Hi,
I'm using a Canadian Galaxy S4, SGH-I337M.
Rooted, running on Liquidsmooth 4.4.4 ROM. Also has Ktoonsez kernel. It is currently undervolted+underclock a bit, and is stable (I could overclock it, but I don't. No need).
Been wondering for a long time about the operating CPU temperatures of the Galaxy S4... Never had the possibility to do testing with CPU temperatures before. I do have a LG P500 that I have overclocked a ton in the past, still work just fine, but the LG P500 is old and do not support viewing CPU temperature, so it's my first time experimenting with that.
How hot would be too hot for this phone? There are several opinions, but never figured out if I... "minimize" the risks of my actual temperatures, for some reason. My laptop CPU throttle at 85 celcius for instance. While it's a phone, it's completely different.
At night, while connected to charger, it would be pretty cool, at 25-30 degrees when I wake up;
I would say that most of the time, my CPU is running at 50 celsius, and rarely ever exceed 65-70 under normal use, or even gaming. Plus, the CPU is undervolted and a bit underclock, so I do feel like it run cooler than usual.
Quoting Meowmix from Rogers forums:
It varies on the usage of everyone else & how you handle the phone ( cases & such). Also if you are in extreme heat or having the device in direct sunlight.

So, the case does matter? I do have that Otterbox case which is pretty tight and enclose the phone pretty well, I would believe that the phone would get less.. air.. but I mean, it's just a case, didn't thought it would affect much..?
Quoting Ahmed from AndroidCentral Forums, I would say that I have a quite similar situation.
No, just when i ran AnTutu when it runs the 4 cores at the maximum frequency the temperature is between 80-91c, and at normal use while surfing the internet the temp. 45-55c and the battery reaches 38c after an hour of continuous using.

I CAN reach 80-90 celsius, but only if I really want it to happen. 38 celsius for the battery is also correct, I never exceeded 41 degrees yet, on any Android phone (I don't know the dangerous battery temps.. But when I reach 40 degrees I try to put it down as fast as possible). With benchmarks, usually at the max frequency, or testing my undervolt with Stability Test, I CAN reach 80-90 celsius, which look really high. Additionally, I would remind that I don't overclock, and the CPU is undervolted so seems a bit cooler.
So on AndroidCentral, this is the reply Ahmed got, from "CR6" user:
I had to use my temp converter to look up & convert them to Fahrenheit. 80-91c equates to 176-195 Fahrenheit and that's extremely dangerous. These temps will not only physically burn you, but will fry your phone if you continue using it at these temperatures. 45-55c equates to 113-131 degrees Fahrenheit, and that is normal under really heavy usage. Optimally, you'd like to keep it at 38-45c. You may have a defective device if you regularly see temps over 80c and I would advise checking on a replacement.

THAT dangerous? Well, I don't phisically feel the heat - I do feel it, but since I have that phone case, that doesn't hurt at all. But like I mentionned, I never reach 80 celcius or more unless doing benchmarks. Usually I never exceed 65-70. But still it left me wondering - Why does Android allow such high temperatures in first place? Isn't the system suppose to shut down at some point in case of danger, and when?
I've also experimented with thermal throttling in the Ktoonsez kernel, and the throttling values of the ROMs. Touchwiz Stock ROM with DVFS disabled, seems to throttle at 80 celsius, look decent. Liquidsmooth AOSP ROM, stock kernel, does not seem to throttle at all (Huh)! Once, and that was exceptionnal, I've reached 100 CELSIUS using Wifi, connect to a charger after like 2 hours, room temperature was very warm, was not surprised, but when I noticed I reached 100 CELSISUS, I was WOAW, I should shut down. I did reached 100 degrees again, using Stability Test at max frequency after a few minutes. Needless to say I manually stopped the test, because I had no idea how much heat the phone could handle...
So been aware of this, "Ktweaker" app, for the Ktoonsez kernel I use now, does have a thermal throttling option, but I wondering which thermal value should I enter for best "performance"? Default was 70 degrees, I set mine at 80, I've heard of people even putting 90 for the same kernel. Besides, maybe I worry about it too much, because in no way the phone should exceed 70 degrees celcius under normal use anyway, or even gaming. Only way to reach insane temperatures would be benchmarking/stress testing...
Still, first time seeing these CPU temperatures also. I've overclocked my LG P500 several times in the past, dealing sometimes with random reboot, so make stability/overheating questionnable, but the device did not supported seeing the actual CPU temp. So I don't know which temperatures would be considered normal - probably, nothing above 75-80, correct (For the Galaxy S4, actually)?

