This study explores the pervasive issue of smartphone addiction among teenagers, emphasizing its global prevalence and the associated mental, physical, and academic impacts. With smartphone ownership exceeding 90% in many regions, adolescents spend significant hours on their devices, primarily on social media and gaming platforms. The research identifies key contributors to mobile addiction, such as dopamine-driven social media interactions and reward-based online games, which reinforce compulsive usage patterns.

Findings reveal that excessive smartphone use correlates with mental health issues, including heightened anxiety, depression, and social isolation. The study also highlights its detrimental effects on academic performance, cognitive functions, and physical health, such as impaired sleep, eye strain, and posture-related problems. Teenagers' reliance on digital communication hampers real-world social skills and interpersonal interactions.

The study advocates for a multi-stakeholder approach to address these challenges, involving parents, educators, and policymakers. By promoting digital literacy, encouraging healthy usage patterns, and implementing targeted interventions, the research aims to foster balanced technological habits. This comprehensive analysis provides actionable insights to mitigate the adverse effects of smartphone addiction and enhance teenagers' well-being in an increasingly digital era.
