The best Galaxy S21 Plus case from Samsung


Size: 6.4 x 3 x 0.41 inches
Weight: 0.84 ounces
Colors: Black, Pink, Violet, Gray
Materials: Silicone

For a Galaxy S21 Plus case that doesn't hide the form of Samsung's new phone inside a bulky case, turn to an accessory that comes straight from Samsung. The Galaxy S21 Plus 5G Silicone Cover slips right over the phone for a comfortable fit that lets you get a good grip on your S21 Plus.

The soft-touch silicone case comes in four colors that match many of the available colors in the Galaxy S21 lineup. It also offers some protection from drops and scratches without the added heft you'll find in more rugged accessories. You'll still have access to the S21 Plus' charging port when the phone's tucked inside Samsung's Silicone Cover, though you may need to pop it out to get the best performance when using the reverse charging feature to power up other Qi-compatible devices.

The best dual-purpose Galaxy S21 Plus case

Spigen looks to balance protection with practicality in its Slim Armor CS case for the Galaxy S21 Plus. In addition to a dual-layer design that offers protection against drops, the Slim Armor also has a compartment for storing credit cards or cash. That way, you can leave your wallet at home, toting around just your Galaxy S21 Plus.

Don't expect a lot of added bulk with the Slim Armor case. It adds another 0.24 inches to the S21 Plus's 0.3-inch depth, so the case will be able to slip into a pocket easily. You can also charge the phone wirelessly when it's still inside the Slim Armor (though you'll want to make sure that you remove the cash and credit cards first).

3. Otterbox Symmetry Clear Series for Galaxy S21 Plus

Best protection for the Galaxy S21 Plus


Size: 6.6 x 3.3 x 0.47 inches
Weight: 0.09 ounces
Colors: Clear, Stardust, Shell Shocked
Materials: Polycarbonate, synthetic rubber

Let your Galaxy S21 Plus' inner beauty shine through with the Symmetry Clear Series from Otterbox. This case lets you show off the look of your new phone with a clear plastic design, though Stardust and Shell Shocked variations on the clear version add patterns to the case itself for a very distinctive look.

The Symmetry Clear case appeals to more than just aesthetics, though. It also offers drop protection with raised edges to safeguard the S21 Plus' cameras and display. Otterbox also touts a silver-based antimicrobial additive inserted into the case to fight microbial growth, keeping your case free of bacteria.

Otterbox's Symmetry Clear Series is made from 60% recycled plastic and it works with the S21 Plus' wireless charging feature.

4. Caseology Parallax for Galaxy S21 Plus

Best Samsung Galaxy S21 Plus case design


Size: TBD
Weight: TBD
Colors: Black, Purple, Gray, Pink
Materials: Polycarbonate, thermoplastic polyurethane

Few Galaxy S21 Plus cases look as groovy as the Caseology Parallax, a bumper case with an eye-catching hexagonal pattern on the back. That's not just to lend your phone a smart look, either — the pattern helps make the S21 Plus more grippable so that it won't squirt out of your hands at inopportune moments.

Should your phone take a tumble, though, the Parallax can help prevent damage, thanks to a dual-layer design that Caseology says has been drop-tested to ensure durability. If you don't want to take the case maker's word for it, a two-year warranty should add to your peace of mind.

5. Galaxy S21 Plus Kvadrat Cover

Most eco-friendly Galaxy S21 Plus cover


Size: 7.4 x 3.3 x 0.67 inches
Weight: 2.08 ounces
Colors: Gray, Violet
Materials: Plastic

If you try to keep your environmental footprint in mind when deciding what to buy, adding Samsung's Kvadrat Cover case for your Galaxy S21 Plus is a pretty eco-friendly choice. The case is made completely out of recycled PET bottles, and when it's time to move on to another case, Samsung's accessory is compostable.

A textured material on the surface of the case makes your Galaxy S21 Plus easier to grip, and there's a hook toward the bottom of the Kvadrat Cover for attaching a strap. That gives you multiple options for carrying around your Galaxy S21 Plus. 

