..
Lets talk about numbers here
After normal use (facebook,gmail, light apps) for 30 mins my CPU temp is 49-50 (Celsius)
After playing Need for speed most wanted for 30 mins my CPU temp is 62-64 (Celsius)
After talking on phone for 30-40 mins my CPU temp is 52-54 (Celsius)
My average CPU temp is 50 (Celsius)
is it normal....?? or should i be worried..
It feels a little uncomfortable while holding it at 60 (Celsius) will a case help me in feeling more comfortable )
What is it for you guys..??
I believe the temperature limit is 70 degrees, or that just might be trickster mod or my motley kernel.

Hi,
Stock or custom kernel? What CPU settings?
Your temperature seems normal to me, just this one seems to high for me:

Maybe you are in a place with bad signal? What is the room temperature?
After 30 mins of call my CPU temp is about 40°C...
But, average CPU temp 50°C... it's high unless heavy use yes, is it an app who calculated that?
In idle (after 15 / 20 mins) what is your CPU temp? Maybe a rogue app in the background who use your CPU
Maybe a case will be more comfortable for you but it keeps more heat...

Your temperature seems normal to me, just this one seems to high for me:
Maybe you are in a place with bad signal? What is the room temperature?
After 30 mins of call my CPU temp is about 40°C...
But, average CPU temp 50°C... it's high unless heavy use yes, is it an app who calculated that?
In idle (after 15 / 20 mins) what is your CPU temp? Maybe a rogue app in the background who use your CPU
Maybe a case will be more comfortable for you but it keeps more heat...

Thanks for the reply man
I am on stock kernel..have not rooted yet
Ya cell reception is bad in my area so it may be high..after 15-20 idle mins my cpu temp is 43-44 (Celsius)
I maself calculated average..i am not quite sure about the average though
Can u please tell me how can i find out if there is any rogue app in background causing CUP temp to increase..?
There are 3 options to reduce the temperature:
- open your phone and place a copper plate http://forum.xda-developers.com/showthread.php?t=2144652
- try a task/process manager/monitor from the Playstore to find active background apps (I don't think it will really help...)
- or root your phone and edit the file "thermald.conf" in system/etc/
I didn't open my phone, it's a bit risky, so I modified the " thermald.conf" file.

Here is shown at which temperature your phone limits its speeds (found at youtube)
http://youtu.be/abf7nPiUUE8
And I've also placed a modified "thermald.conf"-file where the temp. limit is set at 31°C (°C always means the battery-temps - not cpu!)
at 31°C: limits the cpu from 1.5GHz to 1.2GHz, gpu full speed (400MHz)
at 35°C: cpu stays at 1.2GHz, limits gpu from 400MHz to 325MHz
...
at 39°C: cpu to 1.1GHz, gpu to 200MHz, lcd display brightness reduced
...
at 45°C: all limited (same value than orig. file has)
If you modify the file, don't forget permissions: -rw-r--r--
hope I could help
Can someone explain this overheating paranoia? I'm not being a ****, I just really don't get it. I've seen my GPU on my computer hit 90* and its fine. Most processors are rated for temperatures way higher than 60*C, so why is everyone freaking out about 60*? Of course the phone will get warm, its a pocket sized computer with a dedicated graphics chip.

Help, please participate. Do I have a bad hot CPU?

Ok guys I need some help from the community to see if my phone is really defective or not. My issue is, my phone is throttling almost immediately, reguardless of temp (55-63c) range in benchmarks and stress tests, now when I go and force off throttling through intellitemp, when I stress test at above 1.4Ghz, the phone will reboot in a matter of 10 or so seconds. This is after flashing dori kernel 4.4, and I've tried clearing cache/dalvik, reflashing, going back to stock kernel then flashing again, etc...
This is all stock values, with exception of forcing off throttling.
Temps max out around 67c and throttle down at 65c
And it hovers around 45-55c with normal usage. Which seems high to me. But I'm new to high powered cell phones.
So I want everyone who's willing to participate to get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.
This will at least give us an idea if our phones are operating to spec temp wise and see if I have a faulty hot phone! Please help prevent me from dealing with T-Mo warranty replacement if I don't need to

I tried it out with my d800 stock and after first few seconds it doesn't go any higher than around 1.7 and remains on lower speeds so I think that's the way the app does it's computing

Cool, im going to test out antutus stress test now to see if the same thing happens.
Sent from my LG-D801
Antutu was bust, didn't really show me a thing. If incan just get a couple more people to try this, then I'll at least be able to chalk it up to not being my hardware.

Same here it's the throttling and it reboots if the max temparatuere comes.

Your voltages are probably to low. I had same problem adjusted up my voltages at the high end 1512 and up and it fixed it. Also could be kernel issue

No they aren't to low because 2.8 GHz works fine.

My temps don't go over 83c while stress testing, max shut down temp should be 120c from what I've read. So I assumed its not a thermal issue. Am I correct?
Hopefully some more people come through and help me figure this out.

I've tried both Dori and dr87's kernels. Both show the same issue.
Sent from my LG-D801
Something isn't right for sure, I just set the core voltage for 2.2 to the voltage that 2.8 has and ran a stress test locked on that frequency only and it rebooted still. I'm seriously starting to think I have a bad chip.
It can't possibly need that much voltage.

What was the max temp you saw it hit?

Here are my results. Hope this is helpful. I had no reboot.

Hate to be the bearer of bad news but I have been having issues with this phone since I got it. Should have picked up the Note 3 instead. This phone has serious thermal design issues. The instant all four cores come online at 2.3 GHz temp starts rising above 60. Slowly the phone throttles to about 1.3 GHz. It is very noticeable in games, even playing for 5 minutes and the game starts to feel sluggish due to throttling.

Maybe if you try undervolting a litlle, really helps get the temp down.
2265MHs @ 965 mV
oc: 2496MHs @ 1000mV (Stable)
check whats using cpu, enable development settings, then in development settings there is an option that shows whats utilizimg cpu. Could be a process that has gone astray.
usually clean install without recovering apps data does the trick. Dont ever recover system stuff.
my test :

From the testing I've been doing this is correct. Its more as if it was designed for the max clocks to be a turbo mode. For quickly taking on small procedures, while sustaining 1.7-1.9ghz for major tasks.

I've been experimenting as well with UV.. It does make a difference. But sadly it still hits the throttling threshold.
