Battery controlled to give a facelift to my smartphone .... supposedly sold new and battery takes even less than my original battery! In short unnecessary purchase especially as coupled to a telephone scam: supposedly the driver did not have a readable address so I had to remind the carrier (cost 1.35 + 0.34 the call per minute), obviously on answering machine .... In the end, which is less powerful battery (qques hours) than the previous one and in addition, the price of the scam (I do not know if the seller has to do with it ?? !!) high the price battery!
