Does zagg cover my warranty if my invisishield was damaged while in another “hard case”?

I have had my invisishield installed on my iPhone for a while. I bought a mili power pack to extend my battery life. I didn’t remove the invisishield and I put my phone into the power pack and then it got stuck. Then I tried to take it out of the pack and it was stuck. I pulled it out but the shield was damaged. Does zagg cover this?
