The upcoming iPhone 20, set to celebrate Apple's 20th anniversary of the iPhone, is rumored to come in two different screen sizes, marking a significant shift in Apple's design language. This development, according to Bloomberg's Mark Gurman, will replace the iPhone 18 Pro and iPhone 18 Pro Max, offering similar screen sizes of 6.3-inch and 6.9-inch displays. This move away from the iPhone 19 Pro suggests Apple is aiming for a more unified approach to its product lineup. The iPhone 20 is expected to feature a unique design with an uninterrupted curved glass display, hiding the metal frame and creating an all-glass illusion. Rumors also suggest the phone may ditch the cutout for the front camera and Face ID, in favor of under-display options, and include solid-state buttons with haptic feedback, a stronger version of Ceramic Shield, and a 6,000 mAh battery. The iPhone 20 will run on a new 2 nanometer A21 chip, code-named Naxos, which will also power the second-generation Apple foldable, codenamed V78. This suggests Apple is planning on updating its foldable phones annually. The iPhone 20's design and features are set to be a significant upgrade, marking a new era for Apple's flagship devices. However, the lack of information about the iPhone Ultra 2 and the ongoing speculation around the iPhone Fold 3 indicate that Apple is carefully managing its product roadmap, keeping details under wraps until the last minute.
