Galaxy s8 Gets Hot - Samsung Galaxy S8 Questions and Answers

Hi i bought the device two days ago and whenever i use it (i start opening Facebook, instagram, WhatsApp and other apps) it gets Pretty warm in the right side or the screen and behind. The CPU reaches 50 degrees and sometimes 55 and the worries me. What should i do? Is it normal or should i return it? I previously had an Honor 7 and it reaches the same temps but it doesnt feel that warm at the touch, it Just gets warm in the bottom left corner.
the temp while i'm typing is 41C, outside its 33degrees C and inside(where i am now) its 24degrees.

I do not believe this is normal whatsoever. My S8+ has been one of the coolest-running Samsung phones I have ever owned. You might want to return/exchange it if that is possible.
I have not used/tested with any apps to determine actual Temps but it never gets hot. It gets warmer but not very hot (like my S7 Edge did) when using Gear VR.
Have you done the simple things like closing all apps & rebooting? Clearing cache, etc? Maybe some app is "stuck."

Yes i tried everything

After how long of using these apps does it get warm, right away or after 5-10 minutes?

I would say 5mins. Now it gets maximum 48 degrees in the CPU but i feel the screen and the body Pretty warm... Maybe it's me... I don't know. Feel free ti suggest me what should i do

it is absolutely not normal
my first device share the same issue with your's
well i ask for a exchange, the new unit just go to 45 when running games, most of time it wouldn't even reach 40 degrees
but
new device came with new problems, red tints, home button problem
it's up to you
ask for replacement until you'er satisfy with it

I would get an exchange(Yeah right the real me would hold on to it until it melted because i'm lazy). So far this is the coolest smart device I have ever owned. Even when playing intense 3d games and emulators it only warms up a little.

Thanks Guys! I'm going to return it on Monday.

If you're constantly scrolling and opening posts the phone will get warm, Facebook isn't exactly a battery friendly app, but if you're stuck at a post and reading it for a while it shouldn't get warm, it really depends how you use the phone. I can get my phone warm using twitter too. My friends z5 with the sd810 gets toasty.

Mate. The CPU throttles when it reaches 80C. What are you worrying about?
I advise reading your manual, which specifically tells you that the device will heat up with use and the heatpipe is located on the top right section of the phone x)
The reason why it may feel hotter than your previous (?) phone is because the metal rim (and whole body) acts as a heat spreader and the heatpipe connects to it with a thermal pad.

Trueee ?

Cpu temps keeps spiking up and down on any device that actually has a cpu.
What you need to look for is battery temp and not cpu temps. I consider battery temps a more steady measure of over heating rather than cpu as they dont spike.
Eitherways heavy bad background apps will make any device hot. Now if your just browsing on chrome with no background apps and your device temp ( battery temp ) is around 40c in a 20c room thats when ill be worried and exchange the device.
But hey thats just me
Gd luck !

i also have the feeling that the phone get's warm. G950FD
i received yesterday, and im comparison to my OP2 this one feels all time warm.
just looked at the battery temp and it's @ 35,8°C... i will look out for the temp, and see if it changes

Is your Nexus 10 getting really hot?

When gaming, it gets so hot that it makes me think "this should definitely not be this hot", I would categorize it as "an unusual amount of heat". It makes me afraid I'm going to melt something on the inside haha so I give it a break. I know it's hard to describe temperature over the internet but is yours getting uncomfortably hot?
Near the top/topleft in landscape
Mine sometimes gets on the warm side, but the Nexus 10 has safeguards to prevent "dangerous" temps (your CPU clock will downclock in increments of 100MHz until the CPU gets cooler, and then spike back up to 1.7GHz; lowest I've seen it go was 800MHz).
Download Cooltool at play store and set up what you want to show as a floating widget. This is how I monitor my cpu, batt temp, ram, wifi strength etc. This way you can be more accurate in determining wether your device is too hot and if you should be worried.

Hey thanks a lot for that! but uhh how hot is too hot for the battery?
Mine gets really damn hot as well near the removable cover. I really pondered removing the cover and back and seeing if I can make vents in the back, with a screen, then I can remove that removable cover while gaming. It's most noticeable during Need for Speed most wanted.

