I have had this phone for about 4 years now. It stopped charging at the beginning of last year. I have tried multiple chargers on this phone to make sure it wasn't just the charger. About 2 months after this I ended up sending it out to a person who would look at it and "see what was wrong". He claimed nothing was wrong with it and (i was a minor at this time) my parental figure had to get involved. This guy ended up just replacing the battery with a brand new one and sending it back. It turned out it was not the battery. It still would not charge at all. I've been looking into maybe trying to see if it's the charging port, but I'm unsure. Its so expensive as well and I'm too scared that I'll mess up the phone if I do it myself. I have no experience with repairing phones.
