The foldable smartphone market is becoming more competitive than ever. In 2026, two of the most interesting devices in this category are the Apple iPhone Duo and the Xiaomi 18 Fold. Both smartphones use a book-style folding design, offering a regular phone experience when closed and a larger tablet-like display when opened.

However, Apple and Xiaomi have taken very different approaches.

The iPhone Duo focuses on Apple's premium ecosystem, software experience, powerful A20 Pro processor and a polished foldable design. Xiaomi, on the other hand, is targeting users who want impressive hardware specifications, a large battery, fast charging and an advanced Leica camera system.

So, which foldable phone is better for Indian buyers?

In this detailed gadget review, we compare the Apple iPhone Duo and Xiaomi 18 Fold based on design, displays, cameras, performance, battery, software, price and overall value.

Apple iPhone Duo vs Xiaomi 18 Fold: Quick Answer

If you want Apple's ecosystem, iOS, premium software experience and long-term integration with other Apple products, the iPhone Duo is the more attractive option.

If you want a larger battery, faster charging, more versatile cameras and strong hardware specifications, the Xiaomi 18 Fold looks more appealing.

However, there is an important difference for Indian buyers: Apple's foldable is officially positioned as a premium Indian-market product, while Xiaomi's 18 Fold has initially been launched in China, with international availability still a major consideration.

Apple iPhone Duo Price in India

The Apple iPhone Duo is Apple's first foldable iPhone and sits at the very top of the company's smartphone lineup.

In India, the iPhone Duo starts at ₹2,99,900 for the 256GB variant. Higher-storage versions are available as well, with the top-end model reaching more than ₹4 lakh.

iPhone Duo Storage Options

The available storage configurations include:

• 256GB

• 512GB

• 1TB

• 2TB

The starting price itself makes the iPhone Duo a luxury smartphone rather than a mainstream purchase.

For most users, the 256GB model should provide plenty of storage. However, professionals who record large amounts of high-resolution video may find the 1TB or 2TB versions useful.

Xiaomi 18 Fold Price and Availability

The Xiaomi 18 Fold takes a different approach to pricing.

The phone starts at CNY 10,999 in China, which translates to roughly ₹1.5 lakh before considering taxes, import costs and any potential Indian-market pricing. The phone has initially been launched in China, so Indian buyers should not treat the converted Chinese price as an official India price.

This creates an interesting situation.

On paper, Xiaomi's foldable appears considerably cheaper than Apple's iPhone Duo. However, actual Indian pricing will depend on whether Xiaomi officially launches the device in India.

Therefore, buyers interested in the Xiaomi 18 Fold should carefully check official availability before making a purchase decision.

Design: Two Foldables With a Similar Concept

Both phones use a passport-style book-folding design.

When closed, they work like conventional smartphones. When opened, they provide a much larger display for multitasking, gaming, video watching and productivity.

The Xiaomi 18 Fold has a 5.38-inch outer display and a 7.58-inch internal display. Its design is relatively wide, making the unfolded screen particularly useful for multimedia and multitasking.

The iPhone Duo features a similarly compact outer screen and approximately 7.6-inch folding display.

However, weight is one area where Xiaomi has an advantage.

The Xiaomi 18 Fold weighs around 219 grams, while the iPhone Duo is reported at approximately 254 grams.

That difference may seem small on paper, but it can become noticeable when carrying the phone throughout the day.

Display: Big Screens for Work and Entertainment

Foldable smartphones are mainly attractive because they provide more screen space without requiring users to carry a tablet.

The Xiaomi 18 Fold features a 7.58-inch internal OLED display with a 120Hz refresh rate. The outer display measures approximately 5.38 inches and also uses a high-refresh-rate OLED panel.

The internal display is especially useful for:

• Watching movies

• Reading documents

• Gaming

• Editing photos

• Multitasking

• Browsing websites

• Running multiple applications

The iPhone Duo also offers a roughly 7.6-inch internal display, putting it directly against Xiaomi in terms of screen size.

For people who want a foldable mainly for entertainment and productivity, both devices offer a significant advantage over traditional smartphones.

Performance: Apple A20 Pro vs Xiaomi XRing O3

Performance is another major difference between these phones.

The iPhone Duo is powered by Apple's A20 Pro chip, designed to deliver flagship performance and support Apple's latest AI and software features.

Apple's advantage comes from its tight integration between hardware and software. iOS is specifically optimised for Apple's processors, allowing the company to control both sides of the smartphone experience.

Xiaomi takes a different approach with its XRing O3 processor.

The Xiaomi 18 Fold uses a 3nm XRing O3 chipset and offers configurations with up to 16GB RAM.

The high RAM capacity gives Xiaomi plenty of room for multitasking.

