Reports say that the OLED screen on Samsung's latest Galaxy S21 Ultra device uses less power than the one on last year's S20 Ultra and Note20 Ultra smartphones. According to AnandTech, tests revealed that when faced with dimmer situations, the S21 Ultra screen consumed more than expected power, but at full brightness on a white screen test, turned out to be up to 31% more efficient than the one on the S20 Ultra. Reports say the better performance is thanks to a new OLED emitter used on the latest flagship device, that was launched on Jan 14 at a price of ₹1,05,999 in India.
