The foldable iPhone Duo
The foldable iPhone is the lineup’s genuinely new form factor. Rather than a single fixed screen, it opens from a compact, pocketable size into a larger display, closer to a small tablet than a phone. Closed, it works like a normal iPhone. Opened, it gives you a lot more room to work with.

Which new iPhone is right for you?
The right device comes down to how you actually use your phone, not the spec sheet.
Pick the iPhone 18 Pro if you want a familiar everyday iPhone experience with better battery life and the biggest camera update in years! Choose the iPhone 18 Pro Max if you want more advanced cameras and AI features for better content creation and overall productivity. Opt for the foldable iPhone Duo if you want to try Apple’s new form factor and innovative way of getting the most out of your device.
iPhone 18 Pro design and materials
The biggest leap in the iPhone 18 Pro and iPhone 18 Pro Max comes from the all-new A20 Pro chip, built on advanced 2-nanometer technology. Its redesigned 6-core CPU features two new performance cores and four next-generation efficiency cores, delivering faster speeds, improved power efficiency, and desktop-class responsiveness. A new 7-core GPU boosts graphics performance by up to 40%, while the 32-core Neural Engine doubles AI processing power for smarter, faster on-device experiences. Backed by a 50% increase in memory bandwidth and an advanced vapor chamber cooling system, the A20 Pro is engineered to handle demanding tasks with sustained performance.
The real design story this year is Apple's breakthrough foldable engineering. iPhone Duo pairs the largest display ever on an iPhone with a pocketable form factor, enabled by a precision multi-component hinge, a durable titanium enclosure, and a new display architecture designed to minimize crease visibility while delivering a smooth, seamless experience whether open or closed.
iPhone 18 Pro camera upgrades
The biggest iPhone camera update in years introduces a new 48MP camera and intelligent aperture system that automatically adjusts to lighting conditions. Capture brighter night photos, richer detail, and more professional-looking photos and videos in almost any environment.
Performance and battery
The A20 Pro chip delivers up to 40% faster performance than iPhone 17 Pro and up to 2x the performance of iPhone 16 Pro and older devices. iPhone 18 Pro Max offers up to 45 hours of battery life, while iPhone 18 Pro can reach up to 50% charge in just 15 minutes.
OtterBox cases for the iPhone 18 and iPhone 18 Pro
A new phone deserves a protective case built for it. OtterBox's iPhone 18 lineup has coverage options including the Lumen Series, Figura Series, Defender Series Pro, the Sole Series Pack and the Commuter Series – giving a range of options from slim and clear to genuinely rugged.

The Lumen Series
The Lumen Series keeps things slim without giving up personality. Clear finishes, colors and prints show off your phone, while raised edges, camera plateau coverage on supported devices, scratch resistance and built-in magnets for MagSafe accessories keep it protected. Camera Control stays fully accessible too.

The Figura Series
The Figura Series goes softer and more minimal, with a velvety-soft finish and a slim, flexible profile. It's the pick for anyone who wants their case to feel understated rather than statement-making, without giving up MagSafe compatibility or Camera Control access.

The Defender Series Pro
The Defender Series Pro is built for the days that are hardest on your phone. Tri-layer construction, raised edges, port covers and an all-over textured grip stand up to drops, dust and scrapes, while MagSafe compatibility and Camera Control mean you're not giving anything up for the extra protection.

The Defender Series Pro XT
A folding iPhone needs a case that folds with it. The Defender Series Pro XT is built around the foldable iPhone’s hinge, with rugged hinge protection that moves as the phone opens and closes and lies flat when it’s open.
Grippy edges give you a steadier hold, port covers block out dust and dirt, and built-in magnets keep wireless charging aligned. It's 4X tested to military drop standard (MIL-STD-810G 516.6), built for a device that's still finding its footing in everyday use.

The Lumen Series
For a slimmer option, the Lumen Series brings a clear finish to the iPhone Duo, with raised edges and scratch resistance that protect it without hiding the design. Built-in magnets keep it ready for MagSafe accessories, so you're not trading protection for style.
