Hi,i'm new here and sorry for my bad english
I'm on PA 3.1 and since PA's base upgraded from 4.2.1 to 4.2.2,my nexus 7's bottom left corner got warm and hot than normal,CPU temperature is usually at 36-37 °C,even when i just browsing/reading
I just want to know if anyone here got the same issue as i got
Thank you and sorry again for my bad grammar
I did the same jump as you from PA 4.2.1 to 4.2.2. I haven't had any heat issues at all. Mind you I have undervolted 50v across the board. It might be a rogue app.

what kernel do you use?
37-38 C is nowhere near to being high (if you are indeed talking about the processor Tj)
The stock kernel does a panic shutdown at 100 C, and rate throttles a little below that. (At the moment I can't remember if that happens at 95C or 90C).
That Tj temperature is measured by a circuit embedded in the face of the SoC chip itself, so it is literally the hottest place in the whole device.
I have run native multithreaded stress test codes simulaneously with OpenGL benchmarks, and while the lower left corner of the tablet gets warm, the maximum Tj I observed was about 85C (Stock kernel - no GPU or CPU OC'ing). When "idle" such as reading web pages, my stock device sits around 38C as well.
The only thing that is disconcerting about what you report is that you mention a warm tablet in conjunction with 38C. That shouldn't be the case unless you made the temperature measurement substantially later that the CPU/GPU load which created the temperature spike.
Remember that there is a substantial delay between a peak temperature felt through the case and when the CPU goes up to high temperature. In my experience, it takes several minutes of maxing out the processor(s) before you start to to notice that "lower left corner" hot spot. So if you are observing that behavior regularly, you do have a reason to be concerned.
good luck

Understood. I should have said "cat /sys/kernel/debug/tegra_thermal/temp_tj" to be clear.
60 C does seem a bit high for a N7 which is supposed to be doing very little work.
Mine (stock jdq39) is sitting here doing nothing but with the screen on (plugged into USB), not charging and it is about 42-43 C.
The effects of heat are cumulative - you should look into it.
So am running classic stability test 2.7, and I've ran this before and my CPU get to 60°C or after like 15 minutes, I ran it today out of sheer curiosity and it started to show 91°C. Am using cm with there kernel since I recently flashed the latest nightly and thought how would it differ from matrixes. Another thing it can be that the values are being incorrectly displayed. Is this something I should worry about? Am really not in the mood for an RMA and losing my phone. Shouldnt of the system shut itself down after a certain limit as a fail safe?

Are you sure it is Celsius and not Fahrenheit? Is about 33 degrees Celsius. At 91 degrees it would have shut down and rebooted a long time before reaching that temperature.
Trickster mod says its °C so?
edit: the device itself gets very very hot which am sure if it was running at 30 it would be fairly cool would it not?

- touch the back, if it's 91C your fingers will know.
- RMA because you run a heavy benchmark test (I never do, no opinion on that) and it -logically- heated up..?

it was very hot I had to put it down so am guessing its 90C, but now its a lot better, it seems it wasn't throttling proper? it attempted to run the entire thing at 1.5ghz constantly, rather than it's usually clocking down to 1.1ghz. Now it's throttling and while its at 78C, it just feels warm and it actually being managed.
I flashed back to matrix's kernel and prefed to use the scaling test which would probably be closer to real life usage and its running 45C. I really like CM and don't want to flash back to stock but I may end up doing it
Note to self
Don't run stability tests

90c will probobly burn your skin.
it was mistake.
Must be a mistake. 91 degrees Celsius is almost 200 Degrees Fahrenheit, that would melt the plastic on the phone, and burn your fingers.

not true. ive forced mine to hit 100C. its the cpu temp, not the temp of the outside of your phone. ive even hit 110C with my galaxy nexus. it doesnt stay at those temps long enough to melt your phone, lol.

stability tests are meant to push your cpu to its limits. pushing the cpu to its limits will create lots of heat. it is meant to do that. if youre using stability tests, you can not complain about heat. its like putting your car in neutral then flooring the gas pedal, itll cause your engine to get hot, especially if you do it for 15 minutes.

safety cpu shutdown for the gnex is 110C. as soon as i saw it hit 110C, it shut down. but you really have to try to get it to that point by stressing it awfully hard. same with the nexus 4, 100C is the safety shutdown. running certain benchmarks or stress tests are the only ways to get it that hot. which is why it makes no sense that someone running a stress test for 15 minutes is complaining about heat, asking if he should rma his device.

