That leaves 2h30 between you finishing work and putting the phone down. It’s not even like @jamwt said “go to bed at 8:30” or even “no screens at all after 8:30”, just put the phone away and chill.
8:30's about when dinner's been cooked, eaten, the kids are in bed, and about 50% of the day's mess has been cleaned up (you'll get the 250% of a day's mess that remains, after 5 week days, cleaned up on the weekend—at least, that's the lie you tell yourself)
I get almost no personal screen time—or other personal time, for that matter—before that (aside from time I steal to post on HN, like everyone else)
