iOS 6.1 – Indiana Jones Apple And the Sync Of Doom!
If you’ve updated your iPhone to iOS 6.1 and you’ve found your device constantly drained of battery life, or your data plan has maxed out really quickly for no apparent reason, or your network carrier has begged you not to upgrade to iOS 6.1 because it’s brought their network down (yes, that has happened), well, Apple finally has an answer: it’s the Sync of Doom!
Yes, from Apple, the same company that brought you Antennagate, now we have the Sync of Doom! (I love saying that!) What happens when you have an Apple iOS calendar app syncing to a Microsoft Exchange server for calendar information? Well, usually nothing unexpected.
But!
… If you do that and happen to change a single instance of a reoccurring event, an Apple bug will cause the iOS app to infinitely attempt to sync with the Microsoft Exchange Server.
Flooding all servers in between your iPhone and the Exchange Server with useless sync attempts, often dragging those servers to a crawl.
Not to mention causing your iPhone to chew up your 3G or 4G data plan like it was nothing.
Or for that matter eating up the battery of your iPhone by keeping the phone constantly communicating wirelessly and never able to go to sleep internally.
As the Sync of Doom! from Apple’s buggy iOS calendar app continues trying over and over and over to sync to the Exchange server.
Basically, this is really a bug that should have been caught long before release.
But wasn’t.
The Sync of Doom!
Brought to you by Apple.
There is some good news however. If your phone is suffering from the Sync of Doom! you can manually make it stop. Disabling and then re-enabling the connection to the Microsoft Exchange server seems to fix the Sync of Doom! (Which is basically to turn your calendar off, and then back on.)
Of course when the Sync of Doom! bug will actually be fixed is another matter entirely. It hasn’t happened yet, that’s for sure. When Apple will get around to releasing that fix, you’ll just have to wait to find out.
So if you’re an iPhone user and your calendar data comes from a Microsoft Exchange Server, you’re going to want to be extra careful. Consider this your warning. There’s a bug, but with diligence you can prevent it from eating up your data plan, eating up your battery life, and bringing networks to a crawl. It’s not a virus. It’s just Apple being Apple lately.
