Xiaomi 15 Ultra 512GB Silver Chrome

Das Xiaomi 15 Ultra gehört definitiv zu den besten Kamera-Smartphones auf dem Markt. Vor allem für Fotoenthusiasten bietet es unzählige Optionen. Auch die Ausstattung lässt keine Wünsche offen. In Sachen Software hinkt Xiaomi der Konkurrenz teils aber noch hinterher. So fehlt etwa eine systemweit agierende KI. Leider ist das Gerät zudem sehr kopflastig.

Schwergewicht. Das Xiaomi 15 Ultra will die Kamera-Speerspitze für Smartphones sein und setzt dabei weiterhin auf die Kooperation mit Leica. Dafür werden gleich zwei neue Kamera-Sensoren verbaut und treiben die Pixelzahl des Hauptsetups auf 350 MPix. Ob es dem eigenen Anspruch gerecht wird und was es sonst noch bietet, klärt unser Test.

Heroic hardware and nuanced processing hand the Xiaomi 15 Ultra the phone photography crown. It’s an imposing flagship everywhere else, too.

If you want a well-rounded software experience, the best AI tools, or a gaming handset that stays cool under pressure, this isn't the phone for you, but if you can live with those flaws to enjoy the absolute best smartphone camera package money can buy, bar none, combined with amazing battery life and fast universal charging, I recommend the Xiaomi 15 without hesitation.

Xiaomi is bringing sizeable upgrades to the 15 Ultra; there's a new 200MP telephoto camera that takes amazing photos, a bigger 5410mAh battery that lasts over a day, and the latest hardware currently available. There's still a 1-inch sensor at the back, and it continues to take breathtaking photos most of the time. Combine that with a brighter AMOLED panel and better software optimization, and the 15 Ultra is a delight to use. There are issues with overheating at times and the camera being inconsistent with HDR imagery, but on the whole, the 15 Ultra is without a doubt one of the best phones I used in 2025.

The Xiaomi 15 Ultra has an awful lot of things going for it, with a gorgeous design, strong camera performance and all the benefits of the latest mobile hardware. It's just a shame that its AI performance is pretty lackluster, and that it won't be going on sale in the U.S.

Xiaomi's latest everything-but-the-kitchen-sink uber-flagship comes with an even more capable Leica-supported camera than before, a stunning display, top-tier performance, and some useful AI tools. Underwhelming battery longevity was a surprise weakness, while Xiaomi still needs to work on its user experience. Availability in more markets would have been nice, too.

The Xiaomi 15 Ultra is one of, if not the best, camera phone available in 2025 – though it does come at a premium. From the 1-inch-backed primary camera to the versatile floating telephoto and high-res periscope lenses, it’s almost effortless to capture a stunningly detailed image regardless of shooting conditions. It’s not just a camera phone either, with a top-end screen, powerful chipset and all-day battery life to boot.
