The original iPhone Air‘s battery was the thing everyone complained about, so the newest leak on its successor goes straight for that sore spot. Weibo tipster Digital Chat Station, who has a decent track record on Apple supply-chain details, says the iPhone Air 2 will carry a cell of 3,500mAh or more. That’s up from 3,149mAh in the current model, an increase of roughly 11%.

It won’t win any battery-size contests against a chunky flagship, but that misses the point of the Air. The whole appeal is how thin it is, and squeezing more capacity into that frame without fattening it up is the harder trick. Apple can lean on the more efficient 2nm A20 Pro chip and slimmer display parts to claw back the space, which is likely how a bigger battery fits without ruining the profile.
The same leak lines up with what’s been circulating for months. A 6.55-inch LTPO OLED panel with a 120Hz refresh rate, and the fix people actually wanted after the single-camera first model, a dual rear setup with a 48MP main sensor paired with an ultrawide. The A20 Pro detail also quietly kills off an earlier rumor that Apple might drop in a cheaper, lower-tier chip to cut costs.
Timing-wise, the Air 2 isn’t a 2026 phone. It’s expected in the first half of 2027 next to the iPhone 18 and the cheaper iPhone 18e, since Apple reportedly never meant to run the Air on a fixed yearly cycle. One more thing worth noting from the same leaker: the Air 2 might end up the only ultra-thin flagship on shelves next year, with rival makers reportedly pulling back on the skinny-phone idea after soft demand.
