Is my phone's charging system working?

テキスト:

Hi, so I dropped my samsung phone into the sea in winter and I left it on my drawer for months. Now I tried to fix it, took off the motherboard shields and cleaned the corrosion. After that I replaced the charging board. Now I measured the end of the main flex and it shows 5v. When I measure the battery connector it shows 2.1volts. Is this normal? Should I pay 70 dollars to replace the screen and battery or is it a waste? Please answer, it is a very important phone to me, thank you

@oldturkey03 I cleaned all corrosion tho, even under the sheilds... Could it indicate anything else? Also now that I am checking with my multimeter I check 2.4 volts at the battery connector while charging instead of 2.1 volts. Also heres a photo of the motherboard

Also I got the ammeter, it shows 5volts and 0.00 amps. What should I do? My new battery also reads 2.65 volts with the multimeter, is it normal?
