Apple’s iPhone 18 Pro Max: Maintaining Slimness Amidst Anticipated Upgrades
Recent leaks suggest that Apple’s forthcoming iPhone 18 Pro Max will maintain the same thickness as its predecessor, the iPhone 17 Pro Max, measuring 8.75mm. This information, shared by the Weibo-based leaker Ice Universe, indicates that despite earlier reports predicting a thicker and heavier design, Apple has opted to retain the current profile.

This decision aligns with Apple’s focus on developing its rumored foldable iPhone, potentially named the iPhone Ultra. By concentrating resources on this innovative device, Apple appears to be limiting significant design changes in the Pro lineup for this cycle.

Potential Weight Increase
While the thickness remains unchanged, the iPhone 18 Pro Max may experience a slight weight increase. Earlier claims suggested the device could weigh over 240 grams, potentially making it the heaviest iPhone to date. This increase could result from internal hardware upgrades, such as a larger battery or enhanced components.

Battery Enhancements
Reports indicate that the iPhone 18 Pro Max will feature a battery capacity between 5,100mAh and 5,200mAh, a modest increase from the 5,088mAh battery in the iPhone 17 Pro Max. Apple may achieve this enhancement by redesigning internal components to accommodate the larger battery without altering the device’s thickness.
