[@katinasoutherland7693]

The s21U is one of the BEST-looking phones Samsung or anyone has ever made. I still can't believe they didn't give us 2 generations of that look. I wasn't gonna upgrade my s22U. it's just im getting tired of the stuttering & lag at times. This started happening after the last update, 🤷‍♀️ i was gonna stck it out, but im thinking what the HELL.

[@altair7744]

It's quite funny to see the S21 Ultra compared to the S25 Ultra, the screen of the S21 Ultra looks more protruding upwards than the S25 Ultra, previously I thought the S25 Ultra's screen looked longer and I don't like smartphones that have screens that are too long like the Z Flip. and anyway, your channel is great, it's quite rare on other channels they always forget to compare the sound of the speakers, I think this is an important thing and thank you for answering it👌

[@marvinkalela3528]

Honestly the s21 ultra design is Awesome Only let down by shit processors SD888 🔥🔥 EXY 2100 thermal issues

[@laq5796]

samsung design peaked with the s21

[@Smzxe]

Note 7 S7 edge were best looking phones ever S10 looked slightly better than s21

[@chrislee3414]

I have the S21 ultra, and I'm looking to upgrade, but the ONLY reason I want to upgrade is for more storage. I have the 128G version, and it's about as full as it can get and has been for a long time. I dont care about AI, which seems to be the main new feature that they're pushing, and the S21 Ultra performs more than well enough for my needs. If this phone had an SD card slot, I'd be happy with it for another 3 or 4 years. It's hard to justify the cost when all I really need is the equivalent to a $35 SD card.

[@georgiasking7916]

Same bro, I thought waiting 4 years I would be able to have a real upgrade by now. I'm excited to have more storage and better battery life.

[@radiantbladez]

I just updated mainly for storage and battery life. I've had a 500 gb S21 Ultra since launch and I'm always having to delete stuff. I do a lot of content creation so it's really annoying. If I had an SD card option, I would have definitely stayed on my 21. However, the S25 Ultra is a lovely phone. Still transferring all my stuff to it, but hopefully I can get this 1tb to last 4-5 years 😅

[@-DC-]

Updated phones are mainly marketing at this point, If your current phone is doing all you need don't spend your money it's insane.

[@KevoIogy]

S21 Ultra has a better design in my opinion. the camera portion looks nicer, and the screen is curved making it look more premium

[@devilkazumi578]

But the chip sucks

[@KevoIogy]

@devilkazumi578 still a great phone if you can cope with the heating (I had an S21 Ultra a few years ago, the heating wasn't that bad with power saving mode)

[@Ayansh0.]

Can you do a comparison video of the Galaxy S25 ultra and the Galaxy S23 ultra? ❤❤❤

[@matthews-tech]

Yes will drop tonight actually

[@jamesgana3837]

Funny enough, the S21 ultra in en vogue now because the S25 ultra is now a curve display and edges

[@slytheravenx2716]

Nope, S25 has no curved display, only rounded corners.

[@mansourzare6144]

My phone is same as s21U and s25U (A52s) 😂😂

[@ajaj3025]

You're very, very correct. All those a series are very good and perform as the ulras.

[@brandonlee7382]

S21 ultra was a great design. S25 ultra looks too safe. It's like they are trying to be like iPhone. Why would I want samsung to be like iPhone? I would just buy iPhone in that case. I know samsung has copied iPhone in the past but they always done it better instead of a direct copy. Samsung does have all the AI stuff which blows away iPhone AI.

[@MrJeet-p9i]

This is the video I have been anxiously awaiting for ! I am thinking about purchasing a Samsung Galaxy s21 ultra to add to my collection.

[@meetdtruth5600]

This is actually a video I was waiting for... Nice job mate your showed them!

[@Sathure]

Was in the same boat. The 500$ offer for a 4 year old phone and the 7 years of updates got me to upgrade, being that 15 is the last major update for the 21. Difference isn't massive but with the 7 year update schedule just means i'll likely hang on to this one even longer. Smart phones have peaked at this point, upgrading every 1-2 years is pointless now.

[@jacobcrelia1778]

Exact same boat.

[@shaphetsunday]

Got the s25 ultra cause I had to, but I did not have the heart to trade in my s21 ultra, still love the phone like day 1

[@techultron_etron]

@@matthews-tech Nice man 👍🙂

[@unorevers7160]

When you open geometry dash and says "Its not a huge difference" that is a bit misleading. In fact there is barely any difference. I slowed the video to 0,25x speed and the s21 actually comes out on top. At this point CPU upgrades are useless, unless they improve efficency for longer battery life. I really appreciate the video (left a like). But you could improve the way you descibe the differences. In the video it is a bit to suggestive. E.g when you open Pubg you say the s21 Ultra still qualifies for casual gaming, implying that the s21 Ultra can not play high fidelity mobile games. Which is just untrue. In fact I argue that you will barely see any difference even in the most demanding mobile titles.

