The iPhone 15 action button is one of the most highly anticipated rumored new features for the next-generation phone line. It's reportedly replacing the mute switch. I don't think anyone will be playing Taps for the forgettable slider, so we're elated that Apple is reportedly swapping it out with something more serviceable.
However, what, exactly, is an action button anyway? Well, it's expected to work similarly to the action button featured on the Apple Watch Ultra, which can launch the stopwatch, initiate workouts, turn on the flashlight, double as a shortcut for the Dive feature and other functions.
