With cameras you don't care about every mm of width, nor about how resistant it is to falls. With phones you do. I, for one, don't welcome that change. I'd be ok with paying someone a bit extra to replace the battery. I mean, I'd be ok if I had a battery die in my phone in the last 10 years, which I don't remember it did.
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…
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.