I do know it can run up to about 180 before hitting critical and shutting down
Edit: its about a 75 degree ambient temp where im at.

At which point is the device supposed to shut down? Is that in the kernel or a hardware CPU trigger? Because heck, I've reached 100 degrees 2 times, I mean, how far/close was I from a shut down? I'm quite surprised.
I've also read of people complaining of S4 overheating, especially maybe after it was released - It's possible that it heats up more than other phones, but honnestly I have no idea.
Thanks for your answer =)
Going thru this exact same thing. Same temps. This is not normal. Mines just started happening one day. Idk how or exactly when

Thank you for your answer;
Used to think some temps look normal to me - Besides, since I've undervolted last week, it's stable and run cooler, maybe better battery as well. I never can exceed 70 degrees even when gaming I supose..
I can reach 80 degrees, but only when benchmarking or stability testing, so I'm not worried, but I do wonder;
I've reached 100 degrees 2 times, once while doing a stability test at 1,89 GHz for like 5 minutes (or more), I had to manually stop. And last time was long ago, watched YouTube videos in bed, like under covers ha, maybe as well connected to charger. Not even surprised I've reach such temps after a while in such conditions, under covers, just no air (Used to do it with my LG P500 too. While I never was able to see the CPU temps on this device. Even then, LG P500 still works, but guessing build quality was much better). Needless to say I was like WOAW when I've noticed 100 degrees, and just put the phone down. Probably went from 80 to 100 quickly, didn't noticed that fast. But yeah, that 100 degrees was.. almost expected under such conditions.
I just really wonder about thermal throttling. Like I've mentionned, stock Touchwiz with DVSF disabled seems to throttle at 80, while KTweaker app for a different AOSP kernel have the default temp limit set to 70. Liquidsmooth ROM, AOSP, does not seem to have a throttling point, since I've reached 100 degrees 2 times with it (Don't intend to test 100 degrees again, huh). What would be the maximum ideal temp for throttling? Maybe I think about it too much, since under normal circumstances, I never exceed 70 degrees, besides benchmarks.
Also wondered at which temp is the phone supposed to shut down... 120 degrees?! XD Because 100 seems ridiculous to me, probably is, but yeah, my laptop throttle at 85, and it's a laptop (Intel Core i3) - Can't imagine a phone going any higher without any risk.
Thanks for the feedback

Looking for those of you who know what is a safe operating temperature for these qualcomm processors. With the kingklick kernel overclocked, the CPU can get hot quickly and I'd rather not fry my chip for a measley 10% speed increase.
So... I want to put some failsafes in. Right now I have it so my CPU will revert back to the stock 1ghz when it hits 40 degrees celcius, which is fairly easy to hit when watching streaming video (ie. Hulu) or heavy web browsing. I have a second failsafe at 42 degrees celcius which underclocks the CPU to about 500hz.
Is this too conservative? Looks about right? I honestly have no clue, I just wanted to put something out there for now until I can figure out an acceptable temperature range.
The processor, in a lab environment, may have a different operating range. And I think that's what you're asking for (manufacturer's spec). If I find the docs for that, I'll edit this post.
But in actual use (i.e., inside a phone, near other hardware components), you probably want to consider other things. And with that point in mind, the key statement relating to operating temperatures:
The Battery Pack has [an] ..
Operating temperature range: 32 °F to 104°F (0°C to 40°C)
Click to expand...
Click to collapse
This is from the user manual. [Edit: Rather, from the ProductSafety &Warranty Brochure.]
the processors can stand temperatures up to 170 F for an extended period of time
will your phone ever get that hot? no. the phone will freeze and cease to operate at around 140-145 F.
not to mention the battery itself will be pretty hot.
My gt-i9192 can get a bit hot. Reaching even 45 Celsius when I am outside using for example the maps app (needs gps, data and wifi (it claims it makes GPS more accurate and it seems to do)). or a game or browsing the web. Specially if the environment temperature is high (I consider 25º or so "high" for environment temperature). I am not sure if 45 is too much or if it is just okay fine. It does get uncomfortable and the temperature guard app defaults at 40º for the "too hot" warning.
How hot is too hot?

