Performance is another important factor in this comparison. Both smartphones use custom flagship processors instead of relying on conventional chipsets.
The Apple iPhone Duo runs on the A20 Pro processor. It uses a 2nm manufacturing process and features a six-core CPU with a seven-core GPU. The phone also comes with 12GB RAM and 256GB starting storage.

Apple iPhone Duo vs Xiaomi 18 Fold: Camera
The Apple iPhone Duo features a dual rear camera setup with:
- 48MP primary camera with sensor-shift OIS
- 48MP ultra-wide camera
The primary camera supports detailed photographs and optical-quality zoom options. The ultra-wide camera offers a 120-degree field of view for landscape and group photography.
Apple also offers several photography features, including Smart HDR, Night Mode, Portrait Mode and Photographic Styles. Its video recording capabilities include 4K Dolby Vision recording at up to 120fps on the main camera.
Camera performance is where Xiaomi has a clear hardware advantage. The 18 Fold features a triple rear camera setup, while Apple offers two rear cameras.
The Xiaomi 18 Fold includes:
- 200MP primary camera with OIS
- 50MP telephoto camera with optical zoom
- 50MP ultra-wide camera
The 200MP primary camera should capture detailed photographs in different lighting conditions. The dedicated telephoto camera also makes it easier to capture distant subjects without relying entirely on digital zoom.
Its 50MP ultra-wide camera is useful for landscape photography, group pictures and wider shots. Xiaomi also lists Leica camera features for the device.
For selfies and video calls, the iPhone Duo has a 12MP front camera. Xiaomi offers a 16MP front camera, along with an additional 16MP cover camera according to comparison listings.
Which has the better camera?
On paper, the Xiaomi 18 Fold offers more camera flexibility. Its 200MP primary sensor and dedicated telephoto lens give it an advantage for zoom photography. However, Apple's image processing and video recording features make the iPhone Duo a strong option for content creators.
Apple iPhone Duo vs Xiaomi 18 Fold: Battery And Charging
Battery capacity is another area where Xiaomi takes the lead.
The Xiaomi 18 Fold packs a 6,000mAh silicon-carbon battery. It supports 67W wired charging and 50W wireless charging. The larger battery should help the phone handle long hours of browsing, gaming, video streaming and multitasking.
Apple's iPhone Duo has a reported battery capacity of 4,883mAh. It supports fast wired charging and MagSafe wireless charging at up to 25W. Apple's power-efficient A20 Pro processor and iOS optimisation should also help manage battery consumption.
However, Xiaomi offers a higher battery capacity and faster wireless charging on paper.
Which phone offers better battery life?
The Xiaomi 18 Fold looks like the better option for users who prioritise battery capacity and charging speed. The iPhone Duo may still deliver good battery life through hardware and software optimisation, but real-world battery tests are needed for a fair comparison.
Apple iPhone Duo vs Xiaomi 18 Fold: Software And Updates
Software plays an important role in the foldable experience. Both companies have developed their interfaces to make better use of the larger inner screens.
The Apple iPhone Duo runs on iOS 27. Apple has introduced foldable-specific software features to improve multitasking and app navigation. Its interface also offers a taskbar and improved controls for using multiple applications.
The iPhone Duo should appeal to users who already own Apple products. Features such as AirDrop, iCloud, Apple Intelligence and seamless connectivity across Apple devices make the ecosystem more convenient.
The Xiaomi 18 Fold runs on Android 17 with HyperOS 4. It offers Android-based customisation, multitasking features and Xiaomi's software tools.
However, regional availability is an important concern. The Xiaomi 18 Fold has been reported as a China-exclusive model, and its Chinese software version may not include Google Play Store and Google services out of the box. This could create problems for Indian users who depend on Google apps and services.
Apple also has an advantage in its published software support commitment, with comparison listings indicating up to seven years of updates.
Which software is better?
The iPhone Duo is the safer choice for users who want a familiar global software experience and long-term support. Xiaomi offers more Android customisation, but buyers should check Google services, notification support and regional compatibility before purchasing an imported unit.
Apple iPhone Duo vs Xiaomi 18 Fold: Price In India
Price is one of the biggest differences between these two foldable smartphones.
The Xiaomi 18 Fold is listed at ₹1,69,999 in India. The Apple iPhone Duo is listed at ₹2,99,900.
This creates a price difference of approximately ₹1,29,901. Xiaomi offers a significantly lower listed price while providing a larger battery and a more versatile rear camera setup.
However, buyers should consider availability before making a decision. Reports indicate that the Xiaomi 18 Fold is currently limited to China. Therefore, its listed Indian price should not be treated as confirmation of an official India launch or local warranty.
The iPhone Duo has a much higher price, but it offers Apple's software ecosystem, global availability and IP68 protection.

Apple iPhone Duo vs Xiaomi 18 Fold: Which One Should You Buy?
Both foldable smartphones offer impressive specifications, but they target slightly different buyers.
The Apple iPhone Duo is a better choice for users who prefer iOS, premium build quality and a well-integrated software experience. Its high-resolution OLED display, A20 Pro processor and IP68 protection make it a strong premium foldable.
The Xiaomi 18 Fold, on the other hand, offers better hardware value on paper. Its 200MP triple camera, 6,000mAh battery, faster charging and lighter design make it an interesting option for photography enthusiasts and heavy users.
However, software and availability remain important concerns. Its China-focused software experience may not suit Indian buyers who rely on Google services.
Our verdict: The Xiaomi 18 Fold offers better specifications for the price, but the Apple iPhone Duo is the more practical choice for Indian buyers looking for a reliable global foldable experience. If Xiaomi launches an official Indian variant with full Google support and local warranty, it could become a much stronger competitor.