Gray and violet color options complement the Galaxy S21 Plus' color scheme, and a thin profile means you can cover up your phone without making it noticeably thicker.

6. Wallet Slayer Vol. 1 for Galaxy S21 Plus

Best wallet case for the Galaxy S21 Plus


Size: 7.5 x 5.3 x 4.5 inches
Weight: 17.6 ounces
Colors: Black, Gray, White
Materials: Thermoplastic polyurethane, polycarbonate

Wallet cases let you tote around cards and cash with your smartphone, saving you valuable pocket space — especially when the case itself is already slender. The Wallet Slayer Vol. 1 from Smartish may be one of the better examples of this type of accessory for the Galaxy S21 Plus. You're able to carry around three cards along with cash, so your wallet can really stay at home when you head out.

The Wallet Slayer also boasts some design flourishes that are aimed at protecting your Galaxy S21 Plus. Air pocket corners help cushion the phone from any unintended drops while the sides of the case make it easier to keep a grip on your phone. A raised area around the S21 Plus' triple camera array keeps those lenses safe from making contact with any unforgiving surfaces.

7. Totallee Super Thin Galaxy S21 Plus case

Best thin Galaxy S21 Plus case


Size: 6.4 x 3 x 0.33-0.35 inches
Weight: 0.24 ounces (matte), 0.8 ounces (thin)
Colors: Black, Clear
Materials: Polypropylene (matte cases); TPU (clear cases)

We've profiled a lot of slender cases for the Galaxy S21 Plus, but few get as thin as the Totallee Super Thin offering for Samsung's 6.7-inch phone. The clear version of the Totallee Super Thin is just 0.03 inches thin, while the black matte version is even thinner at 0.02 inches. In other words, don't expect a lot of added material on top of your Galaxy S21 Plus.

The story doesn't stop with how thin these cases are. They're also quite durable thanks to the flexible plastic Totallee uses on both versions of its case. The clear version, in particular, stands out thanks to a TPU material that absorbs shocks.

A lip around the camera helps the Totallee Super Thin case protect the lenses on the S21 Plus from damage, and that thin design lets you wirelessly charge the phone while it's inside the case.

UAG Pathfinder Series for Galaxy S21 Plus

8. UAG Pathfinder Series for Galaxy S21 Plus

Best rugged Galaxy S21 Plus case


Size: 6.3 x 3 x 0.45 inches
Weight: 1.44 ounces
Colors: Black Camo, Forrest Camo
Materials: Armor shell

You won't confuse the UAG Pathfinder Series with any of the thin cases available for the Galaxy S21 Plus. This durable case features an armor shell that's designed to meet military drop-test standards. Urban Armor Gear carries that military theme a step further with camouflage designs for both its black and forest green options. The case maker says the Pathfinder Series gets dropped 26 times at heights of four feet with no damage done to the phone.

Despite all that protection, this isn't a very bulky case, as it weighs less than 1.5 ounces and carefully fits around the S21 Plus' dimensions. You can still wireless charge your Galaxy S21 Plus while the phone is safe and secure inside the Pathfinder casing.

9. Kate Spade New York Protective Case for Galaxy S21 Plus

A Galaxy S21 Plus case for fashionistas


Size: 6.5 x 3.2 x 0.39 inches
Weight: 3.84 ounces
Colors: Clear (with Hollyhock Floral Pattern), Pink Glitter
Materials: Plastic

The Kate Spade New York name means you're going to get a gorgeous design, and this Galaxy S21 case doesn't disappoint. Wether you prefer the glittery pink hardshell case or the clear version with its floral pattern, the Kate Spade New York Protective Case elevates the look of your Samsung phone.

But don't ignore the "Protective" part of this case's name. The phone features shock resistant bumpers to prevent damage from drops, and a co-molded urethane design adds to the durability. Your Galaxy S21 Plus should be able to survive 6-foot drops when it's inserted inside this Kate Spade New York-designed case.

