I really hope Samsung fixes this "issues".
It sucks. Hard.

What is the problems with the exynos processor this year?
You think software issue or harware issue?

Whats wrong with Exynos cpu. Well it is the tortoise and the hare.
Intel speed shift it is not.

Exynos 9810 seems to be another 5410: made to impress in synthetic benchmarks, and stop at nothing to achieve that.

I will take this review with a grain of salt....agreed most reviewers don't go so deep and basically review their devices after a week of daily usage....but still if the problems were so deep..it would have been reported.
Like i said in the comments there, i believe most of the deductions from that test will not impact your day to day life. Information is great, but one must know when you need a "summary" and when a "thesis"
I am still buying this beauty next month and i am sure i would be satisfied.

Ive heard reviewers say and show on video the exynos having better battery life and a faster processor. Who to believe? I returned my snapdragon for an exynos because my SD got such horrible battery life. Just got the exynos so we will see. At least it can have root.

Grain of salt? Did you even read the review?!
Sure, Exynos this year will still feel smooth, just like it did last year; but there is no denying to the fact that Samsung is still not up in its game when it comes to GPU efficiency. Samsung will still need to tune the scheduler on this Exynos (if not already tuned with March update). And unlike those most phone reviews out there, Anandtech folks actually go back and update their reviews after substantial changes that manufacture might have made (AT also reports those suggestions to OEMs when they review).
Anandtech is one of the few tech sites remaining that review hardware like how hardware should be reviewed.
Do not dismiss such hard work just for the sake of sounding edgy on the internet.

I had the s9 for 10 days, sold it because I got much worse battery life than on my nearly one year old s8 and there were nearly no improvements at all. I only noticed these 3:
1. fp reader, better placement and much more accurate.
2. Sound from speakers which i never use, much better.
3. dual-sim.
In the end i felt that selling the s8 for 400 dollars more than I would get for my s8 was definitely worth it. Very happy with that decision.

As i said , such reviews have no real benefit for me as a everyday consumer. There's nothing to say that the author hasn't done an excellent job...he has. Point is whether you need such deep analysis , when you are never going to be affected. My view is <1% will notice these things.
Secondly battery is a very subjective thing, it depends on user to user and companies generally take a month or two to fix their stuff after a new release.

So I've had the exynos s9 all day and I gotta say it's much better battery life than my snapdragon s9. Only problem is now LTE doesn't work. Ughhh.

Even with a Exynos cpu, it will has godly performance.

Yes it's in depth but not always how it really is.
Look at his benchmark charts and realize that SD835 is almost every benchmark faster than Exynos 8895 and 9810. Well, we all know it's not the case in real life.
Apple's A11 is fastest soc in every benchmark but in real world iPhone 8 is nowhere faster than Android flagships depending on sort of apps you use.
Never trust benchmarks only. User experience is more important.

Those are not benchmarks; those are to test specific aspects of a SOC.
SD835 does still beat Exynos 8895 and 9810 when it comes to GPU intensive tasks; that is to credit QComm's exceptionally mature Adreno architecture.
SD835 will continue to beat these 2 CPU's when it comes to performance per Watt due to that.
SD810 was a failure, SD820 managed to narrow the GAP with E8890, and SD835 more or less went head to head with E8895.
Sure, synthetic benchmarks still favoured Exynos year after year, but the reality has not been that clear due to Samsung's DVFS being a year late compared to QComm. Those things might not be relevant to how a device performs (due to difference in choice of system variables and tuning); but they are very much relevant to judging how those SOC were designed and implemented. That is what the point of those tests are (over AnandTech and for their usual style of reviewing stuff).
You can check speedtests on ytube for SD845 vs E9810 and decide for yourself (speed tests are usually dumb across different devices but you can make some relevance when it comes to same device with different chips).
One such example:

