does anyone else is nexus get really hot when surfing the internet or doing anything else. I've only been using the phone for 15 minutes and it's already dropped 10 percent. idk its up to about 118 degrees
is this pretty common with this phone?
Clock speed
Usage
Screen brightness
Those affect how your gets.
Are u an aggressive user and clocked it up high and always have high brightness.
No only 15% brightness no over clock. New phone just got it today just seems to heat up asap...and gets over 110 degrees easily. The of course causes major battery drain. Prob normal for this phone just never experienced heat like this before
Isn't the processor on the Gnex designed to do a panic restart when it reaches 110 C's ? :/ yes its a big issue i've noticed that the phone doesn't get that hot when using stock Rom weird...
I don't get over 110 and I'm OCed to 1.3gHz, auto brightness on.

The only time mine gets abnormally hot is during a phone call. Im even underclocked and it still does.
getting hot in a smart phone this powerful is normal. I had the S3 for week, that sucker gets hot!
I agree with OP. Mine gets noticeably warm when scrolling through large non-mobile web sites. It cool when scrolling through apps like tapatalk, market, reader apps. It must be something to do with browser engine
Mine gets quite warm as well. Especially with games like gta 3 and Final Fantasy 3.

please don't forget that you're holding a device with a dual core CPU, clocked at 1200 MHz, without fan, water-cooling or anything. ever tried touching a computer-cpu?
(don't do that, lol)
Mine can easily get to 110 degrees. It definitely has a heat issue. My Razr Maxx can get warm too, but not hot like this GNex. It hurts to palm sometimes !
LTE / Camera / Data stuff . / Charging all contributes to this.
Thank god it has removable battery, since battery life will be significantly dampened by heat.
Mine gets hot since Jelly Bean... Maybe "project butter" is intended to melt our phones like butter
remember, battery temp and cpu temp are two completely different things. cpu temp will get lowered automagically in the gnex when it reaches a certain point(heat throttling is enabled in the gnex, unless you disable it), and it will shut down the cpu when you reach 110C, not 110F, that is a safety feature. 110C is 230F btw.
This summer, I bought this phone but sold it after a week because it had a ton of problems, including overheating. Today, I bought the phone again, because I wanted to give it another chance. Right now, in the middle of winter with less than 20C in my room, I was playing Temple Run when I started noticing the phone was getting warmer. I thought "well, this is normal, I have been playing a 3D game for about 20 minutes, I bet it hasn't overheated like it happened this summer, that one was probably defective too, it's just getting a bit warm, that's all", but guess what? I quitted temple run, ran a Quadrant session, and yeah, it had overheated and reduced its performance like it happened last time. Halved performance due to overheating, exactly like it happened this summer, 3000 points instead of the usual 6000+ it gets.
I. CAN'T. BELIEVE. IT.
I guess it's my fault though, fool me once, shame on you, fool me twice, shame on me.
This phone is such a piece of crap it gave me the most buyer's remorse I've ever had.
6000 points on Quadrant? The max I got was around 3400...
Anyway, I think it is normal to a device to overheat and lose performance when it gets hotter. Same for too cold (under 0ÂșC). The colder, the better the performance. That's why all eletronics should be kept cool.
I could have excused it for overheating during summer with 35C room temperature, but with less than 20C and after just less than one hour?
How is this acceptable? Seriously, what is wrong with this phone?
I am raging uncontrollably right now. I can't believe I was so stupid to get this turdphone TWICE before realizing it was indeed a massive stinking turd.
And yeah, it's not 6000 points but 3500, when it overheats it gets much less, and I notice it's happening even before the score gets displayed, because usually the planet thingy runs at 60FPS but when it's overheated it runs at around 40.
GOD DAMN.
Oh and by the way, if it overheats during gameplay, it also overheats during web browsing or EVERYTHING really. And EVERY SINGLE XPERIA S IN EXISTENCE has this problem. Yours too.
You better not use it too much, or it might overheat and start running slower than a X10. What, you bought your phone to use it? LOLZ.
/sarcasm
definitely rom/kernel problem.. what's rom u use? have u update it to latest .55? u unlock the bootloader? u just b*tching without give any details.
the colder the hardware is not the better the performance, there's something called operating temp. usually u cant use the hardware if it's not in its operating temp (like PC processer, it cant boot when 0 degree Celsius, but booting fine at 30 degrees or -27 (subzero) degrees). if u get lower performance, usually it's because the driver/applications that order the processor to lower itself.
when i was using custom stock rom, i've played Nova 3 with my friends (wifi) for around 45 minutes, and it hasnt got lags, sure the phone was very hot, but the performance wasnt drop. now im using cm10, still got no lags when playing games (Trial Xtreme 3 is very fun & challenging and surely a phone heater, ive spent bout 2 hours playing, got low battery, charging it (thx for the fast charging) for 1 hour and half, then playing it again.. still got no lags )
so, surely the problems is in the rom.. since ur in xda, try fix it urself... if u wont, just f*kin' sell it
About overheat on my phone, yeah it does sometimes. During summer it can get up to 40C (the ambient, not phone), the phone overheats while using for browsing, but I think it's normal.
It gets hot when playing NFS:MW, the performance drops but I just have to leave there for 30 min and its good again.
The phone generally gets up to 43 C when playing...

