Water damaged 6s Plus draws current in spikes.
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.
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?