AnandTech has published a testing article here for those of you who have been following this discussion and/or interested in improvements that Samsung and/or developers can bring to Exynos S9/S9+ via kernel modifications.
Improving The Exynos 9810 Galaxy S9: Part 1
Interesting read.
TL/DR:
Today’s results are just meant as a quick preview of the Exynos S9’s behaviour when removing what I believed the most offending parts of Samsung’s mechanisms. The results are very promising as we are essentially getting real-world performance boosts while at the same time seeing efficiency improvements and battery life improvements.
There is still a lot to be done - I haven’t really touched the scheduler or DVFS scaling logic, but I’m confident that it’s possible to improve things further. It’s unlikely that we’ll end up matching the Snapdragon 845 variant in battery life, as there are efficiency curve considerations at lower performance points that simply cannot be changed through software. But closing the gap as much as possible seems to be an attainable short-term goal.

Now Samsung chimed in on the issue
https://www.androidcentral.com/samsung-addresses-battery-issues-exynos-powered-galaxy-s9

I'm extremely intrigued but also confused at the same level. I ordered a regular S9 Dual-SIM after reading reviews and reports that told me it was a great device and a nice upgrade from my S7 Edge. Then I cancelled my order because I read that a lot of people with the Exynos variant have battery related issues. Then I kept reading and noticed most of these reports where from devices just a couple hours or days old. The more recent reviews seem to show a different picture. While still a mixed bag, battery performance seems to be much less of an issue in more recent reports. For some it's even better than their previous devices. The reviews/reports who seem to praise the performance (battery) the most include almost exclusively people who compare it to the S6 (Edge), S7 (Edge). So, I placed my order again for a Coral Blue S9 Dual-SIM. Don't care for the Dual-SIM but somehow it's the only variant available in Germany. Whatever.
This is by no means an accurate analysis of the current or past situation. It's my experience. It's not representative in any form or function.

The upgrade will be very notable over s7 generation.
S7Edge gave me great battery (6-7hr SOT); S8 and S8+ gave me lower than that (4-5hr SOT). Now S9+ again gives me great battery (6-7hr SOT).
All of them have been Dual SIM models; and yes, I did change phone that often since I had a way to upgrading for a very small price difference.
S9+ upgrade wasn't as cheap for me, so I'll have to continue on this for a bit longer. It is an exynos S9+ from India; and performance has not been an issue so far for me.

I had the regular s7 before and upgraded to the exynos variant s9, and it is true that battery life during the first week or two is not adequate. Battery life has improved much and overall it's still a great device compared to other devices out there. Yes, I do wish the battery capacity is larger and Samsung do further optimizations to get battery life on par with the snapdragon variant it isn't the worse and I'm able to get a full day out of it. Honestly if you can wait, wait for the s10. The new 7nm chips and rumored higher battery capacity should make a killer device. But you can't go wrong with the s9 believe me. Other devices out there are flawed one way or another and the touchwiz experience is honestly approaching perfection, yes it was terrible years back but now it's way better than stock android in my opinion.
In the screenshot below, the power saving mode only has decreased 10% screen brightness only. No other altered settings.

This is what I'm talking about.
Battery tests, even in-depth semi-scientific analyses are all over the place and inconclusive. It is true that battery life is very user dependant but there should be a common theme all across the board. However, I don't see anything like that. I can't dealt with this for 2 years. I cancelled my order and will wait for a better deal on the S9+.

So , it seems , my reaction to the anandtech review was spot-on. S9 , irrespective of the cpu variants, is still a great device and we must not confuse ourselves with too much information where none is reqd.
God willing, I should be getting my hands on the s9 in early May.

Anandtech review of the S9/S9+ shows S845 is much faster than E9810

Very interesting read!
https://www.anandtech.com/show/12520/the-galaxy-s9-review

If Samsung doesn't fix this I'll sell my S9

Really wanted to buy one but I'm not going to as long as this issue is not fixed.

