[doublepost=1526091271][/doublepost]Hi Guys,
I havent read through every single post prior, but i do have some input into the black mark scenario. I chew through iphones and reviewed this thread prior to my last visit to the apple shop. I constantly break phones with the black mark and apple are shady when it comes to dealing with it. When i went back with my previous phone that was working they classed it as water damaged and refused to replace the phone that was under warranty, so i bought a new one and six months later the same thing. They then informed me i was classed by apple on there system as a high risk user. So i had to figure out what was going on, cause you dont want to be classified on there system in that category. They will not deal with you. I have done two things that have changed the situation in relation to my use 1, I do not charge my phone over night, like i did previously. The additional hours of charging through the port are detrimental. 2, I always clean off the cable pins before putting it into the port, i also put the charger in a drawer after charge. A lot of the time it was on the floor or carpet picking up fluff. From my experience, only charge the phone when it needs to be charged 1-2 hours every 24hrs. If you already have the black mark your phones on the way out, you've damaged the pins already. Flicking front and back when inserting the cable will only work for awhile, replacing the cable will only work for awhile. You need to change your phone habits to avoid the issue in the future.
