Water damaged 6s Plus draws current in spikes.

Symptoms

No boot, no signs of life. When plugged into charger, draws 4-5mA, and then on a regular interval, draws 100-300mA for a split second.

What's been done

Completely torn apart, motherboard and various other components brushed and ultrasonically cleaned with 90% isopropyl.

Additional notes

The battery, upon connecting to a functional iPhone 6 plus, comes to life and charges, but after plugging it into the defective 6s, it cuts off, no longer outputting voltage to its' connector.

Any ideas where I could start diagnosing this issue?

When dealing with a “dead” phone, you have to start at the beginning and check PP_BATT_VCC, PP_VCC_MAIN and PP5V0_USB. I would start by checking to see if those rails are shorted to ground. If one of these rails is shorted to ground, then you will need to identify what is causing the short. It could be a bad decoupling capacitor, conductive debris or defective IC that is directly supplied by those rails.

If they are not shorted, then you can connect, preferably, a known-good battery (or a current limited DC power supply with the appropriate connector adapter) to see what voltage you measure. If the voltage is low or lower than the battery voltage (which you measured before plugging it in ;>), then there could be a short circuit on secondary subsystem that is causing the battery or DCPS to be current-limited.

If you are measuring the proper voltage, then you move onto the PMIC and check the voltage rails it generates. Focus on the CPU/GPU/SOC lines as well as the SDRAM, NAND & Tristar lines.

So start probing and let us know what you find.
