What is this part named?

I’m looking for the name of the part that goes directly over the battery. There are 2 pieces of black plastic that has to be removed to get to the battery. I had to replace the camera and my dogs grabbed these pieces off the table and they were thrown away not knowing the phone had to have them! On you tube the video of the error of phone temp too low and the yellow triangle with the exclamation point, started this was an inductor but I cannot find that anywhere!! Help!!!
