Leaker: Foldable 'iPhone Ultra' Will Feature Liquid Metal Hinge

Apple's first foldable iPhone will feature an innovative liquid metal hinge and has now shipped prototype units to carriers around the world for testing, the leaker known as "Fixed Focus Digital" today said.


In a new post on Weibo, Fixed Focus Digital said development and production related to the foldable are now "progressing rapidly." The claim arrives one day after the leaker reported that the foldable iPhone would feature vapor chamber cooling.

The liquid metal hinge detail is significant in light of the ongoing debate over the device's production difficulties. Earlier reports from the leaker known as "Instant Digital" attributed manufacturing problems to the hinge failing Apple's quality control standards under prolonged, high-frequency open-and-close testing. Fixed Focus Digital previously pushed back on that characterization, arguing the hinge was not the primary source of difficulty, and today's post appears to position the hinge as a resolved and confirmed element of the design.

Liquid metal is an amorphous metal alloy with a notably higher strength-to-weight ratio than conventional metals, along with superior resistance to corrosion and wear. Apple has used liquid metal in limited contexts before, most notably for the SIM ejector tool included with iPhones and for certain internal components, but its application in a structural hinge mechanism would be a far more demanding use of the material. The foldable iPhone is expected to fold and unfold hundreds of thousands of times over its lifespan, placing exceptional stress on the hinge, and liquid metal's durability properties make it a more capable material than conventional alloys.

Apple's history with liquid metal stretches back over 15 years. In 2010, Apple signed an exclusive deal with Liquidmetal Technologies, receiving a perpetual worldwide license to commercialize the material in consumer electronics. In the years that followed, the company used liquid metal only for minor components such as the SIM ejector tool, with the material proving difficult to scale for larger structural parts. Apple repeatedly renewed its arrangement with Liquidmetal Technologies, and the material has continued to surface in patent filings covering hinges and other moving parts.

Supply chain analyst Ming-Chi Kuo first reported in March 2025 that the foldable iPhone's hinge would use liquid metal, with Dongguan EonTec named as the exclusive supplier of the alloy. A subsequent January supply chain report corroborated the liquid metal hinge plans, but in April Fixed Focus Digital cast doubt on the material choice, claiming Apple was still weighing liquid metal against 3D-printed titanium alloy.

The claim that prototypes have reached global carriers for testing represents a meaningful milestone, suggesting the device is now sufficiently complete to undergo the network compatibility and carrier certification process that precedes commercial launch. DigiTimes reported in April that mass production was planned to begin in July, and Bloomberg's Mark Gurman reported the device remains on track for a September debut alongside the iPhone 18 Pro and ‌iPhone 18 Pro‌ Max, though he noted the timing was not yet final at the time of writing.

The foldable iPhone is expected to feature a 7.8-inch inner display, a 5.5-inch cover display, the A20 chip, the C2 modem, Touch ID in place of Face ID, and two rear cameras, with pricing rumored to start at around $2,000.

Foldable iPad Said to Share Hinge Design With Upcoming iPhone Ultra

Apple is still developing a large foldable iPad despite technical hurdles, and it should feature the same crease-free hinge design as Apple's rumored "iPhone Ultra," its first foldable iPhone expected to launch in the fall.


That's according to Weibo-based Digital Chat Station. The popular Chinese-language leaker implies that Apple's large foldable iPad will create a new market for giant folding tablets, but it's likely to still be some ways off yet.

A report in July last year claimed Apple had decided to pause work on a larger-screened foldable iPad because of development issues, but Bloomberg reported in March that development continues.

According to Bloomberg's previous reporting, Apple wanted to launch the device in 2028, but problems with weight and display technology are likely to cause it to be pushed back until 2029.

The device is believed to have a Samsung-made 18-inch display, and will challenge Apple's long-running tradition of keeping the Mac and iPad as separate devices. Some have referred to it as a foldable iPad, while others have called it an all-display MacBook, but concerns remain about its practicality when it comes to typing.

When closed, the iPad resembles a MacBook, with an aluminum exterior and no outer display. When opened, it unfolds to roughly the size of a 13-inch MacBook Air, but without a physical keyboard. Due to its large display and aluminum chassis, current prototypes weigh about 3.5 pounds, making them considerably heavier than existing iPad Pro models.

An 18-inch OLED foldable display will surely be expensive, too, given that Apple charges $1,299 for the 13-inch ‌iPad Pro. If prices don't come down for components over the next few years, the foldable ‌iPad‌ could cost as much as $3,900. It also sounds like Apple still has work to do to perfect its hinge/crease designs.

Meanwhile, Apple's foldable iPhone, which could take the name "iPhone Ultra," is expected to arrive in the fall alongside Apple's new iPhone 18 Pro and iPhone 18 Pro Max models, barring any last-minute production mishaps. The folding iPhone is said to feature a 5.5-inch display when closed, and a 7.8-inch display when open, plus a super-thin design with minimal crease and a durable hinge.

Apple Planning to Launch Two New 'Ultra' Products in the Next Year

Apple has decided to market two of its new products over the next year as "Ultra" devices, Macworld reports.


Citing sources familiar with the matter, the report claims that Apple's first foldable iPhone will be called the "iPhone Ultra." The device will become the highest end option in the lineup.

