Xiaomi 18 Fold steps out at IFA 2026 with in-house XRing O3 chip ahead of Apple's big reveal
Xiaomi has put its next foldable on public display, and the Xiaomi 18 Fold doubles as the launch vehicle for the company's own silicon. The phone appeared at IFA 2026 in Berlin this week in a cherry red finish, and it goes on sale in China on September 7, two days before Apple's September 9 event, where the iPhone maker's first foldable is expected to be revealed.
The foldable keeps the short-and-wide "passport" proportions now common in the category, pairing a 5.38-inch cover screen with a 7.58-inch inner display. The rear camera is a triple setup with Leica imaging, and memory duties fall to ChangXin Memory Technologies (CXMT), the Chinese DRAM maker, which supplies next-generation chips. Attendees could inspect the device under glass at the show, but no hands-on access was offered.
At the center sits the XRing O3, the second generation of Xiaomi's in-house processors and the successor to last year's XRing O1. The 3nm chip supports LPDDR6 memory, and Xiaomi positions it as the silicon that will run AI across its wider ecosystem. Xiaomi first previewed the processor during its HyperOS 4 launch event before the IFA appearance.
Why the XRing O3 makes the Xiaomi 18 Fold different
The silicon is the centerpiece of this launch. Xiaomi's recent flagships have run on Qualcomm Snapdragon processors, and the 18 Fold is the first handset in its top line to remove that dependence. Designing the chip in-house gives Xiaomi control of its own roadmap for memory, power management, and AI features, which is why LPDDR6 support reaches a Xiaomi phone before most rivals. It is the same integration strategy Apple applies to its A-series silicon, now pointed at a foldable.
The naming change signals the same break with the past. Earlier Xiaomi foldables carried the Mix Fold label; this model adopts the Xiaomi 18 designation of the current flagship series, tying the foldable's identity to the arrival of the company's own processor.
Two days ahead of Apple
Xiaomi's mobile division president, Lu Weibing, confirmed the September 7 launch date on Weibo. The calendar places the foldable in stores 48 hours before Apple's September 9 event in Cupertino, where a foldable iPhone, discussed under the names iPhone Fold or iPhone Ultra, is widely anticipated. Xiaomi has so far confirmed the Xiaomi 18 Fold only for China, with no international release schedule attached.
That makes the Berlin debut notable: a China-only phone rarely gets a prominent European preview. Xiaomi used IFA to present the device as part of a display covering more than 380 products, pairing the foldable with the Xiaomi Pad 9 Pro Max, a tablet that runs on the same XRing O3 chip and launches alongside it on September 7.
Why this matters
The Xiaomi 18 Fold gives foldable buyers a flagship option built on a homegrown 3nm processor, and it lands in stores ahead of Apple's anticipated entry into the category. The September 7 launch leaves Xiaomi two clear days to own the foldable conversation before the iPhone maker responds. The reception of the XRing O3 in reviews and early sales will set the pace for how quickly the company's custom silicon spreads beyond the Fold and the Pad.
