After one week, not working properly

This commentary relates to the battery battery (Adaptor)
It worked one week then by putting him in charge, it takes a long time to load, sometimes, all night, therefore obliged Dinter-change with battery Q10 because the sector is in the phone , it goes faster. The worst part is that once charged, the battery discharges soon after, it's really disgusting, so I do not know if mine is that all models or, at least, if it ' is the case for others, do not hesitate to report it.
The seller should replace it, because that's really a waste. A big thank you to the seller and Amazon,