The ‌iPhone Ultra‌ will not be considered part of the iPhone 18 iPhone lineup, despite arriving alongside the iPhone 18 Pro and ‌iPhone 18 Pro‌ Max. This would be just like how the iPhone Air is not considered to be part of the iPhone 17 series. Although Apple is hoping to ship the ‌iPhone Ultra‌ alongside the ‌iPhone 18 Pro‌, it may launch a few weeks later and with scarcer availability.

Moreover, Apple is apparently planning to release a "MacBook Ultra" later this year or in early 2027. It will feature an OLED panel and a touchscreen, sitting above the MacBook Pro in the lineup at a "significantly" higher price point. While the device was originally intended to launch later this year, it is now likely pushed back by several months due to memory supply chain shortages.

Apple already offers M-series Ultra chips, the Apple Watch Ultra, and CarPlay Ultra. "Ultra" branding for the foldable iPhone and OLED MacBook was previously rumored by Bloomberg, which added that "AirPods Ultra" could also be on the way.

Foldable 'iPhone Ultra' Could Be Missing These 5 Key Features Despite $2,000 Price Tag

Apple's first foldable iPhone, dubbed the "iPhone Ultra," could be missing at least five key features present on the iPhone 18 Pro models despite its $2,000 price point.


Recent images of dummy models shared by Sonny Dickson and Vadim Yuryev seem to reveal two previously undiscussed missing features of the ‌iPhone Ultra‌: MagSafe and the Action Button.

iPhone dummy units are intended to take the place of real devices for testing purposes, particularly for accessory manufacturers, who seek to mass produce items such as cases prior to the announcement of new devices, which necessitates a high level of accuracy and manufacturing precision.

Both sets of dummy models show that the volume buttons will be located on the top edge of the device, aligned to the right, similar to the iPad mini. This aspect was first rumored by Weibo leaker "Instant Digital," who said that the motherboard is apparently located on the right side of the device. As to not run cables across the screen to the left side for the volume buttons (where they are located on all other iPhone models), Apple is said to have decided to run them directly upwards, which maximizes internal space.

While a power button and volume buttons in their new location are clearly visible on the dummy models, the Action button is curiously missing. This suggests that the ‌iPhone Ultra‌ will be the first iPhone model with no Action button or silent switch. Apple introduced the Action button on the iPhone 15 Pro as a replacement for the silent switch, and it has since come to every available iPhone model.

The images of the foldable iPhone dummy models shared so far have been shown alongside mock ‌iPhone 18 Pro‌ and ‌iPhone 18 Pro‌ Max units. These dupes for the high-end models, like most dummies, clearly show precise indentations for the internal array of ‌MagSafe‌ magnets to help manufacturers obtain correct alignment with their accessories.

Crucially, these indentations are absent on the foldable iPhone dummies, suggesting that the device may not have ‌MagSafe‌. This aspect remains speculative, but at 4.5mm, the ‌iPhone Ultra‌ is expected to be Apple's thinnest iPhone to date by a considerable margin, so it is not implausible that it could be too thin for ‌MagSafe‌.

The ‌iPhone Ultra‌ is believed to be too thin to accommodate Apple's TrueDepth camera array, which is required for Face ID authentication and now located in the Dynamic Island. As a result, Apple is expected to revert to Touch ID on the device. The last iPhone to feature ‌Touch ID‌ was 2022's iPhone SE 3, where it was part of the device's budget offering. The last flagship iPhone with ‌Touch ID‌ was 2016's iPhone 7, so the return of ‌Touch ID‌ as the sole method of authentication on what will be the highest-end iPhone will be unprecedented.

As visible on the dummy models, which corroborate a multitude rumors, the ‌iPhone Ultra‌ is expected to sport only two rear cameras. These are expected to be wide and ultra wide cameras, just like the iPhone 17. Unlike the Pro iPhones, there will be no third camera with telephoto capabilities.

Previous rumors indicate that the ‌iPhone Ultra‌ will also not have a SIM card slot, again just like the iPhone Air, being compatible with eSIM only. As a result, the ‌iPhone Ultra‌ could be missing the following features:


  • ‌Face ID‌/TrueDepth camera array

  • Telephoto camera/third rear camera

  • ‌MagSafe‌

  • Action Button

  • Physical SIM card slot


The ‌iPhone Air‌ lacks Ultra Wide and Telephoto rear cameras, a SIM card slot, and stereo speakers. With a super-thin design, a titanium frame, and a glass back, the ‌iPhone Ultra‌ is expected to be very similar to the ‌iPhone Air‌ in terms of design, and it is possible that similar feature concessions will be present on the device when it launches later this year. There are no indications that the ‌iPhone Ultra‌ will be missing stereo speakers, but it is not out of the question given the other design compromises Apple has chosen to make with the device.

The rumored starting price for the ‌iPhone Ultra‌ varies somewhat, but reports agree that it will not be below $1,999. The iPhone 17 Pro starts at $1,099 and has all of the above missing features, so the ‌iPhone Ultra‌'s compromises could be controversial given its markedly higher price point. The device is expected to launch alongside the ‌iPhone 18 Pro‌ and ‌iPhone 18 Pro‌ Max in the fall.
