Hi all!
I have been noticing that the tablet can get fairly hot where the CPU is, and under load it can reach fairly high temperatures - CPU prime got it up to over 90°C for me to the extent that I had to shut it down.
To be honest, it doesn't really impede normal usage, and normally it seems to reach slightly over 70°C under higher workloads. I suppose that's not unheard of for ARM devices and might not actually count as overheating. But after seeing this video on the Teclast X98 Pro and some other info on modding in tablets, I was still wondering if there'd be a way to improve the cooling on the Note 10.1 2014 to get lower average temperatures - potentially, that should also lead to more stable and fluid running under high loads, as there won't be any need for throttling, and it might also be good for the components to keep temps lower.
So I guess my main question is if anyone has undertaken anything of this sort for this or comparable tablets? @thebadwrench has recently posted a very useful guide about swapping the battery with a rare shot of the inside of the tablet: http://forum.xda-developers.com/showpost.php?p=66124495&postcount=13
I was thinking what the most sensible way could be to improve cooling of the CPU, which should be the small shielded unit in the lower centre of the second picture. People seem to have had good results with copper, but it seems fairly crowded in there and it might be hard to get it installed without shortening anything.
Aside of the more practical question, I'd also be interested in the typical temperature that other people's tablet reaches and if you have any better apps than CPU prime to produce high CPU load - possibly one that shows CPU temperature at the same time as well? Currently, I'm having another app running to check CPU temp (CPU prime for some reason only shows the battery temp).
Looking forward to everyone's answers!
PS: @mods Not sure if this is the right section of the forum, feel free to move if you feel it fits better elsewhere.
AFAIK Microsoft intended to fit an innovative kind of heat sink into their Lumia 950 and finally produced a standard design w/o particular cooling devices due to difficulties.
I have no clue how anything could be done. Except replacing the back cover with something thicker, offering room for heatsinks, fans, peltier elements or such.
But the Note should at least have thermal throttling and emergency shutdown features, like all current phones, which will throttle within the first half minute under full load.

Similar temperatures are note uncommon in mine. One suggestion is to use a small desktop fan and aim it down at the tablet when your demanding alot from the cpu. I sometimes do that with mine and it actually brings the temperature down about 15 degrees. Its not a mod, but it does work
Thanks for your answers so far!
@lecorbusier yes, I suspect it has throttling, but in the interest of better running it would be nice to avoid throttling when possible. I'm not sure about the effect on battery life - throttling might be good in that a reduced frequency might need less energy, but running hot in the first place is probably bad for battery life.
In fact, part of my problem might stem from either the ROM or some apps I am running - Squid on temasek's CM13. Maybe I just never noticed this before, or didn't use squid so often, but I've noticed that the last couple of days CPU gets up to over 70°C at times with just some writing in squid. Not sure if this is normal, will probably post it in the CM13 thread. But my general idea/wish to improve cooling still stands independently of that.

That sounds like an effective method (and I guess in a way one might call it a mod ). I'm thinking about something more portable, and hence passive though.
I will probably try opening up and having a look at the current cooling mechanism to see if adding a copper shim or a better silicone heat sink etc. might help things. Another consideration would be a modded case that contains some metal instead of plastic on the back side. That might help to take away some of the heat even though the plastic back of the device itself probably remains a poor heat conductor. Might be a complicated mod, but I'll see if I can come up with a way to do that. If/when I manage to get something done, or some new thoughts, I will advise here.
Any further input of course still very welcome!
Metal will disturb the various antennas.
A back cover replacement containing one or two fans, adding 1 to 2cms of thickness, and draining the battery with the fans while looking clumsy, thats the "best" solution I could imagine.
Or a back cover replacement containing one or two copper plates, cut and arranged in a way that the antennas aren't too handicapped. Probably you have to remove the various EMI shields to be able to establish direct contact between the chipset and the plates. That is, if the chips don't have contact with the shield plates.
I think this will be something never been done before, but probably after.
Like the battery mod for phones, where you solder one battery together with a second one and cut a hole in the back cover, that the now double-thick battery may fit. That's already been done.
Good point about the antennae, I hadn't thought about that! That also makes sense of the lack of metal cases (facepalm). Might still try modding a case with some metal in some spots at some points, but good to keep in mind how this might impact wifi and bluetooth.
My plan was to see if there'd be a chance to fit some slim copper plates in strategic position on top of the CPU inside the normal case. I'll have to open it up and see how much, if any, space there is - but will probably try this first on a Galaxy Tab S 8.4 that I rely on less for productivity (and that does actually get way to hot, to the point of self-shutdown). Whenever I find the time that is...
Will report when I get around to doing anything on the Note (and might open a topic at the Tab S forum in case I do try a mod there first).
I added a copper shim for cooling to my Galaxy Tab S (will put a more detailed post on that forum when I find some time), which seems to have helped to control temperatures somewhat better. I had two odd crashes, but had some before I did the mod, so am relatively confident that's a problem of the ROM rather than my mod.
Will probably try it on my Note as well soon and report here for anyone who might be interested.
Have modded my Note now, and am planning to post a more detailed description some time (won't have time before next month though). It had clearly improved temperatures and stability of my Tab S, but I'm not sure how much of a difference it made on the Note 10.1 2014 because I didn't measure the baseline temperatures before the mod right (used CPU Prime benchmark which seems to have general stability issues on the temasek ROM I'm using).
Currently, I have idle temperatures of around 30C, under normal use it would get to 40-50C, and under stress (app StabilityTest) it goes up to around 89/90C after 5min and to 92/93C after 10min.
I'd be quite interested in what temperatures other people get on their devices without any modification?

