[Q] Does Galaxy Note 8 suffers from heat problems ?

Hello to all Galaxy Note 8 owners',
I've read most of the review online, but only a few stated about the heat issue on this device.
So, my question is does your phablet overheat ?

Uh... no? This is about the coolest running tablet on the market. Also, I have read every single piece of literature and commentary on the internet about the Note 8, and not once has heat been mentioned. Where, exactly, are you reading this?

Mine runs perfectly. No heat issues whatsoever.

I haven't noticed much heat or warmth at all, much less heat problems. I'm not a tablet gamer. But I do watch video, and download files (sometimes big ones and using Advanced Download Manager). And not heat issues.

Mine gets pretty warm on the lower lefthand side of the back plastic. Probably 10 degrees over ambient temp.
This is consistent with other devices that run at relatively high clock, or my phone if the wimax antenna is on - I'm not seeing it as a problem.

The only time I have felt any excessive heat, is when I was watching Netflix and charging at the same time. I use this tablet very heavily and have not noticed any heat issues!

Haven't read anything about heat issues on the Note 8 myself, nor have I observed any serious heat issues on mine. It'll get warm with intense use, but no worse than other tablets or phones in my collection.

Correction, only one on the net.
This is the link "hxxp://pocketnow.com/2013/04/09/galaxy-note-8-review"
Quoted here the relevant paragraph
-- "Other than that, the performance on the Note 8.0, even during graphic-intensive games, was exceptionally smooth. Though, after several minutes of intense gaming with the display brightness turned up, the device did tend to heat up a bit, but not to the extent the device was uncomfortable to hold." --
I'm asking because I've read heat problems on Galaxy Note II and Galaxy S3
Thanks for all your reply. It's good to hear that this one does not suffer from heat issues. If it is, I'll have to switch to Asus Fonepad, man.. that thing is half the price than Note 8

Device warming up is not the same as a heat problem. My S3 and the Note 8 will both get warm with heavy use, but so will everything else. You have to have realistic expectations on a device that only has passive cooling. Heat is a problem if it causes the device to crash or otherwise misbehave.

Used mine to play a game with 3D graphics for an hour or two and it was only slightly warm. Tablet was sitting on my pillow.

Echoing this statement. My Note 8 gets noticeably warm on the left side even on lower loads. It's never become hot enough to be an issue though.

Ditto...
My charger does get warmer than my G Note 10.1 and my G S3...

Mine is just like any other high end tablet. Stays cool but gets slightly warm warm when used heavily. I have the 3G version.

overheating? Try meltdown!
A few months ago, my wife and I visited the local AT&T store and picked up a Galaxy S4 and a Galaxy Note 8.0.
While my SG4 is working beautifully, the Note 8 is unusable, even after having it sent in for repairs (the problem persists as if it was never repaired).
Basically, it has a glitch that I've seen before on PCs that have a heat-damaged GPU. When the system is booted, it displays a graphically garbled mess and will not achieve full boot.
We have reloaded it, to no avail, and as I say, it's already been sent in for repairs yet it came back to us as if nothing had been done to it at all. It worked intermittently, as i had before the repair, so my wife tried to make due because we couldn't take time off from work to go back to AT&T in the last few weeks since we received our Note 8 back from Samsung (or whoever they farmed out the repair to). In the last few days of my wife using it, it's gone from intermittent to full-blown unusable. Now, about 15 to 20 seconds into the boot sequence, the GPU overheat glitch rears its head. There's no way now to get to the desktop to attempt another reload... but that wouldn't help anyway. When we last took the unit in for repairs, I reset the device to factory defaults at the request of the AT&T rep that was assisting us. Within 2 minutes after booting back up, the system was nearly unusable.
It was a rockin' little tablet... for about 4 days until it started overheating. I'm figuring it's likely a manufacturing flaw, based on the testimony of others that for the most part claim little or no heat issues.
Now, I'm not sure what we can do to rectify this. I hope we're not stuck with what amounts to a brick.
FYI / background-info: I've been a computer user for 31 years, and worked professionally in IT for the last 15 years. Embedded hardware hacking and embedded systems development are a few of my many technical hobbies. To say the least, I've been very thorough in my examination of this problem, and have an immense amount of experience with a large variety of hardware, which is why I recognize the problem to be related to overheating damage to the GPU -- I've seen it plenty of times before... the summer heat where I live will kill a GPU if it's fans aren't cleaned monthly, due to the amount of dust that blows in from the plains states immediately to our west.

