If the phone is making the charging sound and you have replaced Hydra, Tigris, Mosfet q3350. I would look at Q3200 and Q3201 this is usually where I start on the iPhone 8 charging circuit. These two fets might look all right but I would lift and re seat them.

I hate it when repairs end up like this. Diode your gas gauge circuit with a known good board. Have you got a tristar tester?

Nope, I don’t have tester. What check on board with diode mode?
