Why battery and charging matters on the Prime 4
A full charge cycle should comfortably cover a day of typical use for the target customer.
Cash flow is the quiet constraint behind battery and charging: the cheapest option is rarely the one that frees the most working capital.
USB Type C has become the expected standard and reduces return rates caused by cable confusion.
