iOS 6.1 Battery Drain Problem

Added the correction, bought this 9/2011. Need sleep, I'm not proof reading or promoting their products, only trying to help. Sorry for the misprint.

And what about the connectivity issues (power supply or mac/pc) ? Are they present because of the push notifications? Maybe I should just constantly use my iphone and my ipad on flight mode. Best solution for my needs.

The issue is nothing to do with the settings.

Closing apps is a simple thing that the majority of iPhone users know how to do. I have always set push emails etc to off, reduce my brightness etc

It is definitely something to do with 6.1 as i had no issues previously & now experience overheating with ridiculous battery drain.

Don't know what to tell you, that worked for this tablet. I know little about the fones.

I think many mentioned that battery issue is especially linked to Exchange mail account. If you don't use exchange or don't have calendar sync enabled, you may not encounter this problem.

I dont have an exchange account & I'm still experiencing overheating & battery drain so the issue is something else or would be down to a few things..

i had the same issue. I updated my iphone 4s to ios 6.1 on Sunday 2/3/2013. Normally my phone battery lasted about day and a half. I charged it on Sunday night and by Monday noon it was all drained and shutdown. So I started charging it more often. For the next few days I had to charge every 2-6 hours! On Friday I was looing for some solutions and came upon the Exchange issue so I deleted my work email from the phone. This fixed the problem. I charged yesterday and after almost 20 hours of phone on, Wifi on, etc. I am only down to 75% of battery.

I am not putting my work email back on until this issue is resolved (incidently it was my work IT department that wanted me to upgrade to ios 6.1!!). I travel for living and cannot charge every 2 hours most of the time. In the meantime I can use Safari to check my work emails.

You don't need to delete exchange account, just need to disable calendar sync alone in your exchange account settings.

I actually firstly disabled my exchange calendar sync (that deleted local calendar entries) and then re-enabled it, my phone didn't encounter battery issue so far (20 hours already), I don't know if that could solve the problem, it may come back sometimes later, if that happens and apple not yet releases fix, I have to disable calendar sync.

ok,i have made manually email fetching and battery is amazing, standby 1day 9hours, usage 8 hours (music,3g wifi surfing the net and etc) and left 40%.

Well,going to see whether i am able to get a new one or not.Battery's draining like crazy although i turned almost everything off:(

The issue with iOS devices pinging the Exchange calendar server in an endless loop was/is serious enough for Microsoft to recommend to network admins all over the world to restrict ALL iOS users. Apple keeps getting their Exchange server settings WRONG. this problem almost killed my 4S. Not going to update my mini until Apple fixes this.

I recommend TURNING OFF the calendar in ALL Exchange accounts.

I also hope Apple will stop flubbing this Exchange thing. This is at least their third SNAFU!

So many people here liken the battery problems to their Exchange account. I only use my Yahoo mail, and I still have the battery drain. I have never used Exchange in my life. So I am proof that the problems not only limited to exchange users.

Thats exactly what I've been saying. It isnt just down to having an exchange account. I dont have & i am suffering from mass battery draining & crazy overheating, even when only one or two apps are open.

Scott...you may be an exception. I have MULTIPLE accounts, including a Yahoo! Account. Th CURRENT overheat and battery drain problem is 100 percent an Exchange issue. I would bet a 50 spot that yours are related to the fact that Apple resets all accounts to PUSH instead of FETCH. Additionally, you probably have several apps that are ON in location services. There are several of those that are known battery hogs AND are having iOS 6.1 battery drain issues. Check some of the other forums! The BIG problem, this time, is Exchange. It was taking 10 percent of my battery every 15 minutes in standby. Turned off the calendar and...viola. Turn off your calendar in yahoo and see what happens?

@Brojim62

Well my push is set to OFF & set to manual on all my email accounts.. I've not got an exchange account AND calendar has always been off, yet my battery drains badly & overheats, so it may be a number of problems and not just exchange accounts.

Otherwise why am I badly suffering from this on my iPhone then?!
