Hi, I've put iPhone, iPad and Watch on the silent mode. Today at the end of the day I still have on my watch around 70% battery. So I didn't put the Watch on the charger. And I would like to know If I can use the Watch another day. But there is a thing. I was watching a movie and left all those devices on the table and turn the silent mode off on the Watch. I thought that If I get a message the Watch would get a notification and play me the "ping" sound. But it didn't. Do I have to set something or this feature doesn't exist?