[@Jayyy.473]

I got the s21 ultra but to be very honest I want the s25 ultra because of the 7 years of OS updates and one ui 7 is our last on the s21 ultra

[@manwithoutshadow]

Yes, great point and the $500 trade in value is the sweet spot that got me to upgrade. I'm not an every year type of buyer, so this is a good time to upgrade.

[@Unknown-g5d2m]

But s24 ultra is better deal

[@xPandamon]

@@Unknown-g5d2m It depends. If you got some money to spare the S25 Ultra is the most refined package overall

[@aryan47kumar5]

Most practical comparison, I have seen so far. ❤❤❤

[@mariorossi303]

Still using my s20 ultra. It is a great phone.

[@LawpickingLocksmith]

Huge thanks! A year ago I mothballed my S21u for an Iphone 15pp. Sure making better pictures now but hey learning a new system? My S21u was used for its first year as a 5G modem and hotspot so the battery is no longer perfect. Found the editing on the Samsung is even better!

[@serrael-182]

S21 ultra had the best ultra design. Im about to sent my s25 ultra back cuz its too uncomfortable to hold. Hope my old phone works for another year...

[@S_5_Y]

On the contrary, because you are used to the iPhone.

[@serrael-182]

@S_5_Y i never had an iphone

[@patmason7276]

Guess I'll be keeping the S21.

[@Bundles06]

I waited for the S25 ultra cause of the flat screen and rounded edges, but the more I look at it, the more I see Temu iPhone S25 Pro. I could have it right now. But for the first time in my life, I can't think of any legitimate reason to upgrade. And when it comes to tech, Im a good little consumer. I love innovation. So I have apparently reached a limit. Samsung is getting boring.

[@bradleyswaney6100]

Yep. My old S21 ultra is still an Ultra! ❤😂 As for as basic use the 21 still has 0 lag.

[@ChrisVidal-gy1wm]

I was waiting for this comparison

Going from S20+ to s25 ultra or oneplus13 Which would be best & would it be worth it

[@Di_marswaggz]

S25U Ofc it's worth it

[@jamescash887]

Coming from a S20 of course it’s better but they did away with S-pen functions which is an absolute dealbreaker for me.

[@pham3383]

Do you use camera a lot, if dont one plus is enough for you if you just want your camera to only get things done ,one plus cheaper and have better battery life,Samsung better cam overall

If you can replace your phone every 5 to 6 years , try to make most of your phone.

I loved the s21 ultra when it launched, it was such an improvement over the 20. The lack of integrated Spen though really hurts it when compared to the newer ultras . I cant believe some of you guys are still using it now years later though wow.

Every big reviewer said the phone sucks which state clearly they never touch any phone beside their iPhone , I got this for over 4 year and it seems to be quite reliable

Appreciate this review. I normally keep a phone for 4 to 5 years unless the next one is a diffence, of night and day. So it's great when I find a reviewer that compares the new one to each of the last 4 to 5 phones, for people like me..

[@jakaplz]

S21U was a great phone, thanks to its smaller width it was easy to hold. The only problem with the phone in all that time was that exactly a few months after the warranty ended, the display went out. Has this happened to anyone else as well?

[@VitiateTheImmortal]

Still loving the s21U design! More than 22, 23 and 24 but the 25U finally caught my eye again too xD just got it in and so excited to open

[@jwbranham2009]

Great Comparison Video that goes to show how good S21 Ultra is.

My S21 Ultra with Exynos processor is just WAYYYYYYYY too slow now. Glad the Snapdragon variant still holds up.

[@annapg.4626]

I wish they would do something fun with the camera like on the S21 Ultra again.

[@masterblaster6470]

Got both models in my hands , and now I am thinking ,was it worth it? My S21U is still doing a fantastic job! I really thought that S25U will blow it out of the water , but not. Yes it is faster ,and I can feel it when opening and closing apps. Also got storage for Spen, but other then that it is now what I was expecting. As a matter of fact, I didn't even swap my sim card to new device and still using S21U as main phone. I feel like I just spent £1000 on something I don't really need. I think I could easy stick to S21U for another couple of years- love this phone.

