Android’s #K-9 #Mail #battery life and Dovecot’s Push-IMAP | Peter Kieser

I am using K-9 Mail on my #Android phone, and would like to make use of the IMAP PUSH feature but I found it consumes far too much battery. In #Dovecot 1.2 when you initiate IMAP IDLE via your IMAP client (eg. K-9 Mail) Dovecot sends a message every 2 minutes stating “OK Still here”, this causes the mobile data connection to have to wake up and consumes excessive amounts of battery.
