Apple Watch drop standard

The fall detection function of AppleWatchSeries4 is to use the motion information provided by two new sensors to analyze the wrist motion trajectory and impact acceleration, judge whether the user falls, and then start the help function.

When the watch detects that you have fallen, it will take about half a minute for the watch to further judge your situation at this time. If your fall is not serious, and you can still walk and sit by yourself and have the ability to call for help, then the watch will not judge this action as a fall.
