I have noticed that after a few days of using, the back of the phone esp. the lower part tends to get warm/hot to the touch after using it for internet via Mobile Data. I haven't noticed this with games or watching videos. My phone is already rooted with CWM installed but I haven't played with the settings of the CPU.
Can you consider this normal? I came from Galaxy S II and the overheating issue was well documented while playing HD Games like those from Gameloft and other intensive activities on the phone., even if the unit is on ICS.
No. They must have sent you a miniature nuclear reactor instead!
Seriously, there are LOADS of threads on this.

I have the same problem, and the samsung rep i talked to about this told me to get a new battery, i will go get one tommorow,you should try the same.

I am experiencing the same behaviour, but only if I use the handset for extended periods. It isn't too hot to hold though by no means but I can understand the concerns about battery.
Looking at this though, http://www.ifixit.com/Teardown/Samsung-Galaxy-S-III-Teardown/9391/1#.T-AmIxeXSjP you can see that the Processor and all the other heat worthy chipsets are located in the lower portion of the handset.
Well that is completely normal in many cases. the lover part consist of the battery and most of the heating units. Mobile data consumes battery. try to play a big game like nova for 20 minutes and check if the heat is still there
I only experience this whenever I use data packet connection for internet. WiFi and other activities like playing HD Games and watching movies, the back portion is relatively cool if not just a little bit warm.
Here are the temps that Ive monitored:
1. WiFi: 29-32'C
2. HD Games: 29-31'C
3. Movies: 29-33'C
4. Data Packet Connection: 29-43'C. Please take note that if the Data Packet (Mobile Data) is on and I leave the phone unattended for almost an hour, the temp. reading slowly goes down to 30'C.
Would you consider these temperature readings normal?
I need expert advise from you guys.
Many thanks!

Hello.
I thinks it's normal...
But if you whant to compare, try that.
Download stability test app from google-play and run CPU/GPU test.
After 16 cpu passes it show me 42c.
Room temp is about 29c-30c
Also the phone is not in my hands τo avoid the temperature of my body and also without any case.
What's yours?
Thanks
I tried that app and tried that test. Mine passes and registered 41.5'C.
Is that ok?
But I think the primary culprit would be the modem, the one responsible for the 3G connection.
I dont think there are available modems flashable via CWM at the moment.

Hmm, maybe you're right.
Try to flash a diff modem from here and compare the result's.
As for flashing you can try MobileOdin. (I have the pro version)
I can't do that now cause i'm at work..
I change the modem as advise by ausdim. It improve my connectivity and I noticed that it went to a maximum of 41.3'C.
Just to be on the safe side, I placed it in room-temperature and put it o a flat surface, to be exact on my writing pad. After 30 minutes of browsing, most of the readings are from 38' and below.
Would you consider this to be a significant improvement?
Hrm, perhaps the US version will be a plus because of the lack of the overheating exynos. I'm ordering mine tomorrow from sprint
which modem did you use ?
Let it run the cpu+gpu test for 19 cpu passes and it was at 39.4°.

I am thinking not to buy yet an SGS3
my first galaxy s3 model got extremely hot towards the bottom of the phone and temps around 49 celecius...i exchanged it through expansys....then my replacement phones back casing had cracks, so i sent it back for another exchange from expansys but that one didn't get as nearly as hot as the first one...hope my third replacement will be ok...sigh...if not i might just go the att route...
My experience
The first two days I had my phone, I was playing with it non stop for about 4 hours and mine got really warm too [bottom 1/3 of phone]
I was playing NOVA 3 with all radios on, and possible a few apps running in the background. The battery lasted less than 3 hours.
I just figured that it would have to as these powerful high performance electronics devices do tend to heat up.
Now, two weeks in, I have not noticed it since, so for me I'd put it down to new phone syndrome.

I had 3 HOXes before my SIII and they all became uncomfortable hot. Specially the ring around the camera was litterally burning hot, couldn't touch it.
But that was not the reason for returning it, they had other hardware faults.

