Samsung Galaxy S21: Your complete buyer’s guide to the new S21 series

by Joseph K. Clark

Some things in the mobile tech space are constant every year, one is that we get a new Samsung Galaxy S to release early. That was no different for 2021, but Samsung gave us the Samsung Galaxy S21 back last January rather than making us wait until March or April. This year’s flagship series brings a mix of expected and drastic changes compared to the previous year’s S20 family, including spec upgrades, a refreshed design, and all-new camera tech. Whether you’re in the market for a price-conscious flagship or something that goes all-out, the S21 series has something for you, and we’re here to help you find out everything you need to know before you buy one for yourself — or buy them for the whole family.

Killer flagship

Samsung Galaxy S21

For many shoppers, the baseline Galaxy S21 will be the go-to choice over the flashier S21+ and S Pen-compatible Ultra. It has a compact and user-friendly size, incredible performance with the Snapdragon 888, capable cameras, and a large battery. You get all this for just $800, making it a great deal.

Samsung Galaxy S21 Price

Samsung cut prices across the board this year with the Galaxy S21 series, meaning you’ll get more bang for your buck while still getting an utterly premium experience. All three models start with 128GB of storage, but you can pay an extra $150 to double your storage to 256GB or quadruple the Ultra’s storage to 512 GB. That option is extra crucial given the S21 doesn’t have a MicroSD slot to add on hold later.

Phone128GB Storage256GB Storage512GB Storage
Samsung Galaxy S21$799.99$849.99
Samsung Galaxy S21+$999.99$1049.99
Samsung Galaxy S21 Ultra$1199.99$1249.99$1379.99

A starting price of $800 for a Samsung flagship is something we haven’t seen in a couple of years, and the amount of power and performance you get for that price is quite impressive. This move would be praised any year, but it’s especially welcome after 2020’s economic instabilities and people still dealing with tighter budgets than usual.

Samsung Galaxy S21 Availability and Deals

If you’re ready to buy a Galaxy S21 for yourself, the good news is that you can go out and buy all three models worldwide right now! Furthermore, you owe it to yourself to check out some of the best Galaxy S21 deals.

Samsung Galaxy S21

If you buy directly from Samsung’s website, trading in an eligible phone will get you up to $700 for an instant discount on your purchase. You can get up to $100 in instant credits for another Samsung purchase, a free Galaxy SmartTag, and four free months of YouTube Premium.

T-Mobile has one of the most appealing carrier deals, offering up to $800 in credits when trading in an eligible phone — effectively making the regular S21 accessible. This is a standout offer because older and cheaper phones like the Galaxy S9 and Pixel 4a will still get you that $800 credit.

Samsung Galaxy S21 Which should you buy?

We’ve already mentioned three distinct versions of the Galaxy S21 to choose from, but looking at the big picture for these phones, how do they compare to one another? Let’s break that all down real quick.

The regular Galaxy S21 is the phone to buy if you want the core S21 experience while spending as little as possible. It has the same Snapdragon 888 processor found in the other two models, there’s an AMOLED display with a 120Hz refresh rate, and the updated camera setup ensures you can capture whatever life throws your way. There is a plastic design compared to the glass build of the S21+ and S21 Ultra. However, you won’t get UWB connectivity in those more expensive handsets. If none of that bothers you, the S21 is a great deal at just $800. If you want a closer look at everything it offers, check out our Galaxy S21 review.

Then we have the middle child, the Galaxy S21+. It has a larger display and a bigger battery than the baseline S21, which are two notable perks if you plan to watch many movies or play many games. The design is also a bit nicer thanks to the glass back, and if you care at all about UWB, that is present here. The camera system and processor are identical, so unless you need a larger display and battery, you could buy the S21 for a similar experience and save some serious cash. And, of course, there’s the Galaxy S21 Ultra. This is the phone you buy if you want the very best that Samsung had to offer in 2021, and in doing so, you’re treated to one heck of a phone.

The heart of the S21 Ultra is the same Snapdragon 888 chipset, but it brings meaningful upgrades to the table in almost every other regard. For starters, the display resolution is upped from Full HD+ to Quad HD+, adding more significant variability to the refresh rate (allowing it to scale from just 11Hz to 120Hz). The cameras are also entirely different — the primary camera is a 108MP sensor, and you get two telephoto ones for incredible zoom shots. More minor changes include more RAM, Wi-Fi 6E instead of Wi-Fi 6, and a massive 5,000 mAh battery. Oh, and it’s compatible with the S Pen!

Given all of the upgrades the S21 Ultra brings, you might be wondering what the point of the Galaxy S21+ is. Our Galaxy S21 Ultra vs. Galaxy S21+ comparison clarifies which phone is on top. Between the higher-resolution display, vastly improved cameras, and S Pen support, the Ultra does a lot to justify its $200 premium over the S21+. It’s not a perfect phone, but if you read through our full Galaxy S21 Ultra review, it becomes easy to see why it stands out as one of the best of the year.

Again, the lack of expandable storage on the Galaxy S21 series is seen as a bummer to many, but honestly? MicroSD cards were slower than the internal storage, so I don’t envy Samsung for eliminating a bad experience. For most folks, 128GB will be fine, but if you need help deciding on a storage option, we can help you determine which Galaxy S21 storage size to buy.

Samsung Galaxy S21 Design

As you’ve probably noticed, the Galaxy S21 looks quite different from previous releases. We still have large, bezel-less displays with a centered hole-punch cutout, but looking at the back, we’re treated to a new design we haven’t seen before.

The camera housing is now integrated with the phone’s frame, seamlessly flowing into it. It’s a pretty drastic change that you’ll either love or hate and if you ask Samsung, it’s “the biggest step forward in design for the Galaxy S series ever.”

