According to the latest supply chain rumors, Apple is developing a second-generation iPhone Air slated for spring 2027. The main upgrade centers on battery life. Serial leaker Digital Chat Station posted on Weibo that the iPhone Air 2 will likely pack a 3,500mAh battery, an 11% increase over the current model's 3,149mAh. A larger capacity does not automatically mean a bigger device; Apple could improve internal packaging to fit a larger cell in the same chassis, much like previous designs.
3,500mAh Battery and Thinner Display Technology
The capacity boost could come from a physically bigger battery or higher energy density. Reports also suggest Apple will adopt Samsung's CoE (Color Filter on Encapsulation) OLED technology, which makes the display thinner. This saved space may allow for a slightly larger battery without altering external dimensions. The upcoming A20 chip, built on Apple's 2nm process, will bring better energy efficiency, further extending battery life. The tight internal layout mirrors the original iPhone Air, where multiple components are housed in the plateau to maximize battery space.

Ultra Wide Camera to Address Key Complaints
A major criticism of the current iPhone Air is its single rear Wide lens. Apple is expected to add an Ultra Wide camera to the iPhone Air 2, giving users a dual-lens system comparable to the cheaper iPhone 17. However, integrating a second sensor will require significant internal redesign, potentially affecting battery placement. The leaker did not clarify if the battery capacity remains unchanged with the added camera, but optimization efforts may compensate.

A20 2nm Chip and Slimmer OLED Panel
Beyond the battery, the iPhone Air 2 will feature the A20 chip built on Apple's 2nm process, a generational leap in performance and efficiency. This chip will contribute to better battery life regardless of capacity changes. Meanwhile, the CoE OLED display will reduce thickness, allowing Apple to add the camera without increasing the phone's footprint. These technical innovations promise an even slimmer and more powerful device.
Launch Expected in First Half of 2027
The iPhone Air 2 is expected to launch alongside the iPhone 18 and the lower-cost iPhone 18e in the first half of 2027. This lineup suggests Apple is targeting a diverse portfolio, with the Air positioned as a slim premium model now boasting improved battery and a second camera. The semiconductor industry is booming, as evidenced by South Korea's chip workers becoming highly sought-after singles thanks to AI bonuses (read our article on South Korea's chip workers). Apple itself relies on this supply chain for its custom processors, and the 2nm A20 chip marks another milestone. For a history of iPhone, visit the Wikipedia page.