Arae Case for Galaxy S21 Plus

10. Arae Case for Galaxy S21 Plus

Best Galaxy S21 Plus case with a stand


Size: 7 x 4 x 0.6 inches
Weight: 2.82 ounces
Colors: Black, Wine Red
Materials: PU leather

There is no task the Arae Case for the Galaxy S21 Plus can't handle. Want a stylish case for your phone? The Arae Case comes in both black and a retina-shocking Wine Red color that will help you put a distinctive stamp on your S21 Plus. Need to carry around cards and cash? You can stash up to four ID and credit cards into slots on the case. Want a stand to prop up your phone? The Arae Case offers that, too — perfect for when you want to kick back and watch a movie on the device's 6.7-inch OLED display.

That functionality comes at a cost, as the Arae Case is among the bigger Galaxy S21 Plus cases we've looked at. But that's a trade-off a lot of people will be willing to make for a multitasking accessory that costs less than $20.

Mous Limitless 3.0 for Galaxy S21 Plus

11. Mous Limitless 3.0

The best Galaxy S21 Plus case for extra hardware features


Size: 166.34 x W: 80.4 x 12.66mm
Weight: 57 grams
Colors: Aramid Fiber, Bamboo, Walnut
Materials: Poly-carbonate, TPU, microfiber

Mous has packed this case with features. The company's "AiroShock" construction helps prevent damage caused by drops while adding only 2.2mm to the thickness of the phone itself. It also features the all-important raised edge around the display to avoid scratches with the display face-down. And if that wasn't enough, there's storage for two SIM cards on the inside if you need to swap your number in a pinch.

Being a Limitless case, you're able to access Mous' proprietary range of magnetic accessories, meaning you're essentially getting Apple's MagSafe feature, but on your Samsung phone. The range includes card wallets, a car vent mount, a suction cup mount, but if that doesn't appeal, the case still works with standard Qi-compatible wireless chargers.

13. Samsung S-View Cover

The best Galaxy S21 Plus case for extra software features


Size: 6.81 x 3.39 x 0.75 inches
Weight: 3.98 ounces
Colors: Black, pink, violet, gray
Materials: Plastic

Samsung has given you a good reason to stay on-brand by buying the S-View cover case for your S21 Plus. The plastic window on the side of the case works with the phone to display notifications and other important information without you needing to open the phone. You can control your music, check your battery or answer a call all without opening the front cover.

The inclusion of the front cover and raised areas around the rear cameras means this case should prevent the majority of scratches you might encounter. It's great if you're concerned about longevity too as the whole case features an anti-microbial coating to prevent the case from getting worn down.

What to look for in a Samsung Galaxy S21 Plus case

The first thing to do when you're shopping for a Galaxy S21 Plus case is to make sure you're getting one that will fit your phone. Samsung's Galaxy S21 lineup comes in three different sizes, and as nice as the cases for the 6.2-inch S21 and 6.8-inch S21 Ultra are, they're not going to fit your 6.7-inch Galaxy S21 Plus.

After that, finding the best Samsung Galaxy S21 Plus case is really a matter of identifying what you're looking for and making sure a case meets your specifications. If you like wallet cases, make sure that any potential S21 Plus cases you're considering have slots for carrying cash and cards. If drop protection is important, check out what the case maker promises in terms of drop testing.

You're also going to want a case that allows you to make the most of the Galaxy S21 Plus' features. For instance, if you plan on wirelessly charging your phone, it would be best to get a case that works with wireless charging pads. You'll also want to make sure your Galaxy S21 Plus case offers easy access to the phone's ports and buttons.

What is the best protective Galaxy S21 phone case?

The UAG Pathfinder and Otterbox Symmetry are two tough Galaxy S21 cases, and should suit your need for protection. There's also the Spigen Slim Armor case if you want something a little less chunky that's still focused on keeping your phone from harm.

What is the best thin case for Samsung Galaxy S21 Plus?

As you might expect from the name, the Totallee Super Thin is a great case for the Galaxy S21 Plus that doesn't add much bulk to the phone's profile. Samsung's own Kvadrat Cover is pretty skinny too.
