Boasting an improved battery life, the fourth-generation Apple Watch combines advanced hardware and software into a singular, unified lightweight design. The display is over 30% larger and seamlessly integrates into the thinner, smaller case, while the new interface offers more information with richer, more vivid details. The speaker is louder than its predecessors, so users in noisy urban environment may still hear and respond to calls and notifications. Apple Watch Series 4 also brings revolutionary health monitoring and potential life-saving capabilities, including fall detection and the ability to take an electrocardiogram. Apple continues its streak of innovations that set the bar for wearable technology.
