2027 is still a long way to go, but Apple is reportedly preparing a significant redesign for its 2027 iPhone. That will be the device's 20th anniversary, and the company aims to introduce advanced technologies for the user experience.

According to this Korean news media outlet, one of the key developments includes the adoption of a FinFET-based OLED display driver chip (DDI), transitioning from the current 28nm planar process to a 16nm FinFET process. What this means is that this change is expected to improve power efficiency and support the integration of more sophisticated display features.

On top of that, Apple is also exploring the implementation of pure silicon batteries, which replace graphite with 100% silicon in the anode material. This potential change could significantly increase energy density, leading to longer battery life. Additional features under consideration for the 2027 iPhone include under-display cameras and a four-sided curved display, aiming to achieve a bezel-less, full-screen design.

The source reported Apple plans to discuss these display technologies with its OLED suppliers, Samsung Display and LG Display, in the near future. Industry experts note that the symbolic significance of the 20th anniversary may prompt the company to introduce more groundbreaking features in this model, but we shall wait and see.
