Highlights

• New leak confirms the iPhone 17 Air will be just 5.5mm thick and weigh around 145 grams.
• It also reveals that the phone might get only 2800mAh battery with only 60–70% of users expected to get a full day’s use.
• Apple may use a high-density battery and iOS 19’s AI-based optimisation to increase battery capacity by 15–20%.

We already have a fair idea of what Apple is planning with its upcoming iPhone 17 Air model. But since it is Apple we are talking about, it is not surprising that every day some new detail comes into light. A new leak has now revealed more details about Apple’s upcoming iPhone 17 Air and it’s a bit of a mixed bag.

The info comes from leaker yeux1122 via a post on Naver, who cites a “mass production confirmed sample” from the supply chain.

According to the post, the iPhone 17 Air will be just 5.5mm thick, a spec that lines up with earlier reports from analyst Ming-Chi Kuo. On top of that, the new leak reveals the phone will weigh around 145 grams. That makes it as light as the iPhone SE 2 (148g) or iPhone 13 mini (141g) but stretched out over a much larger 6.6-inch display. So you’re getting the feel of a mini iPhone, but in a full-sized body. That alone could justify the “Air” branding.

While the weight is impressive, the second part of the leak doesn’t sound too pleasing.

It appears we are getting battery capacity of just 2800mAh, which might rightly be a concern. Internal testing by Apple reportedly shows that only 60–70% of users will get a full day of use, compared to the usual 80–90% on typical iPhones.

To put that into context, the iPhone 12 and 12 Pro, both released in 2020, had nearly the same battery capacity (2815mAh) and were not exactly known for long-lasting battery life either. Meanwhile, the iPhone 16 features a 3561mAh battery, and the iPhone 16 Plus has a massive 4674mAh cell. So compared to those, the iPhone 17 Air sees about a 20% drop from standard models and up to 40% less compared to a similarly sized Plus variant.

There’s a possibility Apple might include a high-density battery using the same 2800mAh cell size, which could boost the actual capacity by 15–20%. If that happens, battery life might not be as bad as it sounds.

To add on, iOS 19 is expected to bring an AI-based battery optimisation feature, which should help squeeze out more life from the smaller battery.
