I've been searching for information about USB connectors durability and I have found those numbers:
- Type-A: 1,500 plug-unplug cycles
- Mini-A: 1,000 plug-unplug cycles
- Mini-B: 5,000 plug-unplug cycles
- Micro-B: 10,000 plug-unplug cycles
- Type-C: 10,000 plug-unplug cycles
What this data is lacking is information about which side of the connector has this durability. For example fragile bending parts were intentionally moved in micro-B from socket to plug to put wear on cheap cables instead of soldered elements. Does it mean, that after 10,000 cycles only the plug will fail? When will the socket wear off? If the numbers describe the more durable side, is there any data about type-A socket? Usually it's permanently soldered into expensive hardware, but has waring spring mechanism, so that seems important.
