A recent study from the Seattle Children’s Research Institute (SCRI) found that students spend about 25% of the school day on their phones.

“The research revealed adolescents spent an average of 1.5 hours on smartphones during their 6.5 hours of school, accounting for 27% of their average 24-hour phone use,” according to the SCRI study.

SCRI researchers recruited and tracked teens’ cellphone activity countrywide and analyzed the data.
