===Dovecot Idle_Notify===
 +
Poor battery consumption issues has been reported with K9-mail on recent Android systems. It is apparent one way of helping this is to modify the imap_idle_notify setting. The default is in Dovecot, and therefore on SME is 2 minutes.
 +
 +
K9 has an idle refresh of 24 mins but it seems with Dovecot defaults at 2 mins it causes lots of wake ups and battery drain.
 +
 +
This is configurable via a config db property.
 +
 +
Default on install
 +
# config show dovecot
 +
  dovecot=service
 +
    Quotas=enabled
 +
    status=enabled
 +
 +
Set dovecot Idle_Notify to 20 minutes
 +
 +
# config setprop dovecot Idle_Notify 20
 +
# config show dovecot
 +
  dovecot=service
 +
    Idle_Notify=20
 +
    Quotas=enabled
 +
    status=enabled
 +
 +
Expand template to update *.conf (can also issue a full reconfigure/reboot)
 +
 +
# expand-template /etc/dovecot/dovecot.conf
 +
# dovecot -a |grep imap_idle_notify_interval
 +
  imap_idle_notify_interval = 20 mins
