While having a high refresh rate can certainly result in an elevated viewing experience, there is a trade-off involved. A higher refresh rate is more taxing on battery life, which is the reason why mobile vendors provide users with an option to keep it to 60Hz when not needed. Samsung’s latest flagship also comes with a buttery smooth display and if you are wondering about the Galaxy S20 Ultra 120Hz battery drain, Tom’s Guide recently tested out the device to find the same.

Samsung’s premium flagship packs in a huge 5000mAh battery, which means it should be able to last a long time. The outlet tested the device four times and the process involved continuous web browsing at a screen brightness of 150 nits. Two of the tests were conducted with the refresh rate at 60Hz and two at a higher rate to figure out the extent of the Galaxy S20 Ultra 120Hz battery drain.
