Yes, my teenagers have time limits are they aren't adults and haven't graduated from high school yet. My adult children have no limits.
There are no cell phones after bedtime, we have a main charging station in the living room where they get "parked" before bed. There are no computers in their bedrooms and if we are having family time, all electronics are off - cell phones, ipods, ipads,etc.
Everything is off at meal times. And no phone calls or texting during homework time unless it is specifically about homework and as we pay their bill, we will look at text content if necessary.
