It is reasonable to ask for phone-free time, and it does not have to be controlling if you frame it as protecting time together. Use I statements and make it about the connection you want, not what they are doing wrong. Something like, I feel a bit disconnected when we're both on our phones at night. Would you be open to trying a no-phones window after dinner so we can actually hang out. I do not want to police you, I just miss you.
Pick something realistic to start, like 30 to 60 minutes after dinner or the last hour before bed. Put both phones on a charger in another room or in a basket, and turn on Do Not Disturb or Focus mode with allowed contacts for kids, work, or emergencies. Agree on clear exceptions, like replying to a time sensitive message, and a quick heads up if someone needs to step out to respond. Treat it as a two week experiment and then check in about what worked and what did not. Ask what your partner needs too, like 20 minutes of decompression scrolling right after work, and plan that in so the phone-free block feels fair. If a full hour feels hard, start with no phones at dinner only and build from there.
