That's over 13 cycles/day for two years. Probably fine for most users.
Edit: The official spec is only available via a zipped folder of PDFs, here's the particulars to save readers the effort.
Durability or Insertion/Extraction Cycles (EIA 364-09)
The durability ratings listed in Table 5-16 are specified for the USB 3.1 connectors.
Table 5-16. Durability Ratings
Connector Standard Durability Class High Durability Class
USB 3.1 Standard-A connector 1500 cycles min 5000 cycles min
USB 3.1 Standard-B connector 1500 cycles min 5000 cycles min
USB 3.1 Micro connector family 10000 cycles min
The durability test shall be done at a maximum rate of 200 cycles per hour and no physical damage to any part of the connector or cable assembly shall occur.
Whenever I leave my desk, I take the phone with me so that the Health app can record steps and distance. Thus the phone comes with me on bathroom breaks, so that's a couple more.
I'll go talk to coworkers down the hall a couple times a day, adding a couple more cycles.
Every 30 minutes I get up and take a stroll around the office to mitigate the effects of sitting too long . That's another maybe 10 cycles.
That's 17 cycles/day on work days, assuming no more cycles at home after work.
If I manage to have 6 more cycles at home on weekends or after work on work days, that will be bring my average over the week to 13 cycles/day.
The original 30 pin Apple connector wasn't bad, but when I looked at the new lightning connector I thought it would be a clear improvement. But now I'm not sure.
Lightning pins are quite small. I find my devices don't always make good contact. I find black stuff (oxidation?) building up on both pins and sockets.
Compared to lightning, USB-C just "feels" like it will be much worse. I predict it will be a disappointment in the real world (as most connectors turn out to be).
I've not been surprised to see how slow the adoption of USB-C has been because I think it's obvious to insiders that the reliability issues are real. The shame is that when it works, it's great.
