My battery drains while charging!!!

[AC Question]

I'm having the Samsung Galaxy S3 and the battery drains while it's charging. I tried changing the charger, the battery, the cable,... but nothing works. I even tried cleaning the charging port on my phone, but that still didn't help. I do not use my phone while it's charging, and eve when I set it on airplane mode to prevent drainage, the battery charges very very very slowly. Please help!!!!!!!

Might be time for a new battery, have you been using it a few years now?
