In other forums I've seen message passed by old time pilots about MM being critically flawed, scorning new MM users coming for help, something along the lines of: it's normal... you've bought a lousy product what did you expect?. There's nothing furthest from the truth and those people are just proving their small mindedness, beyond not helping out at all.
Concerning height problems when facing a wind STRONGER than the AC capabilities as already explained by some personnel at DJI the MM would gradually lose a little bit of height to get a better chance of standing up against wind. Not only at lower altitudes and near ground the wind almost always decreases but that offers a better change of retrieval if the drone is coming back more easily. If the drone would stand up to the wind (more powerful than its design limit) to it's maximum capability it would still end up being carried away indefinitely only to auto-land when the battery is empty.
Another thorny problem was this flying strategy being fused and confused with ESC related problems. Those are usually a good indicator of maxed out motors, and that is also a good indicator deeply tied to flattened or incorrectly shaped propellers. So far all the cases that I could notice where heavy ESC error rate was involved and in which a fix to change the propellers was applied managed to solve the problem. Not only that, I've seen reports of errors starting to appear later in life of MM in the hands of their respective owners, this means that at delivery the AC was most likely OK and props got warped with time and storage. It's very important not to ignore ESC errors as flattened props (and maxed out rear motors) are one of the main causes of height losses.
There's then the uncommanded descent, usually by a hanful of meters at most. That can happen when flying for several seconds full speed ahead and down in Sport mode. Pressure buildup inside the drone top bow chamber causes increased pressure readings to which the FC reacts accordingly, dropping the altitude and recovering a bit later when pressure reading evens out. This is a design limitation and not something that I feel particularly limiting.
Having an inaccurate reading at landing, for example some meters below the actual starting point, I think it's pretty much the norm due to the conservative way the altitude is calculated, I think to stay on the safe side both in term of atmospheric pressure variation and possible reading deviations.
I've never experienced any abnormality with my Mavic Mini concerning flights. I can just report good things about the little aircraft. Not only I've manged to fly 160 Km with it but also never experienced any significant error rate, I am pretty content with range and performance level.
DJI Care Refresh isn't replacing drones for free but you need a drone to bring back as it cannot cover fly-aways... which usually happen when: A: IGNORED Strong Wind Warnings, B: compass is initialized in a distorted magnetic field.
