Sync iPhone using iTunes on your computer
With iTunes on your computer, you can sync your music, movies, TV shows, photos, and more. After you sync, the content on your iPhone matches the content in your iTunes Library on your computer.
To keep your iPhone up to date, you can use iCloud or iTunes, or both, depending on your needs. For example, you can use iCloud to automatically keep your contacts, calendars, email, messages, and more up to date on all your devices, and use iTunes to sync music from your computer to iPhone. See Manage Apple ID and iCloud settings on iPhone for information on using iCloud to securely store your data and content.
Note: If you use iCloud for features such as music, photos, calendar, and contacts, you can’t use iTunes to sync their associated media and data.
Connect iPhone to your computer using USB
Make sure you have one of the following:
Mac with a USB port and OS X 10.9 or later
PC with a USB port and Windows 7 or later
Connect iPhone to your computer using the included Lightning to USB Cable. If your computer has a USB-C port, use a USB-C to Lightning Cable or USB-C to USB Adapter (sold separately).
Sync your iPhone content using iTunes
To sync, your computer must have the latest version of iTunes.
On your computer, open iTunes, then click the iPhone button.
Choose the content types you want to sync.
Click the Apply button in the lower-right corner of the screen to save your sync settings; if syncing doesn’t start automatically, click the Sync button.
After you turn on syncing, your content syncs each time you connect your iPhone to your computer and have iTunes open.
Unless iPhone is actively syncing with your computer, you can disconnect it at any time. Look at the top of the iTunes screen on your computer or on iPhone to see if syncing is in progress. If you disconnect iPhone while it’s syncing, some data may not get synced until the next time you connect iPhone to your computer.