Thanks for the update. I did some baseline checks for you, using the same StabilityTest app for consistancy purposes. I am also on temaseks build, cm13 more specifically. I run temaseks 12.1 build just as often as the cm13, so I will run the tests there as well. I revert back to my stock rooted kitkat rom about 1 or 2 days per week so I'll check the temps on that ROM as well.
So, at idle I'm a little warmer than you, hovering between 37C and 40C. Under normal use (like web browsing) I'm between 50C and no higher than 57C. Under stress (again, using same app) I was at 90C at 5 minutes and 91C after 10 minutes. So slightly warmer on low end, nearly identical on the big end. I have the samsung flip cover thats specifically made to fit the 2014 edition on mine, so that could account for my slightly warmer temps. Its worth noting that when gaming on a VERY cpu demanding game, I never reach anything above 78C. Its probably one of the top 10 most cpu demanding games on play store and BY FAR the most I ever demand from my CPU, consuming a whooping 1.5-2Gb of RAM at times.
I'll check the numbers on my other 2 normally used ROMs here in the next few hours and I'll post those results too :good:
On a side note, my galaxy s6 phone (completely stock, near new) averages nearly indentical cpu temps and after researching the matter on it, I found that those temps (on the s6) are what others are getting as well. So it seems that, generally speaking, samsungs might just run with warmer temperatures. I did see somewhere that 100C is kinda the 'YIKES!' point for them and that they start clocking down around that temp to prevent permanent damage

Ok, I've done some testing with a few different ROMs and I think you might be as susprised with the results as I am. First of all I need to correct myself in my last post. The initial testing I did was on temaseks unofficial CM12.1 build, not on the CM13 build. I have now tested on temaseks cm 12.1 and cm13 builds, my stock rooted & debloated 4.4.2 ROM and an old nandroid backup I have of hyperdrives 4.4.2 ROM. Heres what I found...
Temaseks CM13 build ran the hottest and was by far the most stressful on the processors and therefore ran the hottest. It consistantly kept the CPU clocked at near max (even when set to "ondemand"), whether needed or not (with no background process running) and would only reduce power when forced via CPU governor or was at the safety threshold for temperature, which I can now comfortably say is about 95C. Tablet was slightly warm to the touch at idle with a temperature of between 50C & 55C. Under moderate load temperature jumped very raidly to the mid 80C range and then would stay there pretty steadily. Under heavy load, CPU temp quickly peaked at 94C where while watching the CPU output, it was obvious the CPUs were going in & out of protection mode as they would drop to 1600MHz, then peak at 1900MHz, 1600MHz, 1900MHz & repeat this. I didnt let this go on for more than about 2 min before shutting down and allowing tablet to cool.
Next, I repeated tests on both touchwiz based kitkat ROMs I have backups for. 1 of them is stock, rooted, debloated and un"tweaked". The other is stock, rooted, debloated and tweaked. Both ran MUCH cooler, peaking at 80C & 82C. These were ocassional spikes and actually averaged around 75C when under heavy load. Now comes the good news...
I have identified a major contributor of excessive CPU temps. When testing on the touchwiz ROMs and observing CPU clocking in relation to CPU temps, I found that the governors are set lower in these touchwiz ROMs. They were a steady 1300MHz with the occasional 1600MHz spike. They averaged 55C to 63C under moderate load and when under heavy load never reached more than 82C.
So, I am now back on my long time daily driver, temaseks cm12. 1 build and I'm ditching the CM13 build entirely. At least for now. I have set my CPU governors down to 1300MHz and with heavy load for nearly 30 minutes (gaming) my CPU peaked at 85C. So my findings were that CM ROM has overclocked the CPUs excessively. They are set to 1900MHz, which has become obvious to me brings them right up to their temperature safety threshold, 95C. It seems Samsung clocked them at 1300MHz and allowed for occasional spikes above this point, keeping them at a maxium & slightly more reasonable 85C a full 10C cooler than their maximum safe operating temp.
I never expected I'd stumble on not only a source, but also that I've been utilizing the solution for months. I should add that governing the CPU lower has had absolutely no effect on performance. I regularly shut down 1 or 2 CPU cores as it is. I found that the tablet will run perfectly under normal use with only 2 cores. This reduces temperature and increases battery life. Sluthing can be so much fun sometimes, it was right in front of my face I just never put 2 & 2 together lol :good:
Thanks for your detailed comparison, that's very helpful indeed! In light of that, I think my mod has indeed given some improvement, as I don't reach over 90°C on CM13 until after 5-10 min, albeit with some throttling to 1700MHz after about 10min.
I've always had the impression that the current CM13 builds are a bit more CPU hungry and run warmer (possibly that triggered my thinking about a cooling mod in the first place), so it's very interesting to see that backed up experimentally! Interestingly, I've had mixed experiences with CM13, almost like two "modes" of running - sometimes, it runs pretty warm, roughly like you describe, but at other times it runs fairly normally around 30-40°C without problems. Haven't really figured out what the problem is and am having occasional instabilities/reboots as well, so I might actually also return to CM12.1 for the moment too.
While the higher CPU clocks (although 1.9GHz is the specified clock speed, but I get what you mean) may explain the heat and slightly better results in Geekbench I've been having with CM13, it's a bit odd that I still get the good result when the ROM is in the cool "mode" (it goes up to high 60s, mid 70s during Geekbench if memory serves well).
How do you set your governors? And have you been able to get the cores to switch on and off automatically as they do on some other devices? Or is this not implemented in the kernel or something?

