iPhone 18 Pro vs iPhone 17 Pro: Should You Upgrade?

For you weirdos trying to figure out whether to upgrade from the iPhone 17 Pro to the 18 Pro: what are you doing? Just kidding. You’re not alone. Let’s go through the differences, and spoiler, there’s one type of person who probably should upgrade.

Design and display

Did you spot it? The only real difference is the back glass, which is now more color-matched to the frame. The 17 Pro’s two-tone look was nice, especially in orange, but it made the Apple logo hard to see and looked a little off. Better color matching gives it a more polished feel. Otherwise it’s the same aluminum design, rounded corners, buttons, Camera Control, and basically the same dimensions. Cases for the 17 Pro fit the 18 Pro and vice versa.

On the front, the Dynamic Island is about 25% smaller and can show three Live Activities instead of two. Otherwise, the displays are the same in size, peak, HDR and outdoor brightness.

Siri and Apple Intelligence

Apple spent a lot of the keynote on intelligence, but everything the 18 Pro can do with Siri, the 17 Pro can do too. Both have the new Siri chat app, voice conversations that feel natural because you can interrupt Siri mid-answer, and the latest dictation models. To be honest, iPhone dictation still needs quite a bit of work.

Camera

The main camera is inarguably the biggest upgrade: a variable aperture you can set manually on the 1x lens, from f/1.48 to f/4, with two steps in between. f/1.48 gives a blurry background; f/4 puts more of the scene in focus. Stop down to f/4 and direct light makes distinct starbursts. Lots of people will love that; I’m not sure I will long term. You won’t really see them in automatic mode, though. In low light it uses f/1.48, which gives a brighter, more detailed image than the 17 Pro’s f/1.8.

You also get manual shutter speed, focus and white balance. I’m happy about white balance, because the iPhone can never get the color right in my room. It blows my mind that these Pro controls are exclusive to the 18 Pro. There’s no technical reason the 17 Pro shouldn’t get them; third-party apps can do it. I hope it will.

There are upgraded Photographic Styles with texture, film grain and a soft-skin look, Cinematic mode upgrades, and smart focus tracking: double-tap a subject and it stays in focus even as it runs around the frame or behind things. In the few times I’ve used it, it’s been more accurate than my actual cameras. My kid is pretty much grown up, but for young kids running around the yard it’ll be fantastic.

In everyday automatic shooting, you’ll have a hard time seeing differences unless you compare side by side.

Performance

A19 Pro to A20 Pro is a 20–40% jump, staggering for one year. In everyday use (apps, social media, email, browsing, videos, any App Store game) I don’t see any difference at all. You can see it in benchmarks, but the only non-benchmark I found was on-device image generation, and the 18 Pro was only 15 seconds faster, both around two minutes. It makes me miss the iPhones of ten years ago, when a one-year jump was something you could feel.

Battery

The battery is about 10% larger, and Apple says 33 hours of video playback versus 36. I think the difference comes from the bigger battery, the C2 modem replacing the 17 Pro’s Qualcomm modem, and the more efficient 2 nm A20 Pro. Apple says the 18 Pro has basically the battery of the 17 Pro Max. I disagree; I get a little more time and a little less battery anxiety, but it’s not drastic. Yesterday I used 94% with 6 hours 15 minutes of screen time; last Wednesday 63% with 4 hours 42. I’d say I average around six hours and about 80%.

Should you upgrade?

The changes are small. If there was ever a reason for an “S” iPhone, like an iPhone 17S, this is it. The one type of person who should upgrade is someone who already upgrades every year through a carrier or upgrade plan because they enjoy it. If you enjoy something, go ahead. Feature-wise and financially, it makes absolutely no sense.

If you’re on a non-Pro iPhone 16 or older, you’ll see a good jump. From a 14 Pro or older, a big one. And if you’re dying for Pro controls, let me save you about a thousand dollars: a $15–20 third-party camera app gives you the same controls.
