Durability of USB ports and plugs?
« on: January 10, 2019, 05:11 PM »
Things like microswitches and camera shutters have a rated life of so many actuations.  Is this also true of USB plugs and ports/sockets?

Wiki: USB (Physical)w

Standard USB has a minimum rated lifetime of 1,500 cycles of insertion and removal, the mini-USB receptacle increases this to 5,000 cycles, and the newer Micro-USB and USB-C receptacles are both designed for a minimum rated lifetime of 10,000 cycles of insertion and removal. To accomplish this, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection. This change was made so that the connector on the less expensive cable would bear the most wear.

As always, this doesn't take into account abuse and quality.

So, in theory, the standard A socket at the computer end will fail before the end you plug into your phone. :)

Limiting our insertion and removal would make the USB ports and plugs to last longer.
Even if that isn't possible then reserve one port from multi using so that it would be helpful during the worst situation.
