over heating

thought I'd already seen this discussed on here somewhere but can't find it now when searching.. I've been having problems today with my phone getting quite hot around the top of the screen.. I took the battery cover off and it was noticably hotter just to left of the second mic (as viewed from the back)..
anyone else have this, and do you know what components are in that part of the phone?

I have this issue when i play games etc Don't know the reason though

I had mentioned this before...but most people replied here saying that it was normal....mine goes upto 38-40C while playing games...

It's probally the cpu that is there. All the phones are heating and that the arc is slim you feel it really quick. Nexus is heating when using GPS navigation.
But i agree the arc is heating really quick.

smart phone are ****ing laptops these days, does your laptop feel hot when you play game?

my phone was fine until today.. and it's only hot in that specific area.. not playing games though.. just surfing, facebook, xda..

Mine does the same, happened since day one, it wont be anything to worry about (I dont think)
If your worried about it overheating you could return it to where you got it from or even install setcpu and underclock it a tad.

same here, especially when surfing net
in my workplace where signal is not that good, that particular back area of the phone is hotter than when i'm at home. i'm guessing the 3g chip is in that area of the phone, not really sure though

This happened to me it is extremely hot when playing games and abit hot when charging I rang my network and they said they have never heard that it overheats so they replacing my new phone in the morning hopefully they come

If you are surfing internet, many flash ads may result in over usage of CPU and making your phone hot. Bad programing with flash which happens when companies hire cheaper developers...

Mine gets warm fast too... during navigation, game or downloading apps with 3G.
The processor area needs to dissipate heat to the outside surface and maybe since it is thin and plastic, we feel the heat easily.

Arc is a Hottie and hence it feels hot LOL.
I too experienced this, specially when charging and playing games. X10 gets hot in the battery area and this gets hot in a different area.

Well just received my phone lets see if anythings wrong with this 1

Galaxy S II very hot

Hi.Is it just my S2 get hot when I play games or use GPS? Especially at the top around the camera.

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.

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..

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.

Phone gets super hot after 2-3 mins of gaming

So I've been playing Arcane Legends rpg game , the phone gets hot on the top back of the phone . Anyone with the same issue ? Gets even hotter with a case on it's ridiculous Phone is completely stock 4.2.1

It happens. It happened to me just today.

How much is "super hot"?? Install the app called GS Battery Monitor and see the temperature of your battery. If it is more than 40 then it's something to worry. Or else you are good.

Seems pretty normal, screen is on, graphics are cranking, its an online game too right?
Best you can do is if you were to be rooted you could try underclocking to limit the CPU, or limit it to less CPUs, from getting that high so it doesn't produce as much heat, or really as easily.

My phone did the same thing. It got very unbearable to hold. My solution was to return the phone back to LG/Google for a refund.

Stock kernel? No wonder. Even mine gets hot after browsing. Fixed by installing a custom kernel.

[Q] LG G2 Operating Temperatures

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.

I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.
-LG G2

I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

I was actually looking at getting the dual pro. Thanks for the feedback. Exactly the type I'm looking for.

Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out. Loving this second one

Does anybody know if we can track manufacture/release date using the serial numbers?

I am using this case full time: http://goo.gl/0u05G5
I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

yeah, especially while gaming.. and it's not the battery drain that concerns me, the heat is ridiculous for long term gaming..
and slapping a case would be good for your hand but not for your phone
plus there's not one manufacturer that make cases for heavy gaming yet..
i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

One thing I've noticed from people's screenshots is that the screen doesn't use that much battery. My RAZR would sometimes draw 46%. I'm sure that also contributed to the heat. smh.

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.
If you'd like to give input shoot me a pm and we can discuss it further.
OnT: I very rarely pass 24c on mine, then again I never game on my phone either. Highest I've hit was 42c during some testing.

Are you guys talking about battery temps or cpu temps?
Get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.

I have made the tests , and i get 72 °C after 1:20 secs running the standard test. About 35 °C in idle,and about 50-55 °C when i am using the phone for facebook,browser,youtube. Is this ok? (These are Cpu Temps).

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?

Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?
