You are correct. USB A ports are usually only rated to 1500 insertion cycles because that is what the standard specifies. Micro USB and USB C ports are specced at 10,000 insertion cycles.
I am stunned to hear micro USB is rated for that many insertions. The implementation must not live up to the standard. In my experience, anecdotal, I know, microUSB is the most unreliable of all the USB form factors I've experienced. Bad connectors on cables, and ports that regularly fail internally (not levered off the board.) I have considered replacing ports with miniusb, or a tethered B port because micro has been such an utter failure on so many of my devices.
MicroUSB is supposedly designed in such a way that the stress is placed on the cable connector which is easier to replace, not the device connector which is attached to an expensive device.
But yeah, I can't imagine Micro-USB being more reliable than regular USB-A.
Yep, had several devices fail because of micro-usb going bad. And the worst part is that since it's how you charge it, there's no option not to use it daily (yeah there's wireless charging standards, but adoption is abysmal so far).
