Relatively high temperature of CPU - Nexus 4 Q&A, Help & Troubleshooting

I'm using Air kernel with sentinel ROM.
For some reason, CPU temp is always 40° C+
I tried undervolting (currently it is 1000 MV @ 1512 MHz)
CPU range - 286-1512, intellidemand
What's wrong?

If you talk about CPU temperature its normal but if you talk about battery temperature then its not normal.

Battery temperature is 37°C
My friend @eRajesh says CPU temperature is 30 for him

Your phone is probably in your pocket. The average temperature of your body is ~38°C .
40 °C is not a high temperature for your cpu, especially if you're using your phone.

40C is completely normal, especially while in use. what is the air temperature around you?

Yep that's normal. As long as it doesn't reach 60c with light usage you're okay.

More than normal ^^

[Q] Battery temperature levels

What would be the temperature of the phone when overheating?
Sometimes it feels like the temperature is very high but I don't know if it's overheating or not. The maximum I had was 36.0°C/96.8°F.
how can you tell? the phone temp keeps staying at 0C...

Galaxy s3 hot problem and soloution (experimental)

Hi guys I am from India and on international s3 and face a problem that s3 get hot upto 48c
I have a solution for this(must be work)
1. First of all disabled bundled stock apps like chat on etc I have attached a screen shot of disabled apps on my s3
2. Off NFC android beam.
3.disable s voice( big battery eater)
4.must disable s memo and exchange mail
5.clear cache of all files and apps weekly
6.flip board users plz clear your cache routinely( this apps has a network bug that eat more battery in less time.
7. Set sync of apps like Google +,mail,wheather to 6 hours.
Screenshots are below.
Plz tell me after disabled these apps attached below that the tricks work or not

48°C is really like nothing. I remember SGS 1 & SGS 2 especially were getting almost 60°C.
So - unless some expert denies - I'm pretty sure temperatures up to 70 will not make harm.
With one exception: temperatures above 40° will shorten battery lifespan in the long run. Li-ion batteries don't like this.
Sent from my Galaxy SIII
That sounds crazy, 70°Celsius? How can you actually still hold the phone on that temp? Almost impossible. My S3 never reached 40° Celsius once so far. But i remeber my HC Desire, when it was very hot outside, it reched almost 50° Celsius and it was HOT like **** in the hand i couldnt hold it very long tbh. And i dont think that this is good for the phone.
70°c can damaged your s3 CPU and you cannot hold the phone. So plz don't make such a comments on temp.

My device is at 40 degree at normal use
I have read (will post the link if I can find it again) that if a battery gets to 140°F then it can go into a self heating mode, not allowing it too cool down, and eventually catch fire. However, I have accidentally left my dx charging in my car on a hot day and when I came back out, it had shut down and had a "battery too hot" notification. That phone would power off if it got too hot.

My gnex once hit 110c CPU temp and it still works fine, it was regularly hitting 80-90c during benchmarks.
To say that 70c will damage a CPU is absolute nonsense, a quad core CPU running at 1.4ghz will hit 65-70c no problem under full load before temperature throttle kicks in and limits the frequency to cool it off.
Battery temp is a different story, 70c battery temp will probably end up damaging your phone/battery.

Do you really mean Celsius? Water boils at 100°C and I don't think that a CPU could even stand such heat..

Yes I do mean Celsius, and a CPU isn't made of water...
It shut off as that is the safety cut off point for that particular CPU.
I had temperature throttle turned off.
Quite a few people have hit that temperature, go to the gnex forums and ask Simms22 if you want further proof.
I KNOW a CPU can handle that heat because I have actually seen it.

Hi,
I agree with nodstuff and I can confirm
The same thing with my Gnex (not with the same kernel ) With a modified CPU temp limit my Gnex is going up to 98°C, never try with the CPU temp limit disabled but indeed it shut down at 110°C, it's a fact and it's in some doc of TI.
And about the temp of the SIII here we talk about the temp of the battery, not the CPU temp, this is not the same thing, although there is some correlation (but actually with, for example, a battery temp of 50°C, we don't know the real and actually CPU temp)..
When will you have an CPU temp in the SIII??? There is a CPU temp sensor but If I'm not wrong for an application to read the temp the kernel must support it (it's hardcoded).And as far as I know actually there is no way of knowing the CPU temp.
At first with the Gnex it was the same thing, no CPU temp and Franciscofranco has enabled it (the reading by an app) in his app (and also with anothe 3rd apps after) so we can see the CPU temp in real time.
I really missed this feature with the SIII...
May b it can handle so much of heat ..but the question is about using the device whn its hot..do u think its will b very convenient to use the device whn the device is at 100 degree?
I guess its not possible !

