Unidentified Internal Phone Part (iPhone 5s)

Upon opening my phone up to replace the battery, I pulled a little too hard with the suction cup and my phone popped open, detaching the home button cable and then sending the part in the image attached flying out of it. Nothing was damaged and the phone is working fine, but I cannot figure out where this part goes. (There is a slight chance its from something else I was working on earlier but I wanted to check with people on here first to be sure). If anyone recognizes the part and could tell me where it goes that would be great!
