Apple is rumored to be planning major design changes for the upcoming iPhone, particularly on the iPhone 20 model expected to launch in 2027 to celebrate the 20th anniversary of the iPhone. The iPhone 20 is predicted to have a thinner frame like the iPhone Air, curved glass on the front and back, and solid-state touch buttons replacing physical buttons. Significant changes will also occur in the cooling system, with the use of a larger vapor chamber for improved heat dissipation efficiency. Leaks regarding the specifications of the iPhone 20 Pro Max mention a 6.96-inch screen and a 6,000 mAh battery.