Your welcome. I too noticed that on CM13 at times it seems to run alot cooler than at other times. Although the only time I ever see go as low as 30C is when its been asleep for awhile and then I turn the screen on (CM12 & 13). As soon as it wakes up it'll go to mid-high 40C to mid 50C (on CM12) or it'll go straight to high 50C to low 60C (CM13). CM13 definitely ramped up alot quicker when testing, almost like its either min or max CPU power. I like temaseks CM13 build, but for me there wasnt much improvement over the CM12 build. Plus there is a few minor bugs as well as the slight negative effect on battery life I noticed. Plus I was noticing that there was a bit of a touchy spot in the top right corner of my screen that when swiped from the outside in, it sometimes crashed my tablet. I wasn't sure if it was a fault in my tablets hardware or something software related and I'm still not 100% positive which it may be, but since I began taking notice of when it was happening, its only ever happened on CM13. Thats also part of the reason I think I'm going to hold off on using the CM13 build for awhile. CM12 build is overall just more to my liking I guess... more to my tablets liking as well.
After posting yesterday I looked up some specs on Samsungs website and you are 100% correct about it being 1.9GHz. This is the spec copy/pasted off their website... Exynos® 5 Octa (1.9GHz Quadcore + 1.3 GHz Quadcore). The second part stands out because 1.3GHz is definitely where the stock rom was trying to maintain its CPU frequency when under heavy load. Not once did it exceed 1.6GHz. Whereas both CM builds ramped up to the full 1.9GHz very quickly. So the difference is going to be HOW the processor steps up in frequency as opposed to what the frequency actually is. Thats where my knowledge on that kinda stuff ends. I'm a "let's figure out what failed and why" or "lets figure out how it works" type of person. Thats why I work on cars for a living. I leave the development and detailed technical mumbo jumbo to the devs and engineers. Troubleshooting methods are much the same for just about everything though, hince how I came to my conclusion yesterday. Just for grins I may load up PAC ROMs CM12 build, see how it does. too...
As for how I set my governor, it depends on what I doing at the time. I never fine tune anything, like I said, that's outside my realm of knowledge. What I do set is the governor to either interactive or ondemand. Interactive more for casual use and ondemand more for gaming. I also manually shut down CPU cores depending on my demand from my CPU. Right now, for instance, I'm running stricly on cores 0 & 2 with cores 1 & 3 turned off. My CPU max clocking frequency is set to 1.3GHz but its consistantly hovering at 650MHz, or .65GHz. Thats all I ever mess with and I do so mainly for battery life. It makes a noticeable difference (both charging and discharging) if I adjust those 3 things according to my use. And no, my cores don't ever switch on or off automatically. I do vaguely recall seeing them do that on a different ROM, but I don't remember what ROM that was... it was at least a year ago that I saw that. I'm sure that is something that is kernel related, but I'm just guessing on that one.
What exactly did you mod? Any pictures?

Hi thebadwrench,
Which app did you use to do all this modifications on cm13 stock kernel? Especially deactivating cores is very interesting. Can you see all eight cores? I'm using 3C toolbox and it shows it only as quad core and on voltage page I have two cpu cluster.(one clocked till 650mhz and the other till 1900mhz)
Under CM13 the cpu behavior is totally different as on stock Samsung roms because the small cores are more or less unused and clocked at max. only at 650mhz, Lol!
I watch also much more kernel warnings in ksmg and high temperatures for a while now on CM13.
Also battery runtimes are only 3,5-5h unlike 7-8h under cm12.1!
Sometimes the cpu is also locked at max. speed(1,9ghz), mostly after looking youtube videos or other heavy load situations. The only way to get back "normal" behavior is to reboot the device.
I see also only two used cpu states all the time it jumps between 250 and 1900mhz, the most steps in between are unused.
We can only hope a real kernel developer can have a look on this or we can cherry pick some usefull tweaks from another device with the same cpu chipset.

