Points positifs
Points négatifs
Le Xiaomi 17 Ultra est présenté comme un produit phare ultra-premium axé sur la photographie, avec un système d'appareil photo de marque Leica doté d'un capteur principal de 1 pouce. Sa principale amélioration est un téléobjectif de 200 mégapixels avec zoom optique continu, destiné à fournir des portraits de haut niveau et des résultats à longue distance. Les avis soulignent également des améliorations significatives en dehors de l'appareil photo, notamment un écran plat LTPO AMOLED plus grand de 6,9 pouces et une batterie silicium-carbone de 6 800 mAh. Les performances sont dignes d'un flagship grâce au Snapdragon 8 Elite Gen 5 de Qualcomm et à la carte graphique Adreno 840, ainsi qu'à une connectivité moderne comme le Wi-Fi 7 et une prise en charge étendue de la bande 5G. La durabilité et les caractéristiques sont solides sur le papier avec une protection IP68/IP69, des haut-parleurs stéréo et HyperOS sur Android 16. Les mises en garde mentionnées comprennent le prix élevé de 950 euros, le poids important et les limitations logicielles possibles en fonction de l'unité/région.

Xiaomi 17 Ultra unboxing & review, the global version of the Xiaomi 17 Ultra review with camera test.

Xiaomi has a pair of excellent photography kits for the 17 Ultra, so let's do an unboxing. This year, there's a Photography Kit Pro and a standard Photography Kit, each gives the phone a bit more grip for one-handed use and a dedicated camera shutter button. But personally, I think if you're going to invest in one, you might as well go Pro.

This is the Xiaomi 17 Ultra review after two months* -- okay, okay, the two months isn't exactly accurate, because I tested the China Xiaomi 17 Ultra by Leica for a month and half, and then this global version of the standard Ultra for two weeks. But still, other than some superficial changes, the camera system of both models of the Ultra I tested are nearly identical, so hence I said I have been using it for two months. The Xiaomi 17 Ultra runs on the Snapdragon 8 Elite Gen 5 and features a top-tier camera system headlined by a 1-inch sensor main camera and a Periscope zoom with variable aperture between 75mm and 100mm.

Xiaomi’s latest 17 Ultra flagship phone has officially landed on the global stage, and it’s arguably the most ambitious camera-centric smartphone we’ve seen this year. Check out our video review to learn ALL YOU NEED TO KNOW about the phone's top features, build and screen quality, battery life, performance, and camera image quality.

EN→FRAs it currently stands, the Xiaomi 17 Ultra is likely the best camera phone outside of China. The Oppo Find X9 Ultra and the vivo X300 Ultra will be the only real competitors, if they make it outside of China. Maybe the video recording capability is the only thing that keeps us from giving this phone a perfect score.

EN→FRThis all brings me to the frustrating inconsistency with Xiaomi phones, which has been highlighted by my time with the 17 Ultra. The last Xiaomi phone I reviewed was the 15T Pro, where the battery life was stellar, Wi-Fi performance was strong, and the hardware felt durable and expensive. It’s a shame Xiaomi hasn’t nailed the fundamentals with the 17 Ultra, because the camera is fantastic, and a return to form after the 15 Ultra’s slight misstep.

EN→FRThere's no doubt that the Xiaomi 17 Ultra is one of the best camera phones of 2026. Xiaomi did a great job with the design this year, and the phone feels better to hold and use than its predecessors. The hardware is among the best you'll get, the bigger 6.9-inch OLED is a delight to use, and the 6,000mAh battery easily lasts a day.

EN→FRIf you want the very best Xiaomi has to offer, then get this phone. Yes, it is quite expensive, but it also offers a lot. Its performance is outstanding, and the same goes for the display. The audio output is great, and so is the battery life despite the fact that the capacity is lower than in a Chinese model.

EN→FRXiaomi 17 Ultra review: Fantastic cameras As the latest in a line of great camera phones, the Xiaomi 17 Ultra has a lot to live up to. But the good news is this phone delivers, and in spades. Featuring a new 1-inch sensor with LOFIC (Lateral Overflow Integration Capacity) technology and a 200MP periscope 75-100mm zoom lens with mechanical optical zoom, this camera phone is one of the best available (until next year, I guess). Like last year's Xiaomi 15 Ultra (Xiaomi decided to skip the number 16 to match the iPhone 17 series), the phone features a circular bump at the back, but that's where the similarities end.

EN→FRAll in all, the Xiaomi 17 Ultra is one of the best camera phones I've tested, and there's no doubt there are a lot of technological improvements that make it excellent. While it doesn't pack a telephoto extender like the Vivo X300 for even more zoom, I'd argue that the current range in the 17 Ultra is more than enough, especially for street photography.

The Xiaomi 17 Ultra (Leica Leitzphone) features a massive LOFIC sensor and a mechanical Master Zoom Ring for an authentic photography experience. We test whether the $2,300 price tag is justified by putting its professional-grade Leica optics and Snapdragon 8 Elite power to the ultimate test.

