Apple has unveiled the battery design for its upcoming iPhone 17 Air, featuring a compact and refined steel case. The estimated capacity of 2,900 mAh is aimed at achieving a slimmer profile while balancing lightness and functionality.
The use of steel in the battery case enhances heat dissipation, structural resistance, and integration with the phone’s logic board. This technology was first introduced on the iPhone 16 Pro and has been implemented seamlessly into the new design.
The battery module boasts a precise finish, with carefully welded edges. The new battery adhesives will make replacement easier, as noted in previous reports.
While no official charging speed data is available, the steel case and reduced capacity suggest an advanced thermal management system that could support higher charging powers. Apple has already initiated this approach on the iPhone 16 Pro.
These images provide insight into the development path of the iPhone 17 Air, which is expected to launch in September 2025. The use of a steel case reinforces Apple’s technical direction and suggests a promising new battery design for the upcoming phone.
