Why is the heart rate inaccurate on the Xiaomi Watch 5 when swimming?
During swimming, if the Xiaomi Watch 5 is worn too loosely, the gap between the watch and the skin will be too large, causing water to impact the sensor during movement, resulting in poor PPG signal quality.
To ensure data accuracy and reliable heart rate monitoring, please refer to the following:
1. Tighten the watch strap appropriately, ensuring there is enough slack to insert one finger between the strap and your skin.
2. Make sure the sensor on the back of the watch is in close contact with your wrist.
3. If the issue persists, please contact the after-sales service for further inspection.
Note:
Due to water movement in the underwater environment, heart rate measurement will be less accurate than on land.
