Leak Reveals Ultra-Thin iPhone 17 Air Battery Measuring Just 2.49mm

A new leak from yeux1122 on Naver has sparked major buzz, showcasing what’s claimed to be the iPhone 17 Air’s battery—and it’s unbelievably thin. According to the images, the component measures just 2.49mm in thickness, making it one of the slimmest batteries Apple has ever used in an iPhone.

Key Details From the Leak

• Thickness: 2.49mm (compared to a thicker Pro model battery shown in the same image).

• Previous Leak Corroboration: A May report from the same source suggested a 2800mAh capacity for the Air model, consistent with Apple’s rumored 5.5mm ultra-slim design.

• Material: Metal casing for durability and possibly better heat dissipation.

• Comparison: The standard iPhone 17 Pro battery looks considerably bulkier in the leaked side-by-side shot.

Why It Matters

The iPhone 17 Air is rumored to replace the Plus model and become Apple’s thinnest large-screen iPhone ever. Its ultra-thin design has already been described as “scary thin” in hands-on videos of dummy units. However, this sleek profile comes with trade-offs:

• Smaller battery capacity (~2800mAh) could raise concerns about battery life.

• Apple is reportedly developing a dedicated battery case to mitigate this issue.

Other iPhone 17 Air Highlights

• Horizontal “runway strip” camera layout for the rear design.

• Premium finish options like Light Gold and Light Blue.

• Positioned as an ultra-thin alternative to the Plus model, with a rumored emphasis on style and portability.

Launch Timeline

Apple is expected to unveil the iPhone 17 lineup in Fall 2025, including:

• iPhone 17 Air

• iPhone 17 and iPhone 17 Pro

• iPhone 17 Pro Max (or Ultra)
