iOS 6.1.1 Didn't fix the Battery drain (4S)

Yes, you are correct. The problem occurs under specific circumstances:

• Exchange 2010, Fixpack 1 and higher
• What triggers it is accepting an invitation for a changed single instance of a repeat event on the phone
• Both Microsoft and Apple have recommended a workaround until they release a fix:
• First, don't accept invitations on your phone.
• If you do accept one and the battery starts draining, go to Settings/Mail,Contacts,Calendars, tap on the Exchange account name and turn off Calendar Sync
• Wait 10 seconds, then turn it back on.
• This will delete all events, then put them back. My experience - If you have a lot of appointments or a long history (I have 14 years) wait longer than 10 seconds. Check the calendar and wait for it to be empty.

While it has been reported for 6.1.1, I had this same problem a couple of years ago, and the same procedure fixed it. Except that I didn't know it was the calendar, so I turned off everything for the account. I suspect it is an old bug that was fixed, then was reintroduced in a recent release.

same for me. never had any issues with the battery, but since the 6.1.1 update yesterday a full charge only lasts 4h - without touching the phone at all. (gps, bluetooth off). This is really frustrating. Plus, you can feel that the device gets really hot - so, something is running.

I guess it's apples way of telling us to buy a new iphone... lol

I can confirm, that 6.1.1 didn't fix the battery drain problem. Prior to IOS 6.1 my battery would last almost 2 days with light usage. Today with IOS 6.1.1, my battery went from 100% down to 26% in 6 hours. I only sent 2 text messages.

fixed it for me. Initially deactivated the exchange account, which already worked. Tonight I'll go through the entire procedure of deleting and setting it up again, but at least I know what works on my iPhone...

Interestingly enough I did not have this issue with 6.1. Only 6.1.1

Guys try a restore or ever a DFU restore especially if you updated OTA. I have 6.1.1 and battery is fine. So the iOS isnt necessarily the problem. That link about exchange is a common issue. In the past it was mail in ActiveSync creating the same problem. Constant running and heating up battery. Symptom other than heat is standby and usage is the same. Anyway try the restore or DFU restore and see how it goes. iOS 6.1.1 can work. I have 2 exchange accts (gmail) with mail and calendar sync and all is fine. Not to say that it may not get hung up but so far so good even with exchange.

The article is a little misleading, because it implies that this is uniquely a 6.1 problem. However, a scan of the forums will show that this particular issue with Exchange goes back 5 years to the first version that supported Exchange, and the fix was the same then as it is now - turn off or delete the account, reboot, and add it back. This isn't as big a deal as it sounds, because the Exchange server will resync pretty quickly over WiFi.

The note that there were 20,000 views is also misleading; there was a similar thread for iOS 5 that had 1.5 MILLION views. 20,000 views is not many for forums as busy as these.

Here's what I did that seems to have fixed my battery draining problem.

I had a recurring calendar event with no end date in my Exchange calendar hosted at my work. I removed it AND restarted my device a couple of hours ago. I touched nothing else. Now my battery is still sitting at the same level and my device is cool to the touch.

Hopefully this helps someone else.

The article refers to the first calendar problem that occurred back in October 2012 with iOS 6.0 when Microsoft told operators of Exchange systems to not have their iPhone users upgrade to 6 due to issues with calendar invitations. There have been problems between Exchange and mobile phones since thery first had Exchange compatibility. Problems previous to iOS 6 usually involved a password that got out of sync or sometimes calendar invitations not being received.

The invitation loop first appeared with iOS 6. The recent update to iOS 6.1 has accelerated the loop and is causing the phone to constantly ping the iPhone. If you have enough iPhone users it will cause a drain on the Exchange servers, hence the warning by Microsoft.

Any agency I still do work for began having power drainage issues with 6.0, it was not relieved by 6.0.1 or 6.0.2 and has been made worse with 6.1. Previous fixes that I've used and you mentioned, removing the account and replacing it, does not work with this particular issue. I worked with their IT guy and we went through several options. The only one that stops the battery drainage/loop was to not use the Exchange calendar (fortunately there has been no appreciable drain on the Exchange server as only 5 people are using recent iPhones updated to 6; most of the younger employees have switched to Android, which have a different problem). The other option is to live with the battery drain or get a battery case, which still won't last a whole day. There is a third option that stops the battery drainage and allows use of the calendar but it cannot be discussed here.

The article is not misleading and is one of many out there describing the problem in the same terms. iPhone users will either have to avoid updating to 6 if they have not already done so, live without their Exchange calendar, live with the battery drain, use a different phone for awhile, use unapproved means and/or wait for a fix from Apple/Microsoft.

I did the 6.1.1 update and it did not fix my battery drain. I do not have an Exchange account. My ipone 4s was fine prior to updating to 6.1 and 6.1.1. Now my phone is useless. Today it died at 6 1/2 hours with very light use.

My o2uk iPhone 4S is now very hot after overnight charging on 6.1.1

Never experienced this on any firmware since iOS 5 when the device was new, I need to go back to iOS 6.1 ASAP as it was fine for me

Why can't you just do it right?

Well, I have 2 Exchange accounts, I have upgraded to 6.1.1, and I do not have any battery drain issues or problems with either Exchange account. So there is some other factor involved. I DID have a problem with the Exchange account of iOS 4.

It would be the best if we can downgrade back to 5.1.1!

On this release of iOS there was no problem, everything worked fine.

We are the customers, we pay for the service, not the apple.

Anyway I have realized that during call, when I changing the volume, the volume indicator is very choppy.

Another issue is with the automatic brightness, that is choppy too. .

I have three iPhone 4S phones, two on 6.1 and one on 6.1.1, all with terrible battery issues. The phones will heat up and start to lose 1% of battery as fast as every 2-4 minutes in standby. This is really awful.

I have no exchange email on any of the phones. Even so, on two of the phones I have deleted all email accounts (a pop3, gmail, yahoo and icloud) and reinstalled with no improvement. I restored my phone from backup with no improvement. I upgraded my phone to 6.1.1 and it made the issue worse.

My wife has a second work iPhone, a 5 and it does have Exchange on it and it has no issue. My son has a iPhone 3G and it has no problems.

Apple needs to fix this. I called them last night and phone support was not aware of the issue, which is frustrating. and doesn't seem possible. They cannot downgrade the phones to 6.0. I have an appointment at the Apple Store in a couple of hours but I am not hopeful.

Silly miss, Apple. And Enterprise acceptance was just gaining ground.

My iPhone 4S with 2 Exchange accounts was perfectly fine until 6.1.1. Now I lose 10% battery per hour in standby. Just tried deleteing/re-adding the Exchange accounts. HOPEFULLY this will work.

Hi.. 6.1.1 does not solve any battery draining or heat issues on 4s model.

After upgrade to 6.1 this problem started, even upgrade to 6.1.1 does not solve this issue.

Frustrating to see your phone battery charge 100% and die in 15%.
