iOS 6.1 Battery Life

Updated to 6.1.1 and still having problems.

Also my picture texts are taking forever to send, even though I'm connected to fast Wi-Fi.

What did you ever end up doing? Restore? DFU restore?

Can anyone who is having the battery issue confirm that they are NOT using the Activesync connector (Exchange) with their mail/calendaring service. Also, can anyone (again who IS having the problem) confirm that they are NOT doing recurring calendar events?

I have two exchange accounts and never had the problem with multiple calendar notifications. I just lost battery power quickly. For example, 89% down to 76% in a fifteen minute time span. I got so fed up with the phone that I did a clean reinstall. Today is the first day that my phone hasn't been attached to a charging cable. (Being that it took me a day to put my phone back together.) I will be using my phone as normal today, so I can keep you updated. JbRoch said that he deleted the exchange account, did a hard reset, turned phone back on reinstalled the exchange accounts. And after doing another hard reset his phone was working fine. Below is his account.

JbRoch stated:

I can confirm the below worked ! Back to my normal pre iOS 6.1 or 6.1.1 batter drain rates...

Just to point out the two devices are :

iPhone 4S iOS 6.1.1

iPad gen. 2 iOS 6.1

I used the steps I recorded below, the reboots at each step may be the key as anything corrupted will stay on the device till a restart is done to clear memory! Good luck to all of you this may not help. Some how I am not surprised Apple is still not caring about QA with Microsoft products......geese...

Fix I did:

i read some interesting references to Exchange being put in a bind over the upgrade, making repeated calls to the server looking for updates. This makes sense to me and recently got no joke, 10 separate notification of single meeting I accepted yesterday. I saw in the posts that folks had deleted exchange and reinstalled it and the problems with Battery went away. I have since deleted exchange on the Phone and Ipad and reinstalled on both. The steps I followed on both were:

Delete Exchange from device Then Shutdown/Restart

Reinstall Exchange on Device Then Shutdown/Restart

Phone is now charging for the 3rd time today! I promise to come back here and post the results of the tests soon. If in fact this is the culpret would explain why some folks are not seeing this problem as they may not have Exchange on thier devices!

From what I can see I did not lose any data by deleteing Exchange from the 2 devices

Keeping fingers crossed!

I am NOT using Activesync connector. My emails and calendars are either Google or iCloud, which I believe are not using exchange servers.

Some of the google / icloud calendars do have recurring events though...

However and despite what I affirmed on the previous page, it seems that since I deleted all my icloud / google calendars , the battery is no longer draining. Could some recurring events causing the issue ?

I didnt have any issue on battery draining before. after the update 6.1.1 (4S)..my phone battery does not even last overnight 😟.. awh . its draining as we speak..

Raechel, I know this may be asking alot... is there any way you can get your Exchange admin to pull the log files from the server of the interaction with your phone? Also, can you ask him if you guys have any load balancers and, if so, what make and model? Thanks...

Kristel, I'm thinking that the same API on iOS is being used. You're doing Activesync with Google, it's just not being called that.

Here's one thing that you might try: delete the Google "connector" to your account. Then do the following:

Set up IMAP for Google. Under "Add Account" select "Other" then "Add Mail Account". Make sure you select IMAP during the setup. If you want to set it up manually, the servers they use are "imap.gmail.com" for inbound and "smtp.gmail.com" for outbound.

Then set up a CalDAV account to Google to sync your calendar. Again, that's under "Add Account" / "Other" / "Add CalDAV Account".

See if that gives you your calendar and email while fixing the battery life.

Hello all,

I jumped on my outlook client and noted many sync errors on that end as well so it makes sense. The Active sync accounts were impacted by the upgrade and are constantly trying update causing the drains... The fix I did is still working.

The battery levels I had we're ok today 98% on the iPad and 33% on the phone that's pretty much normal for me, I have 4 or 5 mail accounts on each so that's a lot of cal sync to do :).

Yeah, there are indications that flattening (factory resetting) the phone still doesn't get rid of the problems but I'll be interested in seeing if JB's fix actually works. JB, have you added recurring events, etc., just to try and get it to flake out again?

Hi Joe yes I have as we are in the north east lots of meetings getting moved around due to the snow storms. I feel badly for anyone that went through all the **** of rebuilding there phones if it was this simple to fix.....grrrr what has Apple not said anything about this yet! It is all over the web! K

Not to get political or anything but it's just not the same company with Steve gone 🙂 They just seem so disorganized and unresponsive to consumers; and it's all happened in the past year. Marked change.

I don't know why but when I add my iCloud account it consumes a lot of traffic as well. And I have not enabled Calendar. Is this happening to anyone?

Now I can't have any emails, not even the ones from iCloud!

Am I the only one to experience a noticeable drop in battery time? I have 6.1 and don't use any Exchange account.