Xiaomi 17 Ultra isn’t perfect. But as a camera? With a 1-inch sensor, continuous optical zoom, and Leica color science — this might be the most exciting camera phone I’ve used in years. If you care about photography more than polish, you’ll want to watch this review.

EN→FRI have my problems with the Xiaomi 17 Ultra – the software is still among my least favourites, the camera module is too chunky and the lower screen resolution and cheap feeling of the fiberglass rear don’t befit a phone of this price. But even still, it gets enough right elsewhere to earn my recommendation. Performance is among the best of any phone that we’ve tested to date, the cameras are sharp, versatile and accessible, battery life is decent and great strides have been made to deliver a slimmer, lighter and altogether more manageable flagship phone.

EN→FRThe Xiaomi 17 Ultra makes one thing very clear: this is a camera-first flagship in every sense. From the 1-inch primary sensor to the new continuous optical zoom telephoto system, the phone is engineered around photography rather than just adding impressive specs for the sake of it. In both daylight and low light, it consistently delivers results that are among the best I’ve seen on a smartphone so far this year. Beyond the cameras, the upgrades are meaningful. A larger 6.9-inch flat display, a massive 6,800mAh battery without added bulk, and the Snapdragon 8 Gen 5 chipset all make this a serious flagship package. The only caveat is that this Chinese unit has certain software limitations, so it’s hard to judge the full experience until the global version arrives.

EN→FRWe put the Xiaomi 17 Ultra through our rigorous DXOMARK Camera test suite to measure its performance in photo, video, and zoom quality from an end-user perspective. This article breaks down how the device fared in a variety of tests and several common use cases and is intended to highlight the most important results of our testing with an extract of the captured data. The Xiaomi 17 Ultra delivers an excellent performance in the DXOMARK Camera tests. In many test areas it is a significant upgrade over its predecessor 15 Ultra and is getting close to the very best flagship devices on the market – without quite matching them, however. Photo performance is particularly impressive.

The Xiaomi 17 Ultra comes in two flavors - besides the standard phone, you also get this very special edition that we are reviewing today - Xiaomi 17 Ultra by Leica. What do you get extra with this edition, and is it worth paying extra for? To Leica or NOT to Leica? That is the question! Check out our video review to learn the answer, along with ALL YOU NEED TO KNOW about the phone's build and screen quality, battery life, performance, and camera image quality.

EN→FRDespite the hefty price tag, which is even higher than last year, the Xiaomi 17 Ultra is one of the best flagship cameraphones you can get right now. Just like the rest of the flagship phones, the 17 Ultra has an excellent display, fast chipset, snappy charging and long battery life, although that last bit isn't a given. However, the improved telephoto and selfie cameras, along with the exceptional main camera performance, make the device one of the best in its class. We also didn't feel the absence of the second 3x telephoto camera either, as the current 200MP telephoto shooter with continuous optical zoom and close-distance focusing covers all bases.

Xiaomi really caught everyone off guard by dropping the Xiaomi 17 Ultra months ahead of schedule. Usually, we have to wait until spring for the "Ultra" flagship, but it's already here to kick off 2026 with some massive changes. The design has seen a complete overhaul. The curved screen is gone, replaced by a fully flat display that feels much more like the Pro Max. It’s significantly better for gaming and applying screen protectors, even if the flat back feels a bit sharper in the hand compared to the older 15 Ultra. But the real controversy is the camera system.

EN→FRThe Xiaomi 17 Ultra was announced on December 25, 2025, and released just two days later, positioning itself firmly in the ultra-premium flagship segment. It comes in two versions, including a Leica Edition with a mechanical zoom ring, which immediately sets it apart for camera enthusiasts. The phone feels solid and premium with its glass front, aluminum frame, and fiber-reinforced plastic or eco-leather back. At 230 grams and 8.5 mm thickness, it is heavy but well-balanced.

The Xiaomi 17 Ultra has finally landed, and it’s doing something we haven't seen from an "Ultra" phone in years—it actually went on a diet. After generations of massive, heavy camera bricks, Xiaomi managed to pack a ridiculously powerful imaging system into a chassis that’s only 8.29mm thick. But the real story here isn't just the improved ergonomics; it's the brand-new 200MP variable telephoto lens that changes how we shoot portraits..

Qualcomm Adreno 840: Unité graphique intégrée dans le SoC Qualcomm Snapdragon 8 Elite Gen 5 pour smartphones avec trois tranches à 1,2 GHz chacune. Selon Qualcomm, elle est 23 % plus rapide que celle de la génération précédente (Adreno 830).
Ces cartes devraient être capables de faire tourner tout les jeux d'aujourd'hui, mais la plupart d'entre eux uniquement en détails moyens ou faibles et avec des résolution basses. Les plus vieux jeux ou les jeux moins gourmands restent jouables avec de beaux graphismes.
