TheSamsung Galaxy S23 Ultrais one of the best phones in today’s market. What makes it shine is the powerful Snapdragon 8 Gen 2 processor, ensuring that it runs like a well-oiled machine. But as we all know, accidents happen. While Samsung put a lot of thought into designing this phone with a durable Gorilla Glass Victus 2 screen and a robust aluminum body, it still has its limits when it comes to taking a beating in the real world.
There’s no need to worry. A reliable solution exists to protect your Samsung Galaxy S23 Ultra from the daily wear and tear of everyday life. These robust heavy-duty cases have been specially designed to offer enhanced protection for your phone to make it last longer than it otherwise might. Think of them as a sturdy shield that encases your Samsung Galaxy S23 Ultra against the dark forces of gravity, abrasion and general clumsiness.
Functioning like protective armor for your device, they effectively absorb shocks and impacts that could potentially damage your phone. Whether you unintentionally drop your premium device on a hard surface or it slips and falls down the stairs, these cases are constructed to endure such incidents without passing it on to the S23.
Ringke Fusion X for Galaxy S23 Ultra
The Ringke Fusion X is perfect for people who want adequate impact protection without making the Galaxy S23 Ultra unbearably heavy or thick. The bumpers on all four corners ensure that the kinetic energy from drops is negated to keep your phone free of damage. The only downside is the small lip around the display. It’ll stop scratches but won’t help much if the phone has a hard drop face down.
UAG Monarch for Galaxy S23 Ultra
The UAG Monarch is expensive, but it tries to justify that cost with exceptional build quality. We love how this case looks and feels, and it doesn’t lack in the protection department. The case can withstand any hard drop or knock, surviving drop tests of up to 25 feet. To top it off, a magnet in the case makes your Galaxy S23 Ultra compatible with MagSafe chargers and accessories.
i-Blason Cosmo Series for Galaxy S23 Ultra
The i-Blason Cosmo is one of our favorite cases for good reason. The protection is excellent due to the dissipating kinetic energy, and the built-in screen protector ensures the display is kept scratch-free. The best part is the way it looks. The Cosmo goes above and beyond to stand out in a sea of black TPU rectangles. We love it because there are plenty of designs to choose from, with our favorite being the Swirl, seen in the photo here.
Caseborne V for Galaxy S23 Ultra
The Caseborne V is built Texas tough, surviving drops of 21 feet, exceeding the requirements for military specification. The kickstand can support the phone in portrait and landscape, although it isn’t quite as sturdy as the ones on the Supcase UB Pro. A strong lip surrounds the front of the phone, helping negate display scratches even without a screen protector. And the lifetime warranty that can be activated once the case arrives makes this case stand out from the rest.
Spigen Tough Armor for Galaxy S23 Ultra
Spigen’s Tough Armor lives up to its name thanks to its dual-layer construction. The hard plastic shell sits atop a soft TPU inner layer, and combined, they absorb hard knocks and drops without the S23 Ultra taking any damage. The plastic shell feels comfortable, and the case isn’t too thick despite being so tough. The one area we’ve often marked Spigen down is color choices, but that’s changing for the better.
Poetic Neon for Galaxy S23 Ultra
Heavy-duty cases are bulky, making the already-large Galaxy S23 Ultra unwieldy. The Poetic Neon exists as a middle ground between normal and extreme. While remaining slim, the Poetic Neon is made up of two layers, so it can deal with almost any damage. In terms of protection, the only thing lacking is a port cover, but if you use wired Android Auto or charging, that could be a good thing as it won’t place any additional strain on your cables.
Supcase UB Pro for Galaxy S23 Ultra
The Supcase UB Pro has built a reputation as one of the best heavy-duty cases on the market and is well-earned. The case uses a dual-layer construction to absorb any damage and keep your Galaxy S23 Ultra safe. The addition of port covers and one of the best kickstands we’ve ever used completes the package. You can buy this case with or without a built-in screen protector, and we’ve selected the one without it. A glass one is always better.
Spigen Cryo Armor for Galaxy S23 Ultra
Spigen’s Cryo Armor is a unique and understating offering that feels comfortable in hand. Also, the vented backplate allows the case to passively pull heat out of the phone and dissipate it into the atmosphere. That’s what the marketing says anyway; we’re not entirely sure how effective this is when gaming. Still, these vents look cool, and the case does a stand-up job keeping your phone safe from a drop or impact.
VRS Damda Glide Hybrid for Galaxy S23 Ultra
Available in black or green, the VRS Damda Glide Hybrid encases your Galaxy S23 Ultra in a tough bedding of TPU, ensuring you’ll never have to worry about dropping your mobile ever again. We’re also big supporters of the precision cutouts on this model, which add an extra bit of defense for the S23 Ultra’s camera lenses and ports. But our favorite element is the built-in wallet that can hold up to four cards and includes a sliding shield.
Caseology Parallax for Galaxy S23 Ultra
An example of superb engineering, the Caseology Parallax case looks as good as it protects. The textured sides offer excellent grip even on sweaty hands, and the hybrid material provides 100% protection from drops as low as 4 feet. The finely cut apertures and holes on the sides and back mingle effortlessly with the phone’s own openings and camera module, allowing for easy access to all ports. Moreover, 1.2mm clearance on the front ensures the screen stays protected as well.
Tongate Case for Galaxy S23 Ultra
With seven different colors to choose from, this Tongate case comes with a built-in slider that protects the S23 Ultra’s lenses from dirt and dings when not in use. This is also one of the tougher cases for the S23 Ultra, thanks to the hard PC back cover, soft TPU edges, and the hard front frames with (or without) the integrated screen protectors. We’re also big fans of the fully rotatable belt clip.
FNTCase for Galaxy S23 Ultra
When you need to combine style with top-notch defense, look no further than the formidable FNTCase brand. This awesome Galaxy S23 Ultra case comes in 14 different colors, includes a sliding shield for the camera lenses, and even includes a built-in kickstand that can be used for both portrait and landscape viewing.
Wondering which case is right for you?
There is a fine balance with heavy-duty cases that makes them super tough and durable, but they also make the phone larger. The best ones use the right materials to protect the S23 Ultra without encasing it in something impractical.
Typically, a hard outer shell combines with a more flexible core to stop scratches and dings from making it to the phone from the outside. The trade-off here is that achieving the level of protection requires a specific level of thickness, which is why heavy-duty designs aren’t as elegant as a simple bumper.
All that being said, our top pick is the Ringke Fusion X. It’s slim, but gives great protection with corner bumpers, and it’s comfortable to hold, too. The UAG Monarch is a bit pricey, but looks amazing and offers top-notch protection. It’s like a luxury car for your phone. Lastly, check out the Caseborne V. It’s affordable, offers good protection, has a kickstand, and comes with a lifetime warranty. They’re confident it won’t break.
