According to a new rumor, the iPhone Air 2, expected to launch next spring alongside the iPhone 18 and iPhone 18e, will be even thinner than its predecessor. How thin? 5.2mm. That's 0.4mm less than the original iPhone Air from 2025. Obviously it's a tiny difference, but you can't really expect much since the iPhone Air was already very thin.
The source of this leak also says that the iPhone Air 2's battery life will be improved compared to its predecessor, hinting that a high-density battery will be used in it, in a similar fashion to the iPhone 18 Pro and iPhone 18 Pro Max. So we should expect an increase in capacity, though not a huge one.
That confirms previous rumors, and this is clearly something that Apple needs to address since battery life is one of the most common complaints about the iPhone Air (along with the fact that it only has one rear camera). Anyway, the iPhone Air 2 is also said to retain the titanium frame that was introduced in the original iPhone Air.
