Brand New Galaxy S9 Overheating

[S h u r i k e n]

Hi, 

 

I got my Galaxy S9 (64GB, Exynos) last week. Out of the box, immediately after setting up, the phone became extremely hot all over, even when left with the screen off for 3 hours, it was still painfully hot. 

 

I returned that phone and got a replacement - the overheating appeared to be fixed.

 

Yesterday however, my new S9 started overheating. I downloaded aida64 and it said the battery temperature was 46° 

 

I noticed that this seemed to be triggered by a settings change - but I can't pinpoint it.

 

All I changed was:

 

Navigation button order

Ringtones

Wallpaper

 

No apps (apart from aida64 were installed) 

 

I have tried a full factory reset

 

Have tried an update, the problem still persists.

 

 

Is anyone else experiencing this? Am I just unlucky and received a faulty replacement?

Just got my S9 (Snapdragon) about a week ago and the temperature is around 36° Celsius and it doesn't seem very hot to me. I have noticed that youtube, web browsing and such can cause a decent raise in temperature.

The exynos version definitely is not good power efficiency wise though that does seem a bit unusual.

Yes, understandably, since driving a 1440p panel with a soc in a closed space is definitely going to create some heat

check which apps are running and also the battery usage per app

All apps are closed, forced all non critical services to stop - problem still persists

 

Battery usage per app is minimal

For basic UI tasks and web browsing, the high resolution is not a problem. Web browsing itself is an intensive task though.

 

Due to summer heat, I've locked my phone to power saving mode (1.05 GHz) as it would get very hot when browsing and watching video. If you reside in a hot climate, using power saving features to reduce heat may be a good idea to prevent excessive throttling. Are you using the phone or running anything in the background (Facebook) when this occurs?