i have GT-N5100
the unit so warm (not overheat) if i played some 3D games for a few times.
left side of the note.
and maybe i suggesting you not playing much games or heavy games with this Note 8.0
i don't know about the other handheld, but note 8.0 almost suck my battery 1minutes : 1% just for play LINE I Love Coffee or any light-weight games.
BUT, if you do for work (write on S-Note or drawing or adjust some shortcut and setting) it'll be so damn long lasting battery, but once you play (at least) 1 game, you'll see the battery drain so much.
don't know how to fix this (even i already turn on the Power Saving and turn off another function except vibrate, and screen rotation, also wifi...because i use battery program..that program indicate use Mobile Data/3G more drain than Wifi)

That's how the first Note 8 that I was shipped was (my post about it is somewhere) it was roasting when it arrived and oddly the battery showed it as fully charged. Screen was a complete disaster, reset it and it was fine for a few days then started acting up with the heat and screen issue. I only had had it a week so I just asked for an exchange (at first they wanted me to go through the warranty to fix or replace it ha! No). Got this new one and have had no issues (except the wifi which I finally seem to have working but that's whole other thing), like others said it just gets a little warm on the left side but nothing like that old unit and nothing horribly burning type of noticeable.

Mine said last night that it had to close down programs and I could only use the phone because it was overheating. It was cool to the touch every where and battery monitor said the temp was 30*C or 86*F. So does it over heat not too the ftouch as it always seems cool when held, But?????

Tmobile version overheating

I've been reading the other thread about overheating of the S4. Mine will get warm to hot just by downloading from the Play Store and playing withe the menu. I tried a factory reset, microsd reformat, etc.
Does anyone else with the tmobile version notice the phone getting hot?

I have tmobile version and it runs really cool

Sure - any huge data usage, (especially with 3g/4g/lte) will cause the phone to heat up in the cpu area - this can be coupled with high graphics usage, and/or high ram usage -
electricity generates heat as a waste product - it wont get too hot, but it will heat up.
My gs2 would occasionally get so hot i didn't want to hold it or let it sit in my pocket
My new gs4 got plenty warm when redownloading my podcasts, and durring the first google device restore.

For me so far, the only time it is noticeably warm is when I use the camera for an extended period of time. Haven't played any intense games on there though like NFS.

I find that my microsd card get hot when accessed a lot, but that's not new, same as in my S3.

Mine is hot too. I haven't done anything though.

I believe there is firmware update that is compatible with the I9505 Tmo variant. You may want to do some searching and check it out.
The main S4 forum is a good place to start.
http://forum.xda-developers.com/forumdisplay.php?f=2162

Heat is not the same thing as over-heating. These chips have a maximum operating temperature rating of upwards of 70c. There are a myriad of reasons why any two devices would operate at higher or lower temperatures including ambient temperature, radio actions (high-throughput or low signal recovery), and of course running processes. There will always be people who think their phone is "too hot" since it is a purely subjective claim.

yeah honestly is at 40c and thats beyond hot!!

Yep, mine heats up on the top back of the phone. But it doesn't overheat when I'm on the phone though. I talked for over two hours and the phone stayed cold. But if I play around with menu and installing apps, it gets noticeably warm. I used S2 for two years and didn't remember it getting this warm.

mine heats up probably i am using 4g data and voip app to call people
but it heats up top Samsung name area like u can feel it in like 10m lol

Like others mine heats up at the top back at times but never to a serious, uncomfortable degree. Pretty sure my Blaze would get hotter at times from less taxing usage.

So hopefully this is just software related issues and not hardware.....

Try turning down the brightness of the screen, I saw some reviews say the density of the screen adds majorly to the heat.

I have to wait 20 days to exchange it. I could return it but my micro SIM card doesn't work on the S2.
Anyway, I just received an OTA update.....

