Thank you

I have the same issue with my s20 ultra.

I did the update and while it was installing it it overheated and in around 1 min it lost 5% of battery. 

I opened the camera and it started heating up without actually taking any pics or videos so I closed the app so it doesn't overheat.

In around 5 mins it went from 98% to 91% and the brightness is halfway .

There's no sim card in it yet so signal wifi etc are all off .

 

same experience with my galaxy 20+ .
the huge battery mah is a scam. samsung should hsve noticed that their battery is not good enough for their so callex flagship phone. fyi it is overheating when using camera or using the phone in room temperature . just using social media app. im just using i.g. and facebook. but still its draining the battery so fast. already contacted samsung and they remotely checked my phone and the staff told me its not faulty. so i ask her. so whats the main reaskn why battery is draining fast. she said. coz you are using your phone. omg that answer is unacceptable. hahaha. for 4500mah battery . it only takes 5 to 6 hours battery life. this freaking phone cant withstand the social media app? #samsung gotta be kidding me

S20 ultra 5g is overheating and start getting hot 🔥 faster after the recent camera update.. anyone can advice me how to solve this problem..
I'm a Samsung user since note 8 and I never had any problems as such before.. but now it is truly disappointing what is happening.. I switched the 5g off and not using it just because I was told it was the reason of overheating..

please help 🙏 ..

honestly this is because of this region receiving the exynos variant instead of the snapdragon which is much better.

I am facing the same issue.  Heat raises like iron when I use camera zoom and battery drains quickly. I want to know this happens only on Exynos Processor version?

 

aparrently yes, all complains are coming from exynos users.

I was having the same issue with my S20 Ultra 5G - Model - SM-G988B (the B stands for Exynos 990 chipset and the U in its place stands for the Snap dragon chipset). just opening the camera App when the phone was at about a cool 29C degrees (not recording video or taking photos) or on a WhatsApp video call, and the phone temp would shoot up to 41C or 42C degrees in a matter of 3-4 minutes. (this is all happening in a room with the aircon switched on and with the room ambient temperature at about 23C - so, no - I was not in the sun) I had taken the phone to the service center and they were of no use what so ever since my warranty also ran out. did a factory reset of the phone and it was still heating up. However, I manually reinstalled the firmware using Odin (the phone did not do a factory reset through this process even though I was ready with a backup) and I think it worked ! After the manual reinstall, I used the camera app to test it....thoroughly (zoom in and out, change camera mode, switched from main camera to selfie camera and vice versa used the 3D scanner app, used duel recording)..for about 15 mins continuously and the max temp I got was 36C which is about normal for all phones. so now it takes about 10 mins of continuous use to get to 36C and just under 5 mins of closing the camera app to get back to less than 30C which seems pretty standard. Im guessing this might work for for both chipsets... no promises. Please do the Manual firmware reinstall at your own risk and make sure you download the right firmware (as per your location), Odin software, PC drives etc and follow the instructions down to the letter (see below guide link). Good luck. :)
