They warranty the repair for 60 days, if it has the same problem they have to repair it for free.
As I have seen, Samsung already knows how to fix this issue as it's not new anymore , thousands of them have the same problem from different models. Trust me, if they cannot fix it properly, file a complaint with BBB. Repair centers scare of complaints filed with BBB more than Samsung as they don't want to lose the business with manufacturers.
Consumers are protected by law but I know many users don't know how to take advances of it.
This is an example of a repair in March 2015, they actually resolder the connector only, not replace it.
Replace the connector requires a lot of work as the motherboard has to be removed completely and the old connector has to be taken out.
It Works. Battery connector replaced. Smoooooth - Post #100
The first time they did not know how to fix the issue, the second time they fixed it correctly.
This is a repair from a repair center, they soldered the battery cables directly to the connector to fix the loose connection issue. As I know, a repair center is not allowed to modify customer tablet unless it gets the instruction from Samsung
