Bench PSU? Whats wrong with two flyleads from the phone charger?

The phone charger input is likely at a different voltage to the natural
cell
voltage of the battery (eg 5V from USB v 3.6V from lithium ion). The
battery charge circuit might not like that.

As it is, you might still have difficulty: the battery smarts won't be
there. Depends whether the phone will power up if it has a voltage but
can't read status from the battery.

Phone batteries are not *usually* that smart

Oh yes they are.

Whether the phone takes any notice is another matter
