For the past couple of weeks I have been having problems with the charge on my iPhone.  It also has been very hot and needing a full charge every few hours.  Yesterday I took it off charge and three hours later it was at 20% charge.

After trawling through the countless pages of internet pages on this problem, I decided to do a full restore and back up of my iphone  (I'm running iOS4.1).  I have no location services on, I have no push notification services on, and I have made all my emails set to manual, not that I know why I have done this because this has not been an issue before.  So then I read into that multitasking bar thing when you push home twice and clearing out the apps from there and seeing how I go.

So overnight I left it to charge, because of course it was dead when I went to bed, and I pulled it off charge an hour ago, haven't checked email or anything like that, and just left it sit on the bench while I sort my children out for school.  Its dropped 30% in an hour and telling me that my usage and standby time is the same, but can't really say what this was before, or if it even means anything.

I guess my question is; is there something else I can  try, or am I just better taking back in to VF and getting them to get it sorted, as its still under warranty (I got it in December 2009, and has been replaced due to hairline cracking).  It's only been something that I have noticed in the past couple of weeks, and haven't plugged it into the computer in that time, and wondering if there is an application running in the background that I can't shut down.  I have deleted all the applications I have downloaded in that time to see if that helps, but doesn't seem to have made a difference.

Any ideas or help on this would be great - thanks :)
