Apple's Path to Foldable iPhones: The iPhone 17 Air and Beyond

Apple is reportedly making significant strides in the development of foldable devices. Rumors suggest that the company might introduce a foldable MacBook or iPad before launching a foldable iPhone. However, development delays are attributed to Apple’s cautious approach, including waiting for technological advancements like foldable screens with no visible creases, potentially from Samsung. Industry speculation indicates that while a foldable Apple device is inevitable, the company is in no rush to release it.

The upcoming iPhone 17 Air, expected next year, is considered a precursor to Apple’s foldable innovations. Reports suggest Apple is working to create a device between 5mm and 6mm thick, incorporating compromises to achieve this design. The iPhone 17 Air will feature a single rear-facing camera, likely positioned centrally, and an ultra-thin battery, which could lead to reduced battery life compared to other iPhone 17 models. Additional features include a single speaker, Apple’s 5G modem without mmWave support, and no physical SIM card.

Samsung, Apple’s major competitor, is rumored to launch a Galaxy S25 Slim phone to compete with the iPhone 17 Air. The Galaxy S25 Slim might debut before Apple’s release, showcasing ultra-thin designs similar to the Honor Magic V3, which is only 4.4mm thick when unfolded.

While Fold-type foldable phones like the Honor Magic V3 and Samsung Galaxy Z Fold SE are achieving remarkable thinness, Flip-type foldables remain thicker. Samsung’s Galaxy Z Flip 6, for example, measures 6.9mm when unfolded and 14.9mm when folded. Despite this, Flip phones outsell Fold models, partly due to the higher price point of Fold devices.

Apple’s entry into the foldable market is expected to redefine the segment. Given Apple’s annual iPhone sales exceeding 200 million units, a foldable iPhone could make the technology mainstream. Suppliers and manufacturers will need to adapt to Apple’s large-scale production needs. Historically, Apple has used a gradual approach to introducing innovations, as seen with features like Face ID and OLED displays. The iPhone 17 Air is anticipated to refine ultra-thin components such as batteries, chips, and PCBs, paving the way for foldable models.

The iPhone 17 Air will reportedly integrate Face ID within its slim frame and act as a testing ground for parts that will eventually power foldable iPhones. Foldable designs, like an iPhone Flip, will require additional innovations, such as a durable, ultra-thin hinge, while the larger iPhone Fold may offer more design flexibility due to increased internal space.

As Apple lays the groundwork for its foldable devices, competitors like Samsung are likely preparing similar advancements. Both companies’ ultra-thin smartphone initiatives could set the stage for the next generation of foldable technology.
