If you’ve got bugs in your products you’d assume the company who made them is going to fix them, but it’s reassuring that Apple’s come out and said it specifically. Apparently Cupertino’s identified the bug that’s killing iOS 6.1 iPhone batteries, and is in the process of crushing the life out of it. Meanwhile, here’s what you have to do to stop it for now.
Apple’s support note basically describes the same steps as Microsoft did, trying to help out its Exchange server users. The bug is caused when “you respond to an exception to a recurring calendar event with a Microsoft Exchange account on a device running iOS 6.1.” It causes the device to “generate excessive communication with Microsoft Exchange Server” draining your battery and causing issues for the server while it’s at it.
Apple suggests the following until it manages to push out an update:
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.
Let’s hope Apple gets things fixed up and pushes out an update for the insane battery drain sooner rather than later. Oh, and it better not patch up the Evasi0n jailbreak hole while it’s at it. Then I really would be pissed. [Apple]
Thanks Jeff!

i don’t have any exchange accounts on my iphone5, only have icloud and google and my battery wont last half a day since update to ios6.1.
Mines fine. Absolutely no problem after the latest update.
It did appear to have a problem beforehand, but it wasn’t terminal all the same…
Phone’s on o2…
The misses has an 4s and the battery life is shocking – since her last update a couple of days ago.
I have the 5 and I did use exchange for the first week of having the phone but have ditched it, whats the point in taking work emails home and out of the office when your not getting paid for it and to be quite honest – exchange on the iphone 5 is crap and doesn’t accept the password all the time, causes my account on the work domain to become locked out and there is issues when responding to meetings etc.
Apple should get exchange sorted properly – on Android and Windows Phone it worked perfect, all I had to do was input the email address and password and off it went and configured everything – even rules & folders etc all worked, in the iphone – it’s not that simple, you have to manually select what folders you want to push… total shite
