I use K-9 email on a Motorola Milestone (Android 2.0). Is there a way to set the ping time to keep the imap idle connection alive for push email? If there isn't, what is the standard setting? My imap server allows ping every 60 minutes for imap idle; I'd like to set it this way as I understand it should improve battery life. At least that's what I experienced with Profimail (which lets you customize this setting) on my Nokia. Thanks! PS Any idea how much battery imap idle drains vs polling the mail server every, say, 5 or 10 minutes?
