Hi. I noticed that the left hand part of the screen of the Note 8 (about a third of the screen on the side where you have the menu button, all the way along the left bezel) gets slightly warm with an hour or so of heavy use. I thought it was just my palm warming that side of the device when I'm holding it, until I realized that the same thing happens even when I'm using it on landscape mode. 2/3 of the screen up to the right bezel stays cool.
Anyone else notice this on his device? Is this normal for the note 8 N5100?
Yes with heavy use

Sorry, perhaps I shouldn't have put heavy use there. I'm running stock Android and with just a couple of apps in the background (say 5) the screen starts to get warm already. Is there anything I can do to remedy this?

getting warm for all Quad Core device is normal (up to 40-45 on heavy using) But if u see something more than this take it to service
u can find apps that measure temp of device and battery on play.store
:good:

I have installed Battery and System Tuner Free. The first one gives me battery temperature readings of anywhere from 31-33 degrees Celsius. System Tuner Free gives me readings of 42-51 degrees Celsius. The range happens when I'm using anywhere from 1 to 9 apps at a time.
All devices that are used heavily will really turn warm, that's normal hehe. So better dont use it that much. Let it rest for some time.
How about when you are playing hd games? In my case, Playing need for speed most wanted makes my note 8 hot too. will this damage my unit?
my note 8 get very hot when i play modern combat 4 the temp about 71 degree (measured by system tuner ) and the battery temperture about 37 or more and the left side of the screen becomes very hot and the battery drain quickly is this will harm my device ??

No. If the temperature is out of spec, the system will shut itself down.
Internal resistance in a computer + voltage = heat. And the heavier the usage, the more the heat. This is normal, folks. It would be very magical if the device did not generate heat.

ok thanks a lot for your reply
Yeah, I think playing the more graphics-intensive games really pushes my device to the limit. I switched to Android Tuner from System Tuner because it has a much cleaner UI and I *think* I understand more on it I also get readings of 70 degrees and 36 degrees for CPU and battery respectively while playing Iron Man 3 and Quadropus.
No shutdown so far so maybe that means the device can still take the heat. Thanks a lot for your replies!
Leardsdat and
It's totally normal, see both the CPU and the battery (and screen, if it's brightness is high) is warming your device. And in my understanding Android keeps it's applications on background running unless you kill them with an app or from application managing. So this means your device is processing many things at the same time and it will make it warm.

My Galaxy Nexus often increases its heat to around 42 degrees Celsius (108 fahrenheit) constantly with minimal use (light 2D gaming for about 5 minutes), surfing the app store and playing around with the menus for a 10 minutes. I have installed the battery monitor widget application (free) which tells me everything and gives a timeline of different temperatures the phone reaches.
Constantly the phone is 30 degrees Celsius (86 Fahrenheit) and above, even during minimal use of apps (only running one app at a time, I selected the phone to only use 2G networks and it has no data plan).
This seems very very hot for a phone. My Galaxy S2 doesn't get past 28 degrees celsius (82 fahrenheit) under very heavy use whilst on 3G. My HTC Mozart is the same as the Galaxy, it barely gets above this temperature. Is the Nexus supposed to get this hot?
So far my battery life is set at 17 hours battery life with minimal phone/texting on 2G (literally 2 text messages and 1 phone call per day), 30 minutes of light 2D gaming and zero music or videos being played. There are no programs running in the background and the brightness is set at 40% or below.
EDIT: Even on standby without use for hours the phone has NEVER gotten below 26 degrees celsius (78 fahrenheit) .
I'm hoping someone could share info on the heat of their devices/the normal range of heat that these kinds of devices should be putting out. It sounds interesting that this much heat can actually be created, more elaboration would be better though.
bumping for answers for op.
I noticed a dramatic difference in the temperature from my evo 4g. Some potential causes:
* high stock voyages (there is a great thread in the Dev section about uv kernels)
* when running modaco's brightness patch it got worse for me.
* since it happens with the screen off, it is probably not tht...

What's your ambient temperature?
Absolute temperature doesn't tell us much, what's useful is the delta between device temp and ambient temp.

