Hi i wonder if anyone who has received their S20 has experienced some overheating? I upgraded from my S9 which occasionally was hot during charging and heavg usage whereas the S20 is getting really hot from normal usage like phone calls or using the phone for longer than 10 mimutes and no where near the heavy usage the S9 went through. Any ideas anyone?? Thanks in advance.

not attacking you but that damage is certainly a drop damage, the cracks started from the side which got impacted, the soc heat cannot crack a back glass especially in the glued to the frame area and at that level there is not the soc becuase it is in line with the cameras not down there....

I conducted tests using the FLIR meter.

The conclusions are as follows ... applications for temperature monitoring reduce the actual temperature about 2-3 degrees.

The top two photos show temperatures during the movie playback on youtube after 4 minutes.

Two lower ones with benchmark running (for about 3minutes).

If you have ideas for other tests, write 🙂

Interestingly, during "games" the phone heats up more on  front upt o 47 degrees. Room temperature 24 degrees.

I hope we will not have fire or exploding s20 ... when outside will be over 30.

christ

no phone should go up to 45C+ 

is not normal and acceptable 

 

Samsung better fix this before someone's gonna have an explosion incident 

and also - how come is happening so much this year but not on other Samsung phones

clearly something not right on the s20s

I hope they won't say it's a cosmetic thing and they won't change the glass or phone for free...

Good Afternoon All,

 

Following another weeks worth of testing various settings on the S20 plus 5g.  I have decided to return it and exchange for the Note 10 plus 5g.  I really do like the S20 but do not wish to wait around in hope for a software patch to attempt to resolve the issue of overheating.

 

I have changed the handset to "Performance Power Mode" which does help, the phone still heats up just not as hot as the optimised mode and it takes longer to get the.  While in Performance mode you change the display res without resetting the power mode.

 

In Medium mode, it heats up quicker, than optimised (but again not as hot).

 

Next I removed a number of apps which again helped with the overheating, but I never have alot of apps on my phone anyway.  I switched off bluetooth/WiFi/GPS/NFC while not in use to help further.  All of this did not offer a huge help.

 

Once we are out of lockdown, if I used the phone as a sat nav for work within 30mins it will likely get so hot it will turn off or worst, its just not reliable enough.

 

We have £1000+ phone, with more ram than my laptop, an great processing power. A tool that offers full connections that we should be able to use at all times, but to stop the phone from boiling itself and risk of damage, delete all apps turn of the connections as use it as a £50 feature phone from the early 2000s.

 

Samsung may be able to fix it, but I will run out of time to exchange before then and if they dont I have a phone I am to scared to use.

To be honest I don't think that the overheating can be fixed with an update. It's down to the processor which is overheating from what I understand ( exynos 990 to be more specific).

nah guys.

I could write you a long and boring explanation and send you the anadtech article to complete the explanations.

I will do just the latter.

About the former the sum of what is happening is that the 990 has architectural problems since it looks like it is a 9820 with a slight overclock and decreased efficiency to squeeze a little bit more performance and due to the way cpus work to squeeze the last bit of performance the power consumption goes incredibly higher: example extreme overclocking you can go from the 5ghz of a 9900ks to 5.3 just on normal water, to get to 5.5 you need subzeri cooling and further you need liquid nitrogen and the power cosumption just from going for 5 to 5.3 gets super high like 200 more watts and the next steps are even higher.

 

Anandtech article: https://www.anandtech.com/show/15603/the-samsung-galaxy-s20-s20-ultra-exynos-snapdragon-review-megal...

 

To the one who used the thermal camera: the temperatures you got are not good for youtube but are even worse since what you read with the camera is not the temperature of the inner part of the die were the transistors are so you are reading more a T edge and not the real T junction which can well be much much higher...... from bad to worse..

This could very well be mine, and a lot of other people's last Samsung phone if they do not do damage control, at this point it looks like a scam.

eriously

what the F efffing is going on with this phone

mine starts to heat up about 5min into using it

let me confirm - i dont use games, and the phone is at 60zh qHD set up/optimised battery

after 5min of checking apps (like email, facebook instagram) it starts to heat up FAST - the worst of the heat (mind you i have a cover so that could also be why) feels like on the front side (screen) upper left - i believe that is where the chip is

 

the heat doesnt go down until 5 min after i stop using the phone - during the time the phone gets hot, the battery drains at 1% every 2-3 min 

 

may update didnt make any difference probably because it wasnt more than a security update

I mean honestly this is messed up - think about battery life over time - if its constantly submitted to such high temp

 

also i am not exagerating when i say the phone is so hot you cannot hold it or put it in your pocket afterwards

 

WHAT IS CAUSING THIS ISSUE????

is it software - i doubt - i fear is hardware

i read somewhere that is because exynos/mali setup isnt right 

did no one at samsung bother to *****ing check these things before releasing millions of phones into the wild 

do they not care at all if they start exploding again???? im sure is only a matter of time before they do - i wonder if THEN they will acknoledge this issue???

 

they have also locked super fast charging - basically once the phone heats up (so quite quickly) the display drops back to 60 and the super fast charging gets locked to fast charging - so 2 MAIN features - stop working 

I didnt pay £1000 for this - for limited usage, burning my hands, cant put the phone to my ears etc 

I also didnt pay to have samsung burry his head in the sand about it and act like this is not them or the phone when millions are facing the same issue

 

is there NO ONE here that can shed light into WTF is going on and how is this going to be fixed - if it will 

 

I cannot see my self using this phone for 12mo in these conditions, i also cannot return it nor sell it - so am in a really bad spot like many here are - SAMSUNG what are you doing about it???????

1. - Change from optimized to either medium power saving or performance mode- phone heats lesser
2. Exchange this phone tbh, I will be doing the same - for the note 20 if that is good or something else. This is just too bad

i changed the battery modes but it didnt made much of a difference - at the loss of other functionality

 

i cannot exchange it as samsung doesnt recognise this as an issue

Change it to performance, the battery life take a bit of a hit but it crosses 40 seldom now and tbh that is all I want from this now, I am okay as long as it does not switch back to 60 hz because then it feels like it is lagging.

By exchange I meant exchange for another phone as an upgrade by paying certain amount extra. As much as this sucks, we are stuck with it, if I could I would just swap it with any other phone for the same price Samsung lost a good amount of respect at least from me for this robbery of a phone

Hopefully Samsung will listen and make some changes for the best
You can wait and go for the p30 pro new edition which will be coming out soon with Google services
OnePlus have already rolled out many updates and fixed most of the issues if not all already
