warm yes. very hot no.

Pretty sure it's due to the "liquid cooling" heatpipe in the phone, allowing the heat from the SOC to more efficiently leave the area, in turn, this leads to the phone heating up. The S9 and S9+ seem way cooler than Note 9, I've tried all 3.

apparently the s10+ (maybe others too?) also heats up pretty quickly doing mundane stuff( not gaming). looks like its the future.

Most likely. The Exynos 9810 is able to use 3-4W when it's stressed, that energy has to go somewhere.

Bad performance and other good/bad things (P10 Plus)

I have been using P10 Plus (6/128 GB) for a day, and I am trying really hard to like it. I haven't found all the good/bad points yet but the list of bad things is already kind of outweighing the list of good things. Were my expectations really just too high?
These are really just my opinions, and you are free to disagree. Even I might change my mind if there are really good reasons to!
I might as well add that paid about $860 (in Norway) for my P10 Plus while Galaxy S8+ costs "slightly more" (about $1,000). I just feel like I got so little in return for the price I paid.
I have to decide by tomorrow anyway whether to keep this device or return it, and I am currently leaning towards returning it.
Thanks for any tips, advices, opinions, etc.
Good things:
Responsive fingerprint reader on the front side, unlocks screen pretty much instantly.
Has a nice shape (like an iPhone 7). No annoying sharp edges except at the bottom holes for connectors, where I support the device with my pinky finger.
Lots of camera settings.
My device luckily has UFS 2.1.
Pretty good WiFi speed (measured more than 200 Mbps during internet speed test).
The DAC's quality is okay (not very good). A little bit of noise when using my sensitive in-ear headphones, but it's very bearable. This is only a "good" point because it's an upgrade from my old phone.
Bad things:
I already found some sluggish menus on day one.
Somewhat bad performance when taking photos and shooting videos, even playing back videos I captured is somewhat choppy.
The device gets pretty hot during "normal" (in my opinion light) use, and really hot while charging and during "heavy" (in my opinion normal) use.
Seems like the battery drains more quickly than I expected as well (larger battery does not make it much or any better than P10) so that I still need to bring an extra battery with me if I intend to use mobile data and GPS.
The swiping on the fingerprint reader is a bit of a hit and miss because it might register a tap which means "back" (or exit).
Photos taken and saved as JPEG look bad. RAW images look quite a bit better but it takes seconds to save each image.
My GFXBench result is pretty bad compared to other devices.
Nitpicking:
The edge of the screen protector is so annoying I want to take it off. Note: If you do it, you might want to apply oleophobic coating.
I wish the fingerprint sensor indentation was a bit less deep, because it makes the swiping motion feel less comfortable. The screen protector is probably most of the reason though.
I was never able to transfer app data (only apps themselves) from my old device using any method suggested by Huawei. The thing that did work was a backup/restore using adb.
USB 2 is pretty slow after getting used to USB 3.
The device sometimes thinks that I am using a knuckle gesture when I am using the tip of my finger.
sometimes very laggy also. And some apps not compatible with the camera.
Turns out that I am stuck with this device due to the shop's no-return policy on phones. I might as well begin training my mind to like the device. Won't feel guilty about rooting and trying custom ROMs now either.
@patriotzhou I think after a couple days, I am noticing the stuttering less for some reason..

Pretty much this phone is unusable due these 2 things, battery life is poor as AF, and from my perspective, Huawei messed up EMUI 5.1 really hard.
Probably an update would fix it, but we don't have ETA yet.
I will return back the P10 Plus because I think is not worth it, and I will buy a Mate 9 Pro that is virtually the same device, but battery life is so much better.
@nougn Which firmware are you on? In terms of battery life the phone may not be the best, but from my experience its also not bad either. 6 hours DOT should be possible unless you are a heavy gamer. However what you said about the device getting hot that does sound like it may have faulty hardware, I'd be careful with that. You should grab an app monitoring CPU and battery temperatures. If you come to the conclusion that the device is getting warmer than it should I'd contact Huawei on the matter. What I find most bizarre is that you say the performance is laggy at times, I never experienced even just the slightest lag no matter what I do, it is smooth as silk in every situation. Maybe another indication for faulty hardware.......? On a side note: the price you paid seems really high, a lot of commercial seller on ebay offer it for a lot less than that... but anyhow if you really wanted to get rid of the device you could always sell it on ebay or something, no? So you're never actually "stuck" with a device

This device always works in high temperatures, and is really easy for it to get hot. Use the camera more than 3 minutes and it will start to feel uncomfortable on hand.
I had the same experience, poor battery life and device most of the time hot. I checked the temperatures and is around 30°C on stand by, and after some minutes of WhatsApp and news, it was reaching 40°C, which is not normal at all, when my previous phone was around 18°C on stand by and 25°C in normal usage.
I'm used to stick with cold devices and is one of the first things I noticed when I used this device, and is a pretty common problem among many users. Most of the people would say that is only "warm", but I had the Mate 9 as well, with the same specs, and trust me, it was an ice cube the whole time.

