Editors’ Note: After two months of testing the Galaxy S21 Ultra alongside other flagship phones, we have revisited this review to raise its rating from 4 to 4.5 stars and bestow our Editors’ Choice award. In addition, US wireless carriers have revealed C-band 5G plansC-band 5G plans that the S21 Ultra is well positioned to take advantage of, and the phone is now widely available for less than its high list price.
It’s like an anime title: “Galaxy S: Redemption.” The Samsung Galaxy S21 Ultra is, by and large, what the Galaxy S20 Ultra should have been. It’s a solid and premium-feeling phone with a unique (for the US) superzoom camera, a gorgeous screen, and future-forward network chops. The S21 Ultra sets the bar for Android performance in 2022 and its superzoom camera will lead you to look the world in new ways.
Now that we’ve closely compared it with the Apple iPhone 12 Pro Max and the OnePlus 9 Pro as well as Samsung’s own Note 20 Ultra, we can say with confidence that the S21 Ultra is our Editors’ Choice.
The Top of the Galaxy S Line
Samsung has three models in its 2022 flagship Galaxy S series: the small S21, the medium S21 Plus, and the large S21 Ultra. They all have the same basic processor and modem. The S21 and S21 Plus are similar, other than their screen and battery sizes. The S21 Ultra pours on features the other two lack: a 108-megapixel main camera, a 40-megapixel selfie camera, a 10x optical zoom camera, S Pen tư vấn, Wi-Fi 6E, and UWB directional positioning.
Big, medium, or small: Choose your Galaxy S21.
Pricing on these phones has been a little odd, and the original pricing led us to downgrade themperhaps more than we should have. The list prices are $799.99 for the S21, $999.99 for the S21+, and $1,199.99 for the S21 Ultra. But they’ve cost considerably less pretty much everywhere since launch. The S21 Ultra is $999.99 both Amazon and Best Buy this writing, and Samsung has an intense trade-in trò chơi. That makes the S21 Ultra effectively less expensive than the iPhone 12 Pro Max ($1,099), which is rarely discounted.
A Sleek Design With Integrated Cameras
The S21 Ultra starts with a body toàn thân that feels less cobbled-together than the S20 Ultra did. My review unit is a solid matte block that resists fingerprints much better than last year’s glossy models. At 6.50 by 2.98 by 0.35 inches (HWD), the S21 Ultra is slightly shorter than the S20 Ultra (6.57 by 2.99 by 0.35 inches), but taller and narrower than the iPhone 12 Pro Max (6.33 by 3.07 by 0.29 inches). The phone is brick-heavy, though, 8.08 ouncesheavier than the Galaxy S20 Ultra (7.76 ounces), the iPhone 12 Pro Max (8.03 ounces), or the Samsung Note 20 Ultra (7.34 ounces).
The S21 Ultra’s matte back is less slippery and more attractive than the S20’s glossy back.
The biggest and best design difference from the S20 is the better-integrated camera module. Rather than a discrete, hard-edged bump on the back, it’s now merged into the corner of the phone. There’s still a lip where it drops off, but it’s a lot less annoying and less likely to catch on your pants pocket.
The phone is rated IP68 for water resistance and comes in a range of very low-key colors (some only available if you buy the phone directly from Samsung): black, brown, gray, navy, and silver. If you’re looking for poppy-red, rose gold, or violet, you’re going to have to go with one of the smaller units.
The S21 Ultra models come in very businesslike colors.
You can opt for 128GB or 256GB of storage with 12GB of RAM, or 512GB of storage with 16GB of RAM. There is no microSD card slot. Slots and ports in general are, alas, going the way of the dodo; not enough people use them, and built-in memory has faster performance. If you absolutely need expandable memory, stick with the Note 20 or the Note 20 Ultra.
The new, second-generation Qualcomm ultrasonic fingerprint sensor is noticeably faster and more accurate than the sensor on the S10 and S20. On the other hand, face recognition repeatedly failed to recognize my face (with or without a mask).
The 6.8-inch, 3,200-by-1,440-px screen is covered in the new Gorilla Glass Victus. It hasn’t scratched after a few days of testing, an improvement over the Galaxy S20+ screen, which scuffed up quickly.
