My DX2 frequently reads over 100F. How hot is too hot?
Sent from my DROID X2 using XDA App
Most cpu's can go to 120 safely anything above that and I would be worried. I don't know if the cpu on a phone is the same though. I would say you are fine.
If you're talking about CPU, you should be fine. My CPU usually reads 104-110.
If your battery is that hot you're in trouble though.

I tested the Inc, Droid X, Droid X2, TB, Charge and Revolution. All had similar temps in range of 1 to 2 degrees.
At rest just playing Mp3s = 84
Same but while charging = 89
Downloading with 3G = 94
Playing Flash = 104 to 115
The key reason the DX2 seems hotter than other devices is the metal cover. It helps to dissipate heat, but at the expense of your hand. The other devices run just as warm, but are insulated due to the plastic housing. This is good for the hands, but less efficient heat dissipation.
The DX2 still does have some heat issues though, since it can spike high and stay there, unless you reboot the device. Seems that Flash can trigger this behavior- especially 10.3. Seems best to stay with 10.1 that shipped with the device (IMO).
Note: Playing the new Riptide game on the DX2 spikes to 120 degrees. My DX2 got so warm I decided not to buy the game and uninstalled the demo.
If the firmware issues are fixed on the DX2, I will buy another.
when I'm on the car dock, it will easily be over 120. And when I'm gaming I've seen it report (SetCPU) as much as 138.

I've seen the same issues. For me, it stops giving navigation directions and locks up when it's been running for more then ~15 minutes. Problem is, the temp outside hasn't been over 85f yet.
What the hells going to happen when it hits 105f in Norcal? I don't know if I can trust using the docking station under this condition.
This has honestly gotten to the point to where i'm quite worried about my device. I'm new to android, i was previously a palm loyalist. So I'm not entirely sure what's safe when it comes to my Droid X2's CPU.
With SetCPU i seem to always be running at 100 F and up (CPU temp). However the device doesn't feel very hot.
If it helps, I'm running Go SMS pro 24/7 and using ADW as my default launcher.
Edit: Forgot to mention, I'm supercharched and debloated with Flash uninstalled.
You should be fine.

the first guy used "F" on his temp... everyone should please add C or F for temperatures... if they are in Fahrenheit then there is absolutely NO problem whatsoever. The phone "get hotter" due to the back plating being metal instead of plastic with other phones, which conducts heat better. 80-120F for any CPU is nothing to worry about and easily normal or cool operation. Now C on the other hand, that will definately be a problem. As mobiles are meant to consume less power and therefore run cooler, these temps are pretty solid in Fahrenheit, in Celsuis theres a massive difference and it then becomes a problem as PC motherboards trigger a shutdown if the CPU tops ~120C
I highly doubt everyone's phone would go to 120C...That would melt the phone.
120 c = 248 f
the phone would melt in half if that was the case......
Operating Temperature
The safe operating temperature for an ARM 11 Chips is -40c up to +85c. Within that range you should have nothing to worry about.
The battery, I do not know.
My battery temp has been perfectly fine, thank you for that detailed response.

It was 112F in PHX yesterday. I had the phone by the pool in the sun, playing pandora via bluetooth to a speaker system. Android system info battery temp read 136F and the phone was doing fine but hot to the touch. Obviously, this isn't a good way to treat your device. Normally my phone will be in the low to mid 90s indoors running audio or surfing. I did forget the phone and left it running in a car dock once in Phoenix and it was in cool down mode when I returned to my car 45 minutes later. It didn't shut down and resumed to normal functioning after it cooled down.
Wow! This thing is a beast!
my nexus one stock gets to 60C almost imediately when using google navigator.
i hear it's the CPU + 3G radio.
with 2G it's just slightly better, so i guess CPU is the main problem.
if the battery is charging it get's even worse. sun also doesn't help.
the only thing i can help is the CPU. what's the best option i have?
the tegra 2 safe operating temperature tops off at around 158°F , so 100 is perfectly safe, I wouldn't worry until you start staying above 140-145 for extended times, even when mine has gotten that high I was able to cool it quickly by taking the battery cover off and/or stepping outside in the cold air or holding it in front of an, air conditioner for a minute or two
but I only had it get that high when pulling huge amounts of data over 3g with a not so good signal, which means most of the temperature increase was due to transfer from the 3g radio getting hot as hell, I think they put the radio and CPU chip to close to each other, but once you stop pulling data or kill data connection or switch to wifi you most likely will see a drop in temp
100 is nothing to worry about

Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:
### Phone Info ###

This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

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).

Recently trouble shot this same problem for someone else. Try this:
1) Turn off Wi-Fi

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.

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.
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 did that test with my undervolted One X, after 20 cpu passes: 39,6°C
A stock One X goes up to 48°C..
seems that the tegra 3 does not get noticably hotter than sgs3. nvidia just chose way too high voltages...

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.
