Disassemble the phone and connect with DC power supply, find large current.

Then use rosin inspection method, apply DC power to find out the shorted component.

It’s a filter type capacitor C3018 which related with VPH_PWR power supply get shorted.

As we can see, it’s just located around the Wi-Fi chip.

Just tick it off directly, then test.