Just had a quick question about the operating temperature of my atrix.
My previous phone was a captivate, which NEVER felt hot to the touch unless I ran the GPS for awhile.
It was the same for my Atrix until I ran a graphics intensive game for about an hour or so. It started to get hot while playing, so I stopped for awhile. Ever since then, it is almost always warm to the touch and is continuously operating at 50C+.
So, is this normal? What are everyone's operating temperatures?
Miine runs warm under higher stress. It is a dual core processor so heat will be higher then other phones

ive never had a phone get this hot. this is how hot my pc gets lol. is this normal?
this result was after taking quite a few pictures with camera360 i noticed the bottom of the phone VERY hot.
these are about the temps that i get. it especially heats up when using data connection for web and not wifi. with wifi, it peaks at about 50c and on data connection it can go up to 57c.

Strange how people have dif experiences. My Captivate was always hot always! It only runs slightly cooler now with one of the latest CM7 nightly.
My Atrix gets warm sometimes but I never have the extreme heat other users report. I dont use and task killers, only watchdog to monitor for runaway apps. I do use a Commuter on both.
My phone only saw the 50's when I left it charging under a pillow.When to ATT store and got it replaced.Replacement phone runs all day at 35C never seen it go past that.
And do use a commuter case aswell.

Hmmm. My tempstature is 50°C at idle, while connected to WiFi. Is that bad?
EDIT: Well no, it goes back down to about 38° when you leave it for a while. But 50° temps are quite common.

Its my understanding that the Atrix IS running a dual core optimized version of Android 2.2. Afaik our current version of Blur is NOT dual core optimized, but Im not 100% on that. Is Blur what you are referring to.? Also, apps have to be written to take advantage of both cores, so if the app wasn't specifically programmed to run on dual core it will run on just one.

I've started a thread early today because of this issue. Soon as I started playing games on my Atrix I got pretty scared with the temperature I felt on the exterior, and more scared after using temp. monitor apps.
http://forum.xda-developers.com/showthread.php?t=1249757
The idea is to mod the phone to help dissipating heat. Besides undervolting with setcpu I guess there isnt much that can be done at software level to reduce the main chip's heat.
The ideas are still being formulated. I opened the thread so I could get some help and suggestion from other atrix owners, to have a good idea of what to do when I finally open my phone
could drill some tiny holes in the battery cover / just throwing that out there
unlocked bootloader att. atrix. honeycomb rom. faux oc kernal
Did a bunch of looking around and after a while found some white papers with the following temperature ranges:
General operating temps of -40C to +85C.
Practical usage will start to drop off below -20C and above +70C.
This tells me that our safe operating range should be limited to the practical usage temperatures. Anything outside of these and there is a good chance you will see performance drop off fast, and also may suffer hardware lockups, etc.
Personally I will stick to +65C which is the rule of thumb I go by with my PC's under full load.
<edit> <edit> I would also add that while our phones are not desktops/laptops/workstations, the CPU's can all handle around the same temperatures in all devices. Materials used and manufacturing techniques are almost identical. The solder used has a melting point of around 180C - 190C, so there is no fear of melting the solder. The main difference is that phones do not have active cooling, so you will see much larger jumps and swings in temperature. This being the reason you cannot OC in the extreme ways you can with PC's.
My rule of thumb is to keep my phone under 50c Max. The battey chewing alone is bad enough above 45c.
Ideally, I try to keep my phone below 40c whenever possible.
If it's a constant problem, then I usually try to find a different modem or fw. Which can make one heck of a difference...

