I'm not satisfied with this product, as this 1230mAh battery falls HS after 10 minutes when it should take 2 hours. My 1030mAh battery lasts me 30 minutes, so that the longer m ****; it is normal that ??? I demand a refund or replacement of the defective item, because the 1230mAh battery should have a autonymy higher than 1030mAh, and not the reverse.
