Iphone 5 Cant hold charge.

Hello everyone! Sorry I'm new here but I'll try and get as much information on here 🙂!

My Iphone 5 32g has been having massive problems currently and I would hope that I would noyt have to take it into the Genius Bar until compelte last effort.

So what is happening as of now is that my phone will shut down randomly, and also for some reason will not keep a charge even when it is plugged in. I have tried countless restores, and everything I can think of in the book, but nothing is working for me! If anyone could give me some insight to my problem I would appreciate it!