The room temperature is air conditioned around 18 to 25 degrees celsius (64F to 77F). The phone should not be hitting above this range, especially on standby. It should not reach 40 degrees Celsius whilst texting/app surfing on 2G.
Same issue here.
My Nexus One's battery is at 24C (plugged in, not charging).
And by GNex's battery is at 37C (plugged in, charging)
Okay 37 is fine but 42 is not :/
right now I have flashed a few roms and am browsing tapatalk.. at 34 Celsius. Just applied my undervolts though so we will see

Mine increase more than 42c when using too.
Just bought the phone and mine seems to overheat too much... going to buy a case....
Battery says 46 degrees cel...
also i noticed on galaxy nexus it get too hot around the camera on the back and the earpiece on the front.
noticed the problem mainly when in an area with weak reception. or while charging the phone even with good reception.
its something with the radioROM or hardware.
any suggestions??!!
normal
Its normal! 76F when not in use 90-101 in use 101-120 with charger and using . I called Samsung . My euro gs2, at&t gs2 and my skyrocket all have the same temps remember this is a very thin plastic phone with battery right there behind tiny plastic cover . Think of it like this dose ur computer get hot when u use it?? ? Have u ever even thought bout that? No cause ur not holding it in ur hand .

This is a dual core phone, it is going to run hot because it's a dual core processor with no cooling other than dissipation. It's not a problem unless your phone is actually crashing because of it. I've seen mine get up to 46C during long periods of gaming/charging.
I expect the hardware has been developed to tolerate these temperatures or we'd see a lot more "my phone overheated and now it's a brick" posts or even "my phone exploded into flames" posts. Have only seen a couple of the former and none of the latter.
Running hot after root, rom and maybe 'incorrect charger'
So like others here my GSM version Galaxy Nexus phone is quite hot at the top right corner back and front, near the camera. Only when the screen is on. Battery drops very rapidly too.. like 1% every 30-45 seconds...
This heat is brand new. I recently rooted and romed the device after the recent ICS update cause signal loss when the screen was off. I tried AOKP, various kernals and have now returned to the original backup of android 4.0.2. The heat continues with the screen being on, through all of this. Doing nothing, wifi connected... just on. Screen off no issues. No apps are installed except stock. Default Kernal again.
I also noticed i plugged the phone in with my blackberry playbook charger at the same time as all of this. The specs on that are playbook charger output is 5V @ 1.8A..
I notice a few other people posting about this so want to know if this might be rom related somehow, or if perhaps ive done something to the hardware from the charger. I've tried a spare battery that was not used with the charger at all and the heat continues.
There was no heat at all like this before this last 24 hours so its not 'normal use'. Promise Hope someone has some possible suggestions to try
Mine is at 31 right now.. listening music and xda... if play games it goes to ~35 if I plug it in it gets hotter than 40...

Mind to share? Dial *#0228# to show.
Here is my numbers(indoor usage) :
When idle: 24C to 27C (75F to 82F)
When general browsing etc.: 28C to 32C (84F to 90F)
When playing video or game: 34C to 39C (93F to 102F)
27C-28C idle for me.
28C-34C when just doing general browsing such as reading XDA.
35C-36C after about 5 minutes of light gaming (e.g. Candy Crush Saga)
Running Wicked v4 with included kernel, underclocked to 1674MHz, contained in a Neo Hybrid case.
Above temps while not charging. Charging temps are much higher.

Wow... I average between 75 and 85F (29-35C) under normal use/idle... I've seen up to 105F (40C) under heavy use or after flashing a ROM and the initial setup.
I think those temperature readings are for the battery. If you want to check the real time CPU temperature check out system tuner. Btw, you have to be rooted in order system tuner to access the temp readings.
Yeah i think those are their battery temp readings. My CPU has heated to over 70 degrees under heavy gaming, and averages 40's and 50's under basic usage.

+1 similar results here. Although just noticed the external thermistor reading from *#0228# is similar to cpu temperature but with lower refresh rate. It is on par with my idle temps but doesn't show real time hikes. So here are my external thermistor readings. While browsing on Wifi at room temperature, it is about 38-40 C and under heavy gaming it goes up to 48C (playing Real Racing 3 about 15 min)

If you are on stock rom it should work. Make sure to dial the exact *#0228#. There will be two temperatures on that page. One on top, which is the battery temp. And one on the bottom which is right under 'external thermistor'. I think, external thermistor reading is either the average cpu temperature or a sensor that is very close to cpu.

