Kerry Wan/ZDNETApple is planning a major iPhone launch timeline refresh. For years, the company has launched the base iPhone with its Pro variants, but it could change starting in 2027. Both The Information and Kuo have predicted a staggered rollout for the iPhone 18 series. A few models in the lineup are said to launch in the usual September window, while others might be announced in March the following year.

Historically, Apple has reserved the March to April window for the launch of more affordable iPhones like the iPhone SE series and iPhone 16e. However, this timeline could receive a refresh as the Apple iPhone lineup expands with new models. For context, Apple is rumored to launch a new iPhone 17 Slim later this year. It is said to replace the Plus series, which was a replacement for the Mini lineup.
