Processor gets hot

I'm concerned that the phone gets too hot when playing games.
Sometimes just browsing the internet causes a warm spot.
The hot spot occurs on the top corner on the left side.
I'm wondering if the phone is going to last 18 months if it goes through this cycle on a weekly basis.
What do you think?

the problem is that some of these games can be a bit demanding and considering this GN uses a Omap 4460 CPU it's no wonder that it's struggling.
it's a shame this phone didn't get one of the newer Omap 5 series.

Not so hot mate... you havent owned a GS2 to witness the real hotness

Welcome to Smartphones, all of them get warm or hot when playing games on them. If you tax the phone really hard it will get warm/hot as well. Regardless of what CPU they have.
It will last perfectly fine, dont worry about it. Think of it as a added bonus, a hand warmer.

or if you're female and it's that time of the month(cramps), it doubles as a heating pad for that area.

[Q] Galaxy Nexus really HOTTTTTT!!!!!

I don't know why is my Galaxy Nexux (Sprint) has been getting so hot. I unlock the boot loader and then root with SDK . I installed Cyanogemod 9 and I like to play two game in my GN Bat Walk, Briscola and there where my GN go's up getting as up to 129c. I tryed some other roms and kernels but no change. I'm right now with Paranoidandroid. Any Help will be appreciated.

You ever try using an app like setcpu to check your MHz settings?

129C? As in ~250F?
I think you're a bit off there, but make sure your not downloading anything over mobile data.
Playing HD video makes your GPU or CPU (based on rendering methods) hotter. Sometimes very hot to the touch.
If there's a evident dip in battery life, then it could be an issue with the CPU running when off.

i regularly reach the automatic shutdown/safety temp of 110C, by choice. at that temp the cpu shuts itself down. 65C is well withing the normal range, and well below the throttle temp. feel isnt a good judge of temperature. feel is relative. try this experiment and you will understand. take 3 glasses of water, one hot, one ice cold, and one room temperature. put your right hand in the hot water and your left hand in the ice water, for several minutes. now put both hands in the room temperature water. your hand thats was in the hot water will feel like its in cold water when put in the room temperature water at the same time. your hand that was in the ice water will feel that the room temperature water is cold. if the air around you is cooler, the phone will feel hot, if the air around you is warmer, the phone will feel cold.

[Q] Heating Problem

The top portion of my phone gets headed up. I am facing this problem from last one week.
Initially my phone used to stay cool even if I played games for hours. But now the top portion gets heated in just 5-10 mins if I play games.
Is this normal??

How hot it is?
since you said it did not heat up before this it's probably an issue you have to solve.
since the day I started using Samsung phones I never experienced during games.Only when charging
Contact Samsung and see what's their view on this.

The processor is probably located at the upper part of the phone.
After some time playing games my top part is getting a bit warm. My temperature is not that bad, nothing to worry about.

Stuffing a quad core (!) processor into a several mm thin phone will cause heat. Nothing to see here, just doing it's job.

Not experienced heating issue at all, the might be faulty.
I have had 2 not had this proble might be worth getting replacement.

If it gets hot without doing anything, only then it can be faulty or else while using it hard is understand able. My s2 used to get hot from top, s3 from bottom and now note 2 from top while playing hd games. Not a concern for me as it gets back to normal very soon

I suppose it depends on the severity of heat and what apps or functions are running. If it's gaming for long periods then perhaps phone may get heated but like I said I haven't experienced this myself.

The only time I've noticed my phone get hot is when it's been in my trouser pocket...but then that's a pretty hot region anyway. :laugh:

I switched off quick glance about an hour ago. The dim red light of the sensor has turned off now. Played a game for about half an hour with no heating problem.
I think it was the quick glance which was causing the problem. I also removed open s voice via home key.
Can someone please confirm whether quick glance can cause this problem.

36º it's a very usual temperature, it's not dangerous. If you want, you can downclock your CPU for a lower temperature.

are you using the original charger? or original battery?

Yes I am using original battery and charger. Now the temperature stays around 32 C while playing games.

I was playing zombiewood and my note 2 was peaking at 37c.
I think it was starting to affect the game a bit as the left joystick over the hot part would sometimes get unresponsive. Might be coincidence tho.

While playing local its only your GPU/CPU that does the work, while online your radios are also working. Almost all parts of the phone are working. So its normal. Also if you are on a long call(~30mins-1hr) your phone may heat up in that case too.

Regarding the heating problem I wanted to ask this, the back gets hot cuz there is no ventilation for the processor of the note 2. Now the question is I got me a back cover silicon from sides rubber on the back does this affect any small ventilation or heat transfer that was happening? I know it does affect cuz I feel a warmth on top but not hot as b4 bcuz of the back cover now. Does this affect or may reduce the performance of processor by time?