Hello all,
Recently i bought Razr XT910 (1 month ago). Because of failure on power button on first handset, provider exchanged it with new handset, now everything is ok except..
On both handsets comes up overheating issue when i was using HSDPA/3G network data for internet surfing. In 20-30 minutes back side and front side (LCD) comes very hot. Application for battery temp shows in idle cca 27C after 30 minutes just web browsing comes up to and over 40C.
This never happen if i play games, watch videos. Also heating is not present if i access and browse over internet on WIFI connection. And i didnt root phone yet and i already done factory defaults.
Has anyone experienced the same problem? Any suggestions?
Specific of my phone:
651.73.30.XT910.NonEFIGSRetail.en.EU
Android Version: 2.3.5
SPU: 11 M1-2
Radio Version: U_03.1C.85P
Bootloader Version: 0A.67
Webtop version: WT-2.0.0-113
Thanks
Try to use the phone at different places. Check the signal reception. Low reception means higher transmitting power needed. So, more power needed and makes the battery and transmitter circuit work harder.

Thanks for reply. I tried this at work where i have full signal HSDPA (antena is 100 meters away and signal is very good), and at home i have very good signal on 3G network. I am not sure that the signal strenght is reason for heating... What about Radio Version: U_03.1C.91P, what improvements does it have?
I am on Asia GSM , HSDPA with 85P baseband. Everyday I download several podcasts from twit.tv and it is getting warm, but it cools back to normal after the download is finished.
Check any background process which may uses Internet connectivity all the time.

Normally you see high temps with heavy 4G LTE/CDMA phones. Haven't heard of many GSM phones on any brand ever overheating. May want to return it again. Sounds faulty to me, and the hotter you run, the worse your battery life will be.
@got556
I read about phones 4G LTE/CDMA with high temps, but as far as i know my phone is 3G (gsmarena). Mybe it is faulty, but this is second one with same issue.
@bahathir
can you mesure and post here battery temp while dowloanding or surfing internet for 30 minutes? Mine also cool down when surfing is finished, but meanwhile...it worries me.
I will check background services for activity.
Started at CPU temp : 31.5 degree Celsius. I am using OS Monitor app.
Opened YouTube and watched one of the clips in TheAlexJonesChannel. At the end of 7 minutes clip, CPU temperature was 35 degrees Celsius.
Next 15 minutes clip, temperature was 37 degree Celsius.
Another 15 minutes clip, the temperature was 38 degree Celsius.
Signal strength : -89 dBm. WCDMA only mode
Room temperature : 26 degree Celsius.
Now, it cools as nothing was happened.

I wouldn't call it was overheating since your case is normal. If you surf 30minutes nonstop over wcdma, any phone will get noticebly hotter but it wouldn't like you can't touch it.

What he said. An active mobile data connection will produce a lot of heat, especially when using 3G. When on 4G, your phone is using up a much smaller portion of the total available bandwidth so the radio doesn't have to work as hard, whereas over 3G your device and radio have to work much harder to maintain the necessary data rate.
This can be compounded by factors like ambient temperature, GPU accelerated applications (browser), the physical layout of the device's hardware, and even how you hold your phone while using it.
The good news is, 40°C is not a 'dangerous' temperature level for your battery. Given how high your ambient/idle temperatures are, you're really not generating that much more heat.
In general, I don't think you have to start worrying about Li-Ion batteries until they hit about 45-50°C (don't quote me on that), at which point you start running into issues like thermal runaway and damage to the battery.
Hope that helps.

Sorry, double post, but this is important:
Every Android device I've worked with will generate MUCH more heat when connected to AC power (there is a scientific term for this phenomenon, but the name escapes me). With rooted devices, I tend to account for this by creating an underclocked profile in SetCPU for when the device is plugged in.

