Secondary school students say using their phones too much is affecting their ability to focus and study.
A survey of 1,065 students, from 1st to 6th year, found 83% are worried they use their phones too much.
The research by Studyclix, also found 38% use their smartphone for more than four hours a day, an 11% rise on 2019 levels, 29% of students surveyed had the same usage levels.
The online study tool also found 16% spent more than six hours a day on their phone.
Co-founder of Studyclix, Luke Saunders, said social media is also having an impact on students' concentration levels.
"More than half (54%) said short-form video has damaged their ability to concentrate.
"When we look at the types of apps that they're on, Instagram, Snapchat, and TikTok, a lot of them are led by short-form videos, and as we all know, they can be extremely distracting".
One in five pupils surveyed said they'd used Chat GPT for schoolwork. The students said they'd used the AI tool to complete school-related tasks "including writing essays and creating coding questions".
