Apple appears to be advancing its iPhone 18 lineup with prototype production already underway, according to industry insights. The company is said to be testing multiple variants, including the highly anticipated Pro models, which are rumored to incorporate under-display Face ID—a significant shift from previous iterations.
The focus on prototype development suggests Apple is refining both hardware and software for this year’s lineup, with a particular emphasis on display technology. All four models in the series—including what was previously speculated as an iPhone Air 2—are expected to feature LTPO OLED panels capable of reaching a 120Hz refresh rate, though final specifications could still evolve before mass production.
Pro Models: A New Era for Face ID
The iPhone 18 Pro and Pro Max are likely to stand out with under-display Face ID, eliminating the traditional notch while preserving the functionality of Apple’s facial recognition system. This move aligns with industry trends toward more immersive displays but would mark a first for Apple in its flagship lineup.
Display Sizes and Technical Specifications
While exact details remain under wraps, leaked information points to three distinct display sizes across the lineup: 6.27 inches for the standard iPhone 18 and Pro models, and 6.55 inches for what may be the iPhone Air 2. The Pro Max is expected to feature a larger 6.86-inch panel. All screens are rumored to support Dynamic Island, Apple’s customizable control interface, which has become a staple in recent models.
Performance and Efficiency Considerations
The 120Hz refresh rate across all models suggests Apple is prioritizing smoothness and responsiveness, particularly for tasks like scrolling, gaming, or fluid animations. LTPO (Low-Temperature Polycrystalline Oxide) technology allows the display to dynamically adjust its refresh rate based on content, which could improve battery life without sacrificing performance.
What’s Next?
With prototype production in motion, Apple is likely balancing multiple priorities: refining under-display Face ID for the Pro models, ensuring stability in software integration, and preparing for potential manufacturing challenges. If successful, this iteration could set a new benchmark for iPhone design and functionality. However, as with any rumored product, final specifications—including display sizes, performance metrics, or even the inclusion of certain features—could still shift before the official announcement.
