You will not be able to connect it directly to a computer. In marketing, this will be to meet rigorous water safety standards.

Making devices water-proof is also a marketing scheme to avoid replaceable batteries :

Some manufacturers are already eyeing an exemption for batteries used in “wet conditions” to opt out electric toothbrushes and possibly wearables like earbuds and smartwatches. The exemption is “based on unfounded safety claims,” states Thomas Opsomer, policy engineer for iFixit, in Repair.EU’s post.

Despite the coming up regulation on batteries and waste batteries by the EU Council batteries in water-proof devices will probably be exempt from being replceable, because the water proof feature of the device cannot be guaranteed. This undermines the right to repair and manufacturers can hope that customers replace their entire devices soon. Making phones water-proof is a loophole to seal off the device so that it is not to be repaired, at least without keeping the water-proof features after repairing.
