As Apple prepares for the anticipated iPhone 17 Air release later this year, new leaks are shedding light on two crucial specs: battery capacity and device weight. While most previous rumors have focused on the design and thin form factor, fresh information now gives us a better idea of what to expect under the hood.
iPhone 17 Air Battery Capacity: 2,800 mAh or More?
According to the leaker “yeux1122” via a post on Korea’s Naver blog, the iPhone 17 Air will pack a 2,800mAh battery. The source claims this data comes from a mass production-confirmed sample, giving the rumor added credibility.
However, Apple may use a next-gen high-density battery, which could increase the effective capacity by 15–20%. Apple analyst Ming-Chi Kuo had previously mentioned this upgraded battery technology, and reports now suggest that TDK, an Apple supplier, is preparing to ship silicon-anode batteries by the end of June.
Weight: Ultra-Light at 145 Grams
Weighing in at just 145 grams, the iPhone 17 Air is expected to feel significantly lighter than most modern iPhones. That’s roughly in line with the iPhone SE 2 (148g) and iPhone 13 mini (141g), making it a compelling option for users who prefer ultra-light devices.
Battery Life Concerns Spark Mixed Reactions
Battery performance is shaping up to be a point of contention. A report from The Information claims that only 60–70% of users may experience all-day battery life, compared to 80–90% for other iPhone models. In response, Apple is reportedly planning to launch a battery case accessory to mitigate concerns.
On the flip side, Bloomberg’s Mark Gurman provides a more hopeful view, suggesting that hardware and software optimizations will result in battery life on par with current iPhones.
iPhone 17 Air: Slim Build, No Ultra-Wide Camera
The iPhone 17 Air is expected to be just 5.5mm thin, making it the slimmest iPhone ever. The device may lack an ultra-wide camera, a trade-off that could free up internal space for battery improvements. Additionally, Apple’s power-efficient C1 modem is expected to contribute to longer battery endurance.
The iPhone 17 Air is set to replace the “Plus” model in Apple’s iPhone lineup and is expected to launch in mid-September 2025, following Apple’s traditional fall event cycle.
The iPhone 17 Air is shaping up to be a bold new addition to Apple’s smartphone portfolio—ultra-light, ultra-thin, and possibly equipped with high-efficiency battery tech. While concerns about battery longevity persist, Apple may have tricks up its sleeve with hardware improvements and optional accessories. Stay tuned as more details emerge closer to launch.
