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]
Hey LorenzoVHH, try to disassemble your device then clean each and every part with 99% isopropyl alcohol. Then if it doesn’t turn on or charge, you might have to replace some parts. Do that first then let me know how it goes. -Let me know how it goes.
LorenzoVHH,the very first thing you want to do is to not try to restart the phone. This may further damage your phone. The next thing to do is to clean it. Disassemble your phone using this guide Then clean it with +90% isopropyl alcohol. remove all the EMI shields. You can not properly clean it with those on. Follow this guide, and even so it was written for a 3G all the points are still pertinent to your phone. yes you can soak the complete board in it. Time does not matter. While you clean your board, check for any obvious damage, like burned or missing components etc. Double check your battery connector. When it is properly cleaned, replace the battery. All these steps are to avoid delayed failure caused by corrosion. Once all this is done, reassemble your phone and reevaluate.
