Check your phone step by step
- Open this page in Chrome, or your usual browser, and don’t scroll for two seconds while it measures.
- The big number is the rate the browser draws at, and the verdict under it compares it with 120 Hz.
- If your phone is rated for 90 Hz or 144 Hz, pick that in the Rated refresh rate list and the verdict updates at once.
- Below lists the settings to check. Change one, come back and press Measure again.
Turn on the high refresh rate
Samsung Galaxy. In Settings, search for Motion smoothness. Samsung describes Adaptive as adjusting the refresh rate dynamically up to 120 Hz, and Standard as a fixed 60 Hz with the best battery life. Power saving mode switches the screen to Standard, so a Galaxy in power saving reads 60 Hz here.
Google Pixel. Open Settings, Display & touch, and turn on Smooth Display. Google says Smooth Display raises the refresh rate for some content, up to 90 Hz on the Pixel 7 and 7a and up to 120 Hz on the Pixel 7 Pro, 8, 8 Pro, 8a and Fold, and that Battery Saver turns it off. Newer models list Smooth Display in their Google Store specs, for example 60 to 120 Hz on the Pixel 9a and Pixel 10 and 1 to 120 Hz on the Pixel 10 Pro.
Other phones. Look in the display settings for a refresh rate or smoothness option, and check the phone’s specifications for its top rate: a 90 Hz phone passes at 90 Hz, not 120.
Why the reading can still be lower
Android chooses the refresh rate itself. According to the Android Open Source Project, the system picks a rate that suits what apps are drawing (apps can also ask for specific frame rates), switches to the phone’s default rate for a short time when you touch the screen, ready for animations, and caps the maximum at 60 Hz or less in battery saver. So a phone set to Adaptive can read differently from one measurement to the next: turn battery saver off, don’t scroll while it measures, and press Measure again to compare.
To see what the phone itself reports, turn on Show refresh rate in Settings, System, Developer options. The overlay shows the rate the display is using, which you can compare with this page’s reading. In the motion test, the top row at 120 Hz moves in steps half as long as the 60 fps row.
For iPhone and iPad, use the iPhone 120 Hz test. Computer monitors have the 144 Hz test and 240 Hz test, and the plain refresh rate test works on any screen.
