Samsung Galaxy Z Fold 6 vs Xiaomi 15

Samsung Galaxy Z Fold 6

The inner 7.6-inch display is gorgeous but the narrow cover screen divides opinion.

• The inner display is beautiful — bright, smooth, and the extra screen real estate transforms productivity tasks.
• The cover screen at 6.3 inches is usable but still feels cramped compared to regular phones — typing is a challenge.

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

Samsung Galaxy Z Fold 6

Capable cameras but not flagship-tier, which stings at this price point.

• Photos are good by any standard, but when you're paying $1,899, 'good' feels insufficient compared to the S24 Ultra's camera.
• The 3x telephoto is fine but the lack of a periscope zoom lens feels like a cost-cutting measure.

Xiaomi 15

The triple 50MP Leica system shines with its main sensor and improved 2.6x telephoto, earning a DxOMark score of 146. Leica color profiles produce natural, pleasing images with excellent dynamic range. The ultrawide camera is the clear weakness, with noticeably more noise in low light and no autofocus.

• 50MP main Leica Summilux camera delivers excellent photo quality with natural colors and strong dynamic range
• 2.6x optical telephoto is a meaningful upgrade over the Xiaomi 14 — sharp and versatile
• Ultrawide camera is the weakest link — subpar quality, no autofocus, noticeably more noise in low light
• DxOMark camera score of 146 — good but not class-leading among 2025 flagships
