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?

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
What do you think the average temperature should be for just moving around the UI on the Nexus 4?

depends on a lot of variables. battery temperature? cpu temperature? surface temperature? what temperature is around you? are you holding it tight? is it in a case of some kind? rubber case? is it set to the highest brightness? is it plugged in?
Lets say half brightness, not plugged in, and room temperature.

temperature of what? you can get two temperature readings from the nexus 4, battery and cpu.
cpu, whichever one causes the most heat on the back which I imagine is CPU

that could be either, lol. but their temperatures can vary greatly. the battery temp should be room temperature to 104F, but can go lower or higher depending. the cpu temperature should be 30-60C, but can also go lower or higher depending on use.
Hi i've just got my new S4 I9500 octacore from my carrier here in my country argentina, it came loaded with default stock firmware, but I need to know if these temps are normal.
I'm posting a youtube video so you can see what's going on... Are these temps normal, first of all
- Demand mode with throttling up to 1600 ghz ,CPU temp rises to around 75-80 C while playing modern combat 4
- Demand mode limiting max cpu to 1000 ghz CPU temp goes around 60C
So I've seen some videos of guys doing a performance test, while gaming and they checked with system tuner CPU temp and had after 5 minutes of gaming with Modern combat around 52C and with throttling mode I believe with max CPU speed to 1.6hhz so is my phone defective?
We all know there's no thermal compound or discipation on these cpu's like on notebooks.
Tomorrow I'm going to ask for another phone and see if I get the same temps, if not what do I have left flash a custom rom ? undervolt ?
I've seen some people checking the temp of the phone but only having as a referecne the external thermistor which is not an accurate way of measuring temp.
Basically I don't want to end up with a brick, as you know high temps on this Lead free solder BGA's, start to make solder joints brittle and crack. Then you come up with wifi not working, because the BGA chips's actually desoldered.
I couldn't place the link cause I'm not allowed to paste as a first time user, sorry
This is the youtube video link youtube.com/watch?v=f-tYmOgOQ34
The Exynos5 OCTA CPU can get even much higher (90C) so it's pretty normal.
About the other Videos, are you sure that what you saw was the CPU temps and not just the overall device temperature?
These are normal temperatures, you're reading the on-core sensors. Most apps and users don't know about them.

Yup I'm pretty sure it was the CPU core temp what I saw , let me show you the link from the guy who did the performance test check it here
he was using system tuner. Here this guy shows about 52 C after playing modern combat 4. Why on earth am I getting like 75C with on demand throttling ? . If this phone can reach as high as 90C as it's got no heat discipation it's going to die in less than a month. Is there any way to undervolt with the stock rom from my carrier without using a custom kernel ?
youtube.com/watch?v=Cg7VKs1EMww << check this link guy showint 52 C after gaming MC 4
Because that's not the CPU temperature he's reading, that's the temperature measured by the charger chip.

No it's not that's the CPU core die temp , I can tell you for sure cause it's the thermal sensor within /sys/class/thermal/thermal_zone0/curr_temp I opened both system tuner and cool tool to verify it

He's saying it's mostly the sensor on the battery charger, but I could veriiy it's the on die cpu temperature.. the external temperature he says it's the external thermistor and it's not the one I'm using , not even the one from the guy on the video.

You're right, System Tuner seems to read them out correctly (he updated the app). But it still doesn't matter. The temperature drop from 75°C to 50 range within a fraction of a second, that's video is still worthless since he still didn't have it running in the background.
These are normal CPU running temperatures.

You have an I9500 as well? what temps are you having while gaming .. talking obviously about CPU core temp , not the external temp diode which gets the battery temp, being useless.
Hi , same temp on my i9500 I thought it was my phone defective but no
its normal

Wowww ! holy jeez really? Can you post more details , take some screenshots. Are you running custom rom or stock rom from your carrier?
What temps are you getting while gaming ?
When did you buy the phone
cheers~!
I think its normal
My Note 2 CPU temp gets around 75- 80c ( but i think the device from outside feels like 40-45c ) after 5 - 6 minutes of running the CPU on full load in cold room but as AndreiLux said the temp goes to around 50c in eye blink
and don't forget Exynos 5410 is way more powerful than 4412 :good:
Andrei I didn't know you were in charge of developing Perseus Kernel for the S4. Would it be good if I change the kernel to yours, I was thinking in undervolting it to improve the temps. Have you tried undervolting it ? and know which are stable voltages for both Little and Big arm ?.
On the other hand , can you guide me abit on flashing, I got my carrier stock rom now and I don't want to screw it up or brick it. It's not unlocked. So can you guide me out how to flash say the best custom rom ? ( is it wanama ) and how to flash your kernel perseus ? do I need to download the rom separately and kernel aside ?.
I have been using TempMonitor app with great accuracy, it includes temperature in the status bar and you can easy check the actual CPU temp.
My temp readings is about 38C to 55C depends, Skype goes higher temp up to 58C
I9500UBUBMF3
Nothing much to say,
only bad luck the unit is defective temp jumps from 35-80c, usb works only first 10min after you power on the device ,i live in Vienna warranty is not worth anything here because
phone is purchased from world wide distributors California US(EU warranty, and US warranty not the same thing).
Phone act same with official rom and with custom rom (temps and usb fault)
for charging i use wireless charging kit ,the usb connector is not broken or defective in any way ,
Cheers

So you say the unit is defective yours? it jumps from 35 to 80 C in what kind of tests? can you detail me a little bit more. Mine jumped to 80C while doing heavy stress tests like gaming on modern combat 4 if I left the unit to throttle doing the governor scheduling of the cpu from 250mhz to 1.6mhz.
I need you to install a couple apps, Cool Tool so you can see in real time the temperature , go to labels , choose custom label --> advanced tuning --> custom label choose prefix and write CPU TEMP , select postfix and write @ C. Then go to advanced and under Custom Label Path write down /sys/class/thermal/thermal_zone0/curr_temp that way you'll have a status on top showing the cpu temp.
If you can please install it so you can see how the cpu frequency it's jumping from a low state while doing any task I'll be grateful
Hi, installed cool tool same temp values as in temp monitor , i did a screen record with some simple tasks so You can see how phone act , uploading rar now on zippyshare.
Sorry for the late reply but I was at work

What is the average temperature of CPU and Battery on your Z3+ ?
Mine is about 45-50 CPU and 42 Battery.
Could sometimes get up to 70 CPU and 47 Battery "Too hot for a short time at random times".
Battery life is about 4:30 SOT.
Is that normal for this device? What apps do you use to regulate the temp and increase the battery life?
Same with me on stock or custom 7.1.1
is your cpu 45-50c idle or when you are using?

it varies from 40 to 50 on idle.
However, it's summer here and temperature is kind of hot "About 42c"
I don't know if that's related.

yes, room temperature affects temperature of the phone on idle
I live in Turkey/Konya, idle temperature is low. But when I started to use the phone, it gets hot after 4-5 minutes later. Even though I am a light user, this heat and lag poblem made me hate Sony. I will never buy a Sony phone again. Some say new XZ Premium and XZ1 don't get hot so much but I can't trust them. If you have a Qualcomm Processor phone, heating becomes a scourge for you. I used and using Samsung Exynos phones but they never had so much problem about heating so much.
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.

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).
