Heat

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 8 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.

Oh not again. I was just about to ask about this, as my note 7 heats up as well but it hasn't exploded yet. When does yours heat up gaming or just casual use?

What was the ambient temperature of your environment of the time of use? Just wondering.

I've only had the phone get really warm to touch once, when using podcast, phone and navigation in the car. Around 68 degrees ambient. Nothing too unusual. This battery is much smaller and better tested. Though even my Note 7 never got dangerously hot.

I have been using my Note 8 heavy for 3 days now. With the brightness turned up to about 80% and my phone has not even gotten warm.

I drive a lot, in the direct sun and while using GPS and streaming music to the car. Every phone I've ever had has shut down on me at least once, with the iPhone shutting down as well.
Internal temps are usually 60-70°c at that point, so I honestly don't think the Note 8 will be any different.
I'm genuinely excited to see how it fairs, with the larger screen and dual glass body.

I had my Hotspot on all night so I could upload files from my pc...phone was in its case and it was still cool to the touch in the morning...

Maybe I have an older wireless charger, but my phone heats up to 40C while charging and only running Sidesync (wireless). It's the Ravpower wireless charger (not fast charging). This only happened once, and now I'm unplugging the cable to the charging stand after it reaches 100%....may need the ones with the built in fans.

mine gets really hot when watching 4K HDR content on youtube with max brightness... I have to switch hands from time to time haha

I was in my backyard yesterday reading on mine, it was about 90 degrees out. I didn't notice outside but when I came in my phone was hot.
I won't lie, I was concerned and sat it on a table away from me.

Exynos Model here.
Mine gets hot when I watch 4k Youtube videos.
I also noticed that it gets mildly warm when using spotify.
Other than that, it runs cool.

I was recording right in the sun for about 10 minutes I had it set up in 4k, got a message saying that the phone is too hot couldn't use the camera until it cool down.

Never heats! Only a little warm at times

Barely feel any heat even with a long gaming session.

Might be exynos related my snapdragon barely gets warm even after a long periods of demanding games. This is the first phone I've ever used that doesn't even get warm my exynos Note 5 only last a minute or two before it gets pretty warm and thermal throttle kicks on my framerate in games drop.

My Exynos N8 gets warmer in general use than my Snapdragon Xperia XZ. Warm but never hot.

After 5 months of use, my exynos 950F 128 GB only gets a little warm, I have even tried to make it hot, using it heavily, but, no, just a little warm, even cooler than other devices I have had

My N950F Exynos Note8 barely if ever gets warm. Only time I have felt it get warm was when using Googleaps Navigation while the phone sat in direct sunlight in the car dashboard.

Mine is exynos and it gets warm when i play world war heroes with full detail configuration, performance mode on and charging the phone at same time.

Despite living in a hot and very humid environment. I found that my N950N has been able to keep pretty cool even when in it's Spigen Tough Armor.

That is perfectly normal for your device get warm if you are playing graphics intensive games and while your device is charging.

was having some weird issues with heating on 8.0 but now on 8.1 it runs warm as you expect after playing for a some time

Heating while charging
My phone has normal temperatures throughout. Only while charging, it gets hot to around 43 degrees. The max I saw is 46 degrees. The charger shuts off or cuts off the rapid charging without any warning sometimes, as I can see the last full charged time changing on the battery page. This is due to the high temperatures. I have read in the posts online that these temperatures are pretty normal. Does anyone else have similar issue/phenomenon?

I'm recently noticing that my phone gets pretty warm even by casually using the phone for instagram or chatting (basically just having the phone screen on for at least 15-20 minutes). Watching videos will always make it pretty warm now (I don't know exact temperatures, but it feels very warm that I can't keep my skin on the phone for very long without feeling uncomfortable). I used to be able to watch videos while charging the phone as well without the phone significantly getting overheated, but now it even warns me with a notification that it's getting overheated and I should stop. I have a screen protector on both the front and back, and it starts coming off the phone solely because of the overheating.
Not sure when did all this start, but not more than a month or two. Im on Pie and the latest security update. Haven't reset my phone in quite a while.
**EDIT:** Adaptive Battery and Adaptive Brightness was turned off as advised for other issues in the forum, but turning them both back on not only did reduce the heat, but the battery drainage is way less now.

yes its there
heating issue is still there ..

My P20 Pro gets VERY warm even without gaming under heavy screen usage. Lightroom, google photos, email, hangouts... I then put it in my pants pocket and could feel the heat noticeably till it cooled down.

My p20 pro is still pretty cold as it hasn't arrived yet

I've been surprised at the lack of heat!

Weird. Mine is fine. Something sucking up cpu time in the background maybe?

Mine gets quite warm even after light use (especially in the upper left corner).
Does the same happen to you? Is it normal?

