Statistically signifiant diffrences were observed among adolescents concerning gender, grade, daily smartphone usage duration, internet accessibility, and the use of smartphones before bedtime, impacting both sleep quality and smartphone addiction (p < 0.05). A positive and meaningful correlation was found between sleep quality and smartphone addiction in adolescents (p < 0.05). Conclusion: As the smartphone addiction increases, sleep quality decreases. Adequate sleep is crucial during the growth spurt period. It is evaluated that early diagnosis and prevention of smartphone addiction in adolescents could make a signifiant contribution to the protection and promotion of adolescent health.
