Battery must be connected to the phone's board and fully charged.
You have to use the modified USB cable according to this schematics.
Connect phone to USB port placed on the backside of PC (motherboard's USB port)

The resistor is 10K same schematic connected.
I use All USB ports of my PC and on my second PC - same

Here will see battery level and colors of resistor: https://disk.yandex.com/i/zOpXvPc5tRdS2A
