Heat - Nexus 4 Q&A, Help & Troubleshooting

Hey everybody I have the "problem"that my n4 heats up very quickly on 3g until 50-60°celsius. Is this normal ?

It must be because you are using apps or games that like high frequencies
Either undervolt or spend less time using your phone

What to you mean heat up? the temperature of the battery or you have a thermometer on the phone? and do not take the temperature while the phone is charging. it supposed to go up!!!
mine battery temp is about 25 degrees with a max of 30-32. ambient room temp is around 20 degrees and the phone is not in direct sunlight. note that my cpu is undervolted (150mv down) and underclocked (at 1350mhz) but playing games the temp doesn't go more than 32.
in some forums i have read that it is normal the back of the phone to heat up because it is plastic and plastic does not spread heat like aluminum.
hope i shed some light...
ps. the degrees are in celcius

thx for ur answer but im talking about the cpu temperature not about the battery temperature. for battery temperature i hav the same values like you. my cpu is also undervolted until nearly -200mv^^. but anyway thx.

how can you see the cpu temp?? the nexus4 as far as i know has not any sensors for the cpu temp

after about 5 mins of gaming (riptide gp2 that has quite heavy graphics) with wifi and 3g on the temp of my cpy via trickstermod is about 42-43 degrees when i immediately leave the game. if you need me to check anything else feel free to ask.

with brightness set to 100% i hit 49 degrees afte 5 mins gaming with wifi and 3g enabled. that is normal (i think) if you consider that the thermal throttling kicks in at 70 degrees (checked it in franco kernel updater)
edit: before the brightness was set to auto so i think it was about 15-20%

It's normal to get around 50 degrees on 3G or more during gaming.

This. My CPU temps have often hit 80C when playing graphics intensive games. So don't worry about it and enjoy your phone!

Isn't that a bit high? Isn't the CPU clocked down when reaching 70 degrees?
I have experienced that sometimes... Then even a quad core becomes very slow

I have thermal throttling set to 85C. So no downclock until that temperature is reached.

N4 and gaming temperatutes

Hi all I have spent same time in last days playing Real Racing 3. Very nice game.
While playing the temperature of my N4 became very high. It's a 1.5 quadcore with GPU working hard so it should be normal. But I saw, in system tuner, that while gaming it can reach even 70 Celsius. Is it normal this temperature in gaming or should I be worried?
What about your temperature in gaming?
PS: for the battery this game can drain all the battery in less than 2 hours, but even this should be normal because without gaming it usually reach 4 hours screen on, so 2 hours of hard gaming should be normal.
Let me know.

mine gets 49celcius after 20mins of NFS MW Used to get 58celcius after 1 hours. But sometimes I feel it's normal after 20min of NFS, maybe it depends on the stage I am playing

Damn compared to your temperature mine are extremely high. What rom and kernel do you use? And what is your CPU bin? I have cyanogenmod M2, stock cyano kernel and fast CPU.

I think your temp is normal.
I use stock rom, franco kernel, UV 150, fast CPU bin.
R: N4 and gaming temperatutes
Ok maybe common but IMO this temperatures are pretty high. I just hope to not damage my device to play sometime. Heat is the worst enemy of electronic components.
And for this I like UV a bit but I don't know if CyanogenMod kernel makes different voltages according to different CPU binning.
I hope so.

What are the safe operating temps? I tried real racing 3 as the first game I tired on the N4 and as soon as it heated up I uninstalled it in fear of burning my device up.

phew! good to know that I'm not the only one with this heat up problem but I guess its not a problem
Got my n4 just yesterday and immediately started downloading Hd intense games
and because of all the playing I have to charge my phone twice a day now...
ive seen 100C cpu temp on my device, then again i was trying to reach it. i wouldnt worrry too much about the heat. if your device gets warm enough then the heat throttle will automatically kick in. itll reduce your cpu speed and cool down the device. if you keep pushing your device past the thermal throttle, itll eventually hit the automatic thermal safety shutdown temp, which will automatically turn off your device to cool it down.
R: N4 and gaming temperatutes
Good to know that I'm not the only one with this temperatures... In first moment I thought of down clocking GPU and CPU... But damn it's not possible to have a mobile with quad core and powerful GPU that can't handle the heat. So I hope they managed it well and get used to a burning phone while gaming.

