What is the drainage function of the Redmi Watch 5 Active?

The watch supports the drainage function, which can be used to remove water from the speaker after swimming or from everyday exposure to moisture. The principle of drainage function is to play the sound of a specific frequency, let the diaphragm vibrate, and use the vibration to shake out the water that invades the speaker space to protect the speaker from water erosion.
To activate the drainage function, please refer to the following steps:
1. Slide on the watch face home page to open the control center;
2. Tap the drainage icon;
3. After draining is complete, shake your watch to clear water from the speaker.