Hi all.. My Razr XT910 touches 45° when I play games like angry birds or similar ones..is it considered normal?
Sent from my XT910 using XDA
Hi guys,
I am sorry for (very) late reply Recently i hit 44°C with active web browsing (facebook,news pages...) and i didnt watch any movies in about 20 minutes. The phone was really hot and it was very uncomfortable to hold it and touch it. In the meantime i contacted motorola support. After their advise i set phone to factory defaults and then i also exchange micro sim card (for free) just in caseif there is any problem with it. But problem is still present. So i decided to take phone to repair centre. They tested the phone for a few days and they said the phone is working normally. They also reflashed my current SW....On friday i got phone back and problem is still here...Now I wonder how they tested the phone and what is for them to normal operation. And i am also stuck at SW version. Does anyone know what are differences betwen GB,FR,DE, NonEFIGS and other versions? Is there just language difference or is also hardware diferences?
I am also worried what will happen in summer with high temperatures outside..
Well, I don't think is something unusual... Its same like your laptop - if the system is busy and the processor has lot of work, it gets simply hot..
Keep in mind that the razr has two cores and if you are playing games or watching movies or even browsing web containing some flash etc. it may get hot because the cores are running at 1,2ghz and it generates heat...
I don't think its something surprising and you will face it with every nowadays smartphone..
If the temperature don't get down after few minutes the phone is idle, check if there is some stuck process because it seems that most likely there is something running on background...
I personally use the System Tuner which gives me a great overview about the current phone's load etc...
@maarawoe
i undarstand what you are trying to say. But web browsing over WIFI does not generate that much heat, the phone gets a little warm not hot as on mobile data (aprox. 35-36°C) and also when playing angry birds or something dos not get that hot.
As i said i am just concerned what will happen on summer time.I hope that the phone will not explode
I will try that app to see more details what is happening with system.

WiFi hotspots are usually 100m away at most; but since the range from cell towers can be measured in kilometres/miles, the power needed to talk to them is much higher. Some of this power is lost as heat. All devices with HSPA and LTE radios get somewhat hotter when the data connection is used heavily.
Recently trouble shot this same problem for someone else. Try this:
1) Turn off Wi-Fi
2) Go into wireless settings and DELETE the saved profile for the Wi-Fi network you're using (make sure you know the network key first)
3) Turn on Wi-Fi, reconnect to the network.
High temperatures are common under certain conditions, such as being connected to AC power, using multiple radios simultaneously (ex: GPS + 4G), CPU/GPU intensive applications, and of course high ambient temperature.
45°C is not dangerously high, but can indicate other problems. Anything higher than 50°C and you may start experience issues like thermal runaway (battery rapidly discharges).

Hi, thanks for replies.
@JPtheSmith - high temperatures are present only browsing net over 3G (we dont have 4G..yet). Even if Wifi is turned off. If i use Wifi for web i dont get so high temperatures. And the ambient where i use my phone is around 20-25°C. Maybe there is some incompatibility between phone gsm module and provider network. I will try to get another provider sim and check it.
I had a long talk with Verizon tech support about high temperatures.
The main causes.
1. Bad signal area, makes the phone work harder.
2. Running to many apps. To many Background apps can and will over-tax your phone.
3. Last but not least, HD games will max out your phones resources.
So, i will make this blunt... This non overclocked phone gets hotter than any other mobile device i have tried...
I am already on my second one, after number one hit 125 while sitting on my desk. This one has hit 114, which is still unacceptable really, since the room is climate controlled to around 74...what happens when I use it in the summer??
Now, by virtue of need (infrastructure tether) , I am using the ICS beta, but I cannot believe it will effect it that much. I have a 3.7v battery, so that should be good.. I will admit that I am in a building that does not do well for 4g, but frankly, my phone burning itself up just searching for a signal is unacceptable as well...
I am about ready to throw in the towel and try a GNex, even though its radio problems scare me too...Any advice guys?
what apps are running, also is this while it is charging?
Just want to start with a big thanks for all of your work over on the nook boards. The overheating has been an issue since the start. I am on my third because of it. I only reach high temps when playing games. I can stream movies all day long, and never get over 110. I am waiting for an aftermarket battery that can handle the drain from this beast phone. I guess it depends on what you will use your phone for. Glad to see you here, and hope you stay. Sorry I couldn't be more help. Good luck....

