Slow Death cable Lightning: causes and consequences

In 2012 , September 12 , Apple announced

 the next iPhone 5 smartphone . Together with the increased screen , more powerful processor , updated camera module and a number of other " pleasant things" , users were revolutionary cable and Lightning. Lightning allowed cable to connect iPhone to a charger or computer both parties. 8-pin Lightning became the evolutionary replacement of the obsolete 30 -pin USB cable. But, as it turned out, this accessory can not " live forever ."

USB cable MD818 ( aka - Lightning), was sharply criticized by ordinary users. All claims related to the lack of strength and durability cord . 

A month ago for $ 19 I bought cable Lightning. A few weeks later I began to notice that when connected to a car charging my iPhone 5S refuses to charge. It was enough to move the cord and charging will resume . And a week later , even such "cosmetic" manipulation ceased to give any result . 

Cable finally stopped working.

Looking at the contacts , " the pope » USB Lightning, I found that several gold-plated contacts corroded .

However, this is not the only case . 

Beginning with the announcement cord Lightning in 2012 and until today , the number of defective accessories is growing exponentially . On the part of Apple, the indignant letters of users followed the same answer: " It is conceivable that Lightning cable is exposed to moisture ." Of course, in a review published by users of any one story is not related to " swim in the water column ."

There are two reasons why the cable Lightning fail :

1. Under the influence of moisture condensation occurs between the circuit " ground » GND ( 1) and «+» PWR ( 5).

2 . As a result of arcing contacts and break under the action of the current.

Despite the fact that the picture presented , where the contacts are sealed Lightning cord under the microscope , are visibly melting contacts , explain their origin in practice very difficult. In order to short-circuited , the level of concentration of moisture on the surface of the contacts must be very high , and the voltage and current in the USB cable simply can not create an impressive electric arc.

In the event of such problems with cord Lightning, Apple authorized center , you can replace affected by corrosion on a new cable .
