I am looking for a usb cable (usb A to micro usb B IIRC) to charge a
Samsung phone. One came with the phone but I'd like to replace it with
a longer one and I'd like a second to leave in the car.

I have bought different makes but they all fail after a while because
the metal micro USB plug becomes loose and waggles about in the
plastic moulding of the plug. The OEM plug is made of hard plastic and
does not suffer this problem (yet?).

Any recommendations for what cable will stand-up to repeated pluggings
and unpluggings?

Not related to the insertion count, but it's worth looking at the wire
sizes in the USB cables, as thin wires and long leads results in a
voltage drop that reduces the charging current.

The thinnest leads are 28 awg, 24 awg are thicker, and 20 awg are
thicker still. You'll often see something like 28/24 which means 28
awg for data and 24 awg for power.
