While lots of people these days use their iPhones without ever syncing with their computers, many still use iTunes to transfer files back and forth. You can sync songs, playlists, albums, movies, TV shows, audiobooks, books, and podcasts between your computer and iPhone using iTunes.

Syncing isn't just for transferring data, either. It's also a good way to back up your iPhone. Although Apple encourages users to use iCloud to back up their personal data, you may also want to back up your iPhone by syncing it to your computer. 

NOTE: While iTunes used support syncing apps and ringtones, those features have been removed in recent versions and are now completely handled on the iPhone.

The Summary Screen

Sync iPhone to computer, step 1

The first step to syncing your iPhone to your computer is simple: Plug the cable that came with the iPhone into a USB port on your computer and into the Lightning on the bottom of the iPhone. (You can also sync over Wi-Fi, if you prefer.)

Launch iTunes. Click on the iPhone icon in the upper-left corner of the window to open the Summary screen. This screen offers a basic overview and option information about your iPhone. The information is presented in three sections: iPhone, Backups, and Options.

iPhone Section

The first section of the Summary screen lists your iPhone's total storage capacity, phone number, serial number, and the version of the iOS the phone is running. The first Summary section contains two buttons:

  • Check for Update lets you make sure you have the latest version of the iOS. If not, you can update it here.
  • Restore iPhone lets you return your iPhone to factory settings. This erases all your personal data from the iPhone and is recommended before you sell or give away your phone. Restoring the iPhone is also an advanced troubleshooting option for solving problems with your phone.

Backups Section

This section controls your backup preferences and lets you make and use backups.

In the area titled Automatically Back Up, choose where your iPhone will back up its contents: iCloud or your computer. You can back up to both, but not at the same time.

  • iCloud: Check this box to use iCloud to back up your most important data.
  • This computer: Check this box to make a full backup of your data on your computer.
  • Encrypt iPhone backup: This password protects the backups on your computer. This is optional but recommended if you share your computer.

This section contains two buttons: Back Up Now and Restore Backup:

  • Back Up Now: This backs up your iPhone to your chosen location immediately.
  • Restore Backup: Use this to replace what's on your iPhone with a saved backup.

Options Section

The options section contains a list of available possibilities. The first three are important to most users. The others are used less frequently.

  • Automatically sync when this iPhone is connected: Ensures that iTunes launches and syncs the phone whenever you connect it to the computer. Consider unchecking this if you connect your iPhone to multiple computers.
  • Sync with this iPhone over Wi-Fi: When this is enabled and your iPhone is on the same Wi-Fi network as your computer, it syncs automatically—no more cables!
  • Sync only checked songs and videos: Useful if your iTunes library is bigger than your iPhone's capacity.
  • Prefer standard definition videos: Designed to conserve storage space. This option ensures that, if you have both HD and standard definition versions of a video, the smaller, standard definition version is synced.
  • Convert higher bit rate songs to 128 kbps AAC: Converts songs to the AAC format during syncing. This helps conserve space if your songs are encoded in other formats or at higher bit rates, which results in larger files.
  • Manually manage music and videos: Disables automated syncing. Instead, allows you to manually add and remove all content on your iPhone. Not recommended unless you have a specific reason.
  • Reset Warnings: If you have previously dismissed any alerts or warnings on your iPhone, you can see them again by clicking this button.
  • Configure Accessibility: Turns on accessibility options for people with hearing or visual impairments.

At the bottom of the Summary screen is a bar that displays your phone's capacity and how much space each type of data takes up on your iPhone. Hover on a section of the bar to see additional information about each category.

If you make changes to the Summary screen, click Apply at the bottom of the screen. Click Sync to update your iPhone based on the new settings.
