Poco F7 Ultra vs Xiaomi 15 Ultra

Poco F7 Ultra

The 6.67-inch QHD+ OLED is one of the brightest panels on the market at 3,200 nits peak, with sharp 1440x3200 resolution and 120Hz refresh rate. GSMArena noted it was the third-brightest phone they had tested at the time. The lack of LTPO technology is the main shortcoming at this tier.

• QHD+ OLED at 3,200 nits peak brightness — third-brightest phone GSMArena had tested at review time
• Sharp 1440x3200 resolution at 120Hz with excellent viewing angles and color accuracy
• Not an LTPO panel — cannot scale down to 1Hz like true flagship displays, affecting battery efficiency

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 F7 Ultra

The Snapdragon 8 Elite with VisionBoost D7 GPU delivers raw benchmark scores that exceed even the Xiaomi 15 Ultra in some tests, with an AnTuTu score around 2.63 million. Lightning-fast OS navigation and multitasking. However, thermal management is aggressive — the aluminum frame reaches 45°C+ during extended gaming.

• Snapdragon 8 Elite with VisionBoost D7 GPU — AnTuTu ~2.63 million, exceeding even Xiaomi 15 Ultra in some benchmarks
• Handles any game at maximum graphical settings with lightning-fast app launches and multitasking
• Thermal management is aggressive — frame reaches 45°C+ during extended gaming at under 20°C ambient

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 F7 Ultra

The first Poco phone with a telephoto camera (50MP, 2.5x optical zoom) is a landmark addition. The 50MP main sensor delivers nicely detailed images with excellent dynamic range, and Creative Bloq called it potentially "the best value camera phone of 2025." However, the 32MP ultrawide delivers muddy results, the selfie camera lacks autofocus, and video recording options are limited.

• First Poco phone with a telephoto (50MP, 2.5x optical) — close-focusing enables excellent macro-style shots
• 50MP main sensor delivers nicely detailed images — "potentially even better than Samsung S25 Ultra" in certain scenarios
• 32MP ultrawide delivers comparatively muddy and flat results versus the main sensor
• Camera system described as "inconsistent" — selfie lacks autofocus, video tops out at 4K@60fps

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