Keeping GPS on does get hot, particularly if you are using a navigation app. Depending on the games, some times it can be also demanding. But if you also get 45 degrees on browsing, than something is wrong.
You sure if the app is reporting the correct temperature? 45º should be warm to hold in hand (a feel-able temperature).

Sure, I feel the hotness.
I used to get 45 degrees while browsing if the environment temperature is hot. It hasn't happened in a while, recently I moved to a custom kernel, so maybe that fixed it.
My i9190 has been getting really hot lately, and whenever it does the battery drains crazy fast (about 35%/hr). Strange thing is, the task manager shows no apps consuming CPU nor RAM.
I had a similar problem with my old S2 that started after I had had it for about 9 months. At the start of a day battery consumption wasn't bad, but if I used it for an extended period of time it would heat up, and battery consumption seemed to rise linearly with the amount of heat the phone was emitting. There were incidents where it drained to half from full in a matter of less than an hour.
I welcome. I have i9192 and at me temperature at the game on facebook also achieved 45 "C and I returned it to the shop. At other users of this phone what temperature is while looking the Internet through??Can the shop he will accept the warranty??
Ah, I did forget one thing, since I didn't stay on original ROM for long. For those that are on original Samsung ROM, I guess it normal, since the default CPU governor is set on 'performance' mode. Your CPU is running on the highest speed all the time, and most original ROM does not enter deep sleep.
JoeCastellon: If you are on the original ROM, it would be your problem of battery drain. Using a custom Kernel or ROM like vexorian would solve your problem.
groda: Same, if you are on original ROM, running any app even if it not games, it would raise the temperature at a very rapid rate.
I thank for the reply. When install root and to lower the clocking of the processor? by the way, the new ROM will lower the temperature?
My latest "[doh this got too hot]" experience was on Sunday, I was using c0bain's kernel which AFAIK has the "on demand" governor.
I am now trying SilviuMik's ROM, will test during a week and see if the hotness happens again.

Custom/modified ROM or kernel will lower the temperature. Original Samsung ROM - no.

For me a battery is overheating. I want install root and new kernel. I have a question. Which kernel will lower the temperature for me? As install new kernel could update whether I will be through wi fi??
The kernel itself will not magically lower the temperature. You will need to manually undervolt the cores to achieve that, which requires a custom kernel which supports undervolting.
Changing your kernel will prevent OTA updates, if that's what you're referring to with the update through WiFi
My cores are working now on the maximum. install the root can I lower the clocking of the processor this way?
It which kernel will be good for my i9192? What thread is it possible to find him in?
Yes with kernel and appropriate app you can adjust clock settings.
Not sure if 9192 has a custom kernel that supports this. Check the development subforums
Okay found one.

Hey guys! I've been playing a PSP emulator on my note 3 and it runs pretty hot. I was wondering if anyone had any idea of how hot is too hot for the cpu. The battery stays pretty cool so I'm not worried about the battery temp, only the cpu. Thanks in advance!
The cpu's in these things will produce some heat when fully ramped up.

Anything over 100 f I would be concerned about. Enjoy!!!
Sent from my SM-N900T using xda app-developers app
The phones have a thermal throttle, so you should be fine unless you adjusted the throttle. In that case you should already know what's safe and not. And just an fyi, 100 degrees f is not hot for a cpu. Just when you feel something warm to the touch, that item is already at about 100 degrees f.
Thanks for your replies guys I really appreciate it!
I saw in a forum, 90 degrees for note 3 is still normal

