Those of you that have your hands on the note 4 already. Does it seam to get pretty warm while using it? The back side to me felt a lot warmer then I would expect from a portable device. I have to be honest I am used to having a hard case on my note 3 so maybe this is normal.
Thanks for your input

I haven't noticed it myself but it is not unnatural that a device gets a bit warm with extended usage. Downloading, streaming, gaming etc will somewhat stress the device. Especially the more you're doing at one time. Happened to my Nexus 5 all the time.

and, since you are in Florida, its still summer there I assume, so its bound to be warmer than it might be here in the beautiful midwest
plus, getting a new phone warm is gonna happen, since you probably havent put it down for more than 10 minutes so far

Thanks. It did take about 20-25 minutes of solid usage before it started to warm up. I do not typically keep the phone on that long but of course i had to configure everything over again so it had longer then average use on it.
Just got mine today and it got a little hot when I applied the OTA update! I'm going to watch it!
Mine got pretty warm after rooting and working it to apply all of my root apps. But it's not hot enough to worry about.
Let the phone settle in. You want a hot phone. Record 4k video for 2 min.
NOTE 4
It definitely gets warmer than my m8 did. Nothing alarming though.
Mine run very cool under heavy usage and i play lots of graphic intensive Games one of those games being Solforge which use to get the Note 3 very warm...but note i got Power Saving restrict cpu performance on which I think drops cpu to about 1.3Ghz each
Mine is far cooler than my note3 and note2. Very heavy use and its rooted , never warm to the touch

Where did u get that setting from
NOTE 4
Hey guys... I've been a long time lurker here at XDA, always learning lots with the great work done by the devs and experimenting with my devices accordingly.
I know that this isn't for the faint of heart, but I bought a high performance thermal pad to replace the stock one on my n910c. I always noticed that the cpu would throttle and reach very high temps. First thing I did was to undervolt my phone when I was on KK 4.4.4 and that helped a little bit.
But then I went the extra mile to see how things fared... well, opening the n910c is a pain and there's some risk to damage your screen/digitizer if you're not careful. I was lucky enough that all was working when I put it back together.
For reference, I tried Antutu several times throughout the 4 months I've had my phone and the best score I had before was a 54000 when underclocked and after I placed it in the freezer for a few minutes to experiment... At normal room temp (around 23C) the best I got was a 51000, in KK or Lollipop.
After I got brave and did the pad change, I got 54469 Antutu score at room temp (around 23C). Having said that, in everyday usage nothing has changed and the phone is great as usual.
I'm running the latest BOB4 Lollipop update and I'm currently not rooted. The big score was in my current configuration. Btw... I know it's incorrect and I deserve a slap for this, but I did the update to Lollipop the "dirty" way and just wrote it over KK via Odin... it's not pretty but it's working just fine. Eventually I'll have the time to do a factory reset and do a clean install, but so far, so good with performance and battery life.
I used a video on youtube on how to disassemble the Note 4 and obviously the guy had an easier time with his phone than me. My glue for the screen was very hard and I had to use a hairdryer to help things a bit.
The thermal pad I used was the Fujipoly / ModRight Ultra Extreme 0.5mm - Thermal Conductivity 17.0 W/mK
A couple of things to note: removing the original pad has to be done with great caution as you can easily scratch the surface where it's placed; the surrounding area of the thermal pad is raised, so it's super hard to cut the pad to the perfect fit (took me a couple of tries and I hate waste). And as usual: do things at your own risk!!
Sorry if I was long, but that's why I'm crap at twitter...
Cheers!

Good job. BTW I got 55k at 18 degree room temperature on BOB4 and 4600+ geekbench
Hi submano in 2018
I bought a used Note 4 VZW and i found out that it has 50-60C in standby, which is not normal
a friend has a Samsung Note 4 and he inspired me buying the Note 4 for my plan to test MHL usage, and his phone does not get this hot (though it is not a VZW, too)
for now I throttled CPU so that the CPU never heats over 65C, it got 85C in heavy usage
So after researching a lot I found out that the LDI (Liquid Indicator) is Pink, so most likely this Phone got some water once.
It is working still good just too hot
Would you please share me the special high performance heatpad type or/and a link where I can see that exactly?
I could try to fix this phone without mainboard replacement by installing a very good and new heatsink?
Any opinions on my plan?
Thanks a lot, ant0nwax
I've searched around and couldn't find any good threads about this:
My note 4 (N910U) gets pretty hot when I'm playing regular games (Tsum Tsum, Wind Runner) and I'm thinking that this is what is causing it to lag.
I.e. When I start playing everything is super smooth, and then about 2-3 minutes in when the phone is getting hot, the frames start dropping and it lags pretty bad.
This happend with my note 2 as well. Is it normal or should I try to send it in to samsung somehow? (in which case does anyone have any experience with samsung customer service? I bought the note 4 from HK but I live in Japan :/)

I encountered something like this before even without playing games. Check if you have this issue.
http://forum.xda-developers.com/note-4/general/upper-screen-getting-hot-t3103904
My Knox is already turned off and theres been no real difference from before.
edit: Looks like setting it to force GPU rendere helps slightly overall (the sum off all things since some parts get much nicer some parts are the same, a few parts are laggier... )

Actually by enabling that option will affect your battery. Haven't done that on my Note 4 but tried that on my previous phone which is LG G2. Definitely it will be faster on rendering but it adds consumption on the battery. And also if the CPU is still overheating, the speed will still throttle down and still affects the applications that relies on CPU. Did you do any customization? If yes, incompatible kernel can be an issue also.

