Xiaomi 17 Ultra Review: Lighter, Flatter, and Sharper Than Ever

Within the renamed family, the Xiaomi 17 Ultra is the boldest expression of what Xiaomi thinks a 2026 flagship should be. It arrives globally as a big, confident phone that refuses to blend into the background. It is unapologetically camera-centric, and it is packed with specs that read like a wish list.

On paper, Xiaomi has the ingredients to back that up. You get a 6.9-inch LTPO AMOLED display, a Leica-tuned triple camera system with a 200 MP periscope telephoto, and Qualcomm’s Snapdragon 8 Elite Gen 5. The global model carries a 6,000 mAh battery with 90W wired and 50W wireless charging, which is still a serious setup even before real-world testing.

The camera hardware also shifts in meaningful ways, with the main sensor switching from Sony to OmniVision, and the zoom strategy changing from two telephoto cameras to one lens with continuous 75 mm to 100 mm optical zoom. So does the Xiaomi 17 Ultra deliver ultra-level performance where it counts. After two weeks with it, here is what I found.

Aesthetics

The Xiaomi 17 Ultra is not a phone that tries to disappear in your hand or your pocket. The gigantic circular Leica camera island still dominates the rear panel, just like on the previous model, but there is a subtle shift in design language. With a flatter back panel and flat side frame, the 17 Ultra leans into a cleaner, more minimal look than the Xiaomi 15 Ultra. The small Ultra logo with its red underline sitting above the camera bump adds a bit of character without turning the phone into a billboard.

The color palette for the global model leans into classic tones. Xiaomi focuses on black, white, and green for most markets, skipping the violet shade that appears in China. The Starlit Green unit I received is the standout, with a deep moss green base and speckling that catches the light like a dusting of stars, which makes the name feel earned. The black option looks stealthy, but the red accent on the camera ring keeps it from feeling flat, while the white version goes for a high contrast look with the black camera bump and a silver ring and side frame to tie it all together. If you are coming from the Xiaomi 15 Ultra, the evolution feels more like refinement than reinvention, yet the 17 Ultra looks more cohesive and more modern from the rear.

Ergonomics

The first thing I expected to notice when I pick up the Xiaomi 17 Ultra is the weight and thickness. The phone uses a large battery, a complex camera stack, and a sturdy frame, and all of that adds up in the hand. That said, I was pleasantly surprised. At 8.29mm thickness and about 219g, Xiaomi managed to make the 17 Ultra the slimmest and lightest among its Ultra series. The device is still big and not exactly a lightweight phone, but it feels a lot more comfortable to hold than your eyes perceive.

Ergonomically, the device feels well-balanced in the hand, which is a welcoming improvement from the top-heavy feel you get from holding the Xiaomi 15 Ultra. Xiaomi 17 Ultra adapts a flat display, for the first time for its Ultra line, and helps with the grip. Because it’s well-balanced, the camera bump becomes a natural resting point on the back, which can actually improve grip. At the same time, this is not a one-handed phone in any universe, and if you are coming from something smaller, you will need to adjust how you hold it, how you pocket it, and even how you reach for the top corners of the screen.

The global Xiaomi 17 Ultra uses a 6,000 mAh silicon-carbon battery instead of the 6,800 mAh cell in the China model. Even with the smaller capacity, it should still be enough for a full heavy day for most people. Charging is excellent with 90 W wired and 50 W wireless, and the 90 W wired mode supports PPS or Programmable Power Supply, so you can get true fast charging with any PPS-compatible USB-C charger, not only Xiaomi’s own adapter.

Performance

The display on the Xiaomi 17 Ultra is built to impress at first sight. It is a 6.9-inch LTPO AMOLED panel with 120 Hz refresh, a 1.5K class resolution at around 1200 x 2608 pixels, and a claimed 3500 nits peak brightness. It looks sharp and vibrant, and the huge screen makes movies, games, and photo editing feel more immersive. Xiaomi also adds TUV Rheinland certifications for low blue light, flicker-free performance, and circadian-friendly tuning, which are designed to reduce eye fatigue during long viewing sessions.

The Xiaomi 17 Ultra is powered by Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, and the global configurations come with 16GB of RAM paired with either 512GB or 1TB of storage. It is genuinely nice to see a 1TB option offered globally, since that is still not something every flagship brings outside China. The phone flies through heavy multitasking, high refresh rate gaming, and demanding camera workloads without stutter. On the software side, it runs Android 16 with Xiaomi’s HyperOS 3, which is Xiaomi’s unified platform designed to feel lighter and more connected across phones, tablets, and other devices.

The camera system is where the Xiaomi 17 Ultra really tries to separate itself. Xiaomi drops the older quad camera approach and commits to a triple setup. The main camera is a 23-mm equivalent 50 MP unit with an f/1.67 aperture, OIS, and OmniVision’s Light Fusion 1050L sensor. The 75-100mm equivalent telephoto is a 200 MP periscope with OIS using Samsung’s HPE sensor, with a f/2.39-2.96 aperture. Rounding it out is a 50 MP 14-mm equivalent ultra-wide with an f/2.2 aperture using Samsung’s JN5 sensor.

