You need to start probing the logic board for shorts on the power rails. If you just randomly start changing IC's, you could get lucky but you could also be applying too much heat on every other component for nothing. That could lead to disaster.
Find the schematics for the iPhone 6 (they are out there!) and start checking PP_BATT_VCC & PP_VCC_MAIN. Then start looking at all of the voltage rails to U2 and from the PMIC.
The problem with water damaged boards is there may still be corrosion ongoing underneath the IC's.

Maybe the power management IC is dead.
