Honestly, the same day I upgraded to the latest iOS, my phone started shutting off with 60% of battery remaining, and will not successfully boot up unless I plug it in. When I plug it in, the battery shows 60% or so remaining. I charge it fully, and situation repeats. If I'm using power hungry apps, I'm good for about twenty minutes. In stand-by mode, I'm good for about six hours before it goes dead.


I recharge fully every night. I tried restoring the software. No effect.


Am I alone in this? Is there a fix?

iPhone 3GS, iOS 5.1

    I have the same problem.  Heard there is an issue with trying to back up an I-Pad and an I-Phone off the same PC.  I've tried all the fixes posted on the various websites short of trashing the firmware.  Does Apple have a solution!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    My 3GS is more than one years old and my iphone 4 bought last st 2011. Both were fine until I upgraded to iOS 5.1.

    I'm having the same problem; not sure when it started happening, perhaps when I did the upgrade.  I've done everything suggested, reset the phone, etc.  So the only solution is to go to the Apple store and get a "service trade"?  Is that what I should ask them for, noting that I've tried everything else?  Thanks.

    Would they still do a service trade if it is a secondhand iPhone

    My 3GS 16Gb iOS 5.1.1 keeps crashing also; been going on for 3 months and I've been trying to figure this out (quite frustrating!)  All apps are not running, typically has 50% to 75% power remaining, and sometimes happens when I am using the camera (video) and sometimes using an app like Skype IM, plus others -- the whole screeen goes dark and I have to press the silver button to boot it back up again (which takes several minutes now).  I want to wait until the next iPhone (5?) comes out rather than buying a 4s now.  My guess it's memory or cpu intensive apps, but can't tell for sure.  I think it's a bug in iOS.  Does anyone suggest how to narrow this down, maybe a monitoring app that can be used and we can exchange notes to narrow this down?

    So, once again I restored my iPhone to no avail (in fact, it seems even worse now).  Wondering if it's possible to go back to the OS before 5.1.1?  I had no problems with that one.  What number was the one before this one, just 5.1 or in the 4s, and can that be done.  I have absolutely no use for the goodies on version 5.1.1, especially if I can't use them anyway?  Thanks.
