iPhone Ultra rumors: Everything you need to know about the foldable iPhone

Rumors about Apple's first foldable phone have been circulating for years, but 2026 is looking to be the year the foldable iPhone Ultra finally breaks cover. Considering the foldable phone space has been pretty small potatoes for almost a decade, this could be a turning point that edges this category closer to the mainstream — and puts Samsung's dominance at risk.

Everything we've heard points to the iPhone Ultra launching alongside the iPhone 18 Pro and iPhone 18 Pro Max during the September Apple event. Based on the rumors, we've heard that the iPhone Ultra will have a short and squat passport-style design, possibly no crease at all, dual rear cameras, Touch ID and more.

Here's everything we've heard about the foldable iPhone Ultra so far.

iPhone Ultra: Rumored specs

iPhone Ultra: Price & release date estimates

The iPhone Ultra is expected to be unveiled at the Apple event this fall, which typically happens during the first or second week of September. The date that seems most likely based on the rumors is Sept. 9, which is two days after Labor Day.

This event should also see the reveal of the iPhone 18 Pro and Pro Max, both of which should be released before the end of the month. iPhone 18 and iPhone Air 2 aren't expected to make an appearance, with reports suggesting they'll be released in early 2027.

There is some debate surrounding the iPhone Ultra's release date. Some sources claim that the phone will arrive around the same time as the iPhone 18 Pro, while others suggest production issues may see the phone arrive later in the year — the same way the iPhone X did in 2017.

Whenever the phone arrives, reports suggest that supply may be limited at first, though this may not be as big an issue considering how much the phone is rumored to cost. Early estimates tipped the phone to cost around $2,000, but issues with supply chains and the rapidly rising cost of components now suggest that the iPhone Ultra price could start from $2,400 to $2,500.

iPhone Ultra: Design

The iPhone Ultra will obviously be like no iPhone that has ever been released, since it will ditch the unibody design in favor of the new folding form factor. A slew of dummy units have shown up online revealing the look and feel of the foldable, with Apple opting for a more passport-style design that is shorter and wider than traditional book-style foldable.

The closest comparable foldable is the Samsung Galaxy Z Fold 8, which adopts a similar look — but appears to be slightly larger than what we expect from Apple. It's speculated that Apple could utilize titanium to enhance the durability of the iPhone Ultra, while keeping the overall weight low — much as it did with the iPhone Air.

Reports suggest that the foldable display will be around 7.8-inches in size, which is around half an inch smaller than the iPad mini 7, with a 5.5-inch cover display. This would likely mean an aspect ratio close to 4:3, just like iPads and the Galaxy Z Fold 8, which makes the Ultra a hybrid phone/tablet.

It's also been claimed that an open iPhone Ultra could be as thin as 4.5mm, and somewhere between 9 and 9.5mm when closed. This would make it the thinnest Apple device so far, beating the 5.1mm iPad Pro. However, the Galaxy Z Fold 8 is thinner than these dimensions.

The smaller size also means that the phone only seems to have two rear cameras, while the front display will reportedly skip Face ID in favor of adding Touch ID to the power button — similar to the system Apple uses on cheaper iPad models.

Rumors about possible colors suggest that Apple will stick to muted options like black or dark gray, and either silver or white. However, there are rumors that a color similar to iPhone 17 Pro Max's Deep Blue could be available.

iPhone Ultra: Crease-free display?

The iPhone Ultra is also expected to have no visible crease. Apple was reportedly very particular about this, and it rumored to be using the crease-free display as one of the iPhone Ultra's key selling points. Reports suggest this will be reliant on a bunch of design innovations, including a more durable liquid metal hinge, ultra-thin glass, a structural glass mid-frame and optically clear adhesive.

These hardware features will apparently work in tandem to ensure that there won't be a visible crease out of the box, nor will it form with continued use. Meanwhile, Apple has apparently worked to ensure the crease depth is under 0.15mm, with a crease angle below 2.5mm. Lower depth should make the crease less noticeable, while the lower angle should offer a flatter look when the screen is unfolded.

It's unclear as to whether the "crease-free" description holds up to scrutiny. After all, the Galaxy Z Fold 8 Ultra was reportedly crease-free, and while the crease is much harder to spot, it is still there.

iPhone Ultra: Performance

We don't know a lot about the performance capabilities of the iPhone Ultra, but it goes without saying that the phone should feature an A20 chipset — which is rumored to be built on TSMC's 2nm process.

The transition from the 3nm process will allow boosted performance from the increased transistor density. Reports suggest that the A20 could be 15% faster than the A19 chips, and 30% more efficient. That means stronger performance, less heat generation and lower energy consumption. The latter is particularly important because it means the large batteries rumored to be in the iPhone Ultra should last even longer.

RAM for the iPhone Ultra is expected to be at least 12GB, simply because that's the minimum needed to utilize the full range of Siri AI features. Any less and features like improved dictation and expressive AI voice styles will not be supported on the foldable — which would be absurd for a $2,500 phone.

iPhone Ultra: Software

The iPhone Ultra is going to have to make major changes to the way iOS handles multitasking, since it's going to have to start splitting apps across a much larger area than ever before. It's a feature that works well on iPadOS, and should make the transfer to the foldable device. Likewise, I'd be surprised if we don't see a menu bar, similar to what is already available on iPads and Samsung Z Fold devices.

