The iPhone 7 plus is very easily misaligned and either not connected or the connector itself can be damaged due to this misalignment. Step one is to test the phone with a known good battery that has at least enough charge on it to power the phone on. If it doesn’t power on with a good battery, it is likely board level. There are also a few test points on the board you can test with a multimeter to see if you are getting power through the charge port and at least to the connector.
