Xiaomi 15 5G AI (512GB + 12GB) Review: Compact Powerhouse with Leica Magic

In a smartphone market dominated by massive screens and even larger price tags, the Xiaomi 15 5G AI stands out as a breath of fresh air. Announced in October 2024 and now widely available globally, this compact flagship (measuring just 152.3 x 71.2 x 8.08mm and weighing around 191g) packs premium specs into a pocket-friendly form factor. With its 6.36-inch display, Snapdragon 8 Elite processor, 12GB RAM, 512GB storage, and a Leica-tuned triple 50MP camera system, it’s designed for users who want flagship performance without the bulk. Priced at approximately $760 globally (with regional variations—around €850 in Europe and ₹65,000 in India), the 512GB/12GB variant offers exceptional value compared to rivals like the iPhone 16 ($799 for less storage) or Galaxy S25 ($800+).

I’ve spent the past few weeks using the Xiaomi 15 as my daily driver, testing everything from casual browsing to intensive gaming and photography during a trip through urban and scenic spots. Here’s my breakdown of its strengths, quirks, and whether it’s worth your cash.

Design and Build: Premium and Portable

The Xiaomi 15 feels like a high-end gem right out of the box. Its aviation-grade aluminum frame is wrapped in a textured glass back (available in Black, White, Green, or Liquid Silver), which not only looks sleek but also provides a grippy, fingerprint-resistant finish. At 8.08mm thick, it’s slimmer than most flagships, making one-handed use effortless—perfect for typing, scrolling, or quick selfies.

IP68 dust and water resistance adds peace of mind for everyday mishaps, and the compact size (6.36 inches diagonally) is a rarity in 2025, rivaling the iPhone 16’s portability but with more vibrant colors. The large camera bump on the back is a bit protrusive (it wobbles on flat surfaces), but the Leica branding screams premium. Battery life is stellar for its 5,400mAh capacity (global version), easily lasting 7-8 hours of screen-on time with mixed use, and 90W wired charging juices it up to 100% in under 30 minutes. Wireless charging at 50W is a nice bonus, though no charger is included in the box outside China.

Pros: Superb ergonomics, durable build, fast charging.
Cons: Camera module could be less obtrusive; no expandable storage.

Display: Crisp and Eye-Friendly

The 6.36-inch LTPO OLED panel is a highlight, boasting a 1.5K resolution (2670 x 1200), 120Hz adaptive refresh rate, and a blistering 3,200 nits peak brightness. HDR10+ and Dolby Vision support make Netflix binges or YouTube clips pop with deep blacks and vivid colors—outshining the iPhone 16’s display in brightness tests. Xiaomi’s AI-driven eye comfort features, like adaptive color modes and blue-light reduction, minimize fatigue during long sessions.

It’s protected by Gorilla Glass Victus 2, and the slim bezels give it a modern, immersive vibe without feeling cramped. Gamers will love the smooth scrolling and 480Hz touch sampling rate.

Pros: Bright, responsive, and color-accurate.
Cons: None worth noting—it’s top-tier.

Performance: Blazing Fast with AI Smarts

Powered by the Qualcomm Snapdragon 8 Elite (3nm process), paired with 12GB LPDDR5X RAM and 512GB UFS 4.0 storage, the Xiaomi 15 flies through tasks. Benchmark scores rival the OnePlus 13: Geekbench 6 single-core at ~3,200 and multi-core at ~10,000; AnTuTu around 2.2 million. Everyday use is buttery—app switching is instant, and multitasking with 20+ apps open shows no lag.

The “AI” in the name shines here: HyperOS 2 (based on Android 15) integrates Gemini AI for real-time features like object eraser in photos, smart transcription in calls, and predictive text that actually learns your habits. Gaming? Titles like Genshin Impact run at max settings with minimal throttling, thanks to the advanced vapor chamber cooling. 5G connectivity is robust (supporting SA/NSA bands globally), with Wi-Fi 7 and Bluetooth 5.4 for future-proofing.

That said, HyperOS comes bloated with pre-installed apps (e.g., Mi Browser, GetApps), though most can be uninstalled. It’s a minor annoyance on an otherwise fluid OS promising 4 years of updates.

Pros: Unmatched speed, AI perks enhance usability.
Cons: Some bloatware; occasional warmth during extended gaming.

Camera: Leica Excellence in a Triple Threat

The star of the show is the Leica-co-engineered triple 50MP setup: main (Light Fusion 900 sensor with OIS), ultrawide, and 3.5x telephoto. No periscope lens like the Pro, but it punches above its weight. Daytime shots are razor-sharp with natural colors and excellent dynamic range—Leica’s Vibrant and Authentic modes let you toggle between punchy and true-to-life looks. Low-light performance is impressive, with minimal noise and fast autofocus, though some color casts appear in extreme shadows.

Zoom is versatile up to 30x digital (solid at 3.5x optical), and portraits nail subject separation. The 32MP front camera delivers flattering selfies with AI beautification that’s subtle by default. Video hits 8K/30fps or 4K/60fps with gyro-EIS for steady footage, and Leica’s cinematic filters add flair.

DXOMARK scores it 147 overall—strong in photo (wide DR, low noise) but dockable in group shots for shallower depth. It’s not quite Pixel-level computational magic, but for $760, it’s a photography beast.

Pros: Versatile Leica system, great low-light and video.
Cons: Ultrawide lacks autofocus; minor low-light inconsistencies.

Verdict: 4.5/5 – A Compact Flagship Worth Hunting Down

The Xiaomi 15 5G AI (512GB/12GB) is a triumph for anyone tired of phablets—delivering iPhone-beating performance, Leica-caliber cameras, and all-day battery in a svelte package. At $760, it’s a steal for the storage and power, undercutting competitors while offering more RAM and faster charging. Drawbacks like software bloat and limited US availability (import via third parties) keep it from perfection, but if you’re in Europe, Asia, or willing to shop globally, this is 2025’s best small flagship.

Buy if: You crave compact power with pro cameras.
Skip if: You need US carrier optimization or hate tweaking software.

Overall, the Xiaomi 15 proves you don’t need a giant screen to go big on features. Highly recommended.
