iPhone 18 Pro vs iPhone Air: which should you choose?

If you were to arrange Apple's current crop of iPhones in terms of price, the iPhone 18 Pro and iPhone Air would sit squarely in the middle of the pack. They're more expensive than the iPhone 17 and iPhone 17e, but cheaper than the iPhone 18 Pro Max and iPhone Duo.

Generally speaking, these two devices are for people who want something special from their phones, but don’t quite want to spend top-end money — or simply don’t want the massive (or foldable) screens that Apple’s priciest handsets come with.

But the iPhone 18 Pro and iPhone Air are also quite different in a lot of ways. One delivers pro-level features and market-leading camera performance; the other offers a comfortable and stylish design. So which should you choose?

Below, we've detailed the key differences between the iPhone 18 Pro and iPhone Air to help you figure out which device is best for you.

iPhone 18 Pro vs iPhone Air: specs comparison

The table below gives you a brief overview of these two handsets; then, under that, we’ll look more closely at what makes them tick.

iPhone 18 Pro vs iPhone Air: price and availability

The iPhone 18 Pro launched in September 2026, and it’s available globally. It starts at $1,199 / £1,199 / AU$2,099, for which you’ll get a model with 256GB of storage. 512GB will set you back $1,399 / £1,399 / AU$2,499, 1TB costs $1,799 / £1,799 / AU$3,299, and a 2TB model is $2,399 / £2,399 / AU$4,499.

The iPhone Air launched back in September 2025, so it’s a year older but doesn’t yet have a successor. It too is widely available, and it costs $1,099 / £1,099 / AU$1,899 for 256GB of storage, $1,299 / £1,299 / AU$2,299 for 512GB, and $1,699 / £1,699 / AU$3,099 for 1TB — there's no 2TB variant of the iPhone Air.

So, the starting price of the iPhone 18 Pro is $100 / £100 / AU$200 higher than that of the Air, and that difference is consistent for each configuration. Importantly, though, the Air is often on sale, so you're unlikely to need to pay full price.

It's worth noting, too, that the iPhone Air was actually priced at $999 / £999 / AU$1,799 at launch, but Apple increased its price following the launch of the iPhone 18 Pro in September, just as it raised the price of iPads and MacBooks in June due to "significantly higher memory costs."

iPhone 18 Pro vs iPhone Air: design

Notwithstanding their display size differences (more on that below), the iPhone 18 Pro and iPhone Air look similar from the front, offering flat screens, minimal bezels, and Dynamic Island cut-outs at the top of their respective displays.

The Dynamic Island on the iPhone 18 Pro is actually a touch smaller than the Air's, and it can display three Live Activities simultaneously instead of two, but this isn't a particularly consequential difference.

From the back, there are more visible differences between the two phones. The iPhone Air is made from a single slab of glass surrounded by a titanium frame, while the iPhone 18 Pro has a glass panel surrounded by an aluminum frame.

Their respective camera layouts are different too, with the iPhone 18 Pro having a much larger triple-lens block compared to the iPhone Air’s slimmer, single-lens camera island.

But the biggest design differences come in the two phones' dimensions and weights. The iPhone 18 Pro measures 150 x 71.9 x 8.8mm and weighs 211g, while the iPhone Air measures 156.2 x 74.7 x 5.6mm and weighs 165g.

Those are substantial differences — the iPhone Air is far slimmer and lighter than the iPhone 18 Pro, which is, of course, the whole point of the phone. It feels much more comfortable to hold in the hand and carry around in your pocket, despite being taller and wider.

Having a thin and lightweight phone might not matter all that much to you, in which case you probably won't care for the iPhone Air's design. But I'd urge you to at least hold Apple's super-slim iPhone in your hand before disregarding it — it genuinely is a lovely device to use day-to-day, and TechRadar's Phones Editor, Axel Metz, was surprised by how much he came to appreciate the Air's design in testing.

The iPhone 18 Pro is, of course, still an attractive and well-designed phone, but it's significantly bulkier and doesn't excite in the same way as the Air — at least on the design front.

For colors, the iPhone 18 Pro comes in Black, Silver, Glacier, and Burgundy, while the iPhone Air is sold in Space Black, Cloud White, Light Gold, and Sky Blue. So there are some differences there too.

Both phones, though, are similarly durable, offering Ceramic Shield 2 protection on the front and Ceramic Shield on the back, along with IP68 water and dust resistance.

iPhone 18 Pro vs iPhone Air: display

The iPhone 18 Pro has a 6.3-inch 1206 x 2622 Super Retina XDR OLED screen with around 460 pixels per inch, a 120Hz refresh rate, and a peak brightness of 3,000 nits.

On the iPhone Air, you’re getting a 6.5-inch 1260 x 2736 Super Retina XDR OLED display with roughly 460 pixels per inch, a 120Hz refresh rate, and a peak brightness of 3,000 nits.

