I share this tip this week because, for the third year in a row, I find myself having the same problem. It seems that the Lightning Port of the iPhones 6, 6S and 7 all have a particular attraction to lint. Since I wear jeans to work most days and keep my phone in my front pocket, this lint build-up is inevitable and always seems to pop up right about now. However, it is easily remedied if you know what to look for.
