How to troubleshoot my battery

I have a water damaged iphone 6 and I'm trying to isolate where the problem is.

I've removed the motherboard, cleaned it and all connectors with denatured alcohol, reassembled and ... nothing.

When I plug the phone into a charger with a USB meter in line, the charger is putting out 5.15V but 0 amps, so I know the phone is not taking a charge.

I've tried checking the battery itself with my multimeter, testing at the red and green locations.

No power.

When I tested the red and blue locations I got a brief .27 V reading and drained to 0 in a second or 2. Not sure what that's about. A capacitor charging and draining?

I also plugged the phone into the charger and read where the red and green leads connect on the motherboard.

No power.

This makes me think that, while the battery appears to be dead, the problem is possibly in the charging circuitry as well. Is this a reasonable guess?

Any ideas as to where to go next?

Thanks in advance,

From what you’re describing it sounds like your battery has next to no charge in it. For whatever reason when batteries drop below a certain voltage they lose the ability to be charged through the logic board. If this is the case the fix is simple: take the battery out of the phone and plug it into a battery activation test charge fixture, if the battery is quite dead it should draw about 1.8A through the fixture. Allow the battery to charge until it only pulls around 1.0A - 1.2A and then reinstall it back in the phone and plug in the phone. At this point the logic board should detect the battery and begin to charge it.

Since you mentioned water damage it is also possible that there is a short somewhere preventing charging. I would start by checking VCC_MAIN for shorts and going from there