One has to keep in mind though that temperatures like that are impossible to reach in summer (unless its a very cold summer), the device can never be cooler than the air surrounding it

Well, I'm talking about my room, which has air conditioning, and I just bought the P10 Plus and today I returned it back.
Problem solved, I got my money back, and I'm trying to see which phone to get, but pretty much I don' t like what I see in the market now.

The standby drain is crazy and as you said the phone gets really hot when using the camera more than a few minutes.
Also one more problem is when the phone reach certain temperature the wide aperture effect in the gallery will stop working..
It's a pity since I like this phone in many ways and the camera is great.
But if Huawei don't fix it (very) soon i may be "forced" to sell it and get another one..
Almost regret that I sold my old Mate 8..

Today I returned my P10 Plus, for me there's no excuse to pay so much for a phone that has basic problems.
I will see if I get a Mate 9 Pro or any other phone, but I'm kind of picky when getting a new device.

Thank you for your advices! The current version is VKY-L29C432B150 (latest).
Sorry for the late response. I have been traveling for the past few days.
I decided to bring this phone with me on vacation to Japan where it is currently very humid and it feels like 33+ degrees C (91+ degrees F) in the sun. Trying to use mobile data, GPS and Google Maps is not exactly pleasant for my hand. The worst part is trying to take some photos because the device's temperature gets uncomfortably high for my hand. Will try to measure the temperatures next time I go out!
I am also really glad that I brought an extra battery, although the output of the extra battery (per port) is just enough (2.4A) to keep the device's battery percentage stable while using mobile data and GPS (goes up when idle).
I also guessed hardware defect, but it now seems like I am not the only one with problems. I really hope that Huawei can fix some things in the software, including the heat issue.

You should post your experiences in the battery thread, so it could have more visibility and people can start to acknowledge this, would be really nice from you to do it.

Different screens
The P10 plus has a IPS LCD screen
The Mate 9 pro has a AMO-LED screen
maybe that adds to the difference in SOT for the two Huawei devices...

That's how you choose to read my post - but not what I wrote, IMHO
My point is to raise awareness about the different screen technologies, because I've seen more than one comparison where the two devices are said to use the same screen (probably because of same size and res.), but that is plain WRONG!

I understand your point, but still having AMOLED display means nothing in 2017. You can see the HTC U11 with LCD and has pretty goddamn battery life. You can have the normal Mate 9 with IPS and also has a really nice battery life. Right now screen technologies are really mature and it doesn't influence much (or at all) what kind is on a phone.
@Galaxo60
Point taken
Came from S8, I used it for a couple of months and now Im using P10 Plus.
Im more than happy now with P10+.
I have had my P10 Plus for about 2 months now and I can tell you I get around 5 hours of SOT with 1-2 of gaming. The battery stays at 100% for about 15 minutes regardless what I do and then begins to drop. Somehow form 70% downwards it starts to really slow its discharge rate. You might worry about this but the honest truth is that I can make it at the end of each day (around midnight) with around 15-20% battery left. For me this is more than enough as I recharge my phone every night.
I would suggest you stop worrying about your phone dying on you and just start using it. Also use Phone Manager once a day and you'll be good to go.
Hope it helps.

Question S21 Ultra Snapdragon Always Running Warm

Simple use of the phone - browsing, instagram, google news, whatsapp, etc., the phone gets warm. Playing PUBG for 30 minutes, the phone gets a lot warmer, but never hot to the touch. The only way it stays cool is if I'm not using it at all. In comparison, my OnePlus 7 Pro stays cool all the time, except when playing graphic-heavy games.
Any setting I'm missing?
Welcome to the hot club!
That's odd my s21 ultra stays cool barely warm when gaming
If you have the Exynos version of the phone, then that could explain the heat. But if you have a SD888 variant, then your phone will still get a little warm, but not quite as hot as the Exynos.
Using GSAT to check temperature levels, any light activity gets the phone to about 36C to 37C. I tried restarting the phone about 5 times in a row and it went to about 44C.

