The way water resistance works in a phone is using seals where you can (around the screen, around ports etc). Where you can’t use adhesive seals like speaker grills and mics, you utilise surface tension with making a fine mesh, so water instead of going through, collects into a waterdrop on the surface of the mesh.
This is the reason the phone is rated for only 2-4 meters of depth. Any below that could break this surface tension because of the pressure is higher the deeper you go.
This is also why we won’t probably see IP69 on a phone, that test includes using water jets.
The weak point of this kind of water resistance is that steam can enter the phone easier, so bringing your phone into a steamy room, like bathroom after shower is a no.
It is highly unlikely that a liquid, that is very lightly sprayed onto your phone could actually enter the device.
I assume you use a case and a screen protector. Now even if just a tiny bit, but they still add to the water resistance capabilities.
Just an FYI, I sometimes see old iPhone SEs that got dropped into the bath and pulled out instantly. When I open them for inspection they often don’t have a single drop of water in them. Even though the SE has no water resistance rating, the phone is so tightly built, water has a hard time entering it during that really short time.
