Am using a combination of Paranoidandroid and Franco kernel, and as widely discussed, the device gets hot at times very hot. So apologies if this has been discussed before, as I did a quick search but nothing came up, so what would be the gradual effect of the phone overheating, as clearly this must represent to some extent irregularities in the phone system DDoes it slowly cook up the internals of the phone, or maybe perhaps the phone is designed to withstand such heat, so just concerned because I use my phone at least 15hrs a day, so just concerned.?
I'm not a hardware pro so take this with a grain of salt. I think that long-term heating of the internals will have minimal harmful effects on your hardware. It'd take years and years for it to actually affect your device, long after you've upgraded. The CPU has undergone plenty of testing to make sure it lasts for a long time under self-inflicted environmental factors such as heat.
would also like to know. but not sure about what is considered hot/really hot.
the max CPU temperatures i reached were around 56°C (133°F), but thermal throttling on francos kernel is set to 70°C (158°C) by default (i lowered it to 65°C/149°C just to be safe).
if i remember correctly, i read somewhere that li-ion batteries dont really like being above 42°C (107°F), so when it reaches that temp, i immediately let it cool off.
so to sum up, thermal throttling is there to protect the soc and the hardware around it, so i would be concerned about the parts on the motherboard. i cant recall where i read that temp limit on the battery, so i cant state anything for sure about that.

It won't affect phone's hardware afaik, the cpu itself has thermal guard and will automatically shutdown itself if the temp reach 110 or 120° (not sure between those two).
The one that may affected is battery, it may reduce your battery lifespan or even explode it if it's too hot, but it's hardly happens.

How hot can this phone get without being damaged? When I use GPS/MUSIC and have it charging...it gets to 114.5 F!!!
While it charges from a very low 10% battery life...it gets to around 105.
Very good question in my opinion.
I too saw those kind of temperatures before I took measures to lower the heat.
Between SetCPU/Undervolted Kernel I have gotten things a decent bit lower(26c-34c) Idle - heave use
This includes a profile that limits phone to 576 when charging. I also have not tried adding GPS which clearly does increase temps. This should raise it some, but should still stay lower then "stock" where i reguraly saw 35-37 with totally normal use.
I may give GPS a whirl on the way home just to test it.
Let me know how it goes with GPS. Been holding off on the undervolt kernel. May have to give it a try.
AFAIK Lithium-ion operating range is -30—60C (-22—140F), so nothing to worry about.
Cool...so does that mean...the phone hardware (besides the battery) is gonna be okay also?
I was just wondering if this issue was unique to my device. Whenever I browse on 3G, any task from minute to high-energy consumption, I notice that the area right under the battery bay builds up heat without fail. It doesn't happen when I perform any other fiction on the device, just with 3G. The heat dissipates in a fairly reasonable amount of time, about twice the rate at which it builds.
For example, the list of forums on the XDA-Developers page takes about 2-3 minutes to load in its entierity, and by the time its done i can easily distinguish the top of the device from the bottom, simply because of the heat building in the lower part.
I'm trying to figure out why its happening and if its possibly a defect? I haven't made any modifications to my device thus far, with the exception of a few bumps and bruises as a result of my clumsiness, so should I exchange my unit? Or is it anything to worry about?
Heating up happens with all smartphones these days because of 1ghz processer so its normal however if it gets too hot the battery life could be shortened and the CPU life if they are close to each other. So I suggest that if it goes more than 40 C then you should turn it off. Also to get a rough idea of how hot 40 C is try it with water and see how hot it is.

