Which iPhone 17 Model Should You Buy?

Apple’s 2025 iPhones are here, and things are quite different for the first time in a while. The base iPhone 17 will still feel familiar, but the iPhone 17 Pro models have a completely new look, and there's a brand-new model called the iPhone Air. The “Air” branding has been somewhat diluted of late—the current-gen iPad Pro models are lighter than the iPad Air—but the iPhone Air brings meaning back to the original idea: a super-thin and ultra-lightweight device.

Preorders kick off September 12, and official sales start September 19. If you're considering an upgrade, what model should you get? I'll break down the key differences and similarities among the iPhone 17 lineup, so you can hopefully make a more informed choice on your next iPhone.

If you have an iPhone from just a few years ago, you probably don't need to upgrade to Apple's latest, unless your device has issues. Even then, there are things you can do to fix your iPhone, like getting a battery replacement, or you can try some of these troubleshooting steps. The point is, you shouldn't feel the need to upgrade just because Apple has a new model.

If you're set on buying an iPhone 17 model, we have a guide on how to sell your iPhone so that it doesn't just collect dust in a drawer. When your new device arrives, back up your old iPhone before switching to the new one, then follow our guide on factory resetting your device before selling or giving it away. We also have tips on how to set up your new iPhone and what settings to change to get the most out of it.

Let's quickly talk about the similarities across all the iPhone 17 models this year, and yes, that includes the iPhone Air, even if it doesn't have “17” in the name.

Although iPhones differ in screen size, they all feature an OLED screen (Apple refers to it as a Super Retina XDR display) and employ ProMotion technology. This is the first time the non-Pro models have ProMotion, which is essentially a 120-Hz refresh rate.

This has been a common feature on Android phones for a while, but it means your display refreshes 120 times per second rather than 60, like on the iPhone 16, so everything you do will feel smoother. (We have a broader explainer here.) These are adaptive refresh rates that can drop as low as 1 Hz when there's little activity on the screen, which is why the new iPhone 17 and iPhone Air now support the always-on display.

Apple also says there's a new Ceramic Shield 2 front glass that's 3X more scratch-resistant than before, and a new antireflective coating to reduce glare. All of these screens can also hit up to 3,000 nits of peak brightness, meaning it'll be easier to read your iPhone screen on sunny days.

The front-facing selfie camera is identical on all the iPhone 17 models. It's a new square-shaped 18-megapixel sensor, and that means you can expect more detail out of your selfies. However, the square sensor also introduces a smarter way to capture group selfies. You can keep holding your phone in portrait orientation for the best grip, and it will automatically zoom out to make sure everyone fits in the frame, while also switching to a landscape orientation for the widest view. All of these models also support Dual Capture, which lets you shoot with both the front and rear cameras at the same time. You can read more about these features here.

All of the iPhones are IP68 water- and dust-resistant and have Face ID, the Camera Control button, Action Button, USB-C, and Qi2 magnetic wireless charging (MagSafe). All devices start at 256 GB of storage. There's Apple Intelligence on these devices, the same Emergency SOS via Satellite and Crash Detection capabilities, and they utilize Apple's new N1 wireless networking chip for Bluetooth 6, Wi-Fi 7, and Thread support.

Now, here's where they diverge, which will help you better understand what model to buy.

As usual, the 6.3-inch iPhone 17 will most likely be the best iPhone for most people. The screen is slightly larger than its predecessor, there's more storage, and it finally features Apple's ProMotion 120-Hz technology. It's the only iPhone in the new lineup with the base A19 chipset, so while you should be able to run almost every app and game with ease, the next few iPhones in this list will deliver better performance, particularly with graphics-heavy apps.

While the iPhone 17 has the new Ceramic Shield 2 glass on the front to protect the screen, it doesn't use the original Ceramic Shield on the back glass; that's exclusive to the Air and Pro models. The 48-MP main camera may sound similar to the others, but it's not going to deliver the best results, though the ultrawide camera has been upgraded to 48 megapixels and should match the quality of the Pro iPhones.

The iPhone Air is the most unusual of the bunch. It's shockingly thin and lightweight, merely 5.6 mm and 165 grams. It's the only iPhone in the new series made from titanium, to ensure the thin frame remains durable. (Remember Bendgate?) The back also features the original version of Ceramic Shield, which gives it a slight boost in durability over the iPhone 17. It also has a unique 6.5-inch screen size.

With this new thin design, there are compromises to the camera. You only get a single 48-MP camera, the same as on the iPhone 17, but no ultrawide or telephoto. It lacks Cinematic mode for video and spatial video recording, both of which are available on the iPhone 17 and iPhone 17 Pro. The iPhone Air does enjoy a slight bump in performance with the A19 Pro chipset versus the A19 in the iPhone 17, though we'll have to wait to see if it's a minimal one or not.

The Air has the worst battery life according to Apple's claims compared to the rest of the new iPhones, but it still supposedly matches the iPhone 16 Plus from 2024, so we'll have to wait and see how it fares. Like the iPhone 17, the USB-C still only supports USB 2 data transfer speeds, meaning you're limited to 480 Mbps. It charges more slowly, hitting 50 percent in 30 minutes, whereas the iPhone 17 can do that in 20 minutes (with the right charging adapter). Even wirelessly, it only supports 20-watt Qi2 charging instead of 25 watts.

