I absolutely despise that Apple made non-replaceable batteries the norm, and most of us have begun to accept this as "the way things have always been". Every cell phone I had before the iPhone came out had an easily replaceable battery before we all became a slave to Ives' "Preciousssss" demands for minimalism.
Edit: Folks seem to be misunderstanding why I brought up Apple. I in no way think they are now worse than any other phone manufacturer when it comes to irreplaceable batteries. But AFAIK the iPhone was the first phone to have a glued-in battery, and that has since become the norm. They have essentially helped lead the way in convincing consumers that replacing the battery shouldn't be an easy, user-accessible operation.
And I kind of care about waterproof phones. Before you bring up the old Samsungs, if you didn’t put the battery on just right (and Samsung warned you about it), you would lose water resistance.
I would imagine nonreplacable batteries would happen without them, but it does seem like every other brand copies whatever crap Apple decides to put out, especially the aesthetics. There are so many very obvious apple clone products.
