In a , smartphone supply chain leaker yeux1122 has shared two new details regarding Apple’s upcoming iPhone 17 Air : its battery capacity and weight.

This account, for the most part, aggregates leaks shared across Chinese social media. It has a somewhat reputable track record when it comes to sharing knowledge from the supply chain.

Todays highlights a few key details regarding the iPhone 17 Air , including the weight, battery capacity, and thickness. These details come from a “mass production confirmed sample.”

It reaffirms that the phone will have a 5.5mm thickness, something that analyst Ming-Chi Kuo has shared in the past . On top of that, it reveals two new specifications:

• A weight of approximately 145g
• Battery capacity of 2800mAh

Recently, we have seen a number of reports surrounding the fact that the iPhone 17 Air will have a less than ideal battery capacity, with Apple’s internal tests finding that only around 60-70% of users will be able to get a full day of battery life out of the phone. Traditionally, that number is around 80-90%.

The battery capacity of 2800mAh isn’t necessarily surprising. That places it around the same battery capacity as the nearly five year old and , both of which shared a 2815mAh cell in a 6.1-inch form factor. Neither of those phones had stellar battery life, but it certainly wasn’t terrible.

Apple is also reportedly implementing an AI-powered battery optimization feature in iOS 19, which’ll likely help the less-than-ideal battery capacity. For reference, iPhone 16 offers a 3561mAh battery, and iPhone 16 Plus offers a 4674mAh battery.

That means iPhone 17 Air will have a roughly 20% battery reduction from a standard iPhone, and roughly 40% from an iPhone of a similar screen size.

The post also mentions that theres a “possibility” of installing a high-density battery with a 2800mAh cell size. It mentions that this will increase the “actual capacity” by 15-20% if implemented. If this part comes to fruition, then iPhone 17 Air could come close to matching standard iPhone battery life.

On the more positive side of things, though – the iPhone 17 Air will come in at around 145 grams according to this leak. That places it around the same weight as an or . Those phones came in at 148 grams and 141 grams, respectively.

You’ll essentially experience tiny iPhone levels of weight, stretched across a much larger 6.6-inch canvas.

The iPhone 17 Air will certainly feel light, and should truly live up to its rumored “Air” naming.
