Dynamic refresh rate
Android’s premium smartphones have had dynamic refresh rates for the last couple of years, especially since more manufacturers started adopting 120Hz right out of the gate. But that high refresh rate murders battery life in most situations, which is why Android OEMs started implementing dynamic refresh rates to help cut down on how much power the screen uses. The OnePlus 9 Pro was one of the first major Android flagships to adopt the ability to dial as far down as 1Hz to save on battery life. Some of Samsung’s latest smartphones, including the Galaxy S22 Ultra, offer this.
Apple introduced its version of the dynamic refresh rate, called ProMotion, in the iPhone 13 Pro and Pro Max, though it was limited to 24Hz. The iPhone 14 Pro can dial down to 1Hz for the always-on display.