I've used my micro sim in a GS2, a MyTouch slide and a G1. It will fit, just line up the 3 pins to the 3 plates on the sim and it will work

Left Side gets Heated

I was reading on the Note 8 the other day and started noticing that the left side of the tablet gets pretty warm/hot. Is it just me or does anyone else have this issue? The rest of the tablet remains cool- just the left side around the middle.

This issue already discussed before. It is quite normal for a device to get some heat. Anyway, I think there is a big difference between warm and hot. If your device really gets HOT, then it is a problem. My device gets warm as well as you described, but I wouldn't say it gets hot or uncomfortable to hold. I think the temperatures quite similar to my SGS3.

CPUs and GPUs put out heat. Batteries put out heat. The more intensive the activity (particularly watching video, gaming, internet use and GPS) the more heat will be generated. This is a fact with all tablets, and computers in general. I'd think it was strange if the device didn't get warm somewhere. Heat on the left side is completely normal, although not sure what component (CPU, battery, etc.) is located there.
Now its impossible to tell what OP means exactly by "warm" or "hot" as this are not quantitive in any way. It shouldn't get hot enough to be uncomfortable (or even hurt) to hold in any way. Excessive heat may be an indicator of a faulty battery or some other hardware defect. But usually not. And the device will shut itself down long before a temperature is reached, that will hurt anything (if that is what you are worried about).
There are ways for the system to tell you the temperature, but I think its only at one location (CPU?) which may not be the problem area. So measuring this way may have limted usefulness in real life.

That is the location of the cpu unit so I wouldn't worry about it unless it gets very disconcertingly hot.

Im using the Sansung OEM cover. Holding it in portrait mode, mine gets "warm" on the left side near the edge... but only when its in my pocket and its in sleep mode and wifi is turned off. Kinda fels like my BlackBerry when its polling for a tower, it gets real warm. I have a N5110 wifi no radio so trying to determine why the warm up.

Heat "problem"?

Hey thanks for all your input guys. It's good to know I'm not the only one experiencing these problems. So far, I don't think it's bothering me to the point that I wish to call Samsung up for a replacement. It does get a bit warmer especially if I have the pen out and writing some notes. I do also understand it's more than likely that the cpu is located there but I've never had a warming problem w/ other smartphones and tablets I've had.
Either way, thanks for all the input!

I agree

I agree with you, my father's got an iPad mini and the gadget doesn't present warming problems and battery life is much better. Do you think all Note 8 devices present the same problem? I'm thinking seriously of replace mine for a brand new Note 8.0 but if it presents the same problem, I'll be wasting my time...

Serious over heating issue

So ive had my Tmobile G4 for about 3 weeks now. Ive been using the G series since it started. I love the G4 but wow ive never had a phone with this type of heating issue.
There is not a time when the phone js not at least warm to touch. Few times a day it gets to the point where its too hot to touch at all. Forget about making a phone call way to hot to lut against face.
Im not doing muxh of anything either. Web browse etc... But its hot at idle screen off just sitting there.
Anyone have issues with heating? Multiple times its given me the over heating message and shuts off phone.
Last night for example it got to 80c.... Thats fricken hot!
Could factory reset help it? I dont know what to do at this point? Am i just having to get a replacement? As i type this from my g4 sensors showing high 60 to low 70C.
The heat is generating from the top half of the phone btw. Like at the camera it feels like.
Any suggestions or help? Thanks

Is the battery draining abnormally fast? Check the usage for play service, could need that fix

If you live in a hot area like me, such as LA, then you probably experienced phone shutting down while using phone as a GPS due to the overheat.
I've never Had that problems with all of my previous phones but I'd give few software updates for optimization.

Yeah battery is draibing very fasy. I use a battery monitor and nothing is sucking it up.
Also, i live in Arizona where it has been 110 degrees daily. Though it hasnt shut down from heat outside or when using gps yet.
It shut down with over heat warning last night in my apartment where its 67 degrees in here while i was on google.com just browsing. So im clueless right now.
I just cleared cache partition and booted to safe mode to see if it runs any better.
I can leave my phone on my table for an hour and pick it up and itll still be scorching hot doing nothing. Its literally never not hot to touch.

