Please dont rely in this single youtube. I watched many youtubes. Most said 888 almost same as Exynos ... sd865 still the best in term of stability and power saving. This youtube makes you scare, it said Exynos temperature spiked up to 68deg celcius. I am afraid he get the defect unit to test. Jerry passed the phone to him after tortured kut.
Black only good when the phone will be used in total naked.

I think there might be an issue with how Antutu reports the CPU temperature. I installed it on my S21 and sure enough the temperature was about 52 celcius but the phone feels normal. I didn't even use it much before installing antutu.
Then I put the darn thing in the fridge like the video for 10 mins

and the temperature is still around 50 celcius.
So I installed another app, CPU monitor and it shows it is only around 30 to 34 depending on usage, very close to the battery temperature. I think the Antutu app is reporting false temps, probably due to bugs.
Edit: So I tried a bunch of apps from the Playstore, just search for CPU Temperature, chose those with 4 star or more ratings and found that a lot show errors that there is no CPU temperature available and just randomly throw a number at it if it does display something. The highest I got is 65 celcius from a 3.5 star app called "CPU Temperature - CPU, Memoryu, etc etc" by Kami Dev. I think at this point there is no need to worry about the CPU temperature. It is most likely a false report.
