Could you give some examples of these things, please? All waterproof hardware I have ever owned (phones, cameras, flashlights, watches, etc) doesn't have user-replaceable batteries. In all cases the batteries need to be replaced by a specialized shop and the waterproofness is tested afterwards in a special machine - and it's not always a success and the job needs to be redone.
Note that there is a significant difference between "water resistance" and "waterproofness".
Samsung Galaxy Xcover6 Pro was released in July and has a removable battery, headphone jack, and has the same IP rating as the S9
A few companies have business/military phones that still have most of the features people were used to. They are a little bigger, but you don't need a case.
Hmm, nice but that's really a very different kind of device. I don't want anything so bulky - this is like double the thickness of the S9. I'm not using any case, no need - the Gorilla glass is more than enough to survive repeated falls on the road when I was getting out of a car.
Rugged 2-way radios, not just waterproof, but designed to float and to turn on the lights when dropped into water. Perfectly replaceable battery pack, interchangeable with the regular NiMH batteries. All it takes is literally rubber inserts that you need to pop off to access the screws.
That's an exaggeration. They are no bigger than any other phone in a rugged case. If anything a bit smaller really since the "rugged case" is integrated into the phone. I have my work iPhone in an otterbox and its far bulkier than that.
I use my Samsung S9 without any case since the Gorilla glass is more than sufficient for me. It had its fair share of falls on the road when I was getting out of a car - still looks almost new. It even slid down from the top of a roof into the gutter when I was fixing an antenna there - few minor scratches on the back, nothing more.
My Yaesu FT65R is IP54 and FT5DR is IPX7. The Olympus OM1 is IP53 (only camera I can think of with an actual IP rating) and Pelican makes IPX7 flashlights. All of which have easily replaceable batteries.
I see it all the time in radios. I'm a ham so I own a few and any radio with an IPX rating more than being in the same zip code as water will be both waterproof and have removeable batteries.
