Introduction
Xiaomi has officially entered a new chapter in its foldable smartphone lineup with the Xiaomi 18 Fold.
The new flagship combines a wide passport-style foldable design with Xiaomi’s own 3nm XRING O3 chipset. It also brings dual 120Hz LTPO AMOLED displays, a Leica-backed 200MP triple-camera system, and a large 6,000mAh battery.
More importantly, the Xiaomi 18 Fold is the first Xiaomi flagship to feature the company’s new XRING O3 processor. The phone launched in China on September 7, 2026, with sales beginning later in the month.
So, what makes this foldable different? Let’s look at its design, display, performance, cameras, battery, price, and availability.
Xiaomi 18 Fold Overview
What is it?
The Xiaomi 18 Fold is Xiaomi’s latest book-style foldable smartphone. Unlike traditional tall foldables, it uses a shorter and wider design.
When folded, it offers a 5.38-inch cover display. Open it up, and you get a large 7.58-inch inner display.
Both screens support LTPO technology and refresh rates up to 120Hz. They can also reach up to 4,000 nits of peak brightness.
Who is it for?
The phone targets users who want a premium smartphone for:
- Multitasking
- Gaming
- Content consumption
- Mobile photography
- Productivity
- Large-screen work on the go
Why does it matter?
The XRING O3 is the biggest story here.
Xiaomi developed the chip in-house using a 3nm process. It features a 10-core CPU and 16-core GPU, while Xiaomi claims significant performance improvements over its previous XRING O1 platform.

Design & Build Quality
The Xiaomi 18 Fold takes a different approach to foldable design.
Instead of a very tall and narrow shape, Xiaomi has created a shorter and wider passport-style body. This gives both the outer and inner screens a wider aspect ratio.
When unfolded, the phone measures just 5.02mm thick and weighs around 219 grams. Folded, it measures 10.68mm thick.
Furthermore, Xiaomi uses a 7-series aluminum alloy frame and its Dragon Bone hinge design.
The inner display uses a dual-layer ultra-thin glass structure. Xiaomi also says the hinge went through extensive structural optimization and durability testing.
The phone comes in Black, Nishino Red, and Warm Gold White. A limited Ceramic Special Edition is also available.
Display
The Xiaomi 18 Fold features two large LTPO AMOLED displays.
The outer screen measures 5.38 inches, while the unfolded inner screen measures 7.58 inches.
Both displays support up to a 120Hz refresh rate. Therefore, scrolling, animations, gaming, and multitasking should feel smooth.
The displays can also reach up to 4,000 nits peak brightness, which should help with outdoor visibility.
Cover Display
- 5.38-inch LTPO AMOLED
- 1712 × 1168 resolution
- 1–120Hz refresh rate
- Up to 4,000 nits
- Wide passport-style aspect ratio
Inner Display
- 7.58-inch flexible LTPO AMOLED
- 2364 × 1672 resolution
- 1–120Hz refresh rate
- Up to 4,000 nits
- Large workspace for multitasking
Moreover, HyperOS 4 takes advantage of the wider display by supporting split-screen and multi-app layouts.
Performance
The biggest hardware change comes from the XRING O3.
XRING O3 Chipset
The XRING O3 uses a 3nm manufacturing process and features:
- 10-core CPU
- 16-core G2-Ultra NX GPU
- Dedicated NPU
- LPDDR6 RAM on the 1TB configuration
Xiaomi claims the XRING O3 improves CPU, GPU, NPU, and memory performance compared with the previous XRING O1. The company also claims up to a 60% multi-core CPU improvement and up to an 85% GPU performance improvement over its predecessor.
Multitasking
The wide inner screen gives the Xiaomi 18 Fold plenty of room for multitasking.
For example, HyperOS 4 can support multiple apps simultaneously, including split-screen and three-panel layouts. Some configurations can even manage six apps across the wider display.
Gaming
The XRING O3 is designed for flagship-level performance. In addition, its G2-Ultra NX GPU introduces advanced graphics capabilities for supported games.
As a result, the phone should be well suited to demanding mobile games and graphics-heavy applications.
Overall Responsiveness
With up to 16GB RAM, fast UFS 4.1 storage, a 120Hz LTPO display, and the XRING O3, the Xiaomi 18 Fold is positioned as a high-performance foldable.
However, real-world performance can vary depending on software optimization, thermals, and individual workloads.
Camera
Photography is another major highlight.
The Xiaomi 18 Fold features a Leica-backed triple rear camera system.
Rear Camera Setup
- 200MP primary camera
- 50MP periscope telephoto
- 50MP ultra-wide camera
The 200MP main camera uses a 1/1.56-inch-type sensor and includes optical image stabilization.
Meanwhile, the periscope camera provides 3.5x optical zoom. It also supports higher levels of zoom using lossless and AI-assisted processing.
The setup gives the phone a flexible focal range for:
- Portrait photography
- Landscape shots
- Street photography
- Zoom photography
- Everyday photos
For selfies and video calls, the phone includes dual 16MP front cameras, with one camera placed on each display.
Battery Life
Despite its thin foldable body, Xiaomi has packed a 6,000mAh battery inside.
That is a notable capacity for a foldable smartphone, especially considering the large inner display.
The battery supports:
- 67W wired fast charging
- 50W wireless charging
Therefore, users who spend long hours watching videos, gaming, multitasking, or browsing on the inner display should have a sizeable battery reserve.
Actual battery life, however, will depend on display brightness, refresh rate, network usage, gaming, and software settings.
Software & AI
The Xiaomi 18 Fold runs HyperOS 4 based on Android 17.
The software has been optimized for the foldable screen. As a result, users can take advantage of multi-window layouts and multiple apps at once.
The XRING O3 also includes a dedicated NPU for AI workloads.
However, the availability of certain AI features can vary by region and software version.
Connectivity
The Xiaomi 18 Fold includes modern connectivity options such as:
- 5G
- Wi-Fi 7
- Bluetooth 6.0
- NFC
- USB Type-C
- Dual Nano-SIM
A side-mounted fingerprint sensor handles biometric security. Face unlock is also supported.
Durability
Foldable phones have traditionally faced durability concerns. Xiaomi has therefore focused heavily on the hinge and display structure.
The Xiaomi 18 Fold features a dual-layer ultra-thin glass structure for the inner display. It also uses a reinforced aluminum frame.
Furthermore, published specifications list IP58 and IP59 protection.
Still, users should remember that foldable displays remain more delicate than conventional smartphone screens.

The other configurations are priced as follows:

Availability in Nepal
The Xiaomi 18 Fold is currently confirmed for the Chinese market.
As of September 24, 2026, Xiaomi has not announced official global availability for the device. In addition, Xiaomi’s previous Mix Fold models have generally remained limited to China.
Therefore, there is currently no official Xiaomi 18 Fold price or launch date for Nepal.
If Xiaomi eventually brings the phone to Nepal, the final retail price could be higher than the converted Chinese price because of taxes, distribution costs, warranty coverage, and local pricing.
