Why is the 120Hz refresh rate on Galaxy S20 display only for Full HD + resolution?

Tram Ho

The smartphone industry seems to be transitioning from the megapixel war to the endless race for higher and higher screen refresh rates. The latest rival on this track is Samsung, when the Korean giant is said to be equipped with a screen with a very high frequency of scanning on the upcoming Galaxy S20.

Rumors have it that the Galaxy S20 will have an AMOLED 120Hz screen. The evidence of this rumor is a hidden menu in the One UI 2.0 Beta interface, showing that users can switch between different scan frequencies, such as 60Hz and 120Hz, either manually or automatically.

However, users will have to accept the trade-off, when in ultra-smooth screen mode with high scan frequency, the screen resolution will no longer be at its maximum. The famous Ice Universe leaker emphasized that Samsung has removed the WQHD + resolution option at 120Hz on the Galaxy S20 series. So in fact, the 120Hz refresh rate will only work in Full HD + resolution only.

However, it was Ice Universe who previously “confirmed” the 120Hz mode on the Galaxy S20 will still work with high-resolution screens. Anyway, maybe the latest information this leaker has changed has changed.

Ice Universe’s tweet about Galaxy S20 users will have to trade between 120Hz screen and high resolution.

While this may disappoint you a bit, first learn about the benefits of a 120Hz screen and you may find Samsung limiting the resolution to this screen mode is a step away. how smart.

120Hz: better than 90Hz, 2 times faster than 60Hz

Of course, the 120Hz screen will be smoother than the 90Hz screen on 2019 flagships like Google Pixel 4 or OnePlus 7 Pro. With such a high refresh rate, the content displayed on the screen will be refreshed 120 times per second, twice as fast as Samsung’s flagships last year while still using the 60Hz screen.

This means that it will give users a smoother UI navigation experience, images will be less likely to break when playing high-speed 3D games, and the overall experience of smartphone users will be. markedly faster.

While not everyone recognizes these differences when compared to a 90Hz screen, it’s clear that equipping this display is a huge step forward for this year’s flagship Samsung.

The minus point is unfortunate but mandatory for Galaxy S20

While the 120Hz screen is definitely a welcome upgrade for users, it also has an unavoidable minus point: battery life.

Rumors suggest that the Galaxy S20 Ultra will have the largest battery, up to 5,000 mAh, a significant increase over the 4,300 mAh battery block on the Galaxy Note 10 Plus and the 4,100 mAh battery on the Galaxy S10 Plus. However, the large battery is not necessarily enough for the screen with a refresh rate of up to 120Hz.

Battery consumption is a big problem for smartphones with screens with high refresh rates. An Android Authority test shows that the battery life of the OnePlus 7 Pro is significantly reduced when switching from a regular 60Hz screen to a 90Hz screen.

That’s why devices like Google Pixel 4 switch between 90Hz and 60Hz displays to reduce battery drain. Tests show that, despite the larger battery, the screen brightness of Pixel 4 XL will only be equivalent to Pixel 4 when switched to 90Hz mode.

Users will be forced to choose between high frequency and high resolution on the Galaxy S20 screen.

Perhaps this is also why Samsung offers adaptive screen mode when switching between different screen scan frequencies, similar to how Google and OnePlus do. This is especially necessary when rumored, the Galaxy S20 and S20 Plus will have a smaller battery capacity than the S20 Ultra.

WQHD + resolution itself (with a total of 3,686,400 pixels on the screen) consumes a large amount of processing power as well as battery life, if the device is subjected to an additional scan frequency of up to 120Hz will The more the duration of use becomes shorter. Meanwhile, with Full HD + resolution (with 2,073,600 pixels on the screen), processing capacity and battery life will be significantly reduced.

So far, only Asus ROG Phone 2 is the only phone with an AMOLED screen with 120Hz. Even when equipped with a large battery pack of up to 6,000 mAh, this device only has the highest 1080p resolution when in 120Hz screen mode.

In the gaming world, high resolution screens and high refresh rates are the perfect combo for them. That is why gamers do not regret buying expensive gaming monitors. Unfortunately, the smartphone does not have a constant power supply like a screen to provide such a good experience.

Obviously Samsung knows very well this should be making a choice between the battery life and the smoothness of the screen. Will the 120Hz screen on OnePlus avoid this limit? We will know after it launches.
