I usually do this every night when I’m about to sleep, and also during times when I want to decompress from the barrage of notifications. Sure, DND mode is a thing but I really enjoy the feeling of being unreachable sometimes. Having it on DND still makes you receive the notifications. It’s also easier than turning your phone on and off. Regarding emergencies, I really don’t have any situations where it’d be so pressing for me to react immediately to something. And either way I’d never sleep having volume/vibration enabled from calls.
Is there anyone that relates to this?
Tbh I don’t really have any emergencies I can imagine necessitates me responding in the middle of the night. But I guess it depends on one’s life.
One thing to consider might be a literal emergency alert. But I guess the frequency of those really depends on where you live.
