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 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.

Samsung Galaxy S5 was the last one that attempted it. IP67 with a removable back cover and swappable battery.

Back when replaceable batteries were the norm, I had two Blackberries that survived going through the washer and dryer.

> I've even seen people literally swim with their phones and not even question if it was a bad idea.

Which is funny to me, because even with an IP68 phone, I get worried if I even splash a little water on it.

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...

I was wading through water with a 3310 in my pocket in 2006. Battery was fine and it worked after it was dried. There was a problem with the keyboard though but that was a cheap swap. And this was a phone without any water resistance.