On the main camera, Xiaomi pairs the Light Fusion 1050L sensor with LOFIC technology. LOFIC stands for Lateral Overflow Integration Capacitor, and it is designed to reduce highlight clipping by giving each pixel extra headroom before bright areas turn into flat white. In practice, it helps keep texture in skies and reflections while still holding onto shadow detail in high contrast scenes.

Zoom is the other headline change. Instead of dual telephoto cameras, Xiaomi uses a floating lens structure to deliver continuous optical zoom from 75 mm to 100 mm, which makes it easy to pick between framing without obvious digital cropping. The limitation is that the range is fairly tight, so it is more about fine-tuning perspective than dramatically pulling faraway subjects closer. There is also a close-up trade-off, since the telephoto now focuses down to about 30 cm rather than the 10 cm I could get on the Xiaomi 15 Ultra, so it is less useful as a pseudo macro lens.

In real use, both the main camera and the telephoto produce excellent images with wide dynamic range, natural color, and strong detail in various lighting conditions. The images look clean rather than overprocessed or oversharpened. Portrait mode is especially flexible, offering eight focal lengths from 23 mm through 100 mm equivalents, with pleasant bokeh and strong separation, even if it can occasionally miss a fine strand of hair when I pixel peep. I also noticed the phone can get warm even after relatively short camera use, and hopefully Xiaomi can improve this with future updates.

The ultrawide is solid but a step behind the main and telephoto in refinement. The upgraded 50 megapixel front camera with autofocus is a nice quality of life improvement, and it looks great in good light. In backlight or low light, selfies can come out a bit soft as the processing works harder to control noise.

The Xiaomi 17 Ultra’s triple camera system can shoot video up to 8K at 30 fps, and it also offers 4K at up to 120 fps, although the ultrawide tops out at 4K at 60 fps. The front camera can record up to 4K at 60 fps, which is plenty for vlogs and high-quality selfies. Dolby Vision is supported across the cameras, and Xiaomi also includes creator-friendly tools like LOG recording up to 4K at 120 fps with stabilization on, plus LUT import for quicker grading and a more consistent look.

In performance, the 17 Ultra generally produces sharp, well-exposed footage with a fairly wide dynamic range, and stabilization stays strong when I am walking or panning. Low-light video also holds up well, with impressive detail for a phone, thanks in part to the large main sensor. Autofocus is usually smooth, but it can struggle in tricky conditions like backlit scenes or low light, where it may hesitate or hunt before it locks.

The Xiaomi 17 Ultra China version gets a 6,800mAh battery, but globally, it comes with a 6,000mAh battery. It should last you a full day, even with heavy use. It supports 90W wired charge and 50W wireless charge. 90W wired charge is PPS, so you can take full advantage of fast charging with a PPS compatible charger, not just with Xiaomi’s proprietary brick.

Sustainability

Xiaomi’s sustainability story for the 17 Ultra is mostly about longevity rather than eco materials. The phone uses Xiaomi Shield Glass 3.0 on the front, and it carries an IP68 rating, which should help it survive years of drops, rain, and daily wear without needing an early replacement. That kind of durability matters because the most sustainable phone is often the one you do not have to replace early.

Software support strengthens that long-life angle. Xiaomi promises five major OS updates and six years of security updates, which is not class-leading, but it is enough to make long-term ownership feel realistic at this price. It also makes the phone a safer buy if you plan to keep it for several years or pass it on later. What Xiaomi does not really emphasize, at least from what I can find, is the use of recycled or more sustainable materials in the phone itself.

Value

For global buyers, the Xiaomi 17 Ultra starts at EUR 1,499, which is roughly $1,620 USD, for 16GB/512GB, with the 16GB plus 1TB configuration expected around EUR 1,699, roughly $1,840 USD. That puts it directly in the same bracket as the most expensive Samsung Galaxy and iPhone models. If you look at what the Xiaomi 17 Ultra offers, it is easy to see the value in hardware alone, especially in cameras, battery, and storage.

The challenge is that Xiaomi is not only competing with Samsung and Apple, but also with other camera-focused Android flagships that are expected to land this year. That means the 17 Ultra has to win on the full experience, not just its spec sheet, especially when buyers are cross-shopping within the same premium price tier. Even so, the 17 Ultra can justify its price if you care most about its Leica-tuned imaging, huge display, and fast charging rather than ecosystem lock-in.

Verdict

The Xiaomi 17 Ultra is one of the most complete camera-first flagships Xiaomi has shipped for the global market. It nails the fundamentals with a huge, bright display, top-tier performance, and charging that makes most rivals feel slow and old-fashioned. The bigger story is how coherent the imaging experience feels, since the main and telephoto cameras deliver natural color, wide dynamic range, and consistent results across lenses.

Of course, there are real trade-offs, too. The new 75 mm to 100 mm continuous zoom is great for framing, but it is not a massive jump in reach, and the longer minimum focus distance makes the telephoto less useful for pseudo macro shots than the Xiaomi 15 Ultra. The global price also puts it in direct competition with the biggest names, so this is no longer a value flagship by default.  Still, there is no doubt the 17 Ultra earns its Ultra name. It delivers a huge, gorgeous screen, genuinely fast charging, and one of the most enjoyable still photo experiences you can get on a phone, with Leica-tuned color that looks natural rather than overcooked. If those are your priorities, the Xiaomi 17 Ultra is an easy flagship to love.
