Z2 CPU temperature and heating on your phone - Xperia Z2 Q&A, Help & Troubleshooting

Hi,
since I updated my Z2 (D6503) to LP 5.0 my phone is heating pretty much. After 10 min. of using (doesn't matter how) temp. foes up to 38-39 degrees of celsius, and after using for a while like an half hour, it goes even up to 41-42 degrees (but it is also very very hot in room in which I use it).
So, I just wanted to hear your opinions about this, is it normal, do you have the same issue and can it be corrected somehow?
That's all, thanks in advance to all.

Mine's CPU almost hits 70 degrees celsius. Your temps must be battery temps, cause mine are the same.

38-42° Celsius? You mean Battery temperature right? My phones CPU was about 58-66°C after installing 5.1

[Q] Otimus one battery temperature error?

hello i got an optimus one...
ok ther is not a cpu temperature sensor.
but my battery report 2.3 °C .... is strange
ther is some app that correct read battery temperature on p500?
tnx
try Elixir
i have try
elixir report battery 2.5 °C
i have trai stock 2.2 , void and devoid rom and i have the same error...
is my battery fault?
Why do you want to know the battery's temperature ?
why not? are your battery temperature sensor working?
Not working here either
From what I've seen in the past month since I have this phone, nobody is able to get a correct reading of their battery temperature, no matter what application they used. The LG Optimus One always reports the temperature in the range of 2.x - 3.x degrees Celsius.
So, scoppyxda, your phone and battery are actually fine, don't worry. I hope this issue is fixed with the next Android version (2.3).
everythin reports it wrong except batteryminder..search for it in the market
I guess that the real temp is divided by a factor of 10. I say "i guess" because when i do something power hungry (like listening to streaming radio) the temp raises to 3.8 and the phone bak is quite hot.
I think it shows temp in deg. Fahrenhiet by default and app has to change it to deg. celcius.
Mik can fix this 5 mins if he spends time
I played with this a while today - I tried to multiply temp by 10 and voltage by 1000 in battery driver.
For voltage, it worked (see screenshot). When I tried to multiply temp by 10, apps showed it correctly, but android yelled that battery is overheated. So, android API gives wrong values to applications?
Make the api assume that it's normal ;p
Maybe the fahrenheit temp is actually the celsius temp.
And the celsius temp is the wrong temp.
I think it's...
Correct Values
While using myPhoneExplorer (usb connection) i get more realistic values. The monitor gives me figures in the range of 23-28 deg Celsius.

It isnt, battery driver returns value in celsius, fahrenheits are calculated from it by android.
I've posted the same question in the void forum (which is the ROM i'm currently using) it seems to be a problem with the model of the phone itself. So everyone will have the same results. I was told to just multiple the value by 10 to get the accurate degree.

CPU Heat

Hello everyone. I'm having a little problem with my S3. Whichever rom I install I'm having a CPU Temperature issue. This is same on the stock rom as well. I don't know if this problem persists for a long time. I just realized it 1 or 2 weeks ago. Currently I'm using qaraqumus's QS I9300 KK Final(OE1) rom with boeffla kernel installed. My temperature is mostly around 40 to 50 degrees. In my town the temperature is about 35 degrees (I don't know if this has something to do with my phone's temperature.) When I leave it and don't touch it phone cools down to 40 degrees. But with a room which has an air conditioner, it cools down to 36-38 degrees. Whenever I pick up to phone and text message to someone or look at the Twitter (minimum usage) its temperature goes up to 45 or more. Is this normal? Or do I have to get my phone serviced?

heating issue

sir, can u help me, my opx always getting hot, just open chrome battery temp. up to 46C, not normal, why?i dont use another apps, i just install clash royale, bbm, WA,in CPU-Z apk GPU Load always 0% its normal ?
i have intall much rom with wipe blablabla, but always getting hot
46 is not a a concern, although mine stays around 30° when idle.

do you have any idea solution ?can u share ss cpu-z with gpu load is working ?
You dont have a problem with your CPU temp. The only thing that could be causing the heat would be background jobs. If you're not sure that there are not unintended background jobs, just do a Factory reset. Stop flashing for a few and stop using your phone 24/7 and the temp will lower.
Phones and tablets with SD810 and atom x5-8300 can go up to 86 degrees, then you're sure the cpu will throttle (and performance will drop). 46 is very normal, mine went up to 60 degrees when charging and flashing, which is still no problem.

