Several iPod models have a minimalistic design with only a few buttons, so the steps to turn off your iPod may not be obvious. The iPod shuffle has a three-way slider that controls power and playback order, while the iPod nano and iPod touch models each have a Sleep button that controls the screen backlight and power. The iPod classic has a multi-function Play button that controls power or playback, depending on how long you press the button. When not in use, iPods automatically switch to a low-power state, and you can save power without ending your session by putting them in sleep mode.
Disconnect your iPod from any external power source, such as a computer or wall outlet. If connected to a power source, the iPod may simply be power cycled instead of turned off.
Finalize unsaved changes in any Web apps you may still have open. The iPod touch automatically saves locally installed apps' states when you pause or close them, but Web apps may contain information not yet uploaded to the server. You can view all currently open apps by holding down the Home button and then sliding the menu to the left or right. Web apps include word processors, image editors and other cloud services that run in a Web browser.
Power off the iPod. For the iPod shuffle, move the three-way slider so that the green power indicator is invisible. For the iPod nano and iPod touch models, hold down the Sleep button for a few seconds. The iPod nano immediately powers off, and the iPod touch displays a confirmation slider that you must drag across the screen. For the iPod classic, hold down the Play button until the device powers off.