Do you mean 90 C? Because I expect 90F ambient temperature whole summer and the phone has to be at least that much, even when shutdown. Add a little bit sun exposure and it can easily hit 120-130F without doing anything and I'm not talking Death Valley, Phoenix or Vegas, up there with outside temperatures hovering around 110 F or more, unless you don't come out from AC cooled room at all whole summer, the phone will be hot. If I remember correctly my computer CPU would start throttling somewhere around 80C, but my computer's GPU could go close to 100C. I would think phone is similar, except without active cooling, it probably starts to throttle sooner.
I use Battery Monitor Pro, and it keeps track of daily temps for the week. My lowest is 97.2F, and highest is 104.2F. It gets hottest playing games, but nothing so hot that I have to stop. As previously said the phone has a built in throttle. You can even know when it kicks in as the screen will dim a bit even if you don't have automatic brightness on.
EDIT - And by lowest of 97.2F I mean that is the highest for the day it recorded, not the lowest my phone runs at. Sitting idle with the screen off it's around 86F right now. I've seen it as low as 76F.
My droid incredible would hit 118F on a regular basis. My GN3 so far has stayed below 95F. Live in Phoenix, but it it's just now starting to warm up.

Is Touchwiz DVFS what controls the throttling?
Hello. I have noticed that my mi5s has some lag while playing asphalt 8 even at medium settings. After doing some benchmarks with 3DMark I realized that there is a drop in performance at relatively low temperature.
At "Ice storm unlimited" I have a score around 30,000 when the cpu is cool. However when I hit a 36 degrees of Celsius I am around 27,400. Furthermore, if the temperature increase at 39 Celsius , the performance drops even more and 23,500. This gets even worse when I hit 40+ Celsius where the score drops under 20,000 and if I semi-covered it with a cloth to reach higher temp it gets around 16,600 at 45 degrees of Celsius. After that it need to cool down to 33 degrees of Celcius to restore its performance
Needless to say that these temperatures are very easy to reach when you are playing a game. Has anyone noticed something similar? Any suggestions?
I have the 3/64 version with the 7.7.20 developers. Same issues were faced with the 7.7.6. . I have not tested in depth with the global rom but I think I had similar issues (it was only for a day). The room temperature is around 30 degrees of Celsius.

If you're okay with the high temperatures then you could disable all the CPU thermal throttles from any kernel manager app, though you need to be rooted.

I was thinking something similar but I do not want to disable it fully but just increasing the threshold by 2 or 3 degrees of Celcius. I am rooted but I am not sure how I can do the modification. From some quick search that I have done there should be a file named thermal-mplampla.conf (I do not remember the exact name) where you can modify it but I am not sure by how much should I change the respective lines for just a 2 or 3 degrees increase.
Anyone that have been playing around with thresholds and have any tips or guide before messing around?

First of all, that isn't the CPU temperature but the battery temperature. This phone actually has fantastic thermals due to its aluminum back and well placed SOC. No wonder you're getting throttling, you live in 30°C and you're playing games, what do you expect? Every phone on the face of the earth will throttle to that level. Just saying, your CPU is running probably around 70-80°C while playing intense games. So if you continue to play, it will eventually heat up the rest of the phone.
40°C destroys a batteries lifetime and 45°C everyday will reduce your battery within half a year which is why they throttle phones. Hell my One plus 3 in 30°C weather will throttle like crazy and that's the best phone in terms of throttling. Its normal. Stop playing crappy games like Asphalt 8 in 30°C and go enjoy the sunny weather instead.

Actually the truth is somewhere in the middle. I have used an app called "cpu temperature" but if I check the battery temperature it shows exactly the same degrees. So I guess it mistakenly shows the temperature of the battery. Do you have a more reliable app to check cpu temp?
On the other hand, 30 degrees of Celcius is not that high. In the winter usually we do not let the room temperature drop under 20 degrees since we use heating. Nevertheless, I will let it as it is for now and check again after 5 or 6 weeks where the temperature should be cooler.

