charge temperature - Xiaomi Redmi Note 4 Questions & Answers

I have redmi note 4 . During charge my phone it becomes hot.. i installed cpu z to check temperature...I found that chg-temp is 55 degree during charge and 46 degree without charge in draining ....so is that normal or not

Depends on ambient temperature but 46 degrees is way too high. It runs cooler even when doing heavy tasks like gaming even when playing asphalt 8 it never exceeds 40 degrees. It becomes more hot when charging although it never exceeded 43 degrees while charging. It is one of the coolest device.
55 degrees is way too high it never touch that when holding it under the direct sunlight in summers when outside temperature is around 50 degrees. In this condition mine mine never exceeded 50 degrees.

I reach 40°C when charging, playing EverWing, and listening to Spotify for 2-3 hours non-stop. Granted I'm indoors with ambient temperature of around 20°C. Charging, playing, or watching videos outside in direct sunlight will greatly increase SOC temperature, specially if your phone is the black variant.

In Egypt ambient temperature reaches 35 c so is it affect my cell phone temp

Also I am asking about charge temperature in cpu z program.....other temperature in my device don't reach 40 c but only chg-temp reach 55 c

Ignore it. Its fine. Not for our use. One of the temp in this showing 78 degrees.

59 degrees Celsius too hot for CPU

When I first got my phone and put a case on it just browsing the web got it up to 59 degrees Celsius or 138.2 degrees Fahrenheit. I looked at some other threads and people said that 60 degrees Celsius is nothing for a CPU, but then other people are saying that it can fry the CPU. Now that I have restarted the device the phone stay much much cooler. I just want to know what a dangerous temp is? Some people say that damage can occur around 60-80 degrees and other people say they have had their cpus hit 90-100 degrees Celsius.

I'm assuming you mean Fahrenheit. I would say 90 - 100 degree is normal-high when running games or heavy applications. Really when web browsing/idle 60 - 80 would seem like the average.
Edit: I see your calculations now. No, 138 browsing the web is not normal - And beings that the boiling point of water is 100 degree Celcius, that certainly is not acceptable.

nope celcius. mine idles at about 93 degrees Fahrenheit.
Edit: Ok, thats what I thought. It didn't stay there long and a restart seems to have corrected things. Do you think that could have damaged it? I just imagine it was a app hogging resources, maybe just chrome being buggy.
with that said the thermal shutdown point for the nexus is 110 degrees celcius, however it starts throttling the clock speed at 60 degrees. some people have claimed to have got it there.

CPU has 68 oC after 15 minutes of playing

My 2 days old Huawei MediaPad M5 8.4, after 15 minutes of playing 3D game (War Robots) reaches very high temperature. It is very uncomfortable to hold it in hands. I measured with app that CPU temp is 68 but battery 40 degrees Celsius (which is 154.4 and 104 F).
Are these temperatures standard? Or should I complain it to Huawei?

Hey..i have the m5 8.4 since 2month now and i can say that you dont complain to huawei......for me it is the only negative thing of this device.......dont worry that it could overheat...........using it intensive for playing games and until now heat doesnt harm my system.........
ps....hope the gpu turbo bost feature in the coming update will help us.....

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?

My poco f1 shows Battery temp below 45 degrees and cpu Temp reaching 93 degree centig

My poco f1 shows Battery temp below 45 degrees and cpu Temp reaching 93 degree centigrades in antutu testing is it ok or this is worrying?
If it's momentarily, it shouldn't be a problem. If you feel the phone is hot in your hand, it also shouldn't be a problem short-term. If the phone is hot most of time when idling or doing non-intensive task, then you should worry.
My previous samsung 2012 phone could take temperatures up to 60°C for battery and 120°C for CPU. If it reached that temperature, the phone would automatically power off. Even at 80°C it began to throttle the device and tried to cool it down. I imagine something similar is implemented for this phone (though I haven't confirmed it).
every time during testing it reaches that temperature for a few seconds and then comes down .this happens for at least 7-8 times during a single antutu benchmark testing.

Is normal high battery temperatures in the Poco?

When I use the phone, the battery playing even reaches 44 ° C and at rest the normal is about 36 ° C. After 40°C it's chargin slowly
looks normal