Samsung says that the screen is 25% brighter than the Galaxy S20 Ultra, 1,500 nits maximum brightness. More importantly, it has a 50% better contrast ratio, and I can see the difference. Samsung’s screens have always popped, but this one really stands out. You can set the screen resolution to 1080p or quad HD to save battery and increase trò chơi frame rates, but the option to manually switch between 60Hz and 120Hz refresh rates is now gone; instead, the display automatically changes from 10Hz up to 120Hz depending on what you’re looking .
The S21 has a truly gorgeous display.
The Ultra is the only thành viên of the S21 family that works with Samsung’s S Pen, the active, pressure-sensitive stylus previously reserved for the Note series. I tried it with a Note 20 pen, a Note 9 pen, and a Note 4 pen; all of them worked. If you don’t have an old Note, you can buy an S Pen for $40, or a bundle of pen and pen-holding phone case for $70.
The S21 has the same super-low 9ms latency as the Galaxy Note 20 Ultra, updating the screen with its virtual ink 120Hz. The button on the pen, which “clicks” on the screen, works, but Bluetooth functions such as making air commands and using the pen as a remote camera shutter don’t. Samsung says there will be a special S Pen available later this year that will have those features.
We’ve heard rumors that there may be no Galaxy Note phone this year because of a global processor shortage. If that’s the case, it makes the Galaxy S21 Ultra, with its pen-holding case, the go-to phone for previous Note owners and anyone who wants to scribble.
You can use any Note pen to write on the S21 Ultra’s screen.
Choosing the Right Model
As always, there are a bunch of different sub-models of the Galaxy S21, noted by a letter the end of the product number. We tested the unlocked U model, destined for the US. The U model has a single SIM slot, a Qualcomm Snapdragon processor, disabled e-SIM functionality, and all the appropriate bands for all US 5G networks, including millimeter wave and the upcoming C-band. Here are the other models listed on Samsung’s site:
W: For Canada. Snapdragon processor, single SIM plus eSIM. Similar 5G to the US except no mmWave.
B: Exynos processor, single SIM plus eSIM. Has 5G bands 3/7/28/41/78, so it won’t work on any low-band US 5G network.
N: For Korea. Exynos processor, single SIM plus eSIM. Only 5G band is 78.
0: For China. Snapdragon processor, dual SIM.
If you use your phone outside of its intended region, you can expect it to have all of the right 4G bands but miss some of the roaming region’s 5G bands, and you probably won’t be able to use Wi-Fi calling or similar features.
CPU: Lucky Number 888
The Galaxy S21 models are the first phones to use Qualcomm’s new Snapdragon 888 processor. The chip enables new features without really enhancing benchmarked speed. However, in the long run, the features probably matter more.
The S21 Ultra scored 1,128 on Geekbench single-core and 3,500 on Geekbench multi-core, a rise of 15% SC and only 7% MC over last year’s Galaxy Note 20 Ultra. On the GFXBench Car Chase benchmark, offscreen frames went from 57fps to 65fps, a rise of 14%. Is it an improvement? Sure. Will you notice it? Maybe not.
The iPhone 12 Pro’s Apple A14 processor scores noticeably higher on both benchmarks: 1,599 SC/4,006 MC on Geekbench, and 70fps on the offscreen GFXBench Car Chase benchmark.
Similarly, while the Basemark Web web-browsing score jumped from 322 on the Note 20 Ultra in WQHD+ resolution to 498 on the S21 Ultra, and from 486 in 1080p resolution to 605, the iPhone 12 Pro already scores 600.
See How We Test PhonesSee How We Test Phones
There’s some weird stuff going on that makes me question the value of these numbers. The PCMark and AIMark benchmarks appear to be broken on the S21 Ultra, delivering scores that are obviously far too low. That could be something about the 888 itself or about Android 11, but in any case, they don’t appear to give good guidance. The S21 Ultra far outperformed the S20 Ultra on AI Benchmark, but once again, I’m not sure whether or not to trust it. We’re working with Samsung to figure this out and will update this review once we know more.
