The Direct Answer for the Gorilla Family
If you own any A13 Bionic iPhone and want one case that covers everything, buy the iPhone 11 Waterproof Case with Built-in Screen Protector, an IP68-rated full-body shell tested to 6.6 feet of submersion for 30 minutes. It is the best iPhone 11 waterproof case 2026 for anyone who works outdoors, and Gorilla Cases offers matching builds for the Pro and Pro Max sizes so the whole household can standardize on one design.
If you prefer a slimmer profile over full submersion, the iPhone 11 Aluminum Metal Case gives you a machined aluminum alloy bumper with a shock-absorbing inner layer. For the largest phone in the family, the iPhone 11 Pro Max Aluminum Metal Shockproof Slim Case keeps the 6.5-inch handset manageable in one hand. Those three cases anchor the entire comparison below.
Why Case Choice Still Matters for These Three Phones in 2026
The iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max all launched in 2019 and all run the same A13 Bionic chip. Seven years later they are still fast enough for messaging, navigation, streaming, and photography. What has changed is the cost and difficulty of repair.
Apple no longer sells first-party parts for these models at the volume it once did. A cracked rear glass panel on an iPhone 11 Pro Max can now cost more than the phone is worth on the resale market. That single fact is the strongest argument for a serious iPhone 11 Pro Max rugged case in 2026.
Battery health is the second factor. An original A13 Bionic battery that has never been replaced is almost certainly below 80 percent capacity by now. Heat accelerates that decline, so the case you pick should vent well rather than trap warmth against the chassis.
The third factor is seal integrity. All three phones shipped with IP68 ratings, but those ratings apply to a factory-fresh device. Adhesive gaskets dry out, so a case that provides its own IP68 barrier restores protection the phone itself has quietly lost.
Head-to-Head Breakdown of All Three Devices
The iPhone 11 measures 150.9 by 75.7 by 8.3 millimeters and weighs 194 grams. It carries a 6.1-inch Liquid Retina LCD and a dual-lens square camera island in the upper left corner. That camera island is the smallest of the three, which means an iPhone 11 case can use a shallower camera lip.
The iPhone 11 Pro measures 144.0 by 71.4 by 8.1 millimeters and weighs 188 grams. It is the compact member of the trio with a 5.8-inch Super Retina XDR OLED panel. Its triple-lens camera island is physically larger than the iPhone 11 island even though the phone is smaller, so an iPhone 11 Pro case has to devote proportionally more surface area to the camera cutout.
The iPhone 11 Pro Max measures 158.0 by 77.8 by 8.1 millimeters and weighs 226 grams. It has a 6.5-inch OLED display and the same triple-lens island as the Pro. At 226 grams it is the heaviest of the three, and that mass matters enormously for drop physics.
Heavier phones hit the ground with more kinetic energy. A 226-gram iPhone 11 Pro Max falling from waist height delivers roughly 17 percent more impact energy than a 194-gram iPhone 11 from the same height. That is why the iPhone 11 Pro Max rugged case category leans harder on thick TPU corner bumpers than the standard iPhone 11 case category does.
Case fit is not interchangeable across these three. The iPhone 11 and iPhone 11 Pro differ by nearly 7 millimeters in height and 4 millimeters in width. The camera islands are different sizes and different shapes, so a Pro case will never seat correctly on a standard iPhone 11.

Who Each Phone Is For
The iPhone 11 is for the practical owner who wants a large, bright screen without paying Pro prices. It is the most common of the three on the used market, which also makes it the most common candidate for a hand-me-down phone. A tough iPhone 11 case is the right call for a teenager or a jobsite second phone.
The iPhone 11 Pro is for people who genuinely want a small phone. At 144 millimeters tall it slips into pockets that the Pro Max cannot. A slim aluminum iPhone 11 Pro case protects it without erasing the compact advantage that made you keep it.
The iPhone 11 Pro Max is for media watchers, drivers, and anyone who values screen area above all else. Browse the full iPhone 11 Pro Max Cases collection to see every fit we stock. If you want a deeper dive on a single model, read our guide to the best iPhone 11 Pro Max rugged case in 2026.
Tech Specs for All Three A13 Bionic iPhones
All three phones share the A13 Bionic system on a chip with a six-core CPU and a four-core GPU. All three support Qi wireless charging at up to 7.5 watts, and none of them contain MagSafe magnets. That last point is critical when you shop for a case, because a MagSafe ring in the case will not attach to the phone itself.
The iPhone 11 uses a 3,110 milliamp-hour battery. The iPhone 11 Pro uses a 3,046 milliamp-hour battery, and the iPhone 11 Pro Max uses a 3,969 milliamp-hour battery. The Pro Max battery is the reason that phone weighs 226 grams.
Display resolutions differ meaningfully. The iPhone 11 runs 1792 by 828 pixels at 326 pixels per inch. The iPhone 11 Pro runs 2436 by 1125 at 458 pixels per inch, and the iPhone 11 Pro Max runs 2688 by 1242 at the same 458 pixels per inch.
Camera hardware separates the standard model from the two Pro models. The iPhone 11 pairs a 12-megapixel wide lens with a 12-megapixel ultra-wide lens. Both Pro models add a 12-megapixel telephoto lens with 2x optical zoom, which is why their camera islands are taller.
