I’ve never damaged my own phone. But just yesterday I went to Apple to have them replace my battery. The genius guy ran the diagnostics and told me the battery was fine. I explained that it wouldn’t make it through the day and I would pay for the battery replacement. He looked over the phone carefully and we both agreed that there were only minor scratches on the bottom edge. When I got my phone back it was scratched to heck on all the edges. He went to his manager, came back and offered me the battery replacement for free. I explained that I make it a point to take care of my phones and put them in cases and always put on a screen protector.
They ended up giving me a new phone.
