Tip - Optimize your data-fetching intervals

Optimize your data-fetching intervals

In layman's terms: For apps that don't rely on info being pushed to them, updated data is fetched at specific intervals — like your phone checking for new email messages every few minutes. Fetching data more often will drain the battery more quickly. So for things like mail, make sure your phone is not fetching too frequently. On an iPhone, you can find it under Settings, Mail, Contacts, Calendars, Fetch New Data and choose "manually" or "hourly" depending upon your needs. For services that rely on push (like many mail accounts), follow the same path but set Push to "Off" so new data comes in based on your fetch setting. And if you have email accounts on your phone that you don't use anymore, turn them off or delete them altogether.