What you’re more likely to care about is that the 888 lets the S21 Ultra do some impressive new tricks. For instance, the 888’s image signal processor lets the S21 Ultra combine its two telephoto cameras for much better 10x30x zoom than last year, and a new Director’s Mode video feature lets you smoothly switch between cameras on the fly. The AI capabilities lead to a better Night mode. Wi-Fi 6E requires a component in the 888, as do some of the new 5G features. So even without reliable benchmark numbers to quantify speed and power, it’s clear that this is a big step up from last year’s models.
A Streamlined Android Experience
The Galaxy S21 Ultra runs Android 11 with Samsung’s OneUI 3.0 extensions. Samsung told me it’s committing to updating the phone as far as Android 14.
The bloatware situation on the unlocked units isn’t bad all, but you should expect the usual dozens of unwanted apps on carrier-locked models, especially on AT&T. Samsung does preload fb, but it’s deletable.
Samsung’s voice assistant, Bixby, is still on this phone, but the Bixby trang chủ screen to the left of the main home screen is gone; instead, you now see Google’s news feed. If you want to disable the Bixby button presses and turn the power key into a real power key, you can do that in settings.
Samsung gets rid of its unloved Bixby trang chủ screen and puts Google’s browser front and center.
It’s worth pointing out that Samsung does its best to link to other Galaxy devices and Windows laptops, similar to how iPhones hook up to Macs. OneUI 3 lets you call and text from Galaxy tablets or speakers. On Windows laptops, you can answer texts, check notifications, or mirror your phone screen. You can also put the S21 in multi-windowed Dex mode for presentations on a big screen or use an additional keyboard and mouse.
Samsung’s home screen design still won’t be mistaken for Google’s, with its own colors, icons, and dialer. But OneUI 3.0 works hard to integrate all of Android 11’s features while keeping Samsung’s identity strong, and it doesn’t push custom browsers or email apps on you when it knows Google’s apps are what you really want. Besides, Samsung’s overall market success speaks to how accessible users find its UI.
Beefy Battery
The S21 Ultra has a 5,000mAh battery. In our standard test, where we run a YouTube video with full screen brightness over Wi-Fi, we managed 11 hours and 20 minutes; that’s on par with other leading large phones. Changing the screen resolution and refresh rate doesn’t matter here, because the refresh rate adapts to the content: If you’re showing a 60fps video, the refresh rate will not be higher than 60fps, even if you have it set to 120fps. The Ultra showed about an hour more playback time than the smaller S21.
5G does hit the battery pretty hard. On AT&T’s network, streaming over 5G rather than Wi-Fi incurred a three-hour battery penalty in testing. You can’t turn off 5G natively on AT&T or Verizon, though you can on T-Mobile. There’s a third-party app called Samsung Band Selector that might let you force your phone to use 4G, but it’s unsupported and could be disabled any time.
The S21 phones tư vấn both 25W wired and 15W wireless charging. Samsung no longer ships a charger with them, claiming it’s because most people already have USB chargers they can use. However, most of the USB chargers you’ve accumulated over the past several years have USB-A ports and Micro USB cables, which are useless for the USB-C-to-USB-C cable that’s included in the S21 box. Even if you do have a USB-C charger handy, its vintage and power will make a difference. Plugged into a 22W Galaxy Note 20 Ultra charger, the S21 Ultra got to 37% in 20 minutes and reached a full charge in 70 minutes. But plugged into a Galaxy S20 FE charger, it only reached 22% 20 minutes, and it took a total of 110 minutes to fully charge the phone. You can always opt to avoid the cable question altogether and get a Qi-compatible wireless charging pad.
Networking That’s Ready for 2022
The Galaxy S21 series is ready for the networks of 2022, and they’ll arrive before you know it.
The S21 phones are the first US models with Qualcomm’s new X60 modem. The X60 lets phones combine non-contiguous channels of 5G, which earlier devices couldn’t do. In theory, that improves 5G performance. In practice, the networks aren’t quite ready for it yet.
There’s also tư vấn for C-band, the fast new frequencies that carriers just spent more than $80 billion for. Verizon says it’ll cover 100 million people with C-band access by next March, which will likely triple the carrier’s 5G speeds. Given the poor performance of Verizon “nationwide” 5G right now, I think anyone investing in a flagship phone for the next few years on Verizon needs to make sure they have C-band.