Dude. I'm playing it in my room, with 17C room temperature. After less than one hour of that crappy game Temple Run, the phone got hot, and out of nowhere I decided to test if it had clocked down like it happened during the summer, and it did. I'm fully stock, locked bootloader, stock rom with only some bloatware removed. As soon as your phone gets hot, try to run quadrant and you will see your performance will have reduced. I think you can also see your CPU speed has gone down to 800Mhz.
And by the way, like I said before, I'm on my second XPS, and the first one also overheated, so I guess they all do that. I think you may have noticed the phone becoming laggy after some heavy usage sessions.
Anyway, I am not sure if every phone somehow clocks itself down when it gets hot and then starts running like crap until it cools down again, but on all the phones I've used in my life, this is the only one that does it and after such a short period of heavy usage. It's just ridiculous, there should be class actions up sony's ass for this, but it seems like I'm the only one who realized this happens and literally cripples the phone's performance until you stop using it, basically.

If the phone kept at full speed, it would heat even more at the point of damaging the internal components.

I am not retarded, I know how overheating works, I'm an IT technician and I deal with overheating bleeping computers all day long.
The point is, the phone SHOULD NOT overheat and clock itself down to half the speed after just a few minutes of gameplay. This is ridiculous.
Why are you missing the point?

It overheats, and it should, because you're running a 3D game. Again, it clocks down to avoid bigger overheat and damage. My phone performance keeps the same after 1 hour of playing NFS:MW. It just need a few minutes to start the processes again, since the game use it all.

The thermal throttling kicked in so that's why the OP seeing lowered performance.

OP, buy another phone then, problem solved, you're welcome. :good:
God help you it you bought a S3, but seriously time of year is not gonna change a overheating issue and 35-40 is the ideal temp for optimal performance
And I know 4 people in IT, and their knowledge is pretty much on par with yours judging by your posts

Of course the phone should get hot, and if it does the CPU should def do something about it and underclock
Also why do you have to swear so much? girlfriend problems? limp noodle?
also if ur going to buy something to test its gaming prowess, buy a psp or something
my advice? stop being a moron.

thats not permanent, its the app staying in cahced processes just in case it needs relaunching. try ending the process and try benchmarking again
you find removing it from the ram as a process may help
i just ran quadrant on mine
its warm cause im playing music and have tons of crap open. it hasnt slowed down. and its score was 2937. i dont see the issue though? the number means nothing on its own. its a potential comaprison tool

Pffft. Do you even know what you are talking about? It SHOULD NOT overheat, only heat up a bit. Playing a game or doing anything CPU intensive should not OVERHEAT the phone, only heat it up a bit. There is a difference between heating up and OVERheating. Overheating means there is something wrong with the cooling solution, and should not happen unless the cooling system or the chip itself (this case, since a cellphone doesn't have a cooling system) is faulty. Learn what 'overheating' means.

