The battery therein is stamped Samsung, made in Japan but assembled in China ...
It has much the NFC antenna but its autonomy hardly equal that of my original battery yet 7 months old.
The descriptive (picture and characteristics) is lying here for months since suggesting that this is a packaged product / packaged by the manufacturer so it is not so!
This is what led me to pay 17 instead of 8/9 for a "naked" battery as Amazon proposes.
One catch me ...
I think the product is not an original product Samsung and that it is a counterfeit.
