Poco X7 Pro vs Xiaomi 15 Ultra

Poco X7 Pro

The 6.67-inch AMOLED display punches well above its price class with 1220x2712 resolution, 120Hz refresh, 12-bit color depth, and an astounding 3,200 nits peak brightness. Dolby Vision and HDR10+ support make it excellent for media consumption.

• 3,200 nits peak brightness with Dolby Vision and HDR10+ — flagship-level at a budget price
• 1220x2712 resolution at 120Hz with 12-bit color depth — sharper than most phones in its class
• No LTPO means limited refresh rate granularity — either 60Hz or 120Hz

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

Poco X7 Pro

The Dimensity 8400-Ultra is the fastest mid-range chipset of 2025, rivaling the Snapdragon 8s Gen 3. Gaming performance is exceptional — PUBG runs at 118fps with 100% smoothness, and LiquidCool 4.0 vapor chamber cooling helps sustain performance during extended sessions.

• Dimensity 8400-Ultra scores ~1.83 million on AnTuTu — fastest in its price class by a significant margin
• PUBG at 118fps average with 100% smoothness — best gaming experience under $400
• 8GB RAM variant has aggressive RAM management — apps killed in background causing missed notifications

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

Poco X7 Pro

The 50MP main camera with Sony IMX882 delivers good daylight photos with faithful colors and wide dynamic range. The 2x in-sensor zoom works well. However, the 8MP ultrawide is significantly weaker with muddy results, and the 20MP selfie camera is particularly poor — effectively upscaled from 5MP.

• 50MP main sensor delivers good detail, low noise, and faithful colors in daylight conditions
• 2x in-sensor zoom is a useful upgrade from the predecessor — surprisingly capable
• 8MP ultrawide delivers significantly weaker results — low detail and muddy output
• 20MP selfie camera is effectively upscaled from 5MP — one of the worst at any price point

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
