Xiaomi’s next-generation large-screen foldable smartphone is once again attracting attention. Recent leaks suggest that the Xiaomi MIX Fold 5 could return with a comprehensive hardware and software upgrade, potentially featuring Xiaomi’s next-generation self-developed flagship chipset, XRing O3, alongside HyperOS 4 and Android 17.
The MIX Fold 5 would also mark an important return for Xiaomi’s large foldable lineup. The company launched the MIX Fold 4 in July 2024, but did not follow it with another large foldable in 2025. If the latest reports are accurate, Xiaomi could be preparing to re-enter the segment after a two-year gap with a substantially redesigned device rather than a conventional annual refresh.
HyperOS 4 and Android 17
One of the most interesting details in the latest leak comes from a suspected MIX Fold 5 system screenshot.
The device reportedly appears under the codename “lhasa”, while the software version begins with 4.0 and the Android version is listed as Android 17.
If the leaked images and device information are genuine, this would suggest that Xiaomi is already testing its next-generation operating system on the new foldable.
For a large foldable device, software optimization is particularly important. Unlike conventional smartphones, foldables need to support seamless transitions between the external and internal displays, as well as split-screen layouts, multi-window applications, landscape interfaces and more sophisticated background resource management.
HyperOS 4 could therefore play a major role in the MIX Fold 5’s user experience. Features such as AI-powered note taking, cross-application workflows, file management and cross-device collaboration can potentially benefit significantly from the larger unfolded display.
The leaked system information does not confirm the final software experience, but it provides an indication that Xiaomi is testing Android 17-based HyperOS 4 on the foldable platform.
XRing O3 Could Be the MIX Fold 5’s Biggest Highlight
The chipset is expected to be one of the defining features of the MIX Fold 5.
Previous reports have claimed that Xiaomi could equip the device with its next-generation self-developed flagship processor, XRing O3. The chip is reportedly expected to continue using a 3nm manufacturing process, although Xiaomi has yet to officially disclose its specifications.
Details such as CPU architecture, maximum clock speeds, GPU configuration, ISP capabilities and NPU performance remain unknown.
Xiaomi’s first-generation XRing O1 already demonstrated the company’s ambition to develop its own flagship smartphone silicon. The chip was reportedly manufactured using a 3nm process and featured approximately 190 billion transistors, a 10-core CPU and a 16-core GPU. It has also been used in smartphone and tablet products.
If XRing O3 continues to use a 3nm process, the manufacturing node itself may not be the most important upgrade. Instead, improvements to CPU architecture, GPU efficiency, image processing, AI acceleration, memory architecture, cache design and power management could have a greater impact on real-world performance.
A More Challenging Test for Xiaomi’s Chip
Using a next-generation self-developed chipset in a large foldable could provide a more demanding test of Xiaomi’s engineering capabilities than deploying it in a conventional smartphone.
Foldable devices have significantly more complicated internal structures. The hinge, dual displays, multiple cameras and other components compete for limited internal space, while thermal management becomes more challenging.
The power requirements also differ depending on whether the device is folded or fully opened. An unfolded large display can consume considerably more power during gaming, video playback and multitasking.
As a result, if the MIX Fold 5 does eventually launch with XRing O3, the device could serve as an important showcase for the integration of Xiaomi’s chipset, operating system, display and thermal-management technologies.
6,000mAh Battery and 200MP Camera
The rumored hardware upgrades reportedly extend beyond the processor.
The MIX Fold 5 is expected to feature a battery of around 6,000mAh, representing a substantial increase over the 5,100mAh battery used by the MIX Fold 4.
That would represent an increase of roughly 18%. For a large foldable, the additional capacity could be particularly useful because the internal display provides a larger canvas for multitasking, gaming and productivity but also places greater demands on the battery.
The device is also rumored to retain wireless charging, which would help maintain its positioning as a premium flagship.
Photography could receive a major upgrade as well. Reports suggest that the MIX Fold 5 may feature a 200MP main camera.
Historically, foldable phones have sometimes sacrificed camera hardware in order to manage thickness, weight and internal space. A higher-resolution sensor on the MIX Fold 5 would indicate that Xiaomi is attempting to position the device as a more complete flagship rather than treating the camera system as a secondary feature.
New Hinge and Improved Durability
The hinge will be another crucial component of the MIX Fold 5.
Current reports point to a new-generation self-developed hinge, together with a higher level of water resistance.
For foldable smartphones, hinge engineering can have a greater impact on long-term usability than small differences in benchmark performance. The hinge affects the device’s thickness, folding mechanism, durability and resistance to everyday wear.
A more advanced hinge could allow Xiaomi to improve structural reliability while potentially creating additional internal space for the battery and other components.
Possible New Design
The latest information about the exterior design remains limited, but some reports suggest that Xiaomi may adopt a more horizontally oriented screen ratio.
The rear camera module could also reportedly move toward a horizontal arrangement.
Such changes would make sense if Xiaomi is substantially redesigning the MIX Fold 5 rather than simply carrying forward the MIX Fold 4’s structural design.
After skipping a generation, Xiaomi has an opportunity to rethink the internal component arrangement, hinge structure and body proportions of its large foldable platform.
Potential Price Above RMB 10,000
Pricing is another area attracting attention.
Current market rumors suggest that the MIX Fold 5 could start at more than RMB 10,000, significantly above the MIX Fold 4’s original starting price of RMB 8,999.
A higher price could potentially be justified if the new device combines XRing O3, a 6,000mAh-class battery, 200MP imaging, HyperOS 4, wireless charging and a redesigned folding mechanism.
However, Xiaomi would face a clear challenge: the MIX Fold 5 would need to offer enough visible improvements to justify the higher cost in an increasingly competitive foldable market.

A Major Test for Xiaomi’s Foldable Strategy
The MIX Fold 5 could be more important to Xiaomi than an ordinary annual flagship upgrade.
After the MIX Fold 4 launched in 2024, the company’s absence from the large-screen foldable segment created a significant gap in its product cycle. Returning with a device built around XRing O3, HyperOS 4, Android 17, a larger battery, upgraded imaging and a new hinge design would allow Xiaomi to demonstrate how its hardware and software ecosystem has evolved during that period.
More importantly, the MIX Fold 5 could become a showcase for Xiaomi’s broader self-developed technology strategy. Rather than focusing on a single specification, the company appears to be pursuing closer integration between its chipset, operating system, AI capabilities and hardware design.
At this stage, however, the MIX Fold 5 name, launch date, XRing O3 specifications and final hardware configuration have not been officially confirmed by Xiaomi. The reported specifications should therefore be treated as rumors until the company provides official information.
If the current leak cycle continues, the next major detail to watch will be the official specifications and performance of XRing O3. Its capabilities inside a large foldable chassis could ultimately determine whether the MIX Fold 5 becomes a meaningful comeback for Xiaomi in the premium foldable market.
