It won't work without the chip.
Most of the functions on the phone are almost integrated on the motherboard in the form of chips, including the processor part of the core. Losing the processor means that the phone's system cannot be run and the device cannot boot.
If there is no CPU, system instructions are not processed and the system cannot work. Without a GPU, the graphical interface cannot be sketched (the CPU can do it, but it is slow and obviously not up to modern interaction requirements); No ISP will cause the camera part can not be processed, can not even shoot or even basic image light adjustment can not be done; Without baseband, you can't communicate with cellular networks (not just phone calls, but network connections).
The chip is a general term for the above parts, and the loss of the chip will lead to the loss of all the above parts. In addition, there will be a large number of power management chips in the battery, and it is a very risky thing to lose this chip and charge the phone.
