As a general rule, turn off your iPad whenever you know you won't be using it for a while. If you plan on using your iPad soon, then put it in sleep mode.

Airplane mode is most useful when you're stuck in an airplane and don't feel like interacting with any of your fellow passengers, preferring to let your iPad amuse you instead. It's also a good way to save your battery life.

Now that you understand the basics of turning your iPad on and off (and everything in between), the rest of this book will teach you how to use all the other features of your iPad so you can do something useful with it.
