Foldable Kings Battle: Apple Enters the Ring
Apple’s first foldable, the iPhone Duo, shook up the market, but three Android rivals are already there:
- Galaxy Z Fold8 (Samsung): the most mature, and the lightest book-style foldable.
- Mate XT 2 (Huawei): a tri-fold flagship, among the most innovative designs around.
- Xiaomi 18 Fold: the self-developed Xring chip and aggressive specs.
Creases and feel matter, but the chip matters too.
⚠️ Pricing note: Apple has not announced iPhone Duo pricing, and Huawei and Xiaomi have published no official USD prices, so CNY is listed as-is.
Specs Comparison: The Four Contenders
| Specification | iPhone Duo | Z Fold8 | Mate XT 2 | Xiaomi 18 Fold |
|---|---|---|---|---|
| Starting Price | ⚠️ Not announced | US$1,899.99 | ¥19,999 | ¥10,999 |
| Weight | 254 g | 201 g (lightest) | ~297 g (heaviest tri-fold) | ~250 g |
| Inner Display | 7.6-inch, 1,500 nits | 7.6-inch | 10.2-inch tri-fold | 6.3-inch / 8.0-inch |
| Cover Display | 5.4-inch, 1,600 nits | 5.5-inch | 6.4-inch | 6.3-inch |
| Chip | Apple A20 Pro (2nm) | Snapdragon 8 Elite Gen 5 (3nm) | Kirin 9050 Pro | Xring O3 |
| Telephoto Lens | None | None | 48MP telephoto | None |
| Biometrics | Side-mounted Touch ID | Optical fingerprint | 3D face + fingerprint | Ultrasonic fingerprint |
| Stylus Support | Apple Pencil | S Pen | Stylus | Stylus |
Performance: Four Chips Go Head-to-Head
| Chip | Process Node | Performance Tier | Gaming | AI |
|---|---|---|---|---|
| Apple A20 Pro | 2nm | All-round | Max settings | 32-core NPU |
| Snapdragon 8 Elite Gen 5 (Z Fold8) | 3nm | Well-balanced | Stable at high settings | Above average |
| Xring O3 (Xiaomi 18 Fold) | 3nm | Peak benchmark scores (AnTuTu ~5.22M) | To be verified | Above average |
| Kirin 9050 Pro (Mate XT 2) | 5nm-class | Daily use | Mid settings | Strong NPU |
Key takeaways:
- A20 Pro is the most complete — 2nm across CPU/GPU/NPU, with a vapor chamber 3x larger than the iPhone 17 Pro’s, and that efficiency edge matters more in a space-constrained foldable.
- Snapdragon 8 Elite Gen 5 is the most balanced — efficient TSMC 3nm, with solid sustained performance and battery life in publicly reported foldable tests.
- Xring O3 leads on paper — AnTuTu ~5.22M is the highest here, but it is China-first and long-term software support is unknown.
- Kirin 9050 Pro trails at peak — demanding games and 8K editing show its limits, though Huawei’s NPU and AI scheduling keep daily use smooth.
Verdict: iPhone Duo (A20 Pro) > Xiaomi 18 Fold (Xring O3) ≈ Z Fold8 (Snapdragon 8E5) » Mate XT 2 (Kirin 9050 Pro).
Feel and Weight: Z Fold8 Dominates
| Model | Weight | Feel in Hand |
|---|---|---|
| Z Fold8 | 201 g | Almost a regular smartphone — easy one-handed use. |
| Xiaomi 18 Fold | ~250 g | Solid, but noticeably heavier. |
| iPhone Duo | 254 g (heaviest) | Sturdy aluminum frame, but the weight is obvious. |
| Mate XT 2 | ~297 g | Tri-fold behemoth — best used with two hands. |
Standout Features
- iPhone Duo: Apple Pencil, iOS ecosystem, strong video — but no telephoto lens.
- Z Fold8: IP48 water resistance, Galaxy AI, S Pen — also no telephoto.
- Mate XT 2: 10.2-inch tri-fold display, 48MP telephoto with variable aperture, ECG, privacy screen — the most feature-packed overall.
- Xiaomi 18 Fold: silicon nitride ceramic body and satellite connectivity.
Which One Should You Buy?
| Your Priority | Recommendation |
|---|---|
| Best performance, Apple ecosystem, Pencil | iPhone Duo |
| Lightest, most mature, water resistance | Z Fold8 |
| Samsung ecosystem, S Pen | Z Fold8 |
| Maximum versatility, tri-fold innovation, telephoto | Mate XT 2 (if budget is no object) |
| Raw specs, value-focused | Xiaomi 18 Fold |
Bottom Line
Performance: the A20 Pro leads, but the Snapdragon 8 Elite Gen 5 and Xring O3 are close behind in practice. The clear laggard is the Kirin 9050 Pro — worth remembering if you play demanding 3D games.
Smartest all-around pick: if weight and pocket space matter most, the Z Fold8 (201 g, US$1,899.99, most refined) is hard to beat; for Apple build quality and Pencil support at any weight, the iPhone Duo is compelling, pending official pricing. Foldables aren’t just about benchmarks — they’re about how often you’ll actually reach for that unfolded screen.
