The 20th‑anniversary iPhone, slated for late 2027, is rumored to adopt a glass‑heavy design reminiscent of the iPhone Air. Fixed Focus Digital’s Weibo post claims the new model will be chiefly made from glass, echoing long‑standing speculation. The mid‑frame will mirror the Air’s thin profile, and the device will feature an enlarged heat‑dissipation plate, reportedly one inch larger than current models. This suggests Apple may enhance thermal management, possibly adding vapor‑circuit cooling or simply increasing material to better disperse heat. While the Air lacks vapor‑circuit cooling, the 17 Pro line’s system already showcases efficient heat transport. Analysts note that if Apple integrates vapor‑circuit plates into the anniversary phone, the larger cooling area could make the slim design more viable. Fixed Focus Digital’s track record is mixed; they correctly predicted the iPhone 16e name but have made inaccurate claims before. Nonetheless, the rumor score remains likely, and Apple’s rumored glass‑centric aesthetic and improved cooling point to a refined, yet still ultra‑thin, 20th‑anniversary essentials困难

Industry observers anticipate the glass-heavy build could also reduce weight, improving handling, while the advanced cooling might allow higher refresh rates and sustained performance under heavy use. The design hints that Apple will celebrate two decades while pushing forward.