Thanks for updating your post title =). That's the clarity we need for this phone on XDA.
Anyway, I'm unsure of this, but I'm pretty sure that when a phone is booting up it generally creates a tiny bit of heat because it's just getting everything initially setup for that boot.
But yeah, just be glad that you have the SD version. If you didn't, it might be even hotter! And I agree that this phone still gets pretty warm - I just haven't done any temperature tests on mine. Either way, do you happen to be using a case on this phone? I'm a caseless phone user and my phone still gets warm when used for an extended period of time... So I have a feeling that some thicker, heat sealing cases might be turning these phones into toasters...
*Edit* - maybe they'd be more like hand warmers? Lol

Coming from a OnePlus 7 Pro, the heat generated during light use is so noticeable that I had to install a temp monitor (gsat). No problems with previous phone.
I have the official leather cover on, it may contribute to the heat but it shouldn't be that much, I reckon.
I don't need hand warmers haha.

Please take a 10 minute 4K30 Video and say how much % battery it drained and if the phone got hot.
I also have the Snapdragon version and I'm not sure if what I'm experiencing is normal or not, but my phone gets warm often especially the aluminum on the top left opposite of the camera. I've been keeping track of the temperature and it seems like my phone is always operating around 33C - 35C on normal everyday use like browsing, instagram and youtube. When I use the camera it goes to almost 40C. These numbers are around 91F-95F and 104F respectively. I recorded a 3 minute video on 4k60 and that's when it hit around 40C. Really trying to figure out if I should do an exchange.

Exynos: Lost the same 5% as you reported, and phone got hot around the camera module. Temperature of surrounding environment was around 20-25 degrees celcius. The phone didn't feel especially hot in general otherwise (using a relatively slim case).
Losing 5% in 10 minutes means about 30% per hour. So one could record in 4K for about 3-4 hours straight? Is that really that bad?

Yes it's bad in my opinion. My S20+ (with the infamous/bad Exynos 990) lost 5% in 15 minutes 4K30 video recording and got barely warm.

Yes, that's what I thought. I'm coming from the S9+, and there were several issues with that too when it first came out, which were all fixed with subsequent updates.
Just curious, how do you find the recording in FHD60? That's been my default recording as I don't actually have any 4K monitors.

Just thought I'd update here - re-tested with the April update. Lost 4% in 10 minutes on 4K30 video recording this time. Heating not as bad, although that's simply guessing/subjective (I don't have a heatgun).

It's just natural to lose 4% in 10 mins of 4k30fps recording. You are basically using all the system resources when operating the camera - i.e. the CPU, RAM and storage all run at the highest. It's not just this device you test this on any device iOS included and the results will be almost the same.

General Snapdragon 888 vs Exynos 2100 after latest updates

I know there are already a few threads for the same discussion ,
But I am making this thread for a healthy discussion on what's better between Snapdragon 888 and Exynos 2100 after the latest software updates for both models .
There are youtube reviews that are contradictory to each other
1) Mrwhosetheboss says Snapdragon is way better and Exynos is heating like crazy.
Also in camera sd>exynos
2) The tech chap on the other hand says Exynos to be faster and cooler .
Let's discuss
I am planning to buy the s21 ultra over the OnePlus 9 pro just because I am getting it at the same price as OnePlus 9 pro ,
Also the software on OnePlus is always going to be buggy and an update to fix one issue will create more bugs .

After my experience with the Exynos, I'm far more inclined to believe the Tech Chap. I've had no issues with thermal throttling, and my phone sits most of the time at between 28 and 32 degrees when being used under normal circumstances (browsing, light camera use etc). I've also run the benchmarks he ran and got pretty much the same results. I'm very happy with it.
I strongly suspect that boss geezer just had bad luck and picked up an Exynos model with a bad SOC. The difference between the two is he didn't buy another to rule that out.

Like both Youtubers in this thread, I'm in England so it's not hot at the moment.
Ambient temp makes a difference, but my experience of mobile phones in the UK over the last 25+ years, not massively so.

