Samsung Galaxy S26 vs Xiaomi 15 Ultra

Samsung Galaxy S26

The 6.3-inch FHD+ Dynamic AMOLED 2X display with 1-120Hz adaptive refresh rate carries over from the S25. It remains a sharp, vibrant panel for its compact size. No Privacy Display — that's Ultra-only.

• The 6.3-inch compact form factor remains the S26's biggest strength — it's one of the few true compact flagships available in 2026
• FHD+ resolution feels like a compromise at $900 — the S26+ and Ultra both get QHD+ panels

Xiaomi 15 Ultra

A stunning 6.73-inch 2K LTPO AMOLED with 120Hz, 3,200 nits peak brightness, and Dolby Vision support.

• 3,200 nits peak brightness is the highest of any smartphone tested, with excellent outdoor visibility and HDR performance
• 2K resolution with 120Hz LTPO delivers incredibly sharp, smooth visuals for gaming and media consumption

Samsung Galaxy S26

The S26 adopts more angular, Ultra-like corners for a unified family design. The Armor Aluminum frame and Gorilla Glass Victus 2 provide solid durability. At ~7.3mm and ~162g, it's pocketable and lightweight.
