Remember that consumers expect certain things from smartphones nowadays, which will mean that OEMs can’t just go back to the old way of doing things. An IP68 rating would be very difficult to obtain while still offering a premium-feeling device with an easily replaceable battery, for example. These are hurdles OEMs will need to get over to be in compliance.

this is straight-up BS. there were many phones with ip68 and user-replacable batteries back when sealing the battery in a phone was frowned upon. not all but many.
