I still do not agree with that rule. Replacable batteries are at odds with water tightness. I would have bought more phones if mine didn't survive water to a great extent. I think instead the regulation should focus on making parts available and phones reasonably easy to repair. This will most likely include switching out seals, which are needed for the protection from water.

I think batteries can technically be submerged in water and discharged safely but it's an engineering challenge. As long as the rest of the phone is waterproof I think we are okay.

  It is significantly more complicated than that. Water isn't just dangerous because it short circuits, but because it also attacks the materials. You do not want water in your phone, seperating the battery compartment also increases thickness and complexity.

    Super thin phones are impossible to hold without the hefty case.

      But most phones arent super thin. Imagine adding a replaceable battery and thickness to those.

        I remember having Samsung Note 4. It had user replaceable battery and I had it cased. No problemo.

    Exactly my point. It's possible but complicated.

  The one I know of was a Samsung which didn't really succeed at water tightness.

    Are you talking about the S5? It has a removable battery and has an IP67 rating so it should definitely be watertight.

The risk with these mechanical covers is that they deform under pressure and let water enter. It is difficult engineering challenge and anecdotally it didn't work that reliably. Glueing phones makes the engineering simpler as it removes the need for any kind of screws and mechanical locking mechanism, instead all electrical conponents can be fit very tightly into the interior of the phone.
