Question Does poco x3 pro get hot when playing or recording videos?

[leonskjti]

Hi, I recently purchased my poco x3 pro, but sometimes when I play black desert mobile I feel the device is kind of hot next to the camera (where I think the processor is). Is it normal even with liquid cooling? And another thing, yesterday I recorded a 3 minute video, it was with a plastic cover and under the sun, the cell phone also got hot. It's normal? I had read in some forums that the plastic back does not help the device to dissipate heat, is it true?

Yes is normal this isn't hot he is just warm!
I have poco X3 Pro too and is perfectly fine.

Can I be carefree then? Would I be better off playing without a protective cover?

But can you tell me if the plastic rear shows that the device is hotter?

No , look on Iphone 12 is full glass and alo and is the hottest 5nm device.

"If you have 2 cups of equal thickness, one glass and one plastic, the plastic cup will insulate 5-10 times better than the glass cup, because the thermal conductivity of plastic is 5-10 times lower than than that of glass. The physical reason for this is that glass has a more regular atomic structure than plastic does. This allows heat to transfer faster in glass than plastic."

So No, Plastic is better with heat in devices.

Understand. Thanks.
Another thing, this morning I recorded 10 minutes of video, the atmosphere is cool here, and the CPU reached 48-50 degrees Celsius at the end of the recording. It's normal?

Yes only CPU that correctly measure temp is 888. This temp are fake. Look for temperature of battery and add 2-5 degrees of Celsius.
So everything is under control

Once i was playing LOL Wild Rift with every graphic on top and charging.. lol, my poco x3 pro was HOT. But then i realized it was managing the temperature just fine because it wasnt charging. Like, charge cable was connected but battery wasnt increasing nor decreasing, so temperature management was working.

I spent a little time doing tests with the device. Changing applications, whatsapp, telegram, youtube, and using the power manager to measure the temperature of the CPU. It reached 38 degrees, using in normal mode, but as I said, quickly changing applications. It's normal?

Its normal bro, me play pubg smooth - extreme for 2 hours its playable not too hot

As a reference,

ArrowOS 7th May Gapp build debloated
Etherious kernel
no Sim card
using just WIFI and the phone speaker
auto brightness
watching in house
room temperature 29~31°C
no air conditioner
Smart charge upper limit/threshold set to 65%

Phone under the sun obviously will get hot. Don't you feel hot under sun shine?
Also under sun, the screen will likely be auto-bright in maximum, so it gets hot.

As for gaming, MIUI has an built-in app for it. I wrote a simple guide.

If you look at the construction of the phone, the "liquid cooling" (heatpipe) is actually in the Front of the device, runs from the processor (which is indeed just to the side of the camera assembly) to the middle portion of the device, encased in the metal backing of the screen assembly.

In my experience playing pokémon go, the screen does indeed get kinda hot, even with low brightness and playing in shaded areas, but I would say this is a good thing, the phone just uses the big area of the screen to dissipate the heat from the processor, because as some said, the plastic backing doesn't provide good dissipation, so I wouldn't worry too much about using a rubber case, it's desiged to get warm and will throttle down the CPU to cool itself down if it heats too much!

Thanks guys! One last question. What would be the maximum temperature that the CPU can reach in game without having any kind of problem or burning the hand? I found a better method to measure the temperature, the Power manager ...

Remember that CPU temps are the same as battery,every every cpu beside 888 can not display temperature. This CPU temps are algorithm generated

If you want Cpu temp always use battery temperature , cpu temp is 1-2C away for it
Most smartphone beside 888 do have any sensors on cpu to measure the temperature so they using algorithm to predict what is temperature.

Only thermometer in most smartphone are with battery .
