There is no ON / OFF button for the Apple Pencil. The Apple Pencil only takes 15 seconds of charging through the Lightning connector for 30 minutes of use. This means you can pick up your Pencil at anytime, quickly charge it and begin using it in literally seconds. You can also use the Apple Pencil as a basic stylus without the touch-sensitive features on supported apps when it is not charged.
How do I turn off or put the Apple Pencil to sleep?