Peak CPU temp under load.

Hi, what is the normal peak CPU temperature for the phone? Mine is going above 90 on the antutu stess-test. I feel it pretty hot around the back camera. Is this normal or my unit is faulty? Thank you.
Is that degree fahrenheit or degree celsius?
Hi, it is Celsius. Please note this is the CPU temp. The battery temp was in low 40s at that time.
Could anybody please run the 15 minute Anutu stress-test and check where the CPU temp goes in Celsius? Thanks!
I've seen several videos on YouTube, the temperatures never raise above 45 degrees celsius, even after an our of playing PUBG. So I think there's definitely something wrong with your device.

It's odd but I have bad experiences with the older 800 series of Snapdragons. I'm still holding off Pocophone for the SD636 or SD660 until I'm sure it doesn't lead to me frying an egg with the phone after playing for 30 minutes.

Playing youtube 4k video and the CPU is around 40c as well. Please note these are CPU temps I am talking about, not the battery temp which is in low 40s when the CPU goes above 90.
If possible please run the antutu stress-test for a couple of minutes and advise on the peaks. Thanks!
Just played pubg for 20 min on the default settings - CPU temp peaked at 46 C. I guess this is normal but why does it spikes in 90s on the antutu stress test...
Run Antutu test again 264k, temp spiking in 80s here in there at the end was 33 C.
Please advise if this sounds normal.

That 80c spike has got to be erroneous. That's 176F, which would melt the back cover and everything else inside.
yes it is true
I have the same experience. Run antutu and watch the temps using CPU float when it starts the CPU benchmark. Boy, it went all the to 95 C then goes back to 60 and 90 until the cpu part is finished. While gaming, this wont happen as the cpu will throttle depending how hot the battery temps. I posted the thread here at https://forum.xda-developers.com/poco-f1/how-to/phone-throttles-cpu-gpu-t3839525 so you can see the effect of battery temps on cpu performance.
My question is more like how antutu's cpu test really stress the phone. I run HWBot with cpu float and the maximum temp i was able to get was like 70-75 C while antutu can shoot the cpu up to high 80's to 90's in even cold phone state.
I think it is due to the fact that most of the companies optimise their software in such a way that the benchmarking apps consume the full CPU usage regardless of thermal throttling. OnePlus did this with their phones. My old leeco phone had the same optimization that it automatically utilized full CPU power in benchmarking apps. So I think similar is the case with Xiaomi's Poco f1
Poco F1 cpu temperature reaches 96 °C in Antutu

Mine too.It goes up to 96 C , then 60+., 70+ then again 96 degrees Celsius in Antutu stress test.
And in heavy apps goes beyond 60 °C.
I bought the phone from Romania, where I live.
I have a different problem, i too use poco f1, my benchmarks are around 4500 at 36 degree celcius wheras it is 8000 at 30. So is it the same with everyone?

Performance Throttling Overheating Device Temperature

The lower scored benchmark is at from idle of around 40C (CPU temp) while the phone is in the room. The higher scored is when I placed my phone in the freezer and let it cool down to around 28C (CPU temp).
Why is the phone so hot even at idle? Do you r phones go as high? What are your ambient temperatures? I'm in a tropical country and it is around 29C here right now.
The battery temp is only a degree or two lower than the CPU. It's terrible for the battery to be at this temperature.
Mine is around 36 C after 30 min of browsing . inside room temp is around 22 C.
Yeah, Mine also get so hot like 40 -45 like your after 20min of used.
But our Poco got cooling system right, then why like that?
My previous Moto z play was not like that ?, It was only heat while charging because of rapid charge.
It's coz of that garbage of IU called MiUI. Every update it screwed something.

Looking at OP's screenshots, i don't think he's been using MIUI..

Mine is sitting at 31.0 degree celcius. Could be that you have many things going in your background?
