How does the 120 Hz screen of the Samsung Galaxy S20 Ultra affect the battery?


Galaxy S20 Ultra, which is one of the devices introduced by Samsung at the UNPACKED event, comes with 120 Hz display support, unlike standard smartphones. So how does the 120 Hz supported display affect the battery? Let’s look for an answer to this question together.

One of Samsung’s new flagship devices, Galaxy S20 Ultra promises a very smooth user experience with its 120 Hz screen refresh rate. This value, which means a screen that is renewed 120 times per second, is quite high compared to the refresh rate of many smartphones in the market today. This feature makes the phone’s interface much more fluid, but also significantly increases battery usage.

Samsung will have taken into account this increase in battery usage, with devices coming out of the box at 60 Hz screen refresh rate. The screen refresh rate can then be increased to 120 Hz depending on the user preference. To learn how to do this, you can check out our news, which you can reach by clicking here. Having discussed how the battery of the device was affected after activating this feature, phoneArena put the Galaxy S20 Ultra into a battery test. Let’s take a closer look at the results of the test.

How is the Galaxy S20 Ultra’s 5,000 mAh battery affected by 120 Hz?
The phoneArena team stated that when they take the screen of the Galaxy S20 Ultra to 120 Hz, they see a big difference in the fluency of the device, and this support will be especially useful for the players. Of course, for this, games must also have 120 Hz support.

In a battery test with an Galaxy S20 Ultra with Exynos 990 processor, it was stated that the ‘optimized battery mode’ is active and the screen resolution is 1080p. You can check the battery discharge times of phones including iPhone 11 Pro Max as well as Samsung’s popular devices below.

Samsung Galaxy S20 Ultra / 60 Hz: 12 hours 23 minutes
Samsung Galaxy S20 Ultra / 120 Hz: 10 hours 2 minutes
Samsung Galaxy Note10 Plus / 60 Hz: 11 hours 37 minutes
Samsung Galaxy S10 Plus / 60 Hz: 10 hours 33 minutes
Apple iPhone 11 Pro Max / 60 Hz: 12 hours 53 minutes

Looking at the data obtained from the battery tests, the screen, taken from 60 Hz to 120 Hz, significantly increases the use of the battery. Samsung Galaxy S20 Ultra, which is among the phones that offer the best battery life in the list when it comes to 60 Hz screens, unfortunately cannot deliver the same performance at 120 Hz.

Of course, all this will be shaped by users’ preferences. In other words, while fluency is at the forefront for some users, some users will think that battery life is more important. For this reason, the difference in battery life may be insignificant for some people. Do you think this value is a difference that can be sacrificed for fluency?
