ELI5: Why does a dead laptop turns on right away when plugged in but a dead phone must charge for a few minutes before turning on ?

A laptop can run directly off wall power; a phone cannot.  Even when a phone is plugged in, it's actually running off battery power.  So when you plug in a dead phone it takes several minutes to build up enough charge to power itself up.
