The best iPhone 15 lineup case comparison comes down to this: the iPhone 15 (6.1-inch), iPhone 15 Plus (6.7-inch), and iPhone 15 Pro Max (6.7-inch) each have a Gorilla Cases waterproof case rated IP68 to 6.6 ft (2 m) for up to 1 hour, and each has a screw-secured rugged aluminum case with 0.5 mm raised edges. Pick waterproof for water and wireless charging, and pick aluminum for maximum impact protection.
Gorilla Cases offers matching case styles across the iPhone 15 lineup, so this iPhone 15 case comparison is easy to make. Welcome to the Gorilla Family.
Why an iPhone 15 Lineup Case Comparison Matters in 2026
The iPhone 15, iPhone 15 Plus, and iPhone 15 Pro Max look alike from a distance, but their sizes and cameras differ. A case that fits one will not fit another, so an iPhone 15 case comparison has to be model by model.
The iPhone 15 measures 6.1 inches, while the iPhone 15 Plus and iPhone 15 Pro Max both have 6.7-inch displays. The Plus and Pro Max share a screen size, but their bodies and camera modules are different, and cases are not interchangeable.
Buying the wrong case is the most common mistake we see. This guide shows which Gorilla Cases style suits each phone and how the three compare.

Waterproof Versus Aluminum: How to Decide
The waterproof case is a snap-on sealed enclosure. It is thinner, lighter, and cheaper, and it lets wireless charging pass through the back.
The aluminum case is a bolted metal bumper over silicone. It is heavier and costs more, but it gives you screw-secured armor that cannot pop off in a fall.
Neither case is best for everyone. If you swim, paddle, or work in rain, the sealed case wins, and if you drop your phone on concrete, the aluminum case wins.
How the Three iPhone 15 Models Differ for Case Buyers
Size is the first difference. The iPhone 15 is the most pocketable at 6.1 inches, while the Plus and Pro Max are larger 6.7-inch phones that need bigger, heavier cases.
Cameras are the second difference. The iPhone 15 and iPhone 15 Plus have dual-lens modules, and the iPhone 15 Pro Max has a triple-lens module, so the camera cutout and raised rim are different on each case.
Materials are the third. The iPhone 15 Pro Max has a titanium design, which is why many owners like the clear back of the waterproof case that shows it off.
Who Should Pick Which iPhone 15 Case
Choose the iPhone 15 waterproof case if you want a slim pocketable seal for a 6.1-inch phone. Choose the iPhone 15 Plus waterproof case if you carry the big phone to the beach or pool.
Choose the iPhone 15 Pro Max waterproof case if you want the widest color choice and wireless charging. Choose any rugged aluminum case if your phone lives in a truck, a job site, or a backpack on the trail.
If you are torn, ask whether water or impact is the bigger threat. Water points to the sealed case, and impact points to aluminum.
Illustrative Use Scenario
Here is an illustrative example, not a customer review. Imagine a family with three iPhone 15 models: one parent has the iPhone 15, one has the iPhone 15 Plus, and a teenager saves for the iPhone 15 Pro Max.
The parent with the iPhone 15 Plus spends weekends at the lake, so a waterproof case fits. The parent with the iPhone 15 drives a delivery route, so an aluminum case suits that job.
The family orders each case by exact model, and the cutouts line up on day one. That model-by-model match is the whole point of this iPhone 15 case comparison.
A month later, the teenager gets the iPhone 15 Pro Max and picks the waterproof case in blue trim. The family keeps the spare screws from the aluminum kits in one shared drawer.
Protection Tips for Any iPhone 15 Lineup Case
- Confirm your exact model before ordering, because the three phones are not interchangeable.
- Test a waterproof case in plain water with the phone powered off before a real swim.
- Rinse a waterproof case in fresh water after salt or chlorine exposure.
- Tighten aluminum case screws snugly and recheck them monthly.
- Charge by cable with an aluminum case, since metal can block wireless charging.
- Clean cases with mild soap and a damp cloth, and skip alcohol wipes.
- Keep the spare screws in a safe drawer.
What Is in the Box and How to Install
Waterproof cases arrive as a two-piece enclosure that clamps together around the phone. Aluminum cases arrive with the frame, a screwdriver, two spare screws, and a cleaning kit.
Clean the phone, seat it in the case, and close or bolt the frame. Test every button and port, and test the seal in water only with the phone powered off.
