Hello XDA,
I decided to open this topic as I've been fumbling around with my device alot lately. Lately I've started to notice a dramatic increase of temperature while using my device running simple tasks like chrome, whatsapp etc. This only sometimes gets the device till 45-50 degrees Celsius, this is the CPU's temperature. While gaming, it reaches a whopping 60C ! Flashed to stock, updated to new base, reboot after reboot did not solve this issue. While charging sometimes it gets really really hot!
Now I'm wondering about your experiences, how hot does your CPU get doing what tasks? I'm wondering because im contemplating whether or not bring my device in to a service center as I've never had a device CPU above 45 degrees celsius.

I've always wondered if more users experienced the same issue, now i'm doubting whether or not even to send it to samsung or not. Any more people are more than welcome to share their experiences
Anyone else?

I think its normal.
Does your phone start to lag when it gets hot? If not, then in my opinion you are still safe.
Same here, but I only realized it was heating last month. Maybe it has something to do with a background process? Sometimes I can even feel the heat when my phone is in my pocket
It doesnt lag, but it does heat up ALOT while doing light tasks, up to 50C

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.
I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.
Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies
It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%
My screen brightnes is 0%. It is hot at the top where is CPU I gues.

How many degrees celsius is taken as very hot on the Galaxy S II?.
I was overclocking my Galaxy S II earlier and my temprature was up to 46 degrees celsius when i was running a stress test on the phone.
So i just stopped my stress test of the phone then.
How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.
the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.
You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

my phone was getting extremely hot when benchmarking etc, this was default clock and voltages.
the phone reported it was reaching 50 degrees. thought this was "normal". this was on the firmware the phone was running outta the box.
flashed latest firmware and have since messed about with overclocking, @ 1650 my phone never got as hot as it did stock.
so if you have not done it, flash the latest FW...
So your cpu is not 1200 but 1650mHz now?

Been running tons of different ROMs on tons of different Android devices, and every once in a while there is a particular combo that gets tremendously hot.
Once had my N1 get so hot while using Co-Pilot Live and Spotify while plugged into a car charger, that it turned off and wouldn't come on again for some 5-10 minutes.. Definitely worrying.. Switched ROMs and never saw the problem again.

When I use it intensively, for a couple hours it sure heats up, but not after 10 minutes

How do you even state heat up without mentioning the temp?
Have a basic idea, based on an ambient of 30°C,
Charging- 50-55°C,
Charging+ Gaming- 55-60/62°C,
Normal Use for more than an hour with WiFi On- 40-45°C,
Moderate Use for half an hour- 35-40°C,
Standby for half an hour- Below 35°C.
That's just an overall idea I tried to input.

This. Give us some temps of normal and when gaming to see if it is abnormal (there are apps on the market that allow you to do this). Chances are, it isn't. The phone has to use more power to run games and processor intensive applications. It getting warmer is normal.
when i fap i mean use my hand in a productive manner, it heats up (inside joke from irc chat last night)
Hey
Now. i know this has been asked alot before etc.. but i havent found my answer so im making my own thread and providing some information on my device
I got my Sgs4 a few days ago and ive been hitting temps of up to 60-62 ...
My questions.
a) These high temperatures, erh... arent they killing(not draining.killing) the battery? cuz i recently read Li-ion shouldent get above 40?
b) Is there ANY fix for this without root?
c) Should i rma it when its hitting such high temps? or will i just get a device where the same thing happends..?.
d) Would this possibly be fixable with a future software update?
Now, here's some information
Before the s4 i had s3 and i remember it being hot and shutting off in the first months i had it, but a update solved it. Buuut unlucky as i am i broke it :/ so i bought the s4.
My s4 is the quadcore Snapdragon 600.
I've done/gotten 0 software updates.
I've tried dissabling some programs (look attachments)
I've used power saving mode. still gets hot.
I've tried rebooting
I've tried changing the Micro sdhc and tried removing it completely too.
The only thing i found helpful was laying the phone on top of my pc fan :/..
Ive attached some pictures with my specs etc..
The temp was recorded using '' #*0228# '' code
Hopefully some awesome person will help me

Check in the battery stats if an app is consuming allot of battery and disable it.
Check using some cpu monitoring app like watchdog if some process is running high cpu cycles
Check if in flight mode the phone heats up. If not maybe wifi or radio transmitter is working hard.
Check if your reception is good or not in battery stats when clicking on the graph. Should be green if good yellow if bad.

How do i check the temp? Do i need an app?
So far based on my observations my phone heats up when playing games. As for surfing it heats up more if you use LTE/4g. when the connection icon changes to H it doesnt heat up as much when in 4g.
My workaround so far is when my screen is off, it auto shuts down all connections by using a profile manager app. No push notifications though but it does save up my battery and avoid heating. Im still waiting for an update that fixes this overheating issue. sucks to not be able to use push just for the sake of the phone not heating up...
*EDIT: nvm i figured the code out from the OP. mine reached 55c

type *#0228# on the keyboard. at the top it shows network state, then battery state and temperature, at the bottom it says "external thermistor" and that's the phone temperature. my s4 heats up to 50° just by browsing xda app, 65° when watching youtube. sometimes can't even touch the space under the camera it's so hot.

Ya mine heats up with just normal stuff. I don't play games on mine.
It cools down after a bit of non use, but it makes me wonder being as my Note 2 didn't get warm if I should exchange mine also.
mine only gets hot when i am charging it from the wall charger. the charger plugged into the wall is hot when i touch it also. doesnt get hot when charging from pc.
Overheating and throttling was big issue on Korean tech community/blog S4 reviews (exynos variant). Sammy responded immediately and released new firmware like a week later. It solved everything, way lower temperature and even faster. I think something with Touchwiz or driver related thing got messed up and casuing problem.

Yes the phone does get hot sometimes especially after 10-15 mins of continuously browsing the web on 3G+ or 3G and after 15-20 mins on wifi.. But that's for stock 4.2.2 and 4.3. After undervolting and underclocking the device using custom kernels and ROMs the phone does not get very hot.. It's between 37-40 even after playing games like nova 3 and nfs mw for an hour if you hold the phone with your bare hands and it obviously depends on your configuration.

Thin glassy phone + powerfull cpu = heat Nothing to worry about.
It gets hot, at least on stock firmware, although my definition of hot might be more sensitive than others. I don't know what it would be like talking on the phone for an hour with it getting hot next to your face, although I haven't done that. I have to use custom rom and underclock the cpu a bit, so it's not an really issue anymore. I probably will get flamed for this, but I don't recommend this device to you if you don't like phones getting hot. But I guess lots of these newer flagship phones that has thin plastic casing probably gets hot too.
With normal usage the phone doesn't get too hot or anything. If you are fond of overclocking and disabling thermal throttle you will get pretty high temperature's. Around 70 degrees celcius.
It get's hot as any other phone but because it has got a glass back you feel the heat better.

It didn't feel warm at all after undervolting and limiting heat using Trickster Mod (and has been yundervolted for the past 3 months).
Before that it could sometimes get really hot though.

Is your phone undervolted and temprature limited?
My temprature never goes over 40 degrees celsius, and feels rather cold most of the time.
Even with rather intensive games like NFS Most Wanted
This phone will not burn you. There isn't a real reason to consider the heat a problem. The temperature of the phone is regulated by the kernel, if it gets too hot the kernel takes measures to reduce the amount of heat being produced. This is a non issue.
