Mumbai, March 1: The flagship smartphone market in 2026 has reached new heights with the introduction of the Xiaomi 17 Ultra and the Samsung Galaxy S26 Ultra, two of the most feature-rich devices available. Both brands aim to redefine the Ultra experience, but they adopt distinct approaches in design, imaging systems, performance, and software. Let’s analyze which device might be worth your investment.
Design and Build
Xiaomi has introduced a flat display for the first time in its Ultra series with the 17 Ultra. This model features a 6.9-inch display with ultra-thin bezels and a sleek, linear design. The camera module has been minimized and repositioned higher for better balance. At just 8.29mm thick, it is the slimmest Ultra model Xiaomi has ever produced.
Samsung has made the Galaxy S26 Ultra even slimmer than its predecessors, measuring only 7.9mm. It also sports a 6.9-inch flat screen and a Privacy Display, which restricts viewing angles to enhance privacy in public settings.
Both devices feel premium and are relatively lightweight for their category, but Samsung has a slight advantage due to its slimmer profile and the added practicality of the Privacy Display.
Display
The Xiaomi 17 Ultra features a 12-bit M10 OLED LTPO screen that can reach peak brightness levels of up to 3500 nits, making it the brightest among flagship smartphones. It incorporates HyperRGB TECHNOLOGY, delivering 2K clarity while consuming less power than standard 1.5K displays. The screen supports HDR10+ and Dolby Vision, protected by Xiaomi Shield Glass 3.0.
In contrast, the Galaxy S26 Ultra is equipped with a 10-bit Dynamic AMOLED display that supports adaptive refresh rates from 1-120Hz, HDR10+, and Gorilla Armor 2 protection. While it offers excellent visuals, it does not match the brightness and efficiency of Xiaomi’s display.
Xiaomi clearly leads in display performance with its brighter and more energy-efficient screen.
Performance
Both Xiaomi and Samsung utilize the Snapdragon 8 Elite Gen 5 chipset, but Samsung’s version is customized specifically for Galaxy devices, enhancing gaming, AI performance, and power efficiency. The Galaxy S26 Ultra comes with either 12GB or 16GB of LPDDR5x RAM and storage options of 256GB, 512GB, or 1TB UFS 4.1. It features the largest Vapor Chamber Samsung has ever made, improving heat dissipation for consistent performance during demanding tasks.
Xiaomi’s 17 Ultra is equipped with 16GB of LPDDR5x RAM and offers 512GB or 1TB of UFS 4.1 storage. It includes the Xiaomi 3D Dual-Channel IceLoop cooling system, which enhances thermal conductivity by 50% compared to previous models, ensuring sustained performance during intensive gaming and multitasking.
Both devices offer top-tier performance, making daily usage smooth and responsive regardless of your choice.
Software
The Xiaomi 17 Ultra ships with HyperOS 3.0 based on Android 16, providing a clean user experience but lacking significant AI features. Xiaomi does not match Samsung’s commitment to long-term software support.
Samsung prioritizes software with the Galaxy S26 Ultra, which runs Android 15 with One UI 8.5 and promises seven generations of Android updates along with seven years of security patches. It also introduces advanced AI features like Now Nudge for contextual suggestions and Now Brief for real-time summaries, making the device smarter and more intuitive.
Samsung excels in software innovation and long-term support, making it the better option for those who value longevity.
Cameras
The Xiaomi 17 Ultra features a camera system developed in collaboration with Leica, focusing on professional-grade photography. It includes a 50MP Leica 1-inch Ultra Dynamic Camera powered by the Light Fusion 1050L sensor, enhancing dynamic range and detail in challenging lighting. The 200MP Leica telephoto camera offers true optical zoom between 75mm and 100mm without digital cropping. The setup also includes a 50MP ultra-wide camera with a 115° field of view and macro capabilities, with Leica APO certification for sharper, more color-accurate images.
Xiaomi also provides optional Photography Kits for enthusiasts, including a grip with physical buttons and magnetic charging, with a Pro kit offering a larger battery and additional controls.
Samsung’s Galaxy S26 Ultra features a versatile quad-camera system, with a 200MP main sensor designed for low-light performance, a 50MP ultra-wide sensor, and two telephoto lenses: a 10MP 3x optical zoom and a 50MP periscope lens with 5x optical zoom, supporting up to 100x Space Zoom. Samsung enhances its Nightography Video for clearer low-light videos and improved stabilization for smoother handheld recording.
Xiaomi excels in still photography, while Samsung shines in video performance and low-light conditions.
Battery
The Xiaomi 17 Ultra boasts a 6000mAh battery with support for 90W wired charging, 50W wireless charging, and Programmable Power Supply (PPS) for optimized charging speeds.
Samsung’s Galaxy S26 Ultra has a smaller 5000mAh battery, featuring Super Fast Charging 3.0, which can charge the phone to 75% in just 30 minutes with its 60W charger. It also supports 25W Qi2 wireless charging and reverse wireless charging.
Xiaomi leads in this category with a higher capacity and faster charging options.
Which Ultra Should You Choose?
The Xiaomi 17 Ultra stands out for its brighter display, larger battery, and Leica-powered camera system, making it ideal for users who prioritize cutting-edge photography and hardware performance.
The Samsung Galaxy S26 Ultra excels in AI features, long-term software support, and low-light video performance, making it better suited for those who want a device that remains relevant for years and integrates advanced AI into daily use.
Both smartphones are exceptional in their own right, but the choice ultimately depends on whether you value photography (Xiaomi) or software and AI (Samsung).
