iPhone 6 Plus Low current can’t be turned on for maintenance

Machine model: iPhone 6 Plus
Fault: Low current mobile phone can’t be turned on.

Maintenance process: I received an iPhone 6 Plus. Before the customer described it, I touched it in another place for maintenance. I moved the board once. After using Move Board (move the main chips to another motherboard)for more than two months, it was no booting, and the power-on current of the adapter was only 91 auto power off.
