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...

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.

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 again dear xda members
I've been using S II for over 2 weeks now! I get the following(which many of you do get also). When I turn on WiFi and start surfing, the phone starts to overheat and battery is drained like a juice.
Well, after a long study, I've found out that it's the stock browser's fault!
Yeah! I opened WiFi, surfed a little and it started to heat up! Well, I was trying to download something, and since stock sucks at downloading( except if you add to it an app from the market called Downloadfiles) I opened DolphinHD!!
What I saw, or felt-whatever-, was just
After 5 minutes, the phone cooled down, temperature became normal and of course battery was less consumed!
So, to all people who have heat issues, it turns out(at least in my humble opinion) that it's the stock browser's fault!!!
Any thoughts anyone? Similar experiences?
I've been using it for 10 days and experienced no such overheating, but battery time should be much better.
Sent from my GT-I9100 using XDA Premium App
Really? It doesn't overheat never? even not when playing games?
I thought mine was faulty, but I went to couple of stores where they have it open for customers to play with, and I did the same as mine and it started to heat up!
Mine heats up a bit after playing a game or running a certain app for a while, but I never experience overheating with the stock browser. Though you should take in to consideration that the GS2 is a thin device, the CPU is close to your hands. Most phones also have to exessivly keep searching for connections because it is weak or something is blocking its way. The transmitting/receiving device is located at the top along with the CPU so it'll tend to get hot. Most smartphones do overall.
Also, the phone gets hotter while using it connected to a charger just because the battery is filling up the same time you are using it. Also, take in to consideration that no patch for true dualcore support has yet been released nor announced. Just some factors why the phone heats up.
thanks man!
Well, heating up is normal-as far as I read in here-... But when using Stock Browser, I'm talking about overheat! really! I believe it's a bug, since as said, nor Firefox, Dolphin and Skyfire(I use all of them) produce that issue! And I disabled flash content(thought that might make it better) but it was the same! Don't know!
Anyways, thanks for answering!
OVer wifi I have no problems. Over 3G is another story! and playing games is another story. It warms up every 5 minutes while playing games.
Yours too huh? well, mine does that on WiFi!
What is Overheating? How do you know it is overheating unless you know the temperature of the battery? Well OP and other posters who are saying the phone gets overheated please mention the temperature of it. The ambient temp of Europe/USA is 20-25°C Max, and if the device runs even cool then it will have temp around 30-32°C, that is much higher than the ambient temp and probably that's why you guys are feeling the phone is overheating but in fact it's not. Here in Calcutta, ambient is 32-33°C and the Phone temp in normal is the same, so we/I don't feel it's overheating, only when I surf net for an hour straight with charging then the temp rises up to 44-45°C, that's when it could be said that the phone is running on high temp, still for the hardware we are given 45°C is not hot.
So before saying the phone is overheating please check the battery temp.
Regards.
how do I measure battery temperature?
Ok, Battery life widget?
I'll measure then I'll let you know!
There is a reason stock browser uses more battery and heats more. It uses GPU to render pages more quickly! But for me even on stock it is not that hot, more than on other phones, but thats what you get for a thin phone.
Maybe somone will test battery life with stock+GPU and dolphin browser with no GPU. Maybe the difference is not that big at all, maybe just GPU heats more than CPU but uses same battery.
now let's not forget android doesn't have graphics acceleration, and without it the GPU has to work harder which generates more heat

Summer in Greece and sub-30-degrees Celsius don't go together.That's why we're hot!
Anyway,****ty joking aside,inside a bus today,under the sun with an ambient temperature of about 35-36 degrees(dunno how you put the degrees symbol pal ) and with my GPU overclocked at 400MHz with 1100mV using tegrak overclock ultimate,I played some Angry Birds and,although the phone reported no more than 44 degrees,it was very hot at the top.
My opinion?If you(or me obviously) manage to somehow burn/fry something,make sure to do it so bad that it doesn't even respond to Chuck Norris' roundhouse kick! That way maybe Sammy won't notice...Shush!

