I changed the battery in my smartphone 5 November and from the beginning I noticed that she did not take any longer than the previous load date of January 2014 when buying my camera .... .I am disappointed because I must put in charge several times a day !!!! which is not normal ...... this is unfortunate because the device itself is fine ... e ..I am sorry make that point but you ask me !!! opinion then I answer you at all !!!! honesty. With my cordial remembrance.
