We’re supremely confident that Apple’s September 2023 event will play host to the launch of the iPhone 15 series, with four new mobile devices ready and waiting to shake up our ranking of the best iPhones money can buy.

Specifically, we’re expecting an iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max to arrive alongside a customary standard model this year. And you’ll find detailed specs, features, pricing and availability information for all four phones in our product-specific rumor hubs.

In this article, though, we’ve collated the rumored key upgrades for the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max in bullet point form. Below, you’ll find a simple breakdown of (what are expected to be) each phone’s biggest selling points, along with a comparative table of rumored specs, so you can compare Apple's upcoming models at a glance.

Model comparison

Here’s how we expect the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max to compare on the specs front. The below information remains speculative for now, but it’s nonetheless based on consistent leaks, rumors and predictions from industry insiders.
