Apple is set to unveil the iPhone 18 Pro models on Wednesday, September 9, featuring design elements largely similar to the iPhone 17 Pro with internal enhancements. Major design changes are not expected until 2027, when Apple plans a radically redesigned 20th-anniversary model. For those considering an upgrade this year, several rumored features for the 2027 models may justify waiting.

Apple is reportedly developing a quad-curved, all-glass design for the iPhone 20, with display glass curving away on all four sides to conceal the metal frame for a borderless effect. The company is also planning to use brighter, thinner OLED panels with Samsung's Color Filter on Encapsulation technology to improve light throughput. Further rumors suggest Apple is testing under-display Face ID and camera technology to eliminate the Dynamic Island, though readiness for a fall 2027 launch remains uncertain.

Other anticipated upgrades include a custom stacked Apple image sensor using LOFIC technology for improved dynamic range, haptic solid-state buttons integrated into the frame, and a second-generation 2-nanometer A21 Pro chip. Additionally, Apple is exploring silicon anode battery technology and vertically stacked DRAM to enhance performance and longevity.
