Apple’s first foldable iPhone Ultra has made new progress. According to the latest news from Chinese whistleblower Fixed Focus Digital, Apple has sent foldable iPhone prototypes to many telecom operators around the world for testing. It also revealed that the new phone will use a liquid metal hinge design, indicating that product development has entered a more mature stage, and this technology has actually been laid out as early as 15 years ago.

According to Chinese whistleblowersfixed focus digitalThe latest revelation is that the development and mass production of Apple’s first foldable phone, iPhone Ultra, are currently progressing rapidly. The prototype has even been sent to many telecommunications operators around the world for testing, which means that the product may have entered an important verification stage before being launched.

Another key point worthy of attention in this revelation is that the folding iPhone will use a liquid metal hinge. It has been reported in the market that Apple faced hinge durability challenges during the development process of the folding machine. Some hinge designs failed to pass Apple’s high-strength opening and closing test standards, thus affecting product progress.

However, the latest news shows that the hinge is not the main obstacle in the development process. Apple has selected the liquid metal hinge solution as the core of the iPhone folding screen design. At the same time, R&D and production work are progressing rapidly, and the prototype has been sent for testing.

If the news is true, it means that Apple has entered an important preparatory stage before being launched. Generally speaking, mobile phones need to pass the network compatibility testing and certification process of national telecommunications companies before being officially released to ensure that the product can operate normally in different regions.

Why has Apple been laying out liquid metal technology for more than 15 years?

In fact, Apple has had a cooperative relationship with Liquid Metal Technology for many years. As early as 2010, Apple achieved Liquidmetal Technologies Signed an exclusive licensing agreement to obtain the right to use liquid metal technology in the field of consumer electronics. At that time, many people believed that this material might be used in the iPhone body structure design in the future to create thinner and stronger products.

In the past decade or so, Apple’s actual use of liquid metal has been quite limited. The applications are only the SIM card ejection pin that comes with the iPhone and some internal components.

However, in recent years, Apple-related patent documents have repeatedly shown liquid metal hinges and movable structure designs, so the outside world generally believes that this material is expected to play a greater role in folding products.

Liquid metal will become key innovation in iPhone folding hinge

Liquid metal is an amorphous metal alloy that has a higher strength-to-weight ratio than traditional metals and has excellent wear resistance, corrosion resistance and fatigue resistance.

Since foldable mobile phones may need to withstand hundreds of thousands of opening and closing movements during use, the durability and stability of the hinge are particularly important. Compared with aluminum alloy or stainless steel, liquid metal has advantages. In theory, liquid metal can provide better structural strength and service life, and is also expected to further improve the common durability problems of folding devices.

Tianfeng International analyst Ming-Chi Kuo also pointed out as early as 2025 that Apple’s folding iPhone hinge will use liquid metal material to improve durability and reduce screen crease problems, and will be supplied by Dongguan EonTec. However, in the past, supply chain news has never confirmed the final plan, so the outside world still maintains a wait-and-see attitude.

Now, as the product is about to enter the mass production stage, the source of the news once again emphasized that the liquid metal solution has been finalized, which further enhances the credibility of this rumor.

Folding iPhone Ultra rumored to be unveiled at autumn conference as soon as September

The current supply chain generally believes that Apple will launch a mass production plan in July this year and is expected to be released simultaneously with the iPhone 18 Pro series in September.

It is rumored that the first foldable iPhone Ultra will be equipped with a 7.8-inch inward folding screen and a 5.5-inch outer screen, and will be equipped with TSMC’s 2-nanometer process A20 Pro chip, as well as Apple C2 modem, Touch ID fingerprint recognition, dual-lens main camera system, and vapor chamber cooling technology. The iPhone Ultra is expected to be priced from about US$2,000.
