Apple set off a tectonic shift in the iPhone world last year when it added a new device – and a new naming scheme – to the iPhone 14 lineup with the iPhone 14 Plus.

Originally believed to be the 'iPhone 14 Max' and designed to complement the sizeable iPhone 14 Pro Max with a simpler chip, display and camera system, the 14 Plus also showed that Apple wasn't beyond reworking its product names for better clarity.

Rumors now suggest that the company will apply a similar treatment to the top of 2023's iPhone 15 lineup. Instead of the iPhone 15 Pro Max, it's starting to look like we might be introduced to an 'iPhone 15 Ultra', set to sit above the iPhone 15 Pro. 

The naming is not out-of-character for Apple. The company just launched an extreme version of its smartwatch – loaded to the gills with features – called the Apple Watch Ultra, and it's likely that the 15 Ultra will be more than just a bigger screen and battery, as is the case with the current iPhone 14 Pro and Pro Max.

That said, there's no guarantee we'll see an iPhone 15 Ultra at all – with one source claiming we'll be waiting until the iPhone 16 for an Ultra model, and that it will actually sit above the Pro Max, rather than replacing it. In any case, you'll find all the latest leaks and rumors about both possible phones below.

Cut to the chase

• What is it? The biggest and baddest of Apple’s expected 2023 iPhones
• When is it out? Likely either September 2023 or September 2024
• How much will it cost? Probably even more than the iPhone 14 Pro Max

iPhone 15 Ultra release date

Apple events historically happen in the first or second week of September. The company likes to make an announcement on a Tuesday or Wednesday, then start pre-sales the same Friday. The phone usually arrives in stores the Friday following.

For the iPhone 14, that event fell on September 7 (admittedly, earlier than expected), with three of the four phones going on sale over a week later, on September 16 (the iPhone 14 Plus arrived on October 7). 

In 2023, that means September 5 or 12 are likely event dates (both are Tuesdays), though the 6 and 13 are possibilities, too. We could see the phone in stores as early as September 15. 

That all assumes that there is an iPhone 15 Ultra, of course, but one leak suggests we won't see the first Ultra model until 2024 – meaning it would likely launch in September 2024 as the iPhone 16 Ultra.

iPhone 15 Ultra price

• iPhone 14 Pro Max: $1,099 / £1,199 / AU$1,899
• Samsung Galaxy S22 Ultra 5G: $1,199.99 / £1,149 / AU$1,849
• iPhone 15 Ultra (expected): $1,199 / £1,309 / AU$2,099 – $1,299 / £1,429 / AU$2,249

The early leaks about how Apple will price the iPhone 15 Ultra are telling: Apple may start the Ultra phone at $1,199. This would put the phone in the same pricing tier as Samsung's current “Ultra” device, the Galaxy S23 Ultra. That phone starts at $1,199.99 / £1,249 / AU$1,949.

However, a more recent leak suggests it could be even pricier, at $1,299, likely equating to £1,429 / AU$2,249 in other regions.

The current iPhone 14 Pro Max costs $1,099 / £1,199 / AU$1,899, which itself represents a price hike outside of the US market over last year's model. We think it's possible that when Apple switches from 'Pro Max' to 'Ultra', or adds an Ultra above the Pro Max as the case may be, it will bump the price by $100 or $200 in the US with corresponding price hikes elsewhere.

Whatever the case, a price increase of some amount seems likely, with even Apple itself suggesting that customers could be willing to pay more.

Hopefully, that price increase will also come with more reasons to buy. The current iPhone 14 Pro Max gives you a bigger screen and battery than the standard 14 Pro, and that's it. That's a big bonus for $100, but if Apple is going to push the price even higher, it needs to offer more features and more hardware to justify the price.

Fortunately, one source claims that the starting capacity will be 256GB, which is double the starting size of current models, and would go some way to justifying the price.

iPhone 15 Ultra news and leaks

We've already heard quite a bit about the expected iPhone 15 lineup, with rumors reaching back to before the iPhone 14 series' launch. However, only recently has news of a higher-tier Apple iPhone 15 Ultra emerged. Bloomberg's Mark Gurman mentioned, right after launch of the 14 line, that an Ultra would be coming, and that was the first we' heard of this new possible nomenclature.

After that, we heard further confirmation from other iPhone 15 leaks, and one leaker suggested that, in addition to a bigger screen and battery, the iPhone 15 Ultra could see a better camera setup than its iPhone 15 Pro sibling.

