Across Samsung's last three Ultra flagships, the Galaxy S23 Ultra is best paired with a MIL-STD-810G military-grade drop protection case, the Galaxy S24 Ultra with an IP68 waterproof shell rated to 1.5 m for 30 minutes, and the Galaxy S25 Ultra with a military-grade shockproof case that supports 15 W magnetic wireless charging. All three Gorilla Cases picks share a 12 ft / 3.6 m drop rating and a raised 1.2 mm camera lip, so the decision comes down to sealing versus magnets versus S Pen access.
Good to see you, Gorilla Family. Three Ultra generations, three different right answers. Gorilla Cases offers a matched shell for each, and this guide puts all three side by side.
Why This Samsung Ultra Comparison Matters in 2026
The Ultra line has stayed dimensionally similar across these three generations, which fools a lot of buyers into thinking cases are interchangeable. They are not. Camera island geometry, button placement, and S Pen silo position all shifted enough that a wrong-generation case will not seat correctly.
The other reason this matters is that these three phones are now at very different points in their lives. An S23 Ultra in 2026 is a well-used daily driver, often out of warranty. An S25 Ultra is still the flagship, still expensive to repair, and still worth protecting aggressively.
That gap changes what you should buy. On an older Ultra, maximum armor is cheap insurance with no downside. On a current Ultra, you also care about keeping magnetic accessories and fast wireless charging fully functional.

Galaxy S23 Ultra: Military-Grade Drop Protection
The Galaxy S23 Ultra Military-Grade Drop Protection Case is the value play in this trio. It combines a TPU inner liner with a polycarbonate outer shell, hits MIL-STD-810G, and carries the same 12 ft / 3.6 m drop rating as the newest option. On a phone that is now several years into service, that is exactly the right amount of case.
It leaves the S Pen silo fully open, which matters more on the S23 Ultra than people expect. Anything that makes the pen harder to extract eventually means you stop using it. The raised 1.2 mm camera lip does the usual work of keeping the lens array off tables.
Wireless charging passes through cleanly since there is no metal in the build. This is the case to buy if your S23 Ultra is a workhorse you plan to run for another two years.
Galaxy S24 Ultra: The IP68 Sealed Waterproof Shell
The Galaxy S24 Ultra Waterproof Case is the only sealed option in this comparison. Its IP68 rating covers 1.5 m for 30 minutes of submersion and complete dust exclusion, and it includes an integrated touch-sensitive screen membrane. If you work around water, that single feature outweighs everything else on this page.
Sealing has costs. The case is thicker, the speakers are slightly muffled, and you have to remove the shell to get the S Pen out. That last point is the real dealbreaker for heavy pen users.
What you get in return is a phone that survives things other cases simply do not address. Rain, wet concrete, boat decks, and fine drywall dust all stop being threats. MIL-STD-810G and the 12 ft / 3.6 m drop rating still apply on top of the seal.
Galaxy S25 Ultra: Military-Grade Shockproof With Full Magnet Support
The Galaxy S25 Ultra Military-Grade Shockproof Drop Protection Case is the most complete package of the three. It matches the MIL-STD-810G rating and the 12 ft / 3.6 m drop rating, keeps the raised 1.2 mm camera lip, and passes 15 W magnetic wireless charging at full strength. It also leaves the S Pen silo unobstructed.
The best Galaxy S25 Ultra rugged case 2026 has on the market is the one that does not force a tradeoff, and this is that case. Corner airbags handle impact energy while the TPU plus polycarbonate sandwich keeps the shell from flexing. Nothing about it fights the phone's own features.
Its only real gap is water. If you need sealing on an S25 Ultra, you are choosing a different case entirely, and you should know that going in.
Who Should Buy Which
Buy the S23 Ultra military-grade case if your phone is out of warranty and you want maximum armor per dollar. Buy the S24 Ultra IP68 waterproof shell if moisture or dust is a daily reality and you rarely use the S Pen. Buy the S25 Ultra shockproof case if you want the strongest all-around protection with zero compromise to magnets or the pen.
All three are stocked in the Gorilla Cases Samsung collection with free US shipping. If you are on an older Ultra, our related guide comparing the Galaxy S22 vs S23 vs S24 case lineup covers the previous generation spread.

An Illustrative Use Scenario
Here is an illustrative example, not a verified customer review. Picture a two-truck HVAC company in Ohio where the owner still runs an S23 Ultra and both techs upgraded to newer Ultras. The owner keeps the military-grade drop case because his phone rides on a dashboard and gets dropped in gravel lots.
One tech spends his days in crawl spaces with standing water, so the IP68 waterproof shell on his S24 Ultra is the only sensible option. The other tech mounts his S25 Ultra magnetically in the van and marks up job photos with the S Pen, so the shockproof case is his answer. Same company, same job, three different correct cases.
The lesson is that generation matters less than context. Pick the case for how the phone gets used.
7 Protection Tips for Any Galaxy Ultra
- Add tempered glass unless the case has a membrane. Only the waterproof shell includes one.
- Test any waterproof case empty first. Latch it, submerge it in a sink for ten minutes, and check for moisture.
- Do not force an S Pen through a sealed case. Take the case off instead of prying at the silo.
- Keep the camera lip clear. Trapped grit against a raised 1.2 mm lip will scuff the lens ring over time.
- Re-seat the case after any hard drop. A corner that has popped loose is no longer absorbing energy.
- Rinse salt water immediately. Salt degrades gaskets faster than anything else.
- Do not stack thick magnet wallets under a rugged case. That is how wireless charging coils overheat.
What Is in the Box Plus Installation Steps
The two military-grade cases ship as a single-piece shell with a microfiber cloth and a quick-start card. The IP68 waterproof case ships as a two-piece sealed shell with a lanyard and a gasket care card. Nothing else is required.
- Lock or power down the Galaxy Ultra before starting.
- Wipe the back glass, the frame, and the camera island clean.
- For the military-grade cases, seat the bottom edge first and press the top corners until both click.
- For the waterproof case, lay the phone into the rear half and align the front half squarely.
- Press each of the four latches until it clicks fully closed.
- Test the volume keys, the power key, and the speakers.
- On the waterproof case only, run a ten-minute empty submersion test first.
