Apple is expected to unveil its next flagship iPhones in the coming weeks, with the iPhone 18 Pro and an all-new iPhone Ultra leading the lineup. While pricing will obviously give the Pro models an advantage, several other rumored differences could make the iPhone 18 Pro more compelling for many buyers. Here are four advantages the iPhone 18 Pro is rumored to have over the more expensive iPhone Ultra, plus one intangible factor that shouldn't be overlooked.

Key facts

• iPhone 18 Pro is expected to get a variable main camera aperture, while iPhone Ultra may not.
• iPhone 18 Pro Max is expected to have a larger battery and better efficiency than iPhone Ultra.
• iPhone Ultra may rely on Touch ID instead of Face ID.
• Only iPhone 18 Pro and Pro Max are expected to have a telephoto camera.

1: Main camera with variable aperture

Variable aperture has been a long-rumored upgrade for the iPhone camera system, and the iPhone 18 Pro is now expected to introduce it. A variable aperture means the camera can physically change the size of the lens opening to control the amount of light reaching the sensor. Most smartphone cameras use a fixed aperture, so this would be a significant improvement in both flexibility and image quality.

Variable aperture could bring real benefits to Portrait mode. By narrowing the aperture, Apple could produce sharper portraits with more of the subject in focus. By opening the aperture wider, the system could create a more dramatic blurred background while allowing more light to hit the sensor. Low-light photography would also benefit, as a wider aperture lets in more light and reduces the need for long exposure times or aggressive noise reduction.

The main obstacle is physical space. The mechanical components needed to adjust the aperture are larger than the fixed lens assembly used today. Apple's iPhone Ultra is reportedly being designed as an extremely thin foldable, and that sleek chassis may not have enough room for the additional hardware. This is why rumors suggest the variable aperture will be exclusive to the Pro models. It also reinforces the idea that Apple is willing to make trade-offs in the Ultra to achieve a distinctive thin design.

2: Longer battery life on Pro Max

Battery life is another area where the iPhone 18 Pro Max is expected to shine. The Pro Max is rumored to receive a 10% larger physical battery than the current iPhone 17 Pro Max. Combined with more efficient chipsets, including the A20 Pro and the C2 modem, the new flagship could deliver the best battery life ever seen in an iPhone.

The iPhone Ultra, by contrast, will have to balance battery capacity with its thin and foldable form factor. Folding displays and mechanical hinges take up internal space, which leaves less room for a massive battery. While regulatory leaks suggest the Ultra will offer respectable battery life, it is unlikely to match the outright endurance of the iPhone 18 Pro Max.

Larger batteries alone do not tell the whole story. Software optimization and chip efficiency play a major role, and the A20 Pro is expected to be a significant step forward. The iPhone 18 Pro Max will also benefit from the new C2 modem, which could improve connectivity while drawing less power. For users who care about all-day battery life, the Pro Max remains the safer choice.

3: Face ID

For the first time in years, a new flagship iPhone could launch without Face ID. The iPhone Ultra is expected to use Touch ID instead, because its ultra-thin design reportedly cannot accommodate the TrueDepth camera array used for facial recognition. Supporting Face ID on a foldable would also be complicated by the need for two separate systems: one for the outer display and one for the inner display.

The iPhone 18 Pro will stick with Face ID, which has been a staple of the iPhone experience for nearly a decade. Facial recognition is fast, works in more situations, and supports features like Animoji, FaceTime attention correction, and secure payments. Touch ID is still reliable, but it requires a finger on a sensor and does not offer the same hands-free convenience.

This is a key advantage for the Pro line, especially for users who have come to rely on Face ID in their daily routine. The Ultra's design compromises might make sense for someone who values a foldable display, but it comes at the cost of biometric authentication that many iPhone owners take for granted.

4: Telephoto camera

The telephoto camera is another feature that sets the iPhone 18 Pro apart. According to current expectations, the iPhone 18 Pro and Pro Max will remain the only models in the lineup with a dedicated telephoto lens. The iPhone Ultra is expected to offer main and ultra-wide cameras, but no telephoto for optical zoom.

A dedicated telephoto lens is critical for high-quality zoom shots. Without it, the phone has to rely on digital cropping or sensor cropping, which often results in softer images. Apple is also rumored to be improving the telephoto camera this year with a larger aperture, which would improve low-light performance and depth-of-field control. That would make the Pro models even more attractive to photographers.

The absence of a telephoto lens on the iPhone Ultra is a surprising trade-off for a premium flagship. Many competing foldable phones include multiple zoom lenses, but Apple's focus on thinness may have forced the company to simplify the Ultra's rear camera. For anyone who wants the most versatile camera system, the iPhone 18 Pro is expected to be the clear winner.

Bonus: Traditional iPhone experience

This last item is not a hardware specification, but it could matter just as much. The iPhone 18 Pro will offer a familiar, traditional iPhone experience. It has a single display that works the same way every time, with the same button layout, the same gesture navigation, and the same iOS interface that iPhone owners already know.

The iPhone Ultra will be something different. Its outer and inner displays have different sizes and shapes, and using it requires folding and unfolding. Some people will love the flexibility of a compact phone that opens into a tablet, but adapting to the new mechanics could take time. The foldable design also raises questions about durability, screen creases, and long-term reliability, even if Apple's execution is polished.

For the average consumer, familiarity is a feature. The iPhone's rectangular slab design has remained essentially unchanged for years, and that consistency has built trust. The Ultra might appeal to early adopters and enthusiasts, but the iPhone 18 Pro is likely to be the more comfortable, straightforward choice for the majority of buyers.

Which upcoming iPhone are you thinking about buying this fall? The answer will depend on whether you prioritize camera hardware, battery life, biometrics, or the novelty of a foldable design. What is clear is that the iPhone 18 Pro does not have to be the cheapest model to be the most practical one.
