I too am a pro user and have had high battery usage, so much so I uninstalled Aquamail. Periodically I reinstall it and,see if it is any better on battery because it is without a doubt the most functional email app available. I am hoping the recomendations in this thread help. I have it installed currently an set to sync 25, cache 50, and have all push and scheduled sync disabled on 2 imap and 1 gmail account. Fingers crossed!
