Leak: iPhone 18 Pro Max to Weigh 243 Grams, Heaviest iPhone

A new leak suggests that Apple's upcoming iPhone 18 Pro Max could become the heaviest iPhone the company has ever produced, weighing around 243 grams and measuring slightly thicker than its predecessor. The device is slated for release in the fall of 2026, according to Instant Digital, a Weibo-based leaker with a mixed but occasionally accurate track record on Apple rumors.

The reported weight would mark a 10-gram increase over the iPhone 17 Pro Max, which weighs 233 grams. This would surpass the previous record held by the iPhone 14 Pro Max at 240 grams. Instant Digital also indicated that the iPhone 18 Pro Max would retain its 6.9-inch display but feature a marginally thicker chassis, potentially exceeding the 8.8-millimeter depth of the iPhone 17 Pro Max. For context, earlier models like the iPhone 15 Pro Max and iPhone 16 Pro Max were lighter at 221 grams and 227 grams, respectively, thanks to titanium frames, while the iPhone 17 series reverted to aluminum construction, contributing to added heft.

Several hardware upgrades are rumored to explain the increase. Analysts point to a possible larger battery, which has been a focus in recent iPhone designs to extend usage time....
