Samsung Galaxy S26 vs Xiaomi 15

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

The 6.36-inch 1.5K LTPO OLED is sharp, vibrant, and incredibly bright at 3,200 nits peak (tested up to 3,593 nits HDR). Ultra-narrow 1.38mm bezels and high-frequency PWM dimming above 3,000Hz round out an excellent display package, though OLED smear at lower brightness is a noted concern.

• Peak brightness tested at 3,593 nits in HDR — among the brightest compact phone displays available
• Ultra-narrow 1.38mm bezels with excellent color accuracy in Original Color PRO profile
• OLED smear visible at lower brightness levels (0-70% range) — a recurring user complaint
