The 26-year-old pop star has been inspired by a recent Silk Sonic gig in Las Vegas, where fans' devices were locked away, and she loved the "beautiful" atmosphere it created.
Asked if she would consider similar moves to Silk Sonic, Adele and Madonna, she told Rolling Stone magazine: "This will honestly piss off my fans, but absolutely.
"Because I went to see Silk Sonic in Vegas, and they locked my phone. I've never had a better experience at a concert.
"I genuinely felt like I was back in the '70s - wasn't alive. Genuinely felt like I was there. Everyone's singing, dancing, looking at each other, and laughing. It really, really just felt so beautiful."
The Manchild hit maker pointed out that phones being held up at concerts "feels super normal" to her generation.
"I've grown up in the age of people having iPhones at shows. It unfortunately feels super normal to me," she said.
"I can't blame people for wanting to have memories. But depending on how long I want to be touring, and what age I am, girl, take those phones away.
"You cannot zoom in on my face. Right now, my skin is soft and supple. It's fine. Do not zoom in on me when I'm 80 years old up there."