Generally, you should not let your phone temperature get greater than 50°C. Otherwise, you risk permanently heat-damaging the battery.

100C is the safety shutdown temp for the nexus 4, your phone wont melt at that temp. my gnex has hit 110C many many times, thats the shut down temp for the gnex.
you have to realize that there are two different temp readings, cpu temp and battery temp. while your battery reaching 50C isnt safe, 50C for the cpu is still relatively cool, and does not put your phone into danger.

"ive seen 100C cpu temp on my device" This is what sims22 says. I have no idea why you would think "100C cpu temp" is "100C battery."

cpu tempature 91°C

So am running classic stability test 2.7, and I've ran this before and my CPU get to 60°C or after like 15 minutes, I ran it today out of sheer curiosity and it started to show 91°C. Am using cm with there kernel since I recently flashed the latest nightly and thought how would it differ from matrixes. Another thing it can be that the values are being incorrectly displayed. Is this something I should worry about? Am really not in the mood for an RMA and losing my phone. Shouldnt of the system shut itself down after a certain limit as a fail safe?

Are you sure it is Celsius and not Fahrenheit? Is about 33 degrees Celsius. At 91 degrees it would have shut down and rebooted a long time before reaching that temperature.
Trickster mod says its °C so?
edit: the device itself gets very very hot which am sure if it was running at 30 it would be fairly cool would it not?

- touch the back, if it's 91C your fingers will know.
- RMA because you run a heavy benchmark test (I never do, no opinion on that) and it -logically- heated up..?

it was very hot I had to put it down so am guessing its 90C, but now its a lot better, it seems it wasn't throttling proper? it attempted to run the entire thing at 1.5ghz constantly, rather than it's usually clocking down to 1.1ghz. Now it's throttling and while its at 78C, it just feels warm and it actually being managed.
I flashed back to matrix's kernel and prefed to use the scaling test which would probably be closer to real life usage and its running 45C. I really like CM and don't want to flash back to stock but I may end up doing it
Note to self
Don't run stability tests

90c will probobly burn your skin.
it was mistake.
Must be a mistake. 91 degrees Celsius is almost 200 Degrees Fahrenheit, that would melt the plastic on the phone, and burn your fingers.

not true. ive forced mine to hit 100C. its the cpu temp, not the temp of the outside of your phone. ive even hit 110C with my galaxy nexus. it doesnt stay at those temps long enough to melt your phone, lol.

stability tests are meant to push your cpu to its limits. pushing the cpu to its limits will create lots of heat. it is meant to do that. if youre using stability tests, you can not complain about heat. its like putting your car in neutral then flooring the gas pedal, itll cause your engine to get hot, especially if you do it for 15 minutes.

safety cpu shutdown for the gnex is 110C. as soon as i saw it hit 110C, it shut down. but you really have to try to get it to that point by stressing it awfully hard. same with the nexus 4, 100C is the safety shutdown. running certain benchmarks or stress tests are the only ways to get it that hot. which is why it makes no sense that someone running a stress test for 15 minutes is complaining about heat, asking if he should rma his device.

I think you are referring to battery temp and not CPU temp. Unless you live somewhere very cold it would be quite difficult for your CPU not to go over 40c

Canada its fkin freezing!! just checked set cpu and its 23 c, but im just scrolling through twitter, not really doing anything else.
The points that I would be concerned with temps are
Battery > 50°C
CPU > 80°C
This is based on stock thermal throttle at 60°C CPU
On Franco kernel I have upped my throttle limit to 70°C so I wouldn't be concerned unless it went above 85.
You will know if your battery is at a dangerous temperature because it will be very uncomfortable to hold
I just played some beach buggy blitz for 10 mins.
CPU jumped up 20° from idle up to 50° but again well within my tolerance

for the record am not asking if I can RMA, am happy with my device and really don't need to lose it for a week. But this just started happening more frequently. Sometimes the thermald ****s up and it doesn't throttle at all, at times I could be just playing GTA, Worms, Plague etc I usually don't notice because the phones down on the table, pick it up and owwwww flashing back to matrix solved the majority of it tbh. Right now it's sitting on 31C idle, it'll be about 40-50C on chrome funnily enough, and then 60ishC on games, pushing 70 depending how long I leave it on. I see that as fairly normal tbh, but 90C? I wouldn't even trust my fan cooled i5 to go there.
And am back were I started just playing 2 minutes of batman and its at 70°C and burning my hand
wow 91° ?? its dangerous maybe your device will " BOOM" sometimes :0

cool.
but yea, its possible to reach those high temps if, and only if, pushing your cpu. itll get warmer faster if your gpu is overclocked(is gpu overclocked in franco kernel?). now, if doing nothing and the phone gets that hot, thats a problem(software or hardware).
nah its not overclocked, atm its cooled down, although it does take a while to drop from a high temp to something low even on idle.

