|A bug in iOS 6.1 that played havoc with battery life and resources on the iOS device and caused excess logging and usage on Microsoft Exchange-based servers when syncing with iOS devices has been identified, Apple reported on Wednesday. The company says a fix will be made available in a forthcoming update, but doesn't give a firm timeframe. Under iOS 6.1, devices that try to sync with a site running Microsoft Exchange Server 2010 cause errors and problems on both the device and the server.
The problem was severe enough that AOL and other companies asked users of iOS 6.1 to refrain from connecting with work servers until a fix was found. Microsoft initially recommended that Exchange administrators ban users of iOS 6.1 from accessing Exchange services or at least throttling their use. It also offered a workaround option for administrators yesterday.
Apple says it identified a fix, reports ZDNet, and in such situations generally releases a patch within a day or two of an announcement like this. Both MS Exchange Server 2010 and Microsoft Office 365's Online Exchange were affected by the problem, which caused excessive logging leading to increased use of CPU and RAM resources.