Hi, same thing happens to me, albeit after a bit longer/more demanding use.
I've noticed when playing PUBG only, after the latest update that gives the game suite and some sec updates i think, the phone becomes warm, and then the heat from the battery/cpu interferes with the touchscreen and exactly where my finger is to move in pubg, its the warmest.
Thus it stops registering my finger and i quit moving in the game, wouldn't notice this on daily use of course, but i think it is a huge issue. Not because i died multiple times due to that in the game, but as it is a new and kindof premium phone, this shouldn't happen at all and was working perfectly for 2 months before that.
I've even installed an app to measure the temperature and it goes up to about 49 degrees celsius.
Any ideas?

Don't have any issue. Was using iPhone 6 and it was literally burning while am playing any game.
This device is far from getting warm compared to iPhone 6 and 7.

I'd say the P20 Pro is average when it comes to heat during use. It will never get uncomfortably hot, but can get fairly warm when gaming.

Phone has not felt even the slightest bit warm to the touch no matter what I'm doing so far. Like literally stone cold 24/7.

Mine gets hot after playing 3D games. The heat is mostly at the top of the device around the camera area.
Fine in normal use though.

I've played a couple games for a while and it seems to only heat up on graphically intensive, but I mean that's expected. I played the stranger things game for about an hour and it didn't warm up at all. I switched to shadowgun legends, maxed the settings out, and it started getting hot within like 5 minutes. As Joe explained, it gets hot near the camera, but it isn't too bad and it cools down really fast, literally in a minute or so after closing the game.

Yeah, agree with all of the above. I should clarify the game I was playing was Honkai 3rd Impact on max settings which is fairly graphically intensive.

At what temperature does your OP6 hover at.
I don't play games.
As per cpu-z, mine stays between 30.5 to 39 degree Celsius.
(The temp here in Punjab, India reaches 47).
It feels like warmish after I installed Apple music app yesterday.
Before that didn't feel any warmth.
Thanks.

I tested cpu-z for you and got very similar temperatures. I was at around 28°c after turning my phone on. It went to around 31°c when scrolling through twitter and listening to Spotify. And after playing showdowgun legends for a few minutes it got up to 38°c.

I'm no expert, but since we have similar temperatures, I'd assume it's completely normal.

Yup, same temps here. Nothing to worry about.

Hi..
Could test with the cpu-z app as to what temperature your set reaches when it's the warmest.
Mine has reached almost 39 degrees Celsius when using for everything other than games, for an extended period.
Sometimes though.
Usually it stays around 31 to 35 degrees Celsius on Cpu-z ( its peak summer time here in India, with daytime temperature always above 40).
Above what temperature should one get worried?
Cheers

you "worry" above 80 degrees Celcius, but I dont like it to get much higher than body temp.
I does cool off fast, But it can get really warm sitting in the sun.
I leave mine in a holder on my dash while I drive, playing pandora via bluetooth, and it can get pretty hot.

A few minutes of use, Pandora playing through internal speaker. Heavy JavaScript use on web browser.
It should be noted that my OP6 is Rooted and DeBloated.

Still not clear on one thing.
As to how hot is worrisome?
I spent a full hour browsing Chrome, in a car in a parking lot with no AC on and outside temp hovering at 38-39 degree centigrade,
and my device's battery temp (as on cpu-z app) went to about 41.2 degree centigrade.
I turned the AC on and within no time fell down to 34 centigrade.
Is that normal behaviour?

Of course it's normal behavior if your surrounding temperature is that high

Did you notice, the manual says:
Only operate your phone between 0-35°C temperature and 35-85% humidity

The maximum ambient charging temperature of the equipment declared by manufacturer is 25°C.

Good luck with that in the summer!

I'm finding the screen does get noticeably warm to the touch at the top area near the SoC, just from normal use (such as using Chrome etc). Battery temp rises to about 35 degrees.
A little concerning I'd say.

Another disadvantage of glass back (beside dirt, fingerprints, fragility)

Sorry, no heat at all. Tried with COD, Pubg, Real Racing, Cyber Hunter etc.

I think this phone warms more than others in its price range (though I never played games on a phone).
Nothing to worry about but with regular use it heats up.

Can't agree.
Even when using navigation or playing a game my device doesn't get warm at all.

You have bad apps or faulty device. Mine is the most cold phone I have ever had. My phone is always cold to the touch unless I play heavy games and even when playing heavy games at 60fps it's only slightly warm and still perfectly comfortable to hold even when gaming for over 1 hour.

Using for a month now, Heats up to 43 degrees sometimes while charging. Otherwise, it's cool even while playing games like pubg for a long time.

by far the coolest phone (literally) I've ever had. Even with stress tests the phone gets barely warm. I tried throttle tests too. even after very long periods of time there's no thermal throttle at all. this might be one of the best qualities of this phone

Today I realized that the Redmi Note 9 Pro is a cooling expert. It was 29 degrees C outside and I walked on the streets with my phone in my front left pocket of my jeans. I definitely felt my left leg freezing. That much cooling from a phone? Is that possible? I mean, I felt it's possible... Cool.!
Great job xiaomi, intentionally or not.

that's what you get after putting the phone in the freezer for a couple of hours and then placing it on your pants, you don't really need to use a phone for that..

Great phone, No heating after playing Pubg for long time.
Best devices from all of my others phone.
