Preventing iPhone from syncing automatically

By default, contacts, calendars, and other information is automatically synced when you connect your iPhone to your computer. You can prevent a specific iPhone from syncing automatically by connecting the iPhone, selecting it in iTunes, and deselecting “Automatically sync when this iPhone is connected” in the Summary pane.

You can also prevent automatic syncing of all iPhones.

To prevent automatic iPhone syncing:

  1. In iTunes, choose Edit > Preferences.

  2. Click iPhone.

  3. Deselect “Disable automatic syncing for all iPhones.”

If this checkbox is selected, the iPhone won’t sync automatically, even if “Automatically sync” is selected in the Summary pane. To sync your iPhone and your computer, connect the iPhone and choose File > Sync iPhone. You can sync iPhone with only one iTunes library at a time.

For more information, see the iPhone user’s guide or the Apple support website.
