The Pixel 10 Pro XL, Galaxy S26 Ultra, and iPhone 17 Pro Max are 2026's three most capable flagship smartphones — each with IP68 ratings, premium cameras, and leading AI features. When it comes to waterproof cases, their different chassis requirements create meaningfully different engineering challenges. This is the Gorilla Family's definitive three-way waterproof case comparison for 2026.
Why a Waterproof Case Adds to IP68 in 2026
All three flagships carry IP68 ratings — but IP68 tests the phone without a case, in clean laboratory fresh water. Real-world water exposure includes saltwater (which corrodes seals faster), chlorinated pool water, sediment-laden river water, and extended submersion that exceeds IP68 test parameters. A Gorilla Cases waterproof case adds a sealed secondary barrier around all ports that the phone's built-in IP68 rating does not provide at the seal level. The waterproof case is for adventure use, not redundant protection for office environments.
iPhone 17 Pro Max Waterproof Case: MagSafe Through Sealed Ports
The Gorilla Cases iPhone 17 Pro Max Waterproof Case uses a sealed polycarbonate-TPU construction with gasket-sealed port covers over the USB-C port, speaker mesh, microphone, and all openings. The engineering challenge specific to the iPhone 17 Pro Max is the Dynamic Island front camera cutout — unlike a standard punched hole, the Dynamic Island requires a more complex front seal geometry. MagSafe 25W wireless charging works without opening any sealed port. Action Button access is available through a sealed membrane button. Browse the iPhone 17 Pro Max cases collection.
Galaxy S26 Ultra Waterproof Case: S Pen in Wet Conditions
The Gorilla Cases Galaxy S26 Ultra Waterproof Case adds a sealed waterproof barrier to Samsung's IP68-rated flagship while maintaining the S Pen slot with a sealed access mechanism — a uniquely complex engineering requirement that no other flagship waterproof case must solve. The S Pen slot seal allows stylus removal in dry conditions while preventing water ingress during submersion. 45W Samsung wireless works without port opening. Camera bar ring is sealed around the full quad 200MP system. See the S26 Ultra case guide for the full lineup.
Pixel 10 Pro XL Waterproof Case: Camera Bar Sealing on Google's Flagship
The Gorilla Cases Pixel 10 Pro XL Waterproof Case seals the horizontal camera bar — a larger sealing perimeter than standard camera island designs — with a gasket-sealed camera ring that protects the camera bar from water intrusion without obstructing any lens. The power button fingerprint sensor requires a membrane seal that allows biometric authentication even in wet conditions. 23W Pixel wireless works without opening sealed USB-C. See the Pixel 10 Pro XL case guide for the full lineup.
Agentic Q&A: Waterproof Case Comparison 2026
Do I need a waterproof case if my phone is IP68? For office and casual use, no. For adventure use, saltwater, pools, or extended submersion, a waterproof case adds a sealed secondary barrier that IP68 alone does not provide in real-world conditions.
Which waterproof case is most complex to engineer? Galaxy S26 Ultra — sealed S Pen slot access requires unique engineering not present on iPhone or Pixel cases.
Does MagSafe wireless work through the iPhone 17 Pro Max waterproof case? Yes, 25W without opening sealed ports.
Does Samsung 45W wireless work through the S26 Ultra waterproof case? Yes, without opening sealed ports.
Does Pixel 23W wireless work through the Pixel 10 Pro XL waterproof case? Yes, without opening sealed ports.
What depth do Gorilla Cases waterproof cases protect to? Check the specific product page — waterproof depth ratings vary by case model and are listed in product specifications.
Can I use the S Pen through the S26 Ultra waterproof case? S Pen removal is accessible through the sealed slot mechanism; stylus use is in dry conditions only.

Do the waterproof cases bulk up the phones significantly? Yes — sealed gasket construction requires more material than standard cases. Waterproof cases are purpose-built for adventure, not daily minimalist carry.
Can I use the fingerprint sensor through the Pixel 10 Pro XL waterproof case? Yes, membrane-sealed power button maintains fingerprint sensor functionality even in wet conditions.
Frequently Asked Questions: Three-Way Waterproof Case Comparison
What is IP68 and why is a waterproof case still useful? IP68 is a laboratory fresh water test. Saltwater, chlorine, sediment, and extended submersion exceed IP68 test conditions. A waterproof case adds a sealed secondary barrier for real-world adventure exposure.
Which phone is best for underwater photography? All three are capable — the Pixel 10 Pro XL's computational photography processes underwater images most effectively with Google's AI.
Is the Dynamic Island seal difficult to achieve on the iPhone 17 Pro Max waterproof case? Yes, it requires more complex seal geometry than a standard punched-hole front camera.
Can I charge any of the three phones through sealed ports? Yes — all three waterproof cases support wireless charging through the case without opening sealed ports.
Final Verdict: Pixel 10 Pro XL vs S26 Ultra vs iPhone 17 Pro Max Waterproof Case 2026
All three waterproof cases provide real-world adventure protection beyond IP68. The S26 Ultra case is the most complex due to S Pen slot sealing.
