* What's the phone screen refresh rate?
Displays aren't static. Content and motion appear smooth on your phone's screen because every pixel updates to display the latest content from your handset's processor. But this doesn't happen randomly. Panels update their content at regular intervals, known as the refresh rate.
The refresh rate measures how quickly the phone's display updates. In other words, how often and quickly the content on the screen refreshes. Measured in Hertz (Hz), the refresh rate counts the number of times the display refreshes every second it is on. A 60Hz display refreshes 60 times per second, 90Hz is 90 times per second, and 120Hz is 120 times per second. So a 120Hz display refreshes twice as fast as a 60Hz panel, and 4x faster than an old 30Hz TV.
* What's the high refresh rate phones?
High-end smartphones increasingly boast blazing-fast 90Hz, 120Hz, and even faster refresh rate displays.
The benefits of high refresh rate phones and even how they work is rarely well understood. While games, movies and content can look a lot smoother, whether it's worth the extra battery consumption depends a lot on the user and the handset.
* What's the Refresh Rate Checker App?
Refresh Rate Checker is a free App to identify the phone's screen refresh rate and make multiple framerates motion test.(e.g. TestUFO animations)