Yeah i'm not on stock ROM, but my kernel has a CPU temp reader that checks every second, and its currently at 44, under mild usage.
interesting stuff, I'm planning on buying a S4 soon
It makes me somewhat feel better knowing that mine is just normal like everyone else's.
However, this is really a too "hot" a phone for me. so I am dumping this one for something else.
It was fun ride, but it gets uncomfortable when walking with this little "heat radiator" in my pants pocket. For people having cold hands, it might be a feature, but, too bad, it is not for me. I might check out the Galaxy Tab 3 in few months.
Lol I'm running PAC man w/Chronic Kernel, Apex launcher.
Friday on one of the hottest days in Phoenix 116, in my car w/out A/C using I heart radio on my phone. The radio stopped, after a minute I looked down found it had rebooted it. So I went to the home screen where I have system tuner pro widget and the CPU temp was 200°F... oh crap, pulled battery out left it like that till I got home.
Got home the phone was still hot, so I put both the phone and battery in the fridge for 30 min. Installed the battery after retrieving it and the phone and crossed my fingers and made a prayer. Phone booted up and still operates as advertise:thumbup:.

From GT-I9505 Dial *#0228# I only see battery status and "quick start" button, so I used *#0*#, select sensor, select thermistor, "AP" column (= Android Processor Temp). Is that the same thing your looking to compare?
At boot: 31C
Idle: 36C to 37C
After 3min video playback: 45C peak
I am still under the period where I can have this replaced so im asking if these recordings are normal. 49+ deg celsius when was using the quick charger while making some spotify music offline. Around 900mb on wifi. 43+ was when i was playing hearthstone on LTE. Also having trouble reaching 3h screen time with moderate use. Also worth noting that i think this is the processor heating up, not the battery.
Should i have this replaced?
Every mobile processor in the world will heat up on heavy load content, we are not using feature phones anymore, and this is our reality now, smartphones get warm and hot and we need to live with it =]
Also, this is where im at right now after an hour and 10 use at 85% at 41 deg celsius

It isn't too much, the battery is receiving electricity at a faster rate which causes the phone to heat up and then using the phone on top of that produces even more heat. It is also recommended not to use it while it is on the charger (the fast charge ones).
So this is just normal then?
Attached below is a picture of my Hardware activity while playing Power Rangers Legacy Wars which admittedly is a graphically intense games but I'm worried that the temperature of the GPU and or CPU is getting too high. I want to make sure my Note 4 isn't getting too hot here is the picture:
I need somebody's help. The coolest my Note 4 seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius
If you're worried about high temps during games I'd recommend turning the max GPU frequency down. It significantly reduced my temps and I didn't notice a significant difference in gameplay.
Thank you for your response. I have done that and it does not seem to make a difference I'm still getting CPU and GPU temperatures in the high 70s to low 80s

Would you mind posting a screenshot as above with the same overlay? How long are you playing before it gets to this point? Have you adjusted throttling temperatures?
Edit: Saw your other post and wanted to add some troubleshooting. When you open up TWRP and do a file transfer or backup how hot does your phone get? Mine would get pretty hot to the touch, but I don't remember it getting above 80 C.....
The temps you showed in the other thread are definitely not "normal" from my experience with day-to-day use. Did you ever look at the task monitor app I linked to?
Sure I can take another screenshot. How do you want it? I did check out that app and the only thing that I saw was that it seems as though my CPU cores were always running pretty high but I didn't see any applications taking up and unusual amount of processing power. The temperature ranges to about 60 as soon as I open a game for the most part and continues to slowly rise from there. Yes that's about the temperature I get everytime I go into TWRP. I don't even have to be doing anything I'm just open TWRP work and that's about the temperature I get