I tested the S21 on AT&T and T-Mobile. (Our Verizon SIMs are fried right now.) 4G and 5G performance on AT&T was very similar to last year’s flagship devices. AT&T will, in the future, use the X60 to enhance nationwide 5G performance by adding new channels of 5G. In the meantime, there’s not much new to see here. Over 11 locations, the S21 Ultra averaged 113Mbps down and 20Mbps up on AT&T’s “nationwide 5G” network, while an iPhone 12 got 111Mbps down and 20Mbps up.
On T-Mobile, things got interesting. T-Mobile’s network forced my S21 into “standalone 5G” mode. Most 5G connections in the US right now are least half 4G. Standalone 5G, which eschews 4G, gives you lower latency and less chance of overloaded networks in crowded conditions, but you end up with slower overall speeds because you’re losing the add-on 4G components.
With standalone 5G, I got an average of 87Mbps down and 31Mbps up with 12ms latency, which was much slower than my Galaxy S20+ and iPhone 12. By forcing the phone into non-standalone mode using a field test screen, speeds rose to 258Mbps down and 69Mbps up on average, with 26ms latency. That was very similar to both the S20+ and the iPhone 12. T-Mobile told me, essentially, that its engineers were experimenting in my neighborhood and would fix it.
On T-Mobile, the S21 should be able to combine the carrier’s two current main forms of 5Gbands n41 and n71in a way that no phone so far has been able to do, but I didn’t see that happening; the phone was always on n41 or n71. That isn’t down to the phone, though. The network just wasn’t ready.
On the Wi-Fi side, the S21 Ultra is the first phone with Wi-Fi 6E, the new form of Wi-Fi that enables extremely high speeds on the new 6GHz band (which isn’t the same as 6G). I couldn’t test it; the first Wi-Fi 6E routers are just coming out now, and they’re $500 or more. Wi-Fi 6E looks like a much bigger jump in terms of performance than Wi-Fi 5 to Wi-Fi 6 was; my Wi-Fi 6 devices still tend to max out around 600Mbps in real-world speeds, but Wi-Fi 6E promises more than a gigabit per device. This will become especially relevant when you’re hooking your phone up to multi-gigabit home internet service, when and if that appears in the next few years. It also helps with hotspot mode when you’re connected to millimeter-wave 5G, as those connections can already go over 2Gbps.
With UWB, smart tags can tell you not only whether you’re near them, but which direction they’re in.
The Ultra also supports UWB, a new wireless technology that I can’t find a use for yet. UWB adds a directional element to short-range wireless, so you can eventually get, say, a virtual car key app that opens your car door when you’re pointing the car, or a Smart Tag that tells you not only whether you’re near it, but which direction it’s in. For now, its only use is in a “nearby share” function that shares files between two phones, and honestly, that works just fine using Bluetooth or Wi-Fi.
Bluetooth 5.2 lets the phone stream to two devices simultaneously; how this works in practice will depend on the Bluetooth devices in question. With the Galaxy Buds Pro earphones, it means the phone streams to each earbud independently rather than going to one main earbud, which relays to the other. That makes for more stable connections.
Meanwhile, we lose one key wireless technology: MST. Samsung’s phones used to work with older credit card swipe machines that didn’t have the Apple/Samsung Pay specs. That was something Samsung had over Apple. The S21s don’t have that.
With all this talk of data, we didn’t forget about using your phone to, you know, make phone calls. Call quality hasn’t been a concern on high-end Samsung phones for a few years now. The company has speaker and Bluetooth call quality nailed. If you want to use a wired headset, it has to be USB-C; there’s no headphone jack. I was very happy to see that Wi-Fi calling was finally available on my unlocked model on all three major US wireless carriers. Samsung repeatedly promised AT&T Wi-Fi calling on the unlocked S20 but never delivered.
The unlocked US model we tested has a single SIM slot. The phone technically supports eSIM, but it’s been disabled on this model, and Samsung has shown no sign of intending to enable it. Treat this as a single-physical-SIM phone.
The Camera on the Phone Goes Zoom Zoom Zoom
The Galaxy S21 Ultra’s cameras are what the S20 Ultra’s were supposed to be. It has a 108MP main sensor that generally takes 12MP photos, along with a 12MP, 120-degree ultrawide camera, two 10MP telephotos (3x and 10x), and a dedicated focus sensor. That focus sensor is key. The 108MP main sensor uses phase detection rather than dual-px autofocus, and on the S20 Ultra, that meant slow and often inaccurate autofocus. We don’t have that problem any longer. At 1x, images have better contrast than the photos taken by the S20 Ultra, and are much sharper the edges of the frame.
