G nexus getting extremely hot

The last two days I have noticed if I run any data intensive app(i.e. internet radio) my phone reaches extremely high temperatures in excess of 115 degrees. Is anyone else seeing this? I could see this becoming a serious problem if it continues.

Yes, I have the same issue when I stream Pandora all day at work if I leave my device lying face up on my desk. Just tilt it up so the back gets some air and it will be fine. Won't get as hot.

OMG run the navigation, the thing starts to fuse iron, right near the camera area.

Only happens to me when I max the brightness, otherwise it's pretty cool.

Maybe has something to do with extended battery. I can't imagine it is good for phone internals. Have to say I am considering returning before it burns out on me. Perhaps it is another in long line of Verizon g nexus problems. Love the phone design and performance but heat issue and battery life with data on is poor

I also noticed that. Only after running it for 5 minutes or so.

Yea...still overheating to over 117 degrees when I launch any data intensive app. I can't believe this, any other suggestions?

What app are you using to monitor temps?

Same here.
Although, its not too bad. The device gets hot at the same region (top of the phone, near there camera). I've had the phone for 2 weeks now. Done plenty of research, still trying to decide if I should return the phone (if this is hardware issue).
So far, read a bunch of forums and threads with ppl saying the same thing in different ways. Haven't heard from any one who says their gnex does not get hot during heavy use. What I have read, are some ppl saying it heats up less as more time passes.
I guess ill just hold on to my phone and hope for the best.

data seems to burn this device up. Everything else i do it stays cold, but god forbid i spend 5 minutes on the internet, pops right up to 105+

I have a GSM GN and noticed my heat issues haven't been as bad since updating to 4.0.2. Anyone else notice this?

I am using battery widget and spare parts both to check temp. Yes, mine is also heating near camera area.

Shenanigans, there are going to be a lot of fried cpus with internals reaching those temps.
Sent from my Galaxy Nexus using xda premium

Same for me even after 2 to 4 mins usage..........Not impressed

When i would OC my DX to 1.45Ghz i would always get hot and as high as 127
so 105 to me is nothing
but for all you guys who think its getting hot, what do you think happens to a processor when it gets tasked heavily?

Just turn the brightness down, I haven't gotten it higher than around 100, and that's with the brightness all the way up.

Those temps are crazy. I'm streaming pandora and surfing the web and sitting at 84.2F. In the month and a half or so of ownership I haven't seen it over 105F

does get hot
Ran navigation today and it does get hot, especially with the screen on. I have a gel cover and took that off for better airflow. My original droid also got hot and i would run navigation for several hours. Never fried the phone. You have a years warranty.

I ran a little test while using Navigation, screen on, no protective case on. This is with a freshly booted phone, so no other apps running. Data is cpu temps using Temp+CPU Pro app.
Not charging: 102 deg. F
Charging: 112 deg. F
Charging and with silicon case on : 115 deg. F
I would think these temps are well acceptable. If your phone approaches 125-130 deg. f, then I would begin to worry. Surely, there is some overheat mechanism in place??

S3 getting hot when playing games and..

Hey gang.
Does everyone's s3 get hot when playing games?
Just trying to figure out if it's normal. It feels hotter than other phones I've owned. And want to know if this is common or if I should return my S3
It's really warm when using data (browsing, YouTube etc.) around 95-105°
But gets hot when playing games. Around 120 -125°
Chime in. Would love some feedback on everyone's S3.

Every smartphone I have had gets warm when playing games for over 30min.
I believe this is normal as long as you monitor and don't over clock a lot. Eventually that can kill your hardware.

today for me was the hottest my phone has ever gotten - 105F. it was 95F outside and i had to turn my screen brightness up so i could see, on top of surfing the web and chatting on the phone. someone commented in another thread that our phone can go up to 140F without issue. i dont know if thats true, but there ya have it...oh, i havent played any games yet

Been monitoring temps with system tuner under different stress levels. Playing gta3 I pushed temps to 52°C.
Internet browsing has me around the low 40s. At idle the temp is around 32-35C
My ambient temp in my home is about 73-74 F.
None the less this phone is one hot tamale! Lol

My phone gets warm as well. The temp is about average just like the rest of you guys so I wouldn't worry. Having a very thin back cover doesn't help either.

