Which should you buy?

Pick the OnePlus 12 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 screen size.
Pick the OnePlus 14 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.
