Answer 1

As you say, it's very, very likely that the problem is the battery of your iphone. 

 

Let's go slowly, directly connected to the current look and see if at least load, usually took a while, since I guess it is now no battery drop. 

 

When you do this test and depending on the result I'm saying.
