Via Apple’s website, the company previously described the battery drainage issue as such: “When you respond to an exception to a recurring calendar event with a Microsoft Exchange account on a device running iOS 6.1, the device may begin to generate excessive communication with Microsoft Exchange Server. You may notice increased network activity or reduced battery life on the iOS device. This extra network activity will be shown in the logs on Exchange Server and it may lead to the server blocking the iOS device. This can occur with iOS 6.1 and Microsoft Exchange 2010 SP1 or later, or Microsoft Exchange Online (Office365),” remarked the tech giant.
Apple had provided users with a manual way to solve the problem but the company has emphasized the new launch of 6.1.2 corrects the issue.
Earlier this week, a report from the International Business Times shed light on the battery drainage problems, highlighting iPhone owner complaints via Apple Support Communities.
