The present study aims to identify the influence of smartphone use on the attention and academic performance of 4th grade adolescents. To achieve this, we used both quantitative and qualitative research tools to collect the data. These are the questionnaire and the Zazzo attention test. Academic performance was measured using scores on the French and math assessments. The results show that the students with the best academic performance are those who use their smartphones for less than 120 minutes (2 hours) per day. Students spend on average between 120 min (2h) and 240 min (4h) per day using their smartphone. Games and social networks are the smartphone applications most used by these adolescents. It is essential to make students aware of the disadvantages of abusing their phones.