You say even Apple iPhones but they're dogs**t when it comes to thermal dissipation, in particular the more recent ones.
All I can say is that this phone is no worse than any others I've had when it comes to thermals, and seems to be better than most of them.
After I contemplated a lot, I went for it and purchased the EXYNOS version as I live in Europe and the Snapdragon seems to be Single SIM, so no point ordering it from Amazon.
Mrwhostheboss either had a faulty unit or at the time of his video, the update he put wasn't enough to fix the software issues.
Mine works fine, no overheating (gets a bit warm when doing heavier tasks, ~22c ambient room temps), no camera problems or glitches, all seems good. The camera quality is pretty fine too, although it did definitely improve further after I installed the last update. When I tested the camera out of the box, it was all weird.
Battery life for me is quite fine as well. At the time of writing this message I got SOT 1h45m and battery is at 78%. Plenty of apps installed, Dual SIMs active. AOD active.
I also have the Dr. Ketan ROM with root, AFWall and etc. So I slightly debloated the useless stuff.
I am satisfied with the EXYNOS, and although I have no way to test them next to each other, I'm sure that If the SNAP is better in some ways, it is NOT in others, like NO DUAL SIM.... And for sure if there is anything left to fix on the EXYNOS, they will fix it with the upcoming updates.
But again, if you buy an EXYNOS, make sure you do it right. Start it, install all your apps, make sure you update it to the latest firmware version and then start testing it. If it has problems, factory reset it and return it for a new one.
Good luck!!!

In india there is nothing as return ..
Once paid the device is yours till it has some major issues and they are just repaired ,
Unfortunately We cannot return it for a refund here in india .
That is why thinking twice before buying .
I have no overheating problems with my Exynos unit. Phone idles at around 25-30degC.
Yo bro,
Listen, avoid YouTube reviews. Bro these ppl are just benefiting from these kindda arguments and stuff.
I had the s21 ultra 512 and i sold it coz i have literally watched every single review out there and was too worried i might have been scammed or made the wrong choice.
After talking to some ppl here i bought it again and this time i made sure i cleared my search history lol and never ever to watch a thing.
It is not SD888 but it is close, it has good battery, cameras are barely any difference between them. If you game a lot you should really just buy a different phone just for gaming.
The screen is phenomenal.
Bro i live in Kuwait, temps here reach 55°....until now i have not experienced any extreme heating issues.
My advice to you, don't listen to anything, the device is amazing...yes it lacks behind the SD888 but for me it's the better pick.. i get warranty for a year and a trade on later or i can even sell it and not lose while the imported is basically non sellable here.
So weigh things out and decide, once you decide do not regret. Do not hesitate it's just a phone, if you have a slight doubt avoid it and wait for a different phone.
Goodluck.

I know there are already a few threads for the same discussion ,
But I am making this thread for a healthy discussion on what's better between Snapdragon 888 and Exynos 2100 after the latest software updates for both models .
There are youtube reviews that are contradictory to each other
1) Mrwhosetheboss says Snapdragon is way better and Exynos is heating like crazy.
Also in camera sd>exynos
2) The tech chap on the other hand says Exynos to be faster and cooler .
Let's discuss

Camera has improved on the exynos with updates, personally I still feel low light video and photos are just ok, but anything in decent light is great, and I don't have anything other than a pixel 3 to compare to, so not a fair fight as the camera tech on that is old.
In regards to the video, mr whos the boss was using antutu for temperatures and it's well known that at that time it couldn't read exynos temps properly. When I had antutu, it showed around 40 degrees, but CPU monitor was around 25 degrees
I've got the exynos and had no real issues to date, battery life is sometimes great, sometime ok, but more than enough to do me from morning to night with my usage. Other than that can't complain at all
Should wait for the xiaomi's launch today?

That temp thing with Antutu makes sense, I was worried when I first got my phone as it was listing my CPU temperature in the low 50s but then I installed CPU Monitor and it showed it was around 30 degrees. Maybe MrWhosTheBoss should have done a bit more research.
It's funny reading the comments on that video. Thousands of people talking about the S21 Ultra being rubbish on Exynos without having the first clue what they're talking about. It goes to show how a badly made video can really effect how a phone is perceived.

Exactly and there is me researching this from a week before buying it .
Also tried to stress the camera on the demo unit at a samsung store , but it was warm to touch but not at all hot ..
By the way , as OnePlus markets their 9 pro with 5 layer cooling system , how's the cooling on s21 ultra?
JerryRigEverything did a teardown, but it's the SD varient. I'm not sure if the cooling solution on Exynos differs.

