iOS 6.1.2 Is Already on the Way with Bug Fixes

Mal installed iOS 6.1.1 this week and already we soon see another update coming in our devices. This is because Apple has not got a serious bug for corporate users, referring to Microsoft Exchange. She has assumed the flaw in a support document and says that you will notice in a future system update.
The bug happens when there are recurring events in the calendar of Exchange, causing the connection to the server is repetitive, so spending more battery. To solve the problem while Apple does not release the update, simply turn off the calendars account for 10 seconds and then reconnect them.

Symptoms: 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).

Resolution: Apple has identified a fix and will make it available in an upcoming software update. In the meantime, you can avoid this bug by not responding to an exception to a recurring event on your iOS device. If you do experience the symptoms described above, disable then reenable the Exchange calendar on your iOS device using the steps below.

1. Go to Settings > Mail, Contacts, Calendars
2. Select the Exchange account from your Accounts list.
3. Turn the switch for Calendars to OFF.
4. Wait ten seconds.
5. Turn the switch for Calendars back to ON.
