Some iPhone users have found a reduction in the autonomy of their phones and abnormal overheating them after upgrading to iOS 6.1. The problem seems to be related to a bug in Mail with Exchange accounts leading to a loop device to sync with Microsoft service servers that explains these two symptoms linked to an unusually high data traffic.
In U.S. AOL Company has instructed its employees to temporarily disable calendar sync for meeting management on their phones with iOS 6.1 at the time who have contacted Microsoft and Apple to try to resolve the problem.
While waiting for the 6.1.1 update, a temporary solution to the problem is to establish a rule on the Exchange server described DevCentral to reject the connection, though perhaps “patch” is the word that best describes it.
