My samsung mega 6.3 wont really charge after several attempts / repair

Hello guys, i have used my samsung mega 6.3 for 2 years. i love this phone so much i dont want to buy a new one. I have changed the battery, i have used several chargers. Sometime it works sometimes it is not. I have changed the charging port recently but still the same. I have formatted my phone twice. I guess i have done everything. Is there any other solution?
