Which should you buy?
The OnePlus 15 is the clear pick on raw spec strength, leading by 13.8 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the ThinkPhone 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 weight, refresh rate.
Pick the OnePlus 15 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 wireless charging, antutu, ram, among others.
Both ship with comparable main camera, 5g support, front camera, so those specs don't separate the two — focus on the differences below.
Bottom line: the OnePlus 15 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
