Xiaomi 15 Ultra Review: 15-Day Hands-On Experience & Honest User Feedback

I rushed to reserve it right after launch—this is the first Xiaomi Ultra model since the 12s Ultra that truly feels like a massive upgrade in performance. Since the MixC store closed, all my contacts switched to Shenye, which is too far, so I had to scramble to find a nearby store. After checking several locations, I finally secured the black/silver Xiaomi 15 Ultra 512GB version.

As an early reservation, I scored a launch gift pack, a tripod, and a voucher—but seeing others walk away with way more goodies made me feel a bit shortchanged. And right after my purchase, they announced trade-in deals with national subsidies… talk about bad timing. Major FOMO!

👍 **The Good:**
– Perfectly balanced weight—no awkward top-heaviness.
– Stunning design with a premium camera aesthetic that pairs beautifully with my A7C2.
– Buttons got a legendary upgrade—rock-solid with zero wobble.
– The 200MP telephoto delivers jaw-dropping clarity; the entire imaging system is next-level.

– Full-focal-length LOG video support is a game-changer.
– Optical bokeh shines in both photos and videos—telephoto shots blur backgrounds naturally, no portrait mode needed.
– HyperOS 2.0 erases its predecessor’s flaws—buttery smooth with near-zero bugs unless you’re stress-testing for videos.

– Xiaomi-Mac connectivity works like a dream.

👊 **The Not-So-Good:**
– The oversized camera bump needs a redesign (à la 11 Ultra’s rectangular module)—it keeps jabbing my hand.
– Screen brightness tuning feels overly cautious; adjustments lag behind my Mix Fold 3.
– Extended photo/video sessions get toasty (maybe *too* efficient at heat dissipation?

).
– No MagSafe support or official magnetic case—the included case is a letdown.
– File transfers via Xiaomi Connect crawl without third-party Wi-Fi (e.g., hotspotting to an iPhone 16 Pro Max). Home Wi-Fi? Blazing fast. This needs a firmware fix ASAP.

⭐️ **Verdict:**
A no-brainer for photography enthusiasts.
