Hi all, anyone feel the s21Ultra is pretty warm after few minutes use?

My normal usage like web browsing, social apps(fb,whatsapp), shopee, watching youtube, all causing my s21ultra feel quite warm and it's uncomfortable to hold it long. is that normal?

Ofcoz, using camera and gaming make my device burning.

coming from note 8, and my note 8 only get hot when gaming, normal use quite cool. I suspect I got the defect unit sad.gif

Check background app usage that mybe cause your phone burning, so far so good here
*
Did check the apps usage, nothing abnormal.
I put most of the apps to sleeping and I think it help a bit.

QUOTE(yayiyu99 @ Feb 3 2021, 01:10 PM)
Yes it is hotter due to the higher refresh rate at 120Hz and also higher resolution at 2K. Please test it at 60hz refresh rate & Full HD if it cooler.
*
haha, tried use FHD and 60hz, and already used to 120 hz so hard go back to 60hz mode.
Thanks for advice and I felt it cooler bit in 60hz FHD.

Dont tell me this .... I plan to buy s21u now ... This is bad news if it is getting hot.. I hate my n20u always warm or hot ..........
*
So far no much ppl complaining the phone getting hot in normal use, except gaming and using camera.
Probably using a phone case better, now I didn't use phone case so my hand direct contact on phone ,can felt the heat on metal phone frame quite warm.

Mine reached 40+ c during gaming. I still hold the phone like normal while gaming with no case. Tahan only the heat. Sometimes while I extreme gaming I feel like my phone giving out steam from behind, very hot. My Ultra still handles the heat better than my S10 plus, so far very impressed with the performance I am getting.
*
I use CPU monitor app to check temperature, normal usage CPU about 36-40'c, battery around 35-37'c.
No yet check the temperature while gaming/taking photo, but i guess can go up to 45 easily

Its an exynos thing haha

If you try snapdragon cool as ice at every tasks

laugh.gif laugh.gif

I don't like malaysia samsung exynos also. lol.gif
My Note8 is HK set with snapdragon, quite cooling for normal use.
But this time SD888 overheating issue is really bad, performance exynos 2100 not too far from SD888 so I just give it a try.

Bro I saw you are having dual sim as well. Was wondering how is your overnight standby time? For me its 4-5% drop over 8hours with Wifi turned on which I find is pretty high still
*
over night standby time quite bad for me, briefly 5~8 %.
Probably should schedule a routine task to turn off sync or everything for night.

QUOTE(bennedict82 @ Feb 4 2021, 11:40 PM)
How long you have been using your phone? 1st day 2nd day? It will be hot for about 3-5 days.. due to some learning pattern too... after that, should be cool down. Matter of time.
*
shocking.gif that interesting, got my phone on 30th Jan, but I just did a factory reset and wipe cache partition, have to go through the battery learning pattern again.

Guys I just got my s21 , wondering if you guys feel the phone is quite warm / hot even just browsing around and not doing any intensive task . Should it be like that ?
*
Yes, my s21u also quite easy to get warm and hot at beginning. Getting a bit better after few days usage. Still quite warm but more acceptable or maybe i used to it already 😂

I noticed if I had the phone on battery saver mode with cpu speed limited , the phone stay relatively cool most of the time.

Use 60hz and FHD+ also can help the phone stay cool, but most of time i keep 120hz and QHD+… hahah
