**Health and Safety warning - these tests CAN and WILL cause burns, additional damage to chipset or other hardware and should not be replicated without caution at your own risk**
So as most of you reading my posts are aware, I have 3x faulty S21U 512/16gb Exy chipset devices being replaced by several different retailers in the coming few days.
I decided to perform a final test before that on something most people do, Gaming: Call of duty mobile edition.
All 3 devices are up against a A90 5G SD855 and a S21U SD888 512/16 version.
Test: completing the introduction on the game which takes about 10 mins max and runs at 1 below max performance to see where the temp and performance ends up.
Conditions; room temperature: 20°C, Optimised soft/hardware settings for full performance and display set to Max, as well as cleaned up caches etc etc.
Start temperatures: (Idle, screen off 30mins)
S21U 1: 39°C
S21U2 : 37°C
S21U2 : 37°C
A90 5G SD855: 30°C
S21U SD888: 29°C
Backup S21U 4: 31°C (Friends phone, claims all issues more or less less solved with latest updates)
Results:
S21U 1: 58°C (heat warning Shutdown)
-Front and back incl. Camera module: hot enough to cause burns to skin/fingers.
S21U 2: 54°C (heat warning Shutdown)
-Front and back incl camera, as example 1.
S21U 3: 51°C (still worked but heat warnings galore)
-Front and back the same as example 2.
A90 5G SD855: 39°C no problems continuing or moving on into other apps
-Front and back minor warmth, barely noticeable.
S21U SD888: 34°C (No problems whatsoever)
-Front and back no noticeable heat, sides minor Warmth barely noticeable.
Now, I have one friend with a Exy S21U 512 model who has no complaints and said the latest updates fixed most issues for him perform the same test; 44°C (Heat warning but no problems)
-Front and back very warm to touch but manageable in short bursts.
I would dare say that these 3 devices are as Samsung put it, 'defective units' and rightly so needs replacing.
Regardless, the final test on a S21U Exy with performance and battery problems solved in the patches still gets 10°C warmer and perfoms worse on tests that the SD888 counterpart.
Seems a little like we're getting the short end of the stick on the international model Vs the N.US devices.
Hope that helps others see the difference and help determine whether the ones who still experience problems have faults that can be fixed with updates of if they should seek replacements / repair.
Note. This is purely an informative post and conclusion from my perspective on my own faulty units Vs a few others and not a 'i hate Samsung and give me my money back' post.
If you'd like the benchmark results on the different devices just let me know:)
Have a great weekend everyone, I'll see you all in another post with the 3 new devices and their results in a few days!
