Shows charge symbol but it is not charging, any ideas?

I am a smartphone and tablet repair technician so I have done close to a hundred iphone 4 and 4s. This 4s need the charge port flex replace because it wasn't charging. After the replacement was done, I plugged in the charge cord and the phone got stuck in a boot loop. After troubleshooting it for a few minutes I decided to change the charge port again. Installed a new one and this time when I plugged the cord in the phone booted up fine. I let it sit on the charge for a few minutes while I did other repairs. When I came back to the phone I notice that the battery percentage did not go up at all, so I place a new battery in and repeat the charge process. Wher I return to it again, same problem, battery percentage did not increase it actually lowered a percent. The charge symbol is displayed but not charging. Since that I have tried 2 new batteries, 3 different cords and chargers, home+wake/sleep restart, and put it into restore mode (cancelled that before actually restoring) so I am stuck.

When the phone is plugged into charger and it indicates that it's charging hold power button and turn off now leave 30 minutes and come back and turn on and see if it has charged battery
