[Q] Cpu thermals (80c) - Galaxy S III Q&A, Help & Troubleshooting

Ive had my Galaxy for a while now but lately i have felt it get hotter, and downclocking while gaming.
Ive tried stress testing my phone at 1.6ghz with a voltage of 1250000mv for under 5 min, and cpu temps skyrocket to 80 from idle of 45-50
I have sent my phone in for repair of the home button a couple of times where they changed the whole screen and bezzel.
The question is could they have screwd up the themal pad/paste if the galaxy s iii even has one?
And what kind of temps are "normal" under 100% load?

You mean like cpu + thermal Block _ heat sink + fan .

Wow, thats really hot! The s3 indeed has an thermal pad (on this video, fast forward to
4:00) its the spot thats covered in blue. For me the temps have always maxed at 50-60c

Sling a steak on for me too :thumbup::thumbup:

So what do you guys suggest, should i try to open it up and fix it myself.. or send it in again?

Well for a start remove all kernel tweaks and see how it performs as its meant too. See what normal usage results you get......let's face it, you overclock it, then run a stress test, it's bound to get quite hot!

It shouldnt get 30c hotter with 200 mhz... and using less voltage then 1.4 stock did, so thats kinda pointless

Depends on his chip, what other tweaks he has done etc etc, so yes, it entirely has a point....he wants to know if they messed up the repair, and the only way to test that is run stock......what do you think they will say in the repair centre when he walks in and says it got hot when overclocking and stress testing

Same result with stock... screw it im gonna send it back and ask for a new white model... :silly:

Battery drain+Heat=Wifi+Stock Browser, please read

Hello again dear xda members
I've been using S II for over 2 weeks now! I get the following(which many of you do get also). When I turn on WiFi and start surfing, the phone starts to overheat and battery is drained like a juice.
Well, after a long study, I've found out that it's the stock browser's fault!
Yeah! I opened WiFi, surfed a little and it started to heat up! Well, I was trying to download something, and since stock sucks at downloading( except if you add to it an app from the market called Downloadfiles) I opened DolphinHD!!
What I saw, or felt-whatever-, was just
After 5 minutes, the phone cooled down, temperature became normal and of course battery was less consumed!
So, to all people who have heat issues, it turns out(at least in my humble opinion) that it's the stock browser's fault!!!
Any thoughts anyone? Similar experiences?
I've been using it for 10 days and experienced no such overheating, but battery time should be much better.

Really? It doesn't overheat never? even not when playing games?
I thought mine was faulty, but I went to couple of stores where they have it open for customers to play with, and I did the same as mine and it started to heat up!
Mine heats up a bit after playing a game or running a certain app for a while, but I never experience overheating with the stock browser. Though you should take in to consideration that the GS2 is a thin device, the CPU is close to your hands. Most phones also have to exessivly keep searching for connections because it is weak or something is blocking its way. The transmitting/receiving device is located at the top along with the CPU so it'll tend to get hot. Most smartphones do overall.
Also, the phone gets hotter while using it connected to a charger just because the battery is filling up the same time you are using it. Also, take in to consideration that no patch for true dualcore support has yet been released nor announced. Just some factors why the phone heats up.
thanks man!
Well, heating up is normal-as far as I read in here-... But when using Stock Browser, I'm talking about overheat! really! I believe it's a bug, since as said, nor Firefox, Dolphin and Skyfire(I use all of them) produce that issue! And I disabled flash content(thought that might make it better) but it was the same! Don't know!
Anyways, thanks for answering!
OVer wifi I have no problems. Over 3G is another story! and playing games is another story. It warms up every 5 minutes while playing games.
Yours too huh? well, mine does that on WiFi!
What is Overheating? How do you know it is overheating unless you know the temperature of the battery? Well OP and other posters who are saying the phone gets overheated please mention the temperature of it. The ambient temp of Europe/USA is 20-25°C Max, and if the device runs even cool then it will have temp around 30-32°C, that is much higher than the ambient temp and probably that's why you guys are feeling the phone is overheating but in fact it's not. Here in Calcutta, ambient is 32-33°C and the Phone temp in normal is the same, so we/I don't feel it's overheating, only when I surf net for an hour straight with charging then the temp rises up to 44-45°C, that's when it could be said that the phone is running on high temp, still for the hardware we are given 45°C is not hot.
So before saying the phone is overheating please check the battery temp.
Regards.
how do I measure battery temperature?
Ok, Battery life widget?
I'll measure then I'll let you know!
There is a reason stock browser uses more battery and heats more. It uses GPU to render pages more quickly! But for me even on stock it is not that hot, more than on other phones, but thats what you get for a thin phone.
Maybe somone will test battery life with stock+GPU and dolphin browser with no GPU. Maybe the difference is not that big at all, maybe just GPU heats more than CPU but uses same battery.
now let's not forget android doesn't have graphics acceleration, and without it the GPU has to work harder which generates more heat

Ok, I get 41 to 45 °C degrees!
So, no overheat just heat!
So, based on what you're saying, this is normal?

