[Q] Nexus 4 heat problem

I am getting bothered by the heat of my nexus 4 especially at the camera side..., when I play psx emulator it really gets hot and it gets hotter when it is charging... even if i am only watching or streaming the internet it gets noticeably hot, so i would like to know if this is ok or not.
what are apps that could monitor the temperature?
what is the normal temperature when gaming and idle?
I would like to know about this things so that if my unit is a lemon, i could return it to lg for the warranty.
thanks in advance.

you have a quad core device, its normal. when you stress the cpu, gaming, streaming, itll heat up. when you charge, your battery will heat up. the back o the phone is glass, so itll feel like it gets hot fast. when the device hits a certain cpu temperature, heat throttling kicks in. this will lower your cpu speed and cool down your device. when it goes over the cpu safety temperature(100C i believe), the cpu will shut down and the phone will power off. there are several apps that show the cpu and battery temperature. remember, battery temperature and cpu temperature are two completely different temperature readings.

System tuner gives you cpu temp. But you should get an app that tells you battery temp as well...

ok thanks..., I'll monitor my device and post the temperature later.
Idle

simms22 is right you can under clock it safely kernel tuner is free on play

Intel CPUs (i5, i7, etc.) can survive going over 100 degree Celsius, but the commonly quoted safe temperature limit for long term operation is 70 degree Celsius. I would assume that the same holds true for other silicon chips, and find it difficult to believe that the shut off temperature for the Nexus 4 is 100 degree Celsius - you will be getting serious burns on your fingers by then.

Wait..., I recently played a 3d game and my temperature is reaching
CPU: 67c
Battery: 50c
Is my phone a lemon or its a normal case scenario?

Hi all,
For "hardcore user" there is a thread with a solution to limit the heating :

Is this temperature normal??

That is a little worrying. Are you using a case? Also what is the room temperature where you were using the phone?

sorry for the late reply I thought no ones going to reply with my post, the room temperature is 31c. and I dont use a case

[Q] Phone overheats while gaming

Hi,
I've been using G2 for the past one week. Within minutes of playing a game( `10 mins), the phone heats up a lot at the back where the camera is placed.
I dont even need to play high end games like NOVA 3. Just regular games like Candy crush, Cut the rope etc heats up my phone real bad.
It heats up so much that its impossible to touch it with your hand.
Please advice if anyone has faced this issue.
Regards
Georgi

Same with me, but only plants vs zombies 2 may be its just one game.

Please don't post same question in more than one thread. Your question belongs in the question and answer section where you have it now also. Not here please.

Same here. Maximum overheating is seen during plants and zombie 2.

Hi,
Guys you realize that you have a quadcore at 2.26 Ghz... And when you play a (heavy) game or some other heavy tasks (browsing in 4G for example) it's normal that the CPU heats, right?
Temperature is very subjective without reading the CPU temp with an app, it feels hot in your hand (you can have cold hands and in this case you feel much more the heat) and it's hot because the CPU temp is about 90°C is different...
Heat and overheat (or "maximum overheating" like above ) is different too..., in any case there is a thermal throttling that prevent overheating. Our CPU shutdowns at 120°C so there is a little room... Even 80°C is nothing for the CPU...
Even 90°C for the CPU temperature is almost nothing (for the the stressed people) and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
And if you speak about "overheating" when playing a game or browsing while charging your phone...
Check your CPU temp with an app and report here...
It remembers me all the threads about "overheating" in the Nexus 4 forum...

I will definitely try installing a temperature app and will report the temp soon.
I'm worried that the heating takes place near the area where the camera is located. Can this have any adverse effect on the camera?

I cant vouch for a smartphone camera in general, but I know I had a newer regular old camera that sat in the sun and the heat for a day, and was perfectly fine. I don't see the heat damaging the camera.

[Q] Mahdi ROM: Temperature during intensive tasks!