Nexus 4 Heating?

Hello, I've had my nexus 4 for about a week and a halfish now and I've noticed that the phone is running pretty warm after even just light usage. I download a battery temperature reader and a CPU temperature measurer. At Idle the batter temperature is at about 33-36 degrees Celsuis. And the CPU temperature at Idle is usually in the lower 40's at idle. Are these Temperatures to high?
Also When I plays games or use any apps for a just a few minutes the battery Temperatures get at around 40 degress C and the CPU temp is usually around the 45-50 area. Again Are these temperature to high?
I would really appreciate if anyone could give me useful help on this issue I'm having with my phone.

I'm assuming your Nexus 4 is a newer one (rev. 11). Nexus 4s have been known to run quite hot. My rev. 10 is at 42 C coming out of sleep without use, earlier when I played Need for Speed, it got to 60 C. It seems to be normal for mine, although it does get uncomfortably hot.

completely normal. right smack in the middle of the range of normal. remember, human body temperature average is 37C or 98.6F. when you use your device, the temp will go up when you use a cpu intensive game, the temperature will get even hotter. this all also depends on the surrounding air temperature. the warmer it is around, the warmer the device will get or idle.
Normal. Because the back is made of glass, it absorbs the heat and you feel it more than other phones.

Hmm, That seems weird, if the phone throttles you at 37 degrees shouldn't my phone not be idling at that temperature, and the my front screen seems to get warm after slight usage to. And looking on other forums people with a stock nexus 4 said that there phone idles around mid twenties, not the lower-mid thirties.

for hard working with QuadCore it s normal to get ~40 C quickly
But after 40C i think it s not normal and it s better to ask official service

look at the time they were posted. now its warmer eveeywhere. and again, human body temp is 37C. you have a quad core phone, it WILL get hot at times, that is normal. pushing the device, you might even see 70C or 75C.

Hmm okay I have pushed the phone and the highest CPU temp I reached was about 60ish. I'm not exactly worried about how hot it gets, it's just how fast it gets hot, it seems a little odd that just running facebook and twitter for a few minutes can get the battery temperature up to 40 degrees celsius.

That sounds similar to the results that I have found on the web, people said that to get there battery temperature up to 40 degress they have to push the phone, mine gets there just by opening a few apps.
If you want to cool it down and you are happy with messing about with your phone, try undervolting the CPU. Although I tend not to check the temperature, my phone (UVd by around -150) feels far cooler; playing Real Racing it doesn't get as warm as simple browsing would on stock.

40C is not hot. get that out of your head. idle temp will depend on the air temperature around you. yesterday was 91 in nyc, my phone was idling between 39-42C. stick your hand in 40C water, itll barely feel warm.

On a surface like metal it would, but not in water. That said, the back of the phone isn't water but I'm sure the temperature of the back of the phone is lower than the CPU

Couldn't agree more, The back of the phone I wouldn't say it HOT, but it is definitely very warm. But I'm not talking about how hot the phone feels. I'm trying to ask about the internal temperatures and if it's normal for it to heat up so fast.

again. this is normal. 104F would not feel more than slightly warm water.
the glass in the back of the phone is there to draw out the heat from the phone. its glass, and will feel warm. if you have problems with 40C, then i would recommend that you buy a dumb phone. my nexus 7, galaxy nexus, and nexus 4 all idle a bit warmer now than in winter. 40C is very normal.

40C is not hot. get that out of your head. idle temp will depend on the air temperature around you. yesterday was 91 in nyc, my phone was idling between 39-42C. stick your hand in 40C water, itll barely feel warm.

Its normal, have a look at the graph!

