iPhone SE not powering up

iPhone SE A1662

Power button no response. Power button feels good.

Attach cable from PC using iTunes to iPhone no response

Battery voltage low and was replaced

Screen removed and tested okay

Water mark shows a slight discoloration

No corrosion on connectors

Battery to logic board connector pins look okay, and ground is okay.

Draws 15ma when turned on and then 11ma.

Any assistance would be appreciated. Also looking for iPhone service manual test points on the logic board, thanks.

Edit 5/18/2021:

Measured 500ma draw after cleaning battery leads.

Someone has been in here before me.

Extra epoxy added.

One part of a wire broken off from connector the end was terrible soldier job.
