While with me Apple charger always lose their insulation in the transition from cable to plug occurs to me in general in our collection of USB Micro charging cables on that these hang loosely over time in the micro-jacks and partially little train even fall out. I do not know why that is. Whether these small barbs debt bear? Lyres from?
What food are also those experiences?
It's not the socket itself, as other cable lock bombproof. For example, the System-S data cable with 90 degree angle plug.
