Apple Explains Problems with iPhone Battery Life Since the Release of iOS 6.1

by Reads (6,460)

Apple has tracked down why some users have seen a dramatic drop in the battery life of their iPhone since the release of iOS 6.1: there’s a problem with those who use Exchange for their calendar.

Apple’s description of the problem:

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.

Apple has promised to fix this issue in an upcoming version of the iOS, but did not say when this will be introduced.

In the mean time, the company suggests that users not respond to exceptions in recurring events on their Exchange calendar on their iOS device. Anyone who believes their smartphone or tablet is already affected should:

  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.

While many business users get their work email, calendar, and contacts from an Exchange server, they aren’t the only ones. Google allows users to get their Gmail, Google Calendar, and Contacts through Exchange as well.
