Is It Time to Upgrade to the iPhone 17? How Older iPhones Compare

The arrival of the iPhone 17 might have you wondering if it's time to swap your older Apple device for the latest model. Depending on your current iPhone, getting the iPhone 17 could be a notable step up.

The iPhone 17 starts at $829, or $799 if you activate through a carrier. But unlike previous generations, the lowest storage option is 256GB, which is a nice upgrade from the previous 128GB starting point.

Several noteworthy updates to the iPhone 17 make it feel like a tempting choice, even over the pricier iPhone 17 Pro models. At long last, Apple has extended a 1-120Hz display across its entire lineup, so you can have smoother scrolling and an always-on display without spending upwards of $1,100 on a Pro model. An anti-reflective coating and higher 3,000-nit peak brightness make the screen slightly easier to see outdoors. And camera upgrades help to level up photos and selfies. 

Here's how the iPhone 17 compares to older iPhones, ranging from last year's iPhone 16 to 2020's iPhone 12.

The iPhone 16

iPhone 17 vs. iPhone 16

Appearance-wise, the iPhone 17 has a lot in common with the iPhone 16. But beneath the surface, there are some key differences. 

The display goes from a meager 60Hz on the iPhone 16 to 120Hz on the iPhone 17 (at long last). That means the iPhone 17 finally supports an always-on display, so you can glance at the time and your notifications without waking the screen and enjoy smoother scrolling. A new anti-reflective coating helps reduce glare, especially in the bright outdoor conditions. 

The iPhone 17 has a larger 6.3-inch display, versus the iPhone 16's 6.1-inch screen, thanks to slimmer bezels. That can make viewing content slightly more immersive, though it won't be a hugely noticeable difference. And a new Ceramic Shield 2 cover on the iPhone 17 offers three times better scratch resistance, according to Apple, so you can worry a little less about etching into your phone's screen (but maybe still get a screen protector to be safe).

The iPhone 16 and 17 have a 48-megapixel wide-angle camera, but the iPhone 17 bumps the ultrawide camera from 12 megapixels to 48 megapixels. The front-facing camera also gets upgraded from 12 megapixels (on the iPhone 16) to 18 megapixels on the iPhone 17. Both phones have a Camera Control button for quickly launching the camera and snapping photos.

A new Center Stage feature can automatically adjust selfie photos from portrait orientation to landscape to ensure everyone is in the shot, so you don't have to manually rotate your phone to its side anymore. Dual Capture lets you simultaneously record on your front and back cameras. These upgrades are specifically catered to the latest iPhone lineup, so that they won't be coming to older models like the iPhone 16, even with an iOS 26 update.

Battery life is a little longer on the iPhone 17. Apple says the iPhone 17 supports up to 8 hours more of video playback than the iPhone 16. This change aligns with improvements CNET noticed in our battery tests. In a 3-hour streaming test, for example, the iPhone 17's battery dropped from 100% to 89%, while the iPhone 16 hit 86%. It's an incremental update, but even a little more battery life is a welcome change. The iPhone 17 also supports up to 40-watt charging, which is a boost over the 25 watts you get with the iPhone 16, helping you top off your battery a little faster.

The bottom line: While the updates to the iPhone 17 help it stand out as an all-around solid device, the changes over last year's iPhone 16 are incremental enough that there's not much reason to upgrade -- unless you're really excited about that smoother display and faster charging. But for most people, subtle differences mean you should probably just hold onto your iPhone 16. 

The iPhone 15

iPhone 17 vs. iPhone 15

The iPhone 15 has a lot in common with the iPhone 16, including a 48-megapixel wide-angle camera, a 12-megapixel ultrawide camera and a 6.1-inch display. The 6.3-inch display on the iPhone 17 has slimmer bezels to expand that real estate a bit, and the 48-megapixel ultrawide camera can lead to slightly sharper shots.

The baseline iPhone 15 doesn't have an Action button that you can customize to launch various apps and functions, and instead has the more traditional ring/silent switch. The iPhone 17 has an Action button and a Camera Control button.

Both phones have a Dynamic Island cutout at the top of the display for showing alerts and Live Activities, such as the time your DoorDash order is arriving, flight updates and what song is currently playing.