You need a rooted phone to see actual CPU temperature. The best way to do this is get an app called simple system monitor (blue app icon) and go in temperature zones and you'll find a bunch of sensors there. There's a bunch of them that are for the CPU and you kinda have to figure it out yourself (I don't know exactly which one it is, one of the tz_sensor ones) by running a CPU benchmark and finding the ones that show the highest temperature. If you were to remove thermal throttling, and maxed out the CPU and GPU, you will see your CPU hit around 100-110°C and your phones gonna shut down for protection. And I'm in Canada so 30°C is extremely high haha.
Attached below is a picture of my Hardware activity while playing Power Rangers Legacy Wars which admittedly is a graphically intense games but I'm worried that the temperature of the GPU and or CPU is getting too high. I want to make sure my Note 4 isn't getting too hot here is the picture:
I need somebody's help. The coolest my Note 4 seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius
If you're worried about high temps during games I'd recommend turning the max GPU frequency down. It significantly reduced my temps and I didn't notice a significant difference in gameplay.
Thank you for your response. I have done that and it does not seem to make a difference I'm still getting CPU and GPU temperatures in the high 70s to low 80s

Would you mind posting a screenshot as above with the same overlay? How long are you playing before it gets to this point? Have you adjusted throttling temperatures?
Edit: Saw your other post and wanted to add some troubleshooting. When you open up TWRP and do a file transfer or backup how hot does your phone get? Mine would get pretty hot to the touch, but I don't remember it getting above 80 C.....
The temps you showed in the other thread are definitely not "normal" from my experience with day-to-day use. Did you ever look at the task monitor app I linked to?
Sure I can take another screenshot. How do you want it? I did check out that app and the only thing that I saw was that it seems as though my CPU cores were always running pretty high but I didn't see any applications taking up and unusual amount of processing power. The temperature ranges to about 60 as soon as I open a game for the most part and continues to slowly rise from there. Yes that's about the temperature I get everytime I go into TWRP. I don't even have to be doing anything I'm just open TWRP work and that's about the temperature I get

Sorry, I posted that before I noticed your updated screenshot. I was just curious if limiting the GPU made any difference.
Honestly I'm running out of software suggestions. Do you have some sort of case/screen protector that could be affecting it? How hot us your screen (qualitatively)? I just looked at an old video I made and my phone was 52 C in TWRP, which isn't too far off from yours so it might be fine (as I said my phone screen would get too hot to touch at times during intense games). But if you look at kernel adiutor and see that the CPU rarely drops to the lowest frequency/deep sleep there's probably something wrong (unless your screen is constantly on). You could try a different kernel or governor, or check an app like gsm battery monitor to see if GPS or something us hogging CPU time, but I don't really have any more ideas. (Although I did used to cool off my screen with a wet towel when it got really hot)
Just to confirm: you're running a Verizon note 4 right? (Have to ask)
You've updated the modem to the correct version through Odin?
You're on the proper bootloader?
First of all thank you for your help once again. I don't know how to measure how hot my screen gets I don't have any tools that would allow me to do that I do have a case and screen protector on but it doesn't seem to be any worse than it was before I put them on. Yes I am on the correct bootloader and I do have a Verizon Note 4 running the nseven ROM and I am on the correct modem. I'm willing to do anything at this point. This is the second note 4 I've had with this issue and I just want to be able to use it. I want to be able to play my games and stuff you know. So if there's a literally anything I can do . plus I don't really have money for a replacement

I found this: https://forums.androidcentral.com/s...bout-cpu-temperatures-according-cpu-z-s6.html
Which shows some pretty high temperatures during heavy and normal loads for a G4 and some other forum discussing how their note 4 would reboot due to overheating. Since you're not experiencing that issue I'm not sure you need to worry too much. Your processor should be throttling itself if it's getting to hot to make sure it doesn't get damaged. I'd try to make sure that you limit your gpu to around 300 and then just make sure your CPU isn't overclocked and you will probably be fine. My note 4 would get so hot that I couldn't touch the screen, but it still ran like a champ and never rebooted on me. The only thing that is concerning is that your CPU clock specs aren't sticking, but you'll need to read around for how to fix that since I've never had an issue.
Okay well that makes me feel a whole lot better thank you. According to GSMArena the processor speed of the Note 4 is 2.7 gigahertz and mine is currently running at 2.4 so while it is a little upsetting that I can't bring it down any further, at least I know again according to GSMArena that my processor is not overclocked. Thank you for everything
