The Samsung Galaxy S20 series and the Galaxy Note 20 Ultra have a 120Hz refresh rate screen. But they achieve this high rate of renewal in very different ways. These phones use Super AMOLED display technology. But you should also know that the Galaxy Note 20 Ultra uses an Lplo backplane. It can achieve a variable rate of renewal and has a higher energy efficiency. In actual use, Sammobile learned that the Galaxy Note 20 Ultra is “more elegant” than the S20 series in 120Hz processing.

Whether it is a Galaxy S20, Galaxy S20 + or Galaxy S20 Ultra, when the phone battery power drops to 5%, the phone will automatically switch from 120Hz to 60Hz. Similarly, if the material reaches a certain temperature, it will drop to 60Hz. This is done to prevent the battery from running out and overheating. But the same situation does not fully apply to the Samsung Galaxy Note 20 Ultra and the 120Hz mode.
Samsung uses the aforementioned LTPO energy efficiency improvements. If the user sets the Samsung Galaxy Note 20 Ultra to run at a refresh rate of 120Hz, even after the battery drops to a certain level, the phone will not automatically return to 60Hz. This could be done manually by the user. The refresh rate continues to run until the user changes the setting or until the phone reaches a certain temperature.
The Samsung Galaxy Note 20 Ultra, like the Galaxy S20 series, also has a temperature protection mechanism. Prevents the phone from overheating. A lower refresh rate will help reduce the temperature. However, compared to the Galaxy S20 series, the Samsung Galaxy Note 20 Ultra seems to be able to continue using 120Hz at slightly higher temperatures.
Sammobile tested the 120Hz display mode on the Galaxy S20 Ultra and Galaxy Note 20 Ultra to determine how high a temperature it can reach before dropping to 60Hz. The result is: Once the first reaches 40 degrees Celsius, it will automatically change from 120Hz to 60Hz. The Galaxy Note 20 Ultra does not change at 60Hz until it reaches 43 degrees Celsius or higher.
Overall, for the Galaxy Note 20 Ultra, 120Hz does not seem to be a problem at higher temperatures. Although it is only a few degrees Celsius, it is better than nothing. In addition, the phone will not return to 60Hz when the battery is low.