I think you are referring to battery temp and not CPU temp. Unless you live somewhere very cold it would be quite difficult for your CPU not to go over 40c

Canada its fkin freezing!! just checked set cpu and its 23 c, but im just scrolling through twitter, not really doing anything else.
The points that I would be concerned with temps are
Battery > 50°C
CPU > 80°C
This is based on stock thermal throttle at 60°C CPU
On Franco kernel I have upped my throttle limit to 70°C so I wouldn't be concerned unless it went above 85.
You will know if your battery is at a dangerous temperature because it will be very uncomfortable to hold

no.
for the record am not asking if I can RMA, am happy with my device and really don't need to lose it for a week. But this just started happening more frequently. Sometimes the thermald ****s up and it doesn't throttle at all, at times I could be just playing GTA, Worms, Plague etc I usually don't notice because the phones down on the table, pick it up and owwwww flashing back to matrix solved the majority of it tbh. Right now it's sitting on 31C idle, it'll be about 40-50C on chrome funnily enough, and then 60ishC on games, pushing 70 depending how long I leave it on. I see that as fairly normal tbh, but 90C? I wouldn't even trust my fan cooled i5 to go there.
And am back were I started just playing 2 minutes of batman and its at 70°C and burning my hand
wow 91° ?? its dangerous maybe your device will " BOOM" sometimes :0

cool.
but yea, its possible to reach those high temps if, and only if, pushing your cpu. itll get warmer faster if your gpu is overclocked(is gpu overclocked in franco kernel?). now, if doing nothing and the phone gets that hot, thats a problem(software or hardware).
nah its not overclocked, atm its cooled down, although it does take a while to drop from a high temp to something low even on idle.
Hi Guys
Basically had two S4's from phones4u, my first was the black mist, which had intermittent faults and in my opinion overheated. This was sent
to Samsung who said that in a nut shell it was fine and the S4's ran warm get over it or words to that affect. As I was unhappy and out of the 28 day return I decided to sell. I was still in love with the S4 so bought another again from phones4u from an ad as an upgrade but I was given the receipt.
This one is the arctic blue version which is really sexy hehe and I love the look, problem is this one seems to also run hot in fact even hotter than the black mist, I was hoping as the blue model was newer Samsung would have identified the heating issues and built the next batches with possibly better thermal compounds or some other way of reducing overheating. This version also occasionally lags and jutters from time to time, I find when on power saving mode they both ran smoother.
My problem is I only have a few days left on the 28 day return so I want to make sure that I havent been that unfortunate to have 2 brand new s4's that are faulty, I know that the s4's run hot and I know that a lot of people are complaining about smoothness, but how hot is the norm and how smooth should they be?? is the question.
I've had loads and loads of phones including, htc one, iphone 5, S3, various windows phones, so I know how smooth smooth should be.
I would like to root and put a custom rom on but I'm holding out to know if this phone is faulty or slightly faulty so to speak, or if everyones S4 is as hot and every so often jerky, I find internet very jerky especially when using chrome browser simple things like scrolling, its not my wifi as my wifes s3 and ipad mini run smooth or smoother.
On Antutu my benchmarks vary from as low as 21000 to as high as 26000?, I know that Samsung is involved in this benchmark rigging thing but surely thats not right?, sometimes I have wifi on dont know if that makes a difference both to benchmarks and heat?.
When I do a stability test, the top half of the screen gets very hot and normally temps start at 30 and rise to around 40 with a gradual increase, as for the stability it goes from 140 to sometimes 70 (3 or 4 times) it also takes around 15% out of my battery for around a 10 min test.
I have attached screens as luck happens the last stability test the phone went to under 40 as you can see, I charged the battery left it a while then ran the test fresh, please can you run the stability test on your s4's guys and put my mind at rest or help me prove to phones4u my phones running hot.
My firmware is UBMGA - i9505
Many thanks

Of course s4 is hot when you use processor a lot or when you recharge s4. Mine hasnt ever become uncomfortable hot but it is warm. Antutu score doesnt mean anything because everybody has different apps running and so on. You had two s4 and it is almost impossible that both of the phones has problems. Remember that s4 is very powerfull and it is very tight package so it is normal if its hot.

