What is the battery capacity of iPhone 17 air?

The battery capacity of the iPhone 17 Air is rumored to be in the range of 2,800 to 2,900 mAh, based on multiple leaks and reports. Specifically:

• A leak from a Korean source claims the iPhone 17 Air has a battery capacity of approximately 2,800 mAh, based on a "mass production confirmed sample."
• Another leaker reported a capacity of around 2,900 mAh for a battery with a metal casing, though there was initial confusion about whether this applied to the iPhone 17 Air or iPhone 17 Pro.
• A Weibo source corroborated that the battery capacity will be below 3,000 mAh, aligning with the 2,800–2,900 mAh range.

This capacity is significantly smaller than other iPhone 17 models (e.g., iPhone 17 Pro Max is rumored at ~5,000 mAh) and the iPhone 16 Plus (4,674 mAh), due to the ultra-thin 5.5mm design of the iPhone 17 Air. There are also mentions of a potential silicon-carbon battery to increase energy density by 15–20%, which could improve effective capacity, but concrete evidence is lacking.

Note: These figures are based on rumors and leaks, as Apple has not officially confirmed the iPhone 17 Air’s battery capacity. The device is expected to launch in September 2025, and final specifications may vary.
