“Push” means never having to check for updates, but it also means faster
battery drain. At SettingsÆFetch New Data, you can turn the “push”
feature off to save battery life when you’re desperate. Now your iPhone
checks for updates only on a schedule—every 15 minutes, every hour, or
whatever you specify in the Fetch section here. (Except for Web bookmarks.
They’re always “pushed,” no matter what your setting here.)
Or, perhaps wisest of all, you can choose Manually. Now the iPhone
updates the data in each program—Mail, Calendar, or Contacts—only
when you open that program.
You can also specify “push” or “fetch” (on a schedule) settings for each type of data
individually. You can make the calendar “push,” but the email “fetch,” and so on. To
find these controls, tap SettingÆFetch New DataÆAdvanced.