Hi this happens on my phone as well. I have contacted Dell and they will be sending out a replacement to me.
Dear Community,
In this thread I want to gather a sample to investigate to what extent the S4 suffers form overheating and how this affects the battery drainage/life. I urge you to participate as I am collecting a sample to submit a formal complaint to Samsung to raise awareness to an issue that is widespread among S4 users and to push Samsung to address this issue accordingly. In order to provide your sample please follow the instructions below and report back in this thread with the relevant information. Please first indicate which variant you have: Quad/Octa (i9505 or i9500)
Please download BatteryGraph (it's a great app to measure Battery drainage accurately) https://play.google.com/store/apps/details?id=com.modroid.battery
Run it once after download to initiate logging. Let it run for 10 minutes to allow the graph to built up a bit.
Then please Download Antutu benchmark run the benchmark fully exactly 5 times back to back (continuously). After that please enter the stock dialer (as quickly as possible) and enter *#0228# and post the temperature (external thermistor) after the tests in order to determine the maximum temp that the device reaches under continuous stress.
After that, please enter the app Battery Graph and zoom into the graph to the maximum level. Scroll slowly along the curve at the time when you performed the Benchmarks and tell me if there are interruptions or 'skips' where the battery drops 1 or 2 percent at a time and where the App does not Register a graph for those drops. Sequence/scroll slowly along the graph 1% at a time and make sure that the battery dropped 1% at a time. Please report of the battery has dropped more than 1% at a time. Please make a screenshot of your battery graph in the App and post it here for collection. I will analyze the graphs subsequently and compile it in SPSS to submit our findings.
If there is a drop of 2 or 3% at a time it means that you are experiencing Battery Percentage skips/cliffs which could indicate either a defective battery or defective device which might be the cause for the extensive heat development.
Thank you for your participation. Hopefully Samsung will listen to us and address the issue to give us the perfect S4 that we deserve.
Best,
Thomas from Germany

That battery app polls for battery level changes every 5 minutes by default. I think almost every device will experience a drop of more than 1% every 5 minutes under constant stress testing. You can change it to poll every 1 minute in the settings, which you might want to mention, but even so isn't it entirely possible to lose more than 1% a minute with everything turned on (GPS, Gestures, etc.) and ~17 minutes of constant cpu/gpu stress testing? It's a nice idea but it doesn't sound like it would yield very accurate results, unless I've misunderstood your post.
EDIT: Nevermind, I see how you can step through it 1% at a time now.

I've also noticed that you cannot really zoom in very far and at the highest zoom setting the % is still displayed in multiples of 10. Kind of tricky to differentiate between a 1% and a 2% drop.

You might be right, what would you suggest in order to yield more accurate results? I suspect that the heat is directly linked to a very quick drainage of the battery. How can we measure how much it affects the actual battery drainage?

I'm not criticizing you or anything and I'm not saying it's a bad idea, It's just that obtaining accurate battery results are tricky as everyone's device is different, has different settings enabled and are running different kernels/ROMs/etc. Batteries also seem to get more efficient as time goes on so newer devices might suffer from higher battery drains.
I'll run the battery temp test now though and see how hot mine gets!
I like your critical thinking, obviously you are right it is very trick but I believe the heat test itself could be very indicative. In the meantime I will try to find a better way to measure battery drainage.
So everyone please try to run the benchmark multiple times and submit the temperature.
The most I was able to get was 52C
Thanks
Pre-test: 29.9°C
After 3 tests: 35.0°C
After 5 tests: 37.7°C
After 7 tests: 38.4°C
After 10 tests: 38.8°C
The temperature increased less and less so I don't know how much higher I could get it.
Also, an easier way to poll the temperature is to do "adb shell dumpsys battery" over ADB. The temp will be displayed as something like 388 which means 38.8°C
Edit: It might be worth noting that the top of the phone, around the camera but more so on the screen side (so the cpu?) got incredibly hot. Almost too hot to touch. Kinda worrying, but I have spent the last half an hour stress testing, I guess

Thanks for your contribution Meltus! Really appreciated my friend. Also thanks for the ADB command it does make it easier but I doubt that you've read the correct temp as 38 appears to be quite low compared to what i got. Is your S4 a i9505 ?