The fact that this iPhone Ultra will feature two wildly different screen sizes to normal non-folding devices means app developers will need to ensure their apps are better optimized. Not only for the larger foldable display, but also the smaller cover display. Apple referred to something known as "app adaptability" at WWDC 2026, and it's likely this will play a key role in iPhone Ultra app support.

This concept will likely involve ensuring apps can adjust themselves based on the size of the screen they're on — which will allow them to switch between both iPhone Ultra displays. Hopefully, this ends up being a little more robust than some Android foldable apps, which simply blow up the phone app to take up more screen space.

iOS 27 beta also features references to a "foldstate" and "angledegrees," which all but confirms that iOS 27 will need to be able to detect the exact state of a foldable's hinge. Not only does this suggest the iPhone ultra will automatically transfer contents between screens when the iPhone Ultra is opened (or closed), it also hints at a feature similar to Samsung's Flex Mode.

Flex Mode is able to split the foldable screen into two distinct areas when the hinge is fixed at a 90-degree angle. That way you can do something on one half of the screen, while the other does something completely different. This could be helpful for gaming, with a split between the touch controls and the game itself, or when watching videos on social media.

iPhone Ultra: Cameras

The one common theme with iPhone Ultra leaks is that the rear camera array will only feature two lenses — arranged horizontally on a raised camera bar like the iPhone Air. It's unlikely that either of these will be a telephoto lens, due to the foldable's thin design, which means we're likely to see the traditional pairing of main and ultrawide angle lenses.

Both lenses are expected to offer 48MP resolution, which is par the course for modern iPhone flagships. So don't expect any Samsung-style 200MP cameras on this particular foldable.

Selfie camera rumors are a little sketchy, with some rumors speculating that we could see an under-display camera on the larger folding screen. However, the exterior cover display is likely to be a standard hole-punch design which, in the absence of Face ID hardware, should be a lot smaller than the Dynamic Island pill we've already seen on iPhone 17 Pro. Resolution is tipped to be 24MP on both cameras, should we get two.

iPhone Ultra: Battery

Apple is not really one to brag about the size or makeup of its batteries, so don't expect to hear much about the iPhone Ultra's power supply until we get our first post-launch teardowns. But rumor is that Apple won't scrimp on the battery with the iPhone Ultra, despite rumors of the ultra-thin display.

It's been claimed that the battery could be 4,883 mAh, which would be similar to the Galaxy Z Fold 8's 4,800 mAh.

The question is, what sort of batteries will Apple employ? Samsung recently added silicon carbon batteries to boost the capacity in the Z 8 series of foldables, with the highest being a 5,000 mAh battery in the Z Fold 8 Ultra. Since silicon carbon offers better power density, it could allow Apple to offer such large batteries while maintaining the slim, lightweight profile of the iPhone Ultra.

Then again, Apple may also have a different idea in mind, with rumors suggesting that it could redesign the power systems to be thinner, while simultaneously adopting high-density battery cells. What we should expect to see is the total battery capacity split across to separate battery packs — one on each side of the phone.

References in iOS 27 beta suggest that a future iPhone will have more than one battery, and the Ultra makes the most sense — especially since the split battery is a common design feature in other foldables.

iPhone Ultra: What's it actually going to be called?

The name iPhone Ultra has gained popularity over the last few months, toppling the old "iPhone Fold" nickname everyone had been using. Obviously, we don't know what Apple's exact plans are, and while iPhone Fold is a very literal description of what this phone is, iPhone Ultra feels a little more fitting.

Not only is this tipped to be the most expensive iPhone ever made, Apple needs to emphasize that this device isn't just a gimmick. As descriptive as the term "Fold" is, it highlights the foldable nature of the phone while seemingly ignoring everything else. "Ultra" suggests that this is a step beyond the iPhone 18 Pro Max, and should intrigue people about the kind of things this phone can do. Or, at least, that's the way I see it.

We won't know for sure until the iPhone Ultra is unveiled at the Apple event, but until then the consensus is that Apple is opting for the "Ultra" name.

iPhone Ultra: Outlook

As we inch closer to the fall Apple Event, we're forming a much better picture of the iPhone Ultra and the kind of things it should be able to accomplish. Obviously, there are still a bunch of unknowns, and we can't form a concrete opinion until we test the phone for ourselves, but the rumors and leaks paint a fairly positive picture of Apple's very first foldable.

Then again, rumored $2,000+ price could be a major sticking point. While iPhone Ultra demand is expected to be high, the fact that it could cost more than three iPhone 17s may make shoppers think twice, even if the new Apple Upgrade leasing program is able to reduce that monthly cost.

We won't know for sure until Apple actually reveals and releases the iPhone Ultra later this year. Until then keep checking back for all the latest news and rumors about the first-ever Apple foldable.
