Why the Waterproof iPhone 7 Plus Case (Black) Is Essential for Outdoor Adventurers and Everyday Klutzes
Picture your iPhone 7 Plus slipping out of your hand at the edge of the lake dock — and you calmly fishing it out, wiping it off, and finishing your photo. That is the whole point of this case. It wraps your iPhone 7 Plus (2016, 5.5-inch Retina display) in a fully sealed, two-piece polycarbonate shell with a shock-absorbing TPU liner and a built-in screen membrane, rated IP68 waterproof to 6.6 ft / 2 m for up to 1 hour. Built for kayakers, beach vacationers, construction workers, parents of pool kids, and anyone who refuses to retire a perfectly good phone, this is the best iPhone 7 Plus waterproof case for people who actually take their phone outside. The Gorilla Family does not wait out the weather — and now your iPhone 7 Plus does not either.
Key Features
- Stealth black finish: matte black shell with a scratch-resistant coating that hides scuffs and fingerprints.
- Premium materials: rigid polycarbonate front and back frames, impact-absorbing TPU gasket, and an ultra-clear PET screen membrane.
- Case type: full-body sealed waterproof case with snap-together front and back halves — no tools needed.
- IP68 waterproof seal: submersible to 6.6 ft / 2 m for up to 1 hour; also blocks dust, sand, dirt, and snow.
- Sealed port covers: hinged latches over the Lightning port and mute switch keep water out while staying easy to open with a fingernail.
- Screen protection: built-in touch-sensitive membrane covers the entire display and keeps Touch ID fully functional.
- Camera protection: optically clear lens window shields the 12 MP dual-tone flash camera without blurring shots.
- Drop protection: survives drops from 6.6 ft / 2 m onto concrete thanks to the shock-spreading TPU perimeter.
- Charging compatibility: charges normally with most Lightning cables through the port cover; the iPhone 7 Plus does not support Qi wireless charging, and this is not a MagSafe case.
- Grip texture: ribbed side rails keep the case planted in wet or gloved hands.
- Compatibility: fits the Apple iPhone 7 Plus (2016, 5.5-inch) ONLY. It does NOT fit the iPhone 7, iPhone 8, iPhone 8 Plus, iPhone 6 Plus, iPhone 6s Plus, or iPhone SE.
Materials Explained — What Polycarbonate and TPU Actually Feel Like
Polycarbonate is the same rigid plastic used in bike helmets and aircraft cockpit windows. Here it forms the front and back shells, giving the case its structural backbone — it will not flex, warp, or pop open when the case takes a hit or gets squeezed at the bottom of a backpack.
TPU (thermoplastic polyurethane) is the flexible, rubbery material you find in running shoe soles and hockey puck rims. In this case it forms the perimeter gasket that does double duty: it absorbs drop impact like a shock absorber and compresses to create the watertight seal that earns the IP68 rating.
The screen membrane is an ultra-clear PET film, thin enough that swipes, taps, and Touch ID presses feel almost identical to bare glass. Altogether the case weighs about 2.9 oz (82 g) and adds roughly 3 mm of thickness — genuinely light for a case that lets a 2016 phone swim like a 2026 flagship.

Real-World Use Cases
- The Kayaker: clips the phone into a deck bag and shoots rapids photos knowing a capsize means a rinse, not a replacement.
- The Beach Vacationer: takes poolside photos and sandy boardwalk videos without sand grinding into the Lightning port.
- The Construction Worker: drops the phone off a 6 ft ladder onto concrete dust, picks it up, and gets back to the punch list.
- The Parent of Pool Kids: films cannonballs from the pool steps without flinching at every splash.
- The Practical Keeper: still loves the iPhone 7 Plus and wants it protected well enough to last several more years.
Feature-to-Benefit Mapping
| Feature | Benefit |
|---|---|
| IP68 sealed design | Submersible to 6.6 ft / 2 m for 1 hour — rain, pools, and lakes stop being emergencies |
| TPU shock gasket | Survives 6.6 ft / 2 m drops onto concrete without cracking the phone |
| Built-in screen membrane | Full display coverage with working Touch ID — no separate protector to buy |
| Latched port covers | Lightning port stays dry and free of sand, lint, and pocket grit |
| Ribbed grip rails | Fewer drops in the first place, even with wet or gloved hands |
Step-by-Step Installation Guide
- Clean your iPhone 7 Plus with a microfiber cloth and make sure the phone and case interior are completely dry.
