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...

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?

Hi,i'm new here and sorry for my bad english
I'm on PA 3.1 and since PA's base upgraded from 4.2.1 to 4.2.2,my nexus 7's bottom left corner got warm and hot than normal,CPU temperature is usually at 36-37 °C,even when i just browsing/reading
I just want to know if anyone here got the same issue as i got
Thank you and sorry again for my bad grammar
I did the same jump as you from PA 4.2.1 to 4.2.2. I haven't had any heat issues at all. Mind you I have undervolted 50v across the board. It might be a rogue app.

what kernel do you use?
37-38 C is nowhere near to being high (if you are indeed talking about the processor Tj)
The stock kernel does a panic shutdown at 100 C, and rate throttles a little below that. (At the moment I can't remember if that happens at 95C or 90C).
That Tj temperature is measured by a circuit embedded in the face of the SoC chip itself, so it is literally the hottest place in the whole device.
I have run native multithreaded stress test codes simulaneously with OpenGL benchmarks, and while the lower left corner of the tablet gets warm, the maximum Tj I observed was about 85C (Stock kernel - no GPU or CPU OC'ing). When "idle" such as reading web pages, my stock device sits around 38C as well.
The only thing that is disconcerting about what you report is that you mention a warm tablet in conjunction with 38C. That shouldn't be the case unless you made the temperature measurement substantially later that the CPU/GPU load which created the temperature spike.
Remember that there is a substantial delay between a peak temperature felt through the case and when the CPU goes up to high temperature. In my experience, it takes several minutes of maxing out the processor(s) before you start to to notice that "lower left corner" hot spot. So if you are observing that behavior regularly, you do have a reason to be concerned.
good luck

Understood. I should have said "cat /sys/kernel/debug/tegra_thermal/temp_tj" to be clear.
60 C does seem a bit high for a N7 which is supposed to be doing very little work.
Mine (stock jdq39) is sitting here doing nothing but with the screen on (plugged into USB), not charging and it is about 42-43 C.
The effects of heat are cumulative - you should look into it.
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
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).
Hi there, so I recently received the Mi 9T I just bought a few weeks ago, and the first I noticed is that the phone is perfectly fine except for one thing: CPU Temperature. I set up the phone usually as how I set up my phones, and since I had a history of overheating phones, a good CPU Temp monitoring app is a must.
So I installed CPU/GPU Meter & Notification, but to my surprise, the CPU Temp is stuck at 37°C regardless of how hot or cold the phone is. (Even put it in a fridge for 15 minutes just to test it out). I also installed other CPU Monitoring apps but all have a static reading. However, using AIDA64 and CPU-Z has some readings on various temp sensors on the phone, though I'd note that the pm6150-tz displays a steady 37°C, which is most likely, the CPU Temp. Since the other readings there (~cpu specifically) update constantly, it rules out sensor problem.
I thought this might've been a problem with ROM, so I tried flashing Xiaomi.EU ROM, 12.0.3 Stable, and rooted with Magisk, but still, same problem. I went on googling about how to get temps and I came across thermal zone paths right on
(sys/devices/virtual/thermal_zone+zoneNumber/temp) in which had some crazy numbers (when viewed as text), one of them has 37000, 37100, etc. I don't know if this has a part in the problem or what, since this ticks something https://www.reddit.com/r/Mi9T/comments/cwqrqm/cpu_z_pm6150ibat_lv0_and_lv1_very_high_temperature/
I experimented with my phone even further and saw that CPU Monitor app View attachment 5053905 does have some CPU temps that do actually update (not just steady 37°C) when I charge the phone, or do some tasks. Though eventually, it's stuck again on that 42°C, which doesn't seem right at all since if I have 42 degrees, then I should feel the heat on my phone, but in reality, I don't even feel any heat at all, and the phone doesn't seem to be having a 42°C temp.
I ruled out bad heat dissipation as well by prying open the back of the phone and reapplying thermal paste (I used Arctic MX-4 btw). Yeah, forget about the warranty and such.
May I ask if everyone else has this problem? Maybe if you guys have some time to try out these two apps: CPU/GPU Meter & Notification, and CPU Monitor to check if your devices have the same problem or it's only isolated to just my phone.
I'd also like to know if this is not an isolated case, is it possible that there is a software problem? And can be ironed out by future updates?
Thank you!
UPDATE: It seems to have readings with CPU Monitor app (https://play.google.com/store/apps/details?id=com.glgjing.stark&hl=en) but they are quite inaccurate and puzzling. According to the app, when phone is at idle, CPU temperature are at 36-37 degrees, however, as soon as I plug the charger, the CPU temperature rise up to 40 degrees within 2 seconds, then when I unplug the charger abruptly, it goes back to 37 degrees instantly.
I let it charge for a while and did the same thing, only this time, the CPU temperature dropped to 38 degrees (from 41 degrees while the charger is connected), and the phone feels a bit warm, let's say it feels like 38 degrees for real, that's warmth is comparable to the heat of your neck when you have a mild fever
Go to aida64 and find a thermal zone you want to monitor, then find an app that gives you the ability to change the thermal zone to monitor.
I'm curious if changing thermal paste had any effect. Can you start a stress test and monitor cpu-0 and cpu-1 temps and see how soon it throttles?

I don't get it, how can I find an app that does exactly change the thermal zone to monitor, since I've already tried most of them, and they only go after the pm6150-tz sensor. Only CPU-Z and AIDA64 had readings from other sensors.
For the stress tests, I've been conducting tests on 3DMark, and it gets lower scores after the first OpenGL 3.1 Extreme Test completes. I can't switch over to AIDA64 to monitor temps tho, the phone simply lags a lot that I can't even see notifications properly until the stress tests are over.
I would like to try Antutu but I don't want to download it outside of the play store.
Changing thermal paste didnt have any effect for the temp readings. It only made the phone's frame heat a little faster, which I think means I put enough thermal paste that heat dissipation is good

Ok, I don't know of any apps that can do it that way properly. But anyway, I don't think you need to worry about temperatures. Especially if the frame heats up a bit faster now which indicates bettee dissipation. I think it's more important to monitor battery temps anyway.
No closer to finding the solution to any of this, but I can second the crazy-high/static reading behaviour on the Mi 9T. Elixir 2 reports 3700°C as the CPU temp (also only reads 0% usage as well, but that's not necessarily relevant) and CPU Monitor seems to vary, in use, between 35°C and 38°C, but normally sits on 36°C or 37°C.
Currently running: MiUI global 12.04 (stable), but NOT rooted at all.
Again, all other sensors seem to be working fine.
What is the meaning of PM6150-tz ? whats that?

I know this is probably too late now, but the pm6150-tz was actually the Power Management IC which I think is in charge of device charging and/or CPU/ROM power management. The tz means it's the thermal zone (thermal sensor)
This problem is solved by installing AnTuTu Benchmark and enabling CPU temperature monitoring. However, if you wanted to use a different one with more features, try using Scene6 app. (If you dont mind it being a paid app and having still most of the app in Chinese).
