Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Samsung Galaxy Note 20 Ultra stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.

Then, drop a comment if you have anything to add!

Heat is so minimal when using the phone but have tested video extensively or gaming. Heat is nearly non existent in other tasks. I think it is actually a bit too low when charging. Seems they have the charging throttled to keep the battery temp under 100°F which limits charging speed slower than it cloud be.

My exynos variant have a high temp at idle and load. Soc idle min 42, normal uses 50-58celsius, max soc temp is 68c.
Antutu scores after loop.
1.run 540k
2.run 520k
3. run 460k

It heat like a hot fry pan. While using phone normally. if i get call. I can't even touch is to my cheek. Sometimes it feel it will burn my skin.
With my Note 9 this heating issue was even more worst. Due to overheat. I wasn't able to use camera more than 10-15 minutes. Camera app keep stopping because of overheat.
Worst phone brand. Even after having so much innovation. Samsung Note series always disappoint me.

When using Camera and try all options , different zooms , Device starts heating and gets to an abnormal temperature , this is affects the 5G signal , as it disconnects the 5G recipient automatically and turns to LTE !!

My SD version gets a bit warm just from normal tasks. And my battery life is atrocious :/ I really like this device but I may need to contact Samsung about a replacement and see if I got a defective one.

Exynos version at 120hz, a bit over room temperature screen off, warm when in use and hot when taking pictures. My note 10+ and oneplus 7t pro were never this warm. I'm also getting pretty bad battery life.

Note20 Ultra 5G 512GB Unlocked/Sprint
All around quite warm, charging, viewing, hotspotting.

Strange. Having used notes since the first, i must say this is the coolest phone ive had. By cool i mean temp - avg cpu is low 30°cs, multiple runs of back to back antutu only got me to 37°c - with performance varience less than 3%.

It didnt heat up much when charging, editing 108mp files, or 4K/60 recording

Of course this is SD 865+ (N986N South Korea), not exynos like my older notes.

But so is yours. Like Jerry Rigs, may be urs has graphite cooling.. I wonder if some phones (like SK version) have the SD chip with copper cooling = which would be the perfect combo...

Snapdragon HK version here. No heat whatsoever. I am not playing games. The screen sometimes gets just warm when I use extensive tasks (camera, youtube, etc). CPU temperature always below 40C.

UK Exynos990 from official pre-order, so bad in heating and battery life. Warm normal use anything slightly CPU/GPU intensive make the phone as hot as a fry pan.

Note 20 ULTRA 5G 256GB "Exynos" - mine seems cool most of the time. Haven't been able to make it hot even with gaming or using camera.
Seems huge improvement compared with Note 8 in this area.

Wow are your temps still that low? How about when wireless charging? I have the South Korean version too and I hit about 40c when wireless charging, and a lot of times it just sits around 35c when doing normal tasks.
