So I have had a problem charging my galaxy 3 for a few months now, it takes about 5-6 hours (if not in use) to get past 20-30% If i am using the phone it doesnt charge and will go down. I have tried 5 different chargers and none seem to help. I took it to cspire and they told me my charging port in my phone was loose and that its not covered under the warranty as it is a user problem??? i could possibly get it fixed somewhere else. Wondering if anyone else has had any problems like this and what they have done? i have thought about buying extra batteries and the charging port for the batteries, has anyone bought backup batteries for the galaxy 3?
