A few days ago, a rumor doubled down on some previously leaked claims about the iPhone 18 Pro being noticeably thicker than its predecessor, by about 2mm.
Today, prolific leaker Ice Universe has revealed the iPhone 18 Pro Max’s weight and thickness, and if these numbers are accurate, it could be noticeably chunkier than last year’s model. According to the leak, it will weigh 240g and be 9mm thick.

For comparison, the iPhone 17 Pro Max weighs 233g and is 8.8mm thick, so the increase is not actually as large as previously rumored. If last year’s model feels fine to you, the upcoming one will too.
To put things in perspective, the upcoming Samsung Galaxy Z Fold8 is rumored to weigh about 201g — and that’s a folding smartphone. The iPhone 18 Pro Max’s added weight is likely linked to its increased battery capacity, which is generally a welcome improvement in a new phone launch.
A recent certification revealed that it will pack a 5,567 mAh battery in the eSIM-only version, while the model retaining a physical SIM card will have a 5,391 mAh cell. The iPhone 17 Pro Max’s numbers are 5,088 mAh and 4,823 mAh, respectively.
