Apple has been working toward a foldable iPhone for years, and the device is now widely expected to arrive this fall. The iPhone Ultra is expected to be announced in early September 2026 alongside the iPhone 18 Pro models, reportedly with a book-style fold, a 7.8-inch inner display, and a starting price that would make even Pro Max buyers wince. Here is everything credibly reported so far.
Crease-free display separates it from all competitors
The single biggest technical achievement Apple is said to be claiming is a 7.8-inch inner display with no visible crease. Most major foldables on the market today, including Samsung’s Galaxy Fold series, have a crease running down the center of the screen where the hinge bends. Apple reportedly pursued eliminating it “regardless of cost,” developing a new material property to make it disappear. If the reports hold up and it works in real-world use, this alone would separate iPhone Ultra from every competitor currently on shelves.
The inner display’s size would put it in iPad mini territory. When unfolded, the screen is reportedly wide enough and tall enough to function like a compact tablet, and the 4:3 aspect ratio of the inner display reflects that. This would be a meaningful shift in how the device is used day to day compared to a standard iPhone, and it is the central argument for the trade-offs Apple is said to have made elsewhere in the design.
Design: titanium, sub-5mm thickness, wider cover display
The iPhone Ultra is said to take design cues from the iPhone 18 Pro lineage: a titanium border, aggressively thin profile, and an overall build that has been described by insiders as resembling two iPhone Airs stacked together when folded, but thinner. Unfolded, it reportedly comes in under 5mm, a genuinely remarkable number for a device with a hinge and two display panels.
The outer cover display reportedly measures 5.5 inches, but its proportions would be unlike any other iPhone screen currently sold. It is said to be shorter and wider than a standard iPhone display, a consequence of the book-style fold geometry. The cover display is reportedly fully functional as a standard phone interface, though its unusual aspect ratio would mean some apps feel different than they do on any other iPhone model.
Touch ID power button instead of Face ID
iPhone Ultra is reported to use a Touch ID power button rather than Face ID, the same approach Apple takes on iPad Air and iPad mini. The geometry of a foldable does not leave good real estate for Face ID’s sensor array, so Apple is said to have made the same call it has on thinner iPad models. This would be a structural constraint, not a cost-cutting decision. For anyone coming from an iPhone 15 Pro or later, it would be a meaningful step back in authentication convenience, particularly for masked unlock, Wallet tap-to-pay confirmations, and App Store purchases that have worked hands-free with Face ID since 2017.
Dual 48MP rear cameras, no telephoto lens
The rear camera system is reported to be a 48MP main and 48MP ultra wide. That is it. No telephoto lens, which Apple reportedly attributes to the physical constraints of fitting a foldable hinge and dual-display stack into a sub-5mm body. The hinge mechanism and the two display panels would consume the space where a periscope telephoto module would normally sit. Anyone who relies on optical zoom on the iPhone 17 Pro camera setup would feel this absence. You would be trading optical reach for a bigger screen and thinner body, with reportedly no configuration option that changes that.
Digital zoom would be available as it is on all iPhones, but the quality gap between optical and digital zoom is significant at longer focal lengths. This would be the clearest hardware trade-off in the entire iPhone Ultra package and the most likely reason existing Pro users hold off on upgrading.
A20 Pro chip, C2 modem, vapor chamber cooling
On the inside, iPhone Ultra is reported to run the same A20 Pro chip and C2 modem as the iPhone 18 Pro. Ultra is also expected to get a vapor chamber for thermal management, the same cooling technology Apple first used on the iPhone 17 Pro Max. A vapor chamber is a flat sealed chamber filled with a small amount of liquid that evaporates when it contacts a hot surface, spreads heat across a larger area, then condenses and returns, cycling continuously to keep temperatures stable under load. The foldable form factor generates heat differently than a standard slab phone, and the vapor chamber is reportedly delivering impressive cooling performance in testing. This would matter for sustained workloads on that large inner display, particularly video editing, gaming, and any task that keeps the A20 running at sustained peak performance.
Battery: 4,883mAh split across two cells
The battery is reported to be split across two cells to fit the foldable body: 1,921mAh and 2,962mAh, totaling 4,883mAh. The two-cell design would be a necessary engineering compromise rather than a performance one. The total capacity is said to be competitive with current flagship Android foldables and to sit above what the iPhone 18 Pro Max carries in a standard slab form factor. Real-world battery life at launch will depend heavily on how the large inner display and vapor chamber interact under typical usage patterns, and those numbers will not be available until reviews publish around launch.
Software: iOS 27 with foldable-specific features, no iPadOS windowing
iPhone Ultra is reported to run iOS 27, not iPadOS. When the inner display is open and in use, the device is said not to gain access to iPadOS 26’s full-fledged windowing or Stage Manager features. Apple is reportedly treating the large inner display as an expanded iPhone canvas rather than a tablet interface. iOS 27 is expected to include landscape-optimized layouts and foldable-specific behaviors, and it seems that some iPhone Ultra-exclusive software features will be held back and revealed at the September event. Two main upgrades specific to iPhone Ultra are expected to arrive with iOS 27, though details on those have not been reported ahead of the announcement.
This would be a significant distinction from Android foldables, where the larger inner display typically runs a tablet-optimized shell of the mobile OS with windowed multitasking. Apple’s reported approach keeps the experience unified with iPhone rather than trying to split the difference between iPhone and iPad software.
Price and supply: $2,300, $2,500, extremely limited at launch
Price estimates currently range from $2,300 to $2,500 depending on configuration, with some analysts holding out hope for a $1,999 starting price on a 256GB model. If the reports are accurate, this would be the most expensive iPhone Apple has ever sold.
Scarcity is expected to be the bigger immediate problem. Apple is expected to ship only 0.5 to 1 million iPhone Ultra units in Q3, with total 2026 supply reportedly around 7 to 8 million. The comparison to iPhone X in 2017 is relevant: Apple announced that device in September, began taking pre-orders in late October, and customers who did not pre-order immediately were looking at delivery estimates stretching into December and January. iPhone Ultra appears to be tracking toward a similar pattern. Delivery estimates at launch are expected to run 4 to 6 weeks or longer, scalpers are expected to list them at a 50 to 100 percent premium, and walking into an Apple Store and buying one freely before December looks unlikely. Pre-ordering the moment the window opens may be the only realistic path to getting one this year.
Here’s a recap of all the features expected in this device:

|---|---|
| Inner (main) display | 7.8-inch foldable, crease-free, 4:3 aspect ratio |
| Cover display | 5.5-inch (shorter, wider than a standard iPhone) |
| Form factor | Book-style fold, titanium border, under 5mm thick unfolded |
| Authentication | Touch ID power button (no Face ID) |
| Rear cameras | 48MP main + 48MP ultra wide (no telephoto) |
| Chip | A20 Pro (same as iPhone 18 Pro) |
| Modem | C2 |
| Cooling | Vapor chamber (also used on iPhone 17 Pro Max) |
| Battery | 4,883mAh total, split across two cells (1,921 + 2,962mAh) |

| Price | $2,300-$2,500 (possible $1,999 for 256GB) |
September announcement, staggered shipping
After an announcement in early September, iPhone 18 Pro models are expected to ship first, with iPhone Ultra following later in the fall. Mass production reportedly began at the end of July, which would put the device on track for the September announcement window despite earlier concerns about hinge reliability. The staggered shipping would mean Apple takes pre-orders for iPhone Ultra at the September event but fulfills them over a longer window than the standard two-week post-announcement ship date that applies to the rest of the iPhone 18 lineup.
