Xiaomi may be making one of its boldest flagship decisions in years. According to recent supply chain leaks and industry insiders, the company has reportedly halted development of the Xiaomi 18 Ultra as a traditional slab smartphone. Instead, the cutting-edge hardware originally planned for the device could debut in the upcoming Xiaomi Mix Fold 5.
If the reports are accurate, Xiaomi isn’t abandoning its flagship ambitions. Rather, it’s choosing to make its next foldable the true showcase for its latest innovations.
Why Xiaomi May Have Dropped the 18 Ultra
For months, rumors suggested that the Xiaomi 18 Ultra would arrive as the company’s most advanced camera phone yet. However, newer reports indicate that rising component costs forced Xiaomi to rethink its strategy.
High-end memory, premium camera hardware, and next-generation components have become significantly more expensive, making it increasingly difficult to build an Ultra device without pushing the retail price into uncomfortable territory.
Instead of releasing a flagship that compromises on features—or one that becomes too expensive for most buyers—Xiaomi is said to have paused the project entirely.
Some reports suggest that certain ideas from the canceled device could eventually appear in another premium model, possibly under a different name. However, the company’s immediate focus now appears to be the Mix Fold lineup.
The Mix Fold 5 Could Become Xiaomi's True Flagship
Foldable phones have improved rapidly over the past few years, but many still make sacrifices in areas such as camera quality, battery capacity, or sustained performance.
That could change with the Mix Fold 5.
Rather than treating the foldable as a secondary flagship, Xiaomi reportedly plans to equip it with hardware originally developed for the 18 Ultra, potentially creating one of the most capable foldable smartphones ever released.
A 200MP Main Camera
Perhaps the biggest upgrade is the rumored 200-megapixel primary camera.
If accurate, this would place the Mix Fold 5 among the few foldables capable of competing directly with traditional Ultra flagships in photography. A larger, high-resolution sensor could deliver sharper images, better dynamic range, and stronger low-light performance while offering greater flexibility for digital zoom.
For years, foldable phones have lagged behind standard flagship devices in camera quality. Xiaomi may finally be looking to change that.
A Massive 6,000mAh Battery
Battery life has long been one of the biggest challenges for foldable devices because of their thin designs and dual-display construction.
Leaks suggest the Mix Fold 5 could feature a battery approaching 6,000mAh, which would be remarkable for a foldable smartphone.
If Xiaomi manages to fit such a large battery without making the device significantly thicker, it could set a new benchmark for endurance in the foldable segment.
Xiaomi's Custom XRing O3 Chip Could Take Center Stage
Another major highlight is the expected debut of Xiaomi’s next-generation in-house processor, the XRing O3.
The chip is rumored to be manufactured using TSMC’s advanced 3nm process, offering notable improvements in both performance and power efficiency.
Early reports also point to a redesigned CPU architecture aimed at delivering stronger sustained performance while keeping temperatures under control—an especially important factor for foldable devices, where thermal management is often more challenging than on conventional smartphones.
If these claims prove accurate, the XRing O3 could become Xiaomi’s most ambitious custom chipset to date and further reduce the company’s dependence on third-party silicon.
A Shift in Xiaomi's Flagship Strategy
Rather than launching separate flagship slab and foldable phones with different priorities, Xiaomi may be consolidating its best technologies into a single premium device.
That would represent a significant change in strategy.
Instead of asking consumers to choose between the best camera phone and the best foldable, Xiaomi could be aiming to deliver both in one package. If successful, the Mix Fold 5 would stand out not only against competing foldables but also against premium flagships from other manufacturers.
What This Means for Buyers
Nothing has been officially confirmed by Xiaomi, so these reports should be treated as rumors until the company announces its future plans.
However, if the leaks accurately reflect Xiaomi’s direction, the cancellation of the 18 Ultra may not be bad news after all. Instead, it could signal the beginning of a new flagship era where foldable phones receive the company’s most advanced camera system, biggest battery, and newest processor.
The Mix Fold 5 could end up being far more than Xiaomi’s next foldable. It may become the company’s most ambitious smartphone yet—and one of the most powerful premium devices of 2026.
