If the Xiaomi Smart Band 10 turns off while swimming, please refer to the following troubleshooting:
1. Low battery levels accelerate power consumption during in-water use and will result in automatic shutdown; it is recommended to ensure the device is sufficiently charged before entering the water.
2. Moisture remaining on the charging contacts can trigger short-circuit protection and cause the device to shut down; it is recommended to promptly wipe the device dry after swimming and keep the charging area free of moisture.
3. Damage to or aging of the waterproof seals can lead to water ingress, triggering the automatic shutdown protection mechanism; it is recommended to inspect the device for signs of physical damage or wear, and to refrain from further use in water if such issues are detected.
4. Extremely low or high water temperatures can trigger the device's temperature protection mechanism, resulting in a shutdown; it is recommended to use the device within standard swimming water temperature ranges and to avoid exposure to extreme temperatures.
5. Prolonged underwater use or exposure to conditions exceeding the device's waterproof rating can subject the device to excessive pressure, thereby triggering its internal protection mechanisms; it is recommended to limit the duration of underwater use and to avoid high-pressure water environments.
6. If it persists, please contact the official after-sales service for further assistance.