Fix what? It looks like any performance "fix" will be accompanied by loss of battery life anyway. There is a slim possibility that scheduler/governor could be improved somewhat, but that will not change the underlying hardware characteristics that much, meaning the gain from such a fix will not be significant and you will still pay a hefty battery cost..

Like i said in the comments there, i believe most of the deductions from that test will not impact your day to day life. Information is great, but one must know when you need a "summary" and when a "thesis"

Whenever a load is transferred from LITTLE cores to the big cores, SD845's big cores start at the max frequency while E9810's big cores start at the lowest frequency (and then increase gradually if load continues to be active).
If the load is of a longer nature (beyond 450ms iirc) then E9810 wins the race; but for short and burst loads the SD845 wins the race due to starting at max frequency.
So no, scheduler fix will not improve just somewhat; it will improve the performance substantially.
Sure, that might come with a battery hit since it will be a choice between 'a longer running load at lower power' vs 'a shorter running load at high power'; we will know better about battery drains when we get results from having used such a scheduler.

The way that exynos takes that long to ramp up the cpu, its like the only way one ever gets to 'experience' it in full speeds is synthetic benchmarks.

I was pumped coming from Snapdragon devices and thought the general consensus was that Exynos chips were typically better than Snapdragon. I'm saving to buy the Exynos version, but then a few of the big Youtubers ran speedtests of SD845 and 9810 and it seemed like the 845 generally performed better.
And after reading the anadtech article and battery life being worse (which is huge to me because I want the regular S9 and not the plus) I guess Snapdragon all the way.

I think general every day battery life depends on a lot more than just benchmarking. I have both the exynos and snapdragon S9 with me right now and the exynos gets better battery life after 1 day of use. I just got the phone yesterday but both starting with a 100% charge and using both pretty equal amounts and doing testing and web surfing etc... my exynos has about 10% more right now. Driving to work yesterday my SD845 phone drained 14% with the screen off and not even music playing. Honestly coming from a Pixel 2 XL they both kinda suck hard on battery life. The SD version was dying in half a day of light use for me. I got through the rest of the day yesterday with the exynos which is doable but ill have to keep chargers all around to make sure it stays charged on heavy use days.
Edit: On a side note if you decide to get the exynos and you use T-Mobile you may want to wait because I get horrible reception and slow internet speeds. I dont know why sicne it supports every band for LTE except 71 but the snapdragon version is significantly better and much faster on tmobile network. Maybe there are settings I can change. IDK.

I would really like to have Band 71. I thought I saw a post from someone who was getting conflicting answers from Samsung if B71 was in the international unlocked version. However then he posted and said he received it and sure enough found B71 in it. But now it's looking like I'll just bite the bullet and get the T-Mo SD845 version. Would have be nice to have an unlocked bootloader.

How can you find out if it has Band 71 on it? I can test side by side my US and international verison and the US version gets about 30-40mbps and right beside it is the international getting about 1.5-3mbps max. Soemthing is obviously wrong with the settings or the radio on the international to be doing that bad on tmobile. Its not bad location. Something is just missing either software, hardware or settings but I just odnt know. Id love to make this thing work.

You'll have to look through the forum here. I have other things going on, but I remember someone created a thread and stated that it did. I have no further info.

Well, it's not like the phone is slow in any way so stop making a chicken of a feather.

I've been holding out on an upgrade for the S9, but this is concerning (I use T-Mobile).
Snapdragon is a non-option for me as having proper backup (aka Titanium) is IMO a bare essential. Now after having seen reviews that the S9 Exynos' battery life is even worse than the S8's, I'm wondering if I should just get the S8 instead. Anyone have any thoughts - S8 Exynos or S9 Exynos? If that Anandtech article's results are at all representative of what to expect, does it not seem silly to pay more for a newer phone that's a *downgrade* in battery life? Or maybe I just need to wait a bit longer for the kinks to get worked out? I mean, if it can really only do 1.5mbps on T-Mobile...ummm....

