Core Tip	This multi-center observational study of 16668 university students reveals a U-shaped relationship between objectively measured mobile phone use time and depressive symptoms, indicating that both overly short (0-3 hours/day) and long (≥ 9 hours/day) usage increase risk. Mobile phone use time was positively associated with anxiety symptoms. Notably, mobile phone addiction, posed a substantially higher risk for both depressive and anxiety symptoms than mobile phone use time alone, underscoring the critical need for interventions targeting mobile phone use time and addiction.