I use kernel adiutor https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor It also shows 4 cores but shutting them down is just a single click. In the attached screenshot you can see that I've manually unchecked cores 1 & 2 and on the CPU display (turned on via developer options) you can see that those cores are indeed shut down and not operating. I like the app's widget, allows you to set up as many different profiles as you want and then change between the different profiles on the widget.

Yeah, good news!
I am positive surprised that kernel Adiutor is working, seems we have build-in UCI, which is needed, nice! Using KA on my OP2 since a long time but there is no custom kernel for p600 cm13 roms so I have not tried!
Will try it now!:good:
Thanks!!

I replaced the silicone heat pad on the CPU with a copper shim and thermal compound, added some small silicone pads around other components (all under the heat shields) and added a .5mm silicone heat pad on top of the main heat shield to enhance contact with the back plate. I do have some pictures, but I want to provide a proper write-up and currently don't have much time as I'm moving. Will hopefully find a chance to give a more detailed write-up in May - sorry for the delay, but full report is forthcoming!
As for the CM13 issues, @joshndroid apparently implemented some changes to it in the last build, so I might check that out, although I agree that CM12.1 is probably still the safer bet for a stable daily driver.

Hi Franzli,
The kernel seems odd to me!
The small A7 cluster is virtually unused and clocked only to 650MHz @ 1200ma !! Normal is 1.3GHz @ 1200ma for the small A7 cluster on 5420! Also a lot of warnings and errors in ksmg!
No idea whether the A7 ever used or permanently in idle mode, Lol!
Also all 4 big a15 cores are always online, what means no hotplug driver available!
I don't know if we will ever see a good kernel for CM13 because of the missing sources.
Although the kernel is running and mostly stable it is far from "good"!
Power consumption is almost doubled, problems with overheating and sometimes cpu is locked at max. speed and the only way to solve it is a reboot.
I don't remember the cm12.1 kernel but he was definately better in terms of battery runtimes and reliability.
BTW, I'll also mod the device cooling using bigger copper sheets instead of the perforated aluminum sheets, thermal-pads and thermal-grease when I start changing my battery and usb jack, what is definately neccessary in my case!
Maybe I will buy one of the small heatpipes used in S7 or so when I find them somewhere.
It is not difficult to adjust it if needed, so that it can replace the heatspreader.
Mabye it is needed to isolate the heatpipe from the mainboard but nothing what a piece of kapton tape not can do.

Hi all!
[...] But after seeing this video on the Teclast X98 Pro and some other info on modding in tablets, I was still wondering if there'd be a way to improve the cooling on the Note 10.1 2014 to get lower average temperatures [...]
So I guess my main question is if anyone has undertaken anything of this sort for this or comparable tablets? [...]

