The screens of our mobile phones increasingly have more spectacular features, one of which is creating a trend in recent months is that of the screen Hz. The higher the refresh rate, the smoother the movements. Now we have mobiles with screens up to 120Hz , and this video shows us how much more they can consume.
The increase in battery size of many premium or high mid-range mobiles has also occurred as a result of the increase in the refresh rate of phones on their screens, something that traditionally is enough reason to increase energy consumption .
Samsung Galaxy S20 Ultra: 120Hz vs. 60Hz
In the comparison that we echo today we can see what is the real difference between the consumption of a phone with a 120Hz screen and a 60Hz screen. In both cases it is the same screen of the Samsung Galaxy S20 Ultra, although with the different refresh modes activated. The idea is that both phones perform the same tasks with different refresh rates, in order to check how the same tasks are affected by twice the refresh rate in one of these models.
And in this PhoneBuff video it is quite curious to see that the difference between the two modes is not as great as would be expected. Because the moment the model with a 120Hz refresh rate runs out of battery, the S20 Ultra with 60Hz still has 14% available, probably among other things because of the lower refresh rate. But in any case it does not seem a difference in power consumption. During the test several apps and games have been run at the same time, and of course, the highest refresh rate has had an impact on the battery, but not as much as would be expected.
In the test meridian while the 60Hz model still had 50% of the battery, the Sasmung Galaxuy S20 Ultra had 42%. Therefore, with the passing of the test the differences have been increasing between both phones, until reaching that difference of 14 points at the end of the test. Therefore, yes, as expected, the screen with more Hz consumes more battery and makes the phone turn off sooner, but it is not as much of a difference as one would expect. So it seems like it would be worth having that greater screen fluidity despite sacrificing some autonomy, just a little.