Yeah. That's the mytmobile app... Unchecked all the boxes in the settings. Helped me

My 1st Tmobile G4 Online Preorder had some problems mostly screen. I sent it back. I went to the store and bought one. That one was always hot as well. It was always throwing warnings at me. I had Gmaps on in my car with the AC on and only 70F out the time and it shut down on me. I called Tmobile and did some master reset etc and still was the same. I finally just went back to the store and told them to exchange it after they seen how hot it got in store. Tired to tell me I was at 15days when I went back in but I called in a few days before and asked what day was the 14th Monday or Tuesday I guess they count Purchase day as day 1 and that's what I thought but the person I talked to said no but they called Manager and they honored it. This phone finally seems to be good a few little issue's but they should get worked out soon with software we all hope. The 1st 2 phone's I had the Update Pushed to my phone the 3rd one was already on the phone so might be newer batch ? I was not happy spending over $600 on the phone with the issue's I had on those til this 3rd one which is good so far.

Then I'd say that even when it's doing nothing, it's still actually doing something, maybe just something it shouldn't be doing.
My Verizon G4 ran warm, and I was disappointed with the battery life. Different monitoring tools were unable to point me to what app (?) was causing the problem. Sometimes it would stay cooler after a reboot. Mine was never just constantly hot, however. Mine would be cool sometimes when sitting around, and then sometimes warm. Like taking it off the charger in the mornings, some days it would be cool, others it would be warm (~95F or so), when it had been just sitting there with the screen off.

Just now for example. After i replied here i out my phone on my table. I just now picked it up and it was 74 C. Scorching. Like its just gonna melt ibro a pile of G4 goo lol.
I guess ill call my store on Monday. Safe mode and clearing cache partition didnt help at all.

Are you using a case with it? I recently had overheating issues and figured out that the leather wallet case I was using was causing my G4 leather to overheat. It went as high as 112°5F But as soon as removed it it went back to normal.

Nah I have the black version normal backing not the leather version. I have the thin Tech21 case but i took it off a week ago to see if this helps.
As im typing this my phone is at 75C which is 167 degrees F! So hot!
Possible a Facorty reset could help? I really dont have many apps installed right now either. Since its relatively new ive been slowly installing apps. I started blank, didnt install anything from backups etc. The apps i do have installed are pretty basic. Nothing syncing or running. Ive been clear the recents aswell just to try. Frustrating

Have you tried turning off WiFi? I've noticed occasionally that my phone will constantly drop WiFi on my home router and reconnect a few seconds later, repeating this until I restart the router. All of that constant disconnecting and reconnecting makes it pretty hot...

Yeah its happening regardless. I turn data off when im on wifi and my wifi never loses connection, it stays constant. Though i did try a few days ago using no data or wifi and same dral, just hot.

Have you tried a factory reset? I leave my wifi on and stream music and everything. The only time it gets warm is when I Fast Charge. But I mostly wirelessly charge so its still cool.
Maybe you should exchange it.

I'm second on that doing factory reset. Seems like you have a corrupted profile or rogue app, or both.

I were having over heating problems on my G4. It were so hot at one point that my 6 year old daughter picked it up to play a game on it. The phone was that hot my daughter actually started crying cause the phone burnt her hand. This is not good. I have an awful lot of applications on my handset, over 300 so before I contacted LG I did a LG backup and reset. I restored probably half the apps what I had and a week after I haven't had a problem and the phone seems to be running as it should. The phone isn't even warm.
My theory is the G4 has 64bit processors. The snapdragon 810 processors were known for over heating and the G4 uses the snapdragon 808 processors for this reason. The 64bit processors deal with twice the data at the same time to the old 32bit processors and this contributes to them getting too hot. I feel that a few tweaks by developers and updates from LG is what's needed to combat the over heating. Time is our friend here and a bit of common sense. When you install a new app and overheating occurs then just remove the problem app. I always see how the app affects the handset now for over heating problems.
The 64bit processors in the G4 are new and need to have some updates to combat the overheating I feel. I recommend a system restore, debloating and only using the apps what you need.
I remember when pc's went from 32bit to 64bit processors. There were processors burning out, melting, water cooling became popular and bigger fans to combat the over heating. In time it sorted itself out so I feel this is the case for the G4 and other new handsets running 64bit processors.
Hope this helps.

