TheiPhone 17 Airis rumored to be Apple’s slimmest iPhone yet, while a new leak suggests that theiPhone 17 Pro Maxmight be one of the thickest.

According to known tipsterIce Universeon X, the iPhone 17 Pro Max is expected to be 8.725mm thick, surpassing the iPhone 16 Pro Max’s thickness of 8.25mm. This would make it the thickest iPhone in well over a decade, coming shy of theiPhone 4s, which measured 9.3mm thick.

Why is Apple possibly increasing the thickness? Reports indicate it could be because it is planning to put a larger battery in the device (via9to5Mac). However, a bigger battery doesn’t automatically equate to longer battery life, particularly if Apple is developing more power-intensive features withApple Intelligence.

Of course, the iPhone 17 Air’s slimness will come with compromises, likely in terms of battery life and its cameras. On the other hand, the increased thickness of the iPhone 17 Pro Max could also be attributed to its cameras. Apple is reportedly working on improving itsvideo capturecapabilities, and it’s rumored the phone could have a sizablerectangular camera bar. This year’s iPhone launch sure sounds like it’s shaping up to be one of the most interesting in years.
