You don't want to be bothered by notifications and incoming calls from the app on the night of the day when you get tired of work, right? In such a case, iOS "Good night mode" is what you want to take care of. It is activated by tapping the button in the control center, and you can spend your time slowly until morning without being disturbed by the sound / vibration of notifications and incoming calls.
In iOS 12, that "good night mode" has been enhanced. Until now, it was supposed to be used at night as the name suggests, but it can now be used conveniently even in the daytime, such as enabling it only during events registered in the calendar.
Depending on your ingenuity, you can use the function to cancel the sleep mode when movement is detected. If you want to relax at home regardless of the time of day, do not want to pay attention to the iPhone when eating at the store, set the sleep mode to OFF when movement is detected, it will be automatic when you leave the place Notifications / incoming calls will be notified as usual.
The operation is easy, just tap and hold the "Good night mode" button on the control panel and tap "Until you depart from this place". This item does not appear just by tapping it, and it will be the normal setting that the good night mode will be canceled the next morning.
If you use this function while traveling at high speed by train or car, it may not work as expected. In fact, when I tapped "Until I depart from this place" when I got on the subway, the good night mode was turned on, but it never turned off no matter how many times I passed the station. Overconfidence is prohibited because it will not turn off automatically unless you move with vibration, such as walking for several tens of meters.