It doesn't really bother me, per say, but I'm just worried that its going to mess it up, but at any rate good to know it's "normal"
Normal: 70 d F
TOO HOT: 95 d F
Mine does that too. I have noticed that the case is starting to warp where the heat is most concentrated... Just to the left side by the power button. Between the power button and the camera. Almost like some glue came off and the casing is separating...

That's not good
I was using mines for google talk video chat and it got really hot. I checked the temps and it was at 91F.
Ok I did a test again and it went up to 105F. All this just by video chatting. Thats not normal!
Mines getting hot too just an hour of browsing the web and its extremely warm.

Why do you think that? It's perfectly normal for a chipset like this.
Its not just the top part thats hot like it should be. By holding it with my hands on the side you can feel the heat.

If you blast through the battery in a few hours with 3D gaming or the like the battery will get warm, too (40-50°C).
it was only like 20 minutes. I'm not saying the device getting warm isnt normal. I know that it is. However the first device i had did not get as hot as this.
The N10 is thin and very powerful so heat might be more noticeable. As long as it's "only" getting warm and not slowing down/stuttering in this state, there's nothing to worry about.
lol thats kinda the problem. the video keeps stuttering and freezing and so does the game....
everyone should be undervolting the nexus 10
this device can't even run at stock speeds for extended lengths of time without throttling due to high temperature...
it's easy to test, just run StabilityTest (search google play) and run the Classic Test... you'll eventually see your CPU throttle down from 1700MHz (mine goes down to 1400MHz every so often... i'd probably go down even more if i hadn't undervolted it)
therefore, undervolting it will help it run at stock speeds for longer
I noticed mine heating up for the first time. Don't play many games at the moment. Heated up quite a bit between camera and buttons just like others have mentioned. I was playing ingress when I first noticed. Also when I was just using browser to the ingress/Intel page. I was thinking it had to do with GPS but after reading other comments I guess CPU was working hard refreshing page.

[Q] Overheating Problems [franco kernel | cm 10.1]

After having my phone for around a month, I (yesterday) decided to flip the switch and flashed myself cm10.1 and the latest franco kernel. Just now, I reached to pick up my phone (after letting it idle for around an hour and a half in my pocket), and burned my fingers. The thing is running at 46.5c when the highest it used to get for me was maybe 40-42 (watching a movie, or charging).
What do you guys think the cause is, and my best way for fixing (I dont want to go back to stock, but I will if I have to).
Thanks,

your device isnt overheating nor did it burn your fingers. human body temp is 37C, and it was sitting in your pocket at that temp, insulated, keeping warm. 46.5C will not burn you, ever. it could feel warm because the heat is escaping from the glass back to cool off. thats what its supposed to do. you have a quad core device, it WILL get warm.

is this a serious statement or sarcasm? lol.
while charging the battery can get hot, and the device can get really warm, especially if its being used at the slightest bit. besides, what is overheated, i mean what temp does it reach, battery and cpu?

my phone is currently charging and I'm posting this via phone.. so this is in no way sarcasm . it's showing battery temperature as 39 degree Celsius ( checked through *#*#4636#*#*) .. my fingers can feel the heat while I type this... though the heat is not too high but it's not negligible also.

think about this.. your body is 37C. 39C is a bump warmer. since your fingers are extremeties, they will be slightly cooler than the rest of your body. since they are a little cooler, your phone will feel warmer. but in reality, your battery temp is just normal, even relatively cool for being on the charger and being used.

Okay, I didn't mean literally 'burn', you're right. My point was that I picked it up and was shocked (figuratively ) by how hot it was.
Again, for the last entire month my phone (on stock) has never reached near this temperature before, even when It was actively running.
[Oh and jacket pocket, it wasnt on me. My point was that it was in a cool, dry, place not charging, and I wasnt using it].

Okay, so saying that makes me stop worrying its going to blow up (happened to my friend's moto milestone back in the day), but it's still a new occurrence to me, which cooincidentally happened right after a changed both my rom and my kernel from stock.
The office aircon is a breezy 24c no matter what day it is .
I was leaning more towards this questions, that I gathered from when i glossed over the two respective threads, but dont understand well enough to decide or check if they're relevant:
-could it be that the rom or the kernel overclocked my phone and thats why its running hotter?
-maybe theres a wake-lock (or partial lock or whatever its called), that had my phone on though it was being left alone?
-did the kernel mess with the radio so now it keeps jumping signals?
-was there an option for 'testicular irradiation' that I accidentally enabled?
Not even sure if these are the right questions to be asking. Definitely not sure what to do about it even if they are...

