The iPhone 18 Pro is expected in September 2026, and the volume of leaks is already enormous. Apple watchers including MacRumors and 9to5Mac are running weekly roundups, and the picture they paint is one of the more substantial Pro upgrades in years. Several of the changes are the kind people have asked Apple for repeatedly.

Here are the ten changes the leaks point to, what each one means in practice, and whether any of them is a reason to wait rather than buy an iPhone 17 Pro Max now.

The most-reported change is Face ID moving under the display. The sensors that currently sit in the Dynamic Island would be hidden beneath the screen, leaving only a single small camera cutout. The result is a cleaner, more screen-filling front.

Why it matters: this is the most visible design change to the iPhone’s front in years. If you have wanted the notch and cutout gone, this is the upgrade that does it. It is a cosmetic and immersion improvement rather than a functional one, but it is the change you will see every time you look at the phone.

Leaks point to a variable aperture on the main camera, a mechanism that physically changes how much light the lens lets in. Today’s iPhones have a fixed aperture and simulate background blur in software. A variable aperture does it optically.

In practice this means more genuine control over depth of field: sharper, deeper-focus landscapes when you want everything crisp, and more natural, hardware-driven background blur for portraits. For anyone who cares about photography, this is one of the most meaningful upgrades on the list because it changes what the camera can actually do, not just how fast it does it.

The iPhone 18 Pro is expected to run the A20 Pro, reportedly built on a 2nm process. The headline benefit is efficiency: more performance for the same battery, or the same performance for longer before the battery runs down or the phone throttles.

This is the same process leap rumoured for Google’s Tensor G6, so 2026 is shaping up to be the year the newest flagships all move to 2nm. For most users the day-to-day effect is better sustained performance and battery life rather than raw speed, since current iPhones are already fast enough for almost everything.

Among the colour leaks, a deep red finish stands out. Apple has not offered a bold red on the Pro line for some time, and if accurate it would be the standout colour of the launch. Colour is a small thing on paper but a real factor for many buyers, and a distinctive new shade tends to drive early demand for a particular model.

The front camera is reported to jump to 24MP, double the resolution of recent models. For anyone who takes a lot of selfies, shoots video calls, or vlogs and records to the front camera, this is a practical, noticeable upgrade rather than a spec-sheet one. Sharper front-camera video in particular benefits anyone who creates content or takes a lot of video calls.

Sustained performance under heavy load has been a weak point for recent iPhones, with the phone slowing down to manage heat during long gaming or video-export sessions. Leaks suggest a redesigned thermal system to keep the A20 Pro running at full speed for longer.

This matters most to gamers, video editors and anyone who pushes the phone hard for extended periods. If you only browse, message and take photos, you will rarely notice it. If you game or edit on your phone, it could be one of the more valuable changes.

Apple’s first foldable iPhone is rumoured to launch on the same stage (see our separate article). It will not compete with the 18 Pro on price, reportedly starting at $2,000 or more, but it will share the spotlight and pull much of the early-adopter attention.

For most buyers the practical takeaway is simple: the iPhone 18 Pro, not the Fold, will be the sensible flagship choice. The Fold is a halo product for people who specifically want a foldable and accept first-generation trade-offs.

UK pricing has not leaked. As a reference point, today’s iPhone 17 Pro Max sits at the top of Apple’s current range, and the 18 Pro would launch in the same bracket. Expect the 17 Pro Max to drop in price the day the 18 Pro is announced, which is what makes the current model such a strong value buy in the weeks after a launch.

Apple has launched its flagship iPhones in September for years, and nothing in the leaks suggests a change. Expect an announcement in the first half of the month, with phones on sale within one to two weeks of the event. If you are planning around the launch, mid-September is the window to watch.

The deciding question. Here is the simple version.

Wait if you want under-display Face ID, the variable aperture camera or the 24MP front camera, and you are happy to hold out until September. These are genuine, user-facing upgrades rather than spec-sheet filler, and they are the best reasons in years to wait for a new Pro.

Buy a 17 Pro Max now if you need a phone today, or if you want the best price. A current-generation flagship at a post-launch discount is one of the best-value buys in phones, and the iPhone 17 Pro Max is an excellent phone that does not suddenly get worse when the 18 Pro arrives.

It is worth being clear about how much weight to put on all of this. iPhone leaks follow a familiar pattern each year. Supply-chain reports about components and chips tend to be the most reliable, because parts are ordered months ahead and many companies see them. Design and colour leaks are more variable, since Apple often tests several options and only finalises late. Pricing is usually the last thing to leak and the least certain.

The features in this article have appeared across multiple independent sources, which raises confidence in the broad strokes. But until Apple stands on stage in September, treat every specific as a well-sourced expectation rather than a fact. The closer we get to launch, the firmer these details will become, and we will update this article as they do.

A rumour-stage comparison, to be confirmed in September. The 17 Pro Max column is current; the 18 Pro column is based on leaks.

When is the iPhone 18 Pro release date?
The leaks point to September 2026, in line with Apple’s usual flagship timing. Apple has not confirmed a date.

How much will the iPhone 18 Pro cost in the UK?
UK pricing has not leaked. Expect it to launch in the same bracket as the current iPhone 17 Pro Max, at the top of Apple’s range.

What is the biggest upgrade on the iPhone 18 Pro?
The two changes most likely to matter day to day are under-display Face ID, which transforms the look of the front, and the variable aperture main camera, which gives real optical control over depth of field.

Should I buy the iPhone 17 Pro Max or wait for the 18 Pro?
Buy the 17 Pro Max now if you need a phone today or want the best price, as it will be discounted when the 18 Pro launches. Wait if you specifically want under-display Face ID, the variable aperture camera or the 24MP front camera.

Is the iPhone 18 Pro getting a new design?
The most significant design change is under-display Face ID, which removes most of the front cutout. A new deep red finish is also rumoured.

• Confirmed UK pricing
• Whether all ten of these changes make the final cut
• Exact battery capacities
• Storage tiers and starting capacity
• Any changes to the telephoto and ultrawide cameras

We will rewrite this article the week of Apple’s September event with the confirmed details.

The iPhone 18 Pro is shaping up to be one of the more substantial Pro upgrades in years - under-display Face ID and the variable aperture camera are the genuine reasons to wait. But none of it is official until September, and the current iPhone 17 Pro Max remains an excellent buy that only gets cheaper when the 18 Pro lands. Wait if you want the new camera and design; buy now if you want the best price.
