[EXPERIMENT] S4 Overheating and how it affects battery drainage [PLEASE PARTICIPATE]

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
---------- Post added at 10:02 AM ---------- Previous post was at 10:01 AM ----------
oh and i have half the brightness all the time for everything and auto brightness turned off

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...

Yes we can read cpu temp and battery temp separately, use system tuner app to read cpu temperature.

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.

Is your S4 over-heating too quickly?

Hi,
I got my S4 around 2 weeks ago, everything works fine, but it just heated up abit too quickly & sometimes you couldn't even touch the phone, so i asked Samsung about this problem, they replaced my phone but it kept and happening. So i decided to do some research, i didn't really find anything on the internet, im not a hardcore developer but i know my way around things
After doing some testing to see why it heats up & where, i figured out it was the RAM & CPU. I have around 300 apps installed, that's included system apps too, so 300-130= 170 user apps. So i flashed the latest ROM i could find because i thought it might have been a bug or something, it got abit better but still got really hot .So i decided to root & delete all the bloatware & apps i didn't need, after i did this i found a script on the forums to do this automatically, its not hard to find. It wouldn't heat up as quickly but would still get really hot. So then i decided to go to the extreme & disable all the fancy features the S4 has like Smart View, Air View etc. You know what, my phone hardly heats up really hot!
I also put it into power saving mode, it hardly has no affect on perfomance but my battery can last a day but still be on 40%.
So yes, if your S4 is over heating you have to disable all the features you bought the phone for, c'mon Samsung

OT; that's some awesome Math skills you got there, lol.

No over-heating here.

Only playing Ingress...

anyone here specially any Exynos version user plays dead trigger alot like 40-45 minutes continuously? How's the heating?

So far my 9500 isn't overheating. My nexus 4 would hit 55-60'C on the cpu. My S4 didn't go over 50 yet.
Sent from my GT-I9500 using xda premium

I think it only effects around 15% of S4 owners, it effects both I9505 & I9500
& lol, changed it to 170 haha

i used I9500 Octa version and no overheating at all :good:

Here's what NotebookCheck DE found. If your i9505 is performing differently I'd guess something's amiss.
Temperature
All this raw power squeezed inside the Galaxy S4 has to produce a lot of waste heat. Luckily, Samsung's engineers have managed to keep the Galaxy S4 cooler than the Galaxy S III. Despite all performance improvements, we never measured more than 42.5 degrees Celsius (108.5 degrees Fahrenheit), a value only achieved after hours of stress tests under full load. This maximum temperature, which occurs next to the ear speaker on the front, is actually 4 degrees less than what we measured for the Galaxy S III. It is only while idle that the increased excess heat becomes noticeable: In this case, the entire surface of the Samsung Galaxy S4 is a few degrees warmer than that of its predecessor.
Heat generation is still very much acceptable, even though the HTC One feels cooler to the touch thanks to its metal case. The hottest device was the Nokia Lumia 920 with up to more than 50 degrees (122 degrees Fahrenheit) under full load, much more than what the Galaxy S4 reaches. Fortunately, the small power adapter remains rather cool as well while charging the phone.​http://www.notebookcheck.net/Review-Samsung-Galaxy-S4-GT-I9505-Smartphone.92829.0.html

[Q] Note 4 heating, hardware or software?

Hello everyone, I recently purchased a new note 4 St N910C. Just after a day of usage I felt that it is getting hot when I play games on it. I closed all the background apps even resetted it but still no luck. My phone is getting heated up near the camera area. My question is that is this a hardware issue or a software one, because if it is a hardware issue I should try and get it replaced, if a software one I should better wait for a lollipop update.
Any suggestions would be gratefully appreciated
Thanks

It is completely normal that your phone gets hot around the camera since you are playing a game...What is the temperature you get while playing?

Would also like to know how hot your unit gets
when playing games. This is the unit that i am planning to get

Well i bought this unit after along study of whether to get the exynos version or the snapdragon version, in my opinion I found the exynos to be better because many users suggested that this version does not heat up and works better, but now as I'm using it personally I think it heats up alot, the temperature I get is around 36-38 degrees.

Galaxy Note 4 heating [camera]
I purchased Galaxy Note 4 [SM-N910G] a week back. It's on Android 4.4.4 (KitKat)
I am having a different problem for which I could not find any satisfying solution on the Internet. Whenever I open camera app, the phone starts heating up near camera & battery also drains very quickly [around 2% under 5 min.]
I know that the phone will heat up a little bit when playing high graphics games, but I don't think it should heat up too much when using camera app.
I have already factory reset [both soft & hard reset] the phone, but still it does not help. I contacted Samsung support, & they told me to 'Reset app preferences' from Application manger, but still the device heats up when using camera app.
I also cleared data of the camera app, but still the issue remains
The phone does not heat up at all on standby mode, but opening camera app raises it's temperature more than it should. Previously a Note 2 user, this problem was not there.
Anyone else experiencing the same issue on Note 4 ? Any ideas on this ?

