Battery life is approximately 6–15 days.
You can check the bracelet battery status anytime in the app under “Measure.”
Battery autonomy may vary depending on how often the bracelet needs to capture physiological signals to support long-term trend visibility and system performance. More frequent signal collection may use additional battery over time.
Factors that may influence battery autonomy include:
skin tone
arm hair
small everyday movements
physiological signal quality
overall usage patterns
