It retains a 5ATM water resistance rating, making it suitable for swimming and everyday wear.

Under the hood, the S4 41mm gets the updated 4-LED + 4PD heart rate sensor module and a modified Xiaomi Xring T1 chip, now 35% more power-efficient. The watch supports real-time swim heart rate tracking and promises up to 8 days of battery life.
