After the upgrade to K-9 Mail 5.010, it seems that the software is draining the battery of my Samsung S5 (Cyanogenmod Marshmallow) way more than before (old K-9 version unknown). In fact, K-9 mail is by a factor of >4 largest consumer of battery power (next being Android OS).
I have four accounts configured, 3x IMAP, 1x POP3 (hourly).