The phone has a quad core processor (lol) which is passive cooled. To make your answer and the story very short, you don't need to worry about how hot it gets.
On a side note, I had mine tested from full power till it went off, playing nfs and it got as hot as....imagine pouring hot water in a can to make a tea and let it cool for 5 minutes. You can barely keep it in you hands...well that's how hot my phone went and yes, I play nfs still daily for about 1 month now, still works like a charm.
Passive cooled BGA's (processors) can go much hotter than a normal cooled component. And if it reaches the extreme it should shut down itself, with another words, heat isn't your issue unless you play NFS for 5 hours directly under the australian 50% sun melting the phone

mmmmmmmmm does your screen getting hot also, because mine became hot after 10 mins of playing NFS or Asphalt especially its top half I´m afraid that will damage my screen :crying:

totally normal
the exynos chip is located behind the camera ( top of phone -centered- ) so its normal the top back of the phone will heat and the top half of your screen...what do u expect from a processor with no fan? normal!

Well thanks I just wanted to be sure that's all.

You realize 104 F is not hot... at all.....
1) Laptops and have had electronic components built to withstand up to 100 CELSIUS for years. I'm sure your phone can handle 40.
2) If you can't talk on the phone because a little warmth is too much for your sensitive skin move the **** to Alaska because 104 is not hot by any stretch of the imagination.
3) My phone has no lag.... at all, so I don't know what you're speaking of. I can play NFS:MW for an hour, switch to Eufloria HD for another, then hit up GTA:VC for an hour with absolutely no problems. I can also scroll through the drawer faster than my S3 could respond, so it is much more responsive. Maybe you got a defective unit or you messed it up somewhere rooting or flashing roms or poking around where you shouldn't have... I mean based just by your grammar you're not that smart of a person, so I'd say user error is MUCH more likely.
4) If by the blur you mean the purple when you're in the settings, well yes. You've got me there. That is a minor bug that needs to be addressed, and will. The phone has been out for like 11 days bro, give them a ****ing minute.
5) No, sir, your Note 2 is not faster. Yes, it has a larger screen and slightly better battery life, but faster? No. Run a CPU and GPU benchmark and try to tell me its faster.
Give them some time to work out the kinks in the programming. This is how electronics work, nothing is ever going to be perfect when its being produced by the millions on a short time frame with 6 different versions for different countries with different hardware and 10000 different carriers trying to poke around and make their own adjustments to the software.
TL;DR: Stop crying, you're embarrassing yourself.

I hate when people say use benchmark look which is faster... man everyday use is what matter, when I'm playing games and my note 2 runs them smooth and my S4 runs them choppy there is an issue I'm sorry there just is. Now for 104 degrees being not too hot, wow really its beyond hot for a phone to hit, don't give me the whole laptop crap this is a phone that people use to make phone calls and the screen and the back just feels way way too hot. Just use the speakerphone what are we Apple "You're holding it wrong" come on guys give me a break a 670$ phone should not have all of this stuff going on. Then you're telling me oh download an app to fix the screen issues -.- , you guys may think this is over the top i don't think so when you buy something so expensive and it works so iffy, don't get me started on Shealth love it but keep restarting your steps all the time ... might as well call it Srestart ..... oh samsung i love you but you're killing me with this phone. I'm getting a replacement on monday I'll let you guys know how that one is hope its 100X better....

No, 104F is not too hot for a phone to hit while charging and being used. You have heat from the battery while charging and heat from the processor while using, add any case you might have put on there trapping the heat and it is still well withing acceptable parameters. In Florida ambient temperature reaches that through most of the summer.

104° F is actually cool for a phone th that's charging and in a call. If the device is lagging out on you just return it if a reset doesn't fix the issue.

I actually had this same issue on a white 16gb s4. Phone was powered off while charging over night. Upon powering it on the internal thermometer also read 104F. I suspect it was much hotter, given I have hot spots on my laptop case that reach that temp as verified by a thermal camera. This felt much hotter, though I didn't have the tools on hand to verify.

I've heard a few people complain about their devices getting too hot, but most of them have had the white version. Is that what you guys have had? I have the black one and haven't experienced this issue at all. It does get a little warm when charging, but other than that, no issues here

Well I'm in Florida so whenever I'm inside it's like a warming pad against the AC. When I'm outside I don't care because it's not getting any hotter than the air already is. Sound logic.
You do realize I was being sarcastic right? Regardless, that's neither here nor there. You can't make a thread and be like "Damn samsung my phone hits 104 F when I'm charging and talking on the phone!!!!111oneone"
That's not hot. Especially for a phone that's charging while doing anything, or using mobile data in any way, or playing games. When it hit's 60-70 celsius start complaining about overheating problems/return it. When your phone hits 100 degrees Celsius start worrying about the internals frying. Anything less than that stop complaining. It's a ****ing quad core computer that fits in your hand and is slimmer than a BIC lighter. Of course it's going to get warm. If you didn't realize that when you bought it you shouldn't be paying 650 bucks for anything because you're too stupid to have 650 bucks to spend.
For the last time, that's not hot at all. This thread is pointless. I'm done with it.
