Do you turn off WiFi in your house for the night?

No, I don't. About a year ago I set my phone not to disturb me from 22:00 o'clock to 7:00 o'clock. I already gpt used to that so there was no need to turn off the wifi. 😊

Yes. I also use the do not disturb and downtime features in my iphone. Those are all set for the same period of time each day. I disconnect.
