Which should you buy?
The OnePlus 13 edges ahead on the Mars Score (69.6 vs 73.8), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The OnePlus 12 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the OnePlus 13 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 ram, antutu, battery capacity, among others.
Both ship with comparable main camera, screen size, 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.
