Gone are the days when the default refresh rate for smartphone displays was 60Hz. Now most phones have either a 90Hz or 120 Hz refresh rate. Asus ROG 3 goes beyond the bar with a 144Hz refresh rate.
A refresh rate is basically the number of times a screen refreshes a new image in a second. Or just how often a display updates it’s content.
It is measured in Hertz (Hz).
The higher the refresh rate the smoother the user experience. High refresh rate displays are common nowadays including in budget phones.
Since a high refresh rate demands more battery,most phones switch between various refresh rates depending on the task the smartphone is performing.
For example most smartphones will switch to 60Hz when you’re watching a video or taking a photo or a video.
When you’re gaming or scrolling through your phone the display will remain at the highest refresh rate.
Other phones like Samsung S21 Ultra uses an LTPO display.
LTPO stands for low-temperature polycrystalline oxide and it refers to a particular type of backplane technology seen in OLED displays.
LTPO displays can switch refresh rates upto 1HZ when the phone is idle which is a good way to conserve battery.
All that said here’s how to keep track of your phone’s refresh rate every second.
Go to your phone settings and search “developer options.”
Scroll down until you get to “show refresh rate” and turn it on.
And you’re done. Your refresh rate will display at the top left corner of your screen.