Hallo there
Well I just did the job. I have also made a short manual and would like to share it with you. But first some things about me and my tablet.
I bought a used galaxy note 10.1 2014 edition SM-P600 couple months ago. I was really disappointed about the device performance. Switching from stock android 5.1 to [ROM][7.1.2]Resurrection Remix N for SM-P600 (n1awifi) [5.8.5][UNOFFICIAL][NIGHTLY] did some improvements in performance. But since I am a very heavy web surfer I was still not satisfied with the performance. I have also tried [P600][Touchwiz] Marshmallow Rom 20170622 and went back to RR because I can play around with the CPU governors and all that deathy audiutor stuff. Between very nice work Exynos Team and all the other developers...
Soon I realized that the SM-P600 becomes fairly hot in the backside. I took a look at the ifixit pictures. There was no other way finding good resolution pictures of the inside.
I ended up installing cool tool app. Well is there any other good app for monitoring temps, clock and load in overly?
Well so I added frequency, load, battery temp and cpu temp. You need to add cpu temp manually. I guess it is Label ->
custom label -> enable- Then you have to go fine tuning -> custom label -> path:/sys/class/thermal/thermal_zone0/temp. leace everything as it is. regex is (\d+)\d{3} and add postfix °C and prefix cpu:
.
So I went along and analysed heat and temps in the galaxy 10.1 2014 edition. Especially frequency-temp-ratio. And I can tell you this buddy is everything else than cool. Temps jump up so fast I can't tell you. Even some fast scrolling on ebay, facebook desktop web page in browser treated the Temperature to the hight 80s and soon the high 90s. I have also seen the things franzli mentioned before. Even light work put so much heat to the processor. Watching the frequency and temperature bounce was a pain. I could feel the pain that little Exynos 5420 must suffer of all the time.Throttling is the only ways this little buddy can survive To make it short I decided to do the cooling mod...
So lets see what I found on my journey ... I can tell you that's a big surprise
I opened the case very easily. You can find tons of videos on youtube or use ifixit.
Well I have to mention I am an electronics hardware engineer. So doing this stuff is nothing unique for me. And I have years of professional PCB manufacturing, repair experience.
Opening the case, adding some tape and this is what you get...
As you can see there is a little thermal pad applied to the aluminium shielding. And boooom there you are . Do you see all thet flux solder remains? How come samsung? Seriously?
This is the shielding close up with that thermal pad.
As you can see the FBGA package is covered with flux from soldering. So it is naturally, that the cooling in the galaxy is a pain. There can't bee any good heat flow.
So let's check that thermal pad.
woops that little buddy is kinda to small. I am sad to see this.
Well I cleaned the surface as good as I can with ethanol. After this I applied a new Thermal pad.
After that it looked like this.
Then I closed the shielding case and cleaned it.
So next comes the actual cooling mod. I added a big thermal pad.
I had to cut that little hook in the back plate. So that the 100mmx100mm copper layer will fit in shape.
And this is it done.
So what about the results :laugh:
The back plate fits perfectly. If you know there is a thin layer of copper you can feel it. But it is so less. I had no problem closing the case. Ahh yeah I had to tage it with double sided tape, so it is pressed down to the thermal. The back plate will do the rest pressure.
And really don't worry about the wifi interference. There is no worry. Because the copper layer is located on top of the bettery pack and shielding case. Why should there be any interference? I have tried. Reaching same wifi performance as always. No worries:good:
So what about heating. Well my galaxy note stays pretty cool.
I need to mention this is all mesured with the [ROM][7.1.2]Resurrection Remix N for SM-P600 (n1awifi) [5.8.5][UNOFFICIAL][NIGHTLY] I mentioned before.
I used interactive governor.
I reach in Antutu v6.2.7 about 57000 to 58000
In futuremark work 2.0 I get 4000
Here some pics
I am sorry for that high resolution pics. But I wanted best of (bad) quality. I used my redmi note 4 for taking pictures. If you can't read all in the pics, just open in new window.
There isn't any more throttling at all. It is hard to push to 85°C or above now. Just with synthetic GPU and CPU load on all four cores at once. And it takes a couple of minutes. But in real world you will never get it. With only load on one core my maximum is 69 to 72°C. The tablet fells pretty nice now. The warming in the back plate is reduced to a very large surface. So sometimes it fells as if your hands warm up the case.
Can you suggest me any ROm with a good overclocking potential? I have already tried this ROM. I really don't know why, but it keeps crashing all the time at 2GHz or 2.1 GHz. Even with no load at all. I guess the used kernel is bad.
Do you have any ROM suggestion for me.
If you have any quastions and things you want me to test write me.
Just wanted to share my experience with you. I didn't expect a dirty PCB, BGA and thermal pad like this. So what do you think about this.
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 Honor 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.
Then, drop a comment if you have anything to add!
I have not experience any form of heating where I could bake anything, but enough to make me aware of it. Of course heat during mapping is normal, gaming wise....I actually think it has been descent. Played Asphalt 8 for a good 30 minutes (thats my gaming time frame on regular basis) with nothing out of the norm. Could be better.

I always suspect it at much, though I find myself lacks of love to Kirin SoC due to almost no progress on custom development, and some sites reported poor performance of it, but I myself, who never play (or have any intention to play) any games on mobile device, use them strictly to communication usage (and some web surfing), I find Huawei's tradeoff performance over heat and battery life might very good concept.
I never care about synthetic benchmarks. I just need a device that can last long and stays cool all the times with my activities, and it never lags. My most demanding tasks might be watching 3-7 minutes of YouTube's videos for some times or navigating the roads with GPS.
But just like almost anyone else here, I can't stand the EMUI, just no. Still hoping Huawei will fully support custom dev with their new commitment.

We all hope huawei try to push sources for dev always and ASAP
tends to warm up a lil bit, bt no overheating.
Glad to know there is no overheating.
Mine gets really hot when you work the camera(s).
Every single phone on the market will overheat. Some overheat very easily, and some take a while, but is not a one that will not get hot until it melts (even if it takes months of you playing asfault to do it ). If you wanted a practical answer though.... no, my friend has one and it doesn't get too hot when playing a game on it for a few hours.
Once I almost burned my hand while playing on my OnePlus One and charging it. This phone keeps lower temperatures than my OPO so that's a plus for me.
This is a topic I am really interested.
My present phones, the LG G2 and the OnePlus One, get really hot, specially in the Summer. The LG G2 is the worst, as it has everything in the same place, and the Snapdragon 800 is a little less refined than the 801.
I do not play on my smartphone, and I only use GPS once a month.
I use my phone to comunicate (call, text, Facebook Messenger, WhatsApp and Viber), track my packages (Deliveries), watch some videos on YouTube and search quickly something on the internet.
I am a light user, but when I do something, that thing needs to be done quickly and right.
So, heat is a no-no for me.
This SoC seems to be a better option, even against the Snapdragon 820, which was my previous SoC of choice.
Actually this Honor 8 tends to get warm. And when you use the camera for some minutes it gets really really hot in the upper part.