Sorry, I posted that before I noticed your updated screenshot. I was just curious if limiting the GPU made any difference.
Honestly I'm running out of software suggestions. Do you have some sort of case/screen protector that could be affecting it? How hot us your screen (qualitatively)? I just looked at an old video I made and my phone was 52 C in TWRP, which isn't too far off from yours so it might be fine (as I said my phone screen would get too hot to touch at times during intense games). But if you look at kernel adiutor and see that the CPU rarely drops to the lowest frequency/deep sleep there's probably something wrong (unless your screen is constantly on). You could try a different kernel or governor, or check an app like gsm battery monitor to see if GPS or something us hogging CPU time, but I don't really have any more ideas. (Although I did used to cool off my screen with a wet towel when it got really hot)
Just to confirm: you're running a Verizon note 4 right? (Have to ask)
You've updated the modem to the correct version through Odin?
You're on the proper bootloader?
First of all thank you for your help once again. I don't know how to measure how hot my screen gets I don't have any tools that would allow me to do that I do have a case and screen protector on but it doesn't seem to be any worse than it was before I put them on. Yes I am on the correct bootloader and I do have a Verizon Note 4 running the nseven ROM and I am on the correct modem. I'm willing to do anything at this point. This is the second note 4 I've had with this issue and I just want to be able to use it. I want to be able to play my games and stuff you know. So if there's a literally anything I can do . plus I don't really have money for a replacement

I found this: https://forums.androidcentral.com/s...bout-cpu-temperatures-according-cpu-z-s6.html
Which shows some pretty high temperatures during heavy and normal loads for a G4 and some other forum discussing how their note 4 would reboot due to overheating. Since you're not experiencing that issue I'm not sure you need to worry too much. Your processor should be throttling itself if it's getting to hot to make sure it doesn't get damaged. I'd try to make sure that you limit your gpu to around 300 and then just make sure your CPU isn't overclocked and you will probably be fine. My note 4 would get so hot that I couldn't touch the screen, but it still ran like a champ and never rebooted on me. The only thing that is concerning is that your CPU clock specs aren't sticking, but you'll need to read around for how to fix that since I've never had an issue.
Okay well that makes me feel a whole lot better thank you. According to GSMArena the processor speed of the Note 4 is 2.7 gigahertz and mine is currently running at 2.4 so while it is a little upsetting that I can't bring it down any further, at least I know again according to GSMArena that my processor is not overclocked. Thank you for everything
Hello, I have the S9 for almost a week now and i think its getting hot sometimes with just a normal use (facebook, internet etc. not gaming). Whats the ideal temperature is should have. i think its getting warm on the upper screen and a little on back at camera place. While charging is a little bit warm but i think its normal. Should i send it for a test or getting a bit warm is normal?

Have you looked at the battery or CPU temperature for your phone? I'm wondering this too about my own. I sit at around 85 F (29.4 C) while it is in my pocket. It gets down to 72 F (22.2 C) while on the table. That's about the room's temperature.
Definitely getting warmer during certain use than my S8+ ever did (I remember noticing that it pretty much never got hot) or even my Note 8.
I have an Exynos version though so probably has something to do with how inefficient it is when the cpu ramps up.
Haven't noticed any warming on normal use. When gaming, yes specially pubg. Not too much coc.
SD variant.
Is it about 22,5C CPU temperature when not used, its the same with rooms temperature. after 15 mins of use for example scrolling on FB it reaches 35C both battery and CPU (from AIDA64). Battery also drains fast. Last night 30 mins of scrolling on FB lost 10. Screen brightness is always less than half. and only WiFi and sync are enabled. AOD disabled. Bixby button and bixby home page disabled. While sleeping also battery loses about 8-10%. Yesterday with 15 mins driving with google maps the screen was burning.

Honestly, i would recommend it. Even the plus. For me tho carrying more than one phone for work and stuff it got old having the s8+. But for the s9, man the stereo speakers sound great. Much better than last yr but of course they werent stereo so diff is noticeable. As for pubg, i really have messed with resolution and looks great i think im on fhd. While playing tho the s9 does warm up, havent checked exact temp but its noticeable. Cant say if it does the same on the s9+. Hope someone can confirm.
I look at it this way, like having a macbook air for gaming vs a macbook pro, the air will make more noise and warm up vs the pro.
