    I called as well and they told me to restore to factory settings.  I figured I'd try from the last back up when I upgraded to 5.1, since I was going to have to start all over anyway.   It worked from my last back up and the battery life is back to normal, if not better.   After initial 5.1 install battery was sucked dry, but the back up restore did the trick.

    could you give a few more details and steps to do what you recommend?  For those of us who are new to doing these Restore actions??

     

    thanks

    Andy -

     

    From iTunes (with iPhone present) right click "your iPhone".   Look for "Restore from backup" and click.  Restore from your last backup, which should have been done when you upgraded to 5.1.    Let it run through the process and it should get you to normal.

    iOS 5.1 has definitely prominet battery issues. After upgrading to 5.1 yesterday, drainage has been severe. Usage pattern has been same. Apple tech need to address the issue ASAP.

     

    I wish there would have been a simple "Rollback" button to previous versions of iOS.

    No problems here. Best battery life since I bought it. Great update in my opinion.

    Which utility app is that that you are using?

     

    Thanks.

    5.0.1 Was the best for me for battery life. 5.1 seems to be draining my battery out much faster. I also notice that when my phone drops below 50% battery life, it seems to start draining even faster. *****

    That's my experience.

    I have an iPhone 4. When I was using iOS 5.01 my battery would last all day even with hard use. Now with 5.1 in very light use it lasts no more than 4 hours. I notice that with 5.01 appls that used location services would turn off the Location search when they went into standby. Now, with 5.1 I have to manually kill the app or it will continue to run Location services and literally suck the battery dead in 2 hours. I have done a restore and this didn't help.

    The utility app I use is iSysMonitor.  It is no longer available through the App Store, but there appear to be several similar apps.  I see a couple of free apps called Activity Monitor and another one called All About iDevice that appear to provide equivalent functionality.  There are a few paid apps, as well.

    Similar trouble. I've a 3GS that on 5.0.1 lasted me for 2+ days usage for me (mix of WiFi at home, WiFi off at work, mail on manual, notifications off). Same usage after 5.1? Battery drain is severe - lost 71% charge in 3 1/2 hours, consistent with many above.

     

    Apple - this problem is too consistently reported to be inconsequential. Your release notes quoted "battery life improvments". Clearly this isn't the experience for many.

    I am having major battery issues since my 5.1 update. Personally I don't think we should have to restore when we update in order to make things work. I have experienced worse battery issues than before the update. This needs to be solved, as one of my main reasons for buying an iPhone was the better battery life!!

    I did the restore on my iphone4 and the battery will last all day.  However, I am a lite user.  I think what really bugs me is that I bought a great phone with a battery that would last a week. 

     

    Apple has unintentionally, I hope, sabotaged their own product.  I hope that they fix the problem before the iphone5 comes out.

     

    Just venting
