iOS 5.1.1 have batery loss

I see the same issues, having my iphone since 5 month now. Until 5.1 everything was OK with it in regard of battery usage. Now after updating to 5.1.1 the battery lasts 5 hours from 100% to 5 %, doing NOTHING with it.

Apple deliver a solution.!!! And please - I need calendar syncing, and why does it work before 5.1.1? There is something wrong with Apple not with the user.

my ipad 1 and 3 are fine with 5.1.1, but iphone is a mess!

Apple is NOT going to deliver a solution. And Apple doesn't hear you when you post in this user to user forum. But, if you read the thread you have posted to you will learn how others have fixed the problem themselves.

I have the same problems with my iphone 4. Ever since I updated to the latest software my battery drains without even doing anything. And when I use it web surfing or phone call it drains like 1% a minute.Also anyone else having audio quality issues? I have problems hearing people on the other end of the line. My iphone was fine before this. I reset my iphone an let the battery die then charged to 100% last night also deleted a bunch of apps nothing helped still having the same issue. And my phone is no longer under warranty. I wish I had not updated to this software.

I reinstalled the connection to my Exchange 2003 server. After the install I changed the connection from push to fetch each 15 minutes. The phone is back to regular now.

I have had this problem since 5.1; it has always been intermittent for me though... The initial version was running great.. I upgraded to 5.1.1 just yesterday so cannot really speak for it..

Lawrence Finch has it right. An even quicker way we have found to reset the Exchange connection is to go into the Account settings for the Exchange account and turn off SSL and then save it. Then go right back into it and turn SSL back on. This will also make the iPhone resync everything with the Exchange accounts and resolves issues with fast battery drain and hot iPhones.

That's a great tip! I'll try it next time the issue occurs (and I am sure it will occur again).

Thanks for this.

F**king 5.1.1 update! Now my iphone became hot even in light usage and drain battery about 1% per minute! Is it any possibility to downgade to 5.1? I was perfectly fine. Now I can't understand WHAT to do and WHY I need to d osomething with this PEACE OF ART!!!!!

Kinst, do you sync to any Exchange accounts? If so, have you tried the solutions recommended here?

Never. Just usual IMAP with manual checkin.

I have recently discovered that if i switch off my wifi and internet the battery life is amazing. I too have got awful draining problems as much as 20% an hour I have tried everything and the only way to stop it is to cut internet access. I know this isnt a solution but I do feel something is constantly connecting via wifi and draining the battery. from Experience as a computer technician its acting like an old fashioned dialler that used to run up your phone bill except this is draining the battery. I Have never used exchange or any email on my phone so thats not a possible fault. However the update could have exploited or activated a bug which keeps trying to access the internet running in the background. A simple experiment is just turn off wifi and internet access and wach the draiage....

Do you have a lot of apps running? I have noticed that periodic killing of unwanted apps helps. Also, if you have facebook etc connected with push notifications on that impacts too...

No apps, I clean them as soon as I do not need them. No pushes. No Facebook.

And again - nothing was changed after 5.1.0

Ok .. Let's try and find some common things about the sufferers here.. If you are suffering, did you upgrade via iTunes using a cable, itunes wirelesly or OTA (wirelessly from your handset without iTunes)? I'm suffering from battery drain and I upgraded OTA.

I updated wirelessly (3 phones) no problem.