- Unsnap the front frame from the back shell and inspect the TPU gasket for dust or lint — wipe it if needed.
- Lay the phone into the back shell, aligning the camera with the lens window and the buttons with the case covers.
- Press the front frame on, working around all four edges until every snap clicks and no gaps remain.
- Test the screen, Touch ID, buttons, and speakers — and before any swim, do a 30-minute submersion test with a paper towel inside the empty case.
Troubleshooting and Tips
- Screen feels less responsive after installation? Press gently around the display edges to release trapped air between the membrane and the glass — sensitivity returns immediately.
- Buttons feel stiff the first week? That is the seal breaking in; press each button a dozen times and the action loosens noticeably.
- Sound slightly muffled on calls? The acoustic membranes need a few days to settle; speakerphone is unaffected.
- Fog inside after a temperature swing? Open the case, let both halves air-dry fully, and reinstall — never seal a damp phone inside.
- Cleaning after salt water or sunscreen? Rinse the sealed case under fresh water and towel dry. Avoid alcohol wipes on the coated finish — they can dull the matte black surface.
FAQs
Which phones does this case fit?
It fits the Apple iPhone 7 Plus (2016, 5.5-inch display) only. It does NOT fit the iPhone 7, iPhone 8, iPhone 8 Plus, iPhone 6 Plus, iPhone 6s Plus, or iPhone SE — their button and camera positions differ, which would break the waterproof seal.
What comes in the box?
The two-piece waterproof case in black with the screen membrane and gaskets pre-installed, plus a quick-start guide with sealing and testing instructions.
Is it really waterproof, or just splash-resistant?
It is rated IP68 — fully submersible to 6.6 ft / 2 m for up to 1 hour when correctly sealed. That covers pools, lakes, rain, and accidental dunks. It is not intended for sustained deep diving.
Does wireless charging work with this case?
The iPhone 7 Plus itself does not support Qi wireless charging, so nothing is lost — and this is not a magnetic case and does not add MagSafe. Charge through the sealed Lightning port cover with most standard cables.
What is the drop protection rating?
The case is drop-tested to 6.6 ft / 2 m onto hard surfaces. The TPU perimeter spreads impact energy away from the glass and the raised edges keep the screen and camera off the ground.
Does Touch ID still work?
Yes. The membrane is thin enough that the fingerprint sensor reads through it. If recognition feels slow, re-register your fingerprint with the case installed.
Are the buttons and ports accessible?
Yes — the sleep/wake and volume buttons have sealed press-through covers, and the Lightning port and mute switch sit behind latched waterproof doors you can open in seconds.
Can I add my own glass screen protector?
No need — the screen membrane is built in. Adding tempered glass underneath would break the seal and reduce touch sensitivity.
Will it muffle the speakers or microphone?
Slightly, by design — sound passes through waterproof acoustic membranes. Call quality remains clear, and the effect fades as the membranes break in.
Does it have a lanyard or strap option?
There is no built-in lanyard hole on this model; it is designed as a sealed handheld case. Pair it with a floating strap pouch for boating if you want extra insurance.
Will the black finish fade or peel?
No — the color is molded into the polycarbonate, not painted on, so it cannot peel, and UV-stable resin keeps it from chalking in the sun.
Is it professional enough for the office?
Yes. The matte black, squared-off look reads as purposeful gear, not a toy — it sits flat on a conference table and slides into a laptop bag easily.
Is this a good gift?
Excellent — it is a practical pick under $50 for anyone still running an iPhone 7 Plus, and free 30-day returns make sizing risk-free for the giver.
Can I take underwater photos with it?
Yes, down to 6.6 ft / 2 m. The capacitive screen will not respond under water, so set the camera first and use the volume button as a shutter.
What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all iPhone 7 Plus cases. If the case doesn't fit your iPhone 7 Plus or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.
