Exchange Active Sync Draining iPhone Battery Quickly. Help?
Exchange Active Sync seems to drain battery on both Iphone 4 iOS4 and iOS5 software platforms. I have 3 users that this is happening to. Users are on both AT&T and Verizon networks. Exchange is 2003 and the version is 6.5.7638.1. I’ve tried rebooting the phones (soft and hard resets), redoing push (Deleting the account and re-adding it), and restoring as a new iPhone (as a new iPhone not from backup) with no success. When you are in the mail account you just see the account trying to sync constantly, the battery drops like a rock, and the battery gets hotter than usual. This only seems to happen to users after they go away for a weekend trip or leave the geographical area where they live. I’ve even updated roaming capabilities on the phones. These are not the only users I have. Myself for example, I have exchange set to push, I’m on the Verizon network, and I have no problems. Does anyone know how to fix this issue?
iPhone 4, iOS 5