Alt+0176.
Funny comment anyway.
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 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.
Has anyone experienced that the phone gets warm ( between 30-42 degrees centigrade) even when doing normal tasks like browsing the Web/the screen simply being on? Is this normal? Is there a fix for this if it is not?
Thats what i hate on my Z.... so you telling me Z2 has the same issue?!

You'd enjoy using the HTC One X then, normal use it easily reaches 42ºc, extended use and/or heavy use can see the phone reach 55ºc so for me, that's a welcome change.
I should be receiving the Z2 tomorrow anyway so I'll post my findings then.
I have noticed this also. I downloaded about 3gb of games and the top back of the phone got fairly hot

Water resistant coating will always trap more heat inside, maybe that's why Sony uses the slightly lower clocked SD801.

I think that would be a reasonable assumption.
I guess the only question is whether it's a deal breaker or not.
Does increased temperature effect battery life at all?
I noticed this happening recently but on rare occassions. It gets hot right where the camera is located but I'm not sure if it is related to the camera or some other app. I know that it overheats when recording 4K videos over 3 minutes. The quick fix when it heats up is to restart the device so to me it is definitelty software realted.
Mine gets warm, but not got enough to be a problem so far. I'm in the UK.

Coming from the Galaxy Note 2, when my phone got warm it indicated that there was a problem. Maybe since this is part of the design, with the waterproofing at all, I'll just have to learn to accept that the phone will get a little warm.
On the plus side, it'll be good for the winter, to warm up the hands

Most definitely.
Well i can asure you that all snapdragon 800 soc overheat and it depends on what you do,my curent device lg G2 when i bought it,it had jellybean on it whne browsing web listening to music etc it always got hot,but when plating games it was a very big overheating ,the procesor got up to 72`C ad baterry was on 42`C and i thought it was a problem with the phone but after updating to kitkat all problems with overheating where gon even in graphinc intense games it took the phone 30 minutes to heat up significantly + on a side note the battery got a lot better i managed 4 hours and 36 minutes of screen time.
Botom line its a software problem coupled with the nano coting(it blocks heat but not in a bad way that the phone will overheat from that maybe a 5`C block).
Overheating is the reason I didn't get the G2.
It overheated doing basic stuff.
It can't be fixed by software. LG certainly didn't release a fix, so don't expect one for the Z2.
When a phone has overheating problems then it will always have it, just like a laptop or any other hardware.
You'll have to deal with it.

Well not really my m7 used to get warm / hot with 3g or gaming up to 42c after sense 6 it refuses to go above 35c and when gaming up to 39c , so far only known phone that doesn't get hot is the m8. Imo it's tolerable for z2 to stay warmer then other devices , glass isn't the best option for cool phone + sealed phone due water resistance.
Btw yes warm / hot phones have shorter battery life due heat issues , warmer battery = faster discharge rate.
Imo if z2 gets hot only when gaming it's fine, all phones get warm but if it's crossing 37/38c up to 40+ on WiFi and normal usage I'd call that a problem. You can forget the gaming if this is the case lol , at least stable gaming without fps loss and throttle.
The overheating when using the camera is a bit of a concern, especially since that was one of the main reasons i bought the phone.
Is it definitely software related or hardware?
As if its software i can wait for a fix, but if its hardware then i'll need to swap phones
After reading other device forums seems like all the Snapdragon 800/801 devices have the overheating issue: SGS5, Z2, G2, etc.
I think it's because the new SoC is so powerful that it generates a lot of heart, especially when gaming.
Maybe the 805 will fix this. Not gonna buy a device with 800/801 because almost all of them have overheating issues.
Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

The only benchmark that matters is the one between your ears. And according to you, it passed.
in actual daily usage I find nothing to complain about

All others are a waste of time.

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:
