Running latest version of Gingervillain. Have 2 accounts setup in Android default Mail application. One is set to refresh "never" and the other is an Exchange account setup for "Push". Most days, I never see the Mail app on my battery usage screen - and I'm connected to Wifi most of the time at work and home. Lately though, Wifi at work has been down. I'm noticing that when this happens, battery life is significantly decreased, and the Mail app shows on the battery usage screen. Out of 12 hours today, Mail app was showing as partial wake time of 4+ hours. Any idea what could be causing this problem? I was under the impression that using Push with an Exchange account should use very little battery. Additional note: When I'm not on Wifi, my mobile data only comes on for a couple minutes every half hour (a profile in Tasker) so it's not like I have mobile data on all day.