Materials in our cases are consistent across the three fits. Gorilla Cases offers thermoplastic polyurethane for shock absorption, polycarbonate for rigidity, and 6061 aluminum alloy on the metal bumper models. Waterproof models add a silicone gasket seal and a built-in touch-sensitive screen membrane.
An Illustrative Use Scenario
The following is a hypothetical example, not a customer testimonial. Picture a landscaping crew leader who still carries an iPhone 11 Pro Max because the big screen makes job maps readable in sunlight. His phone rides in a truck cupholder, gets handled with wet gloves, and occasionally lands on gravel.
In that scenario a slim silicone skin fails within a season. The gravel scratches the rear glass, and moisture creeps past the aging factory gasket around the charging port. An IP68 full-body case with a sealed port cover would solve both problems at once.
Now picture his daughter with an iPhone 11 handed down from a parent. She drops it on tile roughly once a week from about waist height. For her, a MIL-STD-810G rated case with reinforced corner airbags matters more than water sealing does.
Two different phones in the same A13 Bionic family, two completely different case answers. That is the point of a 3-way comparison rather than a single-model review.
Eight Protection Tips for A13 Bionic iPhones
First, always pair a case with tempered glass. The case protects the edges, but only glass stops screen scratches from keys and sand.
Second, check your camera lip depth. Both Pro models need at least 1.5 millimeters of raised bezel around the triple-lens island to keep the glass off flat surfaces.
Third, replace your case every 18 to 24 months. Thermoplastic polyurethane yellows and stiffens with ultraviolet exposure, and a stiff case transmits shock instead of absorbing it.
Fourth, do not rely on the phone factory IP68 rating anymore. Six-year-old adhesive seals leak, so if water is a real risk, use a case that carries its own IP68 barrier.
Fifth, clean the case interior monthly. Grit trapped between the case and the rear glass acts like sandpaper every time you set the phone down.
Sixth, avoid stacking magnets on these phones. None of the three has MagSafe magnets, so a strong aftermarket magnet ring near the top of the chassis can interfere with the compass.
Seventh, remove the case before long wireless charging sessions. Aluminum bumper cases in particular trap heat, and heat is the fastest way to kill an already aging battery.
Eighth, test the seal on any waterproof case before you trust it. Close every port, submerge the empty case in a sink for five minutes, and check for interior moisture.
What Is in the Box and How to Install
A Gorilla Cases waterproof order ships with the front shell, the rear shell, a pre-installed silicone gasket, a lanyard loop, and a microfiber cleaning cloth. Aluminum bumper orders ship with the two-piece frame, the hex key, four screws, and a spare screw. Every order includes a fit card confirming the exact model.
Installation step one is to power the phone down and wipe both the screen and the rear glass with the microfiber cloth. Any dust trapped under a built-in screen membrane will show as a permanent bubble.
Step two is to seat the phone into the rear shell camera-first, aligning the lens island with the cutout before pressing the body down. Forcing the bottom in first is how people crack camera bezels.
Step three is to snap the front shell on starting at one long edge and working around the perimeter. Listen for the click at each corner rather than pressing the middle.
Step four is to verify function. Test the volume buttons, the ring silent switch, the speaker, the microphone, and the charging port before you consider the install finished.
Frequently Asked Questions
Does an iPhone 11 case fit an iPhone 11 Pro? No. The iPhone 11 is 150.9 millimeters tall and the iPhone 11 Pro is 144.0 millimeters tall, and the camera islands are different sizes.
Does an iPhone 11 Pro case fit an iPhone 11 Pro Max? No. The Pro Max is 14 millimeters taller and 6.4 millimeters wider, so a Pro case will not close around it.
Are these phones still waterproof in 2026? Not reliably. The factory IP68 rating was valid at manufacture, but adhesive seals degrade, so treat an unprotected A13 Bionic iPhone as water resistant at best.
What does MIL-STD-810G mean on a case? It is a United States military test standard, and the relevant drop procedure involves 26 drops onto plywood over concrete from 48 inches.
Do these iPhones support MagSafe? No. The iPhone 11 series predates MagSafe, so magnetic accessories only work if the case itself contains the magnet array.
What drop height do Gorilla Cases rugged models handle? Our rugged models are engineered around a 12-foot drop test onto a hard surface, well beyond the 48-inch military baseline.
Which of the three needs a case most? The iPhone 11 Pro Max, because at 226 grams it carries the most impact energy and has the largest, most expensive glass panels.
Will a thick case block wireless charging? Most cases under 3 millimeters of back thickness charge fine at 7.5 watts, but solid aluminum backs will block it entirely.
Is aluminum or TPU better for these phones? Aluminum resists bending and looks premium, while thermoplastic polyurethane absorbs shock better. Hybrid designs combine both.
How do I keep the camera lenses from scratching? Choose a case with a raised camera lip and add individual tempered glass lens protectors on the Pro and Pro Max.
Do you ship to the whole United States? Yes, and shipping within the United States is free on every order.
Is there a discount code? Yes. Use code 10OFF at checkout for 10 percent off your order.
