Apple’s long-rumored foldable iPhone may finally have a name, and if early leaks are accurate, it could be one of the most significant redesigns in iPhone history. Tentatively referred to as the iPhone 18 Ultra — and previously circulating under the codename iPhone Fold — this device is expected to mark Apple’s official entry into the foldable smartphone market when it’s announced sometime in 2026.
Below is a complete breakdown of the unofficial preliminary specifications currently making the rounds, along with context on what each detail could mean for Apple fans.
Release Timeline: Exp. Announcement 2026
Industry leaks point to an announcement window sometime in 2026, though Apple has made no official statement. As with all unreleased Apple products, this date should be treated as fluid until Apple sends out an actual event invite.
A Foldable Design With a 4.7mm Profile
The headline feature is the form factor itself. Leaked dimensions suggest:
Unfolded: 120.6 x 167.6 x 4.7mm Folded: 120.6 x 83.8 x 9.2mm
A 4.7mm unfolded thickness would be remarkably thin for a foldable, putting Apple in direct competition with Samsung’s Galaxy Z Fold series. The body is rumored to use an amorphous alloy frame, a material choice that could help the hinge area withstand repeated folding while keeping weight manageable.
Display: 7.76″ Foldable Screen Plus a Cover Display
This is where the iPhone 18 Ultra leak gets most interesting. The internal display is rumored at 7.76 inches with a resolution of 1920 x 2713 pixels, translating to a sharp ~428 ppi density and a screen-to-body ratio near 90.6%.
Key display rumors include:
Foldable LTPO OLED panel with 120Hz refresh rate and HDR10+ support Self-healing memory glass technology on the inner display, a first if it materializes A small display crease, which leakers suggest Apple has minimized but not eliminated A separate 5.49-inch cover display (1422 x 2088 pixels) using Ceramic Shield glass for everyday use without unfolding the device
Performance: 3nm Chip and 12GB RAM
The device is expected to run iOS on a 3nm chipset, paired with 12GB RAM across all storage configurations. Storage options are rumored at 256GB, 512GB, and 1TB, with no microSD card slot, consistent with Apple’s long-standing approach to fixed internal storage.
Cameras: 48MP Dual Setup (Specs Marked as Illustrative)
It’s worth noting upfront that the camera details circulating for this device are explicitly labeled illustrative by leak sources, meaning no confirmed camera information is currently available. The rumored setup includes a 48MP wide sensor with sensor-shift OIS and a 48MP ultrawide sensor, plus an 18MP selfie camera duplicated on both the main and cover displays. Video capabilities mentioned include 4K recording up to 120fps, Dolby Vision HDR, and Apple’s ProRes format, though these should be treated as placeholder estimates rather than confirmed hardware capabilities.
Battery: 5500mAh Capacity
A 5500mAh battery is rumored, which would be among the largest in any iPhone to date, likely necessary to power dual displays and a larger chassis. Charging is expected to remain wired plus MagSafe/Qi2 wireless, though leaks suggest the wireless charging may work without traditional magnets, possibly due to the folding mechanism.
Connectivity and Other Features
Other leaked details include Wi-Fi 7 support, Bluetooth 5.3, a side-mounted fingerprint sensor (a departure from Face ID-only authentication on recent iPhones), second-generation Ultra Wideband support, and continued satellite connectivity for Emergency SOS and Messages.
Estimated Price: Around 2200 EUR
Leaks suggest a starting price around 2200 EUR, which would position the iPhone 18 Ultra as Apple’s most expensive iPhone yet, reflecting the cost premium typically associated with foldable display technology.
Should You Trust These Specs?
It’s important to frame all of this correctly: every detail above comes from unofficial, preliminary leaks, and Apple has not confirmed the existence of a foldable iPhone, its name, or any specification listed. The “iPhone 18 Ultra” naming itself is speculative, and the device was previously discussed under the placeholder name “iPhone Fold.” Leak accuracy varies significantly this far ahead of an official announcement, so treat these numbers as a snapshot of current rumors rather than a confirmed product roadmap.
Final Thoughts
If even a portion of these leaks hold up, the iPhone 18 Ultra could represent Apple’s biggest design shift in years, combining a slim foldable body, dual high-resolution displays, and flagship-level internals. For now, the best approach is to follow ongoing leak coverage and wait for Apple’s official confirmation before treating any of these specs as final.