Try installing this application. This application helped me track the application that is hogging my phone which is the Knox on my case. Look for a process that has a high cpu usage.

CPU throttling plague is main disadvantage of this phone (and many others too).
Samsung should be aware of this, and they are, but don't give a s**t. This expensive Phone lags as hell on some more demanding games.
For instance, Crossy Road lags after few minutes of playing, Ski Safari too, Subway surf....
No more buying Samsung s**t if this issue continues..
I feel sorry I sold my Note II, never had this problems with it.

Under clock it slightly. That will stop it reaching the temperature that throttles the CPU/GPU all the way down, but still keep good enough performance
The CPU's don't throttle very aggressively and work the clock speeds down fairly evenly so you won;t be able to manage it better yourself by underclocking.
the GPU on the other hand stock uses some pretty crazy throttle steps which knocks the clock speed way down in one step which is probably what most people notice while gaming. You can try fiddling with the max states to try and work it better, but if it gets hot enough to throttle then it will just settle down to it's base state of performance.
I do wonder what people expect when they states these things are 'issues' or it's 'Samsung ****'. Welcome to the world where phones are designed for burst performance only. The Power consumption of pretty much any phone SoC from the past 4-5 years is high enough that clock speeds will be dropping (way) down once you put any extended load on the device. There are SoC design choices that can help with this (very wide cores running at low clockspeeds/voltages) and process node improvements usually come with an increase of steady state performance but there is simply no getting away from the fact that phones can't maintain performance because they are just too small.
getting more performance when you're limited to maybe 2.5watts long term TDP is a challenge. Only way to actually improve it is to undervolt your device, which can help quite a bit if you can drive the voltages down by a decent amount.
OK, I would ask which flagship Samsung phone not older than 2-3 years throttles the least? I'm ready to swap it with Note 4.

The Note 4 probably runs the coolest. I have a N910F, it only heats up with very heavy games like Real Racing, the CPU generally stays cool though.
Maybe activate CPU Power Saving and Force GPU rendering to try balance out the heat and power? Thats what I would do.
Currently I'm considering buying this phone, and I've heard mixed opinions on the heat issues. I've never owned a Snapdragon 810 device, so I really don't know what to expect. Is it enough to consider getting something with an 808 instead? Will it overheat in the middle of taking a 10-minute video? How much does it take for it to get too hot to use?
I have used this phone for a couple months. I don't do any heavy gaming but I have not experienced any heat issues. My M9 was hotter under the same usage conditions.
I asked the same question here: http://forum.xda-developers.com/zte-axon/help/heat-issue-t3199918 Funny thing is that only augie answers, but i am sure there are a lot more users of Axon. Share the experience
I do not have any heat issues.
Augie is definitely the most active member of this forum. Pretty awesome and helpful. My axon does get rather warm on memory intensive games. Not graphically intense, mind, but games with a lot to process on screen. It's never hot enough that it's uncomfortable to hold and I don't see any of the throttling that people complained about with the 810 either.
No issues with heat here too. I did notice it getting quite warm before I hid it away in the case but no more than I noticed with my OPO.
So I have the 4G version of the s20 fe and it overheats alot. When I am gaming or even charging the phone it heats up quite a bit (around 36-38*)
Software update did seem to fix it a bit but it still heats up. Any soulution?
P.S: I am not rooted. I use it at 120hz
there are things that can be done by rooting but you probably wouldn't like the idea of them if you game.

Thx and also the charging speed is VERY SLOW
Fast charging is enabled and I am using 15W Charger
Any way to fix this as well?
idk... clean the port out and clean the cable connection.

If too cold or hot fast charging will not engage.
Best start temperature is 85°F
Keep below 100°F when charging/using. Use a damp microfiber cloth and/or fan to cool.
Find apps causing the drain.
Try disabling all power management* first then get to it.
Clear system cache and system logs.
Cloud backup apps are prime suspects.
Disable Google play Services when not needed.
Do a factory reset if you updated the OS version or if you used Smart Switch to transfer data/settings from a different phone.
*can cause excessive battery consumption and erratic behavior.

they're the 2 most powerful cores on your chip, some believe they are the reason for the heat.

it's not really an app thing it's an Exynos 990 thing, over on reddit almost every single user reports terrible SOT and extreme heat even on mundane usage. Samsung discontinued the 4G version with the 990 but played it off as being related to a silicon shortage.

My Snapdragon variant was a hot running battery hog at first. So I'm not convinced it's hopeless.
There are also 2 heatsink variants that may have been used. The 990's perfomance score is only slightly less than the Snapdragon.
The fact that it's spiking the cpu usage points to a software issue. Even if the faster cores are online for only seconds each minute it will drive up the temperature/battery usage substantially.
That will cause these symptoms and it's common on all the Note 10+ variants and other Samsung models as well.
Disable all power management, it's a known trouble maker.
Track down the apks causing this one by one, and deal with them on a case by case basis.
There are likely quit a few and many aren't needed or used.
people were getting 3.5/4 hrs SOT from a 4500mAh battery and heat that made it uncomfortable to hold. Samsung took several runs at fixing it and achieved nothing then discontinued it. if it was only a high level software issue that's a comparatively easy fix for an OEM.
one guy uploaded graphs for his cores and the 2 big power cores ramped up to max and just stayed there. seriously poke your head into r/GalaxyS20FE and have a look at posts about the Exynos or Exytoast as some call it.

Um, don't think I'll get the Exynos variant if I get another N10+... you're right it seems to have flaming reviews.
