About this test
Refresh rate (measured in Hz) is how many times per second the screen redraws. 90, 120 or 144 Hz panels make scrolling and animations much smoother than traditional 60 Hz screens.
The measurement uses the browser's rendering rate, which follows the screen rate. Some phones switch rates automatically to save battery, so the value can vary.

Frequently asked questions
My phone is 120 Hz but the test shows 60 Hz. Why?
The high refresh rate mode is probably off in display settings, or battery saver is limiting the screen to 60 Hz.
Is the measurement 100% accurate?
It's a very close browser-based estimate. Small variations are normal; the peak value best represents the panel.