It's also the temperature that dialling *#0228# gave me (I double checked they were both the same each time). And no, I have an i9500, running Omega ROM, if that helps.
Might want to mention the elementary precaution of taking off all case covers except for the stock case before testing to prevent insulation effect of case covers increasing battery temperature...
While you're at it you might want to standardize room temperature to 25 degrees C... I know for a fact that my device would never get hot no matter what it does if running in the freezing cold air-con'd metro...
What about brightness settings and whatnot. Should all be the same, so you have to give a standard.
Pre-test: 36.2°C
After 3 tests: 51.4°C
After 5 tests: 54.6°C
After 7 tests: 56.9°C
dafaq right??? im really annoyed at sammy for this overheating S4... after 7 times testing the Antutu, i stopped and LITERALLY put my S4 in the lower compartment of the refrigerator to get it cooled down quickly cause im pretty sure the heat sensors inside would definitely be having some testing errors and the temperatures would be really really higher than that. even when i swipe between different homescreens the phone gets to 47°C which is really annoying.
can someone pls for the LOVE OF GOD provide any solution to this freaking problem? i have been worrying a lot for spending my $730 on an overheating phone...
i have S4 i9500 Exynos version

Are you talking about the battery temperature? If so something is extremely wrong with your unit, my battery temperature never went past 45 even with high stress.
If in case you are pointing out the cpu temperature then there is no reason to freak out because the cpu can handle upto 90c + and can cool off pretty fast
Edit:
And why on earth you ran Antutu for 7 times continously lol? None of the current generation phones can handle it for 7 times on a row afaik

im talking about the cpu temps. i ran antutu cause it was asked to be done for this thread.
and why would it be silly to run any app 7 times on the flagship device? its made to run the apps as much as people want thats why we pay a huge amount of money for these devices dont we? or else we should buy the low end devices
just saying cause i had heating up issues with devices before infact my last device Note 2 used to get a lot hot but not as much as this S4...
i desperately need a solution for this...

You are not buying a flagship device just to run Antutu n number of times, do you? yes I accept we do pay huge money but that doesn't mean we can push the limit of a mobile and complain about it from a general user perspective . , it can be only done for experimental purposes and to understand the power /thermal envelope provided that it's done in the right way.
But how does running Antutu 7 times matches a real life scenario? Highly unlikely isn't it?
We are already pushing the limits of raw cpu power for a mobile, raw a15 cores are power hungry and often tend to heat faster than previous generation. Hence arm introduced the big little. The mobile heats up during heavy stress, but but that's expected with these powerful cores right? I'd better utilize the power wisely when needed rather than using it all the time. The cpu indeed gets hotter when stressed, it's the same With my s3 too the cpu temps reached upto 80,there is built in throttling mechanisms which will take of the cpu once the cut off temperature is reached. Have seen many benchmarkers these days using freezer test due to the thermal throttling in new gen devices. Yes the s4 heats up pretty quick than other mobiles but also cools down pretty fast and I think that's the way it is destined to work.
Hei one more thing, did you note how long it took to fallback to normal temps?

We were doing it to see if there was a correlation between excessive battery drain and overheating batteries. Mine never got any hotter than 40 and I have pretty great battery life. The OP was seeing temps of 50+ and I'm guessing he has poor battery life.
Could there have been a few batches of bad batteries sent out with devices?

Battery temperature. If someone's experiencing temperatures in excess of 50C and bad battery drain it would indicate a problem.
We all know why LG choose 808 over 810, now let's see the results of their choice:
Here we'll talk about the G4 operating temperature.
Try to indicate your ambient temperature, model, display brightness, app(s) used, your cpu utilization (I use cool Tool for it), and of course temperature (for that purpose I use Cpu Temp wich basically reads bms sensor of Cpu-z in overlay, and Cpu-z itself) ;
Remember to distinguish battery temperature from cpu sensors temperature and if using cpuz remember that temperatures are very sensitive to time so measure it only while performing the task wanted.
Keep it as scientific as possible
*I forgot to mention that CpuZ has an erroneous C to F conversion. So keep it in °C to be accurate
There is an intersting heat comparison HERE on Android Central to begin with
Good idea. Do note that CPU-Z seems to have a bug where it converts temperatures incorrectly from C into F, in the Thermal tab. From what I've seen, CPU-Z should be set to display in C, not F, if you want accurate readings.
To see the issue, check the temps, including in the Battery tab, then in the Thermal tab. For me, in C, the Thermal tab numbers seem reasonable, and the "battery" line in Thermal is close to the temp shown in the Battery tab. But change the units to F, and the Thermal tab suddenly reads the battery, and everything else, too-high by about 30F. The temperatures are not converting properly from C to F, the displayed C and F values are not equivalent. This conversion issue appears using CPU-Z on my last phone, as well.
So if posting CPU-Z temps from the Thermal tab, I'd suggest setting it to C, not F.
Thanks, I forgot to mention it, added
What's the point of this thread? This isn't a PC, it's not like we can do anything about the temps.

