You know what sucks? Having to turn your phone’s screen on just to check whether you have notifications or to check the time. With the new Apple iPhone 14 Pro and iOS 16, Apple introduces its ‘always on’ display.

By dropping the refresh rate of the screen to once per second, and a super-low-power mode, it means the screen can show you the most important info at your fingertips at all times without dramatically losing your battery life.
