Samsung’s Galaxy S21 Ultra is first with new power efficient OLED display Share this story Photo by Vjeran Pavic / The Verge Samsung’s latest flagship, the Galaxy S21 Ultra, is its first phone to feature Samsung Display’s new power-efficient OLED panels. In a press release, Samsung says the new display consumes 16 percent less power thanks to a “just-developed organic material” that means “electrons flow faster and more easily across the display’s organic layer.” “In other words,” Samsung explains, the technology means its “OLED panels can create brighter light while consuming less power, which improves the battery lifetime.” A smartphone’s display is typically one of its most power-hungry components, so efficiency gains here can have a big impact on the overall battery life of the device. In our review, we remarked that the S21 Ultra has excellent battery life that lasts “beyond a full day.”
