According to a new leak from Naver user yeux1122, Apple’s upcoming iPhone 17 Air may fall short in battery life. The device will feature a 2800mAh battery. That’s roughly 20% smaller than the standard iPhone battery and about 40% smaller than the iPhone 16 Plus. Internal tests reportedly show that only 60 to 70 percent of users will make it through a full day on a single charge, well below the usual 80 to 90 percent.
Key Specs from the Leak
- Battery capacity: 2800mAh
- Weight: Approximately 145 grams
- Thickness: 5.5mm
- Display size: 6.6 inches
- Reported battery endurance: 60 to 70 percent of users will get a full day
- Potential improvement: High-density battery version may increase capacity by 15 to 20 percent
Smaller Battery, Larger Concerns
The 2800mAh battery mirrors the capacity of the iPhone 12 series, which also wasn’t known for long-lasting performance. With the iPhone 17 Air sporting a larger 6.6-inch display, concerns around endurance are justified. Apple plans to introduce an AI-powered battery optimization feature in iOS 19, which could partially offset the smaller cell. However, battery performance is expected to lag behind current models unless Apple integrates the rumored high-density battery, offering up to 20 percent more effective capacity.
Light Weight, But at What Cost?
The iPhone 17 Air is expected to weigh around 145 grams, similar to the smaller iPhone SE 2 and iPhone 13 mini. The lightweight design pairs with a thickness of just 5.5mm, reaffirmed by the same leak. While this makes the phone impressively slim and light, it also explains the reduced battery size.
As reported by yeux1122 on Naver, these details are based on a mass production confirmed sample from Apple’s supply chain. If accurate, users will need to weigh the trade-off between a sleek design and daily battery reliability.