Ok well I did so many things to try and fix this and SOMETHING worked. Im now getting pretty much full speed although still not quite as good as teh US version for some reason although very very close. I went to Tmobile and got a new sim card in case this one was damaged or soemthing. i also played around with the APN settings and restarted several times. Something jolted the phone into working. SO when I test the two phones side by side now the US version might get 21mbps and the international 18mbps. Again the US will get 31mbps and the international 26mbps. US 13mbps and international 11mbps. The US version is always just slightly ahead. I drove around town and found some low reception spots where the US version was getting 2mbps and the international was crawling at .65 mbps. Out of probably 30 different test I did driving around I think only 1 time the international got better speeds and it was like 31mbps vs the US getting like 28. Id say its usable for sure but here is where it might matter most. I was in a bad reception part of town in a big mall type building and I rarely ever get service there. You have to stand next to a window to get any bars at all. The US version could barely get a connection but it did get something. The international didnt see anything until I completely left the building. Coming from a google pixel 2 XL that phone was about the same as what the US version of the galaxy s9 got. I walked all around the building and saw similar results. We dont even have band 71 in my city and that is the ONLY band that is missing from the international version that I have. Theoretically the international version SHOULD be performing the same however ive done plenty of test I can pretty much say in my case the international is slower.
Ironically the International version has been killing the US version in battery life. Im very happy about that. In standby mode the US version seems to drain very quickly for me while the exynos seems to just barely sip power. I can go an hour in standby and only use 1-2% while the US version can easily use 8% just sitting there and not doing anything. This morning I woke up and cleaned the house and both had 100% when I started. I didnt touch the phones at all. Both on wifi. About an hour later the exynos was at 98% and the US was at 93%. Both phones have the same apps and theoretically the same services running. The international actually SHOULD have more running in the background since my allo accound and texts/calls go to that phone and my wifes sim is in the other phone.

Damn, that's definitely an issue, especially since I live in a very low-signal part of town (in the mountains). I wonder how Exynos S8 vs Exynos S9 does in this regard...or if anyone else has any similar experiences as you...

Super odd, considering that's the exact opposite of what all the reviews seem to be saying! I'd be curious if anyone else could replicate this result - or again, to see something similar with Exynos S8 vs Exynos S9...
One more question: have you been able to get T-Mobile Wifi calling on the Exynos S9? I'm guessing not, but here in my low-signal area that's pretty essential. I figure someone on here will eventually work it out, but I was just hoping it might somehow already be up & running

I agree the battery life thing is very odd when you look at the word around town about the exynos. I think all that talk is sparked by the Adandtech review of the two phones and what you have to consider is those are synthetic benchmarks and they were also dealing with the snapdragon S9+ and the exynos S9 so completely different screen sizes and battery sizes. Now they used the cpu efficiency to come up with this idea that the exynos would theoretically perform worse than the snapdragon but thats all synthetics. I saw many online reviews of the battery life from the exynos and snapdragon versions and compared them and took a leap of faith that the exynos would be better. That was before the anandtech review came out. Thank god I was kinda right because battery life could not have been worse than my snapdragon s9 which just seemed to kill battery even when screen off and idle. Maybe its just my unit was bad but who knows. My review of battery life is strictly based on normal every day use and not synthetic benchmarks that nobody just does all day every day. Benchmarks are nice but they dont do crap for how you actually use the phone.

For me that particular comparison is irrelevant, because a Snapdragon is non-unlockable -> non-backupable -> non-option. I was concerned about the results showing Exynos S9 is even inferior to Exynos S8.
And I agree that every-day use is what matters, not synthetics. However, I would also assume that synthetics would have *some* correlation to real-world; obviously they aren't a perfect representation of it, or they may exaggerate the difference, etc. But it's pretty surprising to find the exact opposite result. Makes me wonder if the S8 vs S9 result could be backwards too...

