Xiaomi - Poco F7 Ultra vs Xiaomi 15

These two are nearly even on the Mars Score (69.2 vs 69.8). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the Poco F7 Ultra if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are wired charging, screen size. The single most decisive one: Wired charging — 33.33% more. 120 W vs 90 W.

Pick the Xiaomi 15 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are weight, pixel density, battery capacity, among others. The single most decisive one: Weight — 20.00 g less. 192 vs 212.

Both ship with comparable ram, main camera, refresh rate, so those specs do not separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