The phone heats up only if you're recording 4k or 2k video.If you use camera generally & your device heats up.You must get your device checked

You can factory reset all day, it won't help. Thats not a problem, the camera just uses a lot of processor power and thus generates heat. You can't change that, you have to live with it

My note 4 with ****y snapdragon heat like fire
I wanna replace it because of the overheating I can't something even hold it I put is always in freezer to cold it
With cpu temp app it gave me 60c even without games the :crying:best value was 40c but when I put it in freezer it down to 30c
And the weard thing that at the same time the cpu temperature app gave me 60c the cpu cooler app gave me 34c
Weard which is right? ??
This phone is making me crazy

Sorry, but do you have any idea about CPU temperatures? 60 isn't bad. 40 isn't bad. 30 isn't bad. Even 70° and occasionally 79° would be acceptable. Don't put your phone into the freezer, ity not good to freeze the hardware.. Especially if you literally have no problem. The CPU is prone to temperature fluctuations and your values are fully normal in the world of CPUs. There is no best value, everything up to 70° is the normal temperature variation. Your phone doesn't have a problem, its perfectly fine.

Mine actually heats up while charging and using at same time. Clean master shows 70-75°C cpu temperature while using browser and stuff but 80+ while gaming, that's not normal right? I'm worried cuz I always used my old phones while charging and they never got this hot, I feel like it will melt someday :/ In what temperatures exynos operates?

I got my SM-N910F yesterday and installed LP 5.0.1 via OTA. Temperatures are 40+ when the phone isnt doing anything. While I did the Antutu Benchmark, it was around 50-52 degrees (Celsius). Feels much warmer than my previous Note 3 (which of course never had LP). And since i am not used to this temparature on my Note 3, i kinda worry about the temps right now. I read a lot that many have that problem since LP update. So whats normal and what would be too high for regular usage (not using Camera or playing Games) ? Is there an average i can go by and compare ?
And whats my alternatives now if I want lower temps , go back to 4.4.4 Stock Rom (currently have LP 5.0.1 Stock) or do I try a 5.x Custom ROM . Did the Custom ROMS fixed these heating problems or is that just something I have to live with ?
Thanks for any help.

Look 2 replied higher, already wrote something aboht that

My old G3 used to sit at 50 degrees idle!, 30 and 40 degrees is cool!!!!!!

Sure that makes all the difference ? I read a lot of posts from people saying that a factory reset didnt really solve their problems. Do you know for sure it will help ?

❄ The LG G4 TEMPERATURE THREAD ❄

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.

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.

I've noticed that phone is getting hot when charging even if the phone is in standby. I'm getting around 40-44c.

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.

Thank you all
Please add which sensor are you referring to and with wich app you use to read sensors

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
it even shows that hot temp message / stops charging
try broadcasting for 5 mins

Intersting comparison between M9, S6, G4, Droid Turbo heat dissipation HERE

Periscope heats up the phone like crazy!

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.
Wish I would have done it 3 days ago. Might have been snagged another battery and leather case lol.

Note 4 snapdragon Getting Hot

Hi guys,
I have purchased Note 4 recently and it seems to be heating in minimal tasks also like surfing the internet. i have flashed KITKAT, LOLLIPOP(default) and MARSHMALLOW but in all these firmwares the problem seemed to be consistent. Earlier i used snapdragon phone which was clocked at 2.3 GHZ and used to heat @ heavy games like No Limits, with recording on but this one is heating in angry birds itself. Though no lags are observed. I have not tried the Marshmallow version latest yet but some body told that latest update fixed heating issue. The root problem i see is its Processor clocked @ 2.7 GHZ, i mean this much we see in PC. I dont understand why they have gone so far. Now Samsung kernel must be clocked such way that on demand it bumps the frequency to max. This max i want to limit to 2 GHZ but without knocking down KNOX warranty. If some one has latest updated Marshmallow release and can confirm that it is indeed not heating please comment or tell me the solution to this problem, i really like this phone but hate when it heats. I am ok with slight lagging due to underclocking. i am willing to flash kernels with lower max frequency via ODIN. No custom recovery intended. Also i dont want to loose on warranty.
Thanks and Regards,
Really looking forward to solution

I have a Verizon Note 4. I did have heat issues with Lollipop. Since I installed Marshmallow and did a factory reset, it only gets warm with heavy use. Some app updates have had my Note 4 running warm, but a reset of the phone seems to fix it.

Seems like custom rom is the only option bro

The Snapdragon 805 SOC does have a bad habit of getting really hot when running heavy tasks.

Not only was my phone Hot for every second I used it but... Look at this amazing SOT.
I finally figured out how to keep Google play services from draining the battery: burn through your entire battery before it even has time to start up.
