Based on this review alone: buy it if you care about inner display has nano-texture coating that significantly cuts down reflections — just accept very expensive, starting at $2,000 and going up to $3,199.
The reviewer found the iPhone Duo to be a surprisingly polished and complete foldable experience for a first-generation product, exceeding initial expectations. However, despite its innovative design and features, the reviewer concludes it's not the new iPhone they would recommend most people buy, suggesting the Pro models are a better choice for the majority.
This review provides a hands-on look at the iPhone Duo, Apple's first foldable smartphone, and the iPhone 18 Pro and Pro Max. It covers the Duo's design, displays, software features, build quality, camera system, and user experience, comparing it to other foldables and previous iPhone models. The reviewer also briefly details the upgrades in the 18 Pro models, focusing on performance, battery, and the Dynamic Island.
The iPhone Duo delivers Apple's most complete and polished foldable experience to date, surprising the reviewer with its refined design and software. Its inner display features a nano-texture coating that drastically reduces reflections and an almost invisible crease, surpassing competitors. Apple has meticulously refined the user experience with fluid animations, seamless app handoffs between screens, and iPad-style layouts on the inner display. However, the outer screen lacks anti-reflective treatment, the under-display inner camera suffers from poor quality, and the overall camera system is a downgrade from Pro models. If you seek a first-generation foldable that feels exceptionally polished in both hardware and software, the iPhone Duo is a strong contender, particularly for productivity and immersive media. If cutting-edge camera performance and comfortable one-handed usability are paramount, other iPhone Pro models would be a more suitable choice.

The iPhone Duo begins at $2,000, which is $100 more than Samsung's equivalent. It goes up to $3,199 for the 2 TB storage model.
reviewer_claimpositivet=01:23–01:40
The 5.4-inch outer display is described as pretty great, just as bright, smooth, and sharp as any Pro iPhone screen, but stockier. Apple has kept the icon layout familiar but moved the dock and quick controls to the side.
hands_on_demopositivet=01:52–02:50
The reviewer demonstrates splitting the screen, dragging items between apps, joining apps to behave as a single unit, and the 'flex mode' for secondary controls. They highlight the fluid handoffs between app states and screen orientations.
specification_claimneutralt=03:10–03:40
The frame is made of titanium, and the hinge combines titanium with carbon fiber. When opened, the phone is 5.2 mm thick, making it quite a bit thicker than Samsung's equivalent, but it feels uniquely solid and retains an IP68 rating.
reviewer_claimpositivet=03:55–04:15
The inner display features a nano texture coating that significantly cuts down on reflections, making it "by far, the least reflective display that I've ever seen on a smartphone, period."
visual_inspectionpositivet=04:23–04:50
The crease on the inner display is described as existing "but barely," being "about as invisible as creases get." The reviewer notes it's more noticeable by feel than by sight.
specification_claimpositivet=05:05–05:30
Apple is promising between 31 and 44 hours of battery life for the Duo, depending on the screen being used. This compares favorably to the iPhone 17 Pro's 33 hours.
visual_inspectionnegativet=08:50–09:05
While the inner screen is anti-reflective, the front screen appears to lack such treatment, making it "very prone to glare."
hands_on_demonegativet=09:10–09:35
Due to its width, the iPhone Duo is not completely usable in one hand. Reaching widgets and pulling down Siri felt like an uncomfortable stretch.
reviewer_claimnegativet=10:45–11:15
The inner under-display camera is deemed "diabolical" with "quality sucks." It also has a different texture than the rest of the screen, making it not truly invisible.
specification_claimnegativet=12:00–12:55
The Duo only has two rear cameras (main and ultrawide), lacking the telephoto lens found on Pro iPhones. The camera setup is comparable to the base iPhone 17, offering less detail and natural background blur than Pro models.
reviewer_claimnegativet=13:10–13:45
The Duo uses Touch ID in the side button instead of Face ID due to the form factor. While not hated, the reviewer considers it a step back compared to Face ID, leading to more friction for authentication.
specification_claimpositivet=15:20–15:55
Part of Face ID has been moved under the display, making the Dynamic Island approximately 35% narrower on the iPhone 18 Pro models. This extra space allows for juggling three live activities instead of two.
specification_claimpositivet=16:15–17:25
The A20 Pro chip, built on a new 2-nanometer process, is claimed to offer up to 40% faster performance, longer battery life, and cooler operation. The vapor chamber has three times the surface area of last year's model.
specification_claimpositivet=19:25–19:40
The iPhone 18 Pro Max promises 45 hours of battery life, attributing this to both efficiency improvements and a much larger battery cell.
The iPhone Duo begins at a premium price point of $2,000, which is $100 more than Samsung's equivalent foldable. For the highest storage capacity of 2 TB, the price escalates to $3,199.
The reviewer states that the crease on the iPhone Duo exists but barely, noting it's about as invisible as creases get on foldable phones. While you might feel it slightly when moving your finger across the display, it's not visually prominent thanks to a nano texture coating.
The iPhone Duo's inner under-display selfie camera is described as having "quality sucks" and is a significant weakness. Furthermore, the rear camera system only includes a main and ultrawide lens, omitting the telephoto lens present on Pro iPhones. Its overall performance is compared to a base iPhone 17, indicating a lower quality than current Pro models.
The reviewer found that because of its wide, passport-like form factor, the iPhone Duo is not ideal for one-handed use. Reaching elements like widgets or pulling down Siri often felt like an uncomfortable stretch, implying it requires two hands for optimal interaction.
Due to design constraints, the iPhone Duo does not feature Face ID. Instead, it utilizes Touch ID integrated into the side button for authentication. The reviewer considers this a step back from Face ID, potentially adding more friction to daily use.
The iPhone 18 Pro models are powered by the A20 Pro chip, a new 2-nanometer processor. This chip is expected to deliver up to 40% faster performance, longer battery life through increased efficiency, and cooler operation thanks to a vapor chamber with three times the surface area of its predecessor. The reviewer noted impressive gaming performance.
On the iPhone 18 Pro and Pro Max, the Dynamic Island has been made approximately 35% narrower. This is achieved by moving some Face ID components under the display. The reduced size allows the phone to display and manage three different live activities simultaneously, an improvement over previous models.
75/100 source quality
The iPhone Duo is Apple's first foldable, priced starting at $2,000, and features a 5.4-inch outer display and an inner display roughly twice that size. It offers refined multitasking, a titanium and carbon fiber build, IP68 rating, and a remarkable nano-texture coating on the inner screen that minimizes reflections and makes the crease nearly invisible. While impressive in its polish and software animations, the Duo has drawbacks including an outer screen prone to glare, difficult one-handed use due to its width, and significantly downgraded cameras (especially the inner selfie camera and lack of telephoto compared to Pro models). The reviewer also touches on the iPhone 18 Pro and Pro Max, noting their heavier build, narrower Dynamic Island, the new A20 Pro chip for up to 40% faster performance and improved thermals, and extended battery life.