Give me an exynos over a snapdragon anyday.
Im more than happy with a small loss of performance over not being able to unlock my bootloader and customize to my hearts content.
My s9 plus is a very good upgrade on my s8 (now with the wife)
Im not even going to read this article as its a moot point tbh. Real world performance wise, this phone blows anything else i have used out of the water.
Yes with both battery and performance abd despite it being an exynos lol.

Performance is excellent with my galaxy s9 it's just battery I wish was better.

Question Is it worth to upgrade to a snapdragon 888 considering these ?

i currently own an S21 Ultra Exynos 2100 barly can reach 535k in antutu and poor score on pc mark and others and overall performance even if you freeze the phone and tried factory reset and it tried it all ... even battery life seems weak video play back barly six hours whatsapp calls drain it like its furmark on pc something is messed up with my unit and i dont wanna go through warranty here cuz ill be without a phone for several months and new ones will be out and in the end they will say its not covered so should i just pay difference import snapdragon 888 sell my unit and upgrade considering camera upgrades ai score upgrades etc and all other benefits to gpu boost ?
thoughts ?
live in middle Beirut warranty is just a word nothing is guaranteed everyone will try to rip you off basically
hope this isn't repeated but feel its a unique case considering the conditions and geolocation

What is your current build number?

i currently own an S21 Ultra Exynos 2100 barly can reach 535k in antutu and poor score on pc mark and others and overall performance even if you freeze the phone and tried factory reset and it tried it all ... even battery life seems weak video play back barly six hours whatsapp calls drain it like its furmark on pc something is messed up with my unit and i dont wanna go through warranty here cuz ill be without a phone for several months and new ones will be out and in the end they will say its not covered so should i just pay difference import snapdragon 888 sell my unit and upgrade considering camera upgrades ai score upgrades etc and all other benefits to gpu boost ?
thoughts ?
live in middle Beirut warranty is just a word nothing is guaranteed everyone will try to rip you off basically
hope this isn't repeated but feel its a unique case considering the conditions and geolocation

If you can return it do it and get 888, if you can't return it's not worth to sell and lose more money just to get another version, the phone is already too expensive

Probably not as much the cpu as crap running in the background robbing battery life.
This is true on the Snapdragon variants as well.
Android Q sucks due scope storage robbing cpu cycles/battery and more restrictions on 3rd party apps making diagnostics harder than with Pie.
My AT&T Note 10+ was a battery hog until I toned it down. It was time consuming to do but today it runs very well.
If I had to replace it today I go with another 10+ running on Pie. A vote of no confidence in Q/11 as well as Samsung's lack of newer/substantially better flagship phones.

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.

I live in a area where the temperatures are like 40°C for like 8 months and 10°C for 4 months ..
At 40°C ambient temps even apple iphones break their sweat and throttle.

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.

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 .

General To all exynos s21 , s21+ and s21 ultra users

Why dont we all gather , and file a complaint against samsung for intentionally clocking down and throttling the exynos 2100 against the sd888 even when exynos 2100 this year is capable , comparable to sd888 and moreover both are manufactured by samsung?
Samsung is again giving us an inferior experience in other markets vs US while charging similar / More
Lets complaint on twitter by tagging @samsungexynos and also on samsung members app ,
If you have any other alternative please comment down.
These 2 videos are the proof .

I disagree.
It'll be another 1-2 years before the Exynos can catch up to the SnapDragon.
The SD888 is more or less, IMO, comparable to the A14. It took a while for Qualcomm to catch-up.
In another 2 years, I expect the Exynos, SnapDragon, and A series to be more or less comparable.
Then, the game will heat-up in the laptop/mini-PC/server space.
You'll have to wait.

I can say that all those speed tests are meaningless.
I have Exynos and I am satisfied with everything so far.
Yes this year Exynos is not the same as SD888 but it is not behind by much compared to last year competition between exynos and sd and next year will be a gamechanger for Exynos since it is getting AMD gpu and improvements.

