Which should you buy?

Pick the Galaxy S25 Ultra 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 main camera, screen size, battery capacity.
Pick the Galaxy S26+ if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are weight, pixel density, antutu.
Both ship with comparable ram, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
