the battery can be removed and replaced, it just requires a
screwdriver and something that is not needed very often.

If by "something that is not needed very often" you mean special tools
they may come with the replacement battery as they did in my recent
battery replacement:

sometimes the tools are included as part of a kit and sometimes they're
not.

The wife's iPhone battery swelled up so much it popped the case
open by a quarter inch. I left it stored on a metal cookie sheet (as I
was worried about fire) until I got and installed a new battery. The old
battery looked and felt like a mylar balloon when removed. The new
battery was $30 USD including the tools so it didn't set me back too much.

that's a defective battery and apple will replace it for no charge, as
it poses a danger to you and those around you.

normal wear and tear, however, is not covered.