Most apps won't affect temperature in any real way.
Tethering requires broadcasting wifi signal, and equivalently large wifi broadcast (broadcast SSID, and all data) at an equal speed to the ultra-fast 4g.
Now, this 4g phone (as well as ANY OTHER LTE PHONE RIGHT NOW) will overheat if you download a 300-500MB file at a fast 4g speed (like 25 MBit for instance).
Overheat. Untouchable.
Wifi tether (even on 3g) will overheat a phone if you're using a decent amount of data (rather than using it for short bursts).
My HTC Eris, I had to leave the back battery cover off, and put a cold can of soda (with a paper towl in between to stop moisture) to keep it from overheating.
The Rezound will get so hot that you literally can't touch it.
Charging WHILE you tether will make it a lot worse, as the chemical activity within the battery (to charge it) is going to increase heat. Add that to 4g cell phone connection, and the wifi antenna getting hot broadcasting, and you've got a 125 degree phone (which IS hot enough to start breaking solder points).
If you have it OFF the charger at that temperature, you will notice that the notification light is now flashing orange/green back and forth. This means that the unit is overheating and should be shut off, immediately.
Get the extended battery to hang out and wireless tether for a while. It generates a whole lot less heat if not on the charger, and seems to (maybe due to the case that has more space for air in it) not heat up quite as much, in my experience.
Tethering can overheat your phone. 4g can overheat your phone. Add charging to that, and it doesn't matter how many rezounds (or GNEXes) you get. These things have no real ventilation, and there's no indication that they're going to start designing them with good ventilation that I know of.
Good luck, power user. Users like you force them to think about their poor designs and improve them. But it definitely won't handle a lot of 4g tethering without overheating. I'd expect that, without ever even having a Rezound (even though I have one).
They say 130 is the kiss of death for the Rezound but even if you're peaking in that neighborhood I'd swap out the phone for a new one. 120-130 degrees...That's like keeping lava in your phone and hoping it doesn't melt.
I hit 130 with my Inc1, and it was fine. Just navigating, not charging, for 30 min did it lol.
Mine heats up excessively and burns thru battery even sitting idle with airplane mode enabled and GPS turned off (damn Verizon and their location agent they snuck in with the update). The issue here is:
A) I'm not using it nor touching it period for a few hours at a time and its still already below 30% battery without my having used it.
B) yes I have an extra battery but when I try to switch out batteries it goes into a bootloop and won't recognize the Sim card for the next half hour.
These are my problems. I have yet to exchange it cause let's be honest...who here enjoys setting up a whole other phone? Should I seek a replacement?

