I think a battery that prevents the device from running at full speed
because the unit shuts down would be considered to be "truly defective".

if *you* were the product manager, what would *you* do, given that
batteries age and there's no getting around that?

What I would do is figure out the problem, and then figure out a remedy.

I would propose to Apple Marketing two solutions and let them pick:

1. Secretly, permanently, and drastically throttle CPU speeds, hoping
nobody notices the subterfuge, or,
2. Openly admit fault & replace the defective phones with a trade in to a
re-designed phone when that redesigned phone is designed.

I'd let Apple Marketing pick the solution (since they are admittedly one of
the best marketing organizations in the world).
