Water Damage - Possibly battery
About 2 months ago my friend said he woke up to his phone in a puddle of water. He dried it off and tried to turn it on and noting happened. He recently asked me if I could take a look at he phone since his back-up phone broke. I've been looking around and most people said that the first thing to be damaged is the battery I was curious if I could just replace the battery and it fix the problem?
Also, a few years ago I dropped an iPhone 4 in water and took it to someone and he just took the battery out and put it back in and it fixed it. Is there a chance that could be the case for my friends phone?
Is this a good question?