It doesn’t make much of an impact in day-to-day use, but this allows for some pretty unique color combinations — specifically, giving the camera housing a different accent color than the rest of the phone.

Samsung has always had fun with its color choices, and for the Galaxy S21 series, that looks to be the case more than ever. If you are unsure what color Galaxy S21 you should buy, I’d recommend going with Phantom Violet (it looks so freaking good!).

Samsung Galaxy S21 S Pen

The first Galaxy Note was an essential device for a couple of reasons. Not only did it usher in a new era of large smartphones for the entire industry, but it also introduced us to the S Pen. The S Pen has been a staple of every Galaxy Note since then, and up until now, it’s been a feature kept exclusive to the Note series.

Samsung’s shaking things up with the Galaxy S21 Ultra, allowing the phone to work with past S Pens and selling a new one alongside it as a $40 accessory. You can use it to draw, take notes, annotate documents, and anything else you’d typically use the S Pen for.

Samsung’s big move is to allow S Pen support on a Galaxy S device. Paired with rumors that the Galaxy Note family could be done for this year, it’s likely just the beginning of even more devices working with the S Pen later in 2021 and beyond.

The Galaxy S21 Ultra doesn’t have a dedicated slot for the S Pen, so if you’re going to use one full-time with your Ultra, we have some S Pen tips and tricks you’ll want to read up on, especially that first tip about ditching the Samsung S Pen cases and getting the Spigen Liquid Air P (Pen Edition) instead. It’s less bulky, won’t show every spec of grease, grime, and lint in your pocket, and is much more affordable.

Samsung Galaxy S21 Comparisons

The Galaxy S21 lineup is damn impressive in a bubble, but as you start stacking them up side-by-side, how do they hold up? Here’s what we’ve learned from our comparisons so far.

In the case of the Galaxy S21 Ultra vs. Galaxy S20 Ultra, the winner is clear as day. Last year’s S20 Ultra still has a lot to offer here in 2021, but between the improved cameras, more powerful display, and more excellent design, the S21 Ultra is the better overall smartphone. The S20 Ultra is more expensive than the S21 Ultra despite being a year older. If you’re debating upgrading from a Galaxy S21 vs. Galaxy S20, it’s almost a no-brainer as long as Samsung’s trade-in incentives continue: I traded in my S20 to get an S21 for $200 and have no regrets three months later. However, the Galaxy S21+ vs. Galaxy S20 Plus doesn’t come off as rosy for the S21+; if you have last year’s model, you can be content sticking it out another year and seeing what the S22 has in store.

While Samsung’s camera prowess is evident, one phone series still beats it when you compare the Galaxy S21 vs. Google Pixel 5. That prowess enough isn’t enough to justify the weaker processor and screen at almost the same price, but if the camera is your most important feature, it’s worth keeping in mind. If the part you’re most obsessed with is S Pen Support, the Galaxy S21 Ultra vs. Galaxy Note 20 Ultra asks which you prioritize more: the S21 Ultra’s quad-came setup and latest software or a dedicated silo for the S Pen. The Galaxy S21 vs. Samsung Galaxy S20 FE also pits value flagships against each other, but the S21 takes the edge with newer processors and many more great trade-in deals.

Another fun pairing comes with the Galaxy S21 Ultra vs. iPhone 12 Pro Max. These are the two best phones offered by Samsung and Apple, respectively, and that means you can’t go wrong no matter which one you purchase. The S21 Ultra is an outstanding choice for folks that prefer Android, the iPhone 12 Pro Max is the best phone to buy if you’d instead use iOS, and that’s basically what the comparison boils down to. Similarly, the Galaxy S21+ vs. iPhone 12 Pro mostly boils down to which OS you prefer, but the S21+ gets the edge for feeling better in hand and having a 120Hz screen as opposed to the 12 Pro’s 60Hz, and this goes double when pitting the Galaxy S21 vs. iPhone 12.

Samsung Galaxy S21 Accessories

We’ve said it a few times before, and I’ll repeat it: a good phone isn’t complete without the proper accessories. Especially in the case of the Galaxy S21 lineup, where you’re making a hefty investment in your new phone, it’s in your best interest to keep it protected as best as you can.

The regular S21’s backplate may be made of well-finished and durable plastic, but ignoring the best Galaxy S21 cases is not an excuse. From adding more grip to giving the phone a bit of style, it’s an essential accessory you can’t ignore. Thanks to the glass backs of the other two models, shopping for the best Galaxy S21+ cases and best Galaxy S21 Ultra cases shouldn’t be something we have to tell you to do twice.

Of course, nothing will transform your new phone into a paperweight faster than a shattered screen, so check out the best Galaxy S21 screen protectors to ensure that the lovely 120Hz screen stays intact. The Best Galaxy S21+ screen protectors will keep that 6.7-inch screen safe and unharmed while still letting you use the in-screen fingerprint sensor, and the Best Galaxy S21 Ultra screen protectors will protect your curved screen while not interfering with your S Pen.

No matter which variant of the S21 you get, it’s also worth diving into the best Galaxy S21 accessories overall. From portable battery packs, car mounts, smartwatches, USB-C audio adapters, and more, there’s much out there to further elevate your experience with Samsung’s latest and greatest.

There are many options, all delivering the maximum 25W charge speeds the S21 can. There’s also a variety of best wireless chargers to let you top off without having to plug in every single time! And, since the Galaxy S21 doesn’t come with a charger in the box, you’ll also want to check out the best Galaxy S21 chargers.

If you’re still missing your microSD card slot on the S21, we’ve rounded up the best microSD Alternatives between wireless storage, USB-C thumb drives, and good old-fashioned SSDs to help ensure your storage needs are met.