For everyday activities, both devices should offer excellent performance. However, users who prefer iOS and Apple's ecosystem may find the iPhone Duo more attractive, while Android enthusiasts may prefer Xiaomi's flexibility.

Camera Comparison

Camera performance is one of the most interesting differences between these foldables.

The Xiaomi 18 Fold features a Leica-powered triple-camera system.

Its camera setup includes:

• 200MP main camera

• 50MP ultra-wide camera

• 50MP telephoto camera

• 3.5x optical zoom

The 200MP primary camera is one of the phone's biggest selling points. The dedicated telephoto camera also provides greater flexibility for portraits and distant subjects.

Apple takes a different approach.

The iPhone Duo features a dual 48MP rear camera system, consisting of a main camera and ultra-wide camera.

Although Xiaomi appears stronger when looking purely at camera specifications, megapixels do not automatically determine image quality.

Apple has traditionally focused heavily on computational photography, colour processing, video quality and consistency.

Therefore, Xiaomi may appeal more to users who want maximum camera hardware, while Apple may attract users who prioritise an easy and consistent photo-and-video experience.

Battery and Charging

This is another area where Xiaomi has a clear hardware advantage.

The Xiaomi 18 Fold comes with a large 6,000mAh silicon-carbon battery and supports 67W wired charging and 50W wireless charging.

A large battery is particularly important for foldable smartphones because the bigger internal screen can consume more power.

Apple's iPhone Duo takes a different approach, focusing more heavily on power efficiency and software optimisation.

For users who prioritise fast charging and a large battery, Xiaomi has the more impressive specification sheet.

For users who prefer Apple's integrated hardware and software approach, the iPhone Duo remains appealing.

Software Experience

Software could ultimately be one of the biggest reasons to choose one phone over the other.

The iPhone Duo runs Apple's latest iOS experience and benefits from Apple's ecosystem.

If you already own:

• MacBook

• iPad

• Apple Watch

• AirPods

the iPhone Duo can integrate naturally with your existing devices.

Xiaomi 18 Fold runs HyperOS, giving users the flexibility of Android and Xiaomi's multitasking features.

For people who regularly customise their phones and prefer Android's flexibility, Xiaomi may be the better choice.

Multitasking: Where Foldables Really Matter

The biggest reason to purchase a foldable phone is not simply having a larger display.

It is the ability to do more at the same time.

A large internal display can make it easier to:

• Reply to messages while browsing

• Watch videos while taking notes

• Compare products

• Read documents

• Work with spreadsheets

• Browse multiple websites

• Use multiple applications

Xiaomi's 18 Fold is particularly interesting for productivity because its wider internal display is designed around multitasking.

This is where foldable phones can provide a genuine advantage over conventional smartphones.

Apple iPhone Duo vs Xiaomi 18 Fold: Key Differences

Specifications can vary by market and final retail configuration.

Which Foldable Is Better for Indian Buyers?

There is no single answer because the two devices target different audiences.

Choose iPhone Duo If:

• You already use Apple products.

• You prefer iOS.

• You want Apple's first foldable iPhone.

• Camera and video consistency are important.

• You want long-term Apple ecosystem integration.

• Budget is not your biggest concern.

Choose Xiaomi 18 Fold If:

• You prefer Android.

• You want a large battery.

• Fast charging is important.

• You want a 200MP camera.

• You want a dedicated telephoto camera.

• You want more RAM.

• You prefer a lighter foldable design.

However, Indian consumers should pay close attention to official availability before considering the Xiaomi model.

Is the iPhone Duo Worth Its Premium Price?

At ₹2,99,900, the iPhone Duo is certainly not an affordable smartphone.

The price places it in a luxury category where buyers are paying not only for specifications but also for Apple's ecosystem, design, software and first-generation foldable technology.

The Xiaomi 18 Fold looks more aggressive from a hardware-value perspective, particularly with its 6,000mAh battery, 200MP camera and 67W charging.

However, Apple's appeal lies in its ecosystem and software experience.

Therefore, the iPhone Duo is worth considering if you specifically want Apple's foldable experience and have the budget for it.

Final Verdict

The Apple iPhone Duo and Xiaomi 18 Fold represent two very different visions of the premium foldable smartphone.

The iPhone Duo focuses on Apple's ecosystem, iOS, premium design and flagship performance. Xiaomi takes a more hardware-focused approach with a 200MP Leica camera, 6,000mAh battery, fast charging and up to 16GB RAM.

For Indian buyers, the iPhone Duo has the advantage of official Indian pricing and Apple's established ecosystem. Xiaomi's 18 Fold is extremely interesting from a specification and value perspective, but availability in India remains an important consideration.

Our verdict: Choose the iPhone Duo if you want Apple's ecosystem and premium foldable experience. Choose the Xiaomi 18 Fold if hardware specifications, camera versatility, battery capacity and charging speed are your top priorities.
