Ever since it was announced that the Galaxy S6 wouldn’t offer
either a removable battery or a microSD slot, there was all sorts
of kerfuffle on tech blogs, and the comments therein: people said
that they bought Samsung stuff specifically for those elements,
and that those were key things which set them apart from the
(reviled, in their eyes) iPhone range, which has never offered a
removable battery or slot-in storage.
However, I’m pretty sure that Samsung’s move is not only
idealistic — not having to make the back removable avoids all
sorts of design compromises — but also driven by clear data.
If swappable batteries were a meaningful mass market selling point, Samsung wouldn’t have changed sides on this. Years behind.