That is where you are wrong. It's called we can hard mod the phone for better temps.
Total newbie question, is the temperature you're feeling on the hand the one from the CPU, or the one from the battery, which is closer to the hand?

It should be the battery because I notice my phone getting warm pretty often and I have a widget for battery temperature which tends to go up to around 38 °C often. I didn't check CPU temperatures but I don't think the CPU is heating up too much.
82 F - sitting on the desk doing nothing but looking pretty. VZW, brightness at 0% and Auto.
All these freaking temperature problems will be resolved in a few months when the freezing winter arrive xdddddddddddddf

Lol, no, you can't.
At least LG choosing 808 instead of 810 due to hear issue was the right choice.
https://youtu.be/HltGLYZLySs
Take a look at a link above, SD810 might have upper hands during cooled state but that changes quickly throttling down below SD808 specs. SD810 potentials are pretty much obsolete and probably will never run on full more than 5 minutes.
SD808 is holding its speed even running hot. So I wouldn't really worry about hear part for this phone. But I'm with some users here. Few software updates will iron out some heating problems.

That's low for charging honestly if your referring to cpu temp. Most phone cpu temps stay around 25-35 idling and mid 40s when just doing simple scrolling and small tasks. 60-70c is fairly normal on heavier tasks and games. Kernels usually don't even start throttling until the cpu gets in the70-80c (generally most start shutting down cores at 80).
That being said, my G4 is one of the coolest running phones that I've messed around with. CPU-Z usually says that I'm in the low 40s even on some heavier tasks. I know that my Note 4 gets much warmer, much faster. Heavy web browsing for example will have my N4 in the upper 50s low 60s. The G4 stays pretty stable in the upper 40s low 50s. I'm happy they chose the processor that they did honestly. Stays pretty cool compared to the competition.
you can even mine cryptocurrency on this beast for hours on a normal (here normal) 27-30°C ambient temperature, and the battery gets to 44°C and the CPU gets into the 50s.
This phone has one of the BEST thermal management I've ever seen. I was a nexus 4 user, so you can see how much i was struggling.

I don't pretend to be rude, but that information is outdated and inaccurate. I don't know how the other manufacturers are doing with the 810 to be honest, the Z3+ is sort of new and I've been checking the threads but there's too early to judge so far, it happens that I do have an HTC One M9 up to date, stock and unrooted and I've noticed several improvements through updates. Considering my daily usage I didn't feel this was matching with what I experience in real life, so I decided to redo the test on the video. I ran AnTuTu benchmark 64 bits version 4 times in a row, and left an average of a minute (sometimes less, once was a bit more cause I took the wrong screenshot) between tests. The attachments were uploaded in chronological order, you can also guide for the hour displayed from the device.
Now besides the video only runs 4 times, I did notice it was holding every couple of tests and then decreases, so I decided to run one more for the sake of pure testing and check throttling behavior, and surprisingly the fifth run gave me an increase on the score instead of lowering it further.
I didn't find a dedicated benchmark thread on the G4 forum, unless LG had improved a lot the 808, and based on the several benchmark results you'll find across the internet, including the ones in that video, looks like even throttling snapdragon 810 holds as an 808 in worst case scenario.
About heating problems, if I'm providing a success case scenario with a more troublesome chip like the 810 is, I'm completely sure the 808 will be fixed in time
phone gets crazy hot when running Periscope

I too have had issues with the device getting very hot on the top half of the screen. Tried a couple of factory resets but it didn't help. Even reset one more time and kept it stock after a few hours same problem. Took it to the AT&T store and of course it was behaving fine. Luckily the rep knew me and accepted I knew what I was talking about. Swapping mine for one first thing this morning when their new shipment comes in. Will update if issue persists or not.

