iPhone 5S little water damage. How to clean it?!
Hello, i've got my hands on an iPhone 5s gold wich has never been openend before. But it has (sadly) water damage. I took it appart today and i cleaned te connectors of with 70% denaturized alcohol. Still no power.
The water damage is on the bottem section where the battery connector and dock connector is. And there was a littlebit of rust on the sim slot. I removed the logicboard but there are no stains or rust/corrosion on the big EMI plateon the underside. The battery connector got corroded and so for the actual battery connector so i think i have to replace that one. But the dock flex was fine but it still dind't powered on without the battery connected while plugged in the charger. Is that normal? Screen is absolulty fine i tested this one on an known working iPhone 5S logic board. And it was only at the bottem where the battery nonnector is and where the loudspeaker ect is. How can i completely clean it and is a battery replacement needed? It doesn't turn on without.
Touch ID connector got a veeeeerrryyy little bit of corrosion to but thats already gone! :D but the water damage was minimal but it rusted due to its time been like that.
Every answer is more then welcome!
Btw its an gold iPhone 5S]
Is this a good question?
