Phone won't charge after replacing lightning connector & battery

Thanks for your question.

Sorry for your troubles.

When replacing connetors, buttons, or ports, (parts that are lower on the price margin than the more expensive components of devices) it's a good idea to buy two or maybe three of the parts to circumvent having to deal with defective parts.

This may be your situation. Defective lightning connector. It happens in the repair world four sure. Parts just go bad sometimes.

Seems like the short of it to me. That would be my next step if this was my repair.

Hope this helps.

Good luck.
