Samsung Galaxy S21 Ultra Uses New OLED Technology for Longer Battery Life

Samsung's industry-leading displays are second to none. With the Galaxy S21 Ultra, they showcased their most cutting-edge screen yet. The new Ultra display can refresh at 120Hz, while set at the full QHD+ resolution. All while consuming less power than ever. Here’s how they did it.

Samsung Display, the world’s largest manufacturer of displays, explained in a press release that their newly-developed OLED screens used in Samsung Galaxy S21 Ultra, are more efficient and brighter. Thanks to new organic materials used to fashion these next-gen panels, the power consumption is cut down by 16%. 

“Samsung Display has developed new organic materials to increase the moving speed of electrons in the organic material layer, thereby greatly improving luminous efficiency,” the press release noted. At 1500 nits of peak brightness, the Galaxy S21 Ultra’s is Samsung's brightest display. 

What it essentially means is that these low-power OLED panels on Samsung Galaxy S21 Ultra shine brighter while being lighter on the resources. 

In the case of last year’s S20 Ultra, the dynamic 120Hz mode, even with the resolution capped at 1080P, shaved as much as three hours off the battery life. If not for the new OLED panel, the 5G modem, QHD+ resolution at 120Hz, and increased brightness would make the battery drain more severe.

It remains to be seen how much of a difference this 16% improvement in efficiency makes in the real world. Currently, the only Samsung product to feature this tech is the Galaxy S21 Ultra, which won’t hit stores until January 29, 2021. But you can expect more OLED screens to switch to these low-power panels in the near future.