Under voting helps with this a TON. I took my voltage for 1.5ghz from 1150mv down to 1025mv and it stays much much cooler under full load. Oh and temps won't break your cpu, too much nanny software on this chip. Even over clocked. Over voltage may though =)

So far I tried playing Final Fantasy 3 on it, definitely very warm, but not hot to touch. Others include Youtube and prolong Web Browsing. Music is fine however. :victory:

The phone gets really warm on stock. The cpu has a temp control feature that if it gets too hot it will slow down. The cpu is made to work up to really high temperatures so I wouldn't worry too much about it.
If you flash to a custom kernel, they are lowering voltages on some of the frequencies and I am noticing an incredible loss of heat. My phone does not get warm anymore, at least no where near stock.

This. Like faux said some of the chips run the same voltage across many frequencies (in my case 1150mv) I was able to lower them into the 850-1050s which is crazy low. Remember power draw goes up exponentially with voltage change.

Is it possible that the American version (dualcore 2gb ram) doesnt get as hot as the international one (quadcore exynos 1gb ram)?
Mine gets pretty hot as well when i play for long times, i guess the main reason why many people are talking about this is that the Chipsets are located directly at the bottom where you would hold your phone while gaming in portrait mode for example. So you can directly feel it and the heat of your hand further warms the phone My Tegra3 tablet gets pretty hot as well in one spot - where the cpu is, but its not a place you normally place your hands, so you wont even notice that it gets warm.
Same thing was with my previous phone the DesireHD. It never got hot on the places where i held it, so you think it wont heat up at all.
In general though: I have some experience with cpu clocking on PCs and overclocking and stuff. It depends a little on the chipset of course but in general temps like 50-70° C are no problem at all for CPUs.
Workaround on SGSIII: Enable power save mode CPU. It reduces the clock to 1ghz (at least on my rom - stock jelly bean polish release), it still runs most games and UI perfectly smooth in jelly bean but it gets considerably less hot.

if i install many apps at once (testing new roms) my phone gets hot

SGSIII Heat & Battery Issues?

Background: Rooted, stock rom.
- Just bought the phone on Saturday, charged it fully and played around with it on Sunday literally just moderate texting, making short calls, and taking a couple of pictures and the battery pretty much dies by 2 PM. Will the battery life improve over time?
This is with the settings tweaked to maximum battery conservation (15% screen brightness, NFC/S Beam off, No motion controls, battery savings on, the works.)
- Also, in that time the phone seemed to be fairly hot, I cannot recall the temperature, but it was hot to the touch. And when I tried downloading the OTA update from T-mobile, the bottom half of the phone (everything below the battery) became drastically hot. But the battery remained relatively cool. Is this something I should worry about?
I'd just like to know so I can exchange the phone while I still can.

I just got mine on Friday and I noticed the same issue. It seems to get hot whenever its doing something data intensive live streaming a youtube vid or downloading a app.

Thanks for the response.
I used it for about 15 minutes this morning reading a web page on Chrome and it seemed to get warm.
Also streamed HD YouTube as well as Spotify for about 15 minutes and it's still warm.
The thing is, these are the first really data-intensive things that I have done so far.
I'm going to go through a whole day just to see what happens.
Forgot to add that I even reduced my CPU through SetCPU to 1.2Ghz the since I rooted it
It's at 87% after 2h 20m 46s on battery.
With only 42m 23s of screen time.

It should calm down after a couple of charge cycles. For battery. Also make sure auto brightness, auto sync is off, gps, motIon control, voIce cmd, etc.
I dont use the battery saving feature and get great life. But I remember a few times it getting hot after a fresh flash but it always calmed down for me. Getting warm is normal, especially if on the charger while using.
Theres a lot of features I like but dont use much so for me its worth the few extra seconds to turn it on/off.

Update
So I have completed my school day.
11h 25m 45s on battery
Battery percentage is at 57%.
I barely used the phone however.
Sent about 10 texts, went on Chrome and searched the web for about 15 minutes, took 8 pictures, instagram for 3 minutes.
Also kept getting e-mails (probably like 10 of them)
I turned on Power Saving mode as well.
Screen is the highest with 1h 32m 24s using 38% on my battery.
Would this be normal on the stock T-mobile rom with no updates?
I've never had an Android phone before so I wouldn't know.
But after researching, some people managed to be at around 70% usage by the end of the day. While doing more intensive tasks.

It's probably the service when you're inside buildings. If it's bad service it'll drain your battery.. if it's constantly trying to connect 4g you're going to have a short time *insert ski instructor meme*

At home, I literally get 0-2 bars. But at school I can consistently get anywhere from 1-4 bars.
This could possibly be it, but I am not too sure how much my signal fluctuates throughout the school.