So the specs here are almost identical, with the main difference just being that the iPhone Air has a slightly larger display — though as noted earlier, the iPhone 18 Pro does have a smaller Dynamic Island.

Our reviews described both screens as “punchy, sharp, and smooth,” so there’s really very little to choose here. Do you prefer a bigger display, or a more compact one?

iPhone 18 Pro vs iPhone Air: cameras

There’s a clear winner when it comes to cameras and, unsurprisingly, it’s the iPhone 18 Pro: this device has three lenses on the back — a 48MP variable aperture main camera, a 48MP ultra-wide with a 120-degree field of view, and a 48MP telephoto with 4x optical zoom and 8x ‘optical-quality’ zoom, achieved through a sensor crop.

The iPhone Air, meanwhile, just has a single 48MP wide camera with a static f/1.6 aperture. In other words, you have far less photographic versatility with this phone, which you'll notice when filming at concerts, sports games, or basically anywhere that might have you attempting to capture a subject from far away.

That's not to say the iPhone Air is a bad camera phone — its 48MP wide camera is the same as the 18 Pro's, minus the latter's variable aperture feature (which lets you tweak how much light gets into the lens). If you use your phone's main lens for 90% of shots, you may not notice the Air's lack of versatility.

But the iPhone 18 Pro is indisputably one of the best camera phones you can buy, while the iPhone Air falls into the 'good but not great' category.

Still, the Air does at least match the iPhone 18 Pro’s selfie camera, with both devices sporting an 18MP front-facing sensor. Both can also record 1080p video at up to 240fps, though the Pro can additionally record 4K footage at up to 120fps, while the iPhone Air tops out at 60fps.

In our iPhone 18 Pro review, we described its cameras as delivering “better detail, strong low-light performance, and excellent 4x and 8x zoom.” Of the iPhone Air, we said it “delivers sharp, natural photos and impressive portraits, but lacks the versatility found on other models.”

iPhone 18 Pro vs iPhone Air: performance and software

As for power, you'll technically get better performance from the iPhone 18 Pro, with Apple's newer phone boasting — surprise! — a newer A20 Pro chipset than the iPhone Air's A19 Pro chipset.

Still, you're not likely to notice this power difference unless you plan on using your phone for heavy video editing or prolonged gaming. Both the iPhone 18 Pro and iPhone Air feature 12GB of RAM, so their multitasking capabilities are comparable, while scrolling, streaming, and browsing won't present a challenge to either device.

Our iPhone 18 Pro review called Apple's newer phone “fast, efficient, and ready for whatever comes next”, and we said the iPhone Air was “fast and smooth in daily use, though it can warm up under sustained heavy gaming.”

There’s even less difference between the two phones when it comes to software, as both run iOS 27. Their shared 12GB RAM capacity also means both phones get the full version of Siri AI, which includes expressive voices and advanced dictation.

However, since the iPhone Air shipped with iOS 26 at launch and is a slightly older phone, it’s possible that it won’t be updated for quite as long as the iPhone 18 Pro (read: you'll probably get six more years of updates, instead of seven).

iPhone 18 Pro vs iPhone Air: battery

You probably wouldn’t expect a massive battery in a phone as slim as the iPhone Air, and you’d be right not to: the Air has a dinky 3,149mAh cell, which is dwarfed by the iPhone 18 Pro's 4,288mAh one (you'll get a slightly smaller 4,056mAh battery if your iPhone 18 Pro features a physical SIM tray).

In practice, Apple claims the iPhone 18 Pro can make it through 34 hours of video playback, while it lists just 27 hours for the iPhone Air. Those figures proved accurate in our testing, and the gap between the two phones is similar for real-world use — you'll get around a day-and-a-half of life from the 18 Pro, and no more than a day for the Air.

The iPhone 18 Pro also charges faster, with Apple claiming it can reach 50% in around 15 minutes, while the iPhone Air takes twice as long — though with wireless charging, both phones can supposedly charge to 50% in 30 minutes.

In our iPhone 18 Pro review, we praised its “outstanding endurance,” while in our iPhone Air review, we said it “should last a workday, but heavy users will need to recharge.” We've used both phones extensively, and haven't found the iPhone Air's one-day battery life to be a dealbreaker — but those who don't charge their phone every night may be caught short by its lack of endurance.

iPhone 18 Pro vs iPhone Air: verdict

If you go simply by our review scores, the iPhone 18 Pro is the better phone, achieving five stars to the iPhone Air's four. And looking at the specs, it’s clear why — the iPhone 18 Pro has better battery life, more power, and more cameras, so it’s clearly the more capable device.

However, there’s little to choose between the two phones' screens, other than the size — with the iPhone Air’s being bigger. And they run the same software too, on top of which the iPhone Air is slightly cheaper (especially if you can pick it up at a discount).

But the real reason you might want the Air is its design — it's far slimmer and lighter than the iPhone 18 Pro, which makes a difference in your hand and pocket, and also makes it the more stylish device. Whether that makes up for its relative shortcomings elsewhere will be a personal choice.
