I have a feeling that the battery temp reading we see on our phones is actually the cpu temp or motherboard temp
I ran setcpu stress-test for about 30 minutes (phone unplugged) and the temperature got to nearly 50 degrees Celcius
Feeling the top middle area on the back of the phone (and the same area on the screen on the opposite side) that area feels hot, the battery however is stone cold.
So... Battery Temp = cpu temp?
Anyone got an opinion on this? Its important for the overclocking crowd

I can tell for sure that battery and CPU temps is always the same but where is the sensor?? On the battery or the CPU?
If I was designing this phone I would put it on the CPU as it is more likely to produce heat if overused.
However I just experience a drastic temp raise from 33C to 41C in 1 min just after pluging in the phone. I was using it but noting eavy. I was only changing some startup setting with an app called Autorun Manager. So it might be related to battery but according to what you said it is more likely to be located on the CPU.
I currently have one of those extended batteries and tmeperature rises to 52 C after 10-15 min of playing gameloft hd games. I have measured phone temperature with an infra red thermometer and battery was 30-32 degree and upper part of the phone (between sim card and camera seemed to be as high as 49 degree) so the sensor must be on the cpu or motherboard, not anywhere close to the battery.
Unless battery gets hot inside and is cold outside for some reason. And sensor is simply inside the battery like in a laptop battery (google: 'How Lithium-ion Batteries Work' and open first result)
In my personal opinion manufacturers wouldn't waste space inside the battery for additional sensor that looks pretty big on the website above. Furthermore a hot battery would be hot throughout its casing too.
Which sensor you people are talking about?

Temperature sensor. Download temp+cpu from store and you'll know
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?

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
Hi everyone,
Today my S4 gets overheated so I installed app to control CPU temp, but can someone tell me what is a real CPU temp? Coz two apps shows me different values.
CPUTemp is on overlay and Cool Master is on main window. What app shows real temp? And my CPU temp is ok? Coz I wasnt using any heavy app when getting screenshot, its normal state.
Sent from my GT-I9505 using XDA Free mobile app
I have bigger difference using same apps.
on standby cputemp app shows ~30. Simple browsing - 40. Candycrush gaming or intensive browsing - 50-60 degrees.
Cool master shows almost -30 degrees too. Don't know if any of them shows correct temperature. I believe cputemp results are more accurate
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).

CGB overlay does the proper temperature reading.
