We're talking about a single cell for a smartphone, not something like an EV battery pack.

Sure, maybe there’s less need for charge balancing in a smartphone battery, but the rest of the constraints still apply - fast charging is hard!

Limiting the current to what the cell manufacturer specifies is not hard.

I don't think fast charging is a good idea anyway because it wears out cells faster, but that's another rant...