[@grayaquatics852]

Honestly, the S21 Ultra IMO beats out ALL newer Samsung devices in terms of design. The phantom black S21U IMO is the goat of Samsung's designs. A close second would be that Aura glow Note 10+

[@EagleHD]

Watching on my S10

[@djrickyb]

Still using my Old work horse S10+!!! Only issue is that I finally cracked the screen, and it still works okay, but giving me a green flicker quite often so after 4 years with this phone considering an upgrade! I never buy the newest model so I know I won't get the new S25 Ultra, but looking at a refurbished S21 Ultra. Great Price on Amazon now, so considering upgrading to it even though it is a 4 year old model now.

[@JuStE835]

I've beem waiting for this comparison, as a owner of s21u,, ready to upgrade to s25u in a few weeks. I hope its worth the wait and upgrade🙏🏻😍

[@Sebyyy_1]

What setting do you have the s21 ultra at? Because mine is lagging at 120hz for no reason. I just got it a week ago.

[@DestroyerJoni20]

i've used the S25 ultra for 2 whole days now and coming from the s21 ultra, its amazing. 4 main things I noticed tho along with all the other nice stuff: - The battery is litterly unkillable, I went from charging my phone (s21) twice a day (I used max battery protection so 80%) to having over 30% left at the end of the day (again same max battery protection). - No video will show it but my god, the display is out of this world, the S21 ultra is good but the 25 takes it to another level - The cameras are also wild, I cant explain how bad my s21 photos come out like for like. - The s25 ultra feels A LOT lighter

[@pham3383]

The s21 design accidentally made the camera way more durable

[@B0xER911]

I love my S21 Ultra, but I swear, with every software update it gets from Samsung, the battery life shortens right after it! Like they are artificially ruining it so that I upgrade to a new model. It could barely lasts trough 1 day of light to moderate use, so I will have to spend the money for the S25 ultra... Great video, I didn't expect such little difference

[@Geared84]

I am just installing a new battery on my S24 Ultra when the time comes.

[@redvines7110]

So what all we got was downgrades in the past four years

[@samdixon7050]

S21 Ultra is ICONIC and the best phone I have ever owned. Was for me the last time a WOW phone came out that blew everyone away! Even iPhone users were tempted. To this day I have never seen or used a better phone. Sure the S25 Ultra is better of course. BUT I still LOVE my S21 Ultra...

[@ironfur9150]

My daily is still the S21U and so far I have seen little to compel an upgrade. I don't like the direction they took the camera rings on the S25U and most of the Ai features I wouldn't use. Still getting all day battery on my S21U, looks like I may be holding out for at least another cycle, we'll see what the S26U offers.

Wow what a deal you guys have in the US, In europe you get $200 for the 21 ultra, and you can sell a used one for $300, so I will just sell mine, but giving $500 for such an old phone is a huge motivation to return these phones. I guess Samsung Europe does not really want our phones back....

[@TubbiToSchu]

I have the S21 U and just upgraded to the S25 U and for me there is a huge difference. The S25 feels a lot better, the screen is really nice, the speakers are on another level. The camera is better, especially at night. And the AI features are impressive. Yes the S21 was a great phone and I never had a phone that long. But the S25 U is clearly better.

I just bought a S25 Ultra because its the only company in Portugal who sell in installments for foreigners like me .I Have an S21 Ultra and like it bought in Brazil back them in 2021, but then, last year it presented a green line on the screen and Samsung didnt covered because it was bought outside of EU. they are selling s25 ultra 512 gb for 1300 eur, and they gonna pay 220 eur on the s21 ultra but IDK if they really will due to the green line. I hope so. Just ordered mine, mostly because of being able to pay in installments as also the AI features it has.

[@bradmonkiewicz8375]

I was gonna upgrade till I watched. Thanks 💪🏻

[@steveroberts6302]

The big difference is that you can buy an s25 but you can't buy a new S21 otherwise I would (currrently have the note9). I've seen these adverts for "renewed" phones but I'm guessing that just means 2nd hand and I don't want to buy a phone whereby the battery is already on the way out.

Im keeping my S23U. Only like the flat display but the s-pen is a dealbreaker. I'll wait and see if S26U is anything worth upgrading, if not S27U, S28U.

Yeah I was thinking about going to S25U from iPhone. Once I learned they nerfed the S pen functions I didn’t do it. S pen is what makes Samsung unique.

I'm looking forward to S25U anyway, S-Pen downgrade is sad, but it looks and will perform much better than Exynos S21U, that does overheat and since I'm using S-Pen on S21U as well, the rounded sides are not practical at all. But... I'm buying S25U mostly because I managed to crack the S21U screen which renders a battery swap too expensive. Otherwise, I'd stick with S21U for a couple more years. (Don't care about the cameras much, only as a backup when I can't carry the Full-frame around...)