You also have trouble reading and understanding basic english. If I play a game, then quit out of it, and then run quadrant and I get half the score, there is something wrong, that being the CPU clocking itself down to 800Mhz (instead of 1500) because of overheating. OVER HEATING, not simply heating up. Over heating is NOT normal. If I only had too much stuff open, the CPU wouldn't have clocked itself down to 800Mhz, it would have ran at 1500 but with reduced performance in quadrant because of high memory and CPU workload in background stuff.
Anyway, I'm done with you guys. Educate yourselves on how processors, operating systems and electronic devices work then come back.

It's 45 nm, dual core and 1.5 gHz. ofc it got hot. But not overheating. When the hardware is overheating, it'll turn off, u should know that.. I said again, it's the rom/kernel that asked the procie to lower itself when in some temp. mine? I never have this problem since in cm10. Read my posts again. And surely I benchmarked over and over again (antutu) and the scores are vary, but not very much (I even got Max scored at my fifth try, the phone was hot though, but it was alright)
And if u search about xperia s overheating, there are some talks (even here in xda) bout performance hits, etc.. but it was way back there... I thought ppl already learn how to handle this... well, I thought wrong.
Ang if u thought the phone is hot, try playing with HTC one x...

Please suggest me the ROM and KERNEL and MODS.
I play Clash Of Clans and need good camera.
My phone is getting hot within 5 mins of browsing,
If I'm playing games , its temp goes to 74 C instantly..
I'm not able to talk for more time bcoz of heat..
I'm getting around 2.5 - 3.5 hrs SOT.. 5 months old phone.. Battery is not bulged.. So I don't think battery problem..
Using Greenify, Rooted.
ROM tried :
1. Resurrection Remix.
Phone getting hot (MAX hot 74 C) within 5mins of browing.
Clash of Clans lags.
2. Euphoria :
Its not getting tat hot compared to RR ROM.
But Clash of Clans lags.
When I connect F&D 2.1 Speaker through 3.5mm jack, my phone doesn't detect the speaker. It detects Earphones with no issues.
3. CloudyG3 2.4,2.5:
ROM is smooth, but getting hot instantly when I start gaming.
Getting only 2.5hrs SOT if I play Clash of Clans.
4. Stock Lollipop:
I feel the heater here. :silly:
5. Stock Kitkat:
Heat is bearable, but its not stable, laggy.
Please suggest me the ROM and KERNEL and MODS which will not make that hot.
I play Clash Of Clans and need good camera.
Please suggest me.. Im depressed
But... 3.5hours SOT is normal for some if you use 90-100% brightness... Clash of Clans 2.5hr SOT time is okay, as it is demanding online game.
Thermal mod will only break your phone, as the throttling is there for a reason (heat, duh)
I do not see the problem.

I'm using mostly in 35% brightness.
My problem is its getting hot withing 5 minutes of browsing and within 5 mins of call.
I'm not able to play Clash of clans at all, Once I start playing it, I'm feeling like i'm doing CAMP FIRE.
I heard changing governor in kernel Auditur and some thermal settings will solve the heat issue.
And whether changing the Screen resolution is suggestible?

Demanding games make your phone warm. 2G and 3G calling doesn't cause heat.
4G high usage can make this phone hot. Only way to not get your phone warm is by underclocking it, but then games will lag even more. Screen resolution changing may pump the performance, but I don't know how much heat it causes.
This phone has never felt as hot as HTC One, which emit the heat through whole phone due its all metal casing.
I'd advice you to not touch thermal throttling.

I don't have a g3 but I have had issues with the phone getting hot in the past. I suggest trying different kernels to see if it resolves the issue. I currently use an S5 and use Ktoonz Kernel. He has an app called Ktweaker. In this app you are able to change your kernels profiles and scripts. Anytime I experience heat waves I change the profile to fix it. Use a different kernel and see what happens.

after flashing the ROM,
even before I complete the setup (1st boot after flashing new ROM), my phone temp goes to 74 C. Is it normal?
My phone getting hot even without playing games, not all the time though.
Thanks I ll try underclocking.
try cm12.1 with 777jon r10 kernel, -40 uv (you can try -50 or more if you want) and the thermal files from stock "/system/etc/thermal-engine-8974.conf" (that's the most important)
