I noticed that when I am in my Corp Email that it was always syncing, the round symbol on the top right of the program just keeps on moving in a circular motion (aka Looping). I messed around with all possible sync options: Push Email Only Contacts Calendar Duration to Sync The only thing that caused this condition is my Corp Contacts. I have over 1,000 contacts. I think it was killing my battery, that is why I am concerned. Does anyone else have this problem?