Its not just the cpu.. when the heat is dissipated the whole area including the screen gets hot.

Hi,
Hot for sure but obviously not the same temperature of the CPU.
Temperature dissipated, yes, but not 100% transmitted at all the phone. CPU at 110°C you can imagine that the screen is not at this temperature for example, like the back cover, otherwise beware of burns and it's not the case.
When my Gnex reached 98°C it was hot but not unable to hold in hand.
Guys, you never used a Gnex (or another phone maybe) without a CPU temp limit, so disabled, or a modified CPU temp limit with an higher limit before thermal throttling...? The phone is still usuable.when I read you speak about very hot, extremely hot, or overheating with a battery temp of 45°C... Should not you know the CPU temp...
Ok the battery temp could be useful but not as much as the CPU temp...

Nodstuff why you not understand the temperature theory for CPU or mobiles if your CPU take in 110°c temp it can caused many problem and reduce deficiency of your CPU.
Other people are saying all this thing so plz listen carefully and don't run your phone on 110°c

[Q] horrible battery life?

77% in 49 min and screen on for 49 min. Is this bad battery life? What would make it better? Thanks guys. I'm on cm10.1 with Franco. Clocked at 1026 min and 1512 max.
sounds average. Doesn't sound bad. Bad would be 49 mins screen on and you're at 50%. Screen brightness all the way down? Or is this cranked to the max?

All the way down. Good to hear that's it's not too bad though
Wait, could you tell us your governor? Franco kernel uses interactive as a default which in that case, you don't need to put the minimum to that high
49 minutes unplugged and 49 minutes screen on on 77% isn't that good at all. You should get at least 1 hour-1.5 if you were using it constantly.
Sent from my Nexus 4 using xda app-developers app
That's not so good IMO, I attached some pictures of what I'm getting, I'm also on CM10.1 and Franco.
You should flash Franco's and let it be, don't put the lower value that high.
Autobrightness on, Sync on, wifi always on, but not always connected (I always forget turn it off )
Could you please check how many mA Battery Monitor Widget reports?
Mine only shows 1500mAh, even when the battery is fully charged.
Would be interesting to know if this is a faulty battery or just displayed wrong.
Maybe that's why some get pretty good battery life, and on some it's really ****ty.

Really depends on what you're doing in that 49 minutes. If you're playing games, have poor data connection, uploading to dropbox etc you can see the battery deplete really quickly. I never get great battery life because I use my phone a lot with the screen brightness all the way up.

Also use latest Franco. He fixed a lot of things on the latest test version and it is smooth enough to use it in daily basis.
Also could you tell us what you were doing in that 49 minutes? Games take so much battery out thanks to beefy 1.5 GHz quad core processor. Thanks

You must be looking at the battery temperature.
Use system tuner or something to check the actual CPU temp.
If it's hot when phone is supposed to be idling or doing simple tasks you must have a run away app or something causing it.
Also check you haven't left the governor set to performance or anything like that.

[Q] Nexus 7 getting too hot

Hey
I bought my nexus 7 about three days ago and I think I have an issue.
When browsing the internet or watching a movies my nexus can reach 35c and when playing tegra 3/Gameloft games it reaches 39-40c is it normal? Happens to all?
It's little annoying and I can't enjoy these games....
Any ways to solve this problem?
What are you talking about, thats waay to low, my OC-ed nexus 7 can reach upto 70c and about 69c should be the top limit, 50c is usual temp, or atleast it should be when browsing

What the hell? 70 celsius ? you can cook with your NEXUS 7 LOL
How you deal with it?
well you know, undervolt for about -100mv, which is pretty stable, if necessary lower my oc to 1.5 ghz and it never crosses 63-64
sorry if i offend you with this question, but is it possible that you were looking at your battery temp, not cpu?
because usually those temps are from the battery, it seems just too low for almost a high end device (atleast it was)

Yes I mean battery temp
minecraft
I have had the same issues with the heat on my device. I notice it gets pretty warm quick right where the rear camera is and also the glass gets pretty hot too. I been playing minecraft and it heats up quick, I checked the battery temp with an app and it reached to 31C. This was from playing for about 15 minutes. Browsing the net or watching youtube doesn't have much effect but watching a video with the browser did make the device pretty warm. I gotta admit when playing games its pretty uncomfortable.
Even 40c isn't that hot for an electronic device. I remember my old Galaxy S 4G used to get a battery temperature of 52+ while charging and playing guns n glory in a non air conditioned guard house. Every so often I'd stick it in our mini fridge for a few mins to cool it down.
I would've loved to see how hot that poor processor got, but battery temp was the only one you could check on that device.
