Samsung Galaxy Z Fold 6 vs Xiaomi 15 Ultra

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 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 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 Ultra

The crown jewel — a triple Leica camera system with a 1-inch main sensor, 200MP telephoto, and 50MP ultrawide that redefines smartphone photography.

• The 1-inch main sensor captures more light and detail than any competing smartphone camera — photos have a depth and quality that approaches dedicated cameras
• 200MP telephoto with 4.3x optical zoom produces incredibly detailed zoom shots that rival the Galaxy S25 Ultra's 5x periscope
• Leica color science produces warm, film-like tones with natural skin rendering that photographers love
• Video stabilization is the best on any Android phone, though color consistency and dynamic range in video still trail the iPhone
