Heating when taking pictures? - Nexus 7 (2013) General

why does cpu temp reach nearly 60 degrees when i only use camera to take photos for minutes?
is it ok?
I read a chinese news reported that it is vulnerable to damage by overheating in darkness cuz it has to raise voltages to keep white balance.
discuss.

Battery Temp/CPU Temp

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
Sent from my GT-I9000 using XDA App
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?

[Q] Phone overheats while gaming

Hi,
I've been using G2 for the past one week. Within minutes of playing a game( `10 mins), the phone heats up a lot at the back where the camera is placed.
I dont even need to play high end games like NOVA 3. Just regular games like Candy crush, Cut the rope etc heats up my phone real bad.
It heats up so much that its impossible to touch it with your hand.
Please advice if anyone has faced this issue.
Regards
Georgi

Same with me, but only plants vs zombies 2 may be its just one game.
Please don't post same question in more than one thread. Your question belongs in the question and answer section where you have it now also. Not here please.
Same here. Maximum overheating is seen during plants and zombie 2.
Hi,
Guys you realize that you have a quadcore at 2.26 Ghz... And when you play a (heavy) game or some other heavy tasks (browsing in 4G for example) it's normal that the CPU heats, right?
Temperature is very subjective without reading the CPU temp with an app, it feels hot in your hand (you can have cold hands and in this case you feel much more the heat) and it's hot because the CPU temp is about 90°C is different...
Heat and overheat (or "maximum overheating" like above ) is different too..., in any case there is a thermal throttling that prevent overheating. Our CPU shutdowns at 120°C so there is a little room... Even 80°C is nothing for the CPU...
Even 90°C for the CPU temperature is almost nothing (for the the stressed people) and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
And if you speak about "overheating" when playing a game or browsing while charging your phone...
Check your CPU temp with an app and report here...
It remembers me all the threads about "overheating" in the Nexus 4 forum...
I will definitely try installing a temperature app and will report the temp soon.
I'm worried that the heating takes place near the area where the camera is located. Can this have any adverse effect on the camera?

I cant vouch for a smartphone camera in general, but I know I had a newer regular old camera that sat in the sun and the heat for a day, and was perfectly fine. I don't see the heat damaging the camera.

Sony Z5 Heat Emissions

Hey guys,
I know there been a few threads on this issue, but none really tells me what the normal heat temperature is. I just got my Z5 a week and a few days now and noticed since using the phone that browsing lightly the phone heats up quite a bit. I know with gaming it would heat up a lot more but wow does it heat up.
The part it heats up mainly is the top half of the phone. When touching it at that heat level it doesnt burn majorly but just feels uncomfortable to hold. This is me playing Need4Speed No Limits for about 10mins and the heat gets that way. Also taking videos and photos it tends to heat up a lot which is understandable.
What i dont understand though is when Im just browsing google play store then it heats up quite a bit. Is it suppose to heat up so much so often?
What is the normal heat levels for this phone? Im not sure what would be classified as normal temperatures. Last time I used a high end smartphone was with the Z1 and that never heated up as much as this phone at all.
The Snapdragon 810 SoC runs hot so the Z5 has two heatpipes to remove the heat from the chip. You're just experiencing where that heat ends up.
Note: phone gets warm while charging so gaming+charging together will be even hotter.

I see. So its basically pushing all the heat there. Kind of makes sense. I never use my phone while charging simply cause it generates a lot of heat. Regardless of the phone I use.

My Z5C always runs cool, it never heated up not even during initialising everything. I never game on the device but I do take quite a lot of videos/photos, browsing, texts, whatsapp, email, youtube etc etc.
Maybe this is another thing that varies between different handsets.

I find that so difficult to believe. Im typing this reply and its heating up quite a bit. U must be lucky.

Z5C has a smaller screen with less pixels, that's not a fair comparison to the normal Z5
Xperia Z5 Temp
Guys would like to know about the temps that I'm having with my Xperia Z5. My version is E6603 rev 3.
I made the following temperature tests and used the cputemp as app for monitoring. In all tests I started with the cpu temperature around the 34 - 36 and 26c environment
Shoot in 4K with phone on the table
30 minutes, max cpu temp 70c, 46c battery
Shoot in 4k with minimal contact (phone over two pens)
10 minutes, max cpu temp 70c, 46c battery
Shoot in FullHD @ 60fps with minimal contact (phone over two pens)
Almost 5, max cpu temp 71c, 48c battery
Shoot in FullHD @ 60fps on the table
15min max cpu 70c, 46c battery
Playing Relic Run (tomb raider)
max cpu temp 62c, battery 44c - 46c
Playing Real Racing 3
max cpu temp 56c, 44c battery
Comment and compare the temperatures. What do you think?

What is the normal CPU temperature ?

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).

Mi 9T Incorrect CPU Temperature Readings

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.
