Between the OnePlus 12 and Poco F7 Ultra, the OnePlus 12 comes out ahead in pixel density and screen size, while the Poco F7 Ultra wins on antutu and wired charging. Overall, the OnePlus 12 scores 69.6 and the Poco F7 Ultra scores 70.4 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (69.6 vs 70.4). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the OnePlus 12 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are pixel density, screen size, battery capacity.
Pick the Poco F7 Ultra if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are antutu, wired charging, weight, among others.
Both ship with comparable ram, main camera, refresh rate, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
