Apple’s upcoming iPhone 18 Pro Max will be the same thickness as its predecessor, measuring 8.75mm. The latest information comes from Weibo-based leaker Ice Universe.
The leaker suggested that the lack of evolution in Apple’s Pro lineup this year is because most of the company’s development has been focused on the “iPhone Ultra,” its rumored foldable model.
The latest claim is somewhat surprising, given that the same leaker said in March that the device would be slightly thicker than the iPhone 17 Pro Max. This echoes a report from last year alleging that hardware changes to the iPhone 18 Pro Max would make it the heaviest iPhone yet.
Last November, Instant Digital, another Weibo-based leaker, said the iPhone 18 Pro Max would be slightly heavier than its predecessor, tipping its weight above 240 grams and making it the heaviest iPhone since the iPhone 14 Pro Max.
Of course, if the new model turns out to be the same thickness, that doesn’t necessarily mean its weight won’t change either. The heaviness of the device could still be affected by internal hardware modifications.
Digital Chat Station – another Weibo-based leaker – has claimed that the iPhone 18 Pro Max will feature a bigger battery, with a capacity between 5,100 and 5,200 mAh (compared to 5,088 mAh in the eSim version of the iPhone 17 Pro Max).
If so, Apple may have reconfigured the internal design or miniaturized aspects of it in order to accommodate a larger battery without altering the thickness of the device. Apple is not expected to change the screen size of the iPhone 18 Pro Max, and it will feature the same 6.9-inch display as the current model.
The ‌‌iPhone 18‌‌ Pro and iPhone 18‌‌ Pro Max may feature a possibly smaller dynamic island, as well as a next-generation C2 modem, simplified camera control, and an improved main camera with variable aperture. The devices are expected to be revealed around mid-September alongside the foldable iPhone.
