My just felt into 1 m deep water. Being there 1min.
I am dying it but the problem is that the battery can't be simply removed like with drones.

Well if it hasn't caught on fire that's a good start. But no, it is not water resistant at all. I would think there will be water ingress at the USB-C port and the card port at least.
