Apple released four new iPhones in September 2025, with bigger differences between the latest models than ever before. Instead of the usual split between standard and Pro versions, Apple introduced the new iPhone Air, made the feature differences between models more noticeable, and made each one better suited for a specific type of user. This creates a four-model lineup that goes from the budget-friendly and practical iPhone 17 to the highly capable iPhone 17 Pro Max. Each model has its own trade-offs in terms of size, materials, camera features, and battery life. All phones use Apple’s newest A19 chip, so performance is pretty much the same across the board, but the designs, screen sizes, and camera capabilities are more specialized than ever.
This guide covers all the differences—like size, look, cameras, battery life, and prices—so you can decide which one works best for you. These iPhones are not all the same, and knowing the differences is important if you want to find the best one that fits your needs and budget.
Which One Should You Choose?
Apple’s newest iPhone models are more different from each other than ever before, with clear differences in size, design, and features to match different needs. All four models have the same basic performance, so your decision depends on what’s most important to you, like design, camera options, and cost.
iPhone 17: Ideal for people who want a reliable, all-around iPhone at a budget-friendly price.
iPhone Air: Best for those who prefer the thinnest and lightest iPhone, featuring a new premium look and a medium-sized screen, but may have to make do with less powerful cameras, shorter battery life, slower charging, and weaker speakers.
iPhone 17 Pro: Great for users who want a versatile 48-megapixel telephoto lens and a wide range of advanced camera features and hardware in a more compact form, along with improved microphones and faster USB connectivity.
iPhone 17 Pro Max: Perfect for “pro” users who need all the features of the iPhone 17 Pro, but with the biggest screen, longest battery life, and most storage space available.
The iPhone 17 is a good starting point for most users, with the option to upgrade to the Air for a design-focused choice, the Pro for those who prioritize creating content, and the Pro Max for the ultimate experience with everything in the largest size.
