Interesting... I knew the X4S was the exact camera as the Phantom4Pro v2, same mechanical leaf shutter making it an ideal choice for survey, geo terrains & mapping. Hadn’t really looked at the X5S or X7 specs regarding mechanical leaf shutter. Interestingly the X4S and X7 have mech shutter below 1/1000 and the X5S is solely Electronic.
I just recently purchased a X7 & 4 Pak lens set... due this week! Which was even more interesting to learn regarding shutter. Since the X5S was electronic, just assumed the X7 was too, and the mechanical was reserved only to the X4S. That provides a new light... another operation the X7 can be used for... although it's a pretty pricey package for survey photos when the X4S works great.
I haven't found the APP "switch" or menu value to turn OFF. But I did find on DJI site... the Mechanical is ON by Default up to 1/1000, and the Electronic does not function below 1/1000 unless the Mechanical is disabled. It's not a could be either or situation, it's a one or the other with Mechanical default.
I would then assume, unless you've disabled... it will always be mechanical under 1/1000s with 3 of the 4 lenses. Not the 16mm lens; the 16mm lens does NOT use Mechanical and will always use the Electronic.

8.How does the leaf shutter work? What are some of its benefits?
When the shutter speed is slower than 1/1000s, the leaf shutter will be automatically enabled but can be manually turned off. The leaf shutter prevents image distortion caused by rolling shutter, stripes resulting from artificial lighting, and motion blur when shooting high-speed objects. Currently, the leaf shutter is only active in Single Shot mode.
As the market leader in easy-to-fly drones and aerial photography systems, DJI quadcopters like the Phantom are the standard in consumer drone technology.
