Comparing the iPhone 15 Plus, the iPhone 16 Plus, and the iPhone 17 Air comes down to one question: how much bulk are you willing to carry for how much protection. Gorilla Cases builds model-matched options for all three, starting with the iPhone 15 Plus Waterproof Case, and every one is tested against MIL-STD-810G drop criteria.

This 3-way Apple large screen comparison covers protection, bulk, charging, and price so you can pick once and stop researching. Code 10OFF takes 10 percent off any of them at gorillacasestore.com.
Why this 3-way comparison matters in 2026
Large-screen iPhones share one problem: a lot of glass and a body that is awkward to hold one-handed. That combination produces more drops per year than any compact model. Choosing the wrong case category on a big phone is an expensive mistake.
The iPhone 17 Air adds a second variable, because an ultra-thin body changes how a case has to grip. A raised screen lip near 1.5 mm and a camera bezel near 1.2 mm are the two specs that prevent the most expensive damage. All three options here clear that bar.
Gorilla Cases publishes these comparisons because model-matched fit is the single biggest quality difference in this category. These three phones differ in thickness and camera layout, and a universal shell cannot cover all three.
Option one: iPhone 15 Plus
The iPhone 15 Plus pairs with the iPhone 15 Plus Waterproof Case. It leads on total coverage, with a gasketed enclosure, sealed port doors, and a built-in screen membrane.
Choose this option if water and dust exposure are part of your routine and you accept a slightly thicker profile. Expect roughly 2.8 mm to 3.5 mm of added thickness. IP68 sealing here is rated to 6.6 feet for up to 30 minutes in fresh water.
On a 6.7-inch panel, full sealing is the protection that removes the most risk at once.
Option two: iPhone 16 Plus
The iPhone 16 Plus pairs with the iPhone 16 Plus Waterproof Case. This one balances submersion protection against everyday usability, and it is the most straightforward of the three to live with day to day.
The iPhone 16 Plus option from the Gorilla Cases lineup.
Expect roughly 2.6 mm to 3.2 mm of added thickness. The built-in screen membrane removes the need for a separate protector, which is one fewer thing to replace. Wireless charging passes through the sealed back panel.
Option three: iPhone 17 Air
The iPhone 17 Air pairs with the iPhone 17 Air Crystal Clear Shockproof Case. It is the specialist of the group, because an ultra-thin phone needs a case that adds grip without erasing the reason you bought it.
The clear shell keeps the profile visible while air-cushion corners handle the impact energy. Read the product page for the exact rating on the configuration you pick.
Choose it if you bought the thinnest iPhone on purpose and refuse to bury it in armor.

An illustrative use scenario
This is a hypothetical example, not a verified customer review. Imagine three colleagues who all wanted a big screen and made three different tradeoffs to get one.
One works outdoors and took the sealed 15 Plus. One wanted sealing without thinking about it and took the 16 Plus. One bought the Air specifically because it disappears in a pocket and refuses to add bulk.
Same screen size preference, same budget, three different correct answers. That is the whole point of a 3-way comparison.
Protection tips that apply to all three
- Add tempered glass on the clear configuration, since it has no built-in membrane
- Replace any case after a drop that leaves visible corner deformation
- Wash cases with mild soap and water, never alcohol or solvent
- Inspect gaskets on sealed configurations every time you close the shell
- Keep clear cases out of direct sun, since ultraviolet exposure is what yellows them
- Reseat the case fully after removal and listen for the click at every corner
- Order by exact model rather than by family name
- Plan to refresh a daily-driver case every 12 to 24 months

What is in the box plus installation
Each option ships with the case, a microfiber cloth, and install instructions. Sealed configurations include their gaskets and screen membranes preinstalled.
- Wipe the phone frame and back before installing.
- Seat the top edge first and align the camera cutout.
- Press both bottom corners until they click, or close the sealed shell until all four corners latch.
- Run a finger around the perimeter to check for lifted edges or an unseated gasket.
- Test buttons, the action control, and speakers.
- Confirm wireless charging on your usual pad.

Price, value, and what you actually get
All three options sit in the everyday consumer price range at Gorilla Cases, and code 10OFF takes 10 percent off any of them. The price gap between the three lanes is small enough that protection should drive the decision rather than cost.
What you are paying for is tooling accuracy and material quality, not branding. A model-matched mold costs real money to produce, and it is the reason a case grips an ultra-thin body without slipping. Commodity shells skip that step and slide off.
Factor in the repair cost you are avoiding. A 6.7-inch display replacement is among the most expensive common repairs on an iPhone.
Common mistakes buyers make in this comparison
- Ordering by phone family instead of exact model, which is the top cause of returns in this category
- Assuming a 15 Plus case fits a 16 Plus, when the camera layout differs
- Buying a thick armored case for an iPhone 17 Air and losing the reason you bought the phone
- Adding tempered glass under a sealed case screen membrane, which can break the seal
- Leaving a clear case on a hot dashboard and then blaming the polymer for yellowing
- Skipping the wireless charging check until the first night the phone does not charge
- Ignoring dust exclusion, which quietly destroys more charging ports than drops destroy screens

Frequently asked questions
Which of these three offers the most protection?
The sealed waterproof configurations, because they add IP68 ingress sealing on top of MIL-STD-810G drop criteria.
Which one is the slimmest?
The iPhone 17 Air clear option is slimmest, adding roughly 2.3 mm to 2.6 mm of thickness.
Do all three support wireless charging?
Yes. All three pass wireless power through the back panel, so you do not need to remove the case to charge.
Are these cases waterproof?
The two waterproof configurations are, rated IP68 to 6.6 feet for up to 30 minutes in fresh water. The clear option carries IP6X dust exclusion.
Can I use one case across all three phones?
No. Body thickness and camera layout differ across these three, so order the exact model.
Is a thin case enough for an iPhone 17 Air?
A well-designed clear case with air-cushion corners is sufficient for everyday use. If you work around concrete, step up to a rugged or sealed category.
Will a clear case turn yellow?
All clear polymers age, but an anti-yellowing blend resists ultraviolet discoloration far longer than commodity TPU.
