Apple is working on a foldable iPhone that will offer long battery life despite its extremely thin design. The focus is not only on the foldable form factor, but also on energy efficiency and optimized hardware. A recent report, based on information from Apple's supply chain, shows how seriously Apple is taking battery performance in conjunction with a slim design.
The concept of a foldable iPhone has been a hot topic for years. Now, there's mounting evidence that Apple has made significant progress in its development. The company remains true to its philosophy: high-quality materials, sleek design, and technical precision. Instead of a quick market launch, the focus is on a well-thought-out product strategy—with the goal of developing a foldable iPhone that's on par with traditional models in terms of battery life, build quality, and performance.
Slim design thanks to revised display driver
A key component of the new iPhone is the Display Driver IC (DDI). This component converts digital signals from the processor into analog signals for the display. Apple is currently working on optimizing this DDI specifically for the foldable iPhone. The goal is a thinner display module that generates less heat and consumes less power. This is especially important for devices with multiple displays, such as the foldable iPhone. The further development of the DDI enables an overall slimmer design without compromising functionality. At the same time, more efficient control of the display helps extend battery life – a key development concern.
Display size, construction and initial technical details
According to several consistent sources, including analysts such as Ming-Chi Kuo and Jeff Pu, as well as leakers such as Digital Chat Station, the foldable iPhone will have two displays. When unfolded, the display measures 7.8 inches, and when closed, 5.5 inches. This puts Apple in the same range as other foldable high-end smartphones. The device will open like a book, similar to Samsung's Galaxy Z Fold, i.e., horizontally rather than vertically like the Z Flip. Apple is also apparently setting new standards in terms of thickness: When opened, the device is said to be just 4.5 mm thick. When closed, the thickness will be between 9 mm and 9.5 mm – significantly slimmer than many current competing models (via Blog Naver).
Camera, housing, sensors: what else is inside
According to Kuo, the foldable iPhone will be equipped with two rear cameras and a front-facing camera. Instead of Face ID, the device will likely use Touch ID via the power button. This move is likely intended to save internal space. The casing is said to be made of titanium, and the hinge is expected to be a combination of titanium and stainless steel. This choice of material promises high stability while maintaining low weight. A high-density battery is also expected, providing more power in a compact design.
Status of development and possible market launch
Jeff Pu reports that the foldable iPhone is currently in the so-called New Product Introduction (NPI) phase at Foxconn. This phase is an integral part of Apple's production planning and indicates that key hardware decisions have been made. Pu and Kuo expect mass production to begin in the fourth quarter of 2026. However, a limited market launch could be possible as early as the end of 2026.
Classification in the context of other iPhone models
Apple's focus on energy efficiency isn't limited to the foldable iPhone. The upcoming iPhone 16e will also be equipped with its own C1 modem for the first time. Apple describes it as the most power-efficient modem ever installed in an iPhone. In internal tests, it delivers good 5G performance while consuming very little energy. The C1 modem is also expected to be used in the iPhone 17 Air, which is considered a particularly thin model. Apple's overall goal is to develop the thinnest possible devices in every product category – without compromising performance or battery life.
The foldable iPhone will be flat, efficient and powerful
Apple is planning a foldable iPhone that's technologically cutting-edge while also focusing on a sleek design and long battery life. The focus on components like the optimized display driver IC and a more efficient modem demonstrates that Apple is focusing on long-term everyday usability rather than short-term showmanship. If all goes according to plan, the first users could hold a foldable iPhone in their hands by the end of 2026 – in a significantly flatter format than anything currently on the market.
