Apple is expected to introduce the iPhone 17 Air - the super-thinest and lightest version in the iPhone 17 series - next fall, but a notable weakness has been revealed: unimpressive battery capacity, significantly lower than other versions.
Accordingly, the iPhone 17 Air battery may not exceed 3,000 mAh.
The design of the iPhone 17 Air has an ultra-thin feel of only about 5.5 mm and weighs 145 g, following the "Air" trend like on MacBook Air.
Apple puts design and convenience first, but in return, the battery space must be narrowed.
Apple is expected to adopt advanced silicon-carbon battery technology, which will increase the storage density to 15 20% without increasing physical size; at the same time, iOS 26 will integrate Adaptive Power mode - self-adjusting consumption to extend usage time.
With the iPhone 17 Pro and Pro Max, both are expected to be equipped with batteries with a capacity of 3,500-4.600 mAh, enough to be used comfortably throughout the day, as well as supporting higher-power fast charging, better heat output and greater RAM capacity - serving heavy processing needs such as 8K video recording or gaming.
Meanwhile, the iPhone 17 Air, despite its lightweight design, does not support high-power fast charging, does not have a telephoto camera and the versatility is also limited.