So, I purchased a replacement battery for my V20 from Amazon. I wen't with the Perfine 3,200mAh as I couldn't trust that the "original OEM" batteries were genuinely original. However, I've noticed (as one other review on amazon mentioned) that the temperature sensor in the battery isn't working. It constantly seems to read around 22°C no matter what. The other day my V20 became very hot during use, possibly dangerously hot (I don't think this was related to the battery, it was a fairly hot day). I checked the temps using Aida64. One of the temperature sensors, "tsens_tz_sensor11" read 71.4°C!! I immediately shut the handset down to be on the safe side. I don't think I've ever had a phone get this hot. Is that normal? Or even safe? And how dangerous is a battery without a temp sensor? - I'm guessing not very safe at all

So, I purchased a replacement battery for my V20 from Amazon. I wen't with the Perfine 3,200mAh as I couldn't trust that the "original OEM" batteries were genuinely original.

I've read the opposite that most of the knock off after market batteries are crap and you're best off sticking with a genuine oem battery.

Sorry, I didn't really make that clear enough. There are a ton of fake "Genuine LG OEM" branded batteries out there. They're all skinned like the official battery that came with the V20, with a few minor differences. This make it really hard to know whether you're actually buying a genuine LG product or not.
The battery I bought isn't a knock off, it's a third party battery. The capacity of this replacement is great, actually slightly better than the genuine one that came with my V20. The only issue is the dud temperature sensor.

71C is high, is that after running a benchmark or something?My note 4 used to go over 73c sometimes .My cpu idles around 28-30c ( i changed the thermal paste) and goes to around 60c under max load.I'd recommend changing the thermal paste for sure. Regarding the battery, it's probably the temp sensor on the Battery IC that's not compatible with V20?

I was on 4G at the time, and only checking Reddit and reading the news. Nothing intensive at all, which is why I freaked out a little. Room temp was probably around 30°C at the time.
I reckon you're right about the temperature sensor. It does seem to get some sort of reading but always hovers around the 22/23°C mark. Should I be worried about that? The battery obviously has a temp sensor for a reason. I really don't want a note 7-esq experience any time soon...

yeah you never know.When charging batteries( especially non-oem) best to have fully functioning one especially from a safety standard.Yes, there are good reasons for battery temperature sensor.It says a lot about the health of the battery , like if its prone to failure in the near future.This is a wild scenario but say if your battery starts expanding rapidly it's gonna be very hot and phone will be made aware(99% chance this isn't gonna happen but just an example).You may have noticed if you use Fast charge, the battery gets hot, nothing crazy but hot nonetheless.So if your device is fast charging, it may send false battery temp readings and fast charge may keep sending higher voltage or current(i think fast charge is like 9v) because as far as it knows battery is not at temp threshold. Obviously voltage threshold comes in to play primarily, but you get the the idea.That's just another scenario i could think of as an example.Have you tried checking temps with other apps like cpu-z for consistency? Yeah i see why your temp is so high 30C room temp, that's so hot lol Mine is probably 14C .
My battery definitely goes above 23c so yeah something is wrong there.
Interestingly i once made my phone reach 90c with lineage os running kernel auditor and cpu on max speed. I could not touch the fingerprint se sor. Im not sure if it was really 90 or kernel auditor was wrong. Battery and everything was stock.

Thanks a lot for the feedback, I reluctantly returned it today. It's a shame because it really was a huge improvement over the stock V20 battery. I've taken a punt on another third-party replacement. Fingers crossed!

Holy moly! That's ridiculous! haha. I know CPUs can withstand very high temps, but 90°C in a smartphone is pretty nuts!
