BUT, after checking the battery does not contain 2680 mAh, 1430 mAh or even an original battery iphone 4S.
This 1054 mAh battery contains so 73.71% of the native iphone battery, namely that my battery used (native iphone) contenais still 82% of the native drums!
So I puts my old battery on the fields and returns the battery.
Do not think this is false advertising either for the reseller or other battery 2680 mAh autan dealer for that iPhone 5 or iPhone 4S 5S.
Moreover it heats all autan that native drums and finish are a revoir,
The icing on the cake after installation and verification already displays the battery charge cycle 300 therefore use a battery already, certainly for testing ...
So a so-called battery "new" and finally used .....
