Maximizing Battery Life
iPod touch uses lithium-ion batteries. To learn more about how to maximize the
lifespan and battery life of your iPod touch, go to www.apple.com/batteries.
Replacing the Battery
Rechargeable batteries have a limited number of charge cycles and may
eventually need to be replaced. The iPod touch battery isn’t user replaceable; it can
only be replaced by an authorized service provider. For more information, go to
www.apple.com/support/ipod/service/battery.
Security Features
Security features help protect the information on iPod touch from being accessed
by others.
You can set up a passcode that you must enter each time you turn on or wake up
iPod touch.
Set a passcode: Choose General > Passcode Lock and enter a 4-digit passcode,
then enter the passcode again to verify it. iPod touch then requires you to enter
the passcode to unlock it or to display the passcode lock settings.
For addition information about using a passcode lock, see “Passcode Lock” on
page 114.