there could be 1000s of reasons that your device is running a little warmer today, really. it could all just be random too. as long as the battery stays below 55-60C(60C is the battery temp safety shutdown) and the cpu below 80C(95-100C is the cpu safety shutdown). you wont see those high battery or cpu temps unless your really pushing your device(cpu) or watching flash movies/playing intensive games while plugged in(battery). there are safety protocols set in your phone in case it really does overheat.

um, you run it at whatever speed you want. default, it boots up at 1026mhz, with all 4 core set as minimum, and thats recent. before that, it booted up 1458mhz hotplugging, which is still slightly underclocked. just because you have a choice of raising the cpu speed to 1836mhz, doesnt mean that is the kernel default. you should learn about what youre talking about first, before you say something silly.

[Q] LG G2 Operating Temperatures

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.
I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.
-LG G2
I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

The case I had been using with the RAZR was a TPU hybrid. I also went to a skin because of the heat. I don't think I cando that with this phone. I'm too clumsy.

I was actually looking at getting the dual pro. Thanks for the feedback. Exactly the type I'm looking for.
Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out. Loving this second one

Does anybody know if we can track manufacture/release date using the serial numbers?
I am using this case full time: http://goo.gl/0u05G5
I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

yeah, especially while gaming.. and it's not the battery drain that concerns me, the heat is ridiculous for long term gaming..
and slapping a case would be good for your hand but not for your phone
plus there's not one manufacturer that make cases for heavy gaming yet..
i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

One thing I've noticed from people's screenshots is that the screen doesn't use that much battery. My RAZR would sometimes draw 46%. I'm sure that also contributed to the heat. smh.

yeah, especially while gaming.. and it's not the battery drain that concerns me, the heat is ridiculous for long term gaming..
and slapping a case would be good for your hand but not for your phone
plus there's not one manufacturer that make cases for heavy gaming yet..
i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

lol, I've actually thought about making a case like that, then I realized if there was a way to burn myself, I'd find it.

I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.
If you'd like to give input shoot me a pm and we can discuss it further.
OnT: I very rarely pass 24c on mine, then again I never game on my phone either. Highest I've hit was 42c during some testing.

Are you guys talking about battery temps or cpu temps?
Get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.

Is overheating an issue when wifi tethering? I want to use this thing for desktop PC games and downloads; does it overheat after hours and hours of intense wifi hotspot use?

I have used it for a couple hours and it gets warm. Not warm enough for me to worry about checking the temperature.

Thanks for your feedback. Would you say it was with heavy usage?
I have made the tests , and i get 72 °C after 1:20 secs running the standard test. About 35 °C in idle,and about 50-55 °C when i am using the phone for facebook,browser,youtube. Is this ok? (These are Cpu Temps).

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?
Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?

z5 compact general operating cpu temperature

hello all.. I just wanted to understand how z5 compact cpu Temps are under normal usage (basic phone usage messaging, youtube video, basic camera usage, browsing and reading articles).. for example my oneplus one running on snapdragon 801 typically hovers between 33-38 for majority of the tasks.. I understand no phone is the same.. different people have different experiences...Through this thread I would like draw some patterns and conclusions.. thanks!
Just installed a cpu temperature monitoring app to check.(cpu temperature by mooncakes from playstore)
From what I can see (if it shows the correct sensor) it hovers between 28 - 33.
Using a "regular" Z5, though.
While browsing/messaging/youtube for prolonged periods I am usually at around 35-40c.
Gaming with 2d usually stays at around 40c and 3d is at around 50c.
Installing and updating apps usually generates most heat with temps of around 50c+ but fortunately its not something that happens often.

Maybe u could add which app you use, I edited my post too.
Also, I think while shooting 4k video and using the AR effects for prolonged time the temp wil go above 50°c (I'll have to test) but the sd810 probably handles more.
At my old Z running a snapdragon s4 pro shutdown temperatures are around 78°c or so.
thanks guyz.. again.. just to clarify.. we can exclude the extreme cases.. like shooting 4k and prolonged gaming.. these are known to stress the cpu.. I am curious to understand how bad it is during normal usage.. hopefully this will allow others to make informed decisions.. I have mine coming tomorrow!

