Galaxy S20 Ultra: This is how much the 120 Hz mode affect the battery life

120-Hz displays Galaxy S20

120 Hz display mode is the major new feature in 2020 smartphones. The Samsung Galaxy S20 series has such a display installed, but you can only enjoy the high refresh rate with FullHD +.

But how much does the twice as high refresh rate affect the smartphone’s battery compared to the normal 60 Hz? Phonebuff tried it out on the Samsung Galaxy S20 Ultra.

For this purpose, the Samsung Galaxy S20 Ultra was sent twice through the exact test course, once with 60 Hz and then once with 120 Hz. And in the end, the result comes, which is a little surprising.

Galaxy S20 Ultra: This is how much the 120 Hz mode affect the battery life

It is clear to everyone that the display consumes more battery with a 120 Hz rate. With the screen-on-time, you get 10:24 hours at 60 Hz and 9:35 hours at 120 Hz. At the end of the test, the difference is 14 percent of the battery has left on the device that has 60 Hz while the 120 Hz device turns off.

In the end, it means that under full load at 120 Hz you have almost 1 hour less screen-on-time compared to 60 Hz, which is not the big difference that we expected.