Hi.
Question for Mahdi ROM users on the LG G2:
Coming from this thread, I'd like to know how Mahdi ROM's temperature is when you do intensive tasks, like playing games, running benchmarks etc. Does the device get hot? If possible, tell the temperature, what you were running, for how long, did the screen remain on etc.
Thanks.

Anytime you run an intensive game or the like your phone will get warm, no matter what phone it is. Benchmarks get warm too, however I find those to be useless.

It isnt useless, he's collecting informations about the black lines from a few roms...at least be happy that we have such guy on our G2 section, who is willing to help out as much as he can..

Hot as in "it shouldn't be at this temperature at all while doing what it's doing".
So that means 39°C tops. That's a bit above human normal body temperature. Not bad.
If I remember well, playing Plants vs Zombies 2 gave me 47°C tops in GSAM Battery Monitor, without ever rebooting.
Thanks.
Compass.

yeah max I had was 50°C, but not very long.
I guess it can shoot up higher, but for usually when doing intensive stuff, its about 39. Not to bad.
was one build it was 42 also in rest. That wasn't to long though. pretty cool, new build and fixed haha

@Compass Linux - my device gets extremely hot on any aosp rom even on normal usage, like web browsing, texting, checking emails and reading certain articles on the web, the cpu temp ranges from 50*C-60*C at times even 70*C and it gets throttled down as i set my tmep trottle at 70*C.
battery temps range between 27*C to 43*C which is NOT normal so im no longer on any aosp roms. it scares me as for lithium batteries temps above 35*C is bad for its life. also none of these temps are good for the phone so now im on pardus hd 7.1 and my cpu temps are within the rage of 35-50*C and battery temps from 32-35 under the tasks which i mentioned earlier.

cpu will happily run ~75c without throttling, max temp is 92C at which point it will turn off.

If it was bad for the CPU why would it come from the factory to start throttling at 75?
I think you're mixing your views of desktop CPUs on to SOCs.
SOC (system on a chip) are crested to be passively cooled.
For this phone 30~50 idle/light tasks and unto 75c underload is perfectly normal and safe.

G3 Temperature Throttling

Stuck my phone in the freezer for a few minutes, took it out, and ran the stability test in AnTuTu which plots the temperature and a benchmark score. Looks like it starts right around 34 degrees (93 Fahrenheit), which really isn't that warm at all. You could get that just browsing around and holding it in your hand.

My cpu temp is normally in the 40's and 50's while browsing.

Have you tried turning the thermal daemon mitigation and high temperature property off in the hidden menu and see if this throttling happen? Will be interesting to know if the hidden menu selection works.

It does work. you can just open an app like setcpu and you'll see that it rarely peaks without disabling throttling. Just be careful as it does open you up to potential hardware failures and shorter life of the device. I only keep phones for around 6 months so I don't care but I'm not a normal usage case.

Wouldn't the hardware still have a thermal cut off point where it will just shut down the phone if it gets too hot? It's to my understanding that this hardware shut off point is different than the software thermal throttling. If anything, I think it will just make your device get too hot for comfort than do any real hardware damage to it.
I'm just throwing an educated guess out there though, I honestly have no real proof one way or the other.

Yes eventually it'll hit tjunction and shut down. This isn't even a safe shut down though. It is basically an emergency kill switch. It's like yanking the cord out of the wall on a desktop. Running at higher temps also shortens the life of the silicone. Much the same effect that overclocking has on a normal PC.

If it gets hot, it will do damage. It can fry the GPU before it even gets to shutdown point. The XBOX 360 for example had the RROD where the constant heat made the solder joints fail (I know the 360 is different but the heat point stands)

The 34 in this case is temp or battery, not SoC. The SoC is probably hit 75 Celcius and that's why CPU throttles. Try HWBot bench instead, it shows not battery but CPU temp. You will see that CPU immediately hits 75°

Afaik they shut down itself if battery hits 60°C or CPU burns to smthn like 105C

HWBot runs parallel... If you want to see your CPU get really hot press the button multiple times. Phone melted!

