We've had thin smartphones with replaceable batteries 15 years ago. That was the standard. Galaxy S5 was the last one in that series, and it's not looking too different from today. It was even IP rated for water! Batteries also don't really die, but you get shorter and shorter life. When a device that barely could make it through 2 days of use now survives for less than one, an "upgrade" seems nicer than it really wo…
The S5 was IP67 rated but only if the USB port flap was sealed. Modern phones like the S24 and iPhones are IP68 rated without covers. As someone who spends a lot of time outdoors in the rain, giving up superior IP68 water resistance for a replaceable battery that I'll never replace will be a downgrade for me.
Urban rainproof phones like S24 and iPhone aren't actually intended to be left drenched in mud or seawater, so they don't have to be equipped to be resistant against pieces of soil or soaked driftwood jammed in the charge port.
