I bought the MOPHIE changing pad for for my iPhone X and i'd say about half the time, it doesn't work. Has anyone else had the same issue? I lay it on the pad and sometimes it just refuses to charge. I'll adjust it, change the orientation, pick it up and put it back down, but nothing. and other times it works fine. Last night i had about 14% battery before bed and put it on there. Woke up to realizing it didn't charge at all and was down to 10% battery life. Of course i threw the box away for it and i'm not sure what to do. Obviously APPLE, which is where i purchased it, wouldn't entertain my issue, because i don't have the box. Right? should i contact MOPHIE? It just sucks, because it is a $60 product. I certainly don't think it is a problem with the phone itself. Any advice would be greatly appreciated.