Why does the snapdragon get so hot. I don't understand what's the point of a fast chip in these phones if they can't run on there maximum lol.... Maybe that's why Intel is gonna take over qualcom one day.

It runs hotter because its having to produce all the pixels for the QHD. The same chip in other 1080 phones doesn't run as hot. At times doing normal things like browsing and Facebook etc my phone has throttled down to 1.4Ghz max and the CPU temp is up at 65-70deg C. That's pretty hot.

Its not the only phone. And mine never throttles that low doing normal tasks. It doesn't even throttle at all. However, when playing games or running demanding apps it does throttle.
Also, its not the only phone that runs this hot. All other phones will get hot and throttle just as much when running equally demanding stuff.
So the question was, what's the point of super fast chips when they are going to throttle themselves so fast?

I'd recommend that you do a bit of testing,run some apps for 5-10 min then open up a CPU frequency app. The frequency will be be at a low maximum and the temp high. The GPU also throttles, open an app like Faux clock after running some apps and the max GPU value has decreased. Without a doubt the extra pixels are causing this as the SOC is having to work harder to produce them. Its simple physics.B
But anyway, its a specs game. People want faster and better so that's why the SOCs get faster and faster even if they're throttling.

The soc is working harder, but like I just said the how soc is still hot even on other phones man.
Run the dead trigger on the s5 and the g3. They both most likely throttle down to the same limit while the fps on the G3 might be a little lower due to the resolution.
But like I just said, what's the point when the damn thing will burn. There is no point in 2.5ghz when your phone can't run at that frequency more than 5 seconds lol.
I remember when I used to run my Galaxy S One full speed. Not one but of throttling. These CPUs have not gotten any more efficient thermal wise.

Yeah, I agree there's not much point in having a super fast chip when it throttles so much. Again, people want bigger faster and better and most users wont even know about thermal throtlling.It does seem to be bad on the G3 though. I think I saw another thread that said LG don't use a proper thermal pad also. Don't know about that but to run a 1080 phone with the same chip as a 2k phone then you'll have thermal and performance issues on the 2k Vs the 1080.

The 801 is more than capable of driving a QHD phone. The 800 series are basically created to support up to 4k. And how will give the same performance as a 800 while on QHD. Its not even close to being a big deal. And yeah I saw that same thread. I wonder if it's true.

I see that the layered CPU/memory unit has a metal cover to it, im wondering if a thin thermal pad could be placed between them to conduct heat to the metal cover. Its not much of a heatsink, but it might help a little bit. It may even be possible to put a thin copper sheet on the metal cover to move heat away. It all depends how much room there is under the plastic cover. The only teardown ive seen doesnt make it very clear.

What is the normal CPU temperature ?

With normal tasks such as browser, phone and messaging, the CPU temp of my phone is around 38-40. With tasks as YouTube and graphics intense games it's between 50-55. At this point, the phone feels really hot.
Are these expected temp level or is there some problem with my phone?

With asphalt, the temp averaged around 65C. While downloading the additional content it reached 75C.

I rarely see mine above 45. I've only seen 50 a few times. Throttling kicks in bad above 50

How can i check the temp of the CPU? Most of the apps don't even show temperature on 6P and CPU Z gives me like 15 different readings ;/

For this I had used CPU Temp. But yeah after the update, it says that it cannot determine the temperature.
In CPU Z, I was unable to understand the readings. One of the app, said that there is no temperature sensor to determine the reading of the phone. So not sure if we can get the accurate temperature.
But the phone is for sure getting too hot. I feel Nexus 6p has heating issue, or atleast mine does.

45-60 shouldn't damage your CPU, but 75+ can be harming for phone's integrated circuit

Remember that it will go up to 70°C maybe higher and the aluminium case spreads the heat making the whole device hot (LG G3 was very hot only in specific area, because it was plastic).
