Accounts & sync settings
Use the Accounts & Sync settings to add, remove, and manage your Google Accounts 
and other accounts. You also use these settings to control how and whether 
applications send, receive, and sync data on their own schedules, and whether 
applications can synchronize user data automatically. 
Gmail, Calendar, and other applications may also have their own settings to control 
how they synchronize data; see the documentation for those applications for details.
Accounts & sync settings screen
Background data 
Check to permit applications to synchronize data in the 
background, whether or not you are actively working in them. Unchecking this setting 
can save battery power and lowers (but does not eliminate) data use.
Auto-sync 
Check to permit applications to synchronize data on their own 
schedule. If you uncheck this setting, you must touch an account in the list on this 
screen, press Menu
, and touch 
Sync now to synchronize data for that account. 
Synchronizing data automatically is disabled if 
Background data is unchecked. In 
that case, the 
Auto-sync checkbox is dimmed. 
Manage accounts 
The rest of this screen lists the Google Accounts and other 
accounts you’ve added to the phone. Adding accounts is described in “Accounts” on 
page 127.
If you touch an account in this screen, its account screen opens.
Account screen
This screen contains different options, depending on the kind of account.
For Google Accounts, it lists the kinds of data you can synchronize to the phone, with 
checkboxes so you can turn synchronizing on and off for each kind. You can also 
press Menu
 and touch 
Sync now to synchronize data. Touch the Remove 
account button to remove the account along with all its data (contacts, mail, 
settings, and so on). You can’t remove the first Google Account you added to your 
phone except by resetting your phone to the factory defaults and erasing all of your 
user data. See “Privacy settings” on page 370.