What do you mean by using the camera?
- Having it open while trying the features;
- Taking multiple shots;
- Making a video;
- Taking HDR photos; or
- Other use, please describe your usage.

Simply having it open. It overheats very quickly. Seems to be an issue with Huawei p9 too, an owner told me.

In my opinion, I suspect that is a software issue.
To have a better performance and take pictures very quickly, the CPU and GPU are taken to the limit and have a more aggressive governor and higher minimum frequency.
I don't know. Could be for the dual camera though. Whose usefulness, by the way, is at least dubious.

Yes, I agree.
At least on the heating problem.
From the review of Pocketnow, it is clear than it has a positive affect on the dynamic range of the photos. HDR becomes obsolete, which is a good thing, as HDR uses more power from the phone, takes more time and requires to be still for longer.
Look, I've experimented with the cameras in every light condition. Covering the mono sensor and leaving it active. I myself could not really tell a single difference between the photos taken.I really don't.
I don't know how you are getting it hot. I have played games. Used the light for extended periods of time. Used maps. Camera, video. It has never been as hot as other phones I have used.

Thank you for sharing your experience.
Is it normal for this device to heat up from basic usage (such as browsering and social media).
By heat I do not mean overheating but it does make the hand feel quite warm.
This worries me alot since I get annoyed by phones who get hot with basic usage.
Would this be because of the sd870 chip?
For me it does warm up a little bit during normal use but it's way better than my previous phones, idk maybe my standards of phone temperature is different than y'all. And if it was running a SD888 it would be even worse.

Charging especially fast charging produce heat.
Charging is an electrochemical reaction that requires a certain amount of heat to charge properly. Oddly Li charging is a mildly endothermic reaction but resistive elements in the cell produce much more heat than is absorbed.
♤Do not use phone while charging as it will skew the charging curve.
♤Listeners to music (no internet streaming) on bt with screen off is generally ok.
Best start temperature for fast charging is 82°F or higher (85-90°F seems optimum on my N10+).
Do not let battery temperature exceed about 101°F while charging, cool as needed.
♤I use a fan and/or a damp microfiber cloth to keep it cool, works well.
Li plating will permanently degrade your battery and can cause outright failures.
Never charge a Li polymer that is near freezing temperatures.
Charging below 72°F or in high temperatures (exact value unknown, some say >140°F but this may not apply to Li polymer) My Note 10+ will stop charging at about 102°F so hence the 100°F limit. In any case temperatures higher than 90°F aren't needed for fast/optimum charging and only shorten the lifespan of the battery.

Nope, miui is chock full of bloatware and make these phone warm up even some basic task. Tried several custom room in our forum, no heat up at all
I think it has to do since its summer too, debloated through but it still gets warm using social if I'm outside or if its under the sun.
From my logic this has 100% to do with a higher end cpu since as I said my sister samsung a71 does not do that.
Mostly worried that the xiomi build quality is **** that's why I asked

Use manual brightness control. Try to avoid going over 50%... and don't use in direct sunlight. High screen brightness increases current drain/heat a noticeable amount.
You're on to something when it comes to brightness... Newer panels that are being used in the latest Chinese devices all have very high sustained brightness. Which is nice and all but no1 had considered how that will play in combination with the newest chips,
If you compare F2 and F3 the earlier model only had sustained brightness of 500cd/m2 whereas the newer model can sustain 900cd/m2 of brightness - that's a huge difference
Then what about chips? Both snapdragon 888 and 870 are dumpster fires ( Even the dimensity chips ) , while the performance gain is insane compared to last gen so is the heat output... And sadly even the gaming devices with cooling fans struggle to keep the chips from throttling. Take black magic 6 pro for a shameless example (snap 888), it reaches upwards of 55C on the phone body itself during benchmarking with no signs or intention for throttling down to save your hands- that itself should be illegal but no1 ****ing cares since how else are they gonna reach those benchmark numbers.... ( 54C can cause full thickness burns in a matter of 30 seconds or so )
I don't have poco f3 to check but from looking at stress tests on YouTube you can see that they are much more conservative when it comes to heat. It reaches only 42C during benchmarking then starts to throttle down and basically hovers around that temp 42C-44C.
The chips are already insanely good when it comes to performance but the cooling is pacing behind... So yeah it's pretty normal that your device is getting hot - so is every other device on the flagship market rn. Most you can do to solve that would be in this order > Get a peltier cooling device like blackshark fun cooler pro > Lower the brightness to what's usable for you and hope it's enough to somewhat delay the throttling > The last one would be messing with the phone itself like downclocking it or lowering the voltage. It's a cat and mouse game , the throttling will come eventually , the only way out I see would be the first option or the last one if you're capable enough to mess with that and are lucky enough to get a chip that undervolts nicely.
Cooling?
Simply use a damp microfiber cloth.
My Xiaomi 11 Lite NE 5G device is heating upto 46⁰+ in BGMI with Screen Recording and Max Brightness. Hows your?
Is this is normal?
please Help!
5G standard user:
Heating is much resolved by software compared to what was happening in the beginning. They apparently curb SD 780G and it become real 5 nm chipset. Normal phone use, multiapping with average brightness just make it lukewarm, huge improvement, battery also improved and is good enough considering amazing phone weight. And extremely snappy on MIUI 13, even faster than on 12.5.
Can't say about temp but I'm sure max brightness plus GPS or gaming must make it way above 45 degrees as almost any other phone (or in your case screen recording and max brightness; our displays are rather average AMOLED tech not LPTO so they need a lot of energy on max hence battery suffers). Less weight probably also means less metal inside so this phone must sometimes get hotter but it's still more than reasonable.

