The lightning-fast responsiveness of Apple Pencil separates it from other creative tools. That’s because its latency — the tiny delay between when you begin drawing and the time it appears on the screen — has been reduced to an almost imperceptible level.
Within its slender case are intricate and accurate pressure sensors, capable of measuring a range of forces. The carefully positioned sensor determines precisely how hard the tip of Apple Pencil is being pressed down.
Two tilt sensors built within the tip of Apple Pencil calculate the exact orientation and angle of your hand. As you naturally write or draw, the relative positions of each of these sensors can be detected by the Multi-Touch display.
15 seconds of charging = 30 minutes of battery life.
