I can't see your phone so I don't know what is exactly going on, but if you type into Google any smartphone name and word "overheating" you will see dozens of threads and articles. People are just overreacting, smartphones are getting warm it's just their nature, plenty of processing power etc. If yours is getting too hot maybe it's some app working in background.

My phone gets very hot on top of screen, near speaker

My phone is also overheating very quickly now. It started after i rooted the phone and installed some root apps like greenify and clean master. I have now disabled those apps to see if it helps.
Anyhow, it's not a big deal. It won't burn up so what is all the fuss about?

I have the same thing, the same spot as you mention. On samsung stock rom its really worse!, but on cm its decent. however, my pone always turns off when testing antutu at stock max cpu speed...
I can only go to 1674mhz. any higher and it will instant shutdown on antutu

hi, i'm from singapore
and im using the i9505 variant of the S4 and i'm having the same issue about the heat on the top half of the phone
it heats up so bad i cant touch the top half of the phone at all
Is this caused by the 4.2.2 update like what everyone says?

My view/experience with i9505 on (over)heating. I direct this at Samsung ...
Dear Samsung,
Please can you move the WiFi Power Save Mode Toggle from the Service Menu and place it in the standard Settings Menus. Also make this setting persistent between boots.
On certain AP hardware and/or configurations, the Power Save Mode does no saving at all, in fact in my experience it just causes a huge mess. The culprit is spotty/erratic WiFi connectivity which causes all the background sync/update tasks to go in retry loop heaven (with wakelocks galore). These background tasks in retry loops hammer the processor continuously such that it start heating up (& draining more battery than normal).
So please implement this small change so that it can save many a lot of headaches.
Thanks.

Heating is a big deal for me. S4 is a lot more hotter then my former S3, and not because of the CPU. For me it's because of the modem. Root might be related also (I had my doubts on this) ... some apps keeping the 3G up more then needed, but I don't want to speculate more ...
PS: there are others "overheating" posts , a lot of them.

Same issue here (thread here), my brother has the same model and we tryed use same apps on both S4's, his S4 does not heat but mine does. so something wrong with my S4

i think the rom is causing all the overheating issue.
when i used stock, it would heat up that i can't touch it
now using phoenix rom 2.0 for 9500, and only get a slight warmth

My first smart phone was an Galaxy S2, and it got hot, i had two replacements they were the same, i then realized smart phones with powerful cpu/gpu`s just get hot when they work hard, i had had a few smartphones since the S2 from a few different manufactures and they all get hot, now i have an htc one, and it gets hot so it`s totally normal.
what i have realized with android is that you can get a faulty app or system process that really kills the cpu/gpu for no reason and they need to be shutdown/killed.
So i started using an app called watchdog, just change the settings to monitor system processes as well.

my friend is using i9505 as well and his doesnt heat up like mine does
when i bring it over to Samsung, they said 'its normal'
and they said nothing can be done about it

My phone was overheating as well, and I found out the culprit was media server. It got confused with some old thumbnails I had on my old SD card (from my galaxy S3), I had thousands of pictures there, so I guess it was constantly scanning it.
So delete all the thumbnails, (there's a folder .thumbnails in DCIM I believe) or even better yet, if you can, format your external SD card, and copy the files you need on it again. then mediaserver will work hard one more time and that's it.
Alternatively, you can download Rescan Media ROOT, and disable the media scanner, and enable it when you need it (but that's not desirable for me, I'm always updating my media, so I prefer it being automatic, depends on you usage)

The S4 does heat up quite often, what version you using? I would recommend to use KT kernel to underclock and undervolt so it doesn't heat up as much

Ow i like the heating part on my SG4 its really helpfull if ill ever go to Antarctic
Its a life companion.

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

does your S4 get hot below the camera?

Hey guys,
i noticed my phone was getting a little hot while i had the navagtion app going.
im using the S4 flip cover and right under the back camera, where it says Samsung - I felt the phone getting hot.
Anyone experience this?

Me too

It's always hot.
I mean it gets hot often.

Of course it gets hot because the CPU is right there.

According to the manual you shouldn't be using the phone at all when charging

Loool really? Its always under charge when i play or the battery drops in 2 hours i disconnect sometime when it become too hot
Sent from my GT-I9505 using xda app-developers app

Using while charging is fine unless it is overheating.
The reason it's recommended not to use the phone while charging is because it reaches high temperatures much faster and so is more likely to overheat causing hardware problems
I personally don't game while charging since this phone (especially i9505) gets really hot really fast

yes i know that heating its very rapid while under charge..expecially now that its so hot during day and cant dissipate...in may when i bought s4 had less problem
i think i must think to buy an extended battery to play more than 2 hours hehehe are they already on stores?

Almost every good phone gets hot now and then. My rooted S4 barely gets hot. I mean i flashed a great rom (omega rom) and flashed an amazing kernel (perseus) and played a bit with cpu voltages and i undervolted my cpu and it barely gets hot , and when it does , it does not get very hot .

i tryed to underclock processors but,maybe i just made a mistake, i saw the battery drop much faster...i setted max speed at 1.2 last time but never tried again

OMG, OMG, OMG, finally!!!!:victory:
I thought I was going crazy, but YES, the phone gets unusualy hot just below the camera.
I noticed this right after performing the Apps2SD update, and since then have been freaking out!
I am afraid that constant heating and cooling of this kind can damage the sensitive parts inside,
so I have been limiting my use of the phone in the last few days.
People, this is not normal. Somebody needs to contact Samsung.
There must be a software patch for this...?!

Oh yesss!! Let's make another thread about overheating -___- It's already known that this happens, so you better get used to it.
Me Gusta!