My SGS4 is always hot during playing games. Sometimes extremly hot. I've sent it back for warranty repair but they said it's ok. So no luck.
S4 is hot
its hotter than S3 i used to have. It says 1.9Ghz but in games or benches its sometimes lower even than 1.5Ghz because of thermal throttling... when i used 1.5Ghz as max in setcpu i had better results in 3dmark! yep! and antutu score become stable - a bit lower but stable, with 1.9Ghz i had 24000-25600. with 1.5Ghz i had 24300 almost every time.
But now im using UV kernel and i UV -0,50V and i set thermal throttling temp to 90'C, now my antutu score became almost stable at ~26100
I think samsung overclocked this S600 to much... 1.5Ghz is almost stable but 1.9Ghz is definitly not.
Hello guys, well i've read every single post about the phone's working temperature on the forum but i just can't figure if my phone is working fine or not, because mostly everyone on the post refer to the temperature as "warm" "bit hot" etc, which is very subjective. I'm a bit worried because my phone (D806, running stock ROM) gets quite warm after like 20 mins of surfing the web through wifi, or after chatting a bit on whatsapp. By "a bit warm" i mean between 32-34 deg centigrade, refering to battery temperature of course. Now, after reading everything i can't figure out if this is a normal temp for this phone or not. I can also say that the min temperature i could measure (with just cell radio on, in idle state) was 25 degrees. The max temperature i could reach (running antutu for like 4 times one after another) was 45 degrees. Now, i'm confused because someone in a post said the max temperature he got was 34 degress, and his usual temp was 24 degrees. I couldn't even get 24 with the phone completely idle. So, i'd like to know your experience, since i can still exchange my phone for a new one if it's defective. Thanks in advance.
Hi,
There is nothing wrong with your battery temp. You can also check you CPU temp (nope, maybe you will have scared )... Fortunately you didn't saw your CPU temp during your 4 Antutu runs...
The temperature (CPU or battery) depends of your room temperature and your current use. You said yourself with 4 Antutu runs the temperature increase, nothing abnormal even for the battery..., same thing after browsing for 20 minutes even in wifi.
A guy had 24°C battery temp in idle and 34°C max, well, what was the room temperature? Nothing running in background? What he was doing?
I mean even in idle, screen off, your phone can do a lot of things especially if you have a rogue app keeping the CPU busy so there could be a little more heat.
In any case there is a thermal protection (thermal throttling) to prevent damages in case of "overheating" for both CPU and battery the CPU freq decrease according to the temp. Even the screen brightness can be automatically lowered. In last case the phone shutdown if a high temperature is reached (about 100 °C for the CPU). The max battery temp should be about 50°C, I don't remember exactly.
Don't worry, as you reported there is nothing wrong with your tempetatures... Same thing if you take a look at your CPU temp, can be arround 70°C in heavy use, even a bit more in really heavy use.
We have a quadcore device running at 2.26 Ghz, all is enclosed without thermal cooling... it's normal to have "heat" with all the components.
Use your phone and profit, no need to monitoring each minutes your temperatures. You confused yourself by only reading the °C, not how or why it is compared to the other posts you read. Each user have different room temperature, use, settings, etc... you can't have the same temperature as xx user. An average yes, I agree and here you are in the good average...

Guys,thanks for your responses. I still don't get something tho because one of you said that my temp is normal (about 32 deg. while browsing), but then you say that anything over 30 deg should be avoided, then i don't quite understand. My phone gets between 30 and 35 deg while regular browsing, it's mostly a bit over 30 all the time i'm actually using it, SO, that's wrong or not? That's the part i don't quite understand.
I guess vPro97 made a typo or he was sarcastic?
Over 30°C for the battery temp is not dangerous at all, about 45°C also. Imagine people living in a really warm country when they use their phones...
Don't worry, already said, there is absolutely nothing abnormal with your temperatures, nothing... all is fine regarding your use...
Don't panic

Hi.
Question for Mahdi ROM users on the LG G2:
Coming from this thread, I'd like to know how Mahdi ROM's temperature is when you do intensive tasks, like playing games, running benchmarks etc. Does the device get hot? If possible, tell the temperature, what you were running, for how long, did the screen remain on etc.
Thanks.

Anytime you run an intensive game or the like your phone will get warm, no matter what phone it is. Benchmarks get warm too, however I find those to be useless.
It isnt useless, he's collecting informations about the black lines from a few roms...at least be happy that we have such guy on our G2 section, who is willing to help out as much as he can..

Hot as in "it shouldn't be at this temperature at all while doing what it's doing".
So that means 39°C tops. That's a bit above human normal body temperature. Not bad.
If I remember well, playing Plants vs Zombies 2 gave me 47°C tops in GSAM Battery Monitor, without ever rebooting.
Thanks.
Compass.
yeah max I had was 50°C, but not very long.
I guess it can shoot up higher, but for usually when doing intensive stuff, its about 39. Not to bad.
was one build it was 42 also in rest. That wasn't to long though. pretty cool, new build and fixed haha
@Compass Linux - my device gets extremely hot on any aosp rom even on normal usage, like web browsing, texting, checking emails and reading certain articles on the web, the cpu temp ranges from 50*C-60*C at times even 70*C and it gets throttled down as i set my tmep trottle at 70*C.
battery temps range between 27*C to 43*C which is NOT normal so im no longer on any aosp roms. it scares me as for lithium batteries temps above 35*C is bad for its life. also none of these temps are good for the phone so now im on pardus hd 7.1 and my cpu temps are within the rage of 35-50*C and battery temps from 32-35 under the tasks which i mentioned earlier.

If it was bad for the CPU why would it come from the factory to start throttling at 75?
I think you're mixing your views of desktop CPUs on to SOCs.
SOC (system on a chip) are crested to be passively cooled.
For this phone 30~50 idle/light tasks and unto 75c underload is perfectly normal and safe.
