Adaptive refresh rate saves 22% battery life on Note 20s


The autonomy of the battery it has often been a pending issue for the Korean brand. Although over the years it has improved considerably, if we had to attribute a weak point of the Samsung’s top of the range is the life of your battery. Now the brand has hit the nail on the head to extend autonomy. And it is not in the battery itself.

Last week, Samsung revealed its new Galaxy Note 20 lineup, and the higher-end model comes with a 120Hz display. A higher refresh rate allows smoother browsing to be enjoyed whether using the S-Pen or playing mobile games. However, as users working with high refresh rates will know, this has a direct impact on the battery life of phones.

To combat this, Samsung Display announced that its new OLED displays They boast of “adaptive frequency” technology, which is also available to other manufacturers who want to apply it to their phones. This time we are facing a type of panel that is different from what we have seen before, since they allow us to enjoy higher refresh rates, but without this having an impact on the autonomy Of the device.

Improving the mobile battery from the screen

This new screen, which debuts in the Galaxy Note 20 Ultra 5G, can reach the 120Hz when high refresh rate speeds are needed for games but it automatically drops to 60Hz when, for example, we run video playback, at 30Hz when messaging, or as low as 10Hz when displaying a still image.

At the slowest setting, Samsung claims that it can use only 60 percent of the power normally required, while other displays cannot adjust without starting to flicker. Samsung Display Vice President of Mobile Display Planning Ho-Jung Lee said in a statement: “This adaptive rate display technology is expected to greatly enhance the user experience by calibrating refresh rates to the requirements of a specific application and therefore allocating available power more precisely«.

In general, the company has conducted its own tests to determine how, just with this adjustment of the refresh rate, it can save up to a 22% battery compared to other displays. However, it is not clear if this new technology is limited to a specified configuration.

Luckily soon we will be able to test the mobile and with it the autonomy of the Note 20 Ultra in all possible configurations.
