Whether you’re due for an upgrade or just curious what’s changed, there’s a lot to unpack this year. From Pro-level features coming to the standard iPhone to new tricks for creators and better battery life across the board, this is one of Apple’s most balanced lineups yet.
In a hurry? Skip ahead to A Quick Look for the 10 must-know highlights.
iPhone 17 Series Overview
Apple’s 2025 iPhone lineup is bigger, brighter, and a lot more streamlined. There are four models this year: the baseline iPhone 17, the latest iPhone Air, and the coveted iPhone 17 Pro and iPhone 17 Pro Max.
The iPhone 17 is the crowd-pleaser. It’s a little bigger at 6.3 inches, packs sharper cameras, and now has the same buttery-smooth 120Hz ProMotion display as the Pro models.
The all-new iPhone Air is the thinnest iPhone ever (just 5.6mm!) but still manages to squeeze in a 6.5-inch display and a titanium frame that keeps it sturdy. You can think of it as the spiritual successor to the Plus, but slimmer, lighter, and a little more premium.
If you want it all, the iPhone 17 Pro and Pro Max are where the tech giant puts its best tech. Shedding the previous titanium build, you get a new aluminum unibody design with vapor chamber cooling, triple 48MP cameras with up to 8x zoom, and the most powerful A19 Pro chip. The Pro Max stretches that experience across a massive 6.9-inch display and packs Apple’s highest-capacity battery to date.
All four phones now start at 256GB of storage (a twofold bump over the iPhone 16), share brighter 3,000-nit displays, and ship with iOS 26 preinstalled. No matter which one you pick, you’re getting a faster, more capable iPhone that’s built to last.
Each model also gets its own personality through color. The iPhone 17 comes in softer tones like Lavender, Sage, and Mist Blue in addition to standard White and Black; while the Air sticks to a more minimal palette with Space Black, Cloud White, Light Gold, and Sky Blue. The Pro and Pro Max go bolder, with the bright Cosmic Orange standing out against Deep Blue and Silver.
Feature Rundown
Design and Display
The iPhone 17 range marks Apple’s most dramatic visual shift in years. The standard iPhone 17 grows to a 6.3-inch display with slimmer bezels; and the Air, Pro, and Pro Max, now feature a striking full-width camera plateau. The super-thin iPhone Air steals the spotlight at just 5.6mm, making it the thinnest iPhone ever, while still packing a large 6.5-inch OLED panel. The Pro and Pro Max models switch from titanium to a forged aluminum unibody that not only cuts weight but also improves heat dissipation for better sustained performance.
Every model now supports ProMotion with up to 120Hz adaptive refresh rates, Always-On display, and up to 3,000 nits of peak outdoor brightness. Ceramic Shield 2 protects the glass with three times better scratch resistance, and a new anti-reflective coating reduces glare in sunlight. Apple even highlights a minimum brightness of 1 nit for comfortable night viewing, which brings parity between standard and Pro displays for the first time.
Camera and Multimedia
This year’s camera system is a major leap forward. Every iPhone 17 model features an upgraded 18MP front-facing camera with a square sensor that allows portrait or landscape selfies without rotating the phone. Center Stage can now automatically zoom, pan, and even flip orientation based on how many people are in the frame. Dual Capture finally arrives as a native feature, letting you record simultaneously with the front and rear cameras in up to 4K.
On the back, the iPhone 17 now gains dual 48MP cameras: a Fusion Main camera with 2x optical-quality telephoto and a Fusion Ultra Wide camera with 4x the resolution of the iPhone 16’s Ultra Wide. Ultra Wide photos default to 24MP for a balance of detail and file size. The Pro and Pro Max models go all-in with triple 48MP cameras, including the longest telephoto ever on an iPhone with up to 8x optical-quality zoom (200mm equivalent). Digital zoom stretches to 40x, and pro video tools like ProRes RAW, Apple Log 2, Genlock, and Dolby Vision 4K at 120fps make these models a powerhouse for creators.
The iPhone Air is the outlier, offering just a single 48MP Fusion camera with 1x and 2x zoom and no Ultra Wide. Reviewers note this makes it less flexible for photography enthusiasts despite its premium price.
Performance and Battery
Under the hood, the iPhone 17 runs on the new A19 chip built on Apple’s third-gen 3-nanometer process, while the Air, Pro, and Pro Max use the A19 Pro with an extra GPU core and improved efficiency. Pro models also gain a vapor chamber cooling system filled with deionized water, laser-welded into the chassis for 40% better sustained performance.
Battery life sees a significant boost across the board: 30 hours of video playback on iPhone 17, 33 on the Pro, and 39 on the Pro Max — the longest ever on an iPhone. The Air still manages a respectable 27 hours despite its ultra-thin design. Charging is faster too, with the iPhone 17, Pro, and Pro Max reaching 50% in about 20 minutes with the new 40W Dynamic Power Adapter. The Air takes roughly 30 minutes to hit the same mark, not too far behind.
Software and iOS Features
All models ship with iOS 26 and the new Liquid Glass interface that adds a modern, transparent aesthetic to menus, notifications, and the lock screen. Apple Intelligence, the company’s on-device AI framework, is present but brings no new flagship features this year, instead building on tools introduced with iOS 17. The real leap for Apple Intelligence is expected next spring, with deeper features possibly powered by both Apple technology and partners.
Security also gets a boost with Memory Integrity Enforcement, a behind-the-scenes feature that protects against memory corruption exploits frequently used in high-end spyware attacks. On the Pro models, users sensitive to OLED flicker will appreciate a new setting that lets them disable PWM dimming, reducing headaches and eye strain.
Connectivity and Extra Features
Every iPhone 17 model supports Wi-Fi 7, Bluetooth 6, 5G, Thread networking, eSIM, and IP68 water resistance. The iPhone Air is the only model with Apple’s new C1X modem, delivering up to twice the speed of the original C1. USB-C is standard across the range, but only the Pro models support USB 3 speeds up to 10Gbps; the iPhone 17 and Air remain limited to USB 2 at 480Mbps.