It is. Its name is throttling. It happens when chipset is getting too hot and processor/GPU has to slow down automatically as a safety measure to prevent it from damaging itself due to high temperature.
Mi 11 Lite 5G (NE) is pretty innovative design but also not the best choice for gamers as heat dissipation in those phones might be a bit affected because of less metal parts/radiators inside (to reduce its weight). Best would be to make a break or lower resolution/details. Or use fan blowing cold air into your phone in hands.

It's about the model/chipset, not your particular unit.
If you replace the unit with another the same model - same workload will again cause the same heating
For heavy gaming you had to choose a phone with more powerful hardware (and with the higher price tag)
Any "Lite" model is obviously not a top-notch gaming machine

Cannot 'guide' you. I didn't observe any heating (11 Lite 5G NE, MIUI 12.5.8) and I don't play any games (except solving 5x5x5x cube - but my brain lightly heats then, not the phone)
Consult the service.
If you are unhappy and if your return policy allows, return, pay the difference and take some Pro phone
Also do not expect any flagship with Snap 888 to be much cooler. Performance will be definitely higher but they tend to throttle too and heats like crazy if game is demanding.
Maybe Dimensity 1200 is better in terms of that and much cheaper.
According to the test from notebookcheck which always contains temperature the 5G NE should not heat when not in use. It has a much lower temperature than other devices.
Have a look if you have the wakelock bug. This would heat the device and drain battery.

And what if this unit is defective? How to find that this device is good in condition and others Xiaomi 11 Lite NE 5G devices facing the dame issues.
Wakelock bug:
I'm not sure how the menu is in English.
Settings (Einstellungen)
Battery (Akku)
Scroll a bit down
Change that list to "Details"
If you see "Wake/Awoke" (Wach) is a full line without any interruption, reboot. This resolves it, at least for this time.
It occurred on my device once, it is a Xiaomi Redmi Note 10 Pro. I would be astaunished if it could not happen on the 11 Lite 5G NE.

I really don't know, didn't observe (I don't use a lot my Lisa), hence frankly I'm also not interseted about - sorry (user like not, I'm not the Xiaomi helpdesk)
You can ask the service or exercise the return policy - if applicable (I'm not fully happy with my phone but I cannot return and take another unit or model)
Hopefully the answer from tag68 in the previous post can be much more useful for you
See the test on notebookcheck, there's a photo of a heatmap. Their measurement was the highest temperature when heavily used (benchmark) as 33.4 degree Celsius on the upper side, which is quite low compared to other models.
I have a doubt about what is measured during such tests, becaus my Xiaomi 11 Lite 5G NE overheats in direct sunlight like crazy. It cannot be used to take pictures, see anything on the screen.
I would not recommend this phone for a vacation trip where outdoor temperatures reach 30 or more degrees celsius. I got this overheating while downloading over LTE and after 4 minutes with outdoor temperature at 26 degrees, the phone simply shuts off GPS, BT, WiFi and LTE plus it shows the overheating warning on the display.
I had to turn my back to the sun to read the message, it is a very bad experience and I already regret that I fell for all these comments that the phone does not have any overheating issues. It has, big time and it is very sad that this is never mentioned in any reviews.
I did not buy a phone that must be carried in the dark and cannot be used in direct sunlight. This is simply a no go for me and I will return my phone at the next occasion for a refund.
Furthermore, I did the CPU throttling test and yes this phone with the SD 778 is throttling horribly, this is so bad. I returned my phone now for a refund.
Just as an example how other phones behave I have also tested the Mi 9 Lite, same throttling test, no issue at all the phone did not throttle a single bit whereas the Xiaomi 11 Lite 5G NE did throttle after one minute from 100% to 80% and even further down. This phone is not fit for it's task, there are too many compromises made to the size and thickness of the phone.
Just got my Oneplus 11 CPH2451 on the A09 build and I'm seemingly running into quite a bit of overheating on the device. Wondering if anyone else is running into the same issue.
From all accounts and various reviews this phone is suppose to run fairly cool especially with the 8 Gen 2 chipsets. But it heats up just booting up (cpu hitting 70+ degrees) and will feel pretty warm to the touch.
Gaming wise, running Brawlstars, which shouldn't be a graphic intensive game, for prolongs periods of time (15 mins+) will cause the cpu to hit 80+ degrees and battery to 40+ with the phone getting visibly hot and starting to thermal throttle. Even before that kicks in, game will frequently experience bouts of fps drops from 100+ to 60 and this is with forced 120Hz turned on.
I've tried resetting the phone and going back to A06 build and still experience the same overheating problem. Tried various geekbench and wildlife benchmark and it is getting comparative scores as other reviews so the phone should be peforming up to par.
All this is coming from an OP8T with the nameless rom which runs the game super smooth and does not heat up crazily like the OP11. This makes it all the more frustrating as the newer phone with the newer chipset seems to perform worse across the board. In many ways it seems like OOS13 is just poorly optimized and a better kernel and OS will fix the problem.
Also tried the same game on S23U (same 8 Gen 2 chipset) and it ran as cool as a cucumber.
A quick google search does not net much overheating issues on the OP11 so I'm wondering if this is specific to my device.
Anyone suggestions as to how to alleviate the problem would be greatly appreciated.

