When you buy a new Mavic, it comes with cables to connect to your device and also a separate micro usb cable to charge the controller. Many owners use the micro USB port on the controller for both data and charging, and based on my experience repairing controllers, it's best to use the USB port on the bottom of the controller for data while flying. I recommend reserving the micro USB for port on the side of the controller for charging only. If you break this port, you wont be able to charge your controller, you cant charge from the bottom port.
The problem with the micro USB port on the controller is that it is more fragile than the bottom port. I have repaired so many of them, I have determined it to be a weak spot on the controller. If you do break the port, you will need to replace the entire 5 way switch board, there is no other shortcut. The board itself is not overly expensive, but to replace will take you or a technician an hour to do. Labor + part can easily be $60 - $100.
What I do is use my USB C to USB cable and plug it into my bottom port. I use an extender anyway, because the jaws of the controller wont fit my S8+ with the case on, so I cant really use the supplied short data cables that DJI supplies. The bottom USB port is very sturdy, and I have never seen one go bad.
Below is a picture of what can happen to the micro USB port after a few dozens charges. The tongue inside the port simply snaps off, then it's too late. Cant charge the controller and need to repair it.
One last thing. I mark my micro usb cable with a "t" on the plug to tell me that its the top of the plug and the t needs to be facing me before i plug it in.
That's my 2 cents worth of advice for this morning. Have a great day!