Your ambient is 27°C, right? So it's normal to me. Anything less than 50°C should be OK, imo.
Regards.
My ambient is 34 to 30 °C
Ok, so my phone is fine? Wow! !! thanks
that really made me happy!
I thought it was faulty
Thanks so much everyone for answering

Summer in Greece and sub-30-degrees Celsius don't go together.That's why we're hot!
Anyway,****ty joking aside,inside a bus today,under the sun with an ambient temperature of about 35-36 degrees(dunno how you put the degrees symbol pal ) and with my GPU overclocked at 400MHz with 1100mV using tegrak overclock ultimate,I played some Angry Birds and,although the phone reported no more than 44 degrees,it was very hot at the top.
My opinion?If you(or me obviously) manage to somehow burn/fry something,make sure to do it so bad that it doesn't even respond to Chuck Norris' roundhouse kick! That way maybe Sammy won't notice...Shush!

[Q] Battery getting too hot ~40'c!!!

Hi.. I m having this problem from months.. But is it normal? My phone charges and after 15 minutes the geeko heats up to 40'C.. Is it common for all.. Just asking before taking the gizmo to service center...

Its not, the MAX temperature of a phone Li-ion battery seams to be 60° C
mine is constantly 25~40 (MAX)
And high levels shorten battery life until next charge
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures

Thanks all for replying
Casings too will raise your temp, I had a cheap case I got with Koodo, and it kept all the heat in the phone, I removed it and my battery temps go down. although I keep it on when it's not charging. It's fine then.
My Galaxy Ace is always at 45 degrees......unless it was a miracle and the air-conditioner managed to cool it down

No I don't care if you're anti-Apple.
I never saw my cell going to 45'C.!!! One interesting thing i noticied is that the temp is only high between 20-70% battery charging.. After that just 2-4 minutes temp goes to 30'C!! While gaming upto 35'C.. Only charging heats up my gizmo.. Never had this problem with NOKIA 5230..
My battery once had a temperature of 50 degrees
Sometimes, it also depends on how much you're stressing the CPU. If you're doing something heavy like a lot of multi tasking or 3D gaming, it'll heat up the battery and such. Just like using your phone while charging. Happened to me a lot before so I stopped that habit.
I use SetCPU to slow down Max CPU Frequency to 480 Hz when phone temp goes >40 C. That helped.

I use 480Mhz because more continuous CPU cycles can definitely heat up the phone. This is why any phone heats up quickly when using it and charging it simultaneously. My phone temp has never gone beyond 40C. But I would start worrying and would not use it when its charging, if it'd gone beyond 40C.
And no offense, but those who say like 60C is normal. You guys are definitely hampering your battery life.

How does one disable thermal throttle

I am running on a kernel and am getting reboots when the device gets too hot. Any scripts for me to run?

disabling thermal throttle will permanently damage your processor, its specifically meant to safeguard the processor from higher temperature that it cant handle. u have to change it at the time of kernel compilation if you still need a fried cpu

There is absolutely no way you are getting reboots because your device is too hot.
It gets throttled at 80c first, then at 90 or 100 and doesn't switch off til 120c.
There's no way you are hitting 120c.
Your reboots are due to something else.

Hold a cell phone - anything, actually - that is at 120ºC is pretty much a lot worse than sticking your hand into boiling water: you'd have terrible burns.
Are you using the phone on a very humid, wet environment?

That doesn't apply, it isn't the phone that is 120c, its the CPU.
I held my galaxy nexus as it shut down because it hit 110c, I didn't get burnt.

you are wrong
TTC does not read temps its guessing the temp and it guessing it so wrong.
try to cool down your S3 and run a stability test then run the same test without cooling.
check the CPU speed with CPUspy.
TTC kicks in at the same time even if you cool your device down or not.
TTC has nothing to do with real world temps!
i have a Nexus 10 and i must take this ugly bug out of the tablet.
it stinks!
anyone knows how to disable Thermal Throttling Control or higher the limit?
it must be the same settings for every samsung device.

Is it supposed to work the same way for both of them? As far as I know nexus 10 doesn't have a temperature sensor, is that the same case with, S3?

[Q] Phone overheating when using google maps for navigation?

I have a fascinate currently running HellyBean 4.03 and I have an anker 1800mah battery, I have the kernal running smartassv2 and sio with max cpu set to 1200. I used gmaps with navigation (gps plus cell data) last night for about 30 minutes and when I picked my phone up again it was hot. After turning everything off the phone cooled down again but I am curious what would have caused this? Rom? Kernal? Battery? Anyone else experiencing any overheating issues?
I would test the battery myself but unfortunately I cannot get to my original battery until this weekend.
Yeah, that always happens when it has to run at max or near-max clock frequency for a long period of time. As long as it isn't give-you-a-burn hot, nothing is wrong.

If this is normal then is there anything I could do to reduce the temperature? Maybe set max cpu back to 1000? I only ask because I am concerned if I tried to use navigation for a longer period of time the heat would end up causing some damage to the phone.

No its fine these phones are known for getting a little warm I have mine set to 1.4ghz 24/7 and its fine . back in the days when you could over clock your phone to 1.7ghz LOL I had my over clocked to 1.6ghz and it got so hot it would turn on and off it never hurt it lol

Benchmarks

Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:
