Xiaomi 17 Ultra Review: Making Galaxy S26 Ultra Sweat

0 Imran Shaikh Isrg
Xiaomi 17 Ultra review India 2026 - 1-inch LOFIC Leica camera, 200MP mechanical zoom, 90W charging at Rs 1,39,999

Xiaomi announced the 17 Ultra at MWC 2026 in Barcelona on February 28 - and the phone won Best in Show before it had even gone on sale anywhere. The reason was straightforward: a mechanical continuous optical zoom system on a 200MP periscope telephoto, ranging from 75mm to 100mm, is something no other smartphone on Earth has done. India launch followed on March 11, 2026, at ₹1,39,999 for the sole 16GB and 512GB variant. As of May 6, 2026, HDFC and ICICI cardholders get an instant ₹10,000 discount - bringing the effective price to ₹1,29,999. The Xiaomi 17 Ultra is the first product born from Xiaomi and Leica's upgraded "Strategic Co-creation Model" - a shift from the previous joint R and D arrangement to deep collaboration from product inception. After going through every serious review, long-term test, and real-world camera comparison published since launch, here is the complete picture of what this phone actually delivers.

Xiaomi 17 Ultra India Price and Availability

Variant Launch Price Effective Price (May 2026)
16GB + 512GB (Black or White) ₹1,39,999 ₹1,29,999 (HDFC / ICICI instant discount)

The Xiaomi 17 Ultra is available on Amazon India, mi.com, and offline Xiaomi stores across India in Black and White colour options. The Starlit Green variant seen at MWC 2026 is not part of the India lineup. Early bird buyers between March 13 and March 17 received the Photography Kit Pro - worth ₹19,999 - bundled free. It is now sold separately. A Jio benefits bundle worth ₹16,000 is available for Jio users purchasing the phone. Price has not changed significantly since launch - no meaningful street price drop as of May 9, 2026, beyond the bank card instant discounts.

At ₹1,39,999 retail, the Xiaomi 17 Ultra sits at the same price as the Samsung Galaxy S26 Ultra at launch, though the Galaxy S26 Ultra has since dropped to ₹1,18,990 on Amazon. That price gap - now ₹21,000 wider in Samsung's favour - is the most important context for anyone comparing the two in May 2026.

Design: First Flat Ultra - Thinner, Cleaner, Better to Hold

The Xiaomi 17 Ultra is the first phone in the Ultra lineup to feature a completely flat display - flat front, flat back, flat frame. Every previous Ultra used curved edges. Xiaomi has dialled back curvature with each generation, and 91mobiles' review noted that the 17 Ultra now presents a "cleaner, linear form with an ultra-thin bezel." The practical result: screen protectors actually fit properly, accidental edge touches disappear, and the grip is firmer during extended photography sessions.

The phone measures 8.29mm thick and weighs 218-219g depending on colour variant. The Black variant carries a red accent ring around the camera module - a distinctive visual choice that several reviewers specifically called out as looking great in person. The back uses composite fiberglass rather than glass, which reduces weight and makes the rear more resistant to everyday scratches. Xiaomi Shield Glass 3.0 covers the front. IP68 and IP69 ratings are both confirmed - the phone handles deep water immersion and high-pressure water jets, giving it a durability edge over the Galaxy S26 Ultra's IP68-only protection.

Compared to the Galaxy S26 Ultra (7.9mm, 214g), the Xiaomi 17 Ultra is slightly thicker and heavier. The S26 Ultra remains the slimmest and lightest Ultra-tier phone in 2026. But where the Xiaomi 17 Ultra improves on its own predecessor meaningfully is balance - the camera module has been repositioned higher and made more symmetrical, which reduces wrist fatigue during long shooting sessions.

Display: 6.9-inch Flat AMOLED at 3500 Nits - Genuine Outdoor Beast

Display Spec Xiaomi 17 Ultra Samsung Galaxy S26 Ultra
Size 6.9-inch LTPO AMOLED 6.9-inch Dynamic AMOLED 2X
Resolution 1.5K (2608 x 1200) QHD+ (1440 x 3120)
Refresh Rate 1-120Hz adaptive 1-120Hz adaptive
Peak Brightness 3,500 nits 2,600 nits
HDR Dolby Vision, HDR10+, 12-bit colour HDR10+ only
Privacy Display No Yes (world-first hardware)
PWM Dimming 1,920Hz (eye-care certified) Standard

The display runs at 3,500 nits peak brightness - 900 nits more than the Galaxy S26 Ultra. In outdoor conditions, this gap is visible and meaningful. The Xiaomi 17 Ultra's panel also supports 12-bit colour depth and Dolby Vision - two areas where the S26 Ultra falls short. TUV Rheinland Low Blue Light, Flicker Free, and Circadian Friendly certifications are all present - important for users who spend extended hours on the phone.

The honest gap is resolution. The Xiaomi 17 Ultra's 1.5K panel (2608 x 1200) is less sharp than the Galaxy S26 Ultra's QHD+ (1440 x 3120). In everyday use and video content, most reviewers did not find this difference impactful. For users who pixel-peep images on screen or demand maximum sharpness, Samsung's display has a clear resolution advantage. The Galaxy S26 Ultra also carries its unique hardware Privacy Display - which narrows viewing angles on demand - a feature the Xiaomi 17 Ultra has no equivalent to.

Performance: Snapdragon 8 Elite Gen 5 - Slightly Behind Galaxy Tuning, Ahead in Everything Else

Performance Detail
Chipset Qualcomm Snapdragon 8 Elite Gen 5 (3nm, peak 4.61GHz)
RAM 16GB LPDDR5X
Storage 512GB UFS 4.1
AnTuTu (V11) Over 3.6 million
Cooling IceLoop system
OS Android 16 + HyperOS 3
OS Updates 5 years OS + 6 years security patches
USB USB 3.2 Gen 2 (requires USB 3.2 cable, sold separately)

The Snapdragon 8 Elite Gen 5 in the Xiaomi 17 Ultra scored over 3.6 million on AnTuTu V11 in 91mobiles' testing - ahead of almost every other flagship in this price range. The one phone that scores higher is the Samsung Galaxy S26 Ultra, which uses a custom overclocked "for Galaxy" variant of the same chipset and scores over 3.9 million. In everyday use, this gap is completely invisible. Apps open instantly, multitasking is seamless, and HyperOS 3 on Android 16 runs smooth throughout.

USB 3.2 Gen 2 support is confirmed on the Xiaomi 17 Ultra - but it requires a USB 3.2-rated cable sold separately. The standard cable in the box does not unlock USB 3.2 speeds. Worth knowing before you plan to transfer 4K video files.

HyperOS 3 on Android 16 is a noticeable improvement over older Xiaomi builds. The interface is cleaner, system animations are smoother, and most pre-installed apps can be removed. Beebom's review flagged adware still present in the software and called for more UI polish in some areas - a consistent Xiaomi criticism that has not been fully resolved this generation. The 5-year OS update commitment is an improvement over the Xiaomi 15 Ultra's 4 years - but still trails Samsung's 7-year guarantee by two full Android versions.

The Camera System: LOFIC, Leica, and the World-First Mechanical Zoom

This is the phone's entire identity. Xiaomi and Leica's "Strategic Co-creation Model" means every optical component - lens design, coating, colour science, and sensor pairing - was developed together from the ground up rather than tuned after the fact. The result is a triple-camera system that covers 14mm to 100mm with complete optical quality across the entire range.

Camera Sensor Focal Length Key Detail
Main (Wide) 50MP Light Fusion 1050L, 1-inch, LOFIC 23mm (Leica Summilux) f/1.6, OIS, 6-stop IBIS
Ultrawide 50MP 14mm f/2.2, autofocus
Periscope Telephoto 200MP 75-100mm continuous optical zoom (3.2x-4.3x) f/2.6, OIS, mechanical zoom, three movable lens groups
Front Camera 50MP Wide Autofocus

LOFIC - Lateral Overflow Integration Capacitor - is new sensor technology debuting here. It prevents highlights from blowing out and shadows from crushing simultaneously by capturing significantly more light data at the hardware level. Xiaomi's own testing shows a full well capacity 6.3 times greater than the previous generation. What reviewers actually observed: natural, detailed night photography with dynamic range that competing phones with smaller sensors cannot match at the same level. 91mobiles described the LOFIC implementation as enabling "DSLR-like high-dynamic-range photos and especially video in challenging lighting." Beebom went further: "night shots from this phone are simply out of this world."

The 200MP periscope telephoto is where the MWC Best in Show award was earned. The system uses three lens groups - the second and third move independently to achieve true optical zoom across the 75mm to 100mm equivalent range. This means every focal length between 3.2x and 4.3x delivers full 200MP optical quality with no digital cropping involved. No other phone does this. Every other smartphone telephoto snaps between fixed zoom steps - 3x, 5x, 10x - and uses digital cropping to fill the gaps. The Xiaomi 17 Ultra lets you smoothly dial in exactly 3.7x, or 4.0x, or 4.2x, and get genuine optical resolution at each point. Gizbot's May 6 review called this "hardware you won't find on any other phone right now" - accurate as of today.

In practical photography terms, 91mobiles' reviewer found the camera system "one of the most capable smartphone camera systems available today." Beebom's verdict: the camera hardware is "so good that it will make you forget about professional DSLR and Mirrorless shooters." The multi-focal length versatility - covering 14mm landscape through to 100mm portrait - means the Xiaomi 17 Ultra handles every scenario from architecture to street to portrait without reaching for a second device.

The honest limitation is the maximum optical zoom reach. The 4.3x maximum puts the Xiaomi 17 Ultra behind the OPPO Find X9 Ultra's 10x native optical zoom and the Galaxy S26 Ultra's 5x periscope for long-distance subjects - concerts, wildlife, sports from the stands. Beyond 4.3x, the phone uses digital zoom which, while aided by the 200MP sensor's resolution, cannot match dedicated telephoto glass at 10x or beyond.

Photography Kit Pro: The Accessory That Changes Everything

The Photography Kit Pro - bundled free at launch, now ₹19,999 separately - includes a contoured grip, shutter button with half-press focus, command dial for manual exposure and ISO, zoom lever, and a 2,000mAh auxiliary battery with its own USB-C port. With the grip attached, using the Xiaomi 17 Ultra for photography no longer feels like using a phone. The physical shutter feedback, the two-handed grip, and the zoom lever create a camera-like experience that transforms the shooting workflow.

Battery life with the grip attached extends the phone's endurance meaningfully - reviewers consistently reported finishing full-day outdoor photography shoots at 80-90% of remaining power between the phone and the grip combined. The current limitation: the grip's USB-C port does not pass data - external microphones and SSDs require removing the grip. This is a genuine constraint for video creators who want to shoot with audio gear attached simultaneously.

Battery and Charging: 6000mAh With a Real-World Split

Battery Xiaomi 17 Ultra (India) Samsung Galaxy S26 Ultra
Capacity 6,000mAh silicon-carbon (India) | 6,800mAh (China only) 5,000mAh lithium-ion
Wired Charging 90W HyperCharge (PPS-compatible) 60W Super Fast Charging 3.0
Wireless Charging 50W HyperCharge wireless 25W
Reverse Wired Charging 22.5W Not confirmed
Charger in Box Yes - 90W (India) No (cable only)
Real-World Battery Life Full day heavy use, 1.5 days moderate use Full day most users

The 6,000mAh silicon-carbon battery in the India variant delivers genuine all-day endurance. 91mobiles' review confirmed the phone "comfortably lasted a full day of heavy use and stretched to a day and a half on moderate use." That is better real-world endurance than the Galaxy S26 Ultra's 5,000mAh lithium-ion cell, which Beebom tested at 7.5 hours average screen-on time.

Important note for India buyers: the China variant ships with a 6,800mAh cell. India gets a 6,000mAh version - an 800mAh reduction. Xiaomi made this change to comply with airline battery transport regulations for the higher-capacity Chinese variant. In daily use, most reviewers did not report this as a problem. But it is a spec gap worth knowing if you are comparing against the Chinese spec sheet.

The 90W wired HyperCharge now supports PPS-compatible adapters - standard third-party fast chargers work without needing Xiaomi's proprietary brick. The 90W charger is included in the box in India, which remains a meaningful value advantage over Samsung, which includes no charger with the Galaxy S26 Ultra. The 50W wireless charging is dramatically faster than Samsung's 25W wireless.

Who Should Buy the Xiaomi 17 Ultra?

Buy the Xiaomi 17 Ultra if photography is the primary reason you are spending this much money on a phone. The 1-inch LOFIC main sensor, the world-first mechanical continuous optical zoom telephoto, the Leica Summilux optics, and the 90W fast charging with the charger included in the box combine into a package that genuinely delivers on its camera-first promise. The IP68 plus IP69 dual certification and Dolby Vision display support are meaningful bonuses. If you can apply the HDFC or ICICI card discount, the ₹1,29,999 effective price makes the value proposition even stronger.

Do not buy the Xiaomi 17 Ultra if you need a stylus, rely on Samsung DeX for desktop productivity, or plan to keep the phone for more than 5 years and want guaranteed OS updates throughout. The Galaxy S26 Ultra at ₹1,18,990 is now ₹21,000 cheaper and wins on those specific fronts. Software polish - specifically the remaining adware in HyperOS 3 and occasional UI rough edges - is also a gap for buyers coming from clean software experiences.

What strikes me about the Xiaomi 17 Ultra after going through every serious review is that Beebom's summary captures it precisely: "an excellent camera phone to get, if that is where your priority lies." That qualifier - if that is where your priority lies - is doing a lot of work. If your priority is camera hardware, this phone leads 2026. If your priority is anything else, the field is more competitive than the spec sheet suggests.

iTechnoGlobe Verdict: 9.0 / 10
