Not charging after battery replacement
I have an iPhone 5 that I got in 2012. When I first got the phone, I managed to get it in a small table puddle of water. Long story short, there didn't seem like there was any damage and I've used the phone successfully up until about 6months ago.
At this time I noticed a screen bulge, but did nothing as I thought I had bent the phone. However, up until a 1-2 months ago I noticed the bulge getting bigger and I finally took it in to a store. They advised that my battery was bulging and would need an immediate replacement. The replacement was going to cost around $90 and a quick youtube search and google search revealed what seemed to be a very easy repair with a "new battery" and tools with delivery for $13. Obviously I choose the $13 gamble.
The battery came, I replaced it "successfully" but the phone refused to charge. More google searching and it seems I may damaged the logic board, my dock may have been damaged or the "new" battery which are really reclaimed batteries was too old and wouldn't cycle any more. I took my phone to the store who opted for dock damage.
They have had it for 2 weeks and I've finally gotten my phone back, but they said that the battery that was supplied, was in fact faulty, my dock works fine, but my logic board is damaged from water (one sticker is red) and is potentially not allowing the charge.
Given that it charged fine before the battery replacement, is this likely? I don't have any other iPhone 5's to test and can see no obvious damage anywhere. Any thoughts or suggestions?
I will have to end up getting a new phone, but this might be a nice IT project I can tinker with for a while and if I fix it will have a spare phone.
Thanks to all for your time
