Have the Dino Cell battery in Galaxy S3 Samsubg Smartphon and am very happy with it so far. The battery lasts a lot longer by, I have recorded a lot faster computing power of the device and the charging time is despite significantly more capacity considerably shorter alsbeim original battery from Samsung, this failed after 7 months (shortly after Samsung battery warranty period). I know from my circle of friends, that this battery will most likely survive the life of my cell phone.
