One of the most curious and useful functions of the Apple Watch is the one that allows you to expel the water that has accumulated inside it; although it is also the one we usually think about the least.
The Apple Watch has always been waterproof, but it wasn’t until the second generation that it was actually possible to submerge them, and use them while swimming or bathing. It’s one of the best things about it.
That’s because, while the watch itself is waterproof, there are parts that are outdoors, such as the built-in speakers and microphones. So, if you wet them, you may find that they sound bad or stop working.
The most curious feature of the Apple Watch
To solve this, Apple implemented the Water Mode, with the ‘Waterlock‘ function, which is able to expel water that accumulates in the speakers and the rest of the device. It is automatically activated when we turn off the Water Mode in our watch, or we can force it to run in the Control Center and click on ‘Waterlock’.
This has led to some interesting discoveries about water physics on that scale. For example, one problem Apple encountered when developing this functionality is that the vibration of the speaker can also cause droplets to re-enter the device.
To solve this, the vibrations stop just at the right time so that the water gets trapped in the grill, and they are activated again so that it can be expelled completely; something tells us that this pattern is not by chance, and that it has been studied, as well as the fact that there are ten such cycles.
