Samsung Galaxy S26+ vs Xiaomi 15

Samsung Galaxy S26+

The 6.7-inch QHD+ Dynamic AMOLED 2X panel with 1-120Hz adaptive refresh rate is familiar territory — essentially the same excellent display as the S25+. No Privacy Display here; that remains an Ultra exclusive.

• The 6.7-inch QHD+ panel continues to be one of the best in its class with vibrant colors and excellent brightness
• No Privacy Display on the S26+ is a real missed opportunity — the best S26 feature is locked to the Ultra

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
