Apple will do nothing, ATT or whoever your carrier will do nothign when you get dinged with overage charges from the bug in Apple's IOS 6.1. You need to shut off all your icloud uses and delete all your email accounts. power down your iphone. reboot and reload your email accounts. It will work. It worked for me.
Update on this thread: It seems that if you have the Exchange account turned on in "Notifications" also causes the phone battery to drain pretty fast and heats up the phone even after you delete and readd the Exchange account. Definitely is a problem with Exchange connection and with the 3G network as well.
Apple must correct this problem ASAP.
I have the same problem with iPhone 5 and iPad 2. After installing IOS 6.1 the battery life has dropped dramatically.
Before the update my iPhone 5 had about 50% to 80% battery left at evening. With IOS 6.1 it goes to 20% or even dies before evening.
With iPad 2 which is used much less I had before 6.1 always almoust full battery. Mu iPad2 went to charge with 70-80% battery capacity. Now it often has 25% left at the same situation. Before I always could just grab the iPad along with me, but now it is useless as it has not much batterylife left.
Please deliver the bug fix Apple.
And you lucky ones that have not yet updated to IOS 6.1. Don't do it.
Nope, what I meaned was that I was running out of battery after 5-6 hours oy my own usage (including standby periods with 3G - not in Airplane mode, email reading etc...).
After disabling the "Calendar" sync for my 2 echange accounts, I'm now back to over 17Hours (again including standby period, but also email checking and a couple of othre things).
I tried yersterday evening to set the Calendar sync back On for my two exchange accounts, and just letting the phone with 3g/Wifi, not touching the phone at all (so screen off, no gaming etc...) the phone lost about 50% of battery in 3hours....
So clearly something wrong with the Echange Calendar sync. I'm seeing this on 3 different Iphone 4S, with the same "fix" working for all of them so far.
AOL has informed its corporate employees that it has temporarily disabled the ability to manage meetings via mobile devices due to a bug with Apple’s iPhone, iPad, and iPod touch iOS 6.1 operating system. We received an internal email from a source detailing the announcement from AOL CIO Michael Freker.
Below is a statement from Freker to 9to5Mac that details the situation:
“AOL’s corporate Enterprise Messaging Operations team has been monitoring a rapidly increasing and unusually large volume of traffic across our enterprise mail environment originating from iOS devices running the new iOS 6.1 update. We have researched this problem and appears to be connected to a recently identified issue that seems to cause these iOS devices to continuously loop while synchronizing a recurring calendar meeting invitation. Similar problems have been reported by a number of sources to several media outlets across the Web in the past few days. While our team continues to work productively and rapidly with Apple and Microsoft to resolve the issue, it has been necessary to temporarily disable the ability to accept or manage calendar meetings using mobile devices to ensure that we maintain the integrity of our corporate enterprise messaging platform. Since this change is limited to managing calendar invitations, by disabling them temporarily we allow our employees to continue to experience the excellent productivity these devices bring to our enterprise until this issue is resolved.
The iOS 6.1 bug causes a “continuous loop” when meetings are attempted to be managed. This leads to a degraded iOS device performance and battery life experience. AOL is working with Microsoft and Apple to resolve the issue.
Issues with iOS 6.1′s Exchange support has also been highlighted on Microsoft’s forums. “I had a user upgrade to 6.1 and immediately after he finished, his [iPhone/iPad] started causing excessive logging on the exchange server,” one of the postings reads. ZDNet also notes the issue with iOS 6.1 and Exchange servers.
My (Unnamed Fortune 500 company) has also "banned" 6.1 from using Calendars.
This is getting big.
Usage time is very vague, and really depends of what is the usage you are talking about (phone, email, game with / without 3g etc...)
That's why I mention 15-17H for my own daily average usage, which is more or less on a week day:
- 2 to 3 hours on the phone
- couple of hours reading/writing email
- remote my media center
- 30mn-1h on imdb
- 1 hour random browsing with safari
- 1hours spent in the tube - (=low 3G signal resulting in higher battery consumption if using it)
- 1h running some random apps not requiring network (so only real battery consumption is cpu and screen)
- 20-30mn checking calendar meetings details (but not at the moment, due tothis damned 6.1/Exchange issue)
with this type of usage, I'm unplugging my IPhone at 9.30AM, and run out of battery around midnight/1AM.
But as you can see, "usage time" from a user t another can really differ... so the battery consumption during this usage period.
I'm not using GPS/Maps too much who can hit the battery really easily (3G+GPS used in the same time). And when I do so, I'm getting far from the 17Hours without the need of finding an AC plug...
My i5 16GB used to run full day or two on a charge. Now I'm luck if it can survive a couple hours. I also noticed it's fairly warm most of the time. I turned of push notification for Exchange (turned to manual), and have tried using LTE or just 3G. Doesn't matter, the battery still gets drained right quick. Apple better come up a with an update soon. This *****. Battery life was one of the main selling points when I switched from an Android phone.
Disabling push notifications is not relevant in the majority of cases, and neither is what kind of cellular connection. It is overwhelmingly due to a bug in the interaction between iOS 6.1 (and, unfortunately, iOS 6.1.1; iOS 6.1.1 does not fix the issue, and a friend of mine who hit the problem with the upgrade from 6.0 -> 6.1 hit the same issue *again* upon upgrading from 6.1 -> 6.1.1!) and Exchange. It is in almost every case (every case I have had any direct experience with) an iOS / Exchange Calendaring problem, and it can be solved entirely by means of:
(1) deleting your Exchange account fully from your iPhone (Settings->Mail, Contacts, Calendars->your exchange account->Delete Account -- don't forget to note your settings so you know how to set it back up!), then
(2) rebooting your phone, then
(3) re-adding your Exchange account.
You don't have to nuke and pave the whole phone. You don't have to change your settings to disable anything such that you have to live without it forever after. It just gets stuck in a loop during the upgrade, and the method above unsticks it. It's not ok. They need to fix this... but they can't possibly fix it soon enough to be satisfactory, so this work-around is at least minimally painful!
I am really encouraged by Spinct0r's post, above, about AOL and other companies considering this a serious issue, because it means this is gaining some serious visibility, so Apple will have to take notice and fix it.
P.S. Saym -- While possibly illuminating, I don't think that's what coolkenny13 meant. I believe he meant you to go to Settings->General->Usage, scroll to the bottom and tell him what it says under "Time since last full charge" title for "Usage". When I was hit by the bug, my Standby and Usage times were identical ... which means, if you see it, that something is preventing your iPhone from ever going into standby mode. The bug relating to Exchange Calendaring does just this; prevents your phone from going into standby because it always has work to do.
I'm beginning to think this is not a Exchange problem. I deleted my Exchange account. I full restored my iPhone. I deleted the iCloud account. Although it seems better now, while using Wi-fi, the problem remains while using 3G. Once the phone gets a 3G signal, it starts to heat up a lot (while using it for browsing or email) and the battery is draining 1% per 2 minutes. I did not re-add my Exchange account. I was really happy with my new iPhone 5 because I was only charging it every 2 days or so. Apple released the iPhone 4S 3G fix, but I really hope that they release a fix for the iPhone 5 as well.
