Xiaomi 15 Pro vs Xiaomi 15 Ultra

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.

• 3,200 nits peak brightness with 24% lower power consumption than the predecessor — outstanding efficiency
• 2K resolution (2670x1200) with 120Hz LTPO and 1920Hz PWM dimming for reduced eye strain
• Reports of OLED smear/ghosting at lower brightness levels when scrolling dark content

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

Xiaomi 15 Pro

The Snapdragon 8 Elite (3nm) delivers a 44% single-core improvement over the previous generation and manages thermals better than most competitors. NotebookCheck awarded a 99% application performance score, placing it among the fastest phones available.

• Snapdragon 8 Elite achieves Geekbench 6 single-core of 3,157 — a 44.4% leap over Snapdragon 8 Gen 3
• Better thermal management and sustained performance than competitors like the Oppo Find X8 Pro
• Some throttling under prolonged heavy gaming loads, though managed better than peers

Xiaomi 15 Ultra

Snapdragon 8 Elite with 16GB RAM delivers the fastest Android performance available with excellent thermal management.

• Snapdragon 8 Elite with 16GB RAM makes this one of the fastest phones tested — no app or game can slow it down
• Liquid cooling system keeps sustained performance high with minimal throttling during extended gaming sessions
• 16GB RAM ensures smooth multitasking with dozens of apps in memory and efficient AI processing

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.

• 5x periscope telephoto (120mm) delivers sharp, detailed results up to 10x — AI Zoom usable at 20x
• Main 50MP sensor with f/1.44 aperture and Leica color science produces pleasing, natural-looking images
• Ultrawide camera (50MP JN1) is the weakest lens — frequently criticized by users as noticeably below main and telephoto quality
• Camera scored 82% on NotebookCheck — the lowest individual category score, behind the Vivo X200 Pro

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
