    Default Any imap email apps that use C2DM? Or, does K-9 Mail use C2DM?

    I'm wondering if my understanding of how K-9 Mail works is correct.

    I'm guessing that it doesn't actually use C2DM for push notifications, as that would require a K-9 server that would actually handle your email accounts. Instead, it seems that the app uses IMAP just like a computer program, such as Thunderbird, would. Anyway, if this understanding is correct, then wouldn't it be possible to save battery life if K-9 used C2DM?

    As an aside, is anybody aware of any email apps that do use C2DM? It would be great to have instant alerts for new emails but not take a hit in battery performance.

    It doesn't look like it does. By default, it queries Google Mail every minute, and burned a lot of power.

    I mostly use POP3, though, so it looks pretty good right now.

    Well, with K-9 Mail, I do receive messages instantly (through my Gmail account and through another IMAP account). I'm just wondering if theoretically, a mail app that uses C2DM could give better battery life with the same performance.

    Yes, according to this blog, it should save battery life.

    I'm kind of surprised that there isn't some other good e-mail service for Android, similar to BlackBerry's BIS. Gmail works fine naturally, but for all other IMAP accounts, it seems like the only option is a battery-draining app that keeps polling.
