true. the battery almost always outlast the phone unless the battery is
defective, in which case it's replaced under warranty.
it's also not difficult to replace an internal battery, it just
requires a screwdriver to open the case instead of a fingernail to pop
off the back. a few phones are more involved but they're the exception.

they won't be kicked off, although phones without volte are already
fairly old and in need of replacement for other reasons.
without volte, people might not be able to make voice calls, but
otherwise, the phones will continue to work as before for all other
tasks. voice calls can also be done using a voip or messaging app,
although that's less convenient.

at&t does not have a whitelist. they have a *compatibility* list.
phones not on that list can be used but will probably have issues.

yes it was due to the battery, which has been explained to you by
numerous people many times.
all batteries age, which reduces its ability to source the same current
it could when new (higher internal resistance). peak demands that once
were not a problem might now be a problem.
it's not possible for any chip to extract more current than the battery
can itself provide. what apple did was better manage peak demands from
an aging battery
several android phones also had sudden shutdown issues, just like
iphones.
this is not unique to phones and affects anything with a battery,
including motor vehicles, cameras and much more. for example, a car
battery that can run the radio or headlights might be too weak to start
the engine, which is a peak demand.

most phones last 1-2 days in typical use, making that needed only in
extreme cases.
