## Key points

- Xiaomi's 18 Fold is a short, wide book-style foldable unveiled at IFA
- Features Xiaomi's own Xring O3 chip and triple 200MP Leica camera
- Bigger battery and brighter screens than Samsung's Galaxy Z Fold 8, but no IP rating

## Summary

Xiaomi has unveiled the 18 Fold, a book-style foldable phone with an unusually short, wide form factor, previewed by The Verge at IFA ahead of Apple's own rumoured foldable launch this week. It is Xiaomi's first book-style foldable since 2024's Mix Fold 4 and follows Huawei and Samsung in adopting a squatter design, but goes further still: its roughly 1.4:1 aspect ratio, shared by both the 7.58-inch inner and 5.38-inch outer screens, closely matches standard paper sizes and IMAX cinema proportions. Compared with Samsung's Galaxy Z Fold 8, it is pocketable and comfortable to use one-handed when closed, though it is somewhat heavier, thicker, has no stated IP water-resistance rating, and shows a more visible hinge crease; Oppo's Find N6 remains the benchmark for minimising the fold crease.

The phone debuts Xiaomi's own Xring O3 chipset, said to match Qualcomm's Snapdragon 8 Elite, paired with Arm's new Mali G2-Ultra NX GPU offering DLSS-style graphics acceleration on Android. It packs a 6,000mAh silicon-carbon battery (versus 4,800mAh in the Z Fold 8) with 67W wired and 50W wireless charging, OLED screens reaching 4,000 nits, and a Leica-branded triple rear camera comprising a 200-megapixel main sensor, a 50-megapixel 3.5x periscope telephoto and a 50-megapixel ultrawide. It comes in black, white and red, plus a limited pink ceramic edition capped at 1,500 units.
