Pick the Zenfone 11 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 front camera, wired charging, battery capacity, among others.
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, among others.
Both ship with comparable main camera, 5g support, water resistance, so those specs don't separate the two — focus on the differences below.