Back it up to your ext card and exchange. Don't forget to hard reset. They are sending refurbished units with prev owner data out there. Should only get hot when playing intense games or streaming lots data.
I had this heating and severe battery loss problem. There were times my phone would run fine and other times when it would lose 40% battery in 30 minutes. It seemed to be worse when I was moving around the city (changing towers???). I even had one experience where I turned the phone off and it continued to generate lots of heat until the battery died while supposedly powered off.
I tried every stock and rooted GB rom (no ICS) on XDA and a few not on XDA. I finally "fixed" it by RUU'ing my phone to the latest OTA, rerooting and reinstalling all my apps (no TiB). My phone now runs about 16 hours on a charge and only gets slightly warm (never hot) when you would expect it to.
I did a fair amount of reading and never did find an answer but my suspicion is that something between the rom and radio got out of sync resulting in the rom not controlling the radio properly. No science. Just a theory...
Hope this helps someone, somewhere. I know I've gotten lots of help from others on here.
Thanks!
Had many heat concerns/ issues with my rezounds in the past, now have a phone that games at about 115. My opinion after much research is that a 115 peak is about normal for this generation of phones (Gnex, S2, etc). Anything better than this is not the norm and if you get one that stays cooler, it's just luck. I had one that used to get around 150 so at 115, I never even notice anymore. My rule of thumb is to just keep exchanging the hot ones until you get one in the comfort zone. Unfortunately, it's just the reality we're dealing with until they start equipping better cooling solutions.
OK, first I think we need to understand if people are talking F or C when they throw out numbers like 124. If that is C, you have a seriously defective unit. If that is F, that is like moderately hot tapwater, and neither too hot to touch nor hot enough to damage solder joints. If it were, the computer I'm typing this on would be dissolving in my lap.
Welp
I have many a thread out there on this topic. I did 3 swaps for new units during my extended "no regrets" window, and this past week got 2 different refurbs for comparison. Here is my 2 cents (but based on a LOT of research and testing):
1) These phones run hot. If you look hard enough at XDA you will see people posting along the lines of "I don't know what you are talking about, I use my Rezound to chill a beer" and other such. You might be best to ignore those people.
2) There are some VERY bad Rezounds out there, but those are easily found. Those that jump to 130 straight off because they started to download some updates gotta go back. That was refurb 1.
3) My experience is that idling at 75-80 will produce 106 on a short HD game, 110-120 on a longer HD game. You might get 113 on Navigation. It will heat up to 100 on surfing (longer if you have more), but otherwise topping out at 120. If you fit within this, stop your search, and try to enjoy your phone.
Again, just my 2 cents.
I haven't done extensive testing, but I have noticed that when my phone has overheated it has always been when I left something running on it when I locked the screen. I've started hitting the home button every time I put down the phone for more than a few minutes and I haven't had many problems. I definitely get toasty when I play games while charging though.
As someone else already mentioned, the phone needs to get quite a bit hotter than most people are experiencing before it starts having problems. With how small the phones I would expect you would receive an instant 1st degree burn from touching it before the phone actually had problems. 150 C is somewhere around 302 F. For reference, I usually solder 400 F.
My first rezound got around 135 degrees I took it back the next day.

This laptop is running at 120F just looking at this website, and it has active cooling.
Imagine a 1.5GHz dual core PC and then unplug all the fans, including the one on the CPU, and then close up all the openings in the case. Do you think it might get a little warm?
Not only do you have the CPU generating heat, but the more current you draw from a battery, the hotter it gets. And we all know how this phone can draw the battery.

Mine heats up excessively and burns thru battery even sitting idle with airplane mode enabled and GPS turned off (damn Verizon and their location agent they snuck in with the update). The issue here is:
A) I'm not using it nor touching it period for a few hours at a time and its still already below 30% battery without my having used it.
B) yes I have an extra battery but when I try to switch out batteries it goes into a bootloop and won't recognize the Sim card for the next half hour.
These are my problems. I have yet to exchange it cause let's be honest...who here enjoys setting up a whole other phone? Should I seek a replacement?

There is something wrong with your phone. I swap batteries instead of charging, swapping out 1 extended battery for another (got them onsale at verizon when they were 20 bucks), and the phone boots up in about a minute.
If it is bootlooping, then I would try a hard reset first, then contact verizon and tell them about it.
As far as the OP goes, if you are in a poor signal area, I have read in multiple places that phones use more battery and generate more heat if you are in a poor signal area.
Swapping this for a Nexus will probably get you no 4g at all.
I wouldn't worry about the phone unless it was consistently getting so hot that the LED starts flashing amber.
My Rezound has peaked at 140 according to System Tuner Pro. I was charging and web browsing as soon as I woke up, like what I'm doing now lol. Was on 3G. Also, I wasn't overclocked at all. Governor wasn't even on performance lol.