Well it sounds like you have a defective vapor chamber with temps that high unless your ambient is quite high too so see if you can file a warranty claim.

thats a bummer but how often do vapor chamber become defective especially on a new device? Will try to file a warranty claim but might be hard as its not purchased directly through oneplus and lacking receipt as well.

Vapor chambers can be defective straight from the factory. Just ask AMD 7900XTX owners dealing with the issue on their new $1K+ video cards.

I've heard that too on the 7900 but its the first time I heard about it on a mobile device, hence am wondering how gaming performance are faring for others with OP11.

Just got my Oneplus 11 CPH2451 on the A09 build and I'm seemingly running into quite a bit of overheating on the device. Wondering if anyone else is running into the same issue.
From all accounts and various reviews this phone is suppose to run fairly cool especially with the 8 Gen 2 chipsets. But it heats up just booting up (cpu hitting 70+ degrees) and will feel pretty warm to the touch.
Gaming wise, running Brawlstars, which shouldn't be a graphic intensive game, for prolongs periods of time (15 mins+) will cause the cpu to hit 80+ degrees and battery to 40+ with the phone getting visibly hot and starting to thermal throttle. Even before that kicks in, game will frequently experience bouts of fps drops from 100+ to 60 and this is with forced 120Hz turned on.
I've tried resetting the phone and going back to A06 build and still experience the same overheating problem. Tried various geekbench and wildlife benchmark and it is getting comparative scores as other reviews so the phone should be peforming up to par.
All this is coming from an OP8T with the nameless rom which runs the game super smooth and does not heat up crazily like the OP11. This makes it all the more frustrating as the newer phone with the newer chipset seems to perform worse across the board. In many ways it seems like OOS13 is just poorly optimized and a better kernel and OS will fix the problem.
Also tried the same game on S23U (same 8 Gen 2 chipset) and it ran as cool as a cucumber.
A quick google search does not net much overheating issues on the OP11 so I'm wondering if this is specific to my device.
Anyone suggestions as to how to alleviate the problem would be greatly appreciated.

80° cpu and 40° battery temp when you play
But let's ask how warm it is in your area (ask them because, for example, many people from India complain but do not take into account that it is sometimes 38-40c° warm in India, which means that the battery and cell phone in general are already very warm and thus much earlier the thermal engine throttles because there is not much air left)

This is in LA, so around 50-70 F or 10-20C. CPU runs at fairly okay temperature around 30-40C for normal day to day use (texting, redditing...). It's just a stark contrast from my OP8T or S23U since I pretty much don't notice those phones heating up but with OP11 I can consistently feel it gets warm.
My experience has been that this phone stays cool all the time no matter what I am doing.. Even Genshin maxed out.

Vapor chamber is used to spread heat. It is not some magic material which makes heat disappear.

Thanks for sharing! I was able to get my hands on a second OP11, ran brawlstars on it and the phone heats up almost exactly the same way with similar temperature measurements. Maybe the game is just poorly optimized on OOS13.
Also tried transferring apps and data over and CPU hit over 70+ degrees as well. Looks like the temps im seeing is normal unless somehow I got my hands on back to back defective units.

The best solution i can give u is to buy a peltier cooler i.e Oneplus 18W freezing point, Oneplus 11 has a very good passive cooling and with a good peltier you wont have such issues

thanks for the solution but dont think i do enough serious gaming on the phone to warrant a cooler. Just a bit disappointed and surprised at the overheating and throttling despite oneplus touting it having one of the better cooling systems out there. Since it happened on both OP11 I got my hands on, I'm going to attribute this to more of a software than hardware issue as other phones with same chipsets don't seem to have overheating problems.