This is the only iPhone with Apple's new C1X modem. It's very efficient, but it means this iPhone doesn't support millimeter wave 5G, just sub-6 5G. (Read our 5G explainer to learn the differences.) That may not be a big deal since you only encounter that faster 5G in high-traffic areas, airports, and stadiums, but it's something to keep in mind.

The iPhone 17 Pro retains its 6.3-inch display but now has an aluminum unibody instead of titanium, supposedly for improved heat dissipation. Like the iPhone Air, it also employs Ceramic Shield on the back glass, in addition to Ceramic Shield 2 on the front.

Speaking of heat, these are the first iPhones with a vapor chamber cooling system. This is a heat dissipation technology we've seen on Android phones for years, but there's a single drop of water inside the iPhone that moves through the chamber from vapor to liquid to keep the iPhone cooler for longer, and disperses heat better. That should deliver better sustained performance, and so should the A19 Pro. Unlike the A19 Pro on the Air, it has one extra graphics core here.

The telephoto camera has been upgraded to 48 megapixels, so now you have an entire triple-camera array with 48-MP sensors. It delivers 4X optical zoom and up to 8X optical-like quality. It's still the only iPhone model that can shoot 4K at up to 120 frames per second, and there are numerous exclusive video features aspiring filmmakers may find useful, like Genlock and ProRes RAW. It has better image stabilization than the other models, a better flash, and nicer microphones, and Apple still only offers the Lidar scanner on these Pro models.

The iPhone 17 Pro Max is identical to the iPhone 17 Pro except in size. It sports a 6.9-inch screen, making it the heaviest iPhone, but it also has the biggest battery, boasting up to 39 hours of video playback compared to 33 hours on the iPhone 17 Pro. It's also the only iPhone with a 2-terabyte storage option, if you need that much local space.

Like the smaller Pro, the USB-C supports USB 3, so you can take advantage of up to 10 Gbps data transfer speeds, a big boost over the iPhone Air and iPhone 17.

• iPhone 17: Most people will be more than satisfied with the iPhone 17, especially with the welcome 120-Hz upgrade and boosted 256 GB of storage.
• iPhone Air: If you want to experience Apple's lightest iPhone ever, and you don't particularly use the camera all that much, you'll probably enjoy the Air.
• iPhone 17 Pro and Pro Max: You want the best Apple has to offer. If you use many of Apple's camera features and various zoom levels, these iPhones will deliver the best experience. If you're a heavy gamer, you'll also enjoy the improved thermals and extra power of the iPhone 17 Pro. For a big screen and the best battery life, buy the Pro Max. For a more reasonable phone size, get the Pro.

I always recommend you buy your iPhone unlocked. It makes switching carriers a breeze, and you'll have no hassles if you swap to an international eSIM when traveling. The iPhones sold via Apple's storefront are unlocked, with one exception: If you buy through an AT&T installment plan, your iPhone will be network-locked. Buying the iPhone 17 unlocked increases the price by $30 to $829 instead of $799, but it's well worth it.

The best place to buy an iPhone is Apple.com. You can use the Apple Store app to snag your preorder as soon as devices are available, starting at 5 am Pacific, 8 am Eastern. You can get a head start by saving your selections in the app, as long as you do it before midnight Eastern time September 12.

Don't forget to take advantage of Apple's promotions: You get three free months of Apple News+, Apple Fitness+, Apple TV+, and Apple Music. It'll auto-bill you after the trial, so set a reminder to cancel if you don't want to continue subscribing to these services.

If you must buy from a carrier, here are some promotions to consider. Many of these “deals” come in the form of monthly bill credits, designed to keep you locked to a multiyear contract.

• T-Mobile is offering up to $1,100 off any iPhone 17 and iPhone 17 Pro model, including the Air, if you trade in an eligible phone in any condition. New customers can switch to T-Mobile and get up to $830 off any iPhone 17 model. T-Mobile says you can use its T-Life app to order the iPhone 17 range instantly.
• Verizon similarly is offering up to $1,100 off an iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, or iPhone Air with an eligible trade-in, no matter the condition of the device; you'll also need to be on an eligible unlimited plan. You can also bundle an Apple Watch SE 3 or Apple Watch Series 11 (or get $500 off the Apple Watch Ultra 3), though you'll have to get a service plan for the watch.
• AT&T will cover up to $1,100 for the iPhone 17 Pro or iPhone 17 Pro Max, or up to $830 off the iPhone 17 or iPhone Air, but you'll need to trade in an eligible phone (in any condition).
• Boost Mobile customers can get up to $830 off the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, or iPhone Air if they're on the Infinite Access Plan. This promotion gets bumped up to $1,000 off if you buy from Apple.com and choose Boost Mobile at checkout.
• Best Buy offers the entire iPhone range, but these are locked to AT&T or Verizon. You can save up to $830 via an eligible trade-in for the iPhone 17 or iPhone Air, and up to $1,100 for the iPhone 17 Pro and iPhone 17 Pro Max. You also get three months of Apple TV+, Apple Arcade, Apple Music, and Apple Fitness+ with your purchase, but you'll be charged monthly after that.