[Q] G2 Operating Temperature

Hello guys, well i've read every single post about the phone's working temperature on the forum but i just can't figure if my phone is working fine or not, because mostly everyone on the post refer to the temperature as "warm" "bit hot" etc, which is very subjective. I'm a bit worried because my phone (D806, running stock ROM) gets quite warm after like 20 mins of surfing the web through wifi, or after chatting a bit on whatsapp. By "a bit warm" i mean between 32-34 deg centigrade, refering to battery temperature of course. Now, after reading everything i can't figure out if this is a normal temp for this phone or not. I can also say that the min temperature i could measure (with just cell radio on, in idle state) was 25 degrees. The max temperature i could reach (running antutu for like 4 times one after another) was 45 degrees. Now, i'm confused because someone in a post said the max temperature he got was 34 degress, and his usual temp was 24 degrees. I couldn't even get 24 with the phone completely idle. So, i'd like to know your experience, since i can still exchange my phone for a new one if it's defective. Thanks in advance.
Hi,
There is nothing wrong with your battery temp. You can also check you CPU temp (nope, maybe you will have scared )... Fortunately you didn't saw your CPU temp during your 4 Antutu runs...
The temperature (CPU or battery) depends of your room temperature and your current use. You said yourself with 4 Antutu runs the temperature increase, nothing abnormal even for the battery..., same thing after browsing for 20 minutes even in wifi.
A guy had 24°C battery temp in idle and 34°C max, well, what was the room temperature? Nothing running in background? What he was doing?
I mean even in idle, screen off, your phone can do a lot of things especially if you have a rogue app keeping the CPU busy so there could be a little more heat.
In any case there is a thermal protection (thermal throttling) to prevent damages in case of "overheating" for both CPU and battery the CPU freq decrease according to the temp. Even the screen brightness can be automatically lowered. In last case the phone shutdown if a high temperature is reached (about 100 °C for the CPU). The max battery temp should be about 50°C, I don't remember exactly.
Don't worry, as you reported there is nothing wrong with your tempetatures... Same thing if you take a look at your CPU temp, can be arround 70°C in heavy use, even a bit more in really heavy use.
We have a quadcore device running at 2.26 Ghz, all is enclosed without thermal cooling... it's normal to have "heat" with all the components.
Use your phone and profit, no need to monitoring each minutes your temperatures. You confused yourself by only reading the °C, not how or why it is compared to the other posts you read. Each user have different room temperature, use, settings, etc... you can't have the same temperature as xx user. An average yes, I agree and here you are in the good average...

Viking said it all. Nothing abnormal there, but anything over 30 degrees is elevated temperature and should be avoided

Guys,thanks for your responses. I still don't get something tho because one of you said that my temp is normal (about 32 deg. while browsing), but then you say that anything over 30 deg should be avoided, then i don't quite understand. My phone gets between 30 and 35 deg while regular browsing, it's mostly a bit over 30 all the time i'm actually using it, SO, that's wrong or not? That's the part i don't quite understand.
I guess vPro97 made a typo or he was sarcastic?
Over 30°C for the battery temp is not dangerous at all, about 45°C also. Imagine people living in a really warm country when they use their phones...
Don't worry, already said, there is absolutely nothing abnormal with your temperatures, nothing... all is fine regarding your use...
Don't panic

Right, thanks a lot again guys!:good:
just make a grilled cheese or scrambled eggs on it. Let it vibrate while cooking for extra pasazz
the slick back then not that bad right

High temp always, shutting down big cores

Since 3 days am getting high temperature on my phone and also because of that lower cores are being shut down all the time. Temp doesn't go Below 40 degrees. Can anyone help. Stock with elementalx.

Is the phone body emitting heat?
That's really odd, did you over clock anything? I've never had that issue on my 6P even running a 200mhz OC. Does it happen at any particular time?

Nope. No OC. It's hot here in india. But i guess that's not the reason. Game's are lagging. Temp minimum is 39 goes upto 59.

That's still strange, I'm from Arizona here in the US (gets to over 49°C during the summer sometimes ) but since I'm in a cooler part of the country now I can't check to see if the outside temperature is the culprit. Do you have a case on it that holds the heat in rather than dissipating it?

Could I just ask you how did you manage to measure the CPU temperature? I was looking for a way to do it but it's either ROOT or CPU-Z which doesn't show temp in the background.
