A little over a week ago the power adaptor that came with my iPhone just stopped working one morning. No idea why. Tried all other outlets and my lightning cord worked with a LG USB power adaptor I had laying around. On Thursday I took it to the Apple Store and they replaced it without question. Yesterday there was a bunch of static whenever I'd go back to my iPhone while it was charging, though there was still static other days. One of the several times it shocked me when picking it up it just stopped charging then after that the wall adaptor ceased to work once again! I could take it in again, but I don't want it to break for a third time. Anybody else have this happen or suggestions on how to prevent it? Hopefully it's not something wrong with my iPhone.
