Hello, could someone possibly answer these questions I have about the Mavic mini?

1. What would be the range that would normally happen, I know it is advertised as that, but I find that usually it gets to around 30% of advertised.
2. Does the controller have a sport mode and an ISO wheel thing? And also does it have a way of letting the gimbal look down and up/inbetween
3. How long flight time should I expect in comparison to a Phantom 4?
4. Can I use DJI goggles with it?
5. Are there any other controllers I can use with it?

Thanks!

4. Can I use DJI goggles with it?
Someone post it here
5. Are there any other controllers I can use with it?
Just like other DJI drone, no you can't (The Smart RC is not compatible with it, Mini fly with wifi)
