I guess I'm stuck waiting 15 minutes for new mail notifications, and running my battery down. I'm not forwarding my mail anywhere or running Exchange (or a clone). The latter, in particular, is a power-hungry option ...

I'm using the K9 client on my Sprint EVO. AFAIK, K9 is the only android
|
|
client that supports IDLE. I have 3 accounts on my phone. All have a
|
|
constant IDLE connection. I get easily 12-14 hours of battery life. I
|
|
plug it in when I get home, so that's plenty.
|
|
|
|
(off topic) Using the GPS is what kills my battery. With constant GPS
|
|
usage, I can kill a battery in 3 hours.
