NEW YORK, July 19: Apple is expected to launch the ultra-thin iPhone 17 Air this fall, introducing a radically slim design to its flagship lineup. However, new reports suggest that the sleek form factor may come at a cost — particularly when it comes to battery capacity.

According to recent leaks, the iPhone 17 Air will feature a battery capacity that does not exceed 3,000mAh. One leaker, known as yeux1122, initially claimed in May that the device would be equipped with a 2,800mAh battery. That estimate now appears to be supported by a new post on Weibo from the leaker Instant Digital, who reiterated that the battery will remain under the 3,000mAh mark.

If accurate, the iPhone 17 Air’s battery would fall significantly below that of its counterparts in the iPhone 17 series. The iPhone 17 Pro Max, for example, is rumored to include a 5,000mAh battery. Even last year’s iPhone 16 and iPhone 16 Pro offered capacities around 3,500mAh.

Compounding concerns is the iPhone 17 Air’s larger display, which could demand more power compared to previous base models. By comparison, the iPhone 16 Plus featured a 4,674mAh battery, offering a benchmark for what larger-screen devices can deliver in terms of endurance.

Despite these limitations, Apple appears to be taking steps to address potential battery life concerns. The upcoming iOS 26 will reportedly include a new Adaptive Power Mode, designed to optimize energy consumption. In addition, Apple is said to be developing a new battery case accessory to extend usage time for power users.

Still, for many consumers, battery life may be a deciding factor — especially as competitors continue to offer larger capacities in similarly sized devices.

The iPhone 17 Air is poised to appeal to users who prioritize portability and design. However, whether its reduced battery capacity becomes a dealbreaker remains to be seen.