Well, under normal conditions nothing to worry about. (in my opinion not even under heavy load, Z5 is supplied with a dual heatpipe - but that you'll probably already noticed lol)

I'm using the Cputemp app which has a cool option that adds the cpu temperature to the header of the phone (where the time and battery life reside) so the temperature is constantly under check.
I'll add also that battery temperature is usually at around 30-35c and if you're doing something heavy for a long while it will rise to 40-43c

What **** are you talking? It has, for gods sake.
Premium has dual heat pipes as rest has only single i guess.
My temps are between +17 - +38 last 5 days (no gaming)
Idle temp at night usually +20 or little bit under.
Web browsing get temp usually up to +35

Don't be like that
guyz.. easy.. let's keep the discussion civil... its okay... if a person is right or wrong.. there is absolutely no need for cursing.. I went through https://www.ifixit.com/Teardown/Sony+Xperia+Z5C+Teardown/53206 and there is no sign of it.. you can look at z5 or z5p on the other hand and you'll find it.
check out step 12 through 14.. https://www.ifixit.com/Teardown/Sony+Xperia+Z5+Teardown/52300.. this one uses it.
I already posted it in a an thread, but here it seems more relevant.
I made a small video showing my Xperia z5 compact overheating.
Just with browsing the CPU can reach temperatures of 50 - 60° in 7 minutes.
This happens while browzing at other sites too. CPU throttles bit by bit and it gets really warm.
This makes the back of the phone very very uncomfortable to hold and i can't imaging how hot it will get in the summer or under the sun.
Can you please give me a feedback on that because I am thinking of returning it.
There is something wrong with the cpu temp app that you are using..I just tested two apps simultaneously on my oneplus one...The app you used reported 46C while the "cooler master" app reported 33.3c attached is the screenshot!
There is no way my phone was at 46 because..the phone pretty cool..So I suspect the app is not reporting it right...not sure where it's getting the info from.
https://www.dropbox.com/s/3iq8arqy5fcupex/Screenshot_2015-12-21-14-25-10.png?dl=0
Okay.....I performed extensive testing in the past two days regarding the temps to understand the behavior....Here are the details..
I used my old oneplusone and z5 compact to compare 1. perceived heat (based on touching the device) and 2. actual temp readings from the app devcheck pro.
Regarding temp readings, I monitored both CPU as well as battery temps. I generally felt, the "perceived heat" comes into play only once battery heats up as this lines up along the back of the phone.
Test performed: Used flipboard and news republic apps for 5-6minutes. Then opened chrome dev browser app and loaded "cricinfo.com" website. This web-page is flash intensive and has tons of content. I kept repeatedly navigating through the webpages and accessing links. The idea was to perform intensive web-browsing.
Note that both phones had TPU cases on them.
Here are my findings:
-Both the phone's CPUs start off at 37-40c and gradually hit 55-65c. Interestingly, I noticed that oneplus one at times hit almost 73-75c!! whereas z5c never hit this limit (perhaps due to thermal throttling???).
-The battery temps steadily rose from 27c to 38-40c.
Attached is a screenshot for your reference.
-On both phones, the temps rose almost around the same time (about 7-10mins into the test). I felt at some-point z5c was being throttled to maintain temp thresholds. However, I did not notice any "visible" performance drops.
The key thing to note: The back of the oneplus one was slightly warm. Whereas z5c was pretty warm (although not uncomfortable). I think this is exactly where the user gets worried, thinking the phone is overheating. The problem is the glass back as opposed to the padded material of the oneplus one. The glass surface of z5c almost immediately starts conducting heat and quickly heats up.
After letting the phones cool, almost within 10minutes, both the phone temps dropped pretty quickly.

Any way to disable the automatic over heat screen dimming?

Sorry but if it's overheating then it's a safety feature.
I'm sure you wouldn't prefer to be playing whilst you're phone is on fire.
I'm short, no it cannot be disabled, which I'm glad of as people would just point their finger at OnePlus.
*removes screen overheat dimming"
after 20 minutes of heavy gaming screen dies
*blames oneplus saying very bad phone bad quality etc.*
been there, seen that. to this day many indian users remove thermal configs on their oneplus/xiaomi devices and eventually ends up with dead batteries, ghosted screen, hell some just burn their phones (x3 nfc)
Cool the phone. A fan on it and/or a damp microfiber cloth. Avoid overheating the device.
It's possible for hysterious to cause the thermal protection to fail to adequately protect the device especially in direct sunlight.
The display's thousands of semiconductors are vulnerable to thermal damage, not just the chipsets.

