how does help me "save battery" if i have a folder-structure maintained by sieve if i do not get my new mails? If you open 10 connections to IMAP server and will IDLE on them - your phone will wake up to reply for ping in every of that 10 connections. Imagine if there will 100 folders? Like mentioned previously in this thread, you can disable the "ping"s in Dovecot. And even when they happen Dovecot makes them happen at the same time. So I think the power usage difference between 1 connection and 100 connections isn't much.
I guess, there is no trick, that will change the linear complexity by traffic and by CPU usage. If you can change settings in dovecot - you can set up ActiveSync there. It's more suitable for mobile mailing.
