Apple may introduce the iPhone 18 lineup in September, but only the Pro models are expected to debut initially. According to the latest information from an industry analyst, the Cupertino-based tech giant could introduce several notable upgrades to the Pro models in the lineup. The handsets, ubiquitously known as the iPhone 18 Pro and iPhone 18 Pro Max, could feature an A20 chip under the hood, while the C2 modem may power networking features.
