Samsung’s new display tech makes the Galaxy S21 Ultra even more power efficient

It’s safe to say that OLED displays are the gold standard on smartphones these days. What you might not know is that some OLED panels are better than others, and the Galaxy S21 Ultra features what may well be the best one to date.

Well, best may be subjective in some ways — but the device’s display is definitely the most power efficient. In fact, Samsung developed a new ultra-low-power OLED display for the new phone, and it reduces energy consumption by up to 16%.

The way Samsung did this is a little technical. OLED displays in general don’t require a backlight like LCD screens. Instead, each individual pixel is made from an organic carbon-based material that lights up when electricity is applied. OLED displays are made up of a range of layers, which serve different purposes. The gist of the new OLED display tech is that Samsung found a way for electrons to flow faster between these layers, while at the same time creating a brighter light.

The power-consumption savings will be put to good use, as 5G phones can take up a little more energy than non-5G phones, while other things, like more powerful chipsets, can also hoard power.

It’s important to note that the new display tech is only available on the Galaxy S21 Ultra — not the standard Galaxy S21 and Galaxy S21+. All three of the devices offer up to a 120Hz refresh rate, however, the Galaxy S21 Ultra has a 1,440p resolution. And while the standard Galaxy S21 and S21+ have refresh rates that vary between 48Hz and 120Hz, the Galaxy S21 Ultra can go as low as 10Hz, which also helps save on energy consumption.

Samsung has been a leader in display tech for a long time, and it looks like that will continue well into the future. The company says that it holds 5,000 patents that involve the use of organic materials for displays. Hopefully, this new tech will be brought to lower-end phones over the next few years, or at least to the entire Galaxy S22 series next year.

As we get closer to the launch of the Galaxy Z Flip 5, details have started surfacing more regularly. In February, we learned that the cover display will be much larger than the one found on the Galaxy Z Flip 4. Now, rumors seem to suggest that the new foldable will be the first of its kind sporting two discrete cover displays.

According to renders shared in a recent video by mobile insider SuperRoader, the Galaxy Z Flip 5's dual cover screens will greatly differentiate the foldable from the rest of its kind. The two screens are vastly different in size, and seem to serve two distinct functions.

Samsung’s Galaxy S23 is here, and it's quickly become one of the best phones you can buy in 2023. For $800, you’re getting a small but mighty phone with Snapdragon 8 Gen 2 for Galaxy chipset, long-lasting battery life, and a powerful triple lens camera system with a 50-megapixel main shooter.

But how does one of the best Android phones stack up against Apple’s smallest flagship, the iPhone 14 Pro? It has just as many cameras as the Galaxy S23, a powerful 48MP main camera, and costs $200 more than Samsung's handset.

Nothing Phone 1 with Glyph lights active.

The Nothing Phone 1 made its debut in July 2022, and it had a reasonable amount of hype behind it due to the involvement of Carl Pei, a co-founder of OnePlus. It was a quirky phone due to the unique light show on the back that makes it stand out from the competition, but on the software front, it’s very similar to other Android phones out there. It received mixed reviews, though the consensus leaned more on the positive side.

This year, we’re expecting the Nothing Phone 2, as confirmed by Pei in January during MWC 2023. Here’s everything we know so far about the Nothing Phone 2!
