S2 Overheating, So hot It burned me!!!

I was charging my phone will in the backgorunf downlaoded a gameloft game, and i touch the phone and its so hot i cant touch it for more than 5 seconds. Is this normal, should I exchange it.

Definitely not normal if it should burn you, I've been doing a lot of background downloads while charging the unit barely warms up but there is a warmer feel but if its burning then definitely not normal.

Ok i guess im exaggerating, but literally I couldnt touch the back for more than five seocnds before it hurts.

I only have that problem if the screen is on and something is active. nothing abnormal hogging the cpu?

A lot of electronic chips have operating tempatures range of upto 90C. Since there is no fan or ventilation on the s2 all the excess heat comes through the plastic case. So when the CPU is work at full speed getting hot is quite normal.
So if it burns you like touching the side of a freshly boiled kettle, then that would be something to worry about.
That said it should not get that hot if you are not using the CPU heavily like when playing a game.

This only happend to me when I played dungeon defender. So I wont play that game anymore. But in overall it doesnt get that hot

Did you try cracking an egg on the back of the phone , if it starts to sizzle give it a quick flip over easy

Now that is true multitasking!

Having been with 3 different S2's I can say that the heat profile on this phone has a VERY huge variance. The 2nd phone I had barely heat up playing any game and that includes dungeon defenders it was NOT any warmer than playing angry birds. Charging showed a battery temperature of something like 33-34c.
The 3rd phone I got charges to something lie 41-42c and runs significantly warmer even by just playing Dungeon hunter2 HD.
There was a mythical phone even that ran at 1.6Ghz overclocked and it ran cooler than stock, now that was some cool story!

I'll experience the same thing when playing live holdem poker... The temperature rise up to 49C..

my phone went up to 60c while playing Dungeon defenders for 20minutes , and it doesnt restart, anyone know the temp threshold? and should i stop playing the game ? XD

finally i solved this problem using tegrak to set cpu speed to 200 min : 800 max
no heat any more
but i need to ask is it safe to change it in games only and return it normal all other times ??

I remember trying Google Earth with 3D buildings for a few minutes.
Phone heated up and scared the hell out of me. Never going to run that again.

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.

Tablet Over heating

Hey Guys I'm just wondering is anyone else has encounter this issue, I play Call of Duty Zombies and Batman The Dark Night Rises and after maybe an hour or so My tablet really gets hot.. is this normal? I'm currently using PA with Trinity Kernel. but I had the same issue with other AOSP Roms...Carbon, and CM.... any info is appreciated!!

It is normal. My tablet gets hot only by browsing online.. All nexus 10 are getting easily warm. The problem is if the tablet reboots often for that reason. So, don't worry it is normal.

May be I should've said Real Hot... I mean. I don't get any reboots from it but it does feel Way above just warm.... Maybe I'll Download a CPU app to watch the temperature and the post a screen shot..

My tablet gets hot enough when browsing the internet.. I think that if i try a game, the tablet may explode .. So i think it is normal. But to be sure check the temperatures..

Try to stay in one of the other million threads on heat issues: it's not "overheating" unless the device goes beyond operating parameters and shuts down/reboots anyway. "Warm" is pretty subjective, but the hard limits that the CPU has built in definitely aren't.

My tablet gets hot while playing games or browsing but never a reboot so I think it's normal.

It gets hot mainly at the top-left for me, which I'm assuming where the SoC is located. Not too bad if you're holding it normally.

does your S4 get hot below the camera?

Hey guys,
i noticed my phone was getting a little hot while i had the navagtion app going.
im using the S4 flip cover and right under the back camera, where it says Samsung - I felt the phone getting hot.
Anyone experience this?

Me too

It's always hot.
I mean it gets hot often.

Of course it gets hot because the CPU is right there.

yep i think gpu too because when i play for some time some big games its so close to hurt the finger on the screen side too
expecially if its under charge

According to the manual you shouldn't be using the phone at all when charging

Loool really? Its always under charge when i play or the battery drops in 2 hours i disconnect sometime when it become too hot
Sent from my GT-I9505 using xda app-developers app

Using while charging is fine unless it is overheating.
The reason it's recommended not to use the phone while charging is because it reaches high temperatures much faster and so is more likely to overheat causing hardware problems
I personally don't game while charging since this phone (especially i9505) gets really hot really fast

yes i know that heating its very rapid while under charge..expecially now that its so hot during day and cant dissipate...in may when i bought s4 had less problem
i think i must think to buy an extended battery to play more than 2 hours hehehe are they already on stores?

Almost every good phone gets hot now and then. My rooted S4 barely gets hot. I mean i flashed a great rom (omega rom) and flashed an amazing kernel (perseus) and played a bit with cpu voltages and i undervolted my cpu and it barely gets hot , and when it does , it does not get very hot .

i tryed to underclock processors but,maybe i just made a mistake, i saw the battery drop much faster...i setted max speed at 1.2 last time but never tried again

OMG, OMG, OMG, finally!!!!:victory:
I thought I was going crazy, but YES, the phone gets unusualy hot just below the camera.
I noticed this right after performing the Apps2SD update, and since then have been freaking out!
I am afraid that constant heating and cooling of this kind can damage the sensitive parts inside,
so I have been limiting my use of the phone in the last few days.
People, this is not normal. Somebody needs to contact Samsung.
There must be a software patch for this...?!

Oh yesss!! Let's make another thread about overheating -___- It's already known that this happens, so you better get used to it.
Me Gusta!

Does This Phone Get Hot?

I've read lots of comment about the N4 getting hot under normal use. Is this still the case or has the issue been addressed. I'm seriously considering buying this phone but I don't want a phone that gets hot.

Mine hasn't gotten to hot.
Those reporting this problem are probably a minority of all nexus 4 owners.

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

Thin glassy phone + powerfull cpu = heat Nothing to worry about.

It gets hot, at least on stock firmware, although my definition of hot might be more sensitive than others. I don't know what it would be like talking on the phone for an hour with it getting hot next to your face, although I haven't done that. I have to use custom rom and underclock the cpu a bit, so it's not an really issue anymore. I probably will get flamed for this, but I don't recommend this device to you if you don't like phones getting hot. But I guess lots of these newer flagship phones that has thin plastic casing probably gets hot too.

With normal usage the phone doesn't get too hot or anything. If you are fond of overclocking and disabling thermal throttle you will get pretty high temperature's. Around 70 degrees celcius.

It get's hot as any other phone but because it has got a glass back you feel the heat better.

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

Yes very hot, don't buy it.

Yes it gets very hot but the thing is you can still use it without getting very hot if you play games then yes it will get hot.

Is your phone undervolted and temprature limited?
My temprature never goes over 40 degrees celsius, and feels rather cold most of the time.
Even with rather intensive games like NFS Most Wanted

This phone will not burn you. There isn't a real reason to consider the heat a problem. The temperature of the phone is regulated by the kernel, if it gets too hot the kernel takes measures to reduce the amount of heat being produced. This is a non issue.
