Smartphone addiction in adolescents is defined as excessive mobile phone use (>2 hours/day) that negatively impacts sleep quality. Exposure to blue light from smartphones inhibits melatonin production, increases sleep latency, and triggers bedtime procrastination. Globally, 25-33% of adolescents experience problematic smartphone use. This study aims to identify the relationship between smartphone addiction and sleep quality in adolescents. The study used a quantitative method with a cross-sectional survey design. Non-probability purposive sampling of 214 adolescents with inclusion criteria of 15-18 years old, students, Android smartphone users >2 hours/day calculated using the Slovin formula (5% error tolerance). Exclusion criteria: sleep disorders/chronic illness, iPhone users, or failure to complete the questionnaire. Instruments: Mobile Phone Addiction Tendency Scale (MPATS) for addiction and Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Analysis used the Spearman Rank correlation test. Results: 61.2% of respondents (N=131) had poor sleep quality, while 38.8% (N=83) had good sleep. In the low addiction group, 44% had poor sleep; in the moderate group, 60.8%; and in the high group, 64.5%. Statistical testing showed a p-value of 0.373 (p>0.05), indicating no significant relationship, with a correlation coefficient of r=0.06 (a very weak relationship). Conclusion: There is no significant relationship between smartphone addiction and sleep quality in adolescents. Sleep quality is influenced by other factors such as academic load, stress, and self-control.
