iPhone Air 2 Could Be as Thin as an Unfolded iPhone Duo

Apple's iPhone Air 2 will be approximately 0.4mm thinner than the current model despite having a higher-capacity battery, claims the account " yeux1122 " on the Korean Naver blog. Apple lists the original iPhone Air at 5.6mm thick, so a 0.4mm reduction would put its successor at approximately 5.2mm, around 7% thinner. Interestingly, that would match the thickness of the new iPhone Duo when unfolded. A previous rumor claimed the iPhone Air 2 will feature a 3,500mAh battery . That's up from the 3,149mAh battery in the current iPhone Air, indicating around an 11% increase in raw capacity. The next-generation device is expected to launch early next year alongside the iPhone 18e and the regular iPhone 18.
