Don’t expect a Saturday tweet from Aviva Drescher. When the author and former “Real Housewives of New York” star found herself paying more attention to her 30K Instagram followers than her banker husband, Reid, the couple made a strict rule: No digital devices all weekend.

The unplugging policy went into effect last spring, and Aviva, 45 and an Upper East Sider, says it’s been challenging but worthwhile.

“I’m not going to say it’s easy,” she says of powering down. “But it increases verbal communication . . . we laugh more and fight more. And that, in the end, is what makes [our marriage] stronger.”

More and more people are making unplugging a priority. A 2014 nationwide survey by market-research group CivicScience found 20 percent of people unplug for at least a few hours a day. A recent Kickstarter campaign for the Light Phone, a credit card-size device that only makes and receives calls from authorized numbers -— it doesn’t text or tweet -— has received nearly $500,000 in backing, more than twice the founders’ goal.

Deb Castaldo, an NYC psychotherapist and the author of “Relationship Reboot,” says the trend is a healthy one for those in romantic relationships.

Without our phones, we can really focus on each other. - Brian Hanley, on unplugging

“A lot of New Yorkers thrive on constantly being in touch and connected,” she says. “But the more they’re always available to everyone, the less they are to their significant other.”

Two years ago, uptown couple Brian Hanley and David Rosenholtz, both of whom work in p.r., realized their devices were becoming an unwelcome third wheel. The started leaving their phones home every Sunday, and it’s strengthened their relationship.

“The best days we’ve had have been because of our lack of communication with the outside world,” says Hanley. “When we have our phones, it’s too tempting to snap a picture or respond to a text or scroll through Twitter. Without our phones, we can really focus on each other.”

But Rosenholtz, 28, admits that it can be a struggle. “We’ll wander across town and find a cute cafe and of course, my first urge is still to Instagram our order,” he says.

But their off-grid hours have had unexpected side effects.

“When we began tech-free Sundays, we’d turn on our phones and get panicked texts from friends and family, thinking something horrible had happened to us!” laughs Hanley.

Cynthia Inácio, 30, and Clistenes Pinto, 34, wouldn’t be together if it weren’t for designated unplugged times. When they started dating five years ago, Inácio told her new beau it was her or his digital devices.

“I liked him, but every time we sat down to dinner, he would pull out his phone and begin texting! I come from a European background [where taking a phone out during a meal is a big no-no], and to me that was a deal breaker,” says Inácio, who works in marketing and is originally from Portugal.

Pinto chose the girl over the gadgets and the couple continue to have a strict no-phones-during-mealtimes rule.

“Often, we’ll sit at the table for hours, talking,” he says. “We get lost in conversation.”

“We focus just on each other,” says Inácio.
