The Galaxy S26 Ultra and Xiaomi 17 Ultra both give you a 6.9-inch display, but their strongest listed differences lie elsewhere. Samsung highlights a Privacy Display, while Xiaomi pairs a 6000 mAh battery with explicitly rated 90W wired and 50W wireless charging.

For a UAE buyer comparing the Samsung Galaxy S26 Ultra with the Xiaomi 17 Ultra, the choice largely hinges on travel zoom and charging habits. Weigh whether you value Samsung's on-screen privacy protections or Xiaomi's larger battery pack and dedicated high-resolution telephoto lens. Daily comfort with One UI 8.5 or HyperOS 3 matters more than a secondary spec sheet feature you rarely open.

When assessing the Samsung Galaxy S26 Ultra against the Xiaomi 17 Ultra, compare the storage tiers and regional configuration as carefully as the model name. Because both flagship variants listed here feature 16GB of RAM and 1TB of storage, verify memory tiers carefully when comparing retail offers. Keeping the exact 16GB/1TB SKU noted ensures quotes reflect an identical setup.

Specifications compared

The Samsung Galaxy S26 Ultra and Xiaomi 17 Ultra entries above describe documented catalog configurations rather than laboratory benchmarks. Xiaomi's 120 Hz display ceiling does not dictate sustained game frame rates, nor does its 90 W wired rating guarantee peak speed across an entire charge cycle. Use these figures to shortlist your priorities, then consider which focal length you shoot with most often.

Camera

Samsung assigns 200MP to its main camera alongside 50MP ultra-wide and telephoto lenses. Xiaomi places a 50MP sensor on its main and ultra-wide cameras, but steps up to a 200MP Leica APO telephoto with OIS. That placement matters: a high-resolution telephoto and a high-resolution primary lens serve very different photographic roles.

When evaluating the Galaxy S26 Ultra against the Xiaomi 17 Ultra camera setup, consider how you capture scenes across varying distances. Evaluate the final processed photograph from Samsung's 200MP primary sensor or Xiaomi's 200MP Leica telephoto rather than relying on the viewfinder. This focuses on how the 200MP wide and 200MP telephoto sensors actually render detail in your typical environments.

Battery and charging

Xiaomi lists a 6000mAh capacity with 90W wired, 50W wireless, and reverse wireless charging. Samsung records approximately 5000mAh with Super Fast wired and wireless charging without publishing specific wattage figures. While Xiaomi provides more numerical detail, battery capacity alone cannot determine total runtime under varied real-world use.

Gaming performance

Both devices feature the Snapdragon 8 Elite Gen 5 platform, with Samsung listing its custom "for Galaxy" variant. Sharing a chipset architecture does not guarantee identical sustained thermals. Check available graphical presets in your preferred titles, as software optimisation can constrain settings independently of hardware.

Demanding sessions, prolonged midday screen brightness, and mobile network handoffs will quickly influence power consumption and thermal stability on both 6.9-inch flagships. For the Samsung Galaxy S26 Ultra and Xiaomi 17 Ultra, no comparative thermal testing is documented here, so no heat-dissipation winner is claimed.

Software support

One UI 8.5 and HyperOS 3 both run on Android 16 across these devices. Anyone switching ecosystems should review local cloud backups, photo library sync, and work profile management. Neither manufacturer entry includes a documented, numerical OS update lifespan in this comparison table.

Advantages

Samsung Galaxy S26 Ultra

The Galaxy S26 Ultra stands out with its integrated Privacy Display feature and a 200MP high-resolution primary camera sensor.

Xiaomi 17 Ultra

Xiaomi provides a 200MP Leica APO telephoto lens, a larger 6000mAh battery, and clearly stated 90W wired and 50W wireless charging ratings.

Disadvantages

Samsung Galaxy S26 Ultra

Samsung lists an approximate 5000mAh capacity and omits precise charging wattages, offering less numerical certainty for charging-focused comparisons.

Xiaomi 17 Ultra

With its 6.9-inch display, the Xiaomi 17 Ultra shares Samsung's broad physical footprint rather than offering a smaller form factor.

Final buying verdict

Choose the Samsung Galaxy S26 Ultra if on-screen privacy filtering and One UI 8.5 are your main criteria. Choose the Xiaomi 17 Ultra if you want the dedicated 200MP telephoto lens, the 6000mAh battery capacity, and documented 90W fast charging.

Before finalising an order for either the Galaxy S26 Ultra or Xiaomi 17 Ultra, verify that the packaging denotes the official TDRA UAE specification rather than an unverified grey-market import. Confirm TDRA-approved UAE retail packaging for both the S26 Ultra and Xiaomi 17 Ultra against non-local market imports to guarantee network compatibility and warranty coverage.

Miles Telecom can confirm product details for your chosen configuration. Verify the exact 16GB/1TB capacity and official TDRA designation for either device to ensure warranty and network compatibility.