The Samsung is much more aggressive with its thermal throttling than the mi 11 (A good thing or a bad thing depending on what you want in a phone), don't know about the oneplus or how effective it's cooling system actually is (could just be a gimmick/branding, but I don't know).
I would say from what I've seen, s21u has better battery, genuine adaptive refresh, marginally photos cameras but much more versatile camera array, better software.
Mi11 better charging and sustained gaming
Early oneplus reviews have middling battery life, but an educated guess that they haven't enabled the variable refresh yet on the pro, as it seems to last the same amount of time as the base model.
In all honesty, if you aren't sure, wait a month or so for the 'long term' reviews, then you will get a better idea of the final product

I am getting the s21 u e2100 today .. let's hope I get a good silicon compared to what some people have got
I seriously have a feeling that both versions of the phone are nearly identical in performance and camera quality. The primary reason why we see so many threads regarding heat issues, app crash issues or battery issues are not necessarily due to the versions of the phone that are being used (Exynos or Snapdragon)... But instead, I think that this is mainly due to the fact that a lot of Samsung's phone sales are to people who aren't very tech friendly....at all...
I mean, think of Apple's iPhone market. What percentage of their customers are tech geniuses who know everything about complete device care and optimization? I'd say, near me in the US, maybe about 3-5% of their customers... And with that said, you have to keep in mind that Samsung is the most Apple equivalent company in sales numbers for Android devices in the US. So probably only about 1-2% of their phone customers actually know what the heck they're doing.
So (internally thought lol) truth be told, I don't think one variant is better than the other. I just think that we need to keep in mind the fact that the Samsung phone market is packed to the gills with customers who don't know much at all regarding the technology that's used or how it works/can be optimized or made better. Luckily for us on this particular thread, we probably don't run into the aforementioned issues as we're likely all people who actually know how to use, care for and optimize a damn smart phone lol.
Side note: this was a long comment, so my apologies.
*Edit* - To respond to @aj7400 without wasting more post space :
The US isn't really a particularly cold area. It's just a much bigger area. So there are certainly some states where the temperature stays cold for a while... But there are tons of other places where it stays over 23°C all year round (and a few states where it stays above 33°C all year). So overall, I still believe that these issues are just coming up due to a severe lack of knowledge =(. But the good thing for you is that you actually appear to know what the deal is, hence why you're here on XDA. Thanks for being here =). But ya see what I mean? You were aware of the slightly warmer temperature of the S21U and you were aware of the fact that you live in a hot area. Therefore, you're not constantly complaining about the phone being borked out of the box, but instead, you're looking for potential solutions. Kudos!

That's allright ,
But imo apple is from day 1 producing good chips and their optimization is top notch ,
And samsung in US is just offering Snapdragon .
That's the main reason people are not complaining about both , and they don't care what are the specs in their phone .
Also US is a relatively cold area so not much is going around throttling issues .
I live in india where highest temps reach 45°C , where the real problem of thermal throttling arise .
So I care much about these things .

Question Oneplus 9 pro crushing iphones in speed tests

I know this topic doesn't makes a sense here ,
But since we all have paid more than the price of one plus 9 pro ,
We can atleast discuss the still lacking and poor optimization from samsung ( exynos 2100)
I opened the camera app in sunlight today and the phone was getting a bit more than warm , (42°C) .
Check the video and enjoy
Lol, don't be surprised if OP is faking tests. OOS is buggy anyway.
Exynos version of S21 is also well optimized. Maybe u have an specific issue?
Um no specific issue , just comparing the app opening times , it's faster on oneplus 9pro
I have just one issue , my s21 ultra is sluggish sometimes and remains warms to touch whenever I use it ( basic use like typing this comment)
My ambient temps are 35°c

My SD S21U also always running warm, even after the 1GB recent update. Hopefully this is something that another future update can fix.
That's due to the heat sync design I think.
It's pulling all the heat from processor
The metal frame all around is at similer temperature , where as on my previous phone only a part of phone used to get hot .
I think that is because of excellent heat dissipation.

Quite simple...steps are here: https://forum.xda-developers.com/t/...-04-mar-21-galaxy-s21-ultra-sm-g998b.4218529/
But you need to be careful to have a stable USB connection as my computer decided to reset the USB port in the middle of the flash! Thankfully, I could revive the phone by Odin flashing the device from another computer and via a USB 2.0 port. It's dead slow but at least sure.
Odin reset is the best solution to all sorts of heating/ battery issues. It's not the same as factory reset as this only cleans your data partition. Odin, resets all your partitions thus making your phone back to the same state as it was when it rolled out of the factory line...

Samsung S20 FE Overheating

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.

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.
