I have been experiencing issues with my charging port on my 6 plus for the past couple of months now. Every lighting cable (apple certified) that I use has the message pop up that states "This cable or accessory is not certified and may not work reliably with this iPhone". This started to happen a couple of months ago, but It never dawned on me that the issue could be with the phone itself. I always blamed it on the cables. In result, I have purchased 4 new lighting cables from the Apple Store and all four cables give me this message. Also, I have noticed that the Lightning cable is easily removed from the phone while charging. Sometimes, it actually falls off if the phone is charging and placed on a flat surface. Today, I ran a test comparing both my phone and my wife's 6. I placed the same Lightning cable on both phone and her 6 held the Lightning cable in place like a champ. Mine took "very" little effort to remove. Has anyone experienced this strange issue that I am experiencing ? I made a genius app for Sunday, so I hope that there is some sort of resolution for this annoyance.
