Samsung Galaxy S25 Ultra
The 6.9-inch Dynamic AMOLED 2X display with 2600 nit peak brightness and anti-reflective coating is universally praised as the best smartphone display available.
Xiaomi 15 Pro
The 6.73-inch 2K LTPO AMOLED is a technical marvel, hitting 3,200 nits peak brightness while consuming 24% less power than the Xiaomi 14 Pro's display. The 1920Hz PWM dimming reduces eye strain, though some users report OLED smear at low brightness levels.
Samsung Galaxy S25 Ultra
The quad camera system features an improved 200MP main sensor, 50MP ultrawide, 10MP 3x telephoto, and 50MP 5x periscope. Galaxy AI enhances post-processing significantly.
Xiaomi 15 Pro
The triple 50MP Leica Summilux system delivers solid results with a standout 5x periscope telephoto. The main sensor with f/1.44 aperture handles most scenarios well, and AI Zoom makes 20x digital shots usable. However, the ultrawide is the clear weak link, and the system can't quite match the Vivo X200 Pro's imaging prowess.
