The foldable war is heating up in 2025. On one side, we have Samsung's Galaxy Z Fold 6 — the refined veteran of the foldable game. On the other, Xiaomi’s Mix Fold 4, which brings serious power and sleek engineering at a competitive price. Both are packed with features. But which one should you buy?
Design & Build
The Galaxy Z Fold 6 offers a familiar design evolution — slimmer, lighter, and with improved durability thanks to Corning Gorilla Armor. Xiaomi’s Mix Fold 4 counters with a more compact frame and one of the thinnest foldable designs ever, continuing Xiaomi’s obsession with ultra-flat hardware.
Both use book-style folding with inner and outer displays. But the Mix Fold 4 is reportedly thinner and lighter, making it more pocket-friendly.
Display
- Galaxy Z Fold 6: 7.6" QXGA+ Dynamic AMOLED 2X (inner), 6.3" AMOLED (cover), 120Hz both
- Mix Fold 4: 8.03" AMOLED LTPO (inner), 6.56" AMOLED (outer), 120Hz both
Samsung wins slightly on brightness and color calibration, but Xiaomi offers more screen real estate inside.
Performance
Both phones are powered by the flagship Snapdragon 8 Gen 3 chip, paired with up to 16GB RAM and UFS 4.0 storage. Day-to-day use, multitasking, gaming — you won’t notice much difference in raw speed. Where Xiaomi edges ahead is in **thermal control**, thanks to its vapor chamber cooling tech.
Camera
This is where things get interesting:
- Galaxy Z Fold 6: 50MP main + 12MP ultra-wide + 10MP telephoto (3x optical)
- Mix Fold 4: 50MP Leica-tuned main + 50MP 2x telephoto + 12MP ultra-wide
Samsung holds its own, but Xiaomi’s partnership with Leica gives its photos a cinematic edge — especially in portraits and low-light shots.
Software
Samsung continues to lead with One UI’s multitasking features, Flex Mode, and better foldable app support. Xiaomi’s HyperOS 3.0, however, is catching up fast — especially with its **PC-like taskbar**, floating windows, and AI-enhanced split screen.
Battery Life
- Galaxy Z Fold 6: 4,400 mAh, 25W wired
- Mix Fold 4: 5,000 mAh, 67W wired fast charging
The Mix Fold 4 wins on both capacity and speed — it charges almost twice as fast and lasts longer due to Xiaomi’s power optimization in HyperOS.
Price & Availability
The Galaxy Z Fold 6 retails globally at around $1,799. The Mix Fold 4 is expected to be available primarily in China at launch, starting from ~$1,499 (converted). Global availability for Xiaomi may still be limited unless imported or expanded through EU/India channels.

Final Verdict
If you want the most polished foldable experience with global support and reliable updates, the Galaxy Z Fold 6 is still the foldable to beat. But if you’re after cutting-edge hardware, faster charging, and a more compact design — and you're okay importing — the Xiaomi Mix Fold 4 may offer more value.
Either way, 2025’s foldable race is officially on — and that’s great news for buyers looking beyond boring slabs.
