Normal.

Yep, very normal. However I did find that using GPS really heated things up... next hottest is games

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.

I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.

Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies

It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%

My screen brightnes is 0%. It is hot at the top where is CPU I gues.

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

How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.

the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.

You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

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

So your cpu is not 1200 but 1650mHz now?

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

Apps that heat up SGS2

It has been suggested, that this thread is changed to show the apps, that heats up our phone.
The list is:
"Gangster - Miami Vindication" - Gameloft
"Google Earth" - Google
_________________________________________________
Hello.
Have anybody noticed that the phone gets very hot, when running a few select apps - but not all apps???
I have played a lot of games on the phone, and almost all Gameloft games without any problems, and the phone don't get to hot - it do heat up, but nothing thats worth any thought.
But yesterday i downloaded "Gangster" from Gameloft, and started playing that game. After just 5 minutes the phone got so hot, that i had to shut it down, because i was afraid of something melting internally.
I have played the game a couple of times, with the same result - which had led to uninstalling the game, because i'm just to afraid to damage the phone.
I have no other apps, that gets the phone so hot - not even remotely warm, so i'm suspecting "Gangster" to be coded badly or something like that... i'm not charging the phone, while playing - so it must be the game, thats running the phone 100%, which lead to overheating.
Any thoughts on that, anyone???...
Do the SGS2 have some sort of protection inside, so i'm overreacting - or should i just play on, without being so afraid to damage the phone???

That happens exactly the same on mine..
Gangster game from Gameloft is heating too much our phones..
I find out that Google Earth, after a while and with the 3D buildings on, also heats a lot the phone..

It seems some/many apps are heating up this phone, and some users have reported S2 going bad due to this heat. It would be nice if we can maintain a list of such apps in this thread....it would help us all know which apps to use cautiously!!
It would be nice if the topic starter can change the heading to 'Apps that heat up S2' or something like that !!

the only time my phone got that hot was when I was watching a longer flash stream in the browser. after a few minutes the (view from behind) left side of the camera became really hot so I quit the browser and left the phone alone until it settled itself.

Real football 2011 gameloft. Makes my touchscreen...untouchable!!
This is due software coding.. Some apps have both cores running at 100 % all the time..
Nice idea to list them all here and IF damage is possible to the device..

This thread mentions a few more apps:

Some of the "hot" games mentioned over there:
Sky Force Reloaded
Hot Springs Story

Download battery monitor off the market and monitor the temperature while playing these games. I've played a game that heat the battery up to 48c for a few hours and no harm was done, so I believe it has to be even hotter to make the GS2 go bad. Charging it while playing also makes it 5-8c hotter than usual.
A few games that really heat up my phone was
- Gem Miner: Dig Deeper
- Medieval Castle Defense
- X Construction
- Retro Defense
- Hot Spring Story

"Hot" is relative.
Anything below 60°C is warm, hot starts at 61 °C ................
Hey, listen ! It´s a dual core proc working in there hard, that won´t work without getting hot !
Ever touched any navi in work ? It´s BOILING !
Get a Batt Meter and read temps: 48 °C is NOT hot it´s 11 °C warmer than the body temp ........................

Mine gets warm with 10 minutes and charging and leaving the screen on. Its my first day though. Haha. Ill get back to you guys although you probably already know more than I do.

In a small device like this, it's pretty hot. Burns my hand, lol

i can play plants vs zombie or grave defense hd while charging for a long time and it gets warm not hot as expected
Robo defense on the other hand will make the phone very uncomfortable once it freezes up

I haven't had a single phone that didn't warm up when i plugged into be charged

Battery temperature meters are great, for telling you the temperature of the battery. When this phone generates heat it isn't coming from the battery.
I have only had one game cause any significant heating, Bonzai Blast. It also chewed through the battery quickly. Removing the game removed the problem.
I had the phone feel warm in my pocket once at idle. Later that day I found that the AP Mobile app had downloaded 270 Mb that morning even though I wasn't using the widget. I put the widget on my home screen, changed the settings to never update, then removed the widget. Hasn't been a problem since.

I switched my SGS II off but forgot it in the car cradle.....
When I came back it was almost melting ....
Quickly downloaded the app "mobile deep freezer" and now I can use the SGS II as ice cube for my drinks ...
......... ;-))

great thread now I know which apps are causing this.. hoping for a fix

I notice mine gets hot where the camera is, and around the earpiece/top of the touchscreen when i'm browsing the internet without wifi, i.e, 3g or H.

Same here with the Gameloft HD games, screen is pretty much untouchable.

Stopwatch makes mine super hot.

robo defense for about 30 mins makes the back near the camera quite warm, but i hear this is expected? once the screen got very hot, but not done it since...

Is your Nexus 10 getting really hot?

When gaming, it gets so hot that it makes me think "this should definitely not be this hot", I would categorize it as "an unusual amount of heat". It makes me afraid I'm going to melt something on the inside haha so I give it a break. I know it's hard to describe temperature over the internet but is yours getting uncomfortably hot?
Near the top/topleft in landscape

Mine sometimes gets on the warm side, but the Nexus 10 has safeguards to prevent "dangerous" temps (your CPU clock will downclock in increments of 100MHz until the CPU gets cooler, and then spike back up to 1.7GHz; lowest I've seen it go was 800MHz).

Download Cooltool at play store and set up what you want to show as a floating widget. This is how I monitor my cpu, batt temp, ram, wifi strength etc. This way you can be more accurate in determining wether your device is too hot and if you should be worried.

