Which phones? I ask as someone that's had to replace multiple phones after a trip through the washing machine.
Modern phone water resistance is incredible. I've even seen people literally swim with their phones and not even question if it was a bad idea.
Fifteen years ago, I had a Garmin GPS (admittedly not a phone, but similar form factor) that survived a week of knocking around the bottom of a raft.
The battery compartment had a rubber gasket and some very tight screws.
Samsung Galaxy S5 was the last one that attempted it. IP67 with a removable back cover and swappable battery.
Samsung Galaxy S5 is the first one to cross my mind.
Not really comparable perhaps - but I had a Ericsson t18s or similar that went through a full 60C cotton wash cycle (being on at the start of the wash) and was fine after drying off.
The thing is - if the battery had been destroyed, that could have been replaced...
Samsung still make the rugged Xcover range which has both replaceable batteries and waterproofing. And 3.5mm jacks too.
These devices are mostly sold in enterprise environments (eg field use, factories) and as such get a lot of wear and tear. But they hold up well. They're not ultra rugged but a good compromise. We use tons of them in our factories, we replaced DECT handheld phones with the Xcovers loaded with ms teams. Not an ideal setup (teams for mobile kinda sucks) but at least this way they can easily communicate with people in the offices.