I had given my local T-mobile store a call and they said that smartphones should be regularly heating.
It's strange to me how I can do a task a simple as texting and it heats up though.
How long did you have the borked S3 for?

I 2nd the bad carrier coverage notion. Just as a test, I put my phone into airplane mode while watching a video. I watched the same video while out of airplane mode. The battery drained faster while on the carrier's network than not. I noticed the signal meter was at 3 bars before I played the video.

Better Through Time
I decided to instal CM10 on my phone and it really did help.
I just got home from school/finished most of my day and here's the update:
63% left
9h 45m 29s on battery
1h 21m 33s screen on time
This makes me feel so much better considering that I actually used the device more today than ever before.
(HD YouTube videos, streamed Spotify, lots of internet browsing, more calls/texts.)
Even with the added usage CM10 seemed to have improved my battery life by a lot!
Not sure if I can totally attribute it to CM10 or just more charge cycles, but everything seems to be working better for me.
Thanks for all of the help!
The phone still runs hot sometimes but it has decreased over the last couple of days.

I have noticed on my phone that since installing Liquid Smooth rom has resulted in much better battery life than on the stock rom. However, ever since I have owned the phone, if i have the screen on for more than 10 minutes or so the screen gets really warm right above the home button. Anybody else experiencing this?

Same problem. I just assume that's where the processor is? It doesn't bother me. Its quite funny because the top of my screen is cold. And it doesn't get hot when I'm using it for browsing, texting, the usual. Not unless I play a game.

I'm assuming that Samsung's stock TouchWiz isn't as optimized as the ROMs that the devs make on here.
Which is a definite plus to having a device that has a strong community of developers behind it.
That happens to me as well. I have kind of gotten used to it. Just slip on a case so when you hold it your hand doesn't get sweaty and you should be fine. I would assume that's where the processor lives, but I am not too certain.

Anyone play it?
Am I the only one that gets random lag spikes and overheating while playing this game for a long while?
I've never experience lag on any game I've played in my gs3 like I do while playing this. I still manage to have fun but sometimes I have runs that are stopped because a random lag spike. Ultimately this game kills my battery both in life and heat.

I have a naked GS3 and it never gets hot but when I put it in any case or put on a screen protector it quickly boils. If you are using a case, screen protector even a battery cover sticker on your phone it will cause heat to build up as it now requires multiple layers of material to reach the outside. Take it all off and the heat should be normal again.
P.S. I just played CS Portable for over an hour on multilayer while the phone was plugged in to a car charger and there is very minimal heat. Far better than any other Android phone I have ever owned.

Average battery temperature well over 100 degrees Fahrenheit

My ion stays either just over or right under 100 is this normal cuz when I'm really using it it's uncomfortable to hold is that a drawback of the s3 cpu I'm on .29 deodexed intd smoothed ion status bar and stock home with mods any one else experience this

The phone should not be uncomfortable to hold. How are you measuring the battery temp? Two things that I am aware of cause heat; one is battery, the other is the CPU. My CPU runs around 100f-102f under normal use. If your battery is getting hot, there is a problem. My phone got uncomfortably hot the first day. I ended up doing a restore through Sony PC Companion and that fixed it. I've since had buildprop tweaks cause my phone to heat up beyond my comfort level. You either need to know your phone really well and troubleshoot the thing one by one or do a factory restore / reflash the ROM and take it slow on the app and tweak installs while testing each level of change. This is the way I do it. Other's may do it differently.

Mine is at 87 f right now just in my pocket data off but after opening this app and screen brightness at 50% its at 93 and it's only been a few minutes. I have a battery app it just says temp so I assume its my battery but anyways, how heavy you use the phone will alter its temp, I've had mine up to, if I recall correctly, 120f the phone will shut off when it's at a dangerous temp like my iPhone I left in my car to charge one summer day, we called my car the hot pocket, but the high heat shut it off and every time I tried to turn it on I got an warning and a shut off so I tossed it in the freezer. Anyways long story short, the heat you feel is how the phone keeps itself from over heating. If it's too hot for you lower your brightness that helps so much, but 100f isn't that bad for running temp

120f is a bit high for everyday use, but for gaming etc its normal.

U'll have to underclock it. 1.5GHz is hot while display on.
Lower down to around 1GHz or 972MHz. (I'm using it, to me its lag free)