We all knew even before we bought the phone which processor it came with, in which country. Samsung did not say they were selling the SD888 in my country and then hand me an Exynos.
Also, nobody put a gun to my head and asked me to buy the phone. It's an open market and there are a hundred options available.
Exynos performance is not some breaking news that we just found out. We have seen Exynos processors for years on other phones, including last year's S20 series and know perfectly well what they are capable of and what the limitations are.
Despite all the above, if you still went ahead and bought the phone, it's on you. You knew perfectly well what you were buying. OnePlus 9 Pro was also available with the SD888 globally. You don't buy a phone only for it's processor. There is a lot more that goes into making a phone.
Personally I think the S21U (I have the Exynos) is the best phone I've ever used. Spent a week researching it before i bought it, used it in the showroom multiple times before dropping this kind of money and despite all the YouTube comparisons, decided I liked it more than the other available options and bought it. And I don't regret it.
Monopoly is bad in any industry and I'm glad there is another manufacturer challenging the dangerous dominance of Qualcomm in the Android arena. Exynos 2100 may not yet overcome the SD888 in terms of raw power, but it has narrowed the gap more than it has ever been. And it runs much cooler than the SD version, plus has significantly lower standby battery drain.
I'm not a Samsung fanboy, I dropped them and shifted to the iPhone and OnePlus after the Note 3 when their software was getting crappier with every update. Returned back only after I was convinced that OnePlus was on a downfall and Samsung software had improved over the years, and also that the E2100 was worth my money.
If you think Samsung is selling a "bad" processor in your country, speak with your wallet and don't buy it. Simple.
There's no point getting angry and ranting after buying the phone, knowing very well what you were getting.
Why do you think Samsung or any other company will change anything if you keep giving it money despite disagreeing with its policies?
Rants don't change a company's practices, the balance sheet does. For the next few years, don't buy Exynos. If enough people agree with you and do the same, and make a big enough dent on Samsung's profits, maybe they'll listen.
Otherwise all this petitioning business has been done countless times before and is a meaningless waste of time.

The exynos story is over exaggerated. I owned albeit previous gen tech a note 20 ultra in both exynos and snapdragon. They were both fine battery life and temp wise. Alas I didn’t game though.

Never judged much on speed tests on the internet. Real world usage is far more important

Well you might be correct at what u are saying .
My point is , this time exynos and sd888 are both manufactured by samsung using the same process and same cores.
Its just the calibration of cpu thats not unlocking the real power of exynos 2100.
All the tests show that exynos is continuesly throttling its cpu.
The large performance core which is supposed to be clocked at 3 ghz is always throttled to below 2.2 ghz even when the phone is cold.
Where as on sd888 the large performance core remains fully clocked at 2.9 ghz even after heating

I read a lot about the Exynos issues with the previous Samsung devices and was well aware of the possible difference between two versions of the S21 Ultra based on SD vs Exynos but in the end I got the phone anyway knowing I would get the Exynos version. So why is that Samsungs fault?
Also, I notice more heating issues are related to the SD version so maybe that is because SD is less careful and more aggressive about being the fastest. I have no heating issues and I can do everything the SD version can and as fast as I could possibly want. I do not see any performance issues using the device.
You had a choice to get the phone or get something else. It gets tiresome seeing posts "I bought this phone and I don't like X,Y and Z about it", nobody forced you to buy it.
And Youtube is not the source of scientific studies into processor performance you think it is, there are videos that show the Exynos is faster which invalidates the basis of your claim.

What I would prefer to rant about is that you cannot get a dual SIM S21 series in the US unless you import one from Europe etc (Exynos) or from Taiwan/Hong Kong (Snapdragon). I had to buy my Ultra from Amazon Germany and I love it so far. It also has a working eSIM which I have already used when travelling to avoid having to get a local SIM. That also meant I lost out on all the Samsung discounts on part exchange in the US.
And, of course, there is no international warranty with my phone.
