Yeah, I had the same exact problem with mine. The port is very loose and it looks like a few of the gold pins are bent inside. If i press really hard on the charger it charges sometimes, but I can not hold it all day so my phone can function how its supposed to. This started three months ago, thinking it was the charger, I bought a new one. I don't know if I can get a new phone for this as an exchange or if it is too late.
