8.75mm is the thickness now tipped for Apple’s iPhone 18 Pro Max, matching the iPhone 17 Pro Max despite earlier claims it would grow thicker.
5,100 to 5,200 mAh battery rumors help explain the surprise, suggesting Apple may be reworking internal components to fit a larger cell without changing the chassis.
240 grams is still a reported possibility, with separate leaks saying the phone could become Apple’s heaviest iPhone since the iPhone 14 Pro Max even if thickness stays flat.
6.9 inches remains the expected display size, while other rumored upgrades include a smaller Dynamic Island, C2 modem, simplified Camera Control and a variable-aperture main camera.
Mid-September is the expected launch window, with leaker chatter also pointing to Apple prioritizing development of a foldable 'iPhone Ultra' alongside the Pro lineup.
