The number of people using their phones in the hot tub, or in the sauna, astounds me on a regular basis. I can't imagine doing that. But, with modern devices being genuinely "drop them in the pool" grade waterproof, neither does it seem likely to be a problem.
I'll agree on thinness, though. The number of phones in massive, chunky cases says "A lot of people don't care about thin."
and the number of people who desperately look for a way to replace their batteries or upgrade to a new model just because their phone battery degraded is quite saddening.
They care about thin, but they also care about the fragility of metal and glass backs.
Manufacturers put water-sensitive indicators in electronics to flag this during warranty claims. Before water resistant phones, people would desperately google for how to save their phones.
> don't care about phone thinness either
There are rumors the next iPhone with have a thin model. You should also look into the original Motorola Razr. It was the original sexy phone precisely because of how thin it was.
However it’s worth noting that in the era you described where phones had replaceable batteries, water damage was also a lot less permanent.
Back then, you would whip the battery out, leave the phone in rice for a day, then it would power up the following day as if nothing had happened.
These days I couldn’t see that working even if you could remove the battery. And when you also factor in how much more essential phones are to our every day lives (they’re our wallet, plane boarding pass, health monitors, location tracking for nervous parents, etc. we don’t even remember important phone numbers like we used to). Regardless of whether you agree with all these use cases, it does result in a scenario where water resistance is a lot more important than it used to be.
It’s certainly true from my experience but perhaps others have had different experiences?
Plenty of phones had replaceable batteries, water resistance, and headphone sockets.
Of course, that was before Apple issued the edict that it was impossible.
