The Gorilla Cases iPhone 17 Pro Max waterproof case and the Gorilla Cases Galaxy S26 Ultra waterproof case are both IP68-certified to 10 meters for 60 minutes in 2026 — but the two waterproof cases face fundamentally different engineering challenges due to the different chassis designs of Apple's Titanium Pro Max and Samsung's Titanium Ultra. Here is the complete Gorilla Family comparison for the waterproof iPhone 17 Pro Max case vs waterproof Galaxy S26 Ultra case in 2026.
The Devices: iPhone 17 Pro Max vs Galaxy S26 Ultra Waterproof Engineering
The iPhone 17 Pro Max (6.9-inch, 227g, Titanium Grade 5 frame, ceramic shield front, textured matte glass back) ships with Apple's IP68 rating to 6 meters for 30 minutes. The Galaxy S26 Ultra (6.9-inch, 218g, Titanium-reinforced Armor Aluminum frame, Corning Gorilla Glass Victus 3 front and back) ships with Samsung's IP68 rating to 6 meters for 30 minutes. Both flagships share the same Apple-Samsung IP68 baseline — and both Gorilla Cases waterproof cases double this to 10 meters for 60 minutes through purpose-engineered dual O-ring sealed construction.
The engineering difference: the iPhone 17 Pro Max has Apple's Action Button and Control Center slider as additional chassis penetrations requiring O-ring sealing; the Galaxy S26 Ultra has its built-in S Pen slot as the unique sealing challenge. Sealing the S Pen slot for waterproof use requires a spring-loaded TPU plug in the Gorilla S26 Ultra waterproof case — the S Pen is not accessible when the waterproof case is in sealed waterproof mode.
iPhone 17 Pro Max Waterproof Case Specifications
Shell: dual-layer optical-grade PC inner 0.8mm + TPU perimeter bumper 1.5mm. Port seals: dual O-ring per port including USB-C, Action Button, and Control Center slider. Camera window: optical-grade PC 1.0mm, rated distortion-free to 15m depth for the quad-camera system. Waterproof rating: IP68, 10 meters for 60 minutes. Drop rating: MIL-STD-810G, 26 drops from 1.8m. Weight added: 48g. MagSafe: N52 ring, 1,500g pull force; reseat all port covers after charging.
Galaxy S26 Ultra Waterproof Case Specifications
Shell: dual-layer optical-grade PC inner 0.8mm + TPU perimeter bumper 1.6mm (slightly thicker to accommodate S Pen slot plug mechanism). Port seals: dual O-ring per port including USB-C and speaker grilles; spring-loaded S Pen slot TPU plug. Camera window: optical-grade PC 1.0mm for the 200MP ProVisual Camera Engine array, distortion-free to 15m. Waterproof rating: IP68, 10 meters for 60 minutes. Drop rating: MIL-STD-810G, 26 drops from 1.8m. Weight added: 52g. Magnetic: 1,500g ring for Samsung magnetic ecosystem and MagSafe adapter compatibility.
Head-to-Head: Which Waterproof Case Fits Your Flagship?
S Pen access underwater: The Galaxy S26 Ultra waterproof case seals the S Pen slot with a TPU plug — the S Pen is NOT accessible in sealed waterproof mode. Remove the waterproof case to use the S Pen; the sealed case prioritizes water protection over stylus access. This is a fundamental limitation of waterproofing the S26 Ultra's S Pen slot and applies to all waterproof cases for the S26 Ultra — not a Gorilla Cases limitation specifically.
Camera performance underwater: Both cases use optical-grade PC camera windows rated to 15m depth. The iPhone 17 Pro Max's quad-camera optical zoom chain provides excellent macro underwater imaging; the Galaxy S26 Ultra's 200MP sensor delivers more native resolution but requires more light due to smaller per-pixel well depth. Both waterproof cases enable underwater photography at consumer snorkeling depths (1-10m); professional underwater imaging at 10m depth benefits slightly from the iPhone's optical design characteristics in low-ambient light conditions.
Weight comparison: iPhone 17 Pro Max + waterproof case = 275g (227g + 48g); Galaxy S26 Ultra + waterproof case = 270g (218g + 52g) — nearly identical total carry weight for the same waterproof protection level. Both include buoyant foam wrist lanyards to keep the sealed phone at the surface during water activities.
