Does your phone power on automatically upon plugging in a "dumb" USB charger, i.e. a charger that conforms to the USB Battery Charging 1.2 specification? As a note, most USB chargers that do not have a Type-C port are of the "dumb" variety.
If the phone doesn't power on automatically as described above, most probably there's something wrong with the AXP803 (which is also commonly referred to as the power management IC or PMIC for short). The PMIC is hardwired internally to power on the phone automatically upon detecting a valid power source.