With each generation, Apple touts longer battery life, so you can expect to get a couple more hours of video playback with the iPhone 17 than you would with the 15.

Perhaps the most significant difference between the iPhone 15 and 17 is that the iPhone 15 doesn't have Apple Intelligence; those AI features only arrived on that year's Pro models. If you upgrade to the iPhone 17, you'll have access to writing and image editing tools, as well as newer features like Live Translation for calls and messages. 

The bottom line: Like the iPhone 16, there aren't many drastic differences between the iPhone 15 and 17, though upgrading will notably grant you access to Apple Intelligence. But the other hardware and software-related updates are relatively minimal, so you're probably good keeping your iPhone 15 for at least another year.

The iPhone 14

iPhone 17 vs. iPhone 14

The iPhone 14 was the last Apple phone with a Lightning port and that's one of most significant differences between it and the iPhone 17, which has a USB-C port. Upgrading to the iPhone 17 means you won't have to rely on an outdated and limited-use charging cable anymore, and can instead use one that works with most of your other devices. 

The baseline iPhone 14 also doesn't have a Dynamic Island cutout in the display, as that feature launched with just the Pro models that year. Upgrading to the iPhone 17 will let you quickly tap into activities like your rideshare trip or flight information.

The iPhone 14 has a 12-megapixel wide and ultrawide-angle camera on the back, while the iPhone 17 bumps that to 48 megapixels across the board. The iPhone 17 also increases the front-facing camera's resolution from 12 megapixels to 18 megapixels, while adding a new Center Stage selfie feature to automatically adjust between portrait and landscape images without you having to rotate your phone. 

But the two phones also some key similarities, like having eSIM and satellite connectivity on board.

The bottom line: The iPhone 14 has the most noticeable differences with the iPhone 17. Upgrading could offer some fresh features like an Action button and, at last, a USB-C port, as well as Dynamic Island and an upgraded camera. But if you want to save some money and keep your current phone, you won't be missing out on anything too drastic.

The iPhone 13

iPhone 17 vs. iPhone 13

The iPhone 13 has a similar A15 Bionic chip as the iPhone 14, and shares the same dual 12-megapixel camera system. But unlike the iPhone 14, the iPhone 13 doesn't have crash detection or satellite connectivity, or camera features like Action mode for more stable videos. 

At this point, your iPhone 13 may be showing its age. Upgrading to the iPhone 17 will give you access to newer features like Apple Intelligence, Dynamic Island, USB-C charging and the Camera Control and Action buttons. You might also notice faster speeds by switching to the iPhone 17, now that it's been a few years since the iPhone 13 came out.

The bottom line: It may be time to upgrade to the iPhone 17 if you have an iPhone 13. It's possible your phone is starting to show its age, and switching to Apple's latest baseline will get you a longer-lasting battery, an upgraded camera, AI features and a handful of new hardware and software capabilities. 

The iPhone 12

iPhone 17 vs. iPhone 12

Like the next couple of iPhones after it, the iPhone 12 has a dual 12-megapixel camera system, as well as a 6.1-inch display. Upgrading to the iPhone 17 will get you a slightly more immersive 6.3-inch display with thinner bezels, along with a 48-megapixel dual camera system. 

The iPhone 12 lacks features like crash detection, satellite connectivity, Dynamic Island and USB-C charging. It also doesn't support the Apple Intelligence suite of AI features for writing, photo editing, language translation and more. 

It's possible your iPhone 12 has become sluggish and your battery isn't holding up like it used to. Taking age out of the equation, at launch, the iPhone 12 boasted up to 17 hours of video playback, while Apple says the iPhone 17 supports up to 30 hours. So there's likely to be a noticeable difference between how long each phone can hold up.

The bottom line: Swapping your iPhone 12 for the iPhone 17 could be a smart move. There have been noticeable changes over the last several years, from the addition of the Action and Camera Control buttons to the introduction of Apple Intelligence. The swap to USB-C and expanded battery capacity can also make the newest iPhone more tempting; you won't have to cling to your now-outdated Lightning cable. And you'll likely notice faster speeds and higher performance across the board when switching from a 5-year-old device to the latest generation.
