Apple's inaugural foldable smartphone, the iPhone Ultra, is anticipated to hit the market in September 2026. The innovative dual-cell battery design of this device was initially unveiled in the fourth beta version of the iOS 27 developer preview, boasting individual cell capacities of 1921mAh and 2962mAh, summing up to a substantial 4883mAh. The system code now encompasses functionality to monitor the health status of multi-cell batteries, enabling independent tracking of each battery's performance. This advancement aids in reducing maintenance costs and enhancing overall battery management.
Previously, code snippets pertinent to foldable devices, such as 'foldState' and 'angleDegrees', were unearthed in the inaugural beta version of iOS 27. These code elements lay the groundwork for interactive adaptations tailored to the foldable form factor, ensuring seamless user experience.
Furthermore, the iPhone Ultra is rumored to sport a bespoke Samsung LTPO OLED flexible display and incorporate a liquid metal hinge mechanism. However, the intricate processing demands of liquid metal, with a mass production yield hovering around 65%, could present a significant hurdle for large-scale manufacturing. This challenge underscores the complexity and innovation involved in bringing this cutting-edge device to fruition.