lol dude, there is no point in ignoring us people who say our rezounds run cold, because of the fact that there's rezounds out there that don't exhibit behavior like yours.
i've seen all of your threads, and commented in all of them, and you got 3 shotty phones, plain and simple man. my phone never reaches over 100, even with over an hour straight of screen on browsing, facebooking, youtubing, gaming etc. so there, i have a normal rezound. it's from launch day, and it's never given me any problems like that whatsoever.
so no, don't ignore us who have cool running phones, because there IS such a thing..some people just have really bad luck dealing with it.
also keep in mind that the past two phones you got WERE refurbs. you do realize the refurb pool is gonna be full of hot running rezounds, since a lot of people returned the phone due to heat problems, right?
I believe some of the Rezounds get hot due to software issues. My phone will stay room temp and run for 16+ hours on a standard battery while running any GB rom . Once I flash any ICS rom my battery averages 90 to 120 degrees. As it is charging next to me right now, it is sitting at 104 degrees while doing nothing. I could switch back to a GB rom right now and it would be sitting around 80 degrees. So I believe some if not most are software/firmware issues. I am not saying their aren't ones with hardware issues but it can't be all of them.
I have ran the OTA update and am running Senseless ICS.
Hello!
I have some concerns about the heat of my phone. I've read some threads, but everybody has different opinions and readings.
Basically, with room temperature at around 27-28, during browsing (especially with lots of scrolling through images) the phone will heat up to 40-41C (even to 42 with some encouraging) within 5 minutes, so the bottom front and back are very hot.
During other use, like writing a few messages in Whatsapp, going though settings in programs, menus etc it will, slowly, but will go up to ~36-37C.
Is it normal, or should I prepare for war with the shop I bought it from?
are you rinning a custom rom/kernel or stock? if so which?
I've found that different roms heat up more than others.
I'm using anaraxia rom 10.3 build and have no heat problems and the battery life is amazing!

Using a stock rom. I'm not experienced enough to flash custom roms yet, and I would also prefer to not void the warranty, at least since I'm not yet certain that my phone is not damaged in some way
I'm not that bothered by the heat, my only concern is whether this behavior is normal or not, and whether I should start the whole warranty war sooner.
Well I wouldn't be bothered tbh.. I've had 42°c while heavy usage and charging. If your phone overheats and burns out send it in then.. No point doing it now unless your warranty is out soon?

41.5, but how much did you strain the device? Today in a room where the temp was +-30-31C, while browsing XDA (which seemed to strain the device a bit) I got up to 44...
Also checked the idle tempretures, it's usually the same as the room temp at the moment, so it's not that it's always hot, just when used.
R: [Q] Regarding heat
Its weird that it should heat up while doing normal stuff...im on international version and last time it heated up was while i was playing modern combat 4 online after 2 hourse while connected to charger....so maybe youve got prpblems if it heats up like that only by viewing messages. I watch videos and browse the internet everyday, it never heats up. Im using stock rom and syiah ketnel...

While doing regular stuff like messages etc it doesn't heat up much. The first test was done while browsing, but I kept it at 40% load and 1400mhz, so it can't not heat up. I think that room temperature matters, I live in a hot area, today was 31C.
s it normal, or should I prepare for war with the shop I bought it from?

I don't know where you live but in most civlized countries you can go in all guns blazing and they have to prove you wrong within the first year or so =) They will, of course, try to tell you sth different...
but will go up to ~36-37C.

I've had that "problem" (well it's not really a problem, only a minor annoyance during warm seasons) with stock rom too.
Didn't have that much experience with other roms and kernels (I'm very picky with features) but I never noticed it on Siyah with Wanamlite.
Stock kernel is far too happy to ramp up clock speeds to slightly improve response time (or so is the theory... practice is not noticeable) so it will heat up your device. More heat of course also means higher battery drain .
Note that a protection around your device usually keeps you from noticing this fact (while the phone gets even warmer due to worse cooling)