In my close-up shot test, I found the S21 Ultra fixed another one of the S20 Ultra’s flaws: a really painfully narrow focus plane that meant most objects in the shot would be out of focus. The S21 did much better keeping different elements of a setup in focus, though its photos weren’t quite as sharp as those from the iPhone 12.
Left: iPhone 12. Right: S21 Ultra.
Photos taken in the S21’s Night mode are leaps and bounds ahead of the dimmer, muddier shots from the S20 series, but the iPhone 12 is still the king of the night. Its Night mode turns night to day with a sharpness the S21 can’t quite match.
Left: iPhone 12. Right: S21 Ultra.
What you don’t see in the images here is that the camera is noticeably faster and easier to use than the S20 series cameras are. It takes the same night shots, but with about a second less waiting. High-level zoom, which is really shaky on the S20 series, is now stabilized so it’s much easier to lock onto the part of the image you need.
The S21 has a 40-megapixel front-facing camera that normally shoots 10MP images. The big difference between this and the S20 generation is Night mode; the S21 has one, so you can finally take decent selfies in the dark. Are they soft? Yes. But the fact that they come out all is a positive.
Left: S21 Ultra. Right: S20 Ultra.
With good light, that front-facing camera is actually great, with more detail than the S20 Ultra, and better contrast than the iPhone 12.
Left: iPhone 12. Right: S21 Ultra.
The S21 Ultra’s zoom cameras are a big part of what makes it worth its price. The phone has 3x and 10x zoom cameras for, Samsung claims, up to 100x zoom. Things look good up to 10x. It’s safe to say that if you want to live 10x, this is the phone for you. Beyond 10x, it’s all digital zoom on the 10x zoom lens. But since it’s digital zooming from a native 10x, the images don’t look so bad up to about 30x.
The S21 Ultra shines in daylight 10x and 30x zoom. Shots 10x are actually distinct, and while the 30x shots are definitely soft and digitally zoomed, they aren’t the mushy haze you get with the S20 series or the small S21.
The Galaxy S21 Ultra 1x, 10x, 30x, and 100x zoom.
At 100x zoom, things are definitely impressionistic. But the 100x zoom isn’t useless the way the S20 Ultra’s was. The viewfinder stabilizes so it isn’t wobbling all over the place, and handheld shots are better. Not great, but better.
Top: S21 Ultra 30x and 100x. Bottom: S20 Ultra 30x and 100x.
It’s worth noting that the S21 Ultra can do 4K60 video recording up to 10x zoom, and can do 8K video 24fps using its main lens. While recording 8K video, you can pull out 33MP snapshots.
Is the Price Justifiable?
The Galaxy S21 Ultra is an impressive, high-quality superzoom camera phone. When we first reviewed it in January, we were a little hesitant. It was big and heavy, the list price was high, and carriers hadn’t released their C-band plans.
I’ve now been using the phone as my primary device for a while, and things have changed. For one thing, the list price is a lie; nobody seems to be paying it. For another, Verizon is going whole hog on C-band in less than 12 months. And the more uses I find for the 10x zoom and games I play on the big, bright screen, the more I appreciate just how well this phone is put together.
Samsung has some accessories to sell you, too: a watch, earbuds, and a smart tag locator.
The S21 Ultra’s top competitors, as big phones, are Samsung’s $1,299.99 Note 20 Ultra, Apple’s $1,099.99 iPhone 12 Pro Max, and the $969.99 OnePlus 9 Pro. The Note 20 comes with an S Pen and a microSD memory card slot, but the S21 Ultra is more future-facing as a long-term investment. The iPhone has nothing like the S21 Ultra’s superzoom, but it has somewhat better night performance and, for serious photographers, a much better ecosystem of third-party camera apps and integration with Mac computers. The OnePlus 9 Pro has speedy, elegant software and is also a great choice, but the S21 noses just ahead of it on radio performance and superzoom. The verdict is in: The Samsung Galaxy S21 Ultra is our Editors’ Choice for flagship smartphones.
