Hey people. I purchased a Water Damaged Iphone 4S on eBay, to try and rescue it, it was in delivery for like a month, and i don't believe the owner tried the "rice trick". Anyway, I followed the instructions on how to rescue it, I disassembled it and took off the motherboard covers, put it in Isopropyl and brushed it with a clean new toothbrush. I cleaned the connectors as well, replaced the dock connector and replaced battery. The phone is powering on, i managed to restore+update to 6.1.3, but then I noticed it is overheating. The overheating occurs only when the battery is inserted, when I plug the phone without the battery to the AC or USB+Comp the motherboard doesn't heat up. This is really strange and kinda out of my league, I am from Israel so I don't have the option to "take it to apple", and I don't wanna spend loads of money going to a tech, because I fix phones for fun. I would greatly appreciate any professional advice. I researched and couldn't find any simple solution. One solution i found was to solder some new components on the mother board, and unfortunately I do not know how to solder. P.S. The battery doesn't charge, when I turn on the phone, it heats up and drains the battery, when I plug it in AC or USB it shows the sign of charging, but the battery keep going down and not up. Thanks in advance! -Michael.
