A year of plugging it in once or twice a day to recharge it, and it blew.

Old rectangular USB-A was only rated for 1500 ideal insertions. USB-C is a big improvement at 10,000 ideal insertions. Most insertions are not ideal, and it is relatively common to have some leveraged pressure trying to wedge the port apart; When my phone bridges the gap between the arm of the sofa and the coffee table while plugged in, for example, it's got a bending moment. USB-C is much thinner in the up-down dimension than USB-A, and it is not designed to safely disengage when side-loaded like Magsafe. If you wanted to break it for some reason, I'm pretty sure you could do it in a few seconds while resting your elbows on the table, on grip strength alone.

It's a narrow connector and sideways force acts like a knife on the shell. blowing out the sides. and then the connector is unreliable. It is better than microusb but worse than usb-a.

So it depends on how you baby it, but a few good accidental tugs can ruin a phone.

I like to run my game controllers wired and ruined one(xbox-one controller) this way when I got a bit agitated during a game, it's replacement(8-bitdo wired) is much better designed where the plug housing goes in a snug inset in the controller. Providing strain relief. I dread having to find a new plug that fits if it goes bad. but a narrow plug should work, granted without the strain relief.

My old Sony xz2c's USB C port wore out after about three years use. About the same length of time they bothered to update Android. :/