The information came across rather vague, with the leak saying that Apple was testing a much-anticipated 8K video recording feature for its next iPhone, but the leaker was unsure if this feature would be coming to the iPhone 15 Pro or just the higher-end iPhone 15 Ultra. This set off speculation that the Ultra phone could see camera improvements over the Pro.

On that front, we've specifically now heard that the iPhone 15 Ultra might at least have more advanced image processing skills than the iPhone 15 Pro.

Unofficial renderings showing off the iPhone 15 Ultra/iPhone 15 Pro Max have now shown up online, and there's not much change from the iPhone 14 Pro Max: there's a USB-C port, and a slightly shallower camera bump, and the edges of the chassis look like they're going to be a little more curved.

We've also seen screen glass leaked on video for three of the iPhone 15 models, and the largest one shown is supposedly the Ultra. It has a Dynamic Island, as you'd expect, along with tiny bezels that are slightly curved.

Samsung's Galaxy S22 Ultra is a step ahead of its Galaxy S22 Plus and base model Galaxy S22, and one significant improvement is the addition of a periscope-style telephoto zoom lens. Leaks suggest Apple could also use a periscope zoom on its larger Ultra device, and size requirements for such a lens would make more sense on the larger phone compared to the smaller iPhone 15 Pro that is expected next fall too.

Another camera upgrade could come in the form of a new Sony sensor that apparently captures more light and is better at avoiding overexposing or underexposing shots than current smartphone cameras, even in tricky scenes where the foreground lighting is very different to the background.

We've also heard that the Ultra might have a dual-lens front-facing camera, with the same source saying it might only come in one shade – the same silver color as the Apple Watch Ultra.

Elsewhere, there's a reputable source claiming that the Pro models of the iPhone 15 line (presumably including the iPhone 15 Ultra) will get a USB-C port with support for data transfer speeds of up to either 20Gbps or 40Gbps, up from just 480Mbps on current iPhones. We've heard similar claims from multiple sources now. We're also expecting Wi-Fi 6E support on this phone.

Of course, it's sure to be very powerful, too. Expect an A17 Bionic chipset, which a source claims might be a lot more efficient than the A16 Bionic used by the iPhone 14 Pro line, which could in turn lead to better battery life.

It might even be more powerful than the same chipset in the iPhone 15 Pro, with one source claiming the software won't limit the chipset as much on the Ultra. The only real reason the software would limit it in the first place is to stop the phone overheating, so that also suggests the iPhone 15 Ultra might have a better cooling system.

Beyond that, we've also heard that the iPhone 15 Ultra might be clad in titanium, which is typically stronger and lighter than the stainless steel used by the iPhone 14 Pro Max. This claim comes from a tweet by leaker LeaksApplePro, who isn't one of the biggest leakers but has been right before.

Another source has now said the same, so this might well be true. This second source has added that the sides will apparently be a different shape too, with them curving in to the rear of the phone, rather than being a right angle.

More evidence of that comes from the image above, which reportedly shows an iPhone 15 Pro with brushed metal sides, which are likely titanium, and with curvier edges than current models. So while that's a different phone, the same design changes may well come to the iPhone 15 Ultra as well.

This image additionally shows a USB-C port, adding credence to the claims that we'll see such a port on the upcoming iPhones.

A further rumor has suggested that the iPhone 15 Pro and the iPhone 15 Ultra are going to have thinner bezels than their predecessors, and that all the models in the range are set to have curved edges.

Also on the design front, the iPhone 15 Ultra was widely rumored to get solid-state volume and power buttons. Leaks had suggested that these buttons would use vibrations to simulate the sensation of being touched despite not actually moving (think the iPhone 7’s haptic Home button), but analysts Jeff Pu and Ming-Chi Kuo recently poured water on those claims. 

According to Pu, Apple needs more time to develop the haptic engines required to power these new buttons, with Kuo adding that their removal from the iPhone 15 Ultra (and iPhone 15 Pro) “will simplify the development and testing process.”

Given the technical intricacy of capacitive buttons, though, Apple’s supposed decision to kick the can down the road is understandable. 

On top of the haptic engines cited by Pu, another leaker had previously claimed that a dedicated microprocessor would support the iPhone 15 Ultra's solid-state buttons, rendering them capable of detecting touches even when the device is switched off. The microprocessor in question was purported to replace the Super Low Energy Mode currently used in the iPhone 14 Pro, which allows apps like Find My and Apple Pay to function with next to no power. 

In other words: solid-state power buttons are complex beasts – but we’ll hopefully see them introduced in 2024 with the iPhone 16 Pro and iPhone 16 Ultra, if not this year’s iPhone 15 range.
