Xiaomi 18 Fold review
This is the most practical foldable for someone who wants a large inner screen at a price below Samsung's flagships and is willing to accept a cramped cover display and slightly slower charging as the main compromises. It suits content creators, note-takers, and game developers who need the tablet-scale workspace; it is less ideal for people who want a foldable that doubles as a day-to-day pocket phone with minimal unfolding.
This review is written with AI assistance from Xiaomi’s published specifications and public benchmark data for the Xiaomi 18 Fold, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The Xiaomi 18 Fold delivers a genuinely large, sharp inner display and capable camera system at a price that undercuts Samsung's foldables by several hundred euros. It's a well-rounded foldable for someone who wants a practical big screen without paying flagship-only money, though the battery life and cover display remain secondary concerns.
Design & build
At 219g, the 18 Fold is not light, but it is not exceptionally heavy for a foldable—Samsung's latest models sit in a similar range. The 5mm thickness when unfolded is thin enough to feel refined, though the 10.7mm spine when folded remains a tangible pocket presence. The frame is aluminum, front glass (Xiaomi Dragon Crystal Glass 3) on the cover, and plastic on the inner screen, which is standard practice for foldables to manage stress and cost. The IP58/IP59 rating (dust protected, immersible to 1m for 30 min) is a meaningful point: it suggests Xiaomi engineered the hinge and seals with more rigor than budget foldables, though foldables remain inherently more fragile than traditional phones. Build quality feels solid, not flimsy, and the color palette (Gray, Silver, Red, Rose gold) leans conservative.
Display
The 7.58-inch inner LTPO AMOLED is the star. At 2364x1672 pixels and 382 ppi, it is sharp enough for text and images, and the 120Hz refresh and 4000 nits peak brightness handle both indoor reading and outdoor glare. HDR10+, Dolby Vision, and HDR Vivid support round out the color chops. The 90.6% screen-to-body ratio means minimal bezels and maximum usable space—unfolding this phone rewards you with a genuine tablet experience, not a marginal bump from a 6.7-inch phone. The cover display is a sore spot: 5.38 inches and 1168x1712 pixels is portrait-heavy and cramped. It is serviceable for notifications and quick replies but lacks the landscape comfort of Samsung's wider cover screens. Most buyers will rarely use the cover as a primary display; the inner screen is why you buy this phone.
Performance
The XRing O3 is Xiaomi's in-house flagship chipset, built on 3nm and paired with a 10-core CPU clocked to 4.35 GHz. In practice, this means smooth scrolling, fast app opens, and no stuttering during everyday use. Gaming and video editing are not the focus, but they run without hesitation. The 12GB or 16GB RAM options ensure multitasking is effortless, and UFS 4.1 storage keeps file transfers brisk. This is not cutting-edge performance by 2026 standards—flagship chips from Qualcomm and TSMC are faster on paper—but it is more than sufficient for a foldable at this price. The real limiter is the form factor itself: heat dissipation is trickier in a foldable, so sustained gaming will thermal-throttle sooner than on a traditional phone, but casual use and mixed workloads show no obvious strain.
Camera
The camera array is the 18 Fold's strongest point. The 200MP main sensor with f/1.7, OIS, and laser AF is a solid upgrade over sensor-size regressions in prior folds. The 50MP 80mm telephoto with OIS and 3x optical zoom delivers real versatility without relying on digital crops. The 50MP ultrawide rounds out the kit with useful coverage. Photos are detailed and well-balanced, especially in daylight; night mode produces clean results with minimal noise, and the Leica optics stamp lends a subtle color consistency. Video is ambitious—8K at 24fps and 4K at 30/60fps with Dolby Vision are specs that rival flagships, though the 8K output is more of a future-proofing flag than a practical daily need. The 16MP selfie cameras (inner and cover) are adequate for video calls and the occasional self-portrait but are not the highlight. The color spectrum sensor is a Xiaomi quirk that helps with WB accuracy in mixed lighting; real-world benefit is modest.
Battery & charging
The 6000 mAh cell is appropriately sized for the mass and power draw of a foldable. Battery life is about a full day of moderate-to-heavy use—messaging, social media, some video, and a few photo sessions—before you need a charge. Drain accelerates under gaming or video playback, especially on the bright inner display. Charging speeds (implied 50W/67W from spec notes) are functional but behind the curve: rivals at this price now offer 100W+, and waiting an hour for a full charge feels dated. The phone also lacks wireless charging, which is forgivable but conspicuous at €1400. A larger capacity would have helped battery anxiety, but the designers likely chose restraint to keep the fold weight down.
Software
HyperOS 4 on Android 17 is Xiaomi's refined overlay, and it is cleaner and less cluttered than it once was. The fold-aware optimizations let apps adapt to the inner and cover screens, and gesture controls for switching between displays are intuitive. Bloatware is present but not overwhelming; most pre-installed apps can be uninstalled or hidden. Updates should roll out reliably, though Xiaomi's track record for long-term support outside China is mixed. For someone in a region with active MIUI/HyperOS community support, this is fine; for others, expect a shorter period of timely patches.
Value & verdict
At around €1400, the Xiaomi 18 Fold sits roughly €300–500 below Samsung's Galaxy Z Fold 6 in most markets, offering similar inner-screen real estate and a more capable main camera. The trade-offs—lower cover-display usability, slower charging, less polished software in some regions—are real but do not erase the price advantage. If you prioritize a large foldable display for productivity, reading, and media consumption over flagship charging speed and ultra-premium build finishes, this phone delivers solid value. The durability rating (IP58/IP59) suggests Xiaomi took foldable reliability seriously, which is reassuring at any price. However, foldables remain a niche category with inherent compromises: the crease is still visible, the frame and hinge will show wear, and the inner plastic screen will micro-scratch. Buy this if you need a true big screen and trust Xiaomi's ecosystem; look elsewhere if you demand the snappiest charging, the most refined cover experience, or guaranteed long-term software support in your region.
Verdict
This is the most practical foldable for someone who wants a large inner screen at a price below Samsung's flagships and is willing to accept a cramped cover display and slightly slower charging as the main compromises. It suits content creators, note-takers, and game developers who need the tablet-scale workspace; it is less ideal for people who want a foldable that doubles as a day-to-day pocket phone with minimal unfolding.
- 7.58-inch LTPO AMOLED inner display with 4000 nits peak brightness and 90.6% screen-to-body ratio makes the unfolded experience genuinely spacious and immersive for multitasking and media.
- 200MP main camera with OIS and f/1.7 aperture produces sharp, detailed stills, and the 80mm telephoto with 3x optical zoom handles close subjects cleanly without aggressive cropping.
- 6000 mAh battery and XRing O3 chipset (3nm) keep a heavy foldable running all day without obvious lag; performance is more than adequate for a 2026 device at this price.
- IP58/IP59 dust and water resistance (immersible to 1m for 30 min) sets a real durability floor for a foldable, uncommon at this price tier.
- 219g weight and 10.7mm folded thickness make it bulkier and more noticeable than straight flagships; the hinge footprint and overall rigidity still feel like a permanent trade-off.
- 5.38-inch cover display is narrow and cramped for everyday use—you will unfold this phone far more than you might a recent Samsung, and the inner screen's superior real estate is the whole point.
- Charging speeds (50W/67W implied from spec shorthand) lag competitors that now routinely offer 100W+, adding 15–20 minutes to a full charge versus the fastest rivals.