I've also noticed this heat problem, I'm also on a stock rom.
Using the "CPU power saving" in the Power Saving setting has helped, so I figured it was the kernel ramping itself up.
It's not that noticeable to run at a lower cpu frequency except that some games are sometimes choppy now
The fact that stock rom likes to ramp up the clock speeds is correct. Just by simply fast scrolling back and forth through pages on forums etc makes it go up to 1400mhz and keep it at 40% load, that's why I get the higher temps.
hi guys i want your help because my dad has samsung galaxy s2 and he usses 3g 17 hours a day mazimum and he charges hes phone 2 or 3times a day, is it normal???
and for example: when i play modern combat 4 5 minutes the phones temp go to 40C and when i play 20 or 30 min i cant touch the phone can u help me guys?
is there any romor kernel i should install for him?
the phone is running 4.1.2 stock jellybean arabian
please reply fast
thankyou
It's normal for a phone, or indeed any electronic device, to heat up when you give them demanding tasks. In your case, you play Modern Combat 4, so you should expect it to heat up even after a few minutes of gameplay. Same applies for battery drain, you should expect the battery to drain if you play games. 17 hours is average for minimal usage, I get 12-16, and I class my usage to be slightly below average, including 10-30 minutes of NFS: Most Wanted, Trapped Out, or GTA.
Do you use a cover on the phone? And does the phone have overheating issues when you use it normally (browsing social networking apps, newsreaders, internet etc)?
Overheating
I even get overheating when I'm on Facebook App or surfing the web on Chrome!
Especially the part near the rear camera is the hottest!

What worked for me, on International SGS2 with Jelly Bean 4.2.2 Android OS (Jelly Bam 7.6.0 custom MOD).
I followed the instructions in the first post of the following thread to flash KH3 modem instead of the one I had: http://forum.xda-developers.com/showthread.php?t=1656005 (you can do it even without root access.
Then I downloaded NS Tools from Play Store and set CPU maximum frequency to 800mhz.
Now, I get 36 degrees Celsius as a maximum when playing Aporkalypse: Pigs of Doom. Before, it was over 45 degrees. So it got better. Still heats up (cause it's 30-33 in standby), but way better.
I hope this helped!
Same problem for me.. it realy fear me i played asphalt 8 15minutes the phone heat up like hell..will this cause any hardware problem like display..? Two lines are appeared in the top of my display will this due to heat..?

That's perfectly normal as mentioned. If you run CPU/GPU intensive tasks like a game with graphics like that, the phone will get hot. It's a small package that has those hot components fully enclosed with no real way to dissipate the heat (unlike a PC which has fans & heatsinks, for example).
You could do kernel-side stuff like underclock a bit, but you might find your game unplayable if you do that.
So if you want to play games like that on a phone, you live with the heat.
If the lines only appear on the screen when the phone gets hot & go away when it cools down, then it's obviously caused by the heat (which is probably causing the GPU to do funky things).
What heat will do is if you expose those components (CPU & GPU particularly) to those levels of heat regularly, you reduce their life/increase the risk they'll fail at some point. Given most people get new phones every two years or so these days, this isn't normally a problem unless you're spending hours a day exposing those components to that kind of heat. But the other thing involved here is, not all components are created equal in the factory/have the same tolerances to that sort of thing. Manufacturers do their best with QC in this regard, but the same components in different devices (same model though) can vary a little quality-wise. And you have no way of finding this out or testing for it.
So yeah, you can either keep playing games & live with the heat as I said above (and with what I said after in mind), or you can stop & have a cooler phone.
All samsung phones has this deffect..? Can you suggest me a phone(sony,samsung) without this overheat issue with same performance...?

It's not a defect, it's basic physics/electronics design. You make a CPU or GPU do a lot of work (do more/faster calculations, which is what they do in essence), they get hot. Same holds true whether you're talking about a PC or a console, they just have ways of venting that heat.
I have no experience of what other manufacturers phones do, but it's the same with the S4 & I'd be very surprised if other manufacturers phones aren't similar - because they're all enclosed packages with components that get hot crammed into small areas with no way to get rid of the heat. Their design is basically the same, ergo, they'll all behave in a similar way if you do similar things with them.
If you want to play games without heat, get a console or a PC.