Yep was thinking this too.
Slap a nice big heat sync on the back of the phone.
Problem is the battery is still going to take a massive hit every time anyway.. so you can't win really

Meh, yeah pretty much born to lose
The problem is the long game jerk off sessions on a micro laptop with very limited heat dissipation.
Limit to 5 or 10 minutes or use a gaming PC.

Turn down the brightness...
its not like i leave it dim when it automatically dims., i raise the brightness right away and do this until im done with my gaming session. Phone doesnt catch fire. Thanks for the thermal tip.

It's getting around a 100F ambient here, I use a damp microfiber cloth plus fan when charging and otherwise as needed.
I just watch the battery temp as the chipset runs cool (>120F) for browsing.

That's insane... Have you under locked or played about with CPU speeds? They don't always stick but may help.
I've seen a difference.
Are you using a case on your phone?
It'd be nice if a cooling vent was possible so we could point a solution at it, almost like a latch then have a pass through fan.
Or even plug in and stop using the lithium battery, that should eliminate a bunch of heat.

A stock N10+ snap running on Pie, brightness 30-40%, power setting: optimized, it's in a Zizo Bolt case. Optimized; no cloud storage, wifi, Google play Services, Playstore are normally disabled, and no social media apps. When I first got it it was a hot running power hog... a real menace.
At >95-98F if streaming vids* I need to cool it or give it a rest by browsing after 20-30 minutes. At 100F ambient that's getting near the 102F limit I try to stay below on the battery for best lifespan. That's what's limiting me, not so much the cpu core temp.
It's a clean running machine that's gorgeous, and gets good SOT. Samsung has given me zero incentive to upgrade it... so I bought a second new one about a year and a half ago.
*streaming vids uses almost twice the power as just surfing on the browser. Watching downloaded vids uses less as surfing.

It's already 91F here, the only reason it's not hotter yet was it's a bit overcast. That's burning off, no rain forecast for the next week, just heat.
I never use the power saving mode as it's a pain.
Oddly using peak cpu performance doesn't really add more speed than in the optimized mode.
Using max resolution you take about a 4-6% hit per hour. Even with 20/10 vision the difference is hard or near impossible to spot, mostly pointless to do.
Without a case the N10+ is hard to handle and would get destroyed. Not sure how much of a difference in heat dissipation no case makes as I never tested it. Not worth the risk.
The only bad thing with a case is spotting a failed swelling battery is hidden. Had that happen 2 years ago. Was very lucky the display wasn't damaged. Normally I take the case off every 2-3 months for cleaning as it attaches very little dust and dirt.
Always watch for changes in battery capacity and fast charging performance. If fast charging fails to engage or doesn't stay engaged within its normal temperature and charge % ranges it maybe a battery failure in progress. Batteries can fail at any time but is more likely to happen once a Li is degraded (80% or less of its original capacity).
This current Li has been hovering around 80-84% of it's original capacity for 6 months now. It's a little over 2 years old... I need to change it out soon. Lol, it's outlasted the OEM battery by over 6 months In all fairness though when I first got the phone it was a power hungry hog, took a few months to figure out how to tone it down. Another reason you want to always optimize a new Samsung; battery lifespan, not just for SOT/heat/performance.

Yea defo don't use qhd it's pointless..
Also wouldn't use power saver, I meant actually underclocking in Franco kernel
manager.
I knock them down a few notches, definitely helps.
Also with heat your phone will charge a tonne slower.. first step is 37c then 39 then 40 and so on...
Under 37c and you're getting the full 80 watts.
I think a case with some space In it would help with heat dissipation..
Android 12 also seemed to be much more efficient than 13, I've contemplated going back again and have done a few times.
Certainly shouldn't have to but needs must.

I'm still running on 9 and 10. Pie seems to run the best and is more functional. 10 has some nice tricks but has many dozens of new system apps for the UI. Oddly my disable list is nearly identical for both phones right now. That may change as I play with it more... but I really like Pie.
No plans to upgrade either. No malware on this phone (Pie) in over 3 years so it's relatively secure as configured/used.

The Snapdragon variants are notoriously hard to root. They also have a good vapor phase heatpipe on the SOC.
Not worth it as they run well now