Did anyone try unchecking the boxes in the my T-Mobile app? My phone went from 50% to %5 in less than 30 mins running crazy hot. You could also try uninstalling the app updates, or using the debloater tool on xda to disable it.

Same here, although not so hot that it "burns". iPhone 6 got warm but never so hot - software improvements should help combat this over time. +1 on the debloat tool.
One may argue the dead air via removable back cover can act as an insulator vs a compact design. Maybe just get an Otterbox/Thick case so you can't notice the heat as much? Could possibly lower battery lifespan though.

I've had my AT&T G4 for a little over a week. The first couple days the battery life was horrendous so I did a factory reset. The battery life improved greatly however that's when I noticed the top half of my screen getting unbearably hot. Another factory reset didn't solve the issue. So I talked with an AT&T Rep and am taking mine in for a replacement now. Hopefully will resolve this issue. Will update.

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 LG G5 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!

i think the G5 heats a little bit too much
today i was simply downloading Hearthstone (800MB approx) and in standby it heated too much

i think its quite excellent actually.
i could not notice any throttling during gaming etc. well maybe thats just because even the gpu is idling at <15% during asphalt 8 play

I had zero issues with thus device heating up until last night... I was at the movies with the fam.. In the theater I only had 1x for data and the phone got hot while searching for a better data connection. Cooled right down after leaving the theater.

Coming from an htc m7, so a huge step anyway... Phone is top!

This was one of the first things I noticed because I used the gps probably 45 mins after taking it out of the box. I watch YouTube vids for around an hour a day and after a while it does become noticeable but I have to be honest; it really doesn't bother me all that much.

Can feel warm and a little uncomfortable in warmer weathers (20-30 Celsius).

Mine heats up a lot. I'm a little concerned honestly.

I don't experience anything unusual.

heres the deal boys...
Yes this phone gets hot when its used hard.....if your not incurring reboots while running it hard , then you'll probably be good
After a month buying this , I started getting reboots ....hot and cold
The first time I sent it in , they said to leave sim and battery at home...
I got it back and started the usual 30 or more updates from App Store and phone got real hot and started rebooting again every minute
even when it was cool...it rebooted but at a longer interval...
They told me to send battery in too on second go around...
Just got it back , it had a system update to do and then the 30+ app updates....this phone was getting a workout...
I did the App updates right after the system update with the optimization ....
I'm 20 apps into it...the battery cooled down and the apps are still going...
looks like they have a battery issue with these phones. If I don't report back , then all is good...

No, it doesn't mean that LG has an issue with the batteries. It only means that YOU had issue with YOUR battery.
I'm glad your phone is OK and it was just the battery.

Only got mine yesterday, but I've used it a lot in that short time and it get nowhere near as hot my previous 2 phone a Nexus 4 and G3 it gets warm but not what I would call hot compared to them 2 anyway, at its worst mostly watching videos it can get a quite warm, but gaming it barely gets warm, I'm loving it so far but time will tell I guess but so far so good.

Mine heats up too, specially while using Snapchat or YouTube. Haven't played Asphalt or other graphic-intensive games, so I can't comment whether my device has the same issue with them or not.

Mine stays quite cool during heavy usage, it does get realy hot while charging though. I expect this is the same with others?

Coming from the Samsung Galaxy Note series (Note 1 - Note 5), the LG G5 gets pretty hot even when idling.... My solution? Waiting for the Note 7 to be released and then goodbye LG!

Check what's running in the background. Mine is very cool (H850).

Better than the V10. My old V10 overheated while I was using Skype to the point it shut itself off. Had no problems with the G5.

I'm so excited for some Pokémon Go! ... But I assume with high precision GPS, screen, camera, connection, my phone's going to get spicy hot. It warms up easily, otherwise, but it gets hot to the touch sometimes while charging.