Calling all I9500 Users with heat + battery issue

Hello Friends,
I wish to gather as much info as we can about the I9500 that are heating......because I was informed by someone at samsung that the devices manufactured after june have a revised PCB....which eliminates the overheating and battery problem.......I got my I9500 on 14th aug but in Antutu it was reching 85 degrees hence I will be getting a replacement tomorow....
Please use *#2222# to find out the HW Version : The defected ones (I assume not confirmed yet) are REV 0.6 because my friend has the same rev and his phone heats up as well........So if we succeed in getting more and more details we can go to samsung svc and ask them to atleast replace the motherboard....Cheers......
Heres What we need
Date Purchased :
Date Manufactured on the box :
HW Ver :
How hot does it get :
Does the heating affect battery life :

I dunno about 9500, but i am using 9505 and it was hot when i got it.
Ever since i switch to this kernel with proper undervolt, it doesn't run hot anymore.
http://forum.xda-developers.com/showthread.php?t=2284252
Maybe ask the guy if he have a port for 9500
Use wheatley governor (huge improvement to reduce heat since it doesn't bump all the way to max cpu all the time).
My battery life nearly doubled, can last 15-20 hours easy depending on usage.

theres an app called temp monitor if you go to the preferences of that app you will find an option that allows the processor temp to be displayed it statusbar all the time....now this app is not available on the play store and i cannot share it as i dont know if its a paid app but you can google for this app....cheers!!!!!!

Hi. mine is REV 0.6 and i bought it on June 12th. when i first got it it heated for no reason after 5 minutes of light use, but i never checked the degree. but after an ota update. the issue is gone and at most extreme conditions it reaches 70-73 degrees.

That's great let's see what happens after I get the replacement

honestly, if your problem is only the heat, i am pretty sure a better cpu governor would solve your issue. lets face it, these phone will get hot, running close to 2ghz, quad cores with NO active cooling... even my desktop cpu gets around 45c with liquid cooling man...
i am sure the temperature is an issue using all existing governor (except if you use powersaver or conservative, but is slow), but the wheatley does a good job keeping the phone smooth despite staying at the lower end of the cpu speed as much as possible..
i got my S4, eventhough we have triangle away, i never planned to return it anyway, i'd just deal with the heat problem, in fact, at the beginning before i even discover the new kernel, i just manually reduce the max cpu speed to 1.6Ghz, and that solved the heat problem.

Thanks a lot for taking the time to explain things.....now the issue i have is i can manage normal heat or for that matter heat which is above avg as well...the only scary part is my phone reaches 85 degrees most of the time.....it doesnt behave like an octa core.....its just like a a15 quad core and the heat is very very high......

As I have a I9500 if I root the device my warranty will be gone as samsung people will reject the same because i rooted it.....also on the stock rom I am getting less than 3 hes of screen on time......hence requested for replacement....as I do not have the option of rooting the device till triangle away is available for I9500.....

Rev 0.6 here. Spectacular battery life 5-6 hours screen time. Overheat issue is "almost" gone for me. Atleast the heat is not enough to bother me while browsing and general use. Heavy gaming makes the phone quite hot though, out of the comfort zone of placing the top of the phone in your hand.
Purchased my S4 in June. Had horrible overheat issues, hickups,restarts, battery level suddenly jumping to low followed by a restart.
Every single one of this issue got solved by the firmware update. Latest MG5 (Indian). So please update to this one if you haven't already (Flash it) and report your temp, general battery life etc with us.

Yup Been MG5 since Day 1 and have done multiple factory resets still the temperature issue exists even the svc confirmed that the heating I have is a hardware issue,,,,,
*********If anyone from india recently bought the S4 they have a offer going on wherein 1 screen replacement will be done for free by samsung till the device is under warranty you can call samsung cust care and give them your purchase date they will confirm if the device is eligible for a free screen replacement!!!!! So for me no more screen guards needed,.....

I am running MG5 (Indian) firmware stock, no root, hw rev 0.6. I did some measurements today with cool tools
Ambient temp : 29°C
Idle processor temp: 37°C
Light task processor temp: 43-50°C
Web browsing heavy pages: 45-60°C
Playing sonic 4 ep1 : 59-67°C
Antutu processor temp: 70-92°C
Antutu score: 27.896
Pretty standard temp behaviour I guess. The overheating in my phone seems to be the inevitable one that comes with such a powerful (and unfinished) processor.
If someone gets a new hw rev we could compare at a given conditions (ambient temperature, apps running etc..). It might not be very representative, but it could be fun.
So say we all!! from my GT-I9500

Rev0.6
Bought last June 14..
No "overheat issue."
Heavy gaming makes phone hot but not to the point of overheating. Also after flashing a new rom it gets hot on first reboot (just wait for the rom to settle)
Every smartphone gets hot in a certain situation and thats pretty normal..

Best battery stats of my s4
Got 2x 7 houra screen time
But usually my usage is between 5.5 hours to 6.5hours screen time
I think you really got a bad device and not a batch defect. Good thing they will replace it for a new one.
I suggest update your device yo latest firmware or root and install custom rom and kernel.
Eventhough we have less available rom and kernel for now, the good thing is that they are all very nice and devs are great.

Too much heating

Hello everyone,
I recently bought my new redmi note 7 ( 3gb ). It is working fine but it is heating too much and very often. Normally at my place temperature is about 38 - 40°C. When i am using my phone i feel it warm even when i am just surfing internet but when i play games it burns like hell. Also thermal throttling is lot more than other devices.
So it would be great if anyone would help me in this.
Note:- I have debloated most of the apps and also my bootloader is unlocked.
Thanks.

mine only heats up when gaming, i'd recommend flashing evira 1.9 kernel and using LKT magisk module and setting it to turbo mode thats what im using right now, little to no thermal throttle at all.

If you notice overheating by now i totally recommend you to use the product's warranty
