iOS 6.1.2 Battery Drain on iPhone 5!

I have the iPhone 4S. I updated last Sunday (Feb 17) to 6.1.1. This is when I started seeing battery drain. I was traveling on Monday (which makes my iPhone use not normal, so battery drain wasn't really noticed, but on Tuesday, it was very noticable. I also noticed the update to iOS 6.1.2, which mentioned the battery drain issue, which I was having, but updating didn't do any good. On my return flight, in 2 hours, I went from 95% to 78% going through securty (no phone use at all), then on the 2.5 hour flight, in airplane mode, listening to music the entire flight, it only droped to 72%. Waiting for the connecting flight, it dropped to 40% (WOW), but then again, while on a 40 minute flight, it dropped to 48%, while listening to music. But just waiting to get off the plane (making a call for my wife to meet me up from, then a couple of texts), it dropped to 38% before I got off the plane, it was at 4% by the time I was home.

I have reset it many times. No problems before the update. I also updated my iPad to iOS 6.1.2, and it's having battery drain too, but neither my wife's iPhone 5 or her iPad are having the issue, since she doesn't update her iOS, without my help. Lucky her, no battery issue, but this clearly points to the NEW iOS update.

I did read that the iOS 6.1.3 is in the 2nd Beta releast, hopefully, this will fix (or undo) the latest problems.

my numbers were off, it dropped 10% while deplaining

I think I found a solution. I know that the problem in 6.1.1 had to do with Microsoft Exchange so I tried removing and reinstalling my exchange account.

It seems to have fixed the problem for now! I wrote a little post on how to fix it: http://bkbeachlabs.com/blog/ios-6-1-2-battery-issue-solved/

How many of you people have Exchange accounts on your phone?

That information been out there for sometime now. And people using there Exchange account is what is draining there battery life. Microsoft exchange server is not playing nice with iOS.

The information has "been out there for some time" about those with an exchange server issue, however, many of us don't use exchange servers at all and are seeing off-the-cliff battery drain. To repeat, the latest update is when we non-exchange useres saw the battery drain problem arise that we didn't have before the update. I've brought my iPhone5 back to normal by turning off push email and moving to manual. Looking through all the posts on this issue it appears push is the problem for some of us, and others have had remission after standing on one foot and howling at the moon. Of course I say that tongue-in-cheek because we've spend hours fooling around with the problem, and if it goes away whatever we were doing at the moment gets credit. For now, I'll turn push back on should Apple acknowledge and resolve the issue.

Same thing after updating to 6.1.2 yesterday. Battery draining at twice the normal rate. Today, down to 1% by late afternoon, and i hardly touched it. Normally, i use about 4,000 minutes per month. I noticed the Idle Time and the Usage Time were the same - I checked again, after putting it to sleep for a while., same thing. Here's what fixed it:

1. Turn off WiFi
2. Turn off BlueTooth
3. Turn on Airplane Mode
4. Go to Settings > General > Cellular > Scroll to bottom...
5. TURN OFF "iCloud Documents"
6. Turn off phone
7. Turn back on, and use wifi, etc... as normal.

I suspect the iCloud Documents is the culprit

It's been on 88% for about 20 minutes now, even with my checking the stats and messing with it

Thanks, Aaron

Thanks runr25,

I think you are right with the Icloud documents.

Despite your advice I just turned iCLoud Document off. (I did not touch any other settings')

I even did not restart the phone.

I've not lost any percentage off battery in the past hour. Before I would have lost at least 20%

I followed all the steps and that did the big difference.After I completed your steps then I also turned off Wi-Fi,Bluetooth(I never have it turned on),iCloud Documents and then turned on Airplane Mode.I restarted iPhone and it works a lot better(about the battery).Of course I turned back to my normal preferences.Thank you so much,I appreciate it.Keep on helping people.

up to 9 hours, myipod touch battery remain 100% (standby), previously reduced to 70%, turn off the documents in the cloud, location service, bluetooth, disable email push, fetch manually, and Advanced set to manually, tk ... and it works for me...

I never had a problem with battery life on my iphone 5 until ios 6.1.2. Now I can't even go the whole day without recharging. I literally saw my battery drain 5% in less than a minute on wifi. Looks like a trip to the Genius Bar is in order.

just go to settings and under "cellular data" turn off iCloud Documents. that's all you have to do

I looked under cellular and don't see "iCloud documents". Where exactly is it located?

Theres actually a couple solutions that have been working for people. Basically the update caused some random processes to keep running over and over, causing your battery to constantly drain and phone to heat up. They all seem to have to do with network activity: Push email, iCloud Documents, Microsoft Exchange accounts, Facebook, etc.

Heres the complete explanations: http://bkbeachlabs.com/blog/ios-6-1-2-battery-issue-solved/

I tried it and lo and behold, it worked! Although I just deleted my exchange account from my phone completely as it was an old school e-mail account. Thank you!

Why the reset all settings?? Can you please explain what this does? I've also heard reset network? Why are we suppose reset the device? Why are Apple batteries so messed up? We should just plug it in and charge it, right? What's with all these steps just to charge it? Is it because Apple won't admit that after iOS 6.0 it's been one crap update after another?

None of those steps work! Your a fool if you fall for it....lol. Come out with a real fix for the battery!! Wish I never bought the ipad mini....what a waste of money!!