Hey thanks a lot for that! but uhh how hot is too hot for the battery?

Mine gets really damn hot as well near the removable cover. I really pondered removing the cover and back and seeing if I can make vents in the back, with a screen, then I can remove that removable cover while gaming. It's most noticeable during Need for Speed most wanted.

It doesn't really bother me, per say, but I'm just worried that its going to mess it up, but at any rate good to know it's "normal"

Normal: 70 d F
TOO HOT: 95 d F

Mine does that too. I have noticed that the case is starting to warp where the heat is most concentrated... Just to the left side by the power button. Between the power button and the camera. Almost like some glue came off and the casing is separating...

That's not good

I was using mines for google talk video chat and it got really hot. I checked the temps and it was at 91F.

Ok I did a test again and it went up to 105F. All this just by video chatting. Thats not normal!

Mines getting hot too just an hour of browsing the web and its extremely warm.

Why do you think that? It's perfectly normal for a chipset like this.

Its not just the top part thats hot like it should be. By holding it with my hands on the side you can feel the heat.

If you blast through the battery in a few hours with 3D gaming or the like the battery will get warm, too (40-50°C).

it was only like 20 minutes. I'm not saying the device getting warm isnt normal. I know that it is. However the first device i had did not get as hot as this.

The N10 is thin and very powerful so heat might be more noticeable. As long as it's "only" getting warm and not slowing down/stuttering in this state, there's nothing to worry about.

lol thats kinda the problem. the video keeps stuttering and freezing and so does the game....

everyone should be undervolting the nexus 10
this device can't even run at stock speeds for extended lengths of time without throttling due to high temperature...
it's easy to test, just run StabilityTest (search google play) and run the Classic Test... you'll eventually see your CPU throttle down from 1700MHz (mine goes down to 1400MHz every so often... i'd probably go down even more if i hadn't undervolted it)
therefore, undervolting it will help it run at stock speeds for longer

I noticed mine heating up for the first time. Don't play many games at the moment. Heated up quite a bit between camera and buttons just like others have mentioned. I was playing ingress when I first noticed. Also when I was just using browser to the ingress/Intel page. I was thinking it had to do with GPS but after reading other comments I guess CPU was working hard refreshing page.

[Q] My Galaxy S4 gets Hot D:

Hello, I just wanted to know how I can cool down my S4 while doing tasks. I know smartphones get warm but mine actually gets hot D:. After about 5-10minutes of browsing the Web or playing ANY games, or even going on apps like flipboard it gets to about 37 degrees. I would assume if I was browsing the internet outside in summer it would get to over 40 degrees. I seem to get the same temperatures even after installing a rom. I have installed an app called trickster mod and with it I have underclocked my phone and changed the governer but it still gets to the same temperatures. Does your S4 get this hot? Is it normal?

1. If u have updates via OTA or Kies/3... Update ur phone
2. Replace battery :highfive:

Do you have an sd card installed? I've read multiple stories of this device heating up while sd card is mounted, that is IF you can get this cheap pos to read an sd card. I have a g2 and a GS4, samsung really screwed up one of the only differentiating features of the phone which is ability to use an sd card.

My phone gets warm but never really hot. Is your phone in a case like an Otter Box. Is it plugged in or just operating on batteries. How stock is the phone/battery? So many questions but the bottom line is most of the time my phone runs pretty cool. I might suggest an app like SD Maid to make sure your not running a lots of juice using programs in the background, or a program like App Brain Ad Detector to see what's running and causing your phone to heat up.
They get warm but should not get hot!

S7 edge overheating

Hi guys,
I just got a new s7 edge. Been used for two weeks now.. it gets quite warm and at time quite hot suring operation like browsing web youtube checking emails.mostly the top right side and camera area. Im not sure if its a defect or not.. it doesnt get to the point where the phone shuts down but its still warm..i know the normal stuff like getting hot during charging or using the phone during charging. This is when the phone is being used and off the charger .
Simple tasks 30 to 40 degrees celsius youtube and web browsing it goes between 40 to 50 degrees. And for games it goes upto 60 degrees celsius..
Is the phone meant to be this warm/]hot ??
Please help..
I tried the normal procedures. Safe mode , format etc . I disabled apps. optimised apps etc.. still quite warm. When the phone is not in use its cool as a cucumber .

Really weird. I can play games with really sick high end graphics and the phone stays quite cold. The only moment when my S7 Edge gets quite hot is when I record slow motion video.
How is Your battery life? 4-6 hours SOT is normal. If You have less then You should check what app uses Your phone.
Also You can try first, formating the phone(data etc) and then flashing new rom with Odin. It will rewrite whole system partition.

SOT is excellent i average between 4.5 to 7 hours..
My app usage is fine..they say certain apps can make it warm.. I am using cpu z ro monitor the temperatures..
Not sure whether i should return this phone and get another one. Seems there are people with overheating s7 edges..

Well I guess if it doesn't bother You then You can keep the device..

It's a problem with a lot of the samsung phones I've previously had (S3,S4,S5,S6,and now S7 edge) on the bright side, it keeps me really toasty during the winter weather.

This is the first Samsung phone I've ever owned that doesn't get warm. Its the exynos version. I would be worried if yours is getting very hot for no reason.

It gets warm while i start using apps.. like browsing the web pn google chrome and listening to music on google music . Goes up to 40 to 50 degrees celsius..
On the other hand watchinf a video on vlc media player the phones nice n cool..

CPU can get to 80C and that's still in range for normal work, so unless it gets choppy or shuts down - don't worry. see what apps are the most battery consuming ones
